Simples Nacional — Brazilian Simplified Tax Regime

Overview

Simples Nacional is the Brazilian simplified tax regime for micro-enterprises (annual revenue up to BRL 360,000) and small businesses (annual revenue between BRL 360,000 and BRL 4.8 million). Created by Complementary Law 123/2006, it unifies 8 federal, state and municipal taxes (IRPJ, CSLL, PIS, COFINS, IPI, CPP, ICMS, ISS) into a single monthly payment (DAS).

The regime is unique in international tax systems — combining three levels of government taxation (federal, state, municipal) in a single simplified framework. For foreign founders and small business operators in Brazil, Simples Nacional is the default consideration for revenue-eligible operations.

Eligibility and limits

• Micro-enterprise (ME): annual gross revenue up to BRL 360,000;
• Small Business (EPP): annual gross revenue between BRL 360,000 and BRL 4.8 million;
• Individual Micro-Entrepreneur (MEI): annual gross revenue up to BRL 81,000 — most simplified sub-regime within Simples;
• State ICMS sub-limit: some states set lower sub-limit than BRL 4.8M for ICMS portion;
• Export sub-limit: additional BRL 4.8M annually for export portion (total BRL 9.6M for export-exclusive companies).

Enrollment requires permitted activity (LC 123/2006 lists exclusions), partners without participation in other companies beyond specific limits, tax regularity. Exclusion occurs when revenue exceeds ceiling or other disqualifying cause arises.

Rates by anexo (annex)

Rates vary by anexo (annex) according to economic activity:

• Anexo I — commerce: rates 4-19%;
• Anexo II — industry: rates 4.5-30%;
• Anexo III — services with reduced taxation: rates 6-33%;
• Anexo IV — services with intermediate taxation: rates 4.5-33%;
• Anexo V — services with full taxation: rates 15.5-30.5%.

Within each anexo, rates progress by revenue band (5 bands per anexo). Effective rate depends on revenue accumulated over last 12 months.

Fator R: companies in Anexos III and V (some services) can have reduced rate to Anexo III if payroll is equal to or exceeds 28% of revenue (Fator R ≥ 0.28). Incentive mechanism for formal employment.

Known limitations

• No input credit: Simples companies cannot credit PIS/COFINS, ICMS or IPI on purchases. Customers of Simples companies also cannot credit those purchases (relevant for B2B sales — may make Simples supplier less competitive);
• STF Theme 69 not applicable: ICMS exclusion from PIS/COFINS base does not benefit Simples (cumulative embedded);
• Broad input concept (Theme 779 STJ) not applicable;
• Activity limitations: not all economic activities can opt for Simples (some categories of services, financial activities, factoring are excluded);
• Maximum export limit: BRL 4.8 million additional per year (total BRL 9.6 million for export-exclusive company) — but only for exported portion.

Simples Decision 2027 (Tax Reform)

The Tax Reform maintains Simples Nacional but creates the option (from 2027) for the optant to remain in cumulative regime (no input credit) or migrate to full IBS/CBS regular regime (full non-cumulativity).

The choice is strategic: B2B companies in Simples from 2027 lose competitiveness (corporate customers cannot credit IBS/CBS on purchases), while B2C with high margin can benefit from staying (simplified cumulative regime).

Decision scenarios

1. B2C commerce with average margin (Anexo I): Simples tends to remain advantageous;
2. B2B industry with intensive production chain (Anexo II): Simples becomes disadvantageous post-2027;
3. B2C professional services (Anexo III, Fator R applied): Simples continues advantageous;
4. B2B services (consulting, law, marketing for PJ): Simples becomes ambiguous — requires quantitative analysis;
5. Company near BRL 4.8M ceiling: plan migration to Lucro Presumido in 2026-2027 alongside Tax Reform transition.
