35th anniversary of the Belgian expatriate “special tax regime”

By Melissa Claessens

Belgium has an attractive special tax regime for foreign executives and specialised employees temporarily employed in Belgium. 8 August was its 35th (!) anniversary. Since that day in 1983 the currently applicable regime has been set out in a Tax Letter. Although the tax regime is very attractive, it is not flawless and the reshaping of Belgian income taxes, over the past years, also had its impact. In the coming weeks, we will highlight and summarise the main characteristics, good and bad, of this notorious special tax regime in a series of newsflashes.

This week newsflash 2: Past and current tax reforms and their impact.

2014 tax reform

No longer non-residents with and without an abode in Belgium

In 2014 several tax reforms have been implemented. One of them involved abolishing the distinction between non-residents having an abode (in Belgium) and those who did not. Instead, a threshold based on the income was put in place. Non-residents either earn at least 75% of their (worldwide) income in Belgium or they do not. Based on this threshold, it can be determined whether non-residents are eligible to benefit from so-called “tax reductions”. For expatriates benefiting from the special tax regime, the 75% threshold is breached if they have a professional travel outside Belgium (“travel exclusion”) for more than 25%.

Regionalization of tax reductions

In addition to this change, a further regionalization was also implemented with regard to certain tax reductions. Depending on the situation of the non-resident, a following distinction must be made in order to be able to invoke federal and / or regional tax reductions:

  • For federal tax reductions (e.g. attribution to partner, children at charge, personal tax credit, etc.), non-residents either benefit:
    • in full (i.e. non-residents earning at least 75% of their income in Belgium); or
    • only partial (i.e. non-residents earning less than 75% of their income in Belgium but who reside in France, Luxembourg or The Netherlands); or
    • not at all (i.e. non-residents who do not earn at least 75% of their income in Belgium nor reside in one of the mentioned countries) 
  • For regional tax reductions, the same distinction is made. However, for non-residents earning at least 75% of their income in Belgium, a further distinction is made between non-residents who reside in another EU member State and those who do not.

What about the actual impact ?

Assume a non-resident benefitting from the special tax status residing in Belgium with three children at charge and whose partner is not working. His travel exclusion equals 30%:

Net estimated income per year 76.464,33 67.074,51 67.682,80
Difference in net   -9.389,82 -8.781,53

For non-residents benefitting from a net guaranteed income, the 2014 tax reform likely resulted in a company cost increase (for compensating the net loss). For other non-residents, the net income decreased. Although the 2014 tax reform also brought some changes in the applicable income tax brackets reducing one’s overall income tax burden. The net difference remains nonetheless quite important.

2017 Tax reform

By law of 25 December 2017 tax benefits (and reductions) also became limited pro rata the number of months for non-residents who become, or stopped being, taxable in Belgium in the course of a year (i.e. due to their arrival or departure from Belgium). The tax letter of 28 February 2018 summarises these tax benefits. To determine the number of months on the basis of which the non-resident can claim the tax benefits, the 16th of the month is decisive.

For example:

  • A non-resident having the free use of a company car would prior to this reform benefit from a tax exempted amount of 400 EUR whereas the 400 EUR is to be limited to 9/12th if the non-resident arrives in Belgium on 18 March 2018.  
  • A non-resident who arrives in Belgium on 18 March 2018 and who is compliant with the 75%-threshold would have benefited in full from his personal tax credit prior to this reform, whereas because of this reform, he now sees his personal tax credit limited to 9/12th.


It is clear that above tax reforms have had a massive impact on the expatriate’s tax situation, either directly at charge of the non-resident, or at charge of the company depending on the applicable expat policy.
