Hiring in Belgium: Complete Guide 2027
Everything you need to know about hiring and managing employees in Belgium
Overview
Belgium is the most expensive Benelux country to employ in and the most regulated. The employer pays 25% basic ONSS on white-collar gross, plus the sector contributions set by the joint committee (CP 200 for most office staff), double holiday pay of 92% of a month in May or June and, in most sectors, a 13th month. An EOR quote runs 27 to 32% on top of gross before the premiums. The structural question is legal: the loi du 24 juillet 1987 bans leasing staff to a third party without a regional temporary-work licence, so ask every EOR which model it runs in Belgium.

PAYROLL & SETUP
Setting Up Payroll in Belgium
Payroll is monthly and starts with two registrations: the BCE/KBO enterprise number and an ONSS employer number. Before the first hour of work the employer files a Dimona declaration; every quarter it files the DmfA with each salary and contribution. The basic employer ONSS rate for white-collar staff is 25% of gross in 2026, reduced by the réduction structurelle on lower wages, plus the sector lines of the joint committee; the employee pays 13.07%, which the bonus à l'emploi wipes out around EUR 2,300 gross. On top come double holiday pay (92% of a month's gross, paid in May or June) and the end-of-year premium most sector CCTs require. Income tax is withheld monthly as précompte professionnel. The RMMMG is EUR 2,189.81 gross a month from 1 April 2026, indexed again in July 2026; sector wages are indexed automatically under the CCT, and the EOR must apply it on time. Meal vouchers and group insurance are common sector extras.

COMPLIANCE
Staff Leasing Licence and Notice Rules in Belgium
The loi du 24 juillet 1987 bans the mise à disposition of workers to a third party unless the lender is a licensed temporary-work agency, and the licence is regional: an erkenning in Flanders, an agrément in Brussels and Wallonia. An EOR here either holds that licence or runs a payroll service in which the client keeps authority. Ask which, in writing, with the licence number. Dismissal needs no prior approval, but since the single status of 2014 there is no probation period and notice is counted in weeks by seniority: 2 weeks in the first quarter, rising with each year, capped at 52 weeks for contracts signed from 1 June 2026. The employee may ask for the reasons (CCT 109); an unreasonable dismissal costs 3 to 17 weeks of extra pay.
