We’ll update them when it publishes the figures for 2026. ## How to find your own deadline Most people get a letter from the tax office (an aangiftebrief) asking them to file. Your deadline is the date in that letter. You can also find it in Mijn Belastingdienst, where you log in with DigiD. If you didn’t get a letter, check whether you have to file anyway. You do if you have to pay tax, for example because too little tax was taken from your income during the year. ## How to get more time - **Ask before your deadline.** Your request must reach the tax office before the date in your letter. A request that arrives late isn’t accepted. - **Do it online or on paper.** If you received a letter, you can ask online in Mijn Belastingdienst. There is also a paper form. - **Partners ask separately.** If you have a fiscal partner, they need to make their own request. **An extension can cost interest.** If you end up owing tax, you usually pay tax interest (belastingrente) over the extra time. ## What happens if you’re late - **A reminder.** After your deadline, the tax office sends a reminder (herinnering). - **A formal demand.** If you still don’t file, you get a demand (aanmaning). Your return must then arrive within 10 working days. - **A fine.** After that, the tax office can give you a fine. It currently states €469, rising to as much as €6,709 if it happens again. It can also stop a provisional assessment or allowances. - **An estimate.** If you never file, the tax office estimates your income and sends you a tax bill based on that estimate. ## Get ready before March Your yearly statements usually arrive in January and February. Collect them as they come in, so you can file soon after 1 March. Our [document checklist](https://taxpress.co/document-guide) shows what to look for. Preparing your return with Taxpress doesn’t send it and doesn’t extend your deadline. You still need to make sure it reaches the tax office in time, or ask for an extension.

From 1 March 2027. Most people must file before 1 May 2027, or the date in their letter. ### Can I get an extension? Yes, if you ask before your deadline. With an extension you usually have until 1 September 2027. You may pay tax interest if you end up owing tax. ### Is the deadline different if I moved to or from the Netherlands? Yes. The return for the year you moved has its own dates. For 2025, it could be filed from 1 May until 1 July 2026. Check the date in your letter. [More about the year you moved](https://taxpress.co/tax-return/m-form). ### What if I miss the deadline? You first get a reminder, then a formal demand. If you still don’t file in time, you can get a fine. File as soon as you can. ### Does preparing my return with Taxpress count as filing? No. Your return counts as filed only once it has been sent to the tax office. Nothing is sent without your approval. ## Sources we checked We checked this page against these official sources on 10 November 2026. The tax office publishes new dates and amounts each year.
