Belgian Pensioners in Hungary Receive a Surprise Tax Letter

Marleen, 65, and André, 64, were living in Hungary and receiving their pensions there without having taxes withheld at the source.
That changed when they received an unexpected letter from the Belgian tax authorities.
The couple was suddenly asked to provide proof of their connection to Hungary, including evidence that they were Hungarian residents.
“Ineens moesten we bewijzen dat we Hongaren zijn,” they said “Suddenly, we had to prove that we are Hungarian.”
The unusual situation raised questions about where Belgian pensioners living abroad should pay taxes on their pension income.
Why did the Belgian tax authorities contact them?
Marleen and André are Belgian and had moved to Hungary. Like many people who retire abroad, their tax situation depends not only on where they live, but also on the tax rules between Belgium and their country of residence.
Cross-border pension taxation can be complicated because Belgium and another country may both have rules concerning pension income.
In this case, the couple received a letter from the Belgian tax authorities asking them to provide evidence concerning their situation in Hungary.
What does nationality have to do with it?
According to tax specialist Joost Klaps, the issue is not simply whether someone is Belgian or Hungarian. For tax purposes, residence can be more important than nationality.
A Belgian citizen who permanently lives in Hungary does not automatically have the same tax situation as someone who continues to live in Belgium.
Likewise, living in Hungary does not automatically mean that all income is taxed there. The applicable tax treaty and the type of pension involved can determine which country has the right to tax the income.
Why proving residence can become important?
When someone moves abroad, tax authorities may need evidence showing where that person is actually resident.
This can include official documents and other evidence demonstrating that the person genuinely lives in the country they claim as their place of residence.
That is why the request received by Marleen and André caused confusion. The couple understood the request as being asked to prove that they were Hungarian, even though the real issue was their tax residence.
A problem many Belgian pensioners abroad can face
Their case highlights a broader issue for Belgian retirees who choose to live in another country.
Moving to another European country does not necessarily mean that Belgian tax obligations disappear.
The answer can depend on several factors, including the person’s residence, the source and type of pension, and the tax treaty between Belgium and the country where they live.
For retirees, a change of residence can therefore have significant tax consequences.
The case of Marleen and André shows why international pension taxation can become complicated even for people who believe they have already settled their affairs after moving abroad.
And in their case, a letter from the tax authorities was enough to turn a quiet retirement in Hungary into a complicated tax question.
