Across Europe, most people must file an annual income tax return. This allows the tax authorities to check how much income you earned and whether you paid the correct amount of tax on it. In this lesson, we focus on how this works in the Netherlands.

Why do I have to file a Dutch income tax return?

Every spring, many people in the Netherlands log in to the website of the Dutch tax authorities (Belastingdienst) to complete their income tax return (aangifte inkomstenbelasting).

Filing your return is essentially your moment to inform the Belastingdienst about:

• Your income in the previous year

• Your assets and other relevant financial details

Based on this information, the tax authorities determine how much tax you owe — or whether you’ve paid too much. Many details are already pre-filled. The Belastingdienst receives information from sources such as your employer and your bank. In most cases, you mainly need to check whether the information is correct. You can usually file your return between March and May.

Is filing a tax return mandatory in the Netherlands?

Filing a Dutch income tax return is not mandatory for everyone. If you receive an official letter asking you to file a return (aangiftebrief), you know you’re required to submit one. Failing to file after receiving this letter can result in a fine. These letters are usually sent in January or February. If you didn’t receive a letter, you can check your online account via “Mijn Belastingdienst” under “Inkomstenbelasting” to confirm whether you have been invited to file.

If you have not received a letter, you’re generally not required to file a return. However, it can still be worthwhile as you could be entitled to a tax refund.

How do tax returns work in the Netherlands?

In many cases, tax is withheld in advance. For example, if you are employed, your employer withholds income tax from your salary each month and transfers it to the Belastingdienst.

Sometimes you end up paying more tax than necessary. By filing your income tax return, you can check whether you are entitled to a refund and request the amount back.

It’s also possible that you have paid too little and need to pay additional tax.

Takeaways

• In the Netherlands, you can usually file your income tax return between March and May.

• Filing is mandatory if you receive an official invitation letter.
