Do you still have to file taxes if you are an expat?

Russell Advocaten · 30 aug 2026

Yes, expats living and working in the Netherlands are generally required to file a tax return, even if income tax is withheld from their salary by their employer. The obligation depends primarily on your tax residency status and the nature of your income. The sections below address the most common questions expats in the Netherlands have about their tax filing obligations.

Who counts as a tax resident in the Netherlands?

You are a tax resident of the Netherlands if the Netherlands is your permanent home, based on your personal and economic ties to the country. Tax residency is not simply a matter of where you hold a passport or where your employer is based, Dutch tax authorities assess the totality of your circumstances, including where you live, where your family resides, and where your assets and social connections are centred.

In practice, most expats who relocate to the Netherlands to take up employment become Dutch tax residents from the moment they establish their primary residence here. This means they are subject to Dutch income tax on their worldwide income, covering earnings, savings, investments, and income from substantial shareholdings.

It is worth noting that the Netherlands uses a box system for income tax:

Box 1 covers income from work and home ownership, taxed at progressive rates.
Box 2 covers income from a substantial interest in a company (generally a shareholding of 5% or more).
Box 3 covers income from savings and investments, based on a deemed return on assets.

Whether a tax treaty between the Netherlands and your home country affects this assessment is a separate question, but the starting point is always establishing your residency status correctly.

What taxes are expats required to pay in the Netherlands?

Expats who are tax residents of the Netherlands are required to pay income tax on their worldwide income across all three boxes described above. In addition, they are liable for national insurance contributions, which fund state pension, survivor benefits, and long-term care. These contributions are typically collected alongside income tax through the wage tax system.

For expats in employment, wage tax is withheld at source by the employer each month. However, wage tax is a prepayment, it does not replace the annual income tax return. Additional income, deductible costs, or adjustments such as the 30% ruling (discussed below) may affect the final amount owed or the refund due.

Expats who own property in the Netherlands may also be subject to real estate transfer tax when purchasing a home, as well as municipal property tax on an ongoing basis. Those renting a house in the Netherlands as an expat are not directly liable for property taxes, but should be aware that their landlord’s tax position can influence rental terms and conditions.

Do expats have to file a tax return if tax is already withheld?

Yes, expats in the Netherlands generally need to file an annual income tax return even if wage tax has already been withheld from their salary. Wage tax withheld by an employer is a preliminary levy, the annual return reconciles this against your actual tax liability for the full year, taking into account all sources of income, deductions, and applicable schemes.

There are situations where filing is particularly important for expats:

You have income from multiple sources — for example, rental income, foreign dividends, or freelance earnings alongside your employment income.
You are eligible for deductions — such as mortgage interest on a Dutch property or certain personal deductions.
You use the expat scheme (30% ruling) — the ruling affects your taxable income and must be reflected correctly in your return.
You have assets or savings above the threshold — Box 3 income from savings and investments must be declared annually.
You moved to or from the Netherlands during the tax year — a partial-year return (the M-form) is required in the year of arrival or departure.

Even where filing is not strictly mandatory, submitting a return is often worthwhile, as it may result in a refund of excess wage tax withheld.

What is the 30% ruling and how does it affect tax obligations?

The 30% ruling, now formally called the expat scheme, is a tax facility that allows qualifying employers to pay a portion of a foreign employee’s salary tax-free, compensating for the additional costs of relocating to and living in the Netherlands. For expats in the Netherlands who qualify, it can significantly reduce the effective tax burden on employment income.

Under the scheme, the tax-free allowance was historically set at 30% of gross salary. However, the scheme has been subject to ongoing reform. For employees who became eligible after 1 January 2024, the maximum tax-free percentage will be reduced to 27% as of 1 January 2027. In 2026, the maximum untaxed allowance is capped at a salary-linked ceiling, employees earning EUR 262,000 or more can receive a maximum untaxed allowance of EUR 78,600 for the full year, subject to the Balkenende norm on maximum remuneration.

The scheme also affects Box 2 and Box 3 obligations. Since 1 January 2025, expats using the scheme can no longer apply for partial foreign tax liability. Before that date, they were treated as foreign taxpayers for Box 2 and Box 3 purposes, meaning foreign capital income in those boxes was not taxable in the Netherlands. From 2025 onwards, expats must declare their income from substantial interest and their savings and investments held in the Netherlands in their annual return.

To qualify for the expat scheme, the employee must:

Be in salaried employment with a Dutch employer.
Possess specific expertise that is scarce in the Dutch labour market, demonstrated by meeting the applicable minimum salary threshold (EUR 48,013 in 2026 for most employees; EUR 36,497 for those under 30 with a qualifying master’s degree).
Have lived more than 150 kilometres from the Dutch border for more than 16 of the 24 months prior to their first working day in the Netherlands.
Have the employer obtain a formal approval decision (beschikking) from the Dutch Tax Administration within four months of the employee’s first working day.

The scheme runs for a maximum of five years. Changing employers does not automatically transfer the arrangement, a new application may be required, although transitional rules apply when the move occurs within three months and the new employer submits an application within four months of the first working day.

How does a tax treaty affect an expat’s filing obligations?

A tax treaty between the Netherlands and an expat’s home country can affect which country has the right to tax specific types of income, and may reduce or eliminate double taxation. However, a tax treaty does not automatically remove the obligation to file a Dutch tax return, it changes how income is taxed, not whether it must be declared.

The Netherlands has concluded tax treaties with a large number of countries. These agreements typically allocate taxing rights based on criteria such as where employment is exercised, where a company is resident, and where real estate is situated. For example, income from employment carried out in the Netherlands is generally taxable in the Netherlands, regardless of where the employer is incorporated.

Where a treaty grants the Netherlands the right to tax certain income, that income must be reported in the Dutch return. Where a treaty allocates taxing rights to the other country, the Netherlands may still require the income to be declared but will provide an exemption or credit to avoid double taxation. The specific mechanism depends on the treaty in question and the nature of the income involved.

Expats with income in multiple jurisdictions, or those who split their time between countries, face particularly complex filing positions. The interaction between treaty provisions, Dutch domestic rules, and the expat scheme requires careful analysis in each individual situation.

When should an expat seek legal or tax advice in the Netherlands?

Expats in the Netherlands should seek professional advice whenever their tax or legal position involves complexity beyond straightforward single-employer employment income. While routine wage tax is handled by the employer, a number of circumstances make professional guidance important.

Key situations where advice is advisable include:

Applying for or reviewing eligibility for the expat scheme (30% ruling), particularly given the ongoing legislative changes affecting the scheme from 2024 onwards.
Arriving in or departing from the Netherlands during a tax year, which triggers a partial-year return with specific rules.
Holding assets, investments, or shareholdings abroad that may fall within Dutch Box 2 or Box 3 obligations.
Changing employers and needing to assess whether the expat scheme can be transferred or a new application is required.
Navigating the interaction between a home-country tax treaty and Dutch filing requirements.
Questions arising from renting or purchasing property in the Netherlands as an expat, where both tax and tenancy law considerations apply.

The expat scheme rules have changed significantly since the original 30% ruling was introduced, and further changes are planned. Relying on outdated information can lead to missed entitlements or unintended tax exposure. Consulting a qualified adviser ensures your position reflects the current rules and your specific circumstances.

Veelgestelde vragen

What is the deadline for filing a Dutch income tax return as an expat?

The standard deadline for filing a Dutch income tax return is 1 May of the year following the tax year in question (so 1 May 2026 for the 2025 tax year). However, expats can request an extension, and if you use a registered tax adviser, they can typically obtain an extended deadline on your behalf — sometimes as late as the following year. Filing on time is important to avoid penalties and interest charges from the Dutch Tax Administration (Belastingdienst).

What is the M-form and do I need to file one?

The M-form (Migratieformulier) is a special version of the Dutch income tax return required in the year you arrive in or depart from the Netherlands. It covers a partial tax year and requires you to split your income and assets between the period you were and were not a Dutch tax resident. The M-form is more complex than the standard return and cannot currently be filed digitally through the standard Belastingdienst portal, so most expats benefit from professional assistance when completing it.

Can I lose eligibility for the 30% ruling if I change jobs?

Yes, changing employers can interrupt or end your 30% ruling if the transition is not handled correctly. The ruling is tied to your employment relationship with a specific employer, so when you switch jobs, your new employer must submit a fresh application to the Dutch Tax Administration within four months of your first working day at the new company. If the job change happens within three months of leaving your previous employer, transitional rules may allow continuity — but this is not automatic, and gaps in coverage can result in losing the benefit entirely.

Do I need to declare foreign bank accounts and assets in my Dutch tax return?

Yes. As a Dutch tax resident, you are required to declare your worldwide assets — including foreign bank accounts, investment portfolios, and real estate — under Box 3 of the Dutch income tax return, provided your net assets exceed the applicable threshold (€57,684 per person in 2025). The Netherlands participates in the Common Reporting Standard (CRS), which enables automatic exchange of financial account information between countries, so undeclared foreign assets carry a real risk of detection and penalties.

What happens if I don't file a Dutch tax return?

Failing to file a required Dutch tax return can result in a default assessment (ambtshalve aanslag) issued by the Belastingdienst, often based on estimated figures that may be higher than your actual liability. In addition, the tax authorities can impose administrative fines for late or non-filing, and persistent non-compliance can lead to criminal prosecution in serious cases. Even if you believe you owe no additional tax beyond what was withheld, failing to file can mean missing out on legitimate refunds and deductions.

I'm a freelancer or self-employed expat in the Netherlands — does my tax situation differ from an employed expat?

Yes, significantly. Self-employed expats (ZZP’ers) are not subject to wage tax withholding at source, meaning they must make their own provisional tax payments and file an annual return covering their business income. They may also be liable for VAT (BTW) registration and quarterly filing obligations. Importantly, self-employed individuals are not eligible for the 30% ruling, which is exclusively available to those in salaried employment with a Dutch employer — so the tax planning landscape for freelancers is quite different.

How do I know whether the Netherlands or my home country has the right to tax my foreign pension or investment income?

The answer depends on the specific tax treaty between the Netherlands and your home country, as different treaties allocate taxing rights over pensions, dividends, and capital gains differently. For example, some treaties give the source country the exclusive right to tax pension income, while others assign that right to the country of residence. You should obtain the specific treaty text and, ideally, professional advice to determine your position — because even where your home country retains taxing rights, the Netherlands may still require you to declare the income in your Dutch return and apply an exemption or credit.
