Tax Calculation Logic Overview

The tax rate is calculated for IPI and ICMS VAT tax in the following sequences:

IPI
ICMS
1. Tax Functional Matrix
2. Fiscal classification code
3. Item
1. Supplier site
2. Fiscal classification code (superfluous)
3. Tax exception by items
4. Tax exception by fiscal classification code
5. Tax locations (state ship-from, state ship-to)
When the tax rate is found in a sequence, Purchasing calculates the tax amount with the tax rate. Purchasing also considers any tax exception, such as reduced base amount, compounded base amount, exemptions, and special tax rates.

Note: The Tax Functional Matrix determines if IPI tax is applied. The tax rate and tax exceptions are determined based on the tax setup for fiscal classifications and items. For more information about the Tax Functional Matrix, see Defining the Tax Functional Matrix .
