Verified 01 January 2024 - Legal and Administrative Information Directorate (Prime Minister)

The scale is used for calculating your tax.

He is progressive. It includes multiple income brackets, which each correspond to a different tax rate, which varies from 0% to 45%.

Tax scale To apply the previous tax to your taxable income, you must take into account the family quotient, that is, your number of shares, which depends on your situation and the number of people in your tax household.

Please note

Tax scale The processor is fixed every year. For example, the 2024 scale (applicable to 2023 income) is set by the 2024 budget.

The marginal tax rate (TMI) is the tax rate that applies to the highest tranche of your income.

The average tax rate is the average rate at which your income is taxed. It tells you the how much your tax represents in your income.

Here are some examples of the calculations:

For a single man

One unmarried (household of a single share) whose net taxable income is €30,000, without any reduction or deduction.

His family quotient is €30,000.

For the calculation of his tax:

  • Up to €11,294 : 0%
  • From €11,295 to  €28,797 : (€28,797 - €11,294) × 11% = €17,503 × 11% = €1,925.33
  • From €28,798 to €30,000 : (€30,000 - €28,797) x 30% = €1,203 × 30% = €360.90

Its gross tax is: €0 + €1,925.33 + €360.90 = €2,286.23.

The marginal tax rate (BIT) of this taxpayer is 30%, because its family quotient puts it in that range. But not all his income is taxed to 30%.

For a married couple or a past couple without children

One married couple or former couple without children (household of 2 units) having received taxable net income of €60,000.

His family quotient is €60,000 : 2 = €30,000.

For the calculation of his tax:

  • Up to €11,294 : 0%
  • From €11,295 to   €28,797 : (€28,797 - €11,294) × 11% = €17,503 × 11% = €1,925.33
  • From €28,798 to €30,000 : (€30,000 - €28,797) x 30% = €1,203 × 30% = €360.90

The gross tax for each member of the couple is: €0 + €1,925.33 + €360.90 = €2,286.23.

This tax must be multiplied by the number of shares in the tax household. In this example, it will be multiplied by 2 since it is a married or a former couple.

The couple will therefore have to pay a tax of €2,286.23 × 2, or €4,572.46.

The marginal tax rate (IMR.) for this couple is 30%, because its family quotient puts it in that range. But not all his income is taxed to 30%.

For a married or spent couple with 2 children

One married or past couple with 2 children (household of 3 parts, 1 part for each parent and 1 half part for each child) having received a net taxable income of €60,000.

His family quotient is €60,000 : 3 = €20,000.

For the calculation of his tax:

  • Up to €11,294 : 0%
  • From €11,295 to €20,000 : (€20,000 - €11,294) x 11% = €8,706× 11% = €957.66

This tax must be multiplied by the number of shares in the tax household. In this example, it will be multiplied by 3 since it is a married or past couple with 2 children.

The gross tax of the family is: €957.66 x 3, or €2,872.98

The marginal tax rate (BIT) for this family is 11%, because its family quotient puts it in that range. But not all his income is taxed to 11%.

For a single parent with 2 children

One single parent with 2 children (household of 2.5 shares, 1 share for the parent, 1 half share for each child in principal residence and 1 additional half share as a lone parent) who received taxable net income of €30,000.

His family quotient is €30,000 : 2.5 = €12,000.

  • Up to €11,294 : 0%
  • From €11,295 to  €12,000 : (€12,000 - €11,294) x 11% = €706 x 11% = €77.66

This tax must be multiplied by the number of shares in the tax household. In this example, it will be multiplied by 2.5 since it is a lone parent with 2 children.

Please note : the tax benefit is divided by two in the case of alternate residence.

The gross tax of the family is: €77.66 x 2.5, or €194.15.

The marginal tax rate (BIT) for this family is 11%, because its family quotient puts it in that range. But not all his income is taxed to 11%.

Income tax

2024 tax brackets and rates

Your tax is calculated in installments, based on the amount of your income. Each bracket corresponds to a tax rate (from 0 to 45%). If your annual income exceeds that of bracket 1 (€10,777), it will be covered by several successive brackets, as explained in the example.

Slices for 1 share of family quotient:

- Up to €11,294 (bracket 1): 0% tax rate

- From €11,295 to €28,797 (bracket 2): tax rate of 11%

- From € 28 798 to € 82 341 (bracket 3): 30% tax rate

- From €82 342 to €177 106 (bracket 4): tax rate of 41%

- More than €177 106 (bracket 5): tax rate of 45%

Example of calculation for 1 share of family quotient:

A single person (1 share) whose annual net taxable income is €30,000, the calculation of his tax is as follows:

- Up to €11,294 (tranche 1): €0

- From €11 295 to €28 797 (tranche 2): €1 925.33

- From €28 798 to €30 000 (tranche 3): €360.90

Total tax: €2,286.23, or 7.62% of his net taxable income.

That is, if you have more than one person in your tax household, the tax calculation takes that into account when determining your number of shares. This is the family quotient. This mechanism has an impact on the amount of your tax. In particular, it reduces the tax burden for families with children.
