Complete Income Tax 2024 guide: progressive rates, calculation table, deductions, dependents, and online calculator for Brazilian workers.
Income Tax 2024 follows new taxation rules that every Brazilian worker needs to know. The progressive table determines how much IR you’ll pay based on your monthly income.
Understanding the rates and tax brackets is essential to correctly calculate the deduction from your salary and plan your personal finances.
Income Tax 2024 Table
IR tax brackets
The 2024 IR table maintains five tax brackets, with updated values reflecting annual adjustments. Each bracket has a specific rate that applies to taxable income.
The brackets are progressive, meaning you pay different rates only on the amount exceeding each threshold.
Important: The exemption continues up to R$ 2,112.00 monthly, benefiting lower-income workers.
Rates by income bracket
| Monthly Income Bracket | Rate | Deduction Amount |
|---|---|---|
| Up to R$ 2,112.00 | Exempt | R$ 0.00 |
| R$ 2,112.01 to R$ 2,826.65 | 7.5% | R$ 158.40 |
| R$ 2,826.66 to R$ 3,751.05 | 15% | R$ 370.40 |
| R$ 3,751.06 to R$ 4,664.68 | 22.5% | R$ 651.73 |
| Above R$ 4,664.68 | 27.5% | R$ 884.96 |
IR deduction amount
The deduction amount simplifies tax calculation. Instead of calculating each bracket separately, you apply the maximum rate to the entire calculation base and subtract the corresponding amount.
This methodology makes calculations faster and more accurate, especially in automated payrolls.
Example: Income of R$ 4,000 → Rate 22.5% → (R$ 4,000 × 22.5%) - R$ 651.73 = R$ 248.27 IR
How to calculate IR on salary
IRPF (income tax) calculation base
The calculation base for IR is not the total gross salary. First, you must deduct some mandatory and optional contributions:
- INSS (social security) contribution (up to the ceiling of R$ 7,786.02)
- Private pension contribution (up to 12% of income)
- Alimony (full amount)
Only after these deductions do you apply the IR table to the taxable base.
Permitted deductions
The system allows several monthly deductions that reduce the tax payable:
- Dependents: R$ 189.59 per dependent
- Private pension: up to 12% of gross income
- Alimony: full amount paid
- Union contribution: amount paid in the month
IR dependents
Each legal dependent reduces R$ 189.59 from the monthly calculation base. Dependents include:
- Children up to 21 years old (or 24 if university students)
- Spouse with no income or low income
- Parents over 65 financially dependent
- People with disabilities under your care
Tip: Check if it’s advantageous to declare your spouse as a dependent by comparing with separate filing.
IR calculation examples
Different salaries
Salary R$ 3,000.00 (no dependents):
- INSS: R$ 3,000 × 9% = R$ 270.00
- IR Base: R$ 3,000 - R$ 270 = R$ 2,730.00
- IR: Exempt (below R$ 2,826.65)
Salary R$ 5,000.00 (no dependents):
- INSS: R$ 5,000 × 11% = R$ 550.00
- IR Base: R$ 5,000 - R$ 550 = R$ 4,450.00
- IR: (R$ 4,450 × 22.5%) - R$ 651.73 = R$ 349.52
With and without dependents
Salary R$ 4,500.00 with 2 dependents:
| Item | No Dependents | With 2 Dependents |
|---|---|---|
| Gross salary | R$ 4,500.00 | R$ 4,500.00 |

Refund and tax payable
When to receive refund
A refund happens when you paid more IR during the year than you actually owed. The most common situations include:
- Deductible medical expenses and education costs
- Social security contributions above monthly deduction
- Variable income with lower earning months
- Dependents added during the year
Filing planning
To maximize your refund or reduce tax payable:
- Organize receipts for deductible expenses monthly
- Contribute to private pension up to the 12% limit
- Evaluate investments taxed at source vs. capital gains
- Consider donations to funds controlled by municipal councils
Strategy: Medical expenses have no deduction limit, unlike education (which is limited).

Frequently Asked Questions
What is the IR exemption bracket value for 2024?
The exemption bracket remains at up to R$ 2,112.00 monthly. Income above this amount starts being taxed at the 7.5% rate, but with a R$ 158.40 deduction to ensure progressivity.
How to calculate IR with dependents?
For each legal dependent, deduct R$ 189.59 from the calculation base before applying the IR table. Two dependents reduce R$ 379.18 from the monthly taxable base.
What’s the difference between withholding tax and filing tax?
Withholding tax is deducted monthly from salary using estimates. In the annual filing, you calculate the exact amount due, considering all income and deductions. The difference generates a refund or additional tax.
How much IR does private pension reduce?
Contributions to PGBL private pension can be deducted up to 12% of annual gross income. A person with R$ 5,000 monthly income can deduct up to R$ 7,200 per year, saving about R$ 1,980 in IR.
Do medical expenses have a deduction limit?
There is no limit for deducting medical and dental expenses for yourself, dependents, or alimony recipients. Unlike education expenses, which have an annual limit of R$ 3,561.50 per person.
How does IR work for variable income?
Variable income like commissions and profit sharing can generate excessive IR withholding in specific months. In the annual filing, calculation is done on total annual income, frequently generating refunds.
Do self-employed pay IR like CLT workers?
Self-employed follow the same progressive table, but need to calculate and pay IR monthly via monthly payment booklet or through contracting companies. Tax planning is more complex and important.
