Employer Registration in Belgium

Registering as an employer in Belgium involves multiple steps and coordination with several government bodies. We manage the entire process on your behalf, whether you are a Belgian company starting to hire staff or a foreign employer entering the Belgian market for the first time.

Our services include obtaining your employer identification number, ensuring proper affiliation with a Belgian social security fund, and setting up tax and payroll accounts. This comprehensive approach allows you to focus on your core activities while we ensure compliance from day one.

Employment Contract Review & Drafting

Belgian labor law is highly regulated and requires precise contract drafting to avoid disputes and ensure legal compliance. We draft, review, or adapt employment agreements to reflect your company’s needs, including:

Permanent and fixed-term contracts

Part-time or flexible work arrangements

Executive and management contracts

Freelance and consultancy agreements

All contracts are carefully aligned with Belgian law and collective labor agreements (CLAs), ensuring your organization is fully protected while offering clarity to employees.

Cross-Border Employment Support

With increasing workforce mobility, many companies face complex challenges when employing staff across borders. We provide in-depth guidance on cross-border employment, helping you determine tax residency, applicable social security schemes, and regulatory obligations.

We ensure that employees remain compliant while minimizing unnecessary administrative burdens and costs. This includes coordinating with foreign payroll providers, ensuring correct tax withholdings, and structuring compensation packages for internationally mobile staff.

A1 Social Security Certificates

For employees working abroad temporarily, obtaining the correct A1 certificate is essential to ensure they remain covered under their home country’s social security system. We prepare and submit A1 applications, advise on eligibility, and handle renewals, ensuring compliance with EU legislation. This proactive approach provides clarity for both employers and employees.

Limosa Declarations

Belgium requires Limosa declarations for foreign employees and self-employed individuals performing work in Belgium temporarily. We manage these declarations on your behalf, ensuring your company avoids penalties or legal issues during labor inspections. Our team also monitors changes in Limosa regulations and ensures ongoing compliance for recurring postings and assignments.

Payroll Administration & Compliance

Our payroll solutions cover everything from initial setup to full outsourced payroll management:

Monthly salary calculations, tax deductions, and social security contributions

Submission of Dimona declarations and other mandatory filings

Preparation of pay slips and year-end tax documents

Advice on tax-friendly benefits, bonuses, and employee reimbursements

Whether you maintain payroll in-house or outsource it entirely, we ensure accuracy, confidentiality, and compliance with Belgian regulations.

After looking into the matter of hiring Belgian employees as a Dutch company who would then work in Belgium, we came up against a wall of numerous agencies and regulations that were very complex for us.

During the start-up phase, Intergest guided us through this process quickly, thanks to short lines of communication with expert permanent contacts, and took care of everything for us.
Intergest now takes care of all our personnel administration to our complete satisfaction.
