Brazil Monthly Salary Tax Calculator (INSS + IRRF)
Estimate your Brazilian payroll taxes from gross monthly salary. This tool calculates employee INSS and IRRF withholding using progressive rates and gives an estimated net salary.
Important: estimates are for educational use and may not reflect every payroll rule, benefit, union agreement, or legal update.
How this Brazil tax calculator works
This brazil tax calculator is designed for a practical question: “If my gross monthly salary is X, how much might I take home after INSS and IRRF?” It focuses on the two most common employee deductions in Brazilian payroll:
- INSS: social security contribution, calculated progressively by salary band and capped at a maximum contribution.
- IRRF: monthly income tax withholding, calculated on a taxable base after allowable deductions.
The result gives you an estimated monthly net salary, total monthly taxes, and effective tax rate. It also compares deduction methods so you can see whether legal deductions or the simplified monthly discount appears more favorable.
Brazil payroll taxes in plain language
1) INSS (employee social security)
INSS is charged progressively. That means each part of your salary is taxed at the rate for its bracket, rather than one flat rate on the full amount. If salary exceeds the highest contributory band, INSS is capped.
In this calculator, the monthly INSS bands are:
- Up to R$ 1.412,00: 7.5%
- R$ 1.412,01 to R$ 2.666,68: 9%
- R$ 2.666,69 to R$ 4.000,03: 12%
- R$ 4.000,04 to R$ 7.786,02: 14%
2) IRRF (withheld income tax)
IRRF starts with a taxable base. The calculator uses this formula:
Taxable base = Gross salary - INSS - deductible amount
The deductible amount can be either:
- Legal deductions: dependents (R$ 189,59 each) + other deductible amount, or
- Simplified monthly discount: fixed R$ 564,80.
Then IRRF is calculated by bracket (with deduction parcel):
- Up to R$ 2.112,00: exempt
- R$ 2.112,01 to R$ 2.826,65: 7.5% (deduct R$ 158,40)
- R$ 2.826,66 to R$ 3.751,05: 15% (deduct R$ 370,40)
- 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)
Example calculation
Imagine a gross salary of R$ 6.500,00 with zero dependents and no additional deductions:
- INSS is calculated progressively across all contributory bands.
- Taxable base for IRRF = Gross - INSS - deduction method.
- IRRF is then determined using the applicable bracket and deduction parcel.
- Net salary = Gross - INSS - IRRF.
Because this calculator instantly compares legal and simplified deduction methods, you can test scenarios and quickly understand which approach could reduce monthly withholding.
When to use this calculator
- Before accepting a job offer in Brazil.
- When planning your monthly budget and savings targets.
- When evaluating salary negotiations.
- When validating rough payroll estimates from spreadsheets.
Tips to get better estimates
Include realistic deductions
If you have deductible payroll items, include them in “Other Deductible Amount” so your IRRF base is closer to reality.
Test with and without simplified discount
The simplified discount can be favorable for some salaries, while legal deductions may be better for others (especially with dependents and other eligible deductions).
Remember this is monthly withholding
Annual declaration adjustments, bonuses, 13th salary, benefits, and local payroll specifics can change the final tax outcome over the year.

Does it include every payroll rule in Brazil?
No. It does not model every legal nuance, employment contract rule, union convention, benefit package, or exceptional case.
Can I use this for freelancers or companies?
This version is focused on employee salary withholding (INSS + IRRF). Self-employed taxation and company taxation require different models.
