The Netherlands offers one of the most generous mortgage interest deduction systems in Europe. Known as hypotheekrenteaftrek, this tax benefit allows Dutch homeowners to deduct mortgage interest payments from their taxable income, potentially saving thousands of euros annually.
This guide explains how the Dutch mortgage tax deduction works in 2026, who qualifies, what has changed, and how to maximize your tax savings.
What Is Hypotheekrenteaftrek?
Hypotheekrenteaftrek (mortgage interest deduction) allows Dutch homeowners to deduct the interest paid on their mortgage from their taxable income in Box 1 of the Dutch income tax system. This effectively reduces your income tax bill by your marginal tax rate multiplied by the deductible interest amount.
For example, if you pay €10,000 in mortgage interest annually and your marginal tax rate is 36.97%, you save approximately €3,697 in income tax.
Who Qualifies for Mortgage Interest Deduction?
To qualify for hypotheekrenteaftrek in 2026, you must meet several conditions:
- Owner-occupied residence: The property must be your primary residence (eigen woning). Investment properties and second homes do not qualify.
- Mortgage type: Only annuity and linear mortgages qualify for new loans taken after January 1, 2013. Interest-only mortgages no longer qualify for new loans.
- Loan purpose: The mortgage must be used to purchase, build, or improve your primary residence.
- Registration: The mortgage must be registered with the Dutch Land Registry (Kadaster).
Qualifying Mortgage Types
Annuity Mortgage (Annuïteitenhypotheek)
With an annuity mortgage, you pay a fixed monthly amount that includes both interest and principal repayment. In the early years, most of your payment goes toward interest, maximizing your tax deduction. Over time, the interest portion decreases as the principal is paid down.
Linear Mortgage (Lineaire hypotheek)
With a linear mortgage, you repay a fixed amount of principal each month, plus interest on the remaining balance. Your total monthly payment decreases over time as the interest portion shrinks. This results in a gradually decreasing tax deduction.
Interest-Only Mortgages (Aflossingsvrije hypotheek)
Interest-only mortgages taken before January 1, 2013, still qualify for full mortgage interest deduction. However, new interest-only mortgages do not qualify for hypotheekrenteaftrek. If you have a pre-2013 interest-only mortgage, you can continue deducting the interest, but you must repay the full principal at the end of the term.
How Much Can You Deduct?
The amount you can deduct depends on your marginal tax rate and the interest you actually pay:
| Tax Bracket (2026) | Marginal Rate | Effective Deduction on €10,000 Interest |
|---|---|---|
| First €75,518 of taxable income | 36.97% | €3,697 |
| Above €75,518 | 49.50% | €4,950 |
The deduction is applied against your Box 1 income (income from work and homeownership). If your mortgage interest exceeds your Box 1 income, the excess can be carried forward to future years or, in some cases, carried back to previous years.
The Eigenwoningforfait (Imputed Rental Value)
While you can deduct mortgage interest, you must also add the eigenwoningforfait (imputed rental value) to your taxable income. This is a notional rental income that the tax authorities assume you receive from owning your home.
The eigenwoningforfait is calculated as a percentage of the WOZ value (municipal property valuation):
- WOZ value up to €1,200,000: 0.35% of WOZ value
- WOZ value above €1,200,000: 2.35% on the excess
For a home with a WOZ value of €400,000, the eigenwoningforfait would be €1,400 per year (0.35% × €400,000). This amount is added to your taxable income, partially offsetting the mortgage interest deduction.
Changes to Mortgage Interest Deduction in 2026
The Dutch government has been gradually reducing the mortgage interest deduction rate for higher-income earners. The key changes for 2026:
Phased Reduction for High Incomes
The maximum deductible rate for mortgage interest is being phased down from the historical 52% to 36.97% for most taxpayers. This reduction is being implemented gradually:
- 2023: 45.83%
- 2024: 43.50%
- 2025: 40.30%
- 2026: 37.10% (approaching the first bracket rate of 36.97%)
By 2026, the maximum deduction rate will be nearly aligned with the first tax bracket rate, significantly reducing the benefit for high-income homeowners.
Transferability Between Partners
If you are married or in a registered partnership, you can transfer unused mortgage interest deduction to your partner, provided you file a joint tax return. This can be particularly beneficial if one partner has little or no Box 1 income.
Strategies to Maximize Your Mortgage Interest Deduction
1. Choose the Right Mortgage Type
If you are taking out a new mortgage, choose between annuity and linear based on your financial situation:
- Annuity: Higher initial tax deduction, fixed monthly payments, better for cash flow management
- Linear: Decreasing tax deduction over time, lower total interest paid, better for long-term savings
2. Time Your Mortgage Payments
If you have flexibility in when you make extra principal payments, consider the tax implications. Paying down principal reduces your future interest payments and therefore your future tax deduction. In some cases, it may be more beneficial to invest extra funds rather than pay down the mortgage early.
3. Use the Mortgage Interest Deduction for Home Improvements
Interest on loans taken to improve your primary residence is also deductible. This includes renovations, extensions, and energy-efficient upgrades. Keep all receipts and ensure the work is properly documented.
4. Consider the NHG (National Mortgage Guarantee)
The NHG provides a government guarantee on mortgages up to a certain amount (€435,000 in 2026). While this does not directly affect your tax deduction, it typically results in lower interest rates, reducing your overall mortgage costs.
Filing Your Tax Return with Mortgage Interest Deduction
Mortgage interest deduction is claimed on your annual Dutch income tax return (aangifte inkomstenbelasting). Your mortgage provider will send you an annual statement (jaaropgave) showing the total interest paid during the year.
Key steps:
- Obtain your jaaropgave from your mortgage provider (usually available by January)
- Enter the total interest paid in Box 1 of your tax return
- The tax authorities will calculate your deduction based on your marginal tax rate
- If you have multiple mortgages or properties, ensure each is correctly reported
The filing deadline is typically May 1 of the year following the tax year, though extensions are available upon request.
Common Mistakes to Avoid
- Not reporting the eigenwoningforfait: Forgetting to include the imputed rental value in your taxable income can result in penalties.
- Claiming deduction on non-qualifying mortgages: Interest-only mortgages taken after 2013 do not qualify. Ensure your mortgage type is eligible.
- Mixing personal and business use: If you work from home, only the residential portion of the mortgage interest is deductible. Business use must be separated.
- Not keeping proper records: Maintain all mortgage statements, jaaropgaven, and documentation of home improvements for at least seven years.
Frequently Asked Questions
Can I deduct mortgage interest on a second home?
No. Hypotheekrenteaftrek only applies to your primary residence (eigen woning). Interest on mortgages for second homes, vacation properties, or investment properties is not deductible.
What happens if I sell my home?
When you sell your home, the mortgage interest deduction ends. Any remaining mortgage must be repaid from the sale proceeds. If you buy a new primary residence, you can start claiming the deduction on the new mortgage.
Can I deduct mortgage interest if I rent out part of my home?
If you rent out a portion of your home (such as a room), you must allocate the mortgage interest between personal and rental use. Only the personal portion is deductible as hypotheekrenteaftrek. The rental portion may be deductible as a business expense.
Does the mortgage interest deduction apply to expats?
Yes, expats who are Dutch tax residents and own a primary residence in the Netherlands can claim hypotheekrenteaftrek. The rules are the same as for Dutch nationals. If you are a non-resident owning property in the Netherlands, different rules may apply.
