Income tax returns in the Netherlands

After you have submitted your Dutch tax return, you will receive a preliminary assessment from the tax authorities. In case you were invited by the tax authorities to submit your return before May 1, and you have filed your return before April 1, you will receive notice from the tax authorities before July 1. For returns filed after April 1, you will receive a notice after 10 to 12 weeks. If your tax return was submitted with either a C or an M form, it may even take up to 24 weeks or more.

Initially you will receive a preliminary assessment from the tax authorities, which is based on the tax return, but without being checked by the tax authorities. Once they have checked the return, a final assessment will follow.

If you cannot meet the deadline for filing the Dutch tax return, you can request for an extension. The tax authorities will impose a penalty for late filing, so it is important to keep a close eye on the deadline.
