Income Tax 2025: Calculator and Complete Guide

Income Tax 2025 represents one of the main tax obligations for Brazilians, and understanding how to calculate it correctly can make all the difference in your financial planning. The annual IRPF (income tax) declaration involves millions of taxpayers every year, and being prepared is essential.

With the new tables and rules for 2025, it’s crucial to know the tax brackets, allowed deductions, and strategies to optimize your taxes. Using an income tax calculator can significantly simplify this process.

What is Income Tax 2025

The Individual Income Tax (IRPF) 2025 is a federal tax levied on income obtained during the 2024 calendar year. The declaration must be submitted to the Federal Revenue Service between March and May 2025.

The IR applies to various types of income and follows the principle of progressivity - the higher the income, the higher the rate applied.

Who needs to file

The requirement to file the 2025 IR applies to taxpayers who fall into at least one of the following situations:

• Taxable income exceeding R$ 30,639.90 in 2024
• Tax-exempt income above R$ 200,000.00
• Rural activity with gross revenue exceeding R$ 153,199.50
• Assets and rights worth more than R$ 800,000.00
• Stock market operations of any amount
• Capital gains from asset sales

Filing deadline

The 2025 IR declaration submission period traditionally occurs between:

• Start date: March 15, 2025
• Final deadline: May 31, 2025
• Time: until 11:59 PM on the last day

Declarations submitted after the deadline incur a minimum fine of R$ 165.74 or 1% per month on the tax due.

IRPF 2025 Table

The 2025 IR progressive table maintains the structure of five tax brackets, with amounts adjusted for accumulated inflation.

Tax brackets

Updated rates

The 2025 IR rates range from 7.5% to 27.5%, applied progressively. This means you only pay the corresponding rate on the amount that exceeds each bracket.

The exemption bracket has been expanded, benefiting taxpayers with income up to R$ 2,259.20 monthly.

How to calculate IR due

Income tax calculation involves three main steps: identifying income, applying deductions, and calculating the amount due.

Taxable income

The main income subject to IR includes:

• Salaries and wages
• Pro-labore and partner compensation
• INSS (social security) retirement and pensions
• Financial investment returns
• Rental income received
• Income as an individual (freelancer)

Allowed deductions

The main 2025 IR deductions are:

• Dependents: R$ 2,275.08 per dependent
• Medical expenses: full amount with no limit
• Education: up to R$ 3,561.50 per person
• Private pension: up to 12% of annual income
• Alimony: full court-determined amount
• INSS contributions: full amount of contributions

Step-by-step calculation

To calculate your IR due, follow these steps:

1. Add all taxable income for the year
2. Subtract allowed deductions (standard R$ 17,614.50 or itemized)
3. Apply the progressive table to the calculation base
4. Subtract IR withheld at source during the year
5. The result indicates whether you owe tax or are entitled to a refund

Example: Annual income of R$ 60,000 - Deductions of R$ 8,000 = Base of R$ 52,000 → IR due of R$ 6,617.77

Practical calculation example

Let’s calculate the IR for a taxpayer with annual income of R$ 48,000 in 2024:

Taxpayer data:

• Annual salary: R$ 48,000
• 1 dependent (child)
• Medical expenses: R$ 2,000
• Education: R$ 1,500
• IR withheld at source: R$ 2,500

Deduction calculation:

• Dependent: R$ 2,275.08
• Medical expenses: R$ 2,000
• Education: R$ 1,500
• Total deductions: R$ 5,775.08

IR due calculation:

• Calculation base: R$ 48,000 - R$ 5,775.08 = R$ 42,224.92
• IR due per table: R$ 4,717.24
• IR withheld at source: R$ 2,500
• Tax payable: R$ 2,217.24
