Can a Foreign Company Hire Someone in Belgium Without a Local Office?
Expanding into Belgium is a smart move for growing companies. The country sits at the heart of Europe, offers a multilingual talent pool, and provides access to EU institutions. But does your company really need to incorporate a Belgian entity before making that first hire? The short answer is no. Belgian law allows foreign employers to hire workers directly without opening a local subsidiary. However, this flexibility comes with specific registration obligations, social security duties, and immigration rules you cannot afford to ignore. This guide breaks down every pathway, obligation, and risk so you can hire compliantly from day one.
The Legal Basis: Foreign Employers Without Establishment
A foreign employer without establishment is a company incorporated outside Belgium that directly employs staff on Belgian territory without creating a local legal entity. Under Belgian social security law, this is entirely permitted. According to L&E Global's Belgian hiring guide, a foreign employer does not need to work through a local entity to hire employees in Belgium.
This means your company can sign an employment contract governed by Belgian labour law, register with the relevant authorities, and run payroll, all without incorporating a BV/SRL or opening a branch. Many foreign companies, particularly scale-ups testing the Belgian market, use this approach as a first step.
Mandatory Registration Steps
While you do not need a local office, you still have administrative duties identical to those of a Belgian employer. Skipping any of these can result in fines or criminal prosecution.
1. Register with the Crossroads Bank for Enterprises (KBO/BCE)
Every employer operating in Belgium must obtain an enterprise number through the Crossroads Bank for Enterprises. This number is your unique identifier for all interactions with Belgian authorities.
2. Register with the NSSO via WIDE
The National Social Security Office (NSSO) is the body responsible for collecting employer and employee social security contributions. Registration is done through the online service WIDE. You must also file quarterly DmfA declarations reporting employment details and contributions paid.
3. Appoint a Belgian Representative and Obtain Insurance
Foreign employers must appoint an authorised officer in Belgium to keep employment documents and receive official NSSO correspondence. You are also legally required to take out occupational accident insurance with an accredited Belgian insurer. Most foreign employers delegate these tasks to a Belgian payroll provider through the Mahis platform.
The Employer of Record (EOR) Alternative
An Employer of Record (EOR) is a third-party organisation that acts as the legal employer of your workers in a specific country. The EOR handles contracts, payroll, tax withholding, and statutory benefits on your behalf while you retain day-to-day management of the employee.
EOR services allow companies to begin hiring in Belgium within one to two weeks without any local registration on their own part. However, this convenience comes at a cost: EOR providers typically charge a fixed monthly fee or a percentage of total employment costs. There is also a legal nuance in Belgium, where some experts caution that the triangular EOR relationship could raise questions under Belgian labour law regarding prohibited employee lending.
Direct Hiring vs. EOR vs. Subsidiary: Side-by-Side
| Criterion | Employer Without Establishment | Employer of Record (EOR) | Belgian Subsidiary (BV/SRL) |
|---|---|---|---|
| Local entity required? | No | No (EOR's entity) | Yes |
| Setup timeline | 2-3 weeks | 1-2 weeks | 4-8 weeks |
| NSSO registration by you? | Yes | No (handled by EOR) | Yes |
| Control over employment contract | Full | Limited | Full |
| Ongoing cost | Payroll provider fees | EOR service fee | Corporate overhead |
| Permanent establishment risk | Low to moderate | Low | Managed locally |
| Best for | 1-10 hires, market testing | Speed, short-term projects | Long-term, 10+ employees |
Work Permits and the Single Permit Procedure
The single permit is a combined work and residence authorisation introduced in Belgium in 2019. It applies to non-EEA nationals who will work in Belgium for more than 90 days. The application must be submitted in Belgium by the employer or an authorised representative to the competent regional authority.
A single permit is particularly relevant for highly skilled workers and managerial employees, who must meet specific salary thresholds and qualification criteria. For EEA and Swiss nationals, no work permit is needed thanks to free movement rules. If your company plans to sponsor a non-EU worker's immigration, having an experienced employment lawyer manage the process significantly reduces processing delays, which can otherwise stretch to 4 months or longer.
Dimona and Limosa Declarations
The Dimona declaration is an electronic notification to the NSSO that must be filed every time you hire, modify, or terminate an employee subject to Belgian social security. A Limosa declaration is a separate pre-activity notification required for posted workers coming to Belgium temporarily. Both are mandatory and non-negotiable.
Permanent Establishment and Tax Risks
A permanent establishment (PE) is a fixed place of business through which a company conducts its activities in a foreign country. Under Belgium's double tax treaties, a PE can be triggered by having an office, branch, or even an employee who habitually concludes contracts on the company's behalf.
The good news: in most cases, a foreign employer without establishment in Belgium does not create a PE, provided activities remain preparatory or auxiliary. To stay safe, limit employee authority to sign contracts, document work locations carefully, and consult a Belgian employment and tax adviser before your first hire.
Key Takeaways
- Belgian law explicitly permits foreign companies to hire employees without a local entity or office.
- You must still register with the KBO/BCE, NSSO, and obtain occupational accident insurance.
- A Belgian payroll provider (social secretariat) can manage most administrative obligations on your behalf.
- EOR services offer speed but may carry legal risks under Belgian rules on employee lending.
- Non-EEA workers need a single permit; the employer must initiate the application.
- Permanent establishment risk is manageable with proper structuring and legal advice.
- For long-term expansion with more than 10 employees, incorporating a BV/SRL may become more cost-effective.
Frequently Asked Questions
Can a foreign company legally hire an employee in Belgium without any local presence?
Yes. Belgian law allows a foreign employer to hire staff without establishing a subsidiary or branch. However, the company must register with the NSSO, obtain an enterprise number, take out occupational accident insurance, and appoint a local representative.
What is an employer without establishment in Belgium?
An employer without establishment (also called a non-residential employer) is a foreign company that directly employs workers in Belgium without creating a local legal entity. It fulfils all employer obligations remotely, typically through a Belgian payroll provider.
How long does it take to set up as a foreign employer in Belgium?
With the right payroll partner, the process of registering as a foreign employer without establishment takes approximately two to three weeks. An EOR can be operational in as little as one to two weeks.
Do I need a work permit for my Belgian employee?
EEA and Swiss nationals can work freely in Belgium. Non-EEA nationals generally require a single permit, which combines work and residence authorisation into one procedure. The employer must apply on their behalf through the competent regional authority.
What are the main tax risks of hiring in Belgium without a local entity?
The primary risk is triggering a permanent establishment, which would subject your company to Belgian corporate tax. This can happen if your employee has authority to conclude contracts or if you maintain a fixed place of business. Proper structuring and legal guidance minimise this risk considerably.
What is the NSSO and why does it matter?
The NSSO (National Social Security Office, or ONSS in French) is the Belgian authority that collects employer and employee social security contributions. Every company employing staff under the Belgian social security scheme must register with the NSSO and file quarterly declarations.
Is using an EOR legal in Belgium?
EOR arrangements are widely used, but Belgium has strict rules on prohibited employee lending (mise à disposition). Some legal experts warn that certain EOR structures may not fully comply with Belgian labour law. It is advisable to seek specialised legal counsel on employment contract structures before choosing this route.
What ongoing obligations does a foreign employer have in Belgium?
You must file quarterly DmfA declarations to the NSSO, submit Dimona notifications for each hiring or termination, withhold and remit wage taxes, provide mandatory employee benefits, and maintain occupational accident insurance.
