Frequently asked questions - online non-resident tax return
I am entering a joint return. How can my partner sign the return?
If you enter your return via Myminfin: your partner will also have to get access to the return via MyMinfin in order to sign it.
If you enter your return without authentication: a single signature is sufficient. This means that you can enter your return with your or your partner's national number/bis number.
How do I get an estimate of the tax amount I owe?
Before sending your return, click on “Calculate your tax” in the menu at the top of the screen.
Warning, it only is an estimate. In some cases, the final calculation of your tax indicated in your tax assessment notice (calculation note) may be different.
You don’t see any display on your screen? Your browser is probably blocking pop-ups. Open the pop-up via the notification at the top or bottom of your screen or change your browser settings.

You access your return without authentication
For security reasons, you cannot enter your account number in the return without getting authentication first.
In both cases, you can add or modify your account number when you receive your tax assessment notice (the procedure will be mentioned on the document).
I am trying to get access to the return, but I get a message saying that I am not a non-resident. What can I do?
It may happen that you are not recognised - wrongly - as a non-resident. In this case, get in touch with your tax collector office.
Our employees will only help you in French, Dutch or German. For legal reasons, they cannot use English or any other language.
I am married or in a legal cohabitation but I cannot complete the codes for my partner. What can I do?
If you are married or in a legal cohabitation, you must introduce a joint tax return with your partner. For most of the codes, you will have to fill in two columns.
If you only see one column in the return, this means that we are not aware of your marriage or legal cohabitation. We therefore invite you to let us know and correct your situation.
My tax return mentions my partner, but we are divorced, or I am a widower/widow. What can I do?
If the death or the divorce took place in 2022 or before, you must now file a tax return as a single person.
If you see two columns in the tax return, this means that we do not know that you are divorced or that your partner is deceased. In this case, please let us know and correct your situation.
