Introduction
Payroll in Belgium requires registration with the National Social Security Office (NSSO), filing a DIMONA (Immediate Declaration) before every employee's first working day, quarterly DmfA (Multifunctional Declaration) salary filings, and employer social security contributions of around 27 percent of gross salary.
The national minimum wage floor, the Guaranteed Average Minimum Monthly Income (GAMMI), is €2,154.11 per month from January 2026, but around 100 Joint Labour Committees (JLCs) set sector-specific minimums that average roughly 19 percent higher and take precedence.
In this guide, we cover NSSO registration, DIMONA and DmfA declaration obligations, income tax brackets, the 13.92 pay structure, double holiday pay, Joint Labour Committee rules, and how to run compliant payroll in Belgium without a local entity.
Payroll process in Belgium
Aside from minor differences, the Belgium payroll process is similar to how it works in most countries, which is separated into three distinct phases.
Pre-payroll phase
During the pre-payroll phase, your business focuses on being prepared. You’ll need to gather documentation, confirm HR policies, and generally ensure your business is ready to begin paying employees while staying compliant.
Setting up the organization
Set up clear policies for your company to include:
- Business profile: Your company should have a registered business number associated with your PAN and TAN, which will be needed to send out things like tax forms and payslips.
- Work location: Requirements can change across locations, even if they’re all within the same country. Document location-specific policies for each workplace.
- Attendance: For attendance, you'll need to document timesheets, doctor’s notices for sick leave, or supervisor permission for requested time off.
- Leave policy: Employees are legally entitled to some categories of leave in Belgium, including parental leave, sick leave, and paid holidays. Belgians who work five days a week and have worked for a company for at least one year are entitled to 20 days of paid annual leave in addition to 10 public holidays, which are paid days off.
Statutory components
Belgium’s labor laws have specific requirements not only around salary and leave, but also others. Be sure to factor in statutory components like bonuses, pension funds, and any other applicable benefits.
Salary components
When structuring compensation packages, make sure to be compliant with Belgian labor laws, such as the minimum wage. A payroll provider in Belgium, such as Skuad, supports local compliance.

Pay schedule
|
White-collar employees are paid monthly, typically at the end of the month. Payment must be by bank transfer; cash is not the norm.
|
|
The 13.92 structure
|
Belgian employees commonly receive more than 12 months of pay across the year: 12 monthly salaries, plus a 13th-month (end-of-year) bonus, plus double holiday pay worth 92% of a month's salary. Twelve plus one plus 0.92 is where the 13.92 figure comes from. The two extra payments land at different times, so this is not purely "year-end" income.
|
|
13th-month / end-of-year bonus
|
Not required by national law, but made compulsory in most sectors through the applicable Joint Labour Committee. Usually paid in December.
|
|
Single holiday pay
|
The continued payment of regular salary during legal vacation days ensures that the employee receives the same salary across all 12 months, despite taking leave. Paid by the employer for white-collar staff each month, leave is taken.
|
|
Double holiday pay
|
A supplementary "vacation bonus" equal to 92% of the gross monthly salary, calculated on fixed and qualifying variable salary elements. Paid once a year, in practice in May or June. Employees who did not work the full preceding year receive 1/12th per month worked.
|
|
Double holiday pay treatment
|
Split for contributions: 85% of gross monthly salary carries a special employee social security contribution of 13.07%; the remaining 7% (additional double holiday pay) is free of that contribution. Both portions are subject to withholding tax at exceptional rates.
|
|
Mandatory declarations (DIMONA)
|
An immediate declaration to the National Social Security Office (NSSO) for every hire and departure. A Dimona IN must be filed before the employee's first working day, for any type of contract.
|
|
Mandatory declarations (DmfA)
|
A quarterly multifunctional declaration of work performed and salaries paid. It determines the social security contributions owed and feeds salary and work data to the Belgian social security institutions.
|
|
Employee information required
|
To run payroll and file declarations, you need each employee's Social Security Identification Number (SSIN), not generic HR fields. A worker without an SSIN can be registered via BelgianIDpro. Also capture start date, job details, gross salary and benefits, and bank (IBAN) details for payment.
|
|
Declaration outsourcing
|
Employers may mandate an accredited social secretariat or a payroll services firm to file declarations. Only an accredited social secretariat can collect and remit social security contributions on the employer's behalf; a payroll services firm cannot.
|
Payroll calculation phase
The main component of the process is the Belgium payroll calculation phase. Partnering with a payroll provider in Belgium can make this process easier.
Post-payroll phase
Salary payments
Once the payroll calculation is complete, you can send your bank advice to your corporate bank for salary disbursements.
Payroll accounting
After payments have been sent out, make sure to balance the accounts.
Payroll reporting and compliance
Deductions such as employee and employer contributions to social security must be withdrawn and remitted to the respective government agency. Due dates may vary depending on the agency.

Minimum wage
|
Belgium has no statutory minimum wage set by law. The national floor is the Guaranteed Average Minimum Monthly Income (GAMMI/GMMI), set by collective agreement no. 43: €2,154.11/month from 1 January 2026, rising to €2,189.81/month from 1 April 2026, for all workers aged 18+. The age and seniority tiers were abolished (experience criteria in 2015, remaining seniority steps in April 2022), so adults now get 100%. Around 100 joint committees set sectoral minimums, which are on average ~19% higher and take priority. Reduced rates apply to workers under 18 and students under 21 under the collective agreement no. 50.
|
|
Working hours
|
Standard full-time week is 38 hours, with a Sunday rest day. If an employee works a Sunday, a compensatory day off must be granted within six days. A one-hour break is required for shifts of at least a certain length. Daily and weekly maximums apply, with collective agreements governing arrangements.
|
|
Overtime
|
Overtime premiums are 50% on weekdays and Saturdays, and 100% on Sundays and public holidays. Statutory overtime ceilings apply (broadly 78 hours per quarter).
|
|
Income tax
|
Progressive federal rates of 25%, 40%, 45%, and 50%. For income year 2025 (filed 2026):
- 25% up to €16,320
- 40% from €16,320 to €28,800
- 45% from €28,800 to €49,840
- 50% above €49,840.
A tax-free allowance (~€10,910) applies as a discount, and communal/municipal taxes of 0–9% (average ~7%) are added on top.
|
|
Social security tax
|
The employee's share is 13.07% of gross compensation, with no cap. The employer's share currently varies around 27%. A special social security contribution also applies, deducted monthly from net salary, ranging from €9.30 to €60.94 per month, capped at €731.28 per family per year and settled via the tax return. Foreign employees who remain covered by their home country's scheme (e.g. under the Belgium/US agreement) may be exempt.
|
|
Sick leave
|
The employee is entitled to statutory sick pay for the first 30 days of absence, paid by the employer, at a rate based on normal salary and depending on contract type (white or blue-collar) and length of service. After 30 days, the health insurance fund (mutuelle/ziekenfonds) pays sickness benefits. The employee must notify the employer immediately and provide a medical certificate on request.
|
|
Maternity leave
|
15 weeks of maternity leave (17 weeks for a multiple birth). It is partly employer-paid at the start and largely covered by social security thereafter. Separately, the other parent's birth/paternity leave is 20 days (for births from 2023).
|
|
Adoption leave
|
Adoption leave applies when a child joins the family, taken within a set window of the child's registration.

What are the termination laws in Belgium?
|
Factor
|
Details
|
|
Two ways to terminate
|
An employer ends an open-ended contract either by serving a notice period or by paying an indemnity in lieu of notice. A combination is possible: serve part of the notice, then pay the indemnity for the remainder. No prior authorisation is needed, except for protected employees (employee representatives, prevention advisor).
|
|
Notice measured in weeks
|
Statutory notice periods are fixed by law, expressed in weeks, and depend only on seniority (aligned for blue and white-collar contracts from 1 January 2014). Notice must be in writing, state the start date and length, be in the correct language, and be served by registered mail or bailiff. The period starts on the Monday after the week's notice is given.
|
|
Employer notice scale (post-2014 contracts)
|
1 week (0–3 months); rising through 6 weeks (6–9 months), 12 weeks (2 years), 18 weeks (5 years), 27 weeks (8 years), 33 weeks (10 years), 48 weeks (15 years), 62 weeks (20 years), then +1 week per additional year.
|
|
Employee notice (resignation)
|
Capped at 13 weeks regardless of seniority. Examples: 1 week (0–3 months), 3 weeks (6–9 months), 6 weeks (2 years), 9 weeks (5 years), reaching the 13-week maximum at 8 years and staying there.
|
|
Indemnity in lieu of notice
|
Equal to the salary the employee would have earned over the notice period, calculated on the annual salary at termination, including statutory and contractual fringe benefits (13th month, bonuses, meal vouchers, company car, group insurance). No formalities are required when terminating this way. This is what "severance" means in Belgium; there is no per-year-of-service severance formula.
|
|
Termination for serious cause
|
Either party can terminate immediately for serious cause (a fault making continued employment impossible, e.g., theft, violence), with no notice and no indemnity. Strict formalities: dismiss within 3 working days of becoming aware of the facts, and notify the grounds by registered mail within a further 3 working days. Miss the deadlines, and the dismissal is void, triggering an indemnity in lieu of notice.
|
|
Right to reason for dismissal
|
Employees with more than 6 months' seniority can request the reason for dismissal. If the employer fails to give a timely explanation, a lump-sum civil fine of 2 weeks' salary is owed.
|
|
Manifestly unreasonable dismissal
|
If an open-ended dismissal is "unjustified" (unrelated to conduct, capability, or business needs, and one no reasonable employer would have made), the labour court can award 3 to 17 weeks' salary in damages.
|
|
Protected employees
|
Pregnant employees, those on maternity leave, harassment complainants, whistleblowers, and others cannot be dismissed on a protected ground. Violation triggers a protection indemnity of 3 or 6 months' salary on top of notice/indemnity. Employee representatives and the prevention advisor have heavier protection, with compensation ranging from 2 up to 8 years' salary (and 1–3 years for trade union delegates/prevention advisors).
|
|
Collective dismissal
|
Triggered over a 60-day period at: 10 employees (firms of 20–99), 10% (firms of 100–299), or 30 (firms of 300+). Requires prior information and consultation and notice to the authorities, plus a special monthly compensation for 4 months for employees with notice entitlement under 7 months.
|
|
Discriminatory dismissal
|
Adds a supplementary indemnity of 6 months' salary.
|
|
Challenge window
|
Any claim must be brought before the labour court within 1 year of termination, or it is time-barred.

FAQs
How much does it cost to run payroll in Belgium?
On top of gross salary, employer social security contributions run around 27 percent. Adding the 13th-month bonus, double holiday pay worth 92 percent of a monthly salary, and the Guaranteed Average Minimum Monthly Income (GAMMI) floor of €2,154.11 per month from January 2026, total employment cost runs well above base
How to set up a payroll system in Belgium?
Setting up payroll in Belgium requires NSSO registration, a DIMONA (Immediate Declaration) filed before the first employee's first day, and identifying the applicable Joint Labour Committee for sector minimum wages. Employers then run a monthly payroll with income tax and employee social security contributions of 13.07 percent deducted at source
What are the payroll laws in Belgium?
Payroll is governed by the Labour Act, tax legislation, and collective agreements. Employers must pay at least the guaranteed minimum wage, deduct progressive income tax, comply with working hours and overtime rules, and provide mandatory paid leave.
Is an EOR or a payroll provider better for hiring in Belgium?
A payroll provider processes wages but requires a registered Belgian entity and the client to remain as legal employer. An EOR is itself the legal employer, already registered with the NSSO and applicable Joint Labour Committee, so foreign companies can hire and pay in Belgium without entity setup
How quickly can you start paying an employee in Belgium?
The timeline varies, but an EOR can typically onboard a Belgian hire within one to two weeks, since NSSO registration, DIMONA filing infrastructure, and applicable Joint Labour Committee identification are already in place. Setting up your own Belgian entity before running payroll typically takes several weeks to months.
What is payroll in Belgium?
Payroll in Belgium is the regulated process of paying employees under Belgian labor law, including filing a DIMONA (Immediate Declaration) with the National Social Security Office (NSSO) before each employee's first working day, submitting quarterly DmfA (Multifunctional Declaration) returns, and deducting income tax and social security contributions each month.
