(BRA) About calculation of taxes [AX 2012]

Updated: February 7, 2013

Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2

Microsoft Dynamics AX calculates Brazilian taxes based on the tax type that you specify for the sales tax code. You can set up and calculate sales taxes on sales, purchases, transfers between fiscal establishments, delivery of items to a third party, or receipt of items from a third party.

You can set up taxation codes for Imposto sobre Circulação de Mercadorias e Serviços (ICMS), Imposto sobre Produtos Industrializados (IPI), Program de Integracao Social (PIS), and Contribuição para Financiamento da Seguridade Social (COFINS) taxes. The taxation codes are used for fiscal reporting and generating federal electronic fiscal documents (NF-e). You can also set up taxation codes for other tax types. When you set up a taxation code for a tax type, you assign a fiscal value to indicate the type of treatment that applies to taxes, such as taxable, not taxable or exempt, or taxable without credit. When a taxation code is not set up for a tax type, you can set up the fiscal value by selecting the Without tax credit and Exempt check boxes in the Sales tax groups and Item sales tax groups forms. Sales taxes are calculated and saved in the Posted sales tax form.

You can specify a default taxation code for the sales tax code in the Taxation code field on the Calculation FastTab in the Sales tax codes form. You can also specify the taxation code for a sales tax code:

  • When you attach the sales tax code to a sales tax group and the sales tax code is exempt.

  • When you attach the sales tax code to an item sales tax group.

When you create and post tax transactions from sales orders, purchase orders, free text invoices, or project invoice proposals, the taxes are calculated based on either the fiscal value of taxation codes that are selected in the Fiscal value field in the Taxation code form, or the fiscal value that is determined based on the Without tax credit and Exempt check boxes in the Sales tax groups and Item sales tax groups forms. The tax base and tax amount are displayed in the Posted sales tax and Temporary sales tax transactions forms, as follows:

  • For transactions with taxation codes that have a 1. with credit/debit fiscal value, or item sales tax groups for which the Without tax credit check box is not selected, the amount that the sales tax is calculated for is equal to the taxable base amount. Sales tax is calculated according to the tax rate and is updated in the Actual sales tax amount field.

  • For transactions with taxation codes that have a 2. without credit/debit (exempt or not taxable) fiscal value, or sales tax groups or item sales tax groups for which the Exempt check box is selected, the exempt base amount is equal to the transaction value, and no tax amount is calculated.

  • For transactions with taxation codes that have a 3. without credit/debit (other) fiscal value, or item sales tax groups for which the Without tax credit check box is selected, the other base amount is equal to the transaction value. The sales tax amount is calculated according to the tax rate and is updated in the Other tax amount field.

For a base transaction amount of BRL 1,000.00 and a tax rate of 18 percent, Microsoft Dynamics AX calculates the taxes as follows for the different fiscal values.
