What is the Brazil Simples Nacional Tax Calculator?
Simples Nacional is Brazil's simplified tax regime for small businesses (ME and EPP) with annual revenue up to R$4.8M. It consolidates multiple federal, state, and municipal taxes into a single monthly DAS payment. The effective tax rate depends on the cumulative 12-month revenue (RBT12) and the applicable Anexo (business category). Simples Nacional covers IRPJ, CSLL, PIS/Pasep, Cofins, IPI, ICMS, ISS, and CPP (employer INSS).
