Brazil Reverse ICMS / ISS Calculator

Final price (verified)R$0.00
Explain calculation
We reverse the tax using the standard formula:
Convert the rate to a decimal (e.g. 8.25% → 0.0825).
Divide the final price by (1 + rate) to get the pre-tax amount.
Subtract pre-tax from final to get the tax portion.
Enter a total and tax rate to see your breakdown.

ICMS, ISS, and layered taxes
Consumer prices embed multiple levies. São Paulo retail might show ~17–18% ICMS on goods while services in the same city use municipal ISS percentages.
PIS/COFINS affect B2B pricing but consumer reverse math starts with the total tax rate shown on the document.
Rio de Janeiro and Belo Horizonte buyers must read NF-e tax detail—not a memorized national average—before reverse calculation on tax-inclusive BRL totals.
Ecommerce and marketplaces
Mercado Livre and national retailers issue NF-e with tax detail. Enter that effective rate in the calculator rather than a generic 17% guess.
São Paulo D2C brands reverse embedded tax on tax-inclusive shelf prices before unit economics on pretax COGS and selling price.
State ICMS variation and Simples Nacional
ICMS alíquotas vary by state and NCM product code. Simples Nacional MEI sellers may embed tax differently on NF-e—always use the effective percentage on your nota, not an online default.
Services taxed under ISS in one municipality differ from goods taxed under ICMS in another—reverse using the rate on each NF-e line before summing pretax components.
Reverse from NF-e rate
Pretax = total ÷ (1 + invoice rate/100). Rate comes from your nota, not this page default.
Cross-state ecommerce must issue NF-e with correct origin and destination ICMS—reverse at the rate on the document, not the buyer's home state guess.
Brazil has no single VAT—use NF-e effective rate.
ICMS varies by state; ISS applies to many services.
