Apply for the Dutch Tax Identification number (BSN)

A BSN is a unique, personal number that is required for all governmental or official matters in the Netherlands. If you will live in the Netherlands for more than four months you will need to register as a resident of the Netherlands with the Dutch civil register. This registration needs to be completed at the Town Hall or the Expatcenter of the Dutch municipality where you will live.

When registering with the Dutch civil register you will need to confirm your personal details and home address. All the following documents are required:

  • A valid passport
  • Valid residence authorization for the Netherlands through either a residence permit card, a residence endorsement passport sticker, or an EU/EEA or Swiss passport
  • A signed rental contract or property ownership document of your place of residence
  • A birth certificate and, if applicable, marriage, divorce and/or name change certificates. The certificate(s) may need to be legalized and translated

After the registration is completed, a BSN will be issued by the Dutch municipality.

From the end of the tax year

We’re very pleased to confirm that we will be supporting you with the preparation of your Dutch tax return.

Following the end of the tax year in December, we will contact you to ask you to complete your About Me Questionnaire. This is an online questionnaire which, when filled out, should give us all the information we need to complete your tax return.

The questionnaire can be accessed via the GA Portal. Click here for an overview of the About Me Questionnaire and how to complete it.

The sooner you can submit your information, the sooner we can make a start on your tax return. We'll let you know once it is complete so you can approve it, if you’re ready to do so, via the GA Portal.

What do I need to do by May 1?

Submit Your Tax Return

The deadline each year for submitting tax returns to the Dutch tax authorities is 1 May after the end of the tax year.

There are penalties for late filing of your tax return so it's very important you remember this date.

If Deloitte is supporting with the preparation of your tax return, in general we will extend the filing deadline for an additional year but this may result in additional interest charges on any balance due.

Within approximately 3-6 months after the filing of the tax return the Dutch tax authorities will respond with a (preliminary) tax assessment.

Tax return filing deadline

Tax returns for resident taxpayers must be filed with the tax authorities before 1 May of the year following the tax year. For non-resident taxpayers and for resident taxpayers who did not reside in the Netherlands for the full calendar year, the filing deadline is 1 July. It is common practice for taxpayers with a tax advisor to apply to extend the tax return filing deadline.
