Incoming taxpayers and incoming researchers in Belgium

If you employ Belgian or foreign employees (nationality does not matter) in Belgium, they might be eligible for a beneficial special tax status. This status must be applied to each employee individually.

Benefits for incoming taxpayers/researchers and employer

When the incoming taxpayer/researcher has a tax residency certificate of another country during the employment in Belgium, the taxpayer/researcher is treated as a non resident of Belgium when it comes to taxation. When such a certificate is not available, the taxpayer/researcher is treated as a resident for Belgian tax purposes. A part of the income is considered an expense allowance. For both the employer and the incoming taxpayer/researcher this can imply substantial benefits.

Strict conditions

In order to take advantage of this special tax regime certain requirements must be met, both by the employee and by the employer. The employee is either hired directly from abroad by a Belgian company, a Belgian establishment of a foreign company or a non-profit organisation. Or the employee is assigned by a foreign company (belonging to a multinational group) to a Belgian company, a Belgian establishment of the multinational group or a non-profit organisation.

Incoming taxpayers as well as incoming researchers within a 60 month period prior to the start of the employment in Belgium:

  • May not have lived within a distance of less than 150 kilometers from the Belgian border
  • May not have been taxed as a resident of Belgium
  • May not have been subject to Belgian non-resident taxation with respect to professional income.

For incoming taxpayers a minimum annual salary (including benefits in kind) applies of at least 75.000 EUR.

Incoming researchers must meet a certain degree requirement (master or doctor in specific scientific fields) or have at least 10 years of relevant professional experience. At least 80% of their work must be spent on R&D. Only employees, not company directors, are eligible for the special tax regime for incoming taxpayers.

The special tax regime must be requested for each employee individually and comes with quite a few administrative challenges.

Work documents and permits

You are considering hiring foreign employees to work in your Belgian organization? Make sure you pay attention to the procedures regarding work documents and permits in case it concerns non-EU nationals.

Changed legislation

Since 2019 it is possible to arrange the work and residence permit of non-EU citizens with one application, called the single permit. This single permit simplifies administration which might make it more attractive for you to recruit foreign staff. Foreign employees must carry their work document and permit with them at all times in order to be allowed to work in Belgium. EU citizens are exempted from these regulations. They are free to work in any of the EU member states.

Single permit procedure

So how does the single permit work? The basic rules are the same for everyone but, depending in the Region in Belgium, more specific rules and deviations might apply.
The Flemish rules are as follows:

If your non-EU employee is staying for less than 90 days, the combined permit procedure does not apply. In that case you will have to rely on the paper version. The combined permit is only valid if you recruit a non-EU citizen for a period of more than 90 days. You can submit a single permit application to the regional migration service for your future employee. On the website of you can view per category which documents you need to submit with such a request.

You want to hire someone with a foreign nationality but you are not sure that everything is taken care of? Contact Acerta for advice.

Audit international employment

The Belgian payroll administration and legislation regarding employment is a complicated matter. Employing in Belgium as a foreign employer implies even more rules to comply with. To make sure that you have all administration legally in order, you can rely on Acerta’s audit on your cross-border employment.
