Belgium is an attractive, centrally located EU labour market, and employers can hire across the EU freely while using the single permit system for non-EU staff. A key feature in 2026 is that labour migration is regionalised, so the competent authority depends on where the work takes place, in Flanders, Wallonia, or the Brussels-Capital Region.

This guide is written for employers. It explains who can hire foreign workers in Belgium, which work-authorisation routes apply, the step-by-step hiring process, the contract, pay, tax, and social-security obligations, and the compliance pitfalls to avoid. It is practical and honest about how the process really works.

Can You Hire Foreign Workers in Belgium in 2026?

Yes, with clear employer routes:

• EU, EEA, and Swiss nationals can be hired freely, with no work permit required.
• Non-EU nationals need a single permit (combined work and residence), applied for with the employer through the competent region.
• The competent region (Flanders, Wallonia, or Brussels) depends on the place of employment, and rules differ between them.

In every case, the employer is central to the process, and the right to work must be confirmed before employment begins.

Work-Authorisation Routes

The main route is the single permit, combining work and residence authorisation, applied for through the relevant regional authority, often with a labour-market assessment for general roles and eased criteria for shortage occupations and highly skilled or EU Blue Card profiles. Posting of workers requires a Limosa declaration. Confirm the competent region and current criteria before relying on them.

Step-by-Step: How to Hire a Foreign Worker in Belgium

1. Define the role, confirm the pay meets legal or collective minimums, and check whether a labour-market test applies.
2. Identify the correct work-authorisation route for the worker’s nationality and role.
3. Make a written job offer that sets out the role, pay, hours, and start date.
4. Apply for or sponsor the required permit or authorisation, providing the employer’s documentation.
5. Support the worker’s visa or residency step where needed.
6. Register the worker for tax and social security before the start date.
7. Issue a compliant written contract and keep right-to-work records.
8. Onboard the worker and meet ongoing reporting duties.

Recruitment: Where to Find Foreign Workers

• Recruit EU candidates freely and via EURES and the regional services (VDAB, Forem, Actiris).
• Use the single permit for non-EU hires via the correct region.
• Target shortage-occupation lists for eased criteria.

The Employment Contract, Wages, and Conditions

The contract must comply with Belgian labour law and the applicable sector joint committee rules, which set minimum pay above the guaranteed national minimum (GGMMI); confirm the current figures. Belgium is multilingual (Dutch, French, German), and contracts follow regional language rules. The currency is the euro. Keep the contract, permit, and pay records on file.

Tax and Social Security Obligations

Register the worker with the National Social Security Office and operate payroll, withholding tax, and contributions; Belgian employer social charges are relatively high. Register before the start date and confirm current rates and the Dimona declaration requirement.

Compliance, Records, and Penalties

Submit the Dimona declaration for each worker, keep the single permit and right-to-work records, and ensure posted workers have a valid Limosa declaration. Employing without the correct permit or missing declarations can lead to significant penalties, so verify status before the start date and track renewals.

Common Mistakes Employers Make

• Applying through the wrong region for the place of work.
• Letting a non-EU worker start before the single permit is granted.
• Missing the Dimona declaration or Limosa for posted workers.
• Paying below the sector joint-committee minimum.
