You file an M-form if you have only lived in the Netherlands for part of the year, for example because you emigrated from the Netherlands or immigrated to the Netherlands in 2020.

If you lived outside the Netherlands for part of a declaration year due to emigration or immigration, you should file a declaration using the M form. You can complete an M form up to 5 years ago. After 2020, the M-form can be completed online, for that you have to fill it in on paper if you want to do this yourself.

In most cases, the tax authorities will send an M-form by post after departure, but not always! Make sure that you are always easily accessible, if necessary keep a postal address in the Netherlands. You can of course also activate the message inbox on to be kept informed.

Is an M-form mandatory?

In the Netherlands you are obliged to file a declaration for an M-form if: – You have received a declaration letter. – You have received an M-form. – You have not received a tax return letter or M-form, but you know that you have to pay more than €47,- euros.

So this really depends on the above. But besides whether it is mandatory, it is also important that you will probably receive a refund by filing an M form. Because you were not employed for a whole year, it may be the case that too much tax has been levied.

Advantages of filing an M-form Tax Return

  • There is a high probability that it will result in a refund.
  • You also close the book with the Dutch tax authorities and if there are any questions, the inspector will ask the tax advisor.
  • The declaration is often more complex and therefore more error-prone.

Normally, the M form must be received by the tax authorities before 1 July of the following year. Of course, One Day Finance can request an extension for this from the tax authorities. This gives you an extra year to file the M-form declaration.
