A Belgian payslip reads from top to bottom. From the gross pay the personal NSSO of 13.07% comes off, reduced by the work bonus on lower wages. That leaves the taxable pay. Withholding tax and the special contribution come off that, which gives the net pay. At the bottom come net allowances and deductions, such as the meal voucher share.
This guide is for the employer who wants to understand the payslips of his staff, and for the worker who wants to know where his gross pay goes. You read which items the law requires, what each line means and what a full payslip of 3,000 euro gross looks like. What a worker costs you in total as an employer is in employer cost Belgium.
What a Belgian payslip must show
At every final payment of wages the employer must give a statement, on paper or electronically. That is article 15 of the wage protection act. The joint committee of the employer sets the required content. If the committee decided nothing, the royal decree of 27 September 1966 applies. It lists 15 items, in a fixed order, as far as they are not superfluous.
| No. | Item on the payslip | What you read |
|---|---|---|
| 1 to 4 | employer, worker, registration number, period | who, for whom and for which month |
| 5 and 6 | amount of work done and base pay | hours, days or pieces, and the hourly or monthly wage |
| 7 | sums in cash, benefits in kind, total gross pay | pay, overtime, public holidays, guaranteed pay, bonuses |
| 8 and 9 | social security deductions and exempt amounts | the personal NSSO, after the work bonus |
| 10 | taxable amount | gross pay minus NSSO |
| 11 | withholding tax | the advance on personal income tax |
| 12 and 13 | tax exempt amounts and net sum granted | net allowances and the net pay |
| 14 | amounts to deduct | advances, benefits in kind, wage garnishment |
| 15 | net amount to be paid in cash | what lands in the account |
Not giving a payslip, or a payslip without the required items, is a level 3 offence under the Social Criminal Code. The administrative fine lies between € 1,000 and € 10,000, multiplied by the number of workers concerned. The duty itself is explained in is a payslip required. The payslip is also something else than the individual account, the yearly overview the employer keeps per worker.
Reading a Belgian payslip from gross to net
Every payslip follows the same sum, even when the layout differs from one payroll package to the next.
- Gross pay. The pay for the month's work, plus overtime, public holidays, bonuses and benefits in kind.
- Personal NSSO. 13.07% of the gross pay. For a blue-collar worker the base is 108% of the gross pay.
- Work bonus. On lower wages, a reduction of that NSSO.
- Taxable pay. Gross pay minus NSSO after the work bonus.
- Withholding tax. The advance on income tax, reduced by the tax work bonus.
- Special social security contribution. A separate deduction, based on the quarterly pay and the household.
- Net pay. What is left.
- Net allowances and deductions. Expense allowances added, the own share in meal vouchers or a garnishment taken off.
Employer contributions are not on the list of the royal decree. Some payslips show them for information, but they never come off the worker's pay. What the employer pays is in NSSO employer contribution.
Example: reading a Belgian payslip of 3,000 euro gross
Worked example
White-collar worker, full time, single, with meal vouchers
A white-collar worker works full time for 3,000 euro gross a month. He is single, has no dependent children and no company car. He gets 20 meal vouchers of € 10 in the month. The amounts apply from September 2026.
| Line on the payslip | Amount |
|---|---|
| Gross pay | 3,000 euro |
| Personal NSSO, 13.07% | € 392.10 |
| Work bonus, part A | € 110.54 |
| NSSO after work bonus | € 281.56 |
| Taxable pay | € 2,718.44 |
| Withholding tax by the scale | € 474.50 |
| Tax work bonus | € 36.63 |
| Withholding tax deducted | € 438 |
| Special social security contribution | € 19.24 |
| Net pay | € 2,261.20 |
| Own share meal vouchers, 20 times € 1.09 | € 21.80 |
| Net amount to be paid | € 2,239.40 |
Of the 3,000 euro gross, € 2,239.40 lands in the account. The meal vouchers themselves are not part of the net amount: the employer share of € 178.20 goes onto the meal voucher card; a voucher is worth at most € 10, of which the employer pays at most € 8.91. The withholding tax is calculated with the key formula of the FPS Finance for 2026; in the month of holiday pay or the year end bonus another rate applies.
The same example without meal vouchers, with the employer cost added, is in employer cost Belgium. You work out your own pay with the gross to net calculator.
NSSO and the work bonus on a Belgian payslip
The personal NSSO is 13.07% of the gross pay. For a blue-collar worker the NSSO counts on 108% of the gross pay, to make up for the holiday pay that runs through the holiday fund. On a blue-collar payslip the NSSO base is therefore higher than the gross pay.
| Status, 3,000 euro gross | NSSO base | Personal NSSO before work bonus |
|---|---|---|
| White-collar | 3,000 euro | € 392.10 |
| Blue-collar | € 3,240 | € 423.47 |
The work bonus lowers that NSSO on lower wages. For a full-time white-collar worker part A is at most € 127.54 a month up to a reference monthly wage of € 2,937.93. Above that it falls, to zero from € 3,403.62. On very low wages part B comes on top. The work bonus shows on the payslip as a separate line with a minus sign, or already netted in the NSSO. All amounts and the phase-out are in work bonus 2026.
Withholding tax on a Belgian payslip
Withholding tax is an advance on personal income tax. The employer deducts it from the taxable pay and pays it to the FPS Finance. The amount follows a scale that takes into account flat-rate work expenses up to € 6,070 a year, the tax-free allowance and the family situation. Dependent children or a partner without income lower the withholding tax.
The payslip also shows the tax work bonus: 33.14% of the work bonus part A comes off the withholding tax once more. In the example that is € 36.63. How withholding tax works is in what is withholding tax; what changes in 2027 is in withholding tax 2027. Over the whole year the withholding tax goes onto the form 281.10, which the worker uses for his tax return.
The special contribution on a Belgian payslip
The special social security contribution is a separate deduction, next to the ordinary NSSO, that depends on the quarterly pay and the household. A single person with a quarterly pay below € 5,836.14 pays nothing. The contribution is capped at € 60.94 a month. In the example it is € 19.24.
The scale per family situation and the thresholds are in special social security contribution.
Belgian payslip: what comes after net pay
Below the net pay are the amounts that are not taxed or that come off the net. The royal decree calls them the tax exempt amounts and the amounts to deduct.
| Line below the net pay | Sign | More explanation |
|---|---|---|
| Flat-rate expense allowance | added | expense allowance 2026 |
| Commuting or bicycle allowance | added | commuting allowance, bicycle allowance |
| Home working allowance | added | home working allowance 2026 |
| Own share meal vouchers, at least € 1.09 a voucher | deducted | meal vouchers employer contribution |
| Benefit in kind, such as the company car | deducted, it was added to the gross earlier | benefit in kind company car |
| Wage garnishment or assignment | deducted | wage garnishment as employer |
| Advance on pay | deducted | deducting from pay |
An employer cannot deduct just anything from pay. The law lists the deductions allowed, and the deductions outside tax and social security together may not exceed 20% of the net pay in cash. A garnishment follows its own limits: see wage garnishment 2027.
Payslip codes: why every Belgian payslip looks different
Workers often look up the meaning of the codes on their payslip. Those codes are not legal codes. Each secretariat and each payroll package numbers the pay items its own way: one code for normal hours, one for overtime, one for the year end bonus. The meaning is always printed next to the code. What is fixed is the order of the sum and the items of the royal decree.
The codes on the payslip are also something else than the pay codes in the DmfA, the quarterly return to the NSSO. Those are official and decide how an amount counts for social security: see what is the DmfA. The joint committee can require extra items, such as sector bonuses or a shift bonus. Which committee applies, you find with look up your joint committee.
Belgian payslip at holiday pay, year end bonus and leaving
Some months the payslip looks different. The double holiday pay of a white-collar worker and the year end bonus get their own withholding tax rate, which can be higher than on ordinary pay. What is left net of a bonus is in year end bonus net. A blue-collar worker does not get his holiday pay through the employer's payslip, but from the holiday fund: see holiday pay 2026.
At the end of the employment contract comes a final settlement with the leaving holiday pay and any notice pay. The worker also gets a C4. When and how the pay itself must be paid is in paying wages.
Five mistakes when reading a Belgian payslip
- Mixing up gross and taxable. Taxable pay is gross pay minus NSSO, not the net pay.
- Seeing the work bonus as a bonus. The work bonus is not extra pay, but a lower NSSO. It does not rise with the gross pay, it falls.
- Taking the special contribution for a mistake. It is a separate deduction that is settled per quarter.
- Counting meal vouchers in the net. The employer share goes onto the card, not into the account. The payslip only shows the own share, as a deduction.
- Reading employer contributions as a deduction. The 13.07% is the worker's share. The employer pays his own contributions on top of the gross pay. All amounts for 2026 are also on our figures page.
