The Conservative Origin of Income Taxation

Abstract
This paper examines the adoption of income taxes by Western economies sincethe 19th century. We identify two empirical regularities that challenge predictionsof existing models of taxation and redistribution: while countries with low levels ofelectoral enfranchisement and high levels of landholding inequality adopt the incometax first, countries with more extensive electoral rules lag behind in adopting these newforms of taxation. We propose an explanation of income tax adoption that accountsfor these empirical regularities. We discuss the most important economic considerationof politicians linked to owners of different factors, namely, the shift of the tax burdenbetween sectors, and examine how pre-existing electoral rules affect these politicalcalculations. The paper provides both a cross-national test of this argument and amicro-historical test that examines the economic and political determinants of supportfor the adoption of the income tax in 1842 in Britain.

1 Introduction
The 20th century is the era of the Tax State (Schumpeter, 1918). The size of government
expanded at an unprecedented pace (Lindert, 2004). The development of massive spending
and investment programs transformed the state from a mere security provider to a central
actor in all aspects of economic life. Importantly, this transformation was only possible
after the adoption of the income tax and its unprecedented revenue generating capacity.
Such extractive capacity makes the income tax the most advanced fiscal instrument to date
(Lieberman, 2002; Tilly, 1990). In the words of Johannes Popitz, the income tax is the
“queen of taxation” (Popitz, 1926).
The income tax facilitated an increase in the extractive capacity of the state because
its adoption went hand in hand with the development of institutions that tapped into and
collected previously undetected revenues. In particular, the implementation of an income tax
required the creation of a sophisticated tax administration capable of verifying the income of
higher earning individuals in a given economy and ensuring the compliance of the latter with
their tax obligations. Thus, to understand this fundamental shift in the extractive capacity
of the state, we need to characterize the political conditions under which elites agreed to
subject their income to public scrutiny, the institutions and mechanisms set in place to verify
income, and the allocation of the tax burden across individuals who derive their income from
different sources.
Existing explanations of fiscal capacity development share one common over-arching
theme: war is the driving motor accounting for the expansion of the modern state (Dincecco,
2011; Scheve and Stasavage, 2010; Tilly, 1990). By contrast, domestic economic and political
variables that account for the decisions of political elites to invest in the development of in-
stitutions of fiscal revenue extraction have received less attention.1 While acknowledging the
importance of war, this paper turns to an examination of the latter political factors. While
the introduction of income taxes has the potential to generate higher levels of revenue, it

also imposes a higher tax burden on individuals with higher levels of earnings. The adoption
of this novel form of taxation raised a range of political questions about the allocation of
this tax burden across owners that derive their income from different types of assets. Our
paper seeks to identify economic and institutional factors that facilitate the resolution of
these distributional conflicts and the adoption of income taxes.
In examining the variation in the timing at which current advanced economies adopted
income taxes, Aidt and Jensen (2009) uncover an empirical regularity that runs counter to
the predictions about the temporal sequencing between democratization and taxation derived
from canonical redistributive models (Acemoglu and Robinson, 2000; Boix, 2003): namely,
non-democratic countries with restrictive suffrage rules pioneered the permanent adoption of
income taxes. Our paper seeks to present an explanation to the puzzle posed by the sequence
of the income tax adoption in the developed world. That involves understanding the political
and economic motives of elites in non-democratic contexts to adopt a tax that imposed a
higher burden on high-income earners. Given that neither the Meltzer Richard model nor the
more recent literature on democratization and redistribution provide useful tools to address
this puzzling empirical regularity, our paper takes the task of formulating an explanation
that accounts for the non-democratic origin of the income tax. Rather than invoking elites
anticipation and fear of potential redistribution under full suffrage, we contend that one
needs to clarify to immediate economic and political advantages provided by the income tax
to incumbent elites in countries with restricted electoral rules. We argue that, in addition
to their capacity to raise new revenue, income taxes provided specific political and economic
benefits to political incumbents in limited democracies. Our theoretical explanation specifies
these advantages.
Consider first the economic benefits of the new tax. The incidence of the new income
tax across different sectors is rarely neutral. The design of income taxes inevitably creates
winners and losers between sectors that face a higher or lower tax burden. All non-democratic
countries adopted income taxes in a period of massive economic and political change, at a
3
time when the economic power of incumbent landowning elites was severely threatened by
the rise of a new economic elite linked to the emerging manufacturing sector. Anticipating a
future decline in economic power, politicians representing the interests of landowning elites
regarded the income tax as a tool that could rebalance some of these economic losses by
imposing a higher tax burden on the industrial sector. In adopting the new tax, incumbent
economic elites placed thus a high political priority on the creation of institutions that
monitored less visible income and also on the taxation of more mobile assets.
The above discussion implies that politicians whose interests are tied to owners of fixed
assets were more willing to support the adoption of the new income tax as compared to politi-
cians representing the interests of mobile asset holders. While the risk of capital mobility
imposed an upper bound to the tax rate levied onto capital gains, it did not prevent landed
elites from imposing, when possible, higher tax rates on industry and finance than on land.
We test for this logic by examining the consequences of differences in the bargaining power of
landed elite in the national parliaments of 19th century Western World on the probability of
income tax adoption. As common in the literature, we use concentration of land ownership
as proxy of the bargaining power of landed elites (Ansell and Samuels, 2015; Boix, 2003;
Ziblatt, 2008). Higher levels of landholding inequality were likely to enhance the probability
of adoption of the new tax, by giving landowners a higher ability to design a new tax that
imposed new fiscal burdens on the manufacturing sector. We test this proposition twofold:
cross-nationally, using a sample of 17 developed economies; and using micro-historical data,
by modeling the economic and political determinants of the vote to adopt the Income Tax
Act in the United Kingdom in 1842.
The second set of factors explaining the considerations of incumbent elites in non-
democratic settings to adopt income taxes were political in nature. Early nineteenth century
electoral rules in the Western World included a variety of provisions that used payment of
direct taxes to exclude individuals from political participation. In many early adopters, pre-
existing electoral laws conditioned voting rights on direct tax payments. These pre-existing
4
electoral provisions were an institutional mechanism that reinforced inequality in political
participation. In these countries, incumbent elites recognized that the income tax could be
layered on pre-existing electoral rules and reconfigured at times of elections as a wedge that
excluded low-income voters from parliamentary participation.
We explore the consequences of an extended restrictive electoral institution that was in
place in nineteenth century Europe prior to the adoption of universal suffrage: the vote-tax
link. This electoral provision considered payment of direct taxes as a necessary criterion
to grant electoral rights. We explore how this electoral rule that linked tax payments to
political rights modified the calculations of political insiders about the desirability of a new
income tax. In countries with a vote-tax link, the new income tax could be reconfigured
as a barrier preventing the political participation of poor voters who did not pay this tax.
These advantages of this restrictive electoral for political insiders could be shared by all high-
income voters, irrespective of their asset-ownership. As such, these considerations created
opportunities for a political alliance in support of an income class among owners of fixed
and mobile assets whose economic considerations about the adoption of the new income tax
could differ. We claim that considerations about these possible political gains prevented the
emergence of a frontal opposition of manufacturing elites to a tax which was economically
disadvantageous to this sector. To test this argument, we examine empirically the relation-
ship between vote-tax link and the probability of income tax adoption. Consistent with our
hypothesis, we find that the vote-tax link increases the probability of income tax adoption
under non-democratic settings.
Our paper contributes to the literature that examines the origin and development of fiscal
institutions in several important ways. First, to account for the puzzling adoption of the
income tax in non-democratic settings Aidt and Jensen (2009), we formulate a new micro-
logic that accounts for the motifs of elites in countries with restrictive suffrage to support
the development of extractive fiscal institutions. Our explanation stresses the importance
of inter-sectoral competition among landed and manufacturing elites over the allocation of
5
the tax burden, and considerations about likely gains in terms of political representation
associated with the adoption of the new tax. Our sectoral model stressing elite competition
dovetails with other recent work on democratization and redistribution, such as work by
Ansell and Samuels (2015), but diverges from models by Acemoglu and Robinson (2000)
and Boix (2003), which posit the existence of strong opposition of landed elites to new forms
of taxation and redistribution. We also show that the political conflict at the time of income
tax adoption was primarily a conflict along sectoral lines that differed from later class-based
conflicts over the progressivity of the tax system. While the most divisive political issues at
the time of income tax adoption concerned horizontal redistribution across sectors, the most
significant political conflict around World War I concerned vertical redistribution between
high and low income earners as well as issues concerning the fairness in the distribution of
the burden of war (Scheve and Stasavage, 2010).
To develop and test these arguments, the remaining part of the paper will be organized as
follows. We begin with a descriptive exploration of cross-national patterns in the adoption
of income taxes in the Western World. We then formulate a number of arguments that
seek to identify the economic and political considerations of political elites in countries with
restrictive suffrage about the desirability of income tax adoption. We first present a number
of hypotheses about the economic considerations of the owners of different assets with respect
to the advantages of the new income taxes. Next, we explore how different electoral rules
modified these economic calculations. Following the cross-national tests, we turn to the
analysis of one case to further test our theoretical hypotheses. We examine the adoption
of the Income Tax in Great Britain in 1842, by documenting the Parliamentary discussions
that preceded the adoption of this legislation and by modeling the determinants of support
of the new tax. Our roll-call vote analysis examines the relationship between district-level
economic conditions, biographic characteristics and partisanship of MPs on parliamentary
support for the new legislation. We conclude by offering evidence of the tax incidence of the
income tax across sectors. Some final remarks follow.

2 The Adoption of the Income Tax
Beginning with the first two decades of the nineteenth century, governments began to
take on an increased number of obligations, which included investment in the development
of infrastructure, the improvement in the provision of public health and the expansion of
the provision for education (Lindert, 2004). To finance these new responsibilities, politicians
sought to find ways to diversify the sources of revenue that could be enlisted for tax purposes.
The list of possible sources for fiscal revenue considered at the time was, from a contemporary
perspective, heterogeneous. Possible taxes that were under consideration at the time included
taxes on windows and buildings, taxes on luxuries, taxes on matches, taxes on business and
so on. Nevertheless, proposals to impose taxes on income were only one among the many
alternatives that was regarded as a source of possible tax revenue.
Recommendations to adopt a tax on income met with strong skepticism and opposition
(Daunton, 2001). Opponents of the new tax invoked both political and administrative dif-
ficulties associated with its implementation. First, considerable difficulties existed about
ways in which “income”, the new category that was at the basis of the new tax, could be
ascertained and what its different components that could be assessed for tax purposes should
be. Considerable uncertainty existed as to whether the different sources of income were to
be taxed separately, in separate schedules, or whether they were to be taxed jointly. Coun-
tries that pioneered income tax adoption chose very different solutions to this question, with
Prussia and Britain establishing the two possible extremes with respect to the technology of
taxation of the new income tax. In Britain, all different components of income were taxed
in different schedules in an effort to strengthen the monitoring capacity of the state (Mus-
grave, 1969). Prussia, by contrast adopted what was known as a “synthetic” income tax
which required all taxpayers to sum up their disparate sources of revenues for tax purposes
(Popitz, 1926). Given the difficulties in defining income, the unit of the new tax, consider-
able uncertainty existed about the designation of the authority that had the responsibility
to verify the tax obligations of different individuals (Daunton, 2001). Finally critics of the
7
new tax objected that the incentives of individuals to comply with the new tax obligations
would be very low.
By invoking a combination of these arguments, in some countries opponents of the new
tax succeeded in blocking its adoption. In other countries, proponents of the new income tax
triumphed against considerable political opposition. Examples of the latter are conservative
Prime Minister Robert Peel who succeeded in forging a political coalition in favor of an
income tax, or Robert Miquel, the architect of the Prussian income tax who engineered
a political coalition in favor of the new tax. Miquel’s proposal for an income tax was
adopted with a considerable political majority of 322 votes in the Prussian lower house,
with only 40 deputies opposing the law. Support for the new tax came from Conservatives,
National Liberals and Free Conservatives, three of the largest political parties on the right.
Similarly, Peel built an overarching conservative majority to adopt the new income tax in
1842. Appealing to the “superior goal” of fiscal responsibility, Peel reintroduced the income
tax in Britain with 97.5 percent favorable conservative vote.
The Prussian and British experiences were not exceptional. Figure 1 presents descrip-
tive information about the timing of the adoption of income taxes across seventeen Western
economies during the period between 1842 —the year when Britain introduced the first per-
manent income tax—and 1939, the year when Switzerland introduced a permanent income
tax at the federal level. The horizontal axis in each graph displays time. The vertical axis
represents the scope of suffrage. For each country, the solid line presents year-to-year infor-
mation on the scope of suffrage. The vertical dashed line indicates the year of the permanent
adoption date of the income tax.2

The descriptive information presented in Figure 1 reveals a number of surprising patterns
concerning the relationship between the adoption of income taxes and democratization. First

and surprisingly, we find that a significant number of countries adopted the income tax at
a time of very restrictive suffrage. These countries include Britain, which pioneered the
modern income tax in 1842, Austria (1849), Italy (1864), Japan (1887), Norway (1892),
Netherlands (1893), and Sweden (1902). In Britain, the earliest adopter, only 13 percent
of the population was eligible to vote in 1842. In Austria-Hungary, the immediate follower,
curia representation, which guaranteed disproportioned political leverage to the landed elites,
was still in place. In Italy, only 8 percent of adult population was entitled to vote in 1864, the
year when income tax was adopted. By contrast, countries that had established extensive
suffrage rules early on during the period of democratization delayed the adoption of income
taxes by several decades.3 In France proposals to adopt income taxes that were advanced on
repeated occasions during the 19th century encountered political opposition, and an income
tax was adopted only in 1911. These descriptive patterns suggest that early democratizers
faced more difficulty in reaching a political consensus about the new tax.
How effective were these early taxes in raising fiscal revenue? Were these early income
taxes just scraps of paper adopted for purely ceremonial purposes alone? To examine these
questions, we explore the consequences of the adoption of income taxes on direct tax revenue.
If income taxes were purely ceremonial, we should see no relationship between income taxes
and the level of fiscal revenue.
Figure 2 Here
Figure 2 plots the evolution of direct taxation as a share of central government revenue
for the early adopters in Western Europe: the United Kingdom, Austria-Hungary, Italy,
Norway, Netherlands and Sweden. All these six countries adopted the income tax under
very restrictive conditions of franchise. Certainly, the initial tax rates adopted were low
for modern standards. The top rates never exceeded 5% (Kennan, 1910; Popitz, 1926).
Yet these taxes were progressive from the very beginning, imposing a higher burden on

higher income individuals, who were very remarkably concentrated at the time. To get a
better understanding of their fiscal impact, we plot the total evolution of direct taxation 15
years before and 15 years after the adoption of the income tax. Year 0 denotes the year in
which the income tax was adopted by each country. Figure 2 suggests the existence of a
structural break in direct taxation revenue of approximately 7 points precisely at the year of
adoption. Certainly, the effect we observe in Figure 2 is not trivial, and poses the question
of why this tax was adopted in the first place.4 To solve this question we need to unravel
why a consensus about the adoption in income taxes and investment in the development
of fiscal capacity emerged in some countries, but not in others. Next, we formulate two
complementary hypotheses that account for the adoption of income taxes under conditions
of limited political suffrage.
Our first hypothesis is that the adoption of the income tax results from a political bargain
in which owners of different assets attempt to minimize their own tax burden, while shifting
a higher burden of taxation onto the competing sector. This is, in essence, an argument of
inter-sectoral redistribution through taxation. Specifically, we conjecture that in economic
conditions that increased the bargaining power of landed elites (or old elites), owners of fixed
assets were more successful in imposing the new tax on owners of mobile assets (urban elites
or new elites). One such factor that increased the bargaining power of landed elites is the
level of landholding inequality. Our second hypothesis is that the calculations of political
elites about the desirability of the new tax were influenced by pre-existing electoral rules.
Some of the electoral provisions that were in place in the countries with limited suffrage
conditioned political participation on payment of direct taxes. The adoption of income
taxes and its addition to the menu of existing direct taxes had the potential to increase the
4We do not have comparable data for Japan and New Zealand, also early adopters. For these countries,we only have post-adoption data. However, these suggest that the early income taxes in both countries werealso consequential. In 1890 Japan, five years after the income tax was adopted, this tax represented 2.3% ofdirect taxation (Ranis, 1959). This number grew to 10.7% only ten years later (ibid.). Actually, if we countthe corporate tax as an income tax (as it was in the UK), these figures are 3% and 22.6%, respectively. InNew Zealand, the income tax represented 17.6% of total direct taxation only two years after its adoption(Statistics New Zealand, 1893). These figures suggest that the income tax was neither scraps of paper amongits early adopters outside Europe.

existing inequalities of political representation, by linking electoral rights to the payment
of taxes. Incumbent elites (either landed or urban) elected under these restrictive electoral
rules recognized the political advantages of a new tax that could raise the barriers to political
participation of low income voters, and, accordingly, supported its adoption.
2.1 Economic considerations for income tax adoption: sectoral
incidence
Prior to the adoption of the income taxes, governments relied on very heterogenous taxes
to collect the fiscal revenue that was necessary for the financing of public and military
expenditures. These taxes included poll taxes, property taxes, and a variety of consumption
taxes (Popitz, 1926; Seligman, 1911). The income tax promised to bring two changes to
this policy landscape. The first innovation was that of uniformity. The income tax sought
to replace a variety of different sources of revenue with one single category: income. The
income tax also carried the promise of bringing in higher levels of fiscal revenues, by enlisting
resources that had previously evaded tax authorities. These previously untaxed resources
were distributed unequally across sectors. Precisely this unevenness in the location of the
source of the new tax revenue became a source of distributional conflict at the time of income
tax adoption.
Two questions were at the center of the inter-sectoral conflict. The first was the desir-
ability of the taxation of income, as compared to the taxation of other sources of revenue.
The second question concerned the inter-sectoral allocation of the tax burden (i.e. the in-
cidence of taxation), which was particularly relevant in a period of major economic change
associated with the industrialization of Western economies. We hypothesize that owners of
fixed assets considered the taxation of income as a much more attractive fiscal instrument
as compared to owners of mobile assets. First, owners of fixed assets favored the reliance on
income as the category that defined the tax liability of the individuals. That allowed fiscal
authorities to draw on and enlist new sources of revenue, such as profits, that had previ-
11
ously escaped taxation and that were more likely to be found in the newly rising industrial
sector. A brief examination of the provisions of income taxes adopted by these countries
lend support to the economic hypothesis. The 1842 income tax adopted in Britain did not
tax capital gains, not even from real estate, whose major owners were landowners, but did
levy income stemming from trade, thus targeting the new industrial elites (Daunton, 2001,
pag.205). The income tax adopted by Austria in 1849 also exempted land and buildings,
but imposed a rather progressive rate of taxation on profits and other professional incomes.
The latter tax rate rose to 20% during the first years of existence of the new tax (Kennan,
1910; Seligman, 1911). The Italian income tax adopted in 1864 did not tax incomes derived
from the ownership of land, but taxed profits and capital investments.
Secondly, owners of fixed assets also hoped that the introduction of the new income tax
would relief taxation of other assets, such as land. By contrast, owners of mobile assets were
more likely to express worries and concerns about the desirability of the introduction of a
new tax on income. The income tax would not only target profits (previously untaxed) but
also make manufacturing products more expensive in a context of increasing international
competition. Accordingly, owners of mobile capital were likely to oppose the new income
tax.5
Importantly, considerations about capital flight might account the lower tax rates that
we find in the initial income taxes. Concerns about capital flight were raised in numerous
occasions in the debates that preceded the income tax act in Westminster. “Let them harass
the manufacturer by taking and taking by an inquisitorial and offensive process by taking a
portion of those profits [...], he would probably transfer to other lands those pursuits which
they apparently contemplated with such strong disapprobation. [...] The wealthy capitalist
the skillful operative might quit their shores” (Sir W. Clay, merchant and Whig MP for
Tower Hamlets, HC Debate March 21, 1842). We interpret the risk of capital flight as an
5The economic hypothesis is consistent with Bates and Donald Lien (1985) seminal work, which alsodiscuses economic losses incurred by owners of fixed capital as a result of the increase in the importance ofmobile capital owners. Precisely, we claim that the income tax helped fixed-capital owners to rebalance theireconomic and political power vis-a-vis the new industrialists.
12
upper bound to the tax rates that the landed elites could impose the new sectors. External
constraints, however, should not prevent landed elites from levying tax rates on capital above
those on land whenever they are powerful enough, as the experience in Imperial Germany
suggests (Hallerberg, 1996).
This first hypothesis postulates the existence of sectoral conflict between landed and in-
dustrial elites over the adoption of the new income tax, much in line with the logic of sectoral
competition proposed by Ansell and Samuels (2015). Economic conditions are likely to af-
fect the relative bargaining power of owners of different assets and increase the probability
of income tax adoption. One such economic condition is the level of land inequality. Higher
levels of landholding inequality were more conducive to the selection of wealthier, conserva-
tive politicians (usually the landowner of the respective district) who were supportive the
adoption of the new tax with visible economic and political advantages. By contrast, we
expect to find delays in the adoption of the income tax in countries with lower levels of
income inequality, due to a lower bargaining power of landed elites in these contexts.
Note that our theoretical hypothesis about the effect of rural inequality about the ability
of elites to reach compromises about the new income tax is the opposite of the prediction in
the existing literature (Sokoloff and Zolt, 2007). In our account, rural inequality, everything
else constant, is expected to have a positive effect on the probability of income tax adoption.
This hypothesis is consistent with Hallerberg’s analysis of tax competition in the Wilhelmine
Germany, 1871-1914 (Hallerberg, 1996). Hallerberg documents how German states with
limited suffrage and strong landed elites in Parliament —with Prussia as the paradigmatic
case—were successful in shifting the incidence of direct taxation onto mobile capital owners.6
By contrast, states with more open franchises and a weaker representation of landed elites
in Parliament (such as Baden) increased the tax rate on mobile capital and labor together
with the land tax.7
6See also Hallerberg (2002) for a case-specific analysis.7It could be argued that industrial elites could pass on the burden of taxation to consumers by raising
intermediate or final good prices. For our argument to hold, we only need that the incidence to fall even ifonly partially on the modern sector, whose rents had gone virtually untapped under the old fiscal system.

2.2 Political considerations for income tax adoption: the effects
of electoral institutions
In many Western countries, political negotiations about the adoption of the income tax
took place in an environment characterized by restrictive electoral rules. Many of the elec-
toral systems that were in place in nineteenth century Western World used criteria such
as the wealth of different individuals or the payment of taxes to allocate electoral rights.
An important issue facing politicians that adopted the income tax was whether the new
law could enhance the existing electoral rights of incumbent elites, given existing electoral
rules. In this section, we consider these additional calculations about the political effects of
the income tax. Specifically, we assess the political calculations of incumbent elites in the
presence of a restrictive electoral rules that were in place at the time: the vote-tax link.
We define the vote tax link as an electoral provision that used payment of direct taxes
to reduce political participation of lower-income individuals. Specifically, the vote-tax link
is an electoral institution that conditions the right to vote on the prompt payment of direct
taxes. The vote-tax link was widely used in Europe, but also in the United States and Japan,
as listed in Table 1. All these countries, at one point, conditioned franchise for the national
elections on direct tax payments.8
Table 1 here
The existence of the vote-tax link establishes a convenient political tool for incumbent
political elites to restrict political participation. This electoral institution offered a tech-
nology that could be easily reconfigured as a tool of political exclusion once the new tax
was in place. The vote-tax link created two distinct opportunities of political exclusion of
That is, partial incidence suffices to make the adoption of the income tax in the interest of landed elites. Thestrong opposition to the income tax of the British MPs representing the industrial interest (further detailsbelow) suggests the passing the incidence of taxation entirely onto consumers was virtually impossible. Weare grateful to an anonymous reviewer for pointing out this necessary condition for our argument to hold.
8Table A-2 in the Online Appendix supplements this information by indicating in which countries thevote-tax link was actually effective when the income tax was adopted.
14
lower-income individuals. On the one hand, as the vote-tax link made the cost of political
participation visible, it was also likely to discourage demands of low-income voters for the a
further expansion of suffrage. On the other hand, the pecuniary cost of political participa-
tion was likely to depress the participation rates of the poorer strata among those qualified
to vote (i.e. the urban middle classes). With respect to fiscal outcomes, the vote-tax link
was seen as a guarantee of fiscal conservatism, which was widely embraced by elites during
the second half of the nineteenth century in the Western World. At the time, it was believed
that voters would refrain from demanding high expenditure programs (and thus, high taxes)
only if they were to fund these programs out of their own pockets (Daunton, 2001; Aidt,
Daunton and Dutta, 2010). Under that belief, a linkage between voting rights and income
taxation was seen as a natural mechanism to prevent overspending.9 In the words of William
Gladstone: “it is desirable in a high degree, when it can be effected, to connect the posses-
sion of the franchise with the payment of taxes”.10 For all these reasons, we expect that the
pre-existence of electoral rules that link tax payments to electoral participation should cre-
ate political conditions that facilitate the adoption of the income tax in a proto-democratic
setting.
Table 2
Table 2 summarizes our hypotheses about the desirability of an income tax in countries
with restrictive suffrage. These hypotheses present several plausible micro-logics that may
explain the early adoption of income taxes by non-democracies. We have identified the
economic and political considerations of owners of fixed and mobile assets, respectively.
With respect to economic gains, we have hypothesized that owners of fixed assets are more
likely to gain from the adoption of an income tax than owners of mobile assets. We have also
hypothesized that pre-existing electoral rules may offer political advantages to insiders once
the new income tax is adopted. By amplifying inequalities in representation, a new income

tax is likely to reinforce and enhance political advantages of incumbent elites. In this regard,
we expect that both owners of fixed and mobile assets should benefit from the adoption of
income tax in presence of this very particular electoral provision, the vote-tax link.11 These
common political gains might forge an informal alliance among elites from different sectors
who otherwise may disagree about the economic consequences of the new tax.12
3 A test of the economic and political gains of income
tax adoption
Next, we test for the economic and political gains hypotheses in modeling the adoption
of permanent income taxes in the Western World.13 We follow (Aidt and Jensen, 2009) and
establish the defeat of Napoleon in 1815 as the starting point of the analysis. The Napoleonic
Wars propelled the adoption of income taxes in various countries of the European continent:
the United Kingdom and France, but also the Austrian Empire, Belgium, Denmark, the
Netherlands, and Norway. After Napoleon’s defeat, the income tax was eliminated every-
where, but the precedent (that is, the technology) and the risk of its permanent adoption
11 Notice that industrial elites had to experience some gain from the new tax to secure quasi-voluntarycompliance, as it had been procured in 1799 when the income tax was temporary adopted in the UK towage the Napoleonic wars (Levi, 1988). An income tax would have been just too hard to administer withthe frontal opposition of the industrial elite.
12The vote-tax link is conceivable not the only electoral provision that might give a political advantage tothe incumbent elites. Electoral provisions that assign voters to different tiers in Parliament based on theirtax payments might do as well. This is the case of Prussia and other German principalities between 1871 and1913, where tax payments led to huge parliamentary malapportionment and facilitated the early adoptionof the income tax. Nevertheless, tax-based parliamentary malapportionment is an electoral provision thatis relatively rare in national parliaments in the Western World: Austria-Hungary had an estate-parliamentthat reserved one of the four (later five) curiae to big tax payers. Yet, the curia system was adopted in1861, only after the income tax had been adopted in 1849. Finland had a curia system similar to that inAustria-Hungary, but it was in place only during the period when Finland was under Russian control. Basedon the income tax adoption years, milder versions of tax-based malapportionment, such as the “plural vote”in Belgium and France, by which high tax payers receive a few additional votes, might not provide the sameclear incentives to the ruling elites.

The structure of the data is Binary Time Series Cross Sectional (BTSCS). Beck, Katz
and Tucker (1998) prove the virtual equivalence between BTSCS and survival models. As
such, the adoption of income tax can be fitted with a standard logistic regression. We only
need to add a time trend of the years at risk of adopting the new tax to account for the
conditional hazard rate. For that purpose, we follow Carter and Signorino and fit a cubic
polynomial approximation to account for duration dependence (Carter and Signorino, 2010).
The Online Appendix includes a replication of the analysis using frailty models that allow for
unit-specific hazard rates, splines instead of flexible polynomials (Beck, Katz and Tucker,
1998), and complementary log-log models that do not assume ex ante any shape of the
hazard rate. The exact model specification is as follows.15
P (yit = 1|xit, yit−1 = 0) =1
1 + e−(xitβ+H(t−ti))(1)
Expression (1) models the adoption of permanent income tax y by country i at time t
(provided it has not been adopted yet) as a function of time-variant covariates xit and a
smooth function of the number of years a country has been at risk of adopting the income
tax: H(t− ti) = t+ t2 + t3, where t denotes the time elapsed since the observation enters the
sample. By expression (1), once a given unit adopts the income tax, it drops the sample.
Table 3 here
We begin the cross-national analysis by replicating Aidt and Jensen’s (2009) “suprising”
finding: namely, countries with limited franchise and proto-democratic institutions, proxied
by the Polity IV (Marshall and Jaggers, 2000), pioneered the adoption of the income tax. The
effects are robust to the inclusion of standard socio-economic covariates, a Europe fixed effect
14For those countries that were not independent in 1815, we assume that they only become at risk assoon as they gained independence. Again, we follow Aidt and Jensen’s (2009) approach.

that accounts for unobserved idiosyncrasies of the Old Continent, and, more importantly,
the usual suspect of any major innovation: i.e. war (Dincecco, 2011; Tilly, 1990).16
The remaining models in Table 3 and 4 seek to shed light on this counter-intuitive result
by examining the political and economic determinants of the adoption of income taxes. The
models reported in columns 2 to 5 in Table 3 assess the economic gain hypotheses, which
conjectures that politicians with ties to owners of fixed factors should be more supportive of
the adoption of an income tax as compared to politicians representing mobile assets. As the
income tax taxed income that was previously undetected, it imposed a higher burden on the
owners of mobile assets as compared to owners of fixed assets. Secondly we have argued that
expectations of future changes in the balance of power among owners of fixed and owners of
mobile assets are likely to affect their relative preferences about the desirability of the new
income tax. Particularly, we conjecture that in a time of major economic change landed elites
in limited democracies favored the adoption of income taxes because the incidence of this
tax fell mainly on the new urban elites. The income tax was, in other words, a mechanism
of redistribution of the tax incidence across sectors.
The observable implication of the economic gain hypothesis is that economic and political
factors that strengthen the relative bargaining power of owners of fixed assets are likely to
increase the probability of income tax adoption. We follow the empirical strategy in the
literature on democratization and proxy the economic power of landowning elites using
a measure of land concentration (Ansell and Samuels, 2015; Boix, 2003; Ziblatt, 2008):
specifically, we use the share of farms owned by families, as constructed by Vanhanen (2003)
from the agricultural censuses.17 We expect a positive relationship between this variable
16Refer to the Online Appendix for further specifications and measures of war-related activity.17Vanhanen (2003) offers decennial values of land ownership concentration. To impute in-between years,
we pursue flat-steep-flat coding. That is, we assign the last available value in the series to all subsequentobservations for which data is missing. Suppose that we have family farm information for 1900, 1910, and1920. From 1901 to 1909, we set family farm equal to its value in 1900, and from 1911 to 1919, we setfamily farm equal to the 1910’s record. Additionally, if the first observation for family farm follows thefirst observation for franchise, the first available value of family farm is extrapolated toward the past. Forinstance, if the first records of family farm and franchise for a given country are 1850 and 1820, respectively,family farm between 1820 and 1850 is set to its value in 1850.

and adoption of the income tax. The model reported in column 2 tests and confirms this
proposition. We find that countries with high levels of Landholding Inequality are more
likely to adopt the income tax.
One might argue that a broad range of factors proxying economic development, such as
the GDP per capita, population, or the level of urbanization, “the forces of development”
(Aidt and Jensen, 2009, pag.166), may affect the ability of a given country to adopt the
income tax as a permanent tax. Similarly, the prior experience with income taxation (either
as a temporary national level tax or as a local level tax), or the availability of other sources
of revenue may affect the probability of the adoption of a permanent income tax. Thus, one
conjecture is that the previous experience with income taxation at the national or local level
may facilitate the permanent adoption of this tax,18 whereas the presence of alternatives
sources of revenue may slow down the adoption of the income tax. All models control for
the former battery of factors, while column 3 specifically evaluates alternative sources of
revenue by assessing the relationship between tariffs and the adoption of income taxes. Here
we use Ad-Valorem Equivalent (AVE) tariffs (Lampe and Sharp, 2013), which are calculated
as the ratio of customs duty revenue to total imports for domestic consumption.19 We might
expect that when AVE tariffs are high enough, there might be no fiscal justification to adopt
an income tax. This variable holds a positive, yet not significant coefficient, contradicting
the hypothesis that higher levels of tariffs substituted for the need of countries to adopt
income taxes. This result is, however, not surprising to someone familiar with fiscal policy
development in the early nineteenth century. At the time, the income tax was not understood
as being a substitute, but as a complement of trade taxes, as the incidence of both taxes
fell on the trading sectors (Daunton, 2001, pag.83). Importantly for the economic gain
18Population and GDP per Capita (Aidt and Jensen, 2009) are linearly interpolated as to maximize thesimple size. Urbanization (Vanhanen, 2003) is interpolated following the flat-steep-flat strategy described inft. 17, as we use it to compute Rural Inequality, explained below. Data for local and temporary nationalincome taxes are drawn from Aidt and Jensen (2009).

hypothesis, Landholding Inequality keeps a positive sign and remains statistically significant
when we control for this alternative source of revenue.
Columns 4 and 5 repeat the same analyses using the measure of land inequality pro-
posed by Ansell and Samuels (2015): Rural Inequality. These scholars suggest adjusting
Vanhanen’s “family farms” for the actual density of rural population. “There is a possi-
bility that, even in countries where families own most of the cultivable land, most of the
rural population might not live on a family farm” (Ansell and Samuels, 2015, pag.101). To
properly measure overall inequality of agricultural landholding, they recommend to adjust
the measure of Family Farms by the size of the rural population, thus calculating “Rural
Inequality” as (1-Family Farms)(1-Urbanization)/100, where Urbanization, also taken from
Vanhanen (2003), is the percentage of urban inhabitants (ibid.).20 The relationship between
this variable and the probability of income tax adoption is similar to Landholding Inequal-
ity. The coefficient for Rural Inequality is positive and highly statistically significant in both
models reported in columns 4 and 5. The smaller magnitude of this coefficient is just a
byproduct of the wider range of this variable, which increases by two orders of magnitude.
Altogether, the results in Table 3, advance evidence consistent with the economic gains
hypothesis while confirming the surprising pattern identified by Aidt and Jensen. We in-
terpret these findings as suggesting that in conditions of restrictive political suffrage higher
rural inequality increased the ability of landholding elites to adopt the income tax to shift
the burden of taxation to the rising trading sector.
Next, we evaluate the political gains hypothesis, which conjectured that the calculations
of owners of different types of assets about the desirability of the income tax were affected
by an electoral institution linking individual voting rights to prompt tax payments, or the
vote-tax link. Specifically, we expect to find a positive relationship between this electoral
provision and the adoption of the income tax. Politicians elected under this type of pre-

20
existing electoral rule are likely to regard the new income tax as a policy instrument that
maintains and reinforces their political advantage. Table 1 in the previous section reports
the countries and years in which the vote-tax link was in place in the countries included in
our analysis.
Table 4
The models in Table 4 build on the specifications presented in Table 3 and include controls
for socio-economic conditions, political institutions, warfare, and, importantly, landholding
inequality. The results reported in column 1 indicate that the existence of institutions
linking tax-payments to political participation facilitated the adoption of the income tax.
The coefficient is positive and statistically significant at 95%. In words, countries with pre-
existing electoral provisions conditioning the right to vote on the prompt payment of direct
taxes were more likely to adopt the income tax. In column 2, we assess how robust the
vote-tax link is to the replacement of Landholding Inequality for Rural Inequality. Results
are virtually identical to those in column 1. That is, the vote-tax link positively predicts the
adoption of the income tax.21
Finally, we seek to examine whether the vote-tax link is robust to the consideration of
an electoral provisions that is associated with the old regime (Mares, 2015) and is argued to
predict the adoption of the income tax: the secret ballot (Aidt and Jensen, 2009).22 Column
3 of Table 4 confirms that the positive effect of the vote-tax link is robust to the presence of
secret ballot, whereas the latter’s is not statistically different from zero. This result confirms
the unique political advantage that the Vote-Tax Link offers to the ruling class: namely, it
can exacerbate inequalities in political representation by conditioning political rights on the
prompt payment of direct taxes. We claim that this political gain entered the calculations
of both landed and industrial elites in pushing for the adoption of the income tax.
21These and Table 3 results are robust to country-random effects as well as shared frailty (refer to OnlineAppendix). Importantly, the likelihood-ratio test for significant frailty is negative, suggesting that coefficientsare not biased by country-level unobservables.
22Secret Ballot is a time-varying indicator, and it is drawn from Aidt and Jensen (2009).

4 The British Income Tax Act of 1842
To further test our hypotheses, we examine the adoption of the permanent income tax
in Britain in 1842. In Britain, the proposal for the adoption of the new tax originated with
and was pushed through the parliamentary deliberations by the conservative government of
Robert Peel. The examination of this crucial case provides us with the opportunity to test
the micro-foundations of our argument. We will begin by examining the most important
issues that were contested during the political deliberations over the new tax through a
qualitative analysis of the parliamentary deliberations. Next, we will test our argument
about the determinants of political support of an income tax through a quantitative analysis
of the decisive vote in Westminster that led to the adoption of this tax. We will further
probe our argument, by examining the incidence of the tax burden on different sectors after
the adoption of the new tax.
During the parliamentary debates over the adoption of the income tax, both opponents
and supporters of the new income tax noted that the new technology of taxation, which
assessed income had the potential to raise higher revenue when compared to existing taxes.
Yet both critics and supporters of the new income tax argued that the close monitoring of
income —which was required by the new tax—was also inquisitorial in nature. The tax
was attacked as a “threat to personal liberty, for it would require inquisitions scattered
throughout the country to enquire into private affairs”(Daunton, 2001, pag.82). Lord Dal-
meny, a liberal politician considered that the new income tax was “an imposition of the most
grievous impost accompanied by the most odious processes of inquisitorial investigation that
can be inflicted on a free nation” (HC Debate March 18, 1842). Others noted that the new
methods of income assessment violated individual privacy, while several members of parlia-
ment doubted the good will and intentions of the tax assessors. As one MP argued, “spies
and informers must be set to work, and a pecuniary interest must be given to them in the
additional amount they procured to the Exchequer” (HC Debate April 4, 1842).
We find strong and systematic evidence of a political conflict between politicians rep-
22
resenting rural and industrial interests during the political deliberations over the adoption
of the new tax. Robert Peel himself admitted that the new tax affected owners of capital
severely. As Peel stated, “I admit that the tax may press with additional severity on account
of the uncertain future of profits on that property which is derived from trade” (HC Debate
March 18, 1842). Other liberal politicians opposing the new tax expressed similar reserva-
tions to the new income tax. The political intentions of the new income tax, these critics
argued, were to “seize the profits of trade, to submit it to the legalized persecution of the
tax-gatherer. It is to uphold the monopolies of the agriculturist and planter, that he calls on
us to wring the pittance from impoverished industry, and scatters a horde of officials over the
land to violate the sanctuaries of private life” (HC Debate March 21, 1842). Similarly, “It
was felt in commercial towns that it was unjust to tax the hard-earned produce of industry
on the same footing as the income of realized property, annually received without toil and
without risk. It is felt too that the real burden of the income-tax, a Government inquiry into
men’s private affairs, falls exclusively upon the trading classes” (italics added, HC Debate
April 13 1842).
A pervasive criticism of the income tax was that the tax imposed an unfair burden on
production and enterprise and that the incidence of the burden on different types of income
was unfair (Daunton, 2001, pag.83). Critics argued that “no tax could be devised which
could operate more unequally, more unjustly and more oppressively”. Opponents of the
new tax considered that it was unjust to impose the same tax burden on different forms of
income, as the latter originated through different processes. As liberal politicians argued,
imposing the same rate on “ ‘spontaneous’ income, on permanent property which could be
passed on from father to son and on precarious incomes based on personal exertion where
money had to be set aside to support dependents” was unjust. It was equally unjust to tax
“fluctuating income in the same proportion as permanent income” (HC Debate March 23,
1842). Yet liberals believed that the reasons for this inequality were political in nature and
that they could be attributed to the disproportionate influence of landed elites. “The reason
23
why the man of fluctuating income was severely taxed was, that the man of landed property
might escape taxation. The right hon. Baronet Peel did not dare to tax the landowner and
he therefore revenged himself upon the unhappy wretch who owned nothing but the faculty
of honestly earning high livelihood.”(HC Debate March 23, 1842).
In opposing the new income tax, members of parliament linked to Britain’s rising manu-
facturing sectors proposed several alternatives to the new tax. One set of proposals involved
scrapping the income tax altogether and replacing it with alternative taxes, while others
proposed changes to the income tax which lightened the burden of the new tax on the man-
ufacturing sector. Some of the proposals to augment the revenue-raising capacity of existing
taxes recommended the remission of duties on corn, the imposition of a legacy duty on
landed property or the increase in value of assessed taxes (HC Debate April 8, 1842; HC
Debate April 13, 1842). All alternatives to the income tax met however with defeat during
the deliberations. The remission of duties on corn, was rejected because it was believed that
such a tax could not generate the same level of income as compared with the income tax (HC
Debate April 13, 1842). Proposals to increase the level of assessed taxes, were also opposed
and eventually defeated on the grounds that these were even more burdensome as compared
to the income tax. “A great deal has been said about the inequality of an income-tax, but
the assessed taxes pressed with much greater inequality upon commerce and manufactures
than the income tax” (HC Debate April 13, 1842).
Alternative proposals made by Whig politicians recommended to lighten the tax burden
on the manufacturing sector within the income tax. This could be achieved either through
the imposition of different tax rates on funded or unfunded wealth or the exemption of various
incomes from the incidence of the new tax. Some of these proposals recommended to exempt
manufacturing interests altogether from the payment of the new tax (HC Debate April 29,
1842). Others recommended to exempt income derived from “alum mines, waterworks,
streams of water, canals, railways, bridges and ferries” from the payment of the new tax.
Finally, other proposals that were widely deliberated at the time recommended to impose
24
a lighter tax burden on incomes that were volatile, as compared fixed assets such as land.
Such proposals were, however defeated (HC Debate April 29, 1842). The argument that
eventually prevailed during the deliberations was that returns of land were as volatile as the
returns from commercial resources, making the differentiation of taxation for income from
volatile versus fixed assets unjust. As a result of the defeat of all these alternatives, Peel’s
income tax, a policy that was more favorable to the interests of landed elites was ultimately
adopted.
The marked division between politicians representing the interests of different sectors
was reflected in the final vote of the income tax, in May 31, 1842. Next we model the votes
of the different representatives as a function of partisanship, the background of the MP, and
the socio-economic characteristics of the districts that they represented. The results suggest
that, controlling for landholding inequality, district-level income and poverty, and the MPs
professions and social class, representatives of industrial districts opposed the income tax
while representatives of agricultural districts favored it.
4.1 A Roll Call Analysis of The 1842 Income Tax Bill
The parliamentary debates about the adoption of an income tax took place during a brief
period between March and May 1842. The third and last reading of the Income Tax was
held on May 31, 1842. 388 members of the parliament participated in this decisive roll call
votes, representing English, Welsh and Scottish constituencies. We collected biographical,
district and partisan information for these politicians (and were able to find this information
for 384 MPs). Our empirical analysis examines the relationship between these variables and
the vote for the income tax bill. We proceed stepwise. First, we evaluate the effect of district
characteristics, then biographical, and, lastly, partisanship.23
Table 5 here
23Among the early adopters, Great Britain is the only country that lacked a vote-tax link for its nationalelections. Such vote-tax link were, however, in place for local elections. Thus, in this section we only examinethe economic gain hypothesis explaining support for the new tax.
25
Table 5 reports the results of logistic models accounting for support or opposition to the
new income tax. The models reported in column 1 to 3 examine the relationship between
district levels characteristics and support for income tax, while including fixed effects for dif-
ferent regions (England, Wales and Scotland). Column 1 presents the simplest specification.
Here we regress the vote of MP on landholding inequality, controlling for the type of con-
stituency: urban vs. rural. Landholding inequality is computed as a Gini index of land size
at the county-level using the information of the first country-wide agricultural census in the
history of Great Britain, dated as of 1896, that we could locate (Agricultural Returns, 1896).
Using Vanhanen (2003) data, we can establish however that these values were closely corre-
lated to measures of landholding inequality in 1842, the year the income tax was adopted.
The national percentage of family farms in 1842 was 5%, and 8% only in 1890, suggesting
little change in the distribution of land between 1840s and 1890s (this share would reach
52% in 1975). Consistent with our hypothesis, the sign of this coefficient is positive. We
know that Conservatives were likely to be elected in rural districts while liberal MPs were
elected primarily in urban constituencies (Aydelotte, 1977, Table 7.1). Consistent with this
pattern, representatives of urban districts opposed the adoption of the income tax.
In column 2, we investigate the relationship between different economic characteristics of
districts and support for the income tax. Our variables include measures of population shares
of labor employed in agriculture, the old sector, and in retail, liberal professions (including
bankers), and manufacturing industry and industry, the new sector.24 The source for this
information is the 1831 UK Census, as coded by Southall, H.R. et al. (2004). Given that
this source covers England and Wales only, the number of observations in this and the next
column declines. We find that the higher the share of employment in the old-sector, the
more likely it is that a given representative will vote in favor of the income tax. In contrast,
a higher share of workers employed in new-sector activities correlates with a lower likelihood
that the representatives will support the income tax bill.
24Self-employed farmers are excluded, although results do not change when we include them
26
In column 3 we explore an alternative hypothesis, advanced by the literature on taxation
and democratization, which suggests that the income tax is adopted as a policy appeasing
the poor (Acemoglu and Robinson, 2000; Boix, 2003). To assess some of the implications
of these theories, we compute the district-level unemployment rate as well as the share
of individuals in houses rated under 10 pounds (Poor Homes) using information from the
1831 census. We also include a measure of population density, which we are using as a
district-level proxy of income25 One expectation of theories of democratization is that elites
in richer districts are more prone to support the adoption the income tax in an effort to offset
dramatic threats for expropriation. None of the three variables reach, however, statistical
significance at conventional levels. Fears of current or future redistribution do not seem
to explain the motives of support for the adoption of the income tax. Our alternative
explanation, premised on intra-sectoral competition among elites provides a better account
of the variation in political support for the new tax26
The models reported in columns 4 and 5 of Table 5 assess the relationship between
biographical characteristics of a legislator and their vote on the proposal to adopt the income
tax. Biographical information on legislators comes from the Aydelotte (1984) dataset, which
includes a wealth of political characteristics of all members of the British Parliament during
period 1841 to 1847. In column 4 we investigate whether MPs with a vested interest in
the business and financial sectors tend to oppose the income tax.27 The first coefficient is
negative and statistically significant, whereas the second is not statistically different from
zero. However, in subsequent models these effects reverse. We also tests for the relationship
between the aristocratic background of the MP and support for the income tax.28 This
25For a similar use of population density as proxy of income, see Acemoglu, Johnson and Robinson (2002)and Dincecco and Prado (2012).
26Likewise, proxies to district income such as population or population density, always hold positivecoefficients but never reach statistical significance.
27Aydelotte (1984) data includes a battery of items indicating whether MPs had invested in differenttypes of business.
28This variable has seven ordered categories: it takes value 0 for MPs that are unrelated to aristocracy.It takes value 1 for MPs whose family received a nobility title after 1837; value 2 for those who received atitle between 1820 and 1837; and successively until “before 1689”, the seventh category.
27
variable is positive but its statistical significance is not robust across different specifications.
The specifications reported in column 5 include a measure of the MP’s personal wealth.
This is a nine-category variable, ranging from $£2,000$ to $£1,000,000$. This variable
positively predicts the adoption of the income tax. This is consistent with the sectoral
redistribution of tax incidence, as landed elites were richest income group in 1842 Britain.
Finally, the results in columns 6 and 7 investigate the role of partisanship in predicting
the roll call. We use information reported in Aydelotte to construct this variable. Liberal
MPs opposed the income tax adoption (93% of them did). Not surprisingly, this variable
is strongly statistically significant in the expected direction. Importantly, inequality loses
statistical significance once we control for the partisanship of the MP. Due to the strong
alignment between district characteristics and partisanship, we interpret the change in the
coefficient of landholding inequality as an attenuation bias caused by controlling for a post-
treatment effect.
Political parties in the Peelite era were clearly defined. But the skeptical reader might
argue that partisan affiliations suffer from some rationalization of the coder (in this case,
Aydelotte 1984). To address this concern, the model reported in column 7 proxies policy
preferences with the voting record of the MP. To perform this test, we use Aydelotte’s
Guttman scale of the pro-land voting record. This scale is based on the behavior of each
MP in 9 different roll call votes affecting landed interests in the 1841-1847 session.29 This
scale tells us how strongly aligned each MP is with the interests of the landed sector. The
coefficient for this scale behaves as we would expect. The higher the alignment between the
politician and the interests of landed elites, the higher their support for the adoption of the
income tax.
To conclude our analysis of the British case, we investigate the incidence of the new tax
on different sectors during the years following its adoption. The British scheduled income
tax records the sources of various revenues collected by tax authorities, and it allows us
29For details, refer to the original Aydelotte (1984) codebook.
28
to calculate the fiscal pressure faced by each sector. Specifically, the 1842 income tax was
levied under five different schedules. Two of these schedules (A and B respectively) collected
income from the traditional sectors: income from land, real estate and agriculture. Schedule
D, by contrast, collected income from profit and liberal professions. During the decade of
the 1840s, 51.8% of total revenue came from schedules A and B, as compared to 29.4% from
schedule D (Parliamentary Papers, 1857). At first glance, one would see no harm done by the
new law to the industrial elite. However, over time the incidence of the tax was unfavorable
for industrial elites. Figure 3 presents the average tax rate for each of these two sectors for
the first 10 years of the law.
Figure 3 Here
In the first years following the adoption of the new tax, the value of assets in the tradi-
tional sectors doubled compared to the value of assets in the modern sector (Parliamentary
Papers, 1861). This explains why revenue stemming from land surpassed revenue from the
modern sector. However, keeping the value of the assets constant, the effective tax rate for
the modern sector was 30% larger than the rate on the traditional sector.30 Thus, from its
very inception, the incidence of the income tax fell more heavily on the modern sector. Even-
tually, total tax revenue from schedule D surpassed the total tax revenues from schedules
A and B. By 1907, the weight of income raised from schedules A and B accounted for 25.8
percent of the total tax revenues raised by the income tax. By contrast, total tax revenue
from schedule D accounted for 59 percent of tax revenue (Daunton, 2001, Table 7.2).
Altogether, our roll call vote analysis of the distributional conflict over the adoption of
the income tax and Britain’s subsequent experience with revenue collection with the new tax
30 The absolute values of the tax rate and their difference might seem marginal for modern standards.However, these rates were considered high by the time and caused heated debates in Parliament preciselybecause it tapped previously unknown income and had major distributive consequences. Interestingly, bylaw all sectors were required to pay the same tax rate: 7d in the pound on income of 150 l. and upwards (onaverage, that represented a 2.9% tax rate). In practice, the fine print usually benefited those individuals withan economic interest in the traditional sectors. For instance, when income arose under different schedules, theabatement was allowed preferably from the amounts reported in schedules D and E, as claimed by Kennan(1910). Landed elites, in essence, were exempted from paying taxes for their activity in the newer sectors.
29
lends support to the economic hypothesis of income tax adoption proposed in this paper.
Consistent with our expectation, we find that politicians closely aligned with owners of
fixed assets supported the adoption of the new income tax, while politicians representing
the interests of owners of mobile taxes opposed its introduction. The historical information
about the incidence of the tax burden on different sectors suggests that the income tax
generated more revenue from industrial sectors. As such, the operation of the new tax
conformed with the intended preferences of the owners of fixed assets: the income tax led
to fiscal rebalancing, by involving the industrial sector more heavily in the financing of the
public sector.
5 Conclusion
The adoption of the income tax has paved the way for a dramatic increase in the size
of government expenditures and represents a decisive turning point in the evolution of the
modern state. The political decision to assess taxes on income gave governments the means
to tap into a variety of revenues that had been hitherto not assessed. The adoption of
the income tax also went hand in hand with the development of additional institutions
that sought to assess income that originated from various sources and ensure compliance
of citizens with their tax obligations. This paper seeks to provide an explanation of this
decisive turning point in the development of the modern fiscal state.
Existing explanations stress the importance of war as factor accounting for the evolution
of the modern state (Dincecco, 2011; Scheve and Stasavage, 2010; Tilly, 1990). Our paper
reconfirms this long-standing result of the literature. However, wars and preparations for
armed military conflicts are not sufficient in explaining political decisions to adopt the income
tax. The calculations of political elites about the desirability of this radically new instrument
of revenue extraction were affected by domestic economic conditions, on the one hand, and
by existing electoral rules, on the other hand. We provide a set of hypotheses about the most
30
decisive economic and political factors that affected the considerations of politicians about
the desirability of the income tax adoption. We test these hypotheses, by examining the
variation in the timing of income tax adoption across the Western World during the period
between 1815 and 1939.
Our paper identifies two empirical regularities in the timing of income tax adoption across
Western countries during this period. We find that countries with high levels of inequality
and low levels of suffrage pioneered the adoption of the new income tax. These findings
challenge a widely held proposition which suggests that democratization spurs fiscal redis-
tribution. The theoretical expectations of standard models of taxation and redistribution
(Acemoglu and Robinson, 2000; Boix, 2003) do not hold in this important policy domain.
To account for these empirical regularities, we examine the calculations of higher income
individuals in countries with restrictive electoral rules about the desirability of the new tax.
We suggest that owners of fixed and mobile assets will have different expectations about
their future tax liability under the new income tax. While owners of fixed assets supported
the income tax because of the ability of the latter to roll off a higher tax burden on owners
of mobile assets, mobile asset holders were likely to resist the latter. Our empirical analysis
confirms this hypothesis, which posits the existence of a sectoral conflict over the adoption
of an income tax. We find that both structural and short-term economic factors that in-
crease the economic bargaining power of landed elites increased the probability of income
tax adoption.
In many of the early adopters of income taxation, political negotiations about the intro-
duction of a new income tax took place in environments characterized by restrictive electoral
rules. The electoral rules among these non-democratic countries varied significantly in their
institutional design. Our paper examines how a very specific type of electoral rule that was
in place in many European countries prior to the adoption of universal suffrage —the vote-
tax link—affected the calculations of incumbents about the desirability of the new income
tax. Consistent with our expectation, we find that the presence of a vote-tax link increased
31
the probability of income tax adoption in non-democracies.
As an additional test of some of the observable implications of our explanation, we have
collected micro historical evidence analyzing the adoption of the income tax in Great Britain
in 1842. Our quantitative analysis of the final roll call votes leading to the adoption of the new
income tax found that the adoption of the new tax was supported by conservative politicians
from districts with high level of landholding inequality, but opposed by politicians from more
urban interests. The analysis of the parliamentary debates in the British parliament that led
to the adoption of the new tax reveal the existence of a strong inter-sectoral conflict between
representatives of landed and manufacturing elites over the design of the new income tax.
Some of the most contested issue during these deliberations concerned the rates of taxation
of income from fixed or more mobile sources. We show that the fine-print of the final income
tax bill conformed to the intentions of conservative politicians to enlist resources from the
manufacturing sector for fiscal purposes and that alternative tax proposals advanced by
liberal politicians were defeated.
The findings in our paper open up interesting avenues of future research for the politics of
taxation and redistribution in non-democratic regimes, while emphasizing intra-elite compe-
tition as the ultimate cause of major fiscal innovations, much in line with Ansell and Samuels
(2015). Our findings suggest that existing models of redistribution operate with assumptions
about preferences for taxation that are too simplistic and that overlook important sources
of cleavages political incumbents in countries with limited electoral suffrage. We leave it to
future research to examine whether the surprising support of owners of high fixed assets for
policies with high redistributive potential such as the income tax can be also found in cases
of other policy areas.

Dropping Cases with minimum in Rural Inequality
The first values of family farms and urbanization for Finland, New Zealand, and Aus-
tralia in Vanhanen (2003) date as of 1918, 1908 and 1908, respectively. These values are
extrapolated until the date of independence for Australia and New Zealand, and 1815 for
Finland. This explains why the land inequality series for these countries are flat over the
period, even for Rural Inequality, for which temporal variation is supposed to be high due
to the rapid change in urbanization rates in this period. To ensure that the results are not
driven by these de facto fixed effects, Table A-4 reruns the main specifications upon drop-
ping these three countries from the sample. Results hold: high levels of Land and Rural
Inequality, as well as the Vote-Tax Link, predict the adoption of the income tax also in the
absence of Australia, New Zealand and Finland.

Replacing Germany for Prussia
In Table A-5 we replace Germany for Prussia. The former adopted the federal income tax
in 1920, after WWI. Prussia, as many other German principalities, adopted province-level
income taxes earlier, as soon as 1891, when franchise was restricted and a vote-tax link was
in place. Table A-5 replicates the main specifications replacing Germany for Prussia. Given
the size of Prussia, we use the Germany values for Land Inequality, War, WWI Participant,
ln(GDP/cap), and Urbanization. Aidt and Jensen (2009) franchise variable is defined as the
electorate (for parliamentary elections) in percentage of the enfranchised age and sex group,
before women’s suffrage, male population only. In Prussia, only men 20 years old or above
were allowed to vote. We draw the electorate size for Prussia from Wahlen in Deutschland
(http://www.wahlen-in-deutschland.de), and we approximate the share of male 20 years old
or above based on census data from the Preussische Statistik and Becker et al. (2014). Total
population is drawn from Flora, Kraus and Pfenning (1983). We set Temporary Income
Tax to 1 (Prussia adopted one during the Napoleonic wars), and Local Income tax to 0, as
Prussian municipalities had never operated this tax prior to 1891. Results suggest that both
Landholding and Rural Inequality, as well as the Vote-Tax Link, predict the adoption of the
income tax even if we replace Germany for Prussia.

Additional measures of War
Table 3 in the main text includes two controls for war: one is being at war at time
t, the other participating in WWI between 1914-1918. We included these two covariates to
investigate how robust the early adoption of the income tax among proto-democratic regimes
is once we control for the main cause of fiscal innovations (Dincecco, 2011; Tilly, 1990; Scheve
and Stasavage, 2010). Table A-6 considers additional measures of war. Columns 1 and 2
include the first and the second lag of war. The adoption the income tax might follow
war if the latter created debt that has to be honored once armed conflict is over (we do
not report models with additional lags as results do not vary). In column 4 we evaluate
whether participation in WWI has any lasting effect. WW1 Participant in the main text is
equal to one for WWI participants during war years and zero otherwise. WW1 Participant
(permanent) equals one for WW participants during war years and all that follow. That is,
it captures any lasting effect of participating in WWI. Finally, in column 5 we control for
the magnitude of commitments to and preparation for war efforts by including a measure
of military mobilization, measured by the share of military personnel to total population
(source: Singer, Bremer and Stuckey (1972)). Irrespective of how we adjust for the effect of
war on the adoption of income taxes, low franchise and low Polity IV are strong predictors
of the adoption of this tax, thus confirming the intuition in Figure 1.

Sequencing of land ownership and income tax adoption.
In two cases of the crossnational analysis, Japan and Belgium, the income tax is im-
mediately followed by a decrease in land ownership, proxied by Vanhanen’s (2003) family
farms. One might argue that this sequence is artificially induced by the decennial nature
of Vanhanen’s database, in which records are only offered on the eight year of the decade
(e.g. 1908, 1918, 1928). Based on the decennial structure, it could be the case that an
income tax, despite having been adopted after a land reform, appears as it preceded land
decentralization, thus reversing the true causal sequence. For instance, suppose that a land
reform in country x is passed in 1860. This would be reflected only in 1868 in Vahnanen’s
decennial data. Suppose now that the income tax in that country is adopted in 1865. If
we do not correct for the decennial coding schedule in Vanhanen, it would read as if the
income tax had been adopted before the land reform, not after. Based on Figures A-1 and
A-2, this issue could affect Belgium and Japan. How sensible are the results to Vanhanen’s
coding-induced sequencing? We examine this separately.
Japan. The income tax was adopted in Japan in 1887 as a part of the Meiji restoration,
which involved a bundle of political and economic reforms, among these, a land reform.
The latter started in 1873 with the adoption of Land Tax Reform, and it was completed
progressively during the 1870s and 1880s (Bird 1977).31 The effect of this reform is picked
in Vanhanen’s decennial data only in 1888. The previous data point, dated as of 1878, does
not account for any effect of the land reform. In particular, from 1873 to 1887 family farm
for Japan equals 0 (i.e. maximum landholding inequality). In light of Vanhanen’s coding de-
cision, one might suspect that the sequence of events in the dataset could bias the results in
our favor. To evaluate the possibility of bias, we can modify the rural inequality variable so
that it early recognizes the land liberalization under the Meiji’s reform. We do this twofold:
31Richard M. Bird. 1997. “Land Taxation and Economic Development: The Model of Meiji Japan”,Journal of Development Studies, Vol. 13(2): 162- 174.
xiii
first, we extrapolate the value of 1888 family farm entry (the first in the series that recognizes
the Meiji’s land reform) all the way back to 1873 (this is consistent with our flat-steep-flat
strategy, as explained in ft.17). Second, we linearly interpolate the value of land inequality
between 1873 and 1888. One way or another, after these changes are made, the land reform
is forced to precede the adoption of the income tax. We replicate the models in Table 3 in the
manuscript, using Rural Inequality as proxy for the bargaining power of the landed elites.
Columns 1-2 and 3-4 in Table A-7 report the results for the backwards extrapolation and
linear interpolation, respectively. Results are virtually identical to those reported in Table 3
even though, in column 3, Rural Inequality does not reach conventional levels of statistical
significance. All other variables behave as in Table 3. This is an important result, because
Japan constitutes a paradigm of the logic that we are advancing in this paper: that is, in
scenarios of limited representation, old-regime landed interests may benefit from the income
tax due to its economic and political gains.
Belgium. The income tax is adopted in 1922 in Belgium. Land Inequality, as measured
by the share of family farms, remains stable at 22% since 1858, except for the 1898-1917
period in which it decreases to 21% only to return to 22% in 1918. Then, this value jumps
to 30% in 1928.32 To confirm that the results are not driven by Vanhanen’s decennial cod-
ing (for instance, land could have been redistributed in 1919, 1920 or 1921 despite having
artificially remaining fixed to 21% until 1928), we replace all the post-1918 values of family
farm for the 1828 value: that is, 30%. This way, we assume that the reduction of land
inequality precedes the adoption of income taxes. Results with the revised coding of Rural
Inequality are reported in columns 5 and 6 in Table A-7. The coefficients for this variable
remain positive and statistically significant.
Overall, Table A-7 suggest that results in Table 3 are not driven by Vanhanen’s decennial
32We have not found evidence of any major land reform in Belgium right after WWI.

Accounting for unobserved heterogeneity
The models in the main text assume a common hazard rate for all countries, once we
control for all relevant covariates. However, we cannot guarantee that we have controlled for
every relevant variable. In an OLS framework, we would fit a country fixed effect to account
for unobserved heterogeneity that simultaneously influence the unit-specific baseline hazard
and the dependent variable. However, a full vector of country fixed effect cannot be fitted
to BTSCS data, as they would completely determine the duration of the subject. There is
still one option left to account for unit-specific heterogeneity: we can work with a Weibull
duration model with gamma heterogeneity (Beck and Katz, 2001, pag.491) an shared frailty
(Gutierrez, 2002), which accounts for unobserved unit heterogeneity in a similar fashion than
random effects models.
Specifically, frailty models add randomness to each units’ underlying propensity to adopt
the income tax as a function of explanatory variables combined with a stochastic term. This
kind of models are appropriate when we suspect that some units are more (less) likely to
adopt the income tax regardless of the values of the observed independent variables (Beck
and Katz, 2001). Shared frailty models are used when the unobserved frailty is shared
among groups of observations (i.e. the same country over time). Accordingly, the shared
frailty model is said to be equivalent to a random effect model for survival data (Gutierrez,
2002).
Shared frailty models are computationally demanding. Historical cross-national time-
series data, like the one we have here, is not best suited to run this complex models, as
variables tend to be slow moving, covariate correlations high, and left censoring to differ
between units. Still, in Table A-8 we report two set of stable models: one without the
covariates that we use to test our hypotheses, and one including all of them at once. Again,
they are estimated with a Weibull model with gamma heterogeneity and unit-specific (or
shared) frailty.
Results hold. That is, higher land or rural inequality, as well as the vote-tax link, predict
xvi
the adoption of the income tax when we adjust for unit-specific unobserved heterogeneity.
More importantly, the variance of the frailty, θ, is not statistically significant or is only at
10%. This implies that the unobserved unit effect that these models account for is small.
Accordingly, the common hazard rate that we assume in the main text seems is reasonable,
while making the estimation of the models less cumbersome.
For the sake of comprehensiveness, in Table A-9 we also fit splines models to account for
duration dependence (Beck, Katz and Tucker, 1998) and complement them with complimentary-
log log models (Carter and Signorino, 2010), which add full flexibility to the hazard rate by
not assuming ex ante any particular shape (i.e. increasing, decreasing, or non-monotonic).
Again, results hold.

Secret Ballot vs. the Vote-Tax Link
Aidt and Jensen (2009) find that the Secret Ballot is a strong predictor of the adoption
of the income tax. Table 4 indicates that the effect disappears when we control for the
vote-tax link. Here we run the same exercise but keeping Aidt and Jensen (2009) original
specification, which includes a squared term for Franchise, a control for Tax Technology (an
additive index of census, local tax, primary school enrollment, and a dummy variable for high
urbanization), and linguistic proximity between countries. Likewise, duration dependence
here is fitted with splines (Beck, Katz and Tucker, 1998). Results in column 1 confirm
Aidt and Jensen (2009) finding: the presence of the Secret Ballot increases the likelihood of
adoption of the income tax. Column 2 suggests that this effect vanishes once we control for
the Vote-Tax Link, which remains statistically significant. In other words, results in Table
4 are independent of specification.
