What This Guide Covers

Owning a home in the Netherlands comes with a significant tax benefit that many homeowners especially expats do not fully understand or claim correctly. The Dutch mortgage interest deduction (hypotheekrenteaftrek) allows you to subtract the interest you pay on your home loan from your taxable income, directly reducing how much income tax you owe. But the rules changed again in 2026, and the deduction is being gradually phased out for higher earners.

This complete guide explains exactly how the mortgage interest deduction works in the Netherlands in 2026: who qualifies, what the current deduction rate is, how the eigenwoningforfait (notional rental value) affects your benefit, how to claim it through your tax return, and how much tax you can actually save with worked examples using real 2026 figures.

What Is the Mortgage Interest Deduction (Hypotheekrenteaftrek)?

The hypotheekrenteaftrek — literally “mortgage interest deduction” is a Dutch tax rule that allows homeowners to deduct the annual interest they pay on their mortgage from their Box 1 taxable income (income from work and home ownership).

Because your taxable income is reduced, you end up paying less income tax. The Dutch government originally introduced this benefit to encourage homeownership, and while it is being gradually phased out for high earners, it remains one of the most valuable tax benefits available to homeowners in the Netherlands.

Mortgage Interest Deduction Rate in 2026

This is the most important number for 2026:

In 2026, mortgage interest and all other deductible expenses for owner-occupied housing are maximally deductible at a rate of 37.56%.

This means that regardless of your income tax bracket even if you pay the top rate of 49.5% you can only claim mortgage interest as a deduction at the capped rate of 37.56%.

Why Is the Rate Capped?

Since 2020, the phase-out of the mortgage interest deduction has been accelerated to three percent per year. From 2023, the mortgage interest deduction rate is linked to the rate of the lowest income bracket.

This means that homeowners with an income above €79,137 in 2026 receive a lower benefit than they did under the old rules. Lower-income homeowners are less affected, as they already deduct at the lower rate.

Who Qualifies for the Mortgage Interest Deduction in the Netherlands?

Not every mortgage automatically qualifies for the deduction. You must meet all of the following conditions:

Condition 1: It Must Be Your Primary Residence

The mortgage interest deduction only applies to your hoofdverblijf — your main place of residence. This deduction applies only to your primary residence, meaning the property where you actually live. Investment properties or rental homes are not eligible.

Condition 2: Mortgage Taken Out After 1 January 2013 — Annuity or Linear Only

If you took out your mortgage for the first time on or after January 1, 2013, you are entitled to deduct your mortgage interest payments from your taxable income for a maximum of 30 years. You must hold an annuity or linear mortgage, and the mortgage term must be no more than 30 years.

Interest-only (aflossingsvrij) mortgages taken out after 2013 do not qualify for the deduction.

Condition 3: Mortgage Taken Out Before 1 January 2013

If you took out your mortgage before 2013, older transitional rules (overgangsrecht) apply. You may still be eligible for the deduction under different conditions including on some interest-only mortgages but the deduction will still run for a maximum of 30 years from the original mortgage date.

Important: If you took out a mortgage in or before 2001, your 30-year deduction period will expire in 2031. After that date, you can no longer deduct mortgage interest, and your net monthly housing costs will increase.

Condition 4: The Mortgage Is for Buying, Improving or Maintaining Your Home

The loan must have been taken out specifically to purchase, renovate, or maintain your main residence. These costs are only deductible as long as they are related to a mortgage taken out to buy a property that you use as your main residence.

Understanding the Eigenwoningforfait (Notional Rental Value)

Before you can calculate your mortgage interest deduction benefit, you need to understand the eigenwoningforfait one of the most confusing aspects of Dutch housing taxation.

What Is the Eigenwoningforfait?

If you own a home, you must include an amount in your income tax return: the eigenwoningforfait. The Belastingdienst treats this as income you earn from your home. The logic is that by owning rather than renting, you are effectively “earning” the equivalent of rent and the Dutch tax system taxes a notional (fictional) version of that income.

Eigenwoningforfait Rates in 2026

The percentages according to the Belastingdienst in 2026 are as follows: for a WOZ value between €75,000 and €1,350,000, the percentage is 0.35%. For a WOZ value above €1,350,000, the amount is €4,725 plus 2.35% of the value above €1,350,000.

The higher rate above €1,350,000 is informally known as the villataks (villa tax).

How the Eigenwoningforfait Affects Your Deduction

The eigenwoningforfait is added to your taxable income, while your mortgage interest is subtracted. The net result your mortgage interest minus the eigenwoningforfait is what gives you the actual tax benefit.

In most cases where homeowners still have a meaningful mortgage, the mortgage interest deduction is larger than the eigenwoningforfait, resulting in a net tax saving. As your mortgage is paid off over time, the eigenwoningforfait begins to outweigh the deduction, reducing your overall benefit.

Worked Example: How Much Can You Save in 2026?

Let’s work through a realistic example using 2026 rates.

Your situation:

• Gross annual income: €75,000
• Mortgage: €300,000 at an interest rate of 4%
• Annual mortgage interest paid: €12,000
• WOZ value of home: €400,000
• Eigenwoningforfait: €400,000 × 0.35% = €1,400

Step 1: Calculate your net deductible amount Mortgage interest paid: €12,000 Minus eigenwoningforfait: €1,400 Net deduction: €10,600

Step 2: Calculate your tax saving Net deduction × 37.56% (2026 capped deduction rate) €10,600 × 37.56% = €3,981 tax saving per year

Step 3: Your monthly benefit €3,981 ÷ 12 = approximately €332 per month

This means your effective monthly mortgage cost is reduced by around €332 — simply by claiming the deduction you are legally entitled to.

Note: This is a simplified calculation. Your actual saving depends on your exact income, mortgage structure, and WOZ value. Use our Dutch Tax Calculator for a personalised estimate.

What Costs Can You Deduct in Addition to Mortgage Interest?

Mortgage interest is the main deductible item, but it is not the only one. In addition to the annual mortgage interest, you may also deduct certain costs incurred in the year of purchase once. These one-off deductible costs include:

Costs deductible in the year of purchase:

• Mortgage advisory and arrangement fees (advieskosten)
• Valuation/appraisal costs (taxatiekosten)
• Notary fees for the mortgage deed (notariskosten hypotheekakte)
• National Mortgage Guarantee costs (NHG — Nationale Hypotheek Garantie)
• Commitment fee for extending your mortgage offer

Ongoing deductible costs:

• Annual mortgage interest on your primary residence
• Ground lease payments (erfpacht) in some circumstances

Also deductible if relevant:

• Penalty interest, which you pay when refinancing your mortgage, is also deductible. This is particularly relevant for homeowners who break their fixed-rate mortgage early to get a better rate.

What you cannot deduct:

• Repayment of the mortgage principal (only the interest portion)
• Mortgage interest on a second home or investment property
• Home insurance premiums
• Maintenance and renovation costs (unless financed through a qualifying mortgage)

How to Claim the Mortgage Interest Deduction in 2026

There are two ways to receive your mortgage interest deduction in the Netherlands:

Option 1: Annual Tax Return (Belastingaangifte)

The amount you receive through the mortgage interest deduction is paid in one instalment on your account annually after you have filed your tax return.

The Belastingdienst pre-fills most of your mortgage data in the online return at Mijn Belastingdienst. You log in using your DigiD, verify the pre-filled figures, add any additional deductible costs, and submit. The refund is then processed after your return is assessed.

Filing deadline for 2025 income: 1 May 2026 (extensions available on request)

Option 2: Monthly Provisional Refund (Voorlopige Teruggaaf)

If you prefer not to wait until after filing your annual return, you can apply for a voorlopige teruggaaf (provisional tax refund) that spreads your benefit across 12 monthly payments.

With a provisional assessment, you get a monthly provisional refund of your mortgage interest, which is an advance on your mortgage interest deduction. The amount will appear in your account on the 15th of each month, described as IB/PVV.

You can apply for or amend the provisional refund at any time through Mijn Belastingdienst. If your income or mortgage changes, update it promptly otherwise you may need to repay amounts later.

The 30-Year Limit: When Does the Deduction Expire?

The mortgage interest deduction is a well-known but sometimes confusing scheme. It applies only to the mortgage on your primary residence and under certain conditions. The deduction is being phased out in steps since 2020.

The most important time limit to understand is the 30-year maximum. The mortgage interest deduction runs for a maximum of 30 years from the date your mortgage was taken out. After 30 years, you can no longer deduct any mortgage interest even if you still owe money on the loan.

What this means in practice:

• Mortgage taken out in 2001: deduction expires 2031
• Mortgage taken out in 2013: deduction expires 2043
• Mortgage taken out in 2020: deduction expires 2050

If you took out your mortgage in or before 2001 or inherited an older mortgage structure mark 2031 in your calendar. After that date, your net monthly housing costs will increase meaningfully.

The Wet Hillen: What Happens When Your Mortgage Is Almost Paid Off?

There is a specific rule that affects homeowners who have almost fully paid off their mortgage — called the Wet Hillen. This rule provides a partial deduction for homeowners whose eigenwoningforfait exceeds their mortgage interest deduction (i.e. when you owe very little mortgage interest).

However, the Tweede Kamer decided in the Belastingplan 2026 to accelerate the phase-out of the Wet Hillen. The tax benefit decreases from 2026 at a rate of 4.8% per year instead of the previous 3.33% per year. The full phase-out is now scheduled for 2041 instead of 2048.

This change particularly affects homeowners who have aggressively paid off their mortgage and now owe little or no interest. If you are in this situation, consult a Dutch tax advisor to review whether accelerating or slowing repayments makes financial sense.

Mortgage Interest Deduction for Expats in the Netherlands

If you are an expat living in the Netherlands with a Dutch mortgage, the hypotheekrenteaftrek applies to you in the same way as Dutch nationals — provided your mortgage and property meet the eligibility conditions.

Does the 30% Ruling Affect the Mortgage Interest Deduction?

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, there is an important interaction to understand: the partial non-resident status (which allowed 30% ruling holders to exclude foreign Box 3 assets) ended on 31 December 2025. From 2026 onwards, all Dutch residents including 30% ruling holders are fully resident for tax purposes and must declare worldwide assets. This does not remove the mortgage interest deduction, but it affects your overall tax picture.

Fiscal Partners and the Mortgage Deduction

If you and your partner are fiscal partners, you can divide the deduction between you in any ratio 100/0, 50/50, 30/70, etc. In the Belastingdienst filing program, you can adjust this division at the end of the filing process to find what works best for your combined situation.

This is particularly useful when one partner earns significantly more than the other and pays tax at a higher rate allocating more of the deduction to the higher earner maximises the total tax saving.

NHG Mortgage: Extra Benefits and Deductibility

The Nationale Hypotheek Garantie (NHG) is a government-backed mortgage guarantee available for home purchases up to a certain price limit. NHG mortgages offer:

• Lower mortgage interest rates (typically 0.3%–0.6% lower than standard mortgages)
• Protection if you cannot repay due to job loss, illness, or divorce
• The NHG guarantee fee (borgtochtprovisie) is fully deductible as a one-off cost in the year of purchase

The NHG purchase price limit for 2026 is €435,000 (or €461,000 for homes with energy-saving measures). This makes NHG relevant for a large portion of the Dutch housing market.Official Source: Full NHG details at nhg.nl

Common Mistakes to Avoid

Mistake 1: Not applying for a monthly provisional refund Many homeowners wait until after filing their annual return to receive their deduction. Applying for a monthly provisional refund gives you the benefit every month, improving cash flow immediately.

Mistake 2: Forgetting to deduct one-off purchase costs Mortgage advisory fees, valuation costs, and NHG costs paid in the year of purchase are all deductible — but only in that one year. Many first-time buyers miss this entirely.

Mistake 3: Not updating the provisional refund when circumstances change If your income increases, your mortgage is refinanced, or your interest rate changes, your provisional refund figure may become inaccurate. Always update it promptly to avoid a large repayment when you file your annual return.

Mistake 4: Assuming the deduction applies to a second home The hypotheekrenteaftrek applies only to your primary residence. Interest on a second home, holiday property, or buy-to-let mortgage is not deductible in Box 1.

Mistake 5: Not claiming penalty interest when refinancing If you pay penalty interest (boeterente) to break out of a fixed-rate mortgage deal early, this is fully deductible in the year paid. Many homeowners who refinance for a better rate miss this deduction entirely.

Mistake 6: Ignoring the 30-year countdown If your mortgage was taken out in or before 2001, plan now for the deduction expiring in 2031. Your net monthly housing costs will increase meaningfully when the deduction ends.

Frequently Asked Questions (FAQ)

Q1: What is the mortgage interest deduction rate in the Netherlands in 2026?

In 2026, the maximum rate at which you can deduct mortgage interest is 37.56%. This cap applies regardless of your actual income tax bracket — even if you pay the top rate of 49.5%, your mortgage interest deduction is limited to 37.56%.

Q2: What is the eigenwoningforfait and how does it affect my deduction?

The eigenwoningforfait is a notional rental value that the Belastingdienst adds to your taxable income as a homeowner. In 2026, it is 0.35% of your WOZ value for most homes (those valued between €75,000 and €1,350,000). You subtract this from your mortgage interest to calculate your net deductible amount. For most homeowners with an active mortgage, the interest deduction is larger than the eigenwoningforfait — resulting in a net tax saving.

Q3: Can I claim the Dutch mortgage interest deduction as an expat?

Yes. If you are a tax resident in the Netherlands and your mortgage meets the eligibility conditions — primary residence, annuity or linear repayment, maximum 30-year term — you can claim the hypotheekrenteaftrek in the same way as a Dutch national.

Q4: How do I claim the mortgage interest deduction in the Netherlands?

You can claim it in two ways. Either through your annual belastingaangifte (tax return) filed via Mijn Belastingdienst after the tax year ends, or monthly through a voorlopige teruggaaf (provisional tax refund) which spreads the benefit across 12 monthly payments throughout the year.

Q5: Is mortgage interest deductible on a second home in the Netherlands?

No. The hypotheekrenteaftrek applies only to your primary residence (hoofdverblijf). Interest on a second home, holiday property, or rental property is not deductible in Box 1.

Q6: What mortgage types qualify for the interest deduction in 2026?

For mortgages taken out on or after 1 January 2013, only annuity (annuïteitenhypotheek) and linear (lineaire hypotheek) mortgages qualify. Interest-only (aflossingsvrij) mortgages taken out after 2013 do not qualify. Older mortgages from before 2013 may still qualify under transitional rules.

Q7: How long can I claim the mortgage interest deduction in the Netherlands?

The maximum duration is 30 years from the date your mortgage was taken out. For mortgages taken out in 2001 or earlier, the 30-year clock started on 1 January 2001, meaning the deduction expires in 2031. After this date, you can no longer claim any interest deduction on that mortgage.

Q8: Can penalty interest (boeterente) be deducted from my taxes?

Yes. If you pay penalty interest when refinancing your mortgage or breaking a fixed-rate deal early, the full penalty interest amount is deductible from your taxable income in Box 1 in the year it was paid.

Q9: What is the NHG mortgage guarantee and how does it affect my deduction?

The Nationale Hypotheek Garantie (NHG) is a government mortgage guarantee for homes purchased up to €435,000 in 2026. The NHG guarantee fee is deductible as a one-off cost in the year of purchase. NHG mortgages also typically offer lower interest rates, which means a slightly lower interest deduction but lower gross mortgage costs overall.

Q10: Does the 30% ruling affect my eligibility for the mortgage interest deduction?

In most cases, no. If you are a tax resident in the Netherlands and hold a qualifying mortgage, you can claim the hypotheekrenteaftrek even if you also benefit from the 30% ruling. Note that from 2026, the partial non-resident status that some 30% ruling holders previously used has ended — but this does not remove your entitlement to the mortgage interest deduction.
