Automatic Tax Calculation Overview

If you enable the Automatic Tax Calculation feature, Payables will automatically calculate

invoice sales tax and create Tax type distributions for you. Payables automatically calculates

tax for manually entered invoices and recurring invoices. During Expense Report Import,

Payables also automatically calculates tax for invoices it creates. You enable the Automatic

Tax Calculation feature by enabling the Use Automatic Tax Calculation Payables option.

If you do not enable Automatic Tax Calculation, Payables does no tax calculation, but it will

automatically create a tax distribution during invoice entry if you enter values for Tax Code

and Tax Amount in the Invoices window. Payables copies the invoice tax code and tax

amount values you enter when it creates the tax distribution but it does no tax calculation.

However, it will validate the tax amount during Invoice Validation.

Automatic Tax Calculation Levels

If you use automatic tax calculation, Payables calculates tax for your invoices at the level you

specify, Header, Line, or Tax Code. The Calculation Level option you select determines

whether Payables calculates tax based on the invoice information (Header), or based on

individual invoice distribution information (Line and Tax Code). The difference between

Line and Tax Code calculation is how Payables groups amounts to calculate tax. The

difference in calculation is generally due to rounding differences. For a complete explanation,

see: Calculation of Tax Distributions For Line or Tax Code Automatic Tax Calculation.

The value of the Calculation Level option defaults in the following order: Payables Options

window -> Suppliers window -> Supplier Sites window -> invoice entry. (Note that you

cannot set a value at the Suppliers window if you use Multi-organization support). You can

override the Calculation Level at any level (supplier, supplier site, invoice entry) if the Allow

Calculation Level Override check box is enabled at the previous level. If you override the

calculation level you can change the calculation level to Header, Line, or Tax Code or you

can disable tax calculation by choosing None.

You choose the automatic tax calculation level in the Calculation Level fields of the Invoice

Tax regions of the Payables Options, Suppliers, and Suppliers Sites windows. If you have

enabled the Allow Calculation Level Override option at the supplier site you have one last

opportunity to change the tax calculation level when you enter the invoice.

You can use Header level calculation only if the tax code is fully recoverable. If the

transaction uses tax codes that are nonrecoverable or partially recoverable, you must choose

Line or Tax Code level calculation. See: Recoverable Tax.

Header

If you automatically calculate tax at the Header Level, then during invoice entry in the

Invoice Workbench, when you enter a tax group or Sales or User-defined type tax code in the

Invoices window, Payables automatically calculates and enters the Tax Amount. Payables

calculates the tax amount based on the gross invoice amount and the tax rate of the tax codes

you use. In the Tax Codes window you assign a tax rate to each tax code.

When you navigate to the Distributions window, Payables automatically creates a tax

distribution with the Tax Amount and Tax Code from the Invoices window. See: Header

Level Automatic Tax Calculation.

Payables does not calculate tax amounts for Use type tax codes.

Note: You cannot use Header level calculation in the Quick Invoices window or Expense

Reports window.

Note: Only fully (100%) recoverable tax codes can be used on the Header level. To define

recoverable tax codes, the Financials option Enable Recoverable Tax must be enabled.

Line

If you automatically calculate tax at the Line level, after you enter non-Tax (Item,

Miscellaneous, or Freight type) distributions in the Distributions window, Payables creates

Tax type distributions. When you enter distributions, you use the Includes Tax check box to

indicate if a distribution line amount is inclusive or exclusive of tax.

Payables calculates the tax amount for distributions based on the distribution amount, the

Includes Tax check box for the distribution, and the tax rate of the applicable tax codes.

If you use Recoverable Tax, the system also calculates tax based on the recovery rate. In the

Tax Codes window you assign a tax rate and recovery rate to each tax code. Payables creates

tax distributions for the appropriate amounts, and assigns the applicable tax code to each

corresponding distribution. If you enter a tax group, the system can calculate multiple taxes

for an invoice that contains both recoverable and nonrecoverable tax amounts and your totals

will reflect the appropriate tax distributions.

When Payables calculates tax for distributions that include tax, it also reduces the amount of

the Item distribution by the calculated tax amount and unchecks the Includes Tax check box.

Payables creates tax distributions automatically either when you choose the Calculate Tax

button in the Distributions window, or when you submit Invoice Validation for the invoice. If

the Enable Recoverable Tax option is enabled in the Financials Options window, then you

can also use the Tax Summary window to view and calculate the tax. Payables calculates tax

the same way for invoices entered via the Quick Invoices window and the Invoice

Workbench. See: Distribution Level (Line and Tax Code) Automatic Tax Calculation, and

Recoverable Tax.

Tax Code

Tax Code level and Line level calculation are the same except for how Payables groups and

rounds tax amounts. In some cases, the tax calculation results are the same. When the results

are different, the difference is usually a very small amount caused by rounding.

The results between Tax Code and Line level calculation will differ if at least the following

conditions are true:

• The Enable Recoverable Tax Financials option is enabled.

• The invoice has more than one Item distribution subject to tax.

• At least one of the Item distributions uses a tax code that is partially

recoverable.

See: Distribution Level (Line and Tax Code) Automatic Tax Calculation, and Recoverable

Tax.

None

If you choose None as the calculation level, Payables disables automatic tax calculation for

associated invoices. In the Suppliers window, the Supplier Sites window, and during invoice

entry, you can choose None as your Calculation Level if you have enabled the Allow

Calculation Level Override option at the previous level. When automatic tax calculation is

disabled, you can create tax distributions by matching to purchase orders, by allocating, by

using Distribution Sets, or by entering tax distributions manually. See: Entering Taxes When

You Do Not Use the Automatic Tax Calculation Feature.

If you enter a tax value and tax amount in the Invoices window and automatic tax calculation

is not enabled for an invoice, Payables will automatically create a tax distribution, but it will

not calculate the tax. It will not verify the tax amount until Invoice Validation. See: Tax

Amount Verification During Invoice Validation.

Overriding Tax Calculation Level

The automatic tax Calculation Level value defaults in the following order: Payables Options -

> Suppliers -> Supplier Site -> Invoices. You can adjust the default calculation level in the

Suppliers, Supplier Sites, and Invoices windows only if the Allow Calculation Level Override

option is currently enabled in the preceding window. You cannot enable the Allow

Calculation Level Override check box in the Suppliers or Supplier Sites window if the Allow

Calculation Level Override check box is not currently enabled in the previous window. If you

adjust an Allow Calculation Level Override check box, it immediately affects your ability to

change the Calculation Level and the Allow Calculation Level Override check box in the

succeeding window for existing and new records.

The value of the Allow Calculation Level Override check box does not default. The Allow

Calculation Level Override check box is always disabled for all new suppliers and supplier

sites.

Calculation of Tax Distributions For Line or Tax Code

Automatic Tax Calculation

If you use Line level or Tax Code level automatic tax calculation, Payables creates tax

distributions with calculated tax amounts, then groups them by unique combination of:

• Tax Code

• Tax Inclusive/Exclusive setting (setting of the Includes Tax check box)

If the Financials option Enable Recoverable Tax is enabled and there are recoverable tax

amounts, then Payables creates one recoverable tax distribution for each of these groups. For

recoverable distributions, Payables does the following:

• Assigns the GL account from the tax code

• Enables the Recoverable check box

Payables also calculates the nonrecoverable tax amounts per taxable distribution and groups

by a unique combination of the following:

• Tax Code

• Tax Inclusive/Exclusive setting (setting of the Includes Tax check box)

• GL account

• project information (if applicable)

• purchase order distribution (if applicable)

If there are nonrecoverable amounts, then one nonrecoverable tax distribution will be created

for each of these groups. The GL account assigned to these distributions will be from the

Item distribution(s) and these amounts become part of the acquisition cost of the item for

Oracle Projects and Oracle Assets.

During this calculation and grouping process, Payables rounds distribution amounts. When

the invoice is calculated at the Line level, the amounts per distribution are rounded to the tax

Precision or Minimum Accountable Unit defined at the supplier site level, and then grouped.

At the Tax Code level, the amounts are grouped first, and then rounded. If there is any

rounding difference between the sum of all the nonrecoverable distributions and the total

nonrecoverable tax amount, it is added to the largest of the nonrecoverable tax distributions.

In addition to instructing the system to favor either the Item distribution or the Tax

distribution during an exclusive tax calculation, the tax rounding rule at the supplier site level

instructs the system whether to favor the nonrecoverable or the recoverable distributions.

This may be mandated by law in some tax regimes. If the Rounding Rule is set to Up, any

partial units (beyond the precision) are included in the nonrecoverable distributions; if it is set

to Down, any partial units are included in to the recoverable distributions. If it is set to

Nearest, any partial amounts.5 or higher are included in the nonrecoverable distributions. For

example, a calculated tax amount of 15.28 is 30% recoverable, thus 70% nonrecoverable.

With a Rounding Rule of Up or Nearest, the nonrecoverable portion would be 15.28 * .7 =

10.696, which rounds to 10.70. The recoverable portion would therefore be 15.28 - 10.70 =

4.58. With a Rounding Rule of Down, however, the nonrecoverable portion of 10.696 would

be rounded to 10.69, and the recoverable portion would be 15.28 - 10.69 = 4.59.

If the Recovery Rate on the Item distribution line is blank, then the tax will be 0%

recoverable.

Setting Up Automatic Tax Calculation

You control invoice tax calculation in the Financials Options window, Payables Options

window, the Suppliers window, the Supplier Sites window, the Invoices window, and the

Distributions window. Tax calculation options default or cascade from either the Financials

Options or Payables Options window to suppliers, and then from suppliers to supplier sites,

and from supplier sites to invoices. You can control tax options and defaults at any level,

including invoice entry. This allows you to set up individual tax calculation methods for each

supplier site. If you allow override options, you can select individual tax calculation methods

for each invoice you enter.

Invoice tax options you select also determine the exact calculated tax amount. At the

Financials option level you select the level of precision in the tax amount or the smallest

monetary unit to which the tax is calculated. You also choose for each supplier site whether

Payables rounds up, down, or nearest. You can agree on these rules with each of your

suppliers so that your accounts will match each of your supplier's accounts.

Prerequisites

Discuss with your supplier what rounding rule you will both use to

calculate tax so that your accounts will match.

If you want to record recoverable and partially recoverable taxes, then

enable Recoverable Tax. See: Setting Up Payables for Recoverable Tax or for

Automatic Tax Calculation for Proration.

Define tax codes or tax groups. See: Tax Codes or Tax Groups.

To set up Automatic Tax Calculation:

1. Enable the Use Automatic Tax Calculation option in the Invoice Tax region of the

Payables Options window.

2. Select tax options in the Tax tabbed region of the Financials Options window. See:

Tax Region of the Financial Options window.

Select any remaining Automatic Tax Calculation options in the Invoice Tax region of

the Payables Options window. See: Invoice Tax Payables Options.

3. (Only if you do not use Multi-organization support) For each supplier, adjust tax

options in the Invoice Tax region of the Suppliers window. See: Invoice Tax region of

the Suppliers and Supplier Sites windows.

4. For each supplier site, adjust tax options in the Invoice Tax region of the Supplier

Sites window.

Disabling Automatic Tax Calculation
