Income Tax 2024: Rates & Calculator for Brazil
Complete 2024 Income Tax table with rates, exemptions & practical examples. Free calculator to check your payroll deductions accurately.
The Individual Income Tax (IRPF - Individual Income Tax) for 2024 maintains the same brackets and rates from 2023, but it’s essential to know the updated values to correctly calculate deductions from your salary. The progressive table determines how much you pay according to your monthly income.
The IR calculation follows specific rules established by the Federal Revenue Service, considering mandatory deductions like INSS (social security) and dependents. Understanding these rules helps you better plan your financial life and avoid surprises in your annual tax return.
2024 Income Tax Table
Updated tax brackets
The 2024 IR table maintains five tax brackets with unchanged values since 2015. The government did not apply inflation correction, keeping the same income levels for each rate.
| Bracket | Monthly Calculation Base | Rate | Amount to Deduct |
|---|---|---|---|
| 1st | Up to R$ 2,112.00 | Exempt | - |
| 2nd | From R$ 2,112.01 to R$ 2,826.65 | 7.5% | R$ 158.40 |
| 3rd | From R$ 2,826.66 to R$ 3,751.05 | 15% | R$ 370.40 |
| 4th | From R$ 3,751.06 to R$ 4,664.68 | 22.5% | R$ 651.73 |
| 5th | Above R$ 4,664.68 | 27.5% | R$ 884.96 |
Rates and deductions by bracket
Each bracket has an amount to deduct that simplifies the calculation. This amount already considers the tax progressivity, avoiding the need to calculate bracket by bracket.
To use the table, you multiply your calculation base by the corresponding rate and subtract the deductible amount from your bracket.
Example: Calculation base of R$ 4,000 → 22.5% × R$ 4,000 - R$ 651.73 = R$ 248.27 in IR
How to calculate IR on salary
IRPF calculation base
The calculation base is not the gross salary. First you deduct the mandatory INSS (social security), then apply other legally permitted deductions.
The calculation follows this order:
- Gross salary
- Minus: INSS (social security) (up to R$ 908.85 in 2024)
- Minus: Court-ordered alimony
- Minus: Dependents (R$ 189.59 per dependent)
- Result: Base for IR calculation
Permitted deductions
The main monthly deductions include:
- Dependents: R$ 189.59 per child under 21 or university student up to 24
- Alimony: Full amount determined by court
- INSS: Mandatory social security contribution
- Private pension: Up to 12% of annual gross income
Our IR calculator automatically considers all these deductions to show the actual discount on your salary.
Income Tax Exemption
Who is entitled to exemption
Workers with income up to R$ 2,112.00 per month are exempt from Income Tax. This amount considers the final calculation base, after INSS (social security) discounts and deductions.
In practice, a higher gross salary may result in exemption after legal deductions, especially for those with dependents or paying alimony.
2024 exemption limit
The limit of R$ 2,112.00 was not adjusted in 2024. For comparison:
- 2015: R$ 1,903.98 (beginning of current bracket)
- 2024: R$ 2,112.00 (same value since 2015)
- Accumulated inflation: More than 60% in the period
Practical example: Salary of R$ 2,500 - INSS of R$ 225 - 1 dependent (R$ 189.59) = Base of R$ 2,085.41 → Exempt from IR
Practical calculation with examples
Different salary brackets
Let’s calculate IR for different income levels, considering a single worker without dependents:
Salary of R$ 3,000:
- INSS: R$ 270.00
- IR Base: R$ 2,730.00
- IR: 7.5% × R$ 2,730 - R$ 158.40 = R$ 46.35
Salary of R$ 5,000:
- INSS: R$ 550.00
- IR Base: R$ 4,450.00
- IR: 22.5% × R$ 4,450 - R$ 651.73 = R$ 349.52
Salary of R$ 8,000:
- INSS: R$ 908.85 (ceiling)
- IR Base: R$ 7,091.15
- IR: 27.5% × R$ 7,091.15 - R$ 884.96 = R$ 1,065.10
Comparison with previous years
The rates remain the same since 2015, but the purchasing power of exemption limits has decreased significantly. What was exempt a few years ago may now be subject to taxation due to inflation.
This lag mainly affects the middle class, who see their tax burden increase without real income growth.

Frequently Asked Questions
When is Income Tax deducted from salary?
The deduction is made monthly at source (company) for those with taxable income above R$ 2,112.00. The amount is calculated on the base after INSS (social security) and dependent deductions.
Can I deduct health insurance from monthly IR?
No. Health insurance can only be deducted in the annual IR return. In the monthly salary deduction, only INSS (social security), dependents and alimony are considered.
Do people with two jobs pay more IR?
Yes, usually. Each company calculates IR separately, without considering income from the other job. This may result in higher taxation, which will be adjusted in the annual return.
Does the 13th salary have different IR deduction?
The 13th salary follows the normal IR table, but is calculated separately from the monthly salary. If you receive it in two installments, each one is taxed individually.
Can a 25-year-old university student dependent be deducted?
No. The dependent deduction only applies until age 24 for university students, or 21 for non-university students. After this age, the person can no longer be declared as a dependent.
How do I know if I’m paying IR correctly?
Use our calculator to check if the deduction is correct. Compare the result with your pay stub and, if there’s a discrepancy, contact your company’s HR department.
Is it worth having dependents to reduce IR?
The deduction of R$ 189.59 per dependent reduces the calculation base, but it’s not a “direct discount.” The actual benefit depends on your tax bracket and can vary between R$ 14.22 (7.5%) up to R$ 52.13 (27.5%) per month per dependent.
