Letters from Belastingdienst

Urgent, immediate action required! 
2 week final deadline, penalties may apply


The document "Aanmaning aangifte 20.." is basically, the second and last reminder with respect to the fact that the Dutch tax authorities did not receive your income tax return (timely).

It can mean that you did not file yet, but can also mean that extension was not granted, extension expired and/or that something went wrong with the application for extension for filing. 

If you received this letter, you urgently need to take action. A deadline is mentioned in the letter. Once you received an aanmaning it is no longer possible to apply for extension so you need to prepare your tax return and file it before the deadline.  

If you fail to take action within the given deadline, the Dutch tax authorities will proceed by issuing a tax assessment on the basis of an 'estimation'. On top of a high estimated income, they will issue a penalty (starting at € 469).

We can assist you with the preparation of your return, but in case of receipt of an aanmaning, always contact us with respect to the urgency.

Note that an "Aanmaning" can also relate to failing to pay your tax assessment timely.
