Income Tax 2025 remains one of the main tax obligations for Brazilians. With changes in exemption brackets and rates, it’s essential to understand how to correctly calculate IR to avoid problems with Receita Federal (Brazilian IRS).
For those who earn above R$ 2,259.20 monthly, the discount already happens at the source. But when filing the annual return, many discover they must pay more or are entitled to a refund.
What is Income Tax
Personal Income Tax (IRPF - individual income tax) is a federal tax charged on taxpayers’ earnings. It applies to salaries, rent, financial investments, and other income sources.
The tax amount varies according to total annual income and legal deductions allowed by Receita Federal.

Updated rates
The 2025 IRPF rates haven’t changed from the previous year. The exemption bracket remains at R$ 2,259.20 monthly, equivalent to R$ 27,110.40 annually.
For higher income, the calculation follows the progressive table, where each bracket has its specific rate applied only to the excess amount.
How to calculate step by step
Income tax calculation follows a logical sequence that considers income, deductions, and progressive rate application.
Taxable income
The following are considered taxable income:
- Salaries and pro-labore
- 13th salary (without advance payment)
- Rent received
- Alimony received
- Financial investment returns
- Retirement and pensions (taxable portion)
Allowed deductions
The main legal deductions that reduce IR calculation base are:
- INSS (social security) contribution: full amount paid during the year
- Dependents: R$ 2,275.08 per dependent
- Medical expenses: full amount with no limit
- Education: up to R$ 3,561.50 per person (holder + dependents)
- Alimony: full amount paid by court decision
- Private pension contribution (PGBL): up to 12% of taxable income
Tax due calculation
The calculation follows this sequence:
- Sum of annual taxable income
- Subtract legal deductions = Calculation base
- Apply progressive table
- Subtract tax already withheld at source = Tax due or to be refunded
Example: Annual income of R$ 60,000 - Deductions of R$ 8,000 = Base of R$ 52,000 Tax by table: R$ 6,694.00 - IR withheld at source: R$ 7,200 = Refund of R$ 506.00
Practical calculation example
Let’s calculate Maria’s IR, who had the following income in 2024:
- Annual salary: R$ 48,000.00
- 13th salary: R$ 4,000.00
- Savings account returns: R$ 1,200.00
- Total taxable: R$ 53,200.00
Maria’s deductions:
- INSS paid: R$ 4,320.00
- Health insurance: R$ 2,400.00
- 1 dependent: R$ 2,275.08
- Total deductions: R$ 8,995.08
Calculation base: R$ 53,200.00 - R$ 8,995.08 = R$ 44,204.92
Tax due (by annual table):
- Up to R$ 27,110.40: exempt
- From R$ 27,110.41 to R$ 44,204.92: 15% = R$ 2,564.18
- Total tax: R$ 2,564.18
If Maria had R$ 3,200.00 withheld at source, she’ll be entitled to a refund of R$ 635.82.
