Understanding the Purchase Tax Interface

Use the Purchase Tax Interface program (P76TX002) to select the tax exemptions pertaining to CBS, IBS, and IS taxes, and calculate these tax amounts. This program also enables you to enter the charges pertaining to a purchase order, such as custom duty and freight, and stores them in the Tax Calculation Amounts table (F76TX002). The system includes these charges in the taxable base for the purpose of tax calculation.

When you use the P76TX002 program to specify the tax exemptions for CBS and IBS taxes, select the CBS and IBS Tax Rule option from the Row menu. Then, from the Search and Select form, search for the combination of the tributary class and CST code to determine the applicable exemption. This form enables you to search for the applicable tax exemption by searching for the CST code and tributary code combination record on the basis of CST code value, tributary code value, or any of the parameters from purpose, first party business, third party business, item type, and particpant profile. You can search for the applicable exemption by entering a value in one or more of these fields. This gives you the flexibility to search for the tax exemption on the basis of the data that you want to search on. For CBS and IBS taxes, if the tax type is F, R, or D, you must select the Returned Tax checkbox for the system to enable the fields for returned tax rate and amount. If you enter the rate of the returned tax, the system automatically calculates the tax amount and stores the rate and the amount in F76TX002 when you save the record. However, if you enter the returned tax amount, the system leaves the tax rate blank in the table, and stores only the returned tax amount.

Note: When you select the Calculate Taxes option from the Form menu, the system subtracts ICMS, PIS, and COFINS from the taxable base of CBS, IBS, and IS based on the value provided in the 'Subtract taxes from taxable base of VAT/PIS/COFINS' processing option of P4312BR for the year 2026.

To specify the tax exemptions for IS taxes, select the IS Tax Rule option from the Row menu, and search for the combination record for CST code and tributary class code. This Search and Select window also gives you the flexibility to search for the applicable tax exemption on the basis of any values that you enter from the CST code, tributary code, and the other parameters, which are purpose, first party business, third party business, item type, and participant profile.

In addition to this, use the Standard Tax Rule option on the Row menu to enter the original taxes applicable on an order for the purpose of auditing details to be submitted to the government.

On the basis of tax type applicable for the type of tax, you must enter the returned tax details for the CBS and IBS taxes. You cannot enter returned tax details when the tax type for the respective tax is Z, E, I, or S.

With this, you have all your taxes and charges accounted in before you close the nota fiscal.

This program is a part of the purchase order receipt process. However, you can access it from the Purchase Order Processing - Brazil (G76B4311) menu also. See Forms Used to Enter Receipts and Add Nota Fiscal Information for Brazil
