You’ve taken the step. You’ve bought a home in the Netherlands and it feels good. But then comes the question: what do you actually pay monthly, and what does the Tax Authority expect from you as an owner? For expats, this is especially relevant, because Dutch tax rules sometimes work out differently than you’re used to from your home country.
Don’t panic. We’ll explain it step by step.
What are your monthly housing costs as a homeowner
When you buy a home in the Netherlands, your monthly cost structure changes considerably. For expats buying a house there are not only mortgage payments, but also a series of fixed costs that you may not have known as a renter.
The largest monthly expense is your mortgage amount. This consists of two parts: repayment and interest. In addition, you pay a monthly amount for your building insurance. This covers damage to the property itself, from fire, storm or leaks. Are you a member of an Association of Owners, a VvE? Then you also pay a monthly contribution for the joint maintenance of the building.
An expat who bought an apartment in The Hague paid 180 euros per month in VvE costs and 35 euros for his building insurance in addition to his mortgage. These are fixed costs that he hadn’t budgeted for in advance. Good to know before you make an offer.
Owner-occupied property allowance: what is it and what do you pay
This is the tax concept that surprises many expats. The Dutch government assumes that as a homeowner you enjoy a kind of fictional benefit by living in your own home. You pay income tax on that fictional benefit. This is called the owner-occupied property allowance.
The owner-occupied property allowance is calculated as a percentage of the WOZ value of your home. The WOZ value is the official value that the municipality determines annually. In 2024, the standard percentage was 0.35 percent for homes up to a certain value. With a WOZ value of 400,000 euros, this means an owner-occupied property allowance of 1,400 euros per year. You add this amount to your taxable income.
Sounds disadvantageous? Not really. Because at the same time you can deduct the mortgage interest from your income. And that deduction is for most homeowners higher than the owner-occupied property allowance. On balance, owning a home still offers a tax advantage.
Mortgage interest deduction: how does it work for expats
The mortgage interest deduction is one of the best-known tax benefits in the Netherlands. You can deduct the interest you pay on your mortgage from your taxable income. This lowers your income tax, sometimes significantly.
But note: this benefit only applies if you are tax resident in the Netherlands. Are you resident in the Netherlands as an expat and do you pay income tax here? Then in principle you are eligible for the mortgage interest deduction. Do you only live in the Netherlands for part of the year or have you been classified as a foreign tax resident? Then different rules apply and the deduction is sometimes limited.
At SMASH Makelaars we work with many expats who ask this question. The situation is different for everyone. An American consultant who lived in The Hague for three years and was fully tax resident in the Netherlands could deduct the full mortgage interest. A colleague who was registered in Germany but worked in the Netherlands had a different tax situation. Always seek advice from a tax advisor who has experience with international situations.
Municipal taxes and levies you shouldn’t forget
In addition to income tax, you pay local taxes as a homeowner. These are levied by the municipality where your home is located. The most well-known is the real estate tax, the OZB. This is an annual levy imposed by the municipality based on the WOZ value of your home.
You also pay water board tax. The water board is responsible for water management in your region and charges owners of real estate for these costs. Do you have a garden? Then in some municipalities you also pay sewerage levy as an owner.
A Japanese engineer who bought a home in Rijswijk received his first municipal assessments in January. He hadn’t accounted for the OZB and water board tax. Together they cost him over 900 euros per year. Not an astronomical amount, but important to know when determining your total housing costs.
The 30 percent rule and its impact on your tax position
Many expats in the Netherlands benefit from the 30 percent rule. This tax benefit means that thirty percent of your salary can be paid out tax-free. It is intended as compensation for the extra costs involved in working in another country.
The scheme affects your tax position as a homeowner. Because part of your income is untaxed, the mortgage interest deduction works out differently. You deduct the interest from a lower taxable income, which reduces the tax benefit. This is an important detail that many expats overlook.
Moreover, the 30 percent rule has a term. After that period, the benefit expires and your net income changes. This has direct consequences for your monthly spending capacity and thus also for your mortgage payments. Plan this ahead. A good tax advisor will help you prepare for this, so you don’t face surprises.
What changes tax-wise when you leave the Netherlands
Suppose your contract ends and you move back to your home country. But you keep your home in the Netherlands. What are the tax consequences then? This is a question we hear more often than you might think at SMASH Makelaars.
If you leave the Netherlands but keep your home as a rental property, the home shifts tax-wise from box 1 to box 3. In box 1 the home fell under owner-occupied property. In box 3 it is considered as assets. You no longer pay the owner-occupied property allowance, but you do pay tax on the value of the home as an asset. The mortgage interest is in that case no longer deductible.
If you rent out the home temporarily while still living in the Netherlands, special rules also apply. The rental income is in certain cases taxable and the home can temporarily shift to box 3. Make sure you sort this out in advance. A mistake in your tax return can cost you later.
Frequently asked questions about housing costs and taxes as an expat owner of a Dutch house
Must I always pay owner-occupied property allowance as an expat?
Yes, if you own your own home in the Netherlands and that home falls under box 1, you pay owner-occupied property allowance. This applies to virtually all homeowners who live in the home themselves. The amount depends on the WOZ value of your home.
Can I deduct the mortgage interest if I use the 30 percent rule?
Yes, you can. But the tax benefit works out differently than for someone without the scheme. Because part of your income is untaxed, your taxable income is lower. The deduction reduces your tax, but less than for someone with fully taxable salary. Have a specialist calculate this for you.
What happens to my taxes if I rent out my home after leaving the Netherlands?
Then your home shifts from box 1 to box 3. You then pay tax on the value of the home as part of your assets. The mortgage interest is no longer deductible. Depending on the tax treaty between the Netherlands and your new country of residence, additional rules may apply.
As an expat and homeowner in the Netherlands, you have to deal with more tax rules than the average buyer. But with the right knowledge and the right people by your side, it’s manageable.
