A Clear Timeline: What to Do Before and After 1 March
Filing a Dutch tax return may feel unfamiliar, especially if you have recently relocated. The tax return period opens on 1 March, but preparation should start earlier.
Use this simple timeline to guide you.
February: Prepare in Advance
- Check whether you need to file. You are required to file a tax return if you receive an official letter from the Belastingdienst.
You may also need to file a tax return if one or more of the following situations apply:
- You arrived in or left the Netherlands during the tax year
- You had income from multiple sources
- You have savings or assets above the tax-free threshold
If you are unsure whether you are required to file, it is advisable to check your situation with a tax professional. Many expats are entitled to a refund, even if filing is not strictly mandatory.
2. Arrange your DigiD
Before you can file your tax return, you must have access to DigiD.
DigiD is required to log in to the Mijn Belastingdienst portal.
Without it, you cannot submit your tax return online.
If you do not yet have a DigiD:
- Apply as soon as possible
- Allow time for activation
- Ensure your login details are working before March
For anyone living and working in the Netherlands, DigiD is essential.
3. Gather your documents
Make sure you have the following ready:
- Annual income statement (jaaropgave) from your employer
- BSN (citizen service number)
- DigiD login details
- Information about foreign income (if applicable)
- Details about savings, investments or property
- Housing information if relevant
Preparing these documents in February prevents stress later.
