Simples Nacional Brazil 2026: Annexes, Rates & DAS

Brazilian taxation can seem overwhelming to foreign entrepreneurs, but the Simples Nacional regime was specifically designed to simplify things for small and medium businesses. Instead of calculating and paying six or more taxes separately, Simples Nacional bundles them into a single monthly payment called the DAS. This guide explains how it works, who qualifies, and how to calculate your obligations.

What Is Simples Nacional?

Simples Nacional is a unified tax regime created by Brazilian Complementary Law 123/2006. It consolidates up to eight federal, state, and municipal taxes into one monthly payment. The regime is available to companies classified as ME (Microempresa) or EPP (Empresa de Pequeno Porte) with annual revenue up to R$ 4.8 million.

Taxes Included in the DAS

The single DAS payment covers:

• IRPJ — Corporate Income Tax
• CSLL — Social Contribution on Net Profit
• PIS — Social Integration Program
• COFINS — Contribution for Social Security Financing
• IPI — Tax on Manufactured Products (when applicable)
• ICMS — State Sales Tax (for commerce)
• ISS — Municipal Service Tax (for services)
• CPP — Employer Social Security Contribution

Who Can Opt for Simples Nacional?

Eligibility Requirements

• Annual gross revenue must not exceed R$ 4.8 million
• The company must be an ME or EPP (LTDA, SLU, or EI)
• All partners’ combined participation in other companies cannot exceed the revenue limit
• The company must not have outstanding tax debts with federal, state, or municipal authorities
• Certain activities are excluded (financial institutions, factoring companies, etc.)

Can Foreign-Owned Companies Use Simples Nacional?

Yes, with an important caveat. Companies with foreign partners who reside abroad are generally excluded from Simples Nacional. However, if the foreign partner has a CPF and resides in Brazil, the company may qualify. This is a critical point to discuss with your accountant before choosing your tax regime.

Understanding the Annexes

Simples Nacional organizes businesses into five annexes based on their primary activity. Each annex has its own progressive tax table:

The Factor R Rule

Companies in Annex V can potentially be taxed under the lower Annex III rates if their payroll expenses (including pro-labore) represent at least 28% of their gross revenue in the previous 12 months. This is called the Factor R calculation and is one of the most important tax planning strategies in Simples Nacional.

Factor R = Payroll in last 12 months / Revenue in last 12 months

If Factor R is 28% or higher, the company moves from Annex V to Annex III, which can reduce the effective tax rate significantly.

How to Calculate Your DAS

The DAS is calculated using a formula that considers your gross revenue over the previous 12 months:

Effective Rate = [(Revenue in 12 months x Nominal Rate) - Deduction] / Revenue in 12 months

Practical Example

Consider a service company in Annex III with R$ 300,000 in accumulated revenue over the past 12 months:

1. The applicable bracket has a nominal rate of 11.2% and a deduction of R$ 9,360
2. Effective rate = [(300,000 x 11.2%) - 9,360] / 300,000
3. Effective rate = [33,600 - 9,360] / 300,000
4. Effective rate = 24,240 / 300,000 = 8.08%

If this month’s revenue is R$ 25,000, the DAS payment would be R$ 25,000 x 8.08% = R$ 2,020.

DAS Payment and Deadlines

• The DAS is generated through the PGDAS-D system on the Simples Nacional portal
• Payment is due by the 20th of each month (for the previous month’s revenue)
• Even months with zero revenue require a declaration (though no tax is owed)
• Late payments incur a 0.33% daily fine plus SELIC interest rate

Simples Nacional vs. Other Tax Regimes

Lucro Presumido (Presumed Profit)

In Lucro Presumido, taxes are calculated based on a presumed profit margin set by law (typically 8% for commerce and 32% for services). The total tax burden usually ranges from 13% to 17% of gross revenue.

Lucro Real (Actual Profit)

Lucro Real calculates taxes based on actual net profit. It is mandatory for companies with revenue above R$ 78 million per year and can be advantageous for businesses with thin margins or operating losses.

Quick Comparison

Common Mistakes to Avoid

• Not monitoring your revenue bracket: As revenue grows, your effective rate increases. Crossing the R$ 4.8 million threshold forces you out of Simples Nacional entirely
• Ignoring Factor R: IT companies and consultants often overpay by staying in Annex V when they could qualify for Annex III
• Missing DAS deadlines: Accumulated late payments can lead to exclusion from the regime
• Choosing wrong CNAE codes: Your primary CNAE determines which annex applies to your company

How SedeFiscal Fits In

Your company address plays a role in taxation because the ISS (Municipal Service Tax) rate varies by city. By establishing your company at a SedeFiscal address in Porto Alegre, you benefit from competitive ISS rates while maintaining a professional business presence. Combined with the Simples Nacional regime, this can help optimize your overall tax position.

Next Steps

Tax planning in Brazil is not a set-it-and-forget-it exercise. Work with a qualified accountant to review your regime annually, monitor your Factor R, and ensure you are taking advantage of every legal optimization available. The right tax structure can mean the difference between thriving and merely surviving in the Brazilian market.
