How corporate tax works in Brazil
Brazilian companies can generally be taxed under lucro real, lucro presumido or lucro arbitrado. The choice changes the base, compliance and cash flow; it is not just a choice between headline rates.
IRPJ is 15% on taxable profit, with a 10% additional charge on the portion exceeding BRL 20,000 per month of the relevant assessment period. Most non-financial companies also pay 9% CSLL, producing a common nominal combination of 24% below the surcharge threshold and up to 34% once the surcharge applies.
Financial, insurance and other regulated sectors can have higher CSLL rates or special bases. Large multinational groups may also face Brazil's domestic minimum top-up tax under the Pillar Two rules, while 2026 legislation changed some financial and betting-sector contribution rules.
Eligible micro and small companies can use Simples Nacional, a unified regime that can combine IRPJ, CSLL, PIS/Pasep, Cofins, IPI, ICMS, ISS and the employer social-security contribution in one payment. Its rates depend on activity and accumulated revenue, so it is not a universal low-rate substitute for ordinary corporate tax.
Corporate tax sits beside PIS and Cofins, IPI, ICMS, ISS, IOF, import taxes, payroll contributions, municipal fees and transfer pricing or withholding rules. The consumption reform begins its test year in 2026 and is scheduled to replace parts of the current system progressively through 2033.

Watch out for
- The 34% figure is a common nominal combination for ordinary companies, not a complete effective tax rate. Indirect taxes, payroll contributions, sector rates, incentives and the chosen profit regime can move the result substantially.
- Simples Nacional unifies taxes but does not eliminate every obligation. State and municipal sublimites, payroll treatment, import taxes and withholding can still apply outside the single payment.
- The 2026 CBS and IBS figures are test-year rates. The final transition changes PIS, Cofins, IPI, ICMS and ISS at different dates, with full replacement scheduled for 2033.
- Cross-border groups should model transfer pricing, Brazilian withholding, foreign tax credits, treaty entitlement, beneficial ownership and the Pillar Two domestic top-up rules where relevant.
Frequently asked questions
What is the corporate tax rate in Brazil?
Most companies face 15% IRPJ plus a 10% additional charge on monthly taxable profit above BRL 20,000, together with 9% CSLL. That produces a common nominal burden of 24% to 34% before other taxes.
Is Brazil's corporate tax really 34%?
It can be the common nominal maximum for ordinary companies once the IRPJ surcharge applies, but the effective result depends on lucro real, presumed profit, Simples Nacional, sector-specific CSLL and the wider federal, state, municipal and payroll system.
Can a small Brazilian business use one tax payment?
Eligible micro and small businesses may opt for Simples Nacional, which combines several taxes in a unified payment. Eligibility, activity, revenue and state or municipal sublimites must be checked first.
