Yes, you can hire remote employees in Belgium. Belgian labour law applies from the first day of employment, regardless of where the employer is incorporated. Foreign companies that engage workers in Belgium must comply with local employment contracts, social security registration, payroll tax obligations and sector-specific collective agreements. This guide explains the legal framework for remote employees Belgium, the registration steps required, the costs involved, and the practical risks that foreign employers most commonly overlook.
Belgian employment law is primarily governed by the Law of 3 July 1978 on Employment Contracts, which sets out the rules for individual employment relationships. This law applies whenever an employee habitually performs work in Belgium, regardless of the employer';s country of incorporation or the governing law chosen in the contract.
The concept of "structural telework" - where an employee regularly works from home or another location outside the employer';s premises - is regulated by the Collective Labour Agreement No. 85, concluded within the National Labour Council. CLA No. 85 requires that structural telework arrangements be formalised in writing, either as a separate addendum to the employment contract or as a clause within it. The written agreement must specify the location of telework, the applicable working hours, the equipment provided by the employer and the conditions for returning to office work.
A non-obvious requirement is that the employer must also provide or reimburse the costs of equipment and connectivity used for telework. Belgian practice treats a monthly flat-rate reimbursement for home office expenses as a tax-free allowance up to a ceiling set by the tax administration. Exceeding that ceiling without proper justification creates a taxable benefit.
Belgian labour law also distinguishes between employees and independent contractors. Misclassification - engaging a worker as a self-employed contractor when the relationship has the characteristics of employment - is a serious risk. The Law of 27 December 2006 on Diverse Provisions introduced criteria to assess the true nature of a working relationship, including the degree of subordination, the integration into the company';s organisation and the economic dependence of the worker. Belgian social inspection authorities actively enforce these rules.
Hiring remote employees Belgium triggers an obligation to register with the National Social Security Office (ONSS/RSZ). Social security contributions in Belgium are among the highest in the European Union, split between the employer and the employee. The employer';s share is a significant percentage of gross salary, and the employee';s share is withheld at source.
A foreign employer without a legal entity in Belgium can register directly with the ONSS/RSZ as a foreign employer. This registration allows the company to fulfil its social security obligations without incorporating a Belgian subsidiary. However, the registration process requires submitting corporate documents, appointing a local representative in some cases, and setting up a payroll system that reports contributions on a quarterly basis through the Dimona and DmfA electronic declarations.
Dimona is the Belgian electronic notification system for the start and end of each employment relationship. Every employer must submit a Dimona declaration before the employee';s first working day. Failure to do so exposes the employer to administrative fines and can trigger a presumption of undeclared work under Belgian social inspection rules.
Payroll withholding tax (précompte professionnel/bedrijfsvoorheffing) must also be withheld and remitted to the Belgian tax authorities. The withholding rates depend on the employee';s gross salary, family situation and applicable deductions. A foreign employer that fails to register for withholding tax creates a personal tax liability for the employee and potential penalties for the employer.
In practice, founders should consider engaging a Belgian payroll provider or a professional employer organisation (PEO) to handle these obligations, particularly when hiring the first one or two employees before deciding whether to establish a local entity.
Foreign companies hiring remote employees Belgium have two main structural options: direct employment and the employer of record (EOR) model.
Under direct employment, the foreign company registers with Belgian authorities, runs its own payroll and enters into employment contracts governed by Belgian law. This approach gives the employer full control over the employment relationship but requires ongoing compliance with Belgian labour law, sector collective agreements and administrative filings.
Under the EOR model, a Belgian entity - the employer of record - formally employs the worker on behalf of the foreign company. The EOR handles all Belgian compliance, including social security, payroll tax, employment contracts and mandatory benefits. The foreign company directs the work and pays a service fee to the EOR. This model is faster to implement and reduces the administrative burden, but it introduces a contractual intermediary and typically costs more per employee than direct employment.
Consider two practical scenarios. A US-based technology company wants to hire a single software developer in Brussels to cover the European time zone. The company has no other presence in Belgium and does not plan to expand further. In this case, an EOR arrangement is likely the most cost-effective and compliant solution, avoiding the need to register a full Belgian entity and manage local payroll independently.
By contrast, a German company already operating in Belgium through a branch office wants to allow its existing employees to work from home on a structural basis. Here, the company should formalise the telework arrangements under CLA No. 85, update employment contracts with written addenda, and ensure that home office expense reimbursements are correctly structured to qualify for the tax-free allowance.
A common mistake is assuming that an EOR arrangement eliminates all Belgian law exposure for the foreign company. Belgian courts can still examine the substance of the working relationship and, in some circumstances, hold the directing company jointly liable for employment obligations.

Belgium has an extensive system of sector-level collective labour agreements (CLAs) negotiated within Joint Committees (Paritaire Comités/Paritaire Comités). Each sector has its own Joint Committee, identified by a number, and the CLAs concluded within that committee are binding on all employers and employees in the sector, regardless of whether the employer is a member of an employers'; federation.
The applicable Joint Committee is determined by the main activity of the employer, not the job function of the employee. A foreign technology company hiring a developer in Belgium will typically fall under Joint Committee 200 (the residual white-collar committee) or a more specific committee depending on its activities. The sector CLA sets minimum wages, additional leave entitlements, end-of-year bonuses, sector-specific benefits and, in some cases, additional telework rules.
Many underestimate the impact of sector CLAs on total employment cost. The 13th month bonus (an end-of-year payment equivalent to one month';s gross salary) is mandatory in most sectors. Sector-level minimum wages often exceed the national interprofessional minimum wage. Eco-vouchers, meal vouchers and hospitalisation insurance are standard benefits in many sectors and are expected by Belgian employees even when not strictly mandatory.
Belgian employees are also entitled to statutory annual leave calculated on the basis of the previous year';s work. White-collar employees accrue leave differently from blue-collar employees, and the rules on holiday pay are complex. A non-obvious requirement is that white-collar employees receive a holiday pay advance (pécule de vacances/vakantiegeld) calculated as a percentage of their annual gross salary, paid in addition to regular salary during the leave period.
Working time is regulated by the Law of 16 March 1971 on Labour, which sets maximum daily and weekly working hours. Overtime requires specific justification and triggers additional pay or compensatory rest. Remote work does not exempt the employer from tracking working time for employees who are not autonomous in organising their schedule.
Hiring remote employees Belgium raises two distinct tax questions: the employee';s personal income tax position and the employer';s potential corporate tax exposure through a permanent establishment (PE).
Belgian residents are taxed on their worldwide income. An employee who lives and works in Belgium is subject to Belgian personal income tax, regardless of where the employer is located. The employer must withhold Belgian payroll tax (précompte professionnel) and remit it to the Belgian tax authorities. Where Belgium has a double tax treaty with the employer';s country of residence, the treaty may affect the allocation of taxing rights, but the Belgian withholding obligation typically remains.
The permanent establishment risk is more significant for foreign employers. Under Belgian domestic law and the OECD Model Tax Convention, a company can create a taxable presence in Belgium if an employee habitually concludes contracts on behalf of the company or if the employee';s home office constitutes a fixed place of business through which the company';s business is carried on. Belgian tax authorities have become more attentive to PE risks arising from remote work arrangements.
In practice, the PE risk is lower when the employee performs support or back-office functions and does not have authority to bind the company contractually. It is higher when the employee manages client relationships, negotiates contracts or represents the company commercially in Belgium. Foreign employers should document the scope of the employee';s authority carefully and seek tax advice before the employment begins.
Social security coordination is governed by EU Regulation 883/2004 for employees within the European Economic Area. Under the regulation, an employee who works more than 25 percent of their working time in their country of residence is subject to the social security legislation of that country. A Belgian resident working remotely for a foreign EU employer will therefore be subject to Belgian social security, and the foreign employer must register with ONSS/RSZ accordingly.
The total cost of employing a remote worker in Belgium is substantially higher than the gross salary agreed with the employee. Employer social security contributions add a significant percentage on top of gross salary, making Belgium one of the more expensive jurisdictions in Europe for employment costs.
Beyond social security, employers should budget for:
Professional fees for setting up a compliant employment structure usually start from the low thousands of euros, depending on the complexity of the arrangement and the number of employees. Ongoing compliance costs - payroll administration, annual filings, HR support - add to the total.
A common mistake is budgeting only for gross salary and employer social security contributions, overlooking sector benefits, holiday pay advances and the administrative cost of Belgian compliance. Foreign employers who underestimate these costs often find that the total employment cost is significantly higher than projected.

Does a foreign company need a Belgian entity to hire remote employees in Belgium?
No, a Belgian entity is not strictly required. A foreign company can register directly with the National Social Security Office (ONSS/RSZ) as a foreign employer and fulfil its payroll and social security obligations without incorporating a subsidiary or branch. Alternatively, it can use an employer of record to employ the worker formally in Belgium. However, if the company';s activities in Belgium grow - for example, if employees conclude contracts or manage clients locally - a permanent establishment or a formal entity may become necessary for tax and legal reasons. The choice depends on the scale of operations and the nature of the work performed.
How long does it take to set up compliant employment for a remote worker in Belgium?
The timeline depends on the route chosen. Using an employer of record, the employment can typically be set up within one to three weeks, as the EOR already has the necessary registrations in place. Direct registration with ONSS/RSZ as a foreign employer takes longer - typically four to eight weeks - because it requires submitting corporate documents, obtaining a Belgian employer number and setting up payroll infrastructure. The Dimona declaration must be submitted before the employee';s first working day, so planning ahead is essential. Drafting a compliant employment contract and telework addendum under CLA No. 85 should be done in parallel with the registration process.
What are the main risks of getting Belgian remote employment wrong?
The most significant risks are misclassification of an employee as an independent contractor, failure to register with ONSS/RSZ and non-compliance with sector collective agreements. Misclassification can result in back-payment of social security contributions, fines and requalification of the contract by Belgian courts. Failure to submit Dimona declarations triggers administrative penalties and can create a presumption of undeclared work. Non-compliance with sector CLAs - for example, failing to pay the 13th month bonus or sector minimum wages - exposes the employer to claims from the employee and potential inspections. Belgian social inspection authorities have broad powers to investigate and sanction non-compliant employers.

Hiring remote employees Belgium is entirely possible for foreign companies, but it requires careful attention to Belgian labour law, social security registration, sector collective agreements and tax obligations. The legal framework is detailed and the cost of non-compliance is high. Choosing the right employment structure - direct registration or employer of record - depends on the company';s plans, the number of employees and the nature of the work.
