Pick the rate and direction. The 20.5% standard internal rate is pre-filled and editable; choose “Add tax” or “Remove tax”.

Why getting the Bahia split right matters

Tax is the part of the price most people get wrong, because the headline rate is rarely the whole story: in Brazil the internal rate differs by state, interstate sales use different rates, and tax substitution (ICMS-ST) changes who pays on some goods. This calculator starts from the general internal rate — and if your item qualifies for a different treatment, type that rate in and it calculates it instead.
