Leaving the Netherlands: Tax Guide

Tax Obligations When Leaving

Leaving the Netherlands does not end your Dutch tax obligations immediately. Here is what you need to know:

• File a final tax return — You must file a return for the year you leave, covering the period you were a Dutch resident.
• Settle any open assessments — If you owe money from previous tax years, the Belastingdienst will still pursue payment.
• Non-resident obligations may continue — If you retain Dutch income sources (rental property, pension, investments), you may need to file a non-resident return (C-form).
• Keep your DigiD — You may need it to file returns or communicate with the Belastingdienst after leaving.

Partial-Year Filing

In the year you leave, you file an M-form (migration form) as explained in our filing guide. The M-form splits the year into:

• Resident period: From January 1 to your de-registration date — taxed on worldwide income
• Non-resident period: From your de-registration date to December 31 — taxed only on Dutch-source income

The key implications:

1. Tax brackets apply to your annual income, but heffingskortingen may be calculated pro-rata for the resident period.
2. Box 3 tax is calculated on assets held on January 1 — even if you leave on January 2, you owe Box 3 for the full year.
3. Deductions for the resident period (mortgage interest, donations) are fully claimable.

Box 3 on Departure

Box 3 tax has specific rules for departing expats:

• Reference date is January 1 — If you were a resident on January 1 of the tax year, you owe Box 3 tax for that entire year, regardless of when you leave.
• All worldwide assets count — The value of your savings, investments, and property on January 1 determines your Box 3 liability for the year.
• After departure: Once you are a non-resident, only Dutch real estate and Dutch business interests remain in Box 3 (if any).

Tip: If you are planning to leave, consider the timing. Leaving in December versus January can make a full year's difference in Box 3 liability. If your assets were above the threshold on January 1, you owe Box 3 for that year. If you leave before January 1 of the next year, you would not owe Box 3 for the following year.

Tax Item	Leave in December 2026	Leave in January 2027
Box 3 (2027)	✅ No Box 3 for 2027 — not resident on Jan 1	❌ Owe full-year Box 3 for 2027
Box 1 (2027)	✅ No Dutch income tax for 2027 (unless NL-source income)	⚠️ Taxed on Jan 2027 income; M-form required
Heffingskortingen	Pro-rata for 2026 resident months	Pro-rata for 2027 (1 month) — minimal benefit
Health insurance	Cancel from departure date in Dec	Still required for January 2027
30% ruling	Ends Dec 2026 — no carry-over	Extends 1 month into 2027 (if still eligible)

30% Ruling Termination

When you leave the Netherlands, your 30% ruling terminates:

• End date: The ruling ends on your last working day in the Netherlands, or the date you de-register from the gemeentelijke basisadministratie (GBA), whichever is earlier.
• No carry-over: Unused months cannot be transferred or saved for a future period.
• Re-entry: If you return to the Netherlands later, you may re-apply for the ruling, but the duration will be reduced by your previous period of use.

De-registration Checklist

Before leaving the Netherlands, complete these steps to avoid tax complications:

1. De-register at the gemeente — Visit your local municipality and register your emigration (vertrek naar het buitenland). This updates your BRP record and sets your departure date.
2. Notify your employer — They need to adjust payroll, end the 30% ruling, and prepare your final jaaropgaaf.
3. Close or update bank accounts — Notify Dutch banks of your emigration. Decide whether to keep a Dutch account for any remaining refunds.
4. Cancel your health insurance — You can cancel Dutch health insurance (zorgverzekering) from your departure date. Request a confirmation letter.
5. Update Belastingdienst records — Ensure your new foreign address is on file. Refunds and correspondence will be sent there.
6. Keep your DigiD — Maintain access for filing your final return and receiving assessments. See our DigiD guide.
7. Collect all documents — Gather your final jaaropgaaf, bank statements (January 1 balances), and any deduction receipts before leaving.

Tax Treaty Considerations

The Netherlands has tax treaties with over 90 countries to prevent double taxation. Key considerations:

• Income earned during NL residence: Taxed in the Netherlands regardless of where your employer is based.
• Pension income: Depending on the treaty, Dutch pension income may be taxed in the Netherlands, your new country of residence, or split between both.
• Rental income from NL property: Generally remains taxable in the Netherlands even after you leave.
• Investment income: Tax treatment depends on the specific treaty between the Netherlands and your new country.

Frequently Asked Questions

How long do I have to file my final Dutch tax return?

The standard deadline is May 1 of the year after the tax year. For example, if you leave in 2026, file by May 1, 2027. You can voluntarily file up to 5 years after the tax year.

Will I still receive my Dutch pension (AOW)?

AOW pension rights are built up for each year you lived and worked in the Netherlands (2% per year). You can receive AOW payments abroad when you reach the retirement age. The amount depends on how many years you contributed.

What about my Dutch mortgage?

If you sell your Dutch home before leaving, any capital gains on your primary residence are exempt from tax. If you keep the property, mortgage interest may no longer be deductible as a non-resident (unless the property becomes a rental, which moves it to Box 3).

Can I claim a refund after leaving?

Yes. Many departing expats are owed refunds due to over-withholding in their departure year. File your M-form to claim it. You can file up to 5 years after the tax year.

Do I need a Dutch tax advisor after leaving?

If your only remaining obligation is a final tax return with straightforward employment income, you can likely file it yourself. If you have ongoing Dutch income sources, pension rights, or complex assets, professional advice is recommended.
