Belgium Employment Law & Compliance Guide for Employers
Key employment laws in Belgium: what employers need to know
Employment in Belgium is governed mainly by the Employment Contracts Act of 3 July 1978, the Labour Act of 16 March 1971 and binding sector agreements negotiated in joint committees (paritair comité / commission paritaire [joint labour committee]). Foreign employers are most often surprised by automatic wage indexation, notice periods that grow with length of service under the 2013 Single Status Act, and language laws that decide the contract language. This page summarises the core employer rules as of October 2026, with official sources.
Belgium employment rules at a glance
| Topic | What the rule is | Official source |
|---|---|---|
| Minimum wage | National GMMI [guaranteed average minimum monthly income]: EUR 2,233.61 a month gross for full-time workers aged 18+ from 1 July 2026 (after the April 2026 social-agreement step to EUR 2,189.81 and indexation). Most joint committees set higher sector minimums. | National Labour Council (CNT/NAR) – CLA 43 amounts, update of 1 July 2026 |
| Standard working hours | Maximum 38 hours a week on average and 8 hours a day (Labour Act of 16 March 1971). Many sectors work 40 hours with compensatory rest days. Longer days (up to 11 hours, 50 hours a week) need a specific legal basis. | European Commission EURES – Living and working conditions: Belgium |
| Overtime pay | Overtime is paid at 150% of normal pay, or 200% on Sundays and public holidays. It is allowed only in listed cases or within a limited voluntary-overtime quota, and usually must be offset by compensatory rest. | European Commission EURES – Living and working conditions: Belgium |
| Paid annual leave | 20 working days (4 weeks, 5-day week) after a full year of work in the previous calendar year. White-collar staff also receive double holiday pay of about 92% of monthly salary; manual workers are paid through a holiday fund. | European Commission EURES – Living and working conditions: Belgium |
| Public holidays | 10 paid public holidays: 1 January, Easter Monday, 1 May, Ascension, Whit Monday, 21 July, 15 August, 1 November, 11 November and 25 December. A holiday on a Sunday or usual rest day must be replaced by another paid day off. | European Commission EURES – Living and working conditions: Belgium |
| Sick leave | Employer pays guaranteed salary for the first month: 100% for 30 days for white-collar staff; 100% for 7 days, then a reduced top-up to day 30 for manual workers. The health insurance fund then pays 60% of pay, capped at EUR 183.13 a day (2026). | European Commission – Your social security rights in Belgium (2026 edition) |
| Maternity and parental leave | Maternity leave: 15 weeks (9 weeks after birth compulsory), paid by the health insurance fund at 82%, then 75% (capped). Other parent: 20 working days of birth leave, first 3 paid by the employer. Parental leave: 4 months full-time per parent per child. | European Commission – Your social security rights in Belgium (2026 edition) |
| Probation period | No probation period since 1 January 2014 (except student, temporary and agency work). Instead, for contracts starting on or after 1 August 2026, notice is 1 week for either party during the first 6 months. | FPS Employment – notice periods for dismissal, contracts from 1 January 2014 |
| Notice period | Set by length of service under the Single Status Act, e.g. 18 weeks at 5 years and 33 weeks at 10 years. Capped at 52 weeks for contracts starting from 1 June 2026. Notice by the employee is shorter, at most 13 weeks. | FPS Employment – notice periods for dismissal, contracts from 1 January 2014 |
| Severance pay | No separate statutory severance. The employer lets the employee work the notice or pays an indemnity in lieu of notice equal to pay and benefits for that period. A manifestly unreasonable dismissal can cost 3–17 extra weeks' pay (CLA 109). | FPS Employment – notice periods for dismissal, contracts from 1 January 2014 |
| Employer social contributions | About 27% of gross pay: a 25% basic contribution plus roughly 2–3% special contributions; higher for manual workers (based on 108% of pay). Reductions apply to low wages. The basic contribution is not due on pay above EUR 88,434 a quarter (from July 2026). | ONSS/RSZ administrative instructions – exemption above the salary ceiling |
| Employee social contributions | 13.07% of gross pay, with no ceiling. The employer also withholds a special social security contribution of up to EUR 731.28 a year per household, depending on family income. | PwC Worldwide Tax Summaries – Belgium, other taxes (professional source) |
| Income tax on salaries | Employer withholds bedrijfsvoorheffing / précompte professionnel [payroll withholding tax] monthly. Federal rates are 25%, 40%, 45% and 50% (income-year 2025 bands: to EUR 16,320; 28,800; 49,840; above), plus a 0–9% municipal surcharge. Bands are indexed yearly. | PwC Worldwide Tax Summaries – Belgium, taxes on personal income (professional source) |
| Mandatory bonuses and 13th-month pay | No 13th month by statute, but many joint-committee agreements require an end-of-year bonus, often one month's pay. Double holiday pay (about 92% of monthly salary for white-collar staff) is statutory. Year-end bonuses count towards the minimum wage. | FPS Employment – Salary and the guaranteed minimum income (GMMI) |
| Work permits for foreign nationals | Non-EU nationals working over 90 days need a single permit (work and residence) or an EU Blue Card. An employer based in Belgium applies online; the region decides on work, the Immigration Office on residence. Decision due within 4 months of admissibility. | Immigration Office (DOFI) – Single permit |
| Employment contract requirements | Open-ended full-time contracts may be oral, but fixed-term, part-time, student and temporary contracts must be written. Regional language laws impose Dutch, French or German. Each hire must be declared to social security (Dimona) before work starts. | European Commission EURES – Living and working conditions: Belgium |

FAQs: hiring employees in Belgium
Can a foreign company hire employees in Belgium without a local entity?
Yes. A foreign company can register with the National Social Security Office (RSZ / ONSS) as an employer without a Belgian establishment and run payroll through a social secretariat. It must still apply the joint committee rules, language laws and Dimona declarations. An Employer of Record is another option, but Belgian rules restricting the hiring-out of workers (Act of 24 July 1987) mean the arrangement needs careful structuring. Sponsoring a single permit requires an employer based in Belgium.
How much does an employee cost in Belgium on top of gross salary?
Budget roughly 27% of gross pay for employer social security contributions for white-collar staff, and more for manual workers. Reductions apply to low wages, and the basic contribution is not due on pay above EUR 88,434 a quarter. On top come double holiday pay (about 92% of a monthly salary), any sector end-of-year bonus, mandatory workplace accident insurance and occupational health service fees. Employees pay 13.07% social security plus withholding tax.
What is the minimum wage in Belgium in 2026?
The national guaranteed average minimum monthly income (GMMI) is EUR 2,233.61 gross a month for full-time workers aged 18 and over, applicable since July 2026. It rose to EUR 2,189.81 on 1 April 2026 and was indexed to EUR 2,233.61 on 1 July 2026. Most joint committees set higher sector minimums by job class and seniority, so check the sector scale first.
How much notice and severance does an employer owe when dismissing an employee in Belgium?
Notice depends on length of service: one week during the first six months for contracts starting from 1 August 2026, rising to 18 weeks at five years and 33 weeks at ten years. For contracts starting from 1 June 2026, notice is capped at 52 weeks. The employer may pay an indemnity in lieu instead. There is no separate statutory severance, but 3 to 17 weeks’ pay can be due for a manifestly unreasonable dismissal.
Can a company hire a foreign national in Belgium, and what permit is needed?
Yes. EU, EEA and Swiss nationals need no permit. Other nationals working more than 90 days need a single permit, which combines work and residence, or an EU Blue Card for highly qualified roles. An employer based in Belgium applies online; the region decides on the work part and the Immigration Office on residence. A decision is due within four months once the file is admissible.
Is it risky to engage contractors instead of employees in Belgium?
Yes, if the person works under the company’s authority in practice. Belgian law looks at the parties’ intention, freedom to organise working time and work, and hierarchical control, with a presumption of employment in some sectors. Reclassification leads to back social security contributions with surcharges, tax corrections and employee rights such as notice and holiday pay. A ruling from the Administrative Commission for the Regulation of Employment Relationships can reduce uncertainty.
