What documents are required to file a tax return from the Netherlands?

12 March 2026 ExpressTax

The most important documents are those that confirm your employment and income.
The Dutch tax authority simply needs to know:

πŸ‘‰ Where did you work?
πŸ‘‰ How much did you earn?
πŸ‘‰ How much tax was withheld?

The annual statement is essential

Most of the time, we only need these things:

πŸ“„
(annual earnings statement) β€” an annual summary of earnings provided by your employer.

There you’ll find:

  • total income
  • tax collected
  • premiums
  • employer information

πŸ‘‰ If you’ve worked at several places, you’ll need all your jaaropgaves.

πŸ“„ Other documents

All you need to do is:

  • photo from a phone
  • scan

It’s only needed to verify your identity.

πŸ“„ IBAN account number

The tax refund is deposited into this account πŸ’°

It could be:

  • Polish account
  • foreign account
  • foreign currency account

πŸ“„ BSN number (Dutch tax ID number)

This is your identification number in the Netherlands.
If you’ve worked legally, you probably already have it.

You can find it, among other places, at:

  • employment contract
  • pay stubs
  • annual statement

πŸ‘‰ Can’t remember the number? Don’t worryβ€”we can often find it in our documents.

You:

  • Get money fast πŸ’°
  • You don’t read Dutch letters πŸ“¬
  • you don’t stress about deadlines

We:

  • We’ll take care of the paperwork πŸ“‘
  • we take the risk ourselves
  • We’ll “deal with” the government for you πŸ˜„

Sometimes you also need additional documents πŸ“‘ πŸ€”

In some cases, the agency may require a few additional items.

Most often, it is:

πŸ“„ EU/EEA Certificate from a Polish tax office

This applies to individuals who wish to file their taxes as EU tax residents.
This often allows you to receive a larger tax refund.

But don’t worryβ€”if necessary:

πŸ‘‰ We’ll tell you all about it
πŸ‘‰ We’ll show you how to get them


πŸ“„ Pay stubs (Salaris / Loonstrook)

They aren’t always necessary, but sometimes they help when:

I need to check something

The annual statement is missing

The employer did not send the documents


Don’t have all your documents? That’s normal πŸ˜„

Very often, people:

  • They lost their annual statement
  • have no contact with their employer
  • worked through an agency
  • They changed their phone number or address

Take it easy.

πŸ‘‰ In many cases, we can help you recover your documents.

It’s part of our job.
