How the Netherlands Taxes your Assets
As a Dutch resident, you are taxed on your worldwide income, which includes a property in Greece. Dutch income tax is split into three boxes, and investment assets such as real estate fall under Box 3. Box 3 works differently from income tax on a salary. Instead of taxing your actual income, it applies a deemed, or assumed, return to the value of your net assets above a tax-free threshold, and taxes that. For 2026, the figures are set as follows. The deemed return on "other assets," the category that includes property, is 6.00%, and the Box 3 tax rate on that return is 36%. The tax-free threshold is around €57,000 per person, roughly double for fiscal partners. These amounts are set each year, so it is worth checking the current figures at the time you file.
A System in Transition
Box 3 has been under legal challenge for years, because applying a fixed return rather than your real income can overtax people whose actual return is lower. Following rulings by the Dutch Supreme Court, there is now a counter-evidence route: if your actual return is lower than the deemed return, you can ask to be taxed on the lower, actual figure. The Netherlands also plans to move to a system based on real returns, where actual rental income is taxed, and expenses are deductible, with capital gains taxed on sale. This new system has been postponed more than once and is now expected around 2028. Until then, the deemed-return system above continues to apply.
How the Treaty Protects You
This is the part that matters most for a Greek holiday home. Under the double tax treaty between the Netherlands and Greece, income from real estate is taxed in the country where the property is located, so Greece. You still report the Greek property in your Dutch tax return, but you then claim double-tax relief for it. In practice, this means a Dutch resident with a second home in Greece is, in principle, not liable for Dutch income tax on that property. You declare it, and you receive relief.

Rental Income
If you do not rent out your home in Greece, this part does not apply to you, although note that the annual Greek property tax, ENFIA, is payable by all owners whether they let the property or not. If you do let it, you pay tax in Greece on the rental income. For individuals, the tax is progressive, charged on the gross rental income, and calculated per owner. The 2026 scale is:
Up to €12,000: 15%
€12,001 to €24,000: 25%
€24,001 to €36,000: 35%
€36,001 and above: 45%
Some deductions can apply, particularly for long-term lets, so the taxable amount is not always the full gross figure. A tax professional can confirm what applies in your case.
