Income tax on salary is automatically deducted from payroll following the 2025 progressive table. For CLT (Brazilian labor law) workers, the calculation considers gross salary minus INSS (social security) contributions, applying rates according to income brackets.

The main change in 2025 is the adjustment of the exemption threshold to R$2,824.00, benefiting millions of Brazilian workers.

Income Tax on Salary

Who Must Pay

IR deduction on payroll is mandatory for all CLT workers who earn above the exemption limit. The employer automatically makes the deduction and forwards it to the Federal Revenue Service.

Subject to deduction:

  • CLT workers with monthly gross salary above R$2,824.00
  • Federal, state, and municipal civil servants
  • INSS pensioners with benefits exceeding the limit
  • Retirees who receive above the exemption bracket

Exemption Threshold

The exemption threshold in 2025 is R$2,824.00 monthly. This means those earning up to this amount don’t pay withholding income tax.

Example: Salary of R$2,800.00 → exempt from IR. Salary of R$3,000.00 → pays IR only on the excess amount.

Important: The calculation considers the tax base (gross salary minus INSS), not the total gross salary.

Updated Rates

The 2025 progressive table maintains the same rates, with adjustments only to bracket amounts:

Tax Base (R$)RateDeduction Amount (R$)
Up to 2,824.00Exempt-
2,824.01 to 3,751.057.5%212.08
3,751.06 to 4,664.6815%493.58
4,664.69 to 5,817.4322.5%843.32
Above 5,817.4327.5%1,134.25

Deduction Amount

The deduction amount simplifies tax calculation, avoiding complex bracket-by-bracket calculations. Apply the rate to the entire tax base and subtract the corresponding amount.

Simplified formula: IR = (Tax Base × Rate) - Deduction Amount

How to Calculate IR

Calculation Method

The calculation follows three main steps:

  1. Calculate the base: Gross salary - INSS - Alimony - Dependents
  2. Identify the bracket: Locate the rate in the 2025 table
  3. Apply the formula: (Base × Rate) - Deduction amount

Detailed Example

Scenario: CLT worker, salary R$4,500.00, no dependents.

Step 1 - INSS (11%):

  • INSS: R$4,500.00 × 11% = R$495.00
  • IR base: R$4,500.00 - R$495.00 = R$4,005.00

Step 2 - Identify bracket:

  • Base R$4,005.00 → 15% bracket (R$3,751.06 to R$4,664.68)

Step 3 - Calculate IR:

  • IR = (R$4,005.00 × 15%) - R$493.58
  • IR = R$600.75 - R$493.58 = R$107.17

Result: Monthly deduction of R$107.17 from payroll.

Permitted Deductions

Dependents

Each dependent reduces the monthly tax base by R$189.59. The following are considered dependents:

  • Children up to 21 years or up to 24 if university students
  • Spouse or partner without own income
  • Parents, grandparents, or great-grandparents over 65
  • Children or stepchildren with disabilities (no age limit)

Financial impact: Each dependent saves between R$14.22 and R$52.14 monthly in IR, depending on the bracket.

Alimony

Alimony amounts determined by court order are 100% deductible from the tax base. The deduction is made before applying the table.

Required documentation:

  • Court decision or approved agreement
  • Monthly payment receipts
  • Beneficiary’s CPF
