Mortgage Interest Deduction in the Netherlands: A Guide for Expats

What is Mortgage Interest Deduction (Hypotheekrenteaftrek)?

The mortgage interest deduction allows homeowners in the Netherlands to deduct the interest paid on their mortgage from their taxable income in Box 1 (income from work and home). This effectively reduces the amount of income on which you pay income tax, leading to a lower overall tax bill or a tax refund.

This deduction is a cornerstone of Dutch housing policy, aimed at making homeownership more accessible. However, there are strict conditions that must be met to qualify.

Key Conditions for Eligibility

To be eligible for mortgage interest deduction, your mortgage must meet specific requirements:

• Primary Residence: The property for which you are deducting interest must be your official primary residence. Investment properties or second homes do not qualify.
• Mortgage Type: New qualifying home debt from 1 January 2013 generally has to be repaid at least on an annuity basis within 30 years; a linear schedule can also qualify. Older debt and refinancings can have transitional rules, so an interest-only loan is not assessed solely by the date of the latest contract.
• Registration: You must be registered with the municipality (gemeente) at the address of the property.
• Term Limit: The deduction is generally limited to a maximum period of 30 years.

How the Deduction Works: Provisional Refund vs. Annual Return

There are two main ways to benefit from the mortgage interest deduction:

• Provisional Refund (Voorlopige Teruggave): Many homeowners opt for a monthly provisional refund. The tax authorities estimate your expected tax deduction for the year and pay you a portion back each month, effectively lowering your net monthly housing costs. This requires submitting an application to the Belastingdienst (Dutch Tax and Customs Administration).
• Annual Tax Return: Alternatively, you can claim the full deduction when you file your annual income tax return. This means you pay full taxes throughout the year and receive a larger refund after filing.

In 2026, qualifying mortgage-interest deductions falling in the highest Box 1 band receive relief at at most 37.56%, rather than 49.50%. The high-income adjustment applies where income before deductions exceeds €78,426. In 2025 the corresponding maximum was 37.48%; use the tax year being filed rather than an old illustrative rate.

Impact of the 30% Ruling on Mortgage Interest Deduction

For expats benefiting from the 30% ruling, the mortgage interest deduction has specific interactions:

• Partial Non-Residency Status (Partiële Buitenlandse Belastingplicht): This election was abolished from tax year 2025. Qualifying employees who used the scheme before 2024 may continue through the 2026 return under transitional rules. It affects Box 2 and Box 3, not Box 1. Mortgage-interest relief depends on the normal home-loan conditions, not on having this election.
• Lower Taxable Income: Because a portion of your salary is tax-free under the 30% ruling, your overall taxable income is lower. This means the actual cash benefit from the mortgage interest deduction might be less significant than for someone without the 30% ruling, as you are already paying less income tax.

It's crucial to understand this interaction for your comprehensive financial planning. A mortgage advisor specializing in expat situations can provide clarity on your specific case.

Other Deductible Costs When Buying Property

Besides mortgage interest, certain other costs associated with buying a home are also deductible in the year of purchase:

• Mortgage advisor fees (hypotheekadvieskosten)
• Valuation fees for the mortgage (taxatiekosten)
• Notary fees for the mortgage deed (kosten hypotheekakte)
• Costs for applying for an NHG (Nationale Hypotheek Garantie) mortgage
• Check other charges against the Belastingdienst cost table rather than assuming every bank or purchase fee is deductible.

These one-off costs can add up, and being able to deduct them from your income helps offset the initial expense of buying.
