Dutch tax return for 2026 – how to prepare? Document checklist πŸ“‹

26 October 2026 ExpressTax

Did you work in the Netherlands in 2026? πŸ‡³πŸ‡±
Good news – there’s a real chance a tax refund is waiting for you πŸ’°

You’ll file your 2026 tax return at the start of 2027. But it pays to prepare right now – so in January you’re not digging through drawers, inboxes and old addresses πŸ˜„

Here’s a practical checklist: what to collect, what to ask for and what to watch out for πŸ‘‡


The most important document: Jaaropgave 2026 from ALL your employers πŸ“„

A jaaropgave is your annual income statement. Without it, your tax return can’t be done correctly.

It shows, among other things:

  • your total gross income for 2026
  • the tax withheld (loonheffing)
  • the tax credit applied (heffingskorting)
  • your employment period and employer details

πŸ‘‰ Important: you need a jaaropgave from every employer and every agency you worked for in 2026. Even if it was only 2 weeks.

Missing even one jaaropgave = income under-reported. That’s a fast track to a correction and paying money back to the tax office 😬

When will you get your jaaropgave 2026?

Employers and agencies usually issue it in January or February 2027. Most often:

  • in the employment agency’s app or portal
  • by email as a PDF
  • by post to the address your employer has on file

πŸ’‘ Tip: check now that you still have access to each agency’s portal and that your employer has your current address and email. Access often expires after you change jobs.

πŸ’‘ The layout of a jaaropgave differs per employer, but the field names are almost always the same.


Received benefits from UWV? You also need the UWV jaaropgave πŸ₯

If you received money from UWV in 2026, for example:

  • unemployment benefit (WW),
  • sickness benefit (Ziektewet),
  • incapacity benefit (WIA / WGA),

…then UWV is just another β€œemployer” for the tax office. It issues its own UWV jaaropgave 2026 – and that has to be included in your tax return too.

πŸ‘‰ You’ll find it in Mijn UWV (log in with DigiD), or it will arrive by post.


No permanent registration in the Netherlands? Your income from other countries matters 🌍

This is often the point that decides how much money comes back to you.

If you weren’t permanently registered in the Netherlands (e.g. you lived in your home country and came to the Netherlands to work), you usually file as a non-resident taxpayer.

In that case the tax office also looks at whether you earned money outside the Netherlands. If at least 90% of your income comes from the Netherlands, you can get the same tax credits as Dutch residents. That often means a noticeably bigger refund πŸ’Έ

That’s why an income statement is worth getting

If in 2026 you had no income outside the Netherlands (or very little), it’s best to have proof:

πŸ“„ Best option: the Belastingdienst form Inkomensverklaring EU/EER 2026 (Income Statement EU/EEA), confirmed and stamped by the tax office in your country of residence

πŸ“„ Or: an official income certificate for 2026 from the tax office in your country of residence

Since 2026 the Belastingdienst doesn’t always require this document upfront – but it can ask for it, and then your payout is put on hold. Better to have it ready and avoid the stress πŸ˜‰

πŸ‘‰ Your home tax office usually issues the 2026 certificate only after you’ve filed your 2026 tax return there. Not sure what exactly to request? We’ll tell you.


Update your address at the Belastingdienst – seriously, it matters πŸ“¬

The Belastingdienst sends all letters to the address it has on file: assessments (aanslag), requests for documents, payment demands, toeslagen information.

If they still have your old address – e.g. agency housing you’ve already moved out of – the letters get lost. And the deadlines keep running ⏳

How to update your address?

  • You live in the Netherlands and are registered (BRP) – report your move to the municipality (gemeente) and the Belastingdienst gets your new address automatically.
  • You live outside the Netherlands – change your address via MyRNI (with DigiD), at an RNI desk, or with the β€œAdreswijziging doorgeven Buitenland” form sent to the Belastingdienst.
  • Want letters sent somewhere else? You can register a postal address (postadres).

πŸ’‘ An address change usually takes up to about 10 working days – so do it before you file, not after.


Other important things for your 2026 tax return βœ…

  • BSN – your Dutch tax number. It’s on your jaaropgave, payslips and contract.
  • DigiD – check that it still works. You need it for Mijn UWV, MyRNI and Mijn Belastingdienst.
  • Dates of stay and registration – when you arrived and when you deregistered (if you were registered at all).
  • Partner and children – if you have a spouse or partner, their income can also affect the size of your refund.
  • Health insurance and zorgtoeslag – if you received healthcare allowance in 2026, it will be settled afterwards based on your actual income. Better to know early whether you’ll get money back or have to repay.
  • Letters from the Belastingdienst – keep them all (e.g. voorlopige aanslag). They often contain important deadlines.
  • Previous years – you can reclaim tax up to 5 years back. It’s not too late for 2021–2025 either πŸ˜‰

FAQ: Dutch tax return for 2026 ❓

Can I file my 2026 tax return as early as January 2027?

Yes. If you already have your jaaropgave 2026, you can apply online with ExpressTax in January and see your refund amount straight away.

What if my employer doesn’t send me a jaaropgave?

First ask the agency office or check its portal. If that doesn’t help – contact us. We can often recover the data.

Do UWV benefits have to be included in the tax return?

Yes. UWV benefits (e.g. WW or Ziektewet) are income on which tax was withheld. You need the UWV jaaropgave.

Why do I need an income certificate from my home country?

If you weren’t permanently registered in the Netherlands, the certificate shows that (almost) all your income came from the Netherlands. That way you can get the same tax credits as a resident – which often means a bigger refund.
