Mortgage Interest Deduction in the Netherlands for Expats (2026)
The mortgage interest deduction in the Netherlands for expat homeowners is one of the most important financial advantages of buying property in the country. Many international buyers focus only on house prices and mortgage rates, yet the Dutch tax system significantly lowers the real cost of homeownership. Therefore, understanding how the deduction works can help expats make a better long-term housing decision.
Mortgage interest deduction allows homeowners to subtract mortgage interest payments from their taxable income. As a result, the effective monthly cost of a mortgage becomes lower than the gross payment shown by the bank. This deduction applies only to your primary residence, meaning the property where you actually live. Investment properties or rental homes are not eligible.
However, rules for the Dutch mortgage interest tax deduction have changed over time. The maximum deduction rate has gradually decreased for high-income taxpayers, and several structural requirements now apply to new mortgages. Because of these changes, expats often need a clear explanation before deciding whether buying a home is financially beneficial.

How the Mortgage Interest Deduction in the Netherlands for Expat Buyers Works
The mortgage interest deduction in the Netherlands for expat homeowners works through the Dutch income tax system. When you file your annual tax return, you can subtract mortgage interest payments from your taxable income in Box 1, which covers employment income and housing costs.
Eligible mortgage types
To qualify for the Dutch mortgage interest tax deduction, the mortgage must meet strict requirements. The most important rule is that the mortgage must be repaid using an annuity or linear repayment structure within a maximum period of thirty years. These repayment structures ensure the loan gradually decreases over time.
If you have an older interest-only mortgage from before 2013, different rules may apply. However, most expats purchasing property today use annuity mortgages because lenders structure them to comply with tax rules automatically.

What costs are deductible
Several mortgage-related costs may qualify for a tax deduction. These include:
Mortgage interest payments
Mortgage advisor fees
Property valuation costs
Notary fees related to the mortgage deed
NHG guarantee premium
Because these costs reduce taxable income, they effectively lower the net price of purchasing a home.
Why the deduction matters
For expats earning income in the Netherlands, the expat mortgage tax deduction rules often translate into thousands of euros of tax savings each year. As a result, the real monthly cost of owning property can be significantly lower than renting a comparable home.
Mortgage Interest Deduction Rules for Expats in the Netherlands in 2026
The mortgage interest deduction rules for expats in the Netherlands continue to evolve. Therefore, it is important to understand the 2026 limits and how they affect higher-income households.
Deduction cap for high incomes
The Dutch government gradually reduced the maximum deduction rate over recent years. In 2026, the deduction rate for higher tax brackets remains capped at approximately 36.97%, aligning with the base income tax bracket.
This means high-income taxpayers cannot deduct mortgage interest at the highest tax rate anymore. Instead, they receive a deduction at the capped rate.
Although this change reduced tax benefits compared with older rules, the deduction still provides substantial savings for most homeowners.
Changes introduced in recent years
Several structural reforms affect the deduction:
New mortgages must follow annuity or linear repayment
Interest-only loans generally do not qualify
Maximum deduction rates are gradually reduced
Because of these reforms, calculating net mortgage costs now requires more careful planning.
For official guidance on the capped deduction rate, see the Dutch Tax Authority (Belastingdienst) explanation.
This source explains how tax brackets interact with mortgage interest deductions and how homeowners should report their mortgage details in the annual tax return.
How Expats Claim the Expat Mortgage Tax Deduction in the Netherlands
The mortgage interest deduction in the Netherlands that homeowners claim happens through the annual income tax return filed with the Dutch Tax Authority (Belastingdienst). Most expats submit this tax return online using the national digital tax portal.
Claiming the deduction in practice
When filing your tax return, you must enter:
Mortgage balance
Mortgage interest paid during the year
Property valuation (WOZ value)
Ownership share if multiple buyers exist
The tax system then calculates the deductible amount automatically. Because of this process, homeowners usually receive their tax benefit through a lower annual tax bill or a refund.
Monthly tax advantage option
Some homeowners prefer to receive the tax benefit monthly rather than annually. This can be done by applying for a provisional tax refund, which spreads the deduction throughout the year.
As a result, monthly mortgage costs appear lower immediately.
Interaction with the 30% ruling
Expats receiving the 30% ruling may wonder whether it affects their deduction eligibility. In most cases, the expat mortgage tax deduction rules remain available as long as you are taxed as a resident.
However, the exact effect depends on your tax residency status and personal situation.

When the Dutch Mortgage Interest Tax Deduction Makes Buying Cheaper Than Renting
Understanding the Dutch mortgage interest tax deduction helps expats evaluate the real cost of homeownership compared with renting.
Example scenario
Consider an expat purchasing a home with a €400,000 mortgage at a 4% interest rate. The first-year interest payment could be around €16,000. If the deduction rate is roughly 37%, the tax refund may reach approximately €5,900.
This reduces the effective interest cost significantly.
Long-term financial benefits
Beyond the annual tax savings, homeowners also build equity over time. Therefore, the total financial advantage often includes:
Lower net monthly costs
Property value appreciation
Long-term wealth accumulation
When combined with mortgage repayment, the deduction creates a powerful incentive for long-term residents to buy property.
Nevertheless, buying does not always beat renting. Short stays or unstable employment may still favour renting.
