Dutch tax season brings a real opportunity for homeowners: a handful of genuine deductions that can add up to a meaningful refund, if you know what to claim and file it correctly. Here’s what you can actually deduct in 2026, how much it’s worth, and how to avoid the filing mistakes that cost people money.
Short answer
Dutch homeowners can lower their taxable income mainly through mortgage interest deduction, plus a set of one-off costs from the year they bought the property. But the maximum rate you actually get back in 2026 is capped at 37.56%, even if your income sits in the top 49.50% tax bracket. You don’t have to wait for your annual tax return either. Provisional rebate pays the estimated refund out monthly instead. Couples who buy together can also choose how to split the deduction, which can change the total refund.
What can Dutch homeowners actually deduct from their taxable income?
The main deduction is mortgage interest: interest paid on a loan used to buy or improve your primary residence. To qualify, the loan needs to be repaid within a maximum of 30 years, on either an annuity or a linear repayment scheme.
On top of that, a set of one-off costs from your purchase year are also deductible, more on those below, and homeowners can choose to receive the estimated refund monthly instead of waiting for their annual return.
How much of your mortgage interest do you actually get back in 2026?
Not your full tax rate. For 2026, mortgage interest can be deducted at a maximum rate of 37.56%. Even if your income falls in the top 49.50% income tax bracket, you’ll never get back more than 37.56% of the interest you paid. If your income is lower, you deduct at your own marginal rate, up to that same cap.
This matters for expectations: a high earner and a middle-income earner can end up with a similar deduction rate on their mortgage interest, even though their income tax rates differ substantially.
One-off purchase costs you can deduct in your first year
Several one-time costs from the year you bought your home are deductible, and claiming them typically produces the largest refund of your first year as an owner:
- Mortgage advisory and brokerage fees
- Notary fees for the mortgage deed
- Property valuation costs
- National Mortgage Guarantee (NHG) costs, if applicable
- Mortgage deed registration fees
One caveat: this only applies to the part of these costs you pay directly, not any portion you finance by increasing your mortgage. If you roll these costs into your loan, that extra amount is treated differently for tax purposes, so it’s worth checking with your advisor how you’re structuring it.
How to get your refund paid monthly instead of waiting a year
You don’t have to wait until you file your annual return, a provisional tax rebate pays your estimated refund out in monthly instalments instead. It’s especially useful in your first year, when the one-off purchase costs above make the refund larger than usual.
There’s a common trap in year two, though. The Belastingdienst doesn’t automatically update your provisional rebate to reflect a full year of interest instead of your first, partial year. You need to file that update yourself. Forget it, and your monthly payout can drop sharply without warning.
Buying with a partner? How to split the deduction
If you buy a home with a partner, you automatically become fiscal partners for tax purposes, and you can split the mortgage interest deduction between you in whichever proportion adds up to 100%. The split you choose can change your total refund, because each partner’s own income and tax position determines how much of the deduction actually benefits them.
There’s no single right split for every couple. It depends on both partners’ income and tax bracket, so it’s worth running the numbers with a tax advisor rather than defaulting to an even 50/50 share.
Getting your tax return right and where a tax advisor helps
The Belastingdienst pre-fills your return, but it’s worth checking the mortgage-related fields yourself before you submit, especially your one-off purchase costs and, in year two, your provisional rebate. Independent Expat Finance sees roughly half of its clients choose to work with a tax advisor for this step, since a good advisor can make sure nothing eligible gets missed. Our mortgage advisors can guide you through what’s available to claim, but we don’t file your tax return for you, that’s something you or your tax advisor handles directly.
Key takeaways
- Mortgage interest is deductible at a maximum rate of 37.56% in 2026, even for top-bracket earners.
- One-off purchase costs, advisory fees, notary, valuation, NHG, deed registration are deductible in your first year of ownership.
- A provisional rebate pays your estimated refund monthly instead of making you wait for your annual return.
- In year two, you must manually update your provisional rebate to reflect a full year of interest, or the payout drops.
- Buying with a partner lets you split the deduction, but the optimal split depends on both incomes, check with an advisor rather than assuming 50/50.
