Belgium · 2026 (assessment year 2027)
Belgium Salary calculator
Work out what a Belgian salary leaves in your pocket for income year 2026. The calculator removes the 13.07% employee social security contribution, applies the automatic lump-sum deduction for professional expenses, runs the federal scale from 25% to 50% with the tax-free sum, then adds the surcharge your commune levies on the federal bill. Because every commune sets its own percentage, the model fixes it at 7%, roughly the national average. It describes a single white-collar employee in the private sector with no dependants.

How it works
- Social security comes off first: 13.07% of your gross salary, with no upper limit.
- The taxman then grants employees an automatic expense deduction of 30% of what remains, capped at 6,070 euros for 2026. You may claim higher actual costs instead.
- The federal scale applies to the rest: 25% up to 16,720 euros, 40% to 29,510 euros, 45% to 51,070 euros, and 50% beyond that.
- The tax-free sum of 11,180 euros occupies the bottom of the scale, which knocks 2,795 euros off the federal bill.
- Your commune adds its own percentage of that federal tax. Rates differ across Belgium, so this calculator uses 7%, close to the national average.
- Gross salary minus social security minus the combined tax gives your net pay.
Net = gross - social security (13.07%) - federal tax - communal surcharge
Social security is a flat 13.07% of gross pay. The taxable base is what remains after that contribution and after the lump-sum expense deduction. The federal scale taxes the base in slices of 25%, 40%, 45% and 50%, then the tax-free sum removes the tax on the first 11,180 euros. The commune charges its surcharge as a percentage of the federal result, 7% in this model.

Worked example
A 45,000 euro salary in income year 2026 pays 5,881.50 euros in social security and about 8,660 euros in tax (8,093 federal plus 567 communal at 7%), leaving roughly 30,459 euros a year, or 2,538 euros a month. Around 32% of the gross never reaches the account.
Key facts
- Employee social security is a flat 13.07% of gross pay with no ceiling, unlike the capped systems of many neighbours.
- The 50% federal rate starts at 51,070 euros of taxable income, reached at a little under 66,000 euros of gross salary.
- Income tax is assessed on pay after social security, so the brackets never see your full gross.
- All 581 communes levy their own surcharge on the federal tax, which is why two identical salaries can net differently across a municipal border.
Tips
- Add up your real professional costs once a year. If commuting, home-office and training expenses beat 6,070 euros, claiming actual costs lowers the bill.
- Look up your commune in the FPS Finance rate list. Moving across a border from an 8% commune to a 6% one trims the surcharge by a quarter.
- Pension saving and long-term saving schemes earn a federal tax reduction up to annual ceilings, one of the few levers an employee controls directly.
- Benefits such as meal vouchers and an eco budget carry lighter charges than the same value paid as salary, so weigh the whole package when comparing offers.

Frequently asked questions
Why is the communal surcharge set to 7%?+
Each of Belgium’s communes votes its own percentage on top of the federal income tax, mostly between 0% and 9%. FPS Finance publishes the full list every year. This calculator cannot know where you live, so it applies 7%, which sits near the national average. A resident of a 0% commune such as Knokke-Heist keeps more; an 8.5% commune costs a little extra.
What is the lump-sum expense deduction?+
Employees automatically deduct 30% of their income after social security, capped at 6,070 euros for income year 2026, to cover the cost of working. No receipts are needed. If your real costs (commuting, a home office, training) run higher, you can claim the actual amount in your return instead.
Does the calculator include the work bonus?+
No. Employees on low gross wages pay less than the full 13.07% thanks to the work bonus, a reduction that tapers away as pay rises. Someone near the minimum wage will therefore take home more than shown here.
Why does my payslip show a different tax amount?+
Employers withhold "bedrijfsvoorheffing" (precompte professionnel) each month using separate scales set by FPS Finance. That withholding is only an advance. Your final position is settled through the tax return for the assessment year, where the figures here apply. Holiday pay and a thirteenth month are also withheld at their own exceptional rates during the year.
Are blue-collar workers treated the same?+
Not quite. Blue-collar social security is calculated on 108% of gross pay to fund holiday entitlements, so the contribution is slightly higher than the white-collar figure used here. The tax stages that follow are identical.
What about the special social security contribution?+
A separate "bijzondere bijdrage" of up to a few hundred euros a year is withheld on top of the 13.07%, scaled to household income and family situation. It is excluded here because it depends on a partner’s earnings, which the calculator does not ask for.
Things to watch
- These figures are estimates for orientation, not financial or tax advice. Confirm your own position with FPS Finance or a tax adviser before acting on them.
- Monthly withholding follows its own scales, so payslips will not match one twelfth of the annual result; the difference settles through your tax return.
- The special social security contribution, up to a few hundred euros a year depending on household income, is not included.
- Low gross wages attract the work bonus, so actual net pay near the minimum wage is higher than shown.
