Personal income tax

The personal income tax is a tax that every taxpayer in Belgium has to pay on their taxable annual income. You file this tax return every year, for the previous financial year. This means that in 2024, you file a tax return on your income in 2023. 


Personal income tax works progressively. This means that the tax rate increases as your income rises. The rates fluctuate between 25% and 50%. You need to add up your income as an employee and as a self-employed person to calculate the correct personal income tax rate.


The tax rates for your income in year 2023 (assessment year 2024) are as follows:

Tax Bracket:Income Bracket:Tax Rate:
Tax bracket 1Up to €15.200,-25%
Tax bracket 2€15.200,- to €26.830,-40%
Tax bracket 3€26.830,- to €46.440,-45%
Tax bracket 4Over €46.440,- 50%


Note: In addition, you also need to pay municipal tax. In Antwerp, the municipal tax is 8%. Furthermore, every taxpayer is entitled to a tax-free sum: a basic amount (at least 10.160 for the assessment year 2024) on which you pay no taxes.


TIP: don't forget your professional expenses. The limit amount of €10,260 refers to your net taxable annual income. That means: your turnover – (minus) your professional expenses. 


Student self-employed

Everyone pays taxes on their professional income, including student self-employed workers. But those who earn little do not have to pay taxes. Do you earn €10.160 net or less? Then you pay no taxes (income year 2023-tax year 2024). If you go over that, the income bracket up to €10.160 still remains exempt, these taxes only apply to what you earn above that amount.


Do you earn less than €10.160 in a year? Then you pay no personal income tax!



Self-employed in a secondary occupation

A self-employed person in a secondary occupation must pay tax on the income received and be included in 'deel II (part II)' of their tax return. To calculate tax, you add your income as a self-employed person to the salary you receive as an employee. So the tax rate for your income as a self-employed person depends on the income you declare as an employee. On top of that, as a self-employed person, you also pay municipal tax on the total amount of your personal income tax. 


Self-employed people in a secondary occupation are also entitled to the tax-free allowance. Do you earn €10.160 net or less? Then you pay no taxes (income year 2023-income year 2024). If you go over that, the income bracket up to €10,160 still remains exempt.


Self-employed in main occupation

As a self-employed person in main occupation, you pay personal income tax on your net professional income or net income: that is your annual turnover (the sum of your income minus VAT) minus your professional expenses (the expenses you incur to run your business). Provincial taxes, VAPZ premiums and social security contributions are also part of these expenses. On top of that, as a self-employed person, you also pay municipal tax on the total amount of your personal income tax. 


Everyone who needs to pay personal income tax is entitled to a 'tax-free allowance'. This means that part of the taxable income is not taxed. The tax-free sum for a self-employed in main occupation is €10.160,-.
