Self-Employed Tax in Brazil

Brazil offers three primary tax structures for independent workers, each with distinct obligations and ceilings. Choosing the right structure depends on annual revenue, the nature of the activity, and whether regulated professional rules bar MEI registration. Working with a qualified tax professional familiar with Brazilian federal and municipal rules is the most reliable way to navigate the decision.

What taxes does a MEI pay each month?

The Microempreendedor Individual (MEI) regime was created to formalise micro-entrepreneurs earning up to BRL 81,000 per calendar year (roughly BRL 6,750 per month). Registered MEIs pay a single monthly document called the DAS (Documento de Arrecadacao do Simples Nacional). As of January 2026 - following the increase of the minimum wage to BRL 1,621 (Decree 12.797/2025) - the DAS breaks down as follows: INSS at 5% of the minimum wage equals BRL 81.05; ISS (Imposto Sobre Servicos, municipal service tax) adds BRL 5.00 for service activities; and ICMS (state goods-and-circulation tax) adds BRL 1.00 for commercial or industrial activities. A MEI providing only services therefore pays BRL 86.05 per month total. One employee may be hired at no lower than the applicable minimum wage or category floor, but employing a second worker disqualifies the MEI registration. Regulated intellectual professions - lawyers, physicians, architects, accountants, and most council-registered activities - cannot use MEI; those workers must operate as autonomo or open a company.

How does the carnê-leao monthly advance work for autonomos?

An autonomo (independent worker) who does not incorporate remains a natural person (pessoa fisica) and pays income tax via the carnê-leao mechanism - a mandatory monthly self-assessed advance under IRPF (Imposto de Renda Pessoa Fisica). Law 15.270/2025, effective 1 January 2026, expanded the zero-rate bracket to monthly income up to BRL 5,000, meaning autonomos earning up to that threshold owe no carnê-leao in that month. Income between BRL 5,000.01 and BRL 7,350 per month benefits from a progressive discount formula (BRL 978.62 minus 0.133145 x monthly income) that gradually phases the credit to zero at BRL 7,350. For income above BRL 7,350 the standard progressive IRPF table applies: 7.5% on the first taxable band, 15% on the next, 22.5% on the following, and 27.5% on amounts exceeding BRL 4,664.68 in the base-of-calculation column (after deductions). The monthly DARF payment uses code 0190 and is due by the last working day of the month after the income is received. All monthly advances reconcile in the annual DIRPF return.

In parallel, autonomos owe INSS as a contribuinte individual. The standard rate is 20% applied to the monthly contribution-salary declared, subject to a floor of BRL 1,621 (the 2026 minimum wage) and a ceiling of BRL 8,475.55 - the teto confirmed by INSS for 2026 after a 3.9% adjustment. Maximum monthly INSS contribution at the full rate is therefore BRL 1,695.11. A reduced plano simplificado rate of 11% is available, applied only to the minimum wage (giving BRL 178.31 per month), but workers who use it cannot access retirement by contribution time - only retirement by age.

What is Simples Nacional and who uses it?

Simples Nacional is a consolidated tax regime for small companies (pessoa juridica) - not for autonomos operating as natural persons. A self-employed worker who surpasses MEI revenue limits or works in a profession excluded from MEI typically opens a Microempresa (ME, up to BRL 360,000 per year) or Empresa de Pequeno Porte (EPP, up to BRL 4.8 million). Both can elect Simples Nacional, which collapses IRPJ, CSLL, PIS, COFINS, IPI, ICMS, and ISS into a single monthly DAS. Rates scale by cumulative 12-month revenue and activity annex: Anexo I (commerce) starts at 4.0% and reaches 19.0% in the top bracket; Anexo III (most professional services) starts at 6.0% and reaches 33.0%; the first bracket for Anexo I and III applies to revenue up to BRL 180,000 per year. Opting for Simples Nacional typically reduces the effective tax burden compared with taxation as an autonomo once revenue comfortably exceeds MEI limits, but the benefit depends on the annex, the Fator R ratio (payroll-to-revenue), and deductible costs - analysis by a qualified accountant (contador) is essential before election.

What is ISS and who collects it?

ISS (Imposto Sobre Servicos) is a municipal tax on services. Each of Brazil's over 5,500 municipalities sets its own ISS rate within the federal floor of 2% and ceiling of 5% established by Complementary Law 116/2003. An autonomo providing services directly to clients as a natural person may owe ISS to the municipality where the service is rendered, depending on local rules - some municipalities apply ISS to registered individual service providers (profissional autonomo), not just companies. MEIs pay ISS as part of the fixed monthly DAS (BRL 5.00). Companies under Simples Nacional have ISS included in the consolidated DAS rate. The ongoing consumption-tax reform (Constitutional Amendment 132/2023 and Complementary Law 214/2025) will phase ISS out between 2029 and 2033, replacing it alongside ICMS with the new IBS (Imposto sobre Bens e Servicos), but existing ISS obligations remain fully in force through the transition.

What is the annual DIRPF return and who must file?

All self-employed workers - whether MEI, autonomo, or company owner receiving pro-labore - must assess whether they are obliged to file the annual Declaracao de Imposto de Renda da Pessoa Fisica (DIRPF). For the 2026 filing season (reporting 2025 income), the Receita Federal required filing from anyone who received taxable income above BRL 35,584 in the calendar year, or who held assets and rights exceeding BRL 800,000 on 31 December. The 2026 window ran from 23 March to 29 May 2026. Autonomos who collected carnê-leao throughout the year reconcile all advance payments in the DIRPF; any overpayment generates a refund (restituicao), and any shortfall triggers a final DARF. MEIs who also receive income as a natural person (for instance, salary from an employer alongside MEI activity) must consolidate all income sources in the DIRPF. The MEI-specific annual declaration - DASN-SIMEI, which reports only gross MEI revenue and has nothing to do with personal IRPF - had a 2026 deadline of 31 May and is separate from the personal return.

The chart above illustrates approximate monthly tax burden for a service provider earning BRL 6,750 per month (the MEI monthly equivalent of the BRL 81,000 annual ceiling). Autonomo burden at that income level combines INSS at 20% of BRL 6,750 (BRL 1,350) plus carnê-leao IRPF in the transitional discount zone - actual IRPF may be reduced to near zero by the Law 15.270/2025 progressive discount for income below BRL 7,350. Simples Nacional estimate assumes Anexo III at the first bracket rate of 6%. These are illustrative figures only; individual deductions, dependants, and activity-specific rules alter the outcome materially. A qualified tax professional should model the structures against actual revenue and expense patterns before any structural decision is made.

Consult a qualified tax professional registered with the CFC (Conselho Federal de Contabilidade) or an OAB-registered tax lawyer before making any structural choice.
