The start of a new year isn’t just about New Year’s resolutions, it’s also the time to think about resolving your income tax return. In the Netherlands, the fiscal year runs from January 1 to December 31. Around the first week of February the tax authorities begin sending notifications reminding you to submit your Dutch income tax return. If you didn’t receive an invitation, be sure to double check with the tax authority, as it is your own responsibility to submit your tax return on time. In general, your Dutch tax return must be submitted before May 1. If you submit your return before April 1, then you can expect a tax assessment concerning your return before July 1.
