How to Calculate Income Tax (IRRF) and INSS Contributions in Brazil
Understanding how to calculate income tax (IRRF) in Brazil involves familiarizing yourself with the INSS contribution rates and the progressive income tax rates. Below is a detailed guide to help you navigate this process.
INSS Contribution Rates
(as of 05/01/2023 - MP No. 1,172/23)
The INSS contribution rates are structured progressively based on salary ranges. Here’s a breakdown of the current rates:
- Up to R$ 1,320.00: 7.50%
- From R$ 1,320.01 to R$ 2,571.29: 9.00%

- From R$ 3,856.95 to R$ 7,507.49: 14.00%
For more information, visit the official INSS website.
Example Calculation for INSS Contribution
If you earn R$ 7,507.49 per month, your INSS contribution is calculated as follows:
1. First Range: R$ 1,320.00 x 7.5% = R$ 99.00
2. Second Range: (R$ 2,571.29 - R$ 1,320.00) x 9% = R$ 112.62
3. Third Range: (R$ 3,856.94 - R$ 2,571.29) x 12% = R$ 154.28
4. Fourth Range: (R$ 7,507.49 - R$ 3,856.94) x 14% = R$ 511.07
Total INSS Contribution: R$ 99.00 + R$ 112.62 + R$ 154.28 + R$ 511.07 = R$ 876.97
Income Tax (IRRF) Rates
(as of 05/2023 - MP-1171)
The IRRF is calculated based on a progressive rate system with the following brackets:
- Up to R$ 2,112.00: 0.0% (No deduction)
- From R$ 2,112.01 to R$ 2,826.65: 7.5% (Deduct R$ 158.40)
- From R$ 2,826.66 to R$ 3,751.05: 15.0% (Deduct R$ 370.40)
- From R$ 3,751.06 to R$ 4,664.68: 22.5% (Deduct R$ 651.73)
- Above R$ 4,664.68: 27.5% (Deduct R$ 884.96)
For detailed information, refer to the [IRS Brazil](https://www.gov.br/receitafederal).
Example Calculation for IRRF
For a monthly salary of R$ 6,000.00, assuming no dependents or additional deductions, follow these steps:
1. Calculate the IRRF Base: Gross Salary - INSS Discount - Simplified Discount
- INSS Discount: R$ 665.92
- Simplified Discount: R$ 528.00
- IRRF Base: R$ 6,000.00 - R$ 665.92 - R$ 528.00 = R$ 4,806.08
2. Apply the Tax Brackets:
- First Range: R$ 2,112.00 (Exempt) = R$ 0.00
- Second Range: R$ 714.64 x 7.5% = R$ 53.60
- Third Range: R$ 924.39 x 15% = R$ 138.66
- Fourth Range: R$ 913.62 x 22.5% = R$ 205.56
- Fifth Range: R$ 141.43 x 27.5% = R$ 38.89
Total IRRF: R$ 0.00 + R$ 53.60 + R$ 138.66 + R$ 205.56 + R$ 38.89 = R$ 436.71
Effective Tax Rate: 7.28%
