In Tax Rate Maintenance, you can use the Tax Reason field to link ICMS tax exemption codes and PIS and COFINS credit calculation base codes to tax rates used in Brazilian transactions. The Tax Reason field also enables you to enter the IPI framing code for each IPI tax.

The ICMS tax exemption code identifies why tax does not apply in certain situations. This information is sent in the electronic nota fiscal XML file in the motDesICMS field.

The credit calculation base code identifies the credit calculation base earned in the PIS and COFINS tax period for transactions that generate credits for Sistema Público de Escrituração Digital (SPED) purposes.

The IPI framing code enables the validation of the nota fiscal XML file you send. The value in this field is used by default in Fiscal Receiving (5.20.1) and in shipper maintenance programs. This field can have numerous values, based on the fiscal class code.
