You move to the Netherlands for work, but keep your old apartment. Perhaps you rent it out, let a relative stay there or leave it available for visits. Your daily life has moved. The property has not. When your Dutch tax return arrives, it may be unclear where that home belongs.
As a Dutch tax adviser, I help people report foreign property in their Dutch returns. My approach brings several questions together: what you own, what it is worth, which debt belongs to it and how relief from double taxation applies. I also check whether benefits or earlier returns need attention.
Start with your Dutch tax position
If you are a Dutch tax resident under the ordinary rules, you generally report assets outside the Netherlands as well as those held here. A privately owned second home abroad will usually fall within box 3, the part of Dutch income tax that covers savings and investments.
Your nationality does not settle the question. Nor does the country where you keep the property documents. What matters is which tax rules apply to you and how you own and use the home.
The year you move needs particular care. There is a separate return for a year spent partly living outside the Netherlands. A former main home that is empty and being offered for sale may also qualify for different treatment, subject to conditions. It should not automatically be treated like a holiday home. If you are also starting work here, my guide to your first job and taxes explains some of the checks on your pay and return.
A time limit some expats need to know about
Some people using the 30% ruling can still choose partial foreign taxpayer status under transitional rules through the 2026 tax year. Broadly, these are qualifying existing users from before 2024. Eligibility and the date the ruling ends need checking.
That choice can change which assets must be reported in box 3. A foreign home may fall outside the Dutch box 3 return while this status applies. This is different from reporting the home and then claiming relief from double taxation.
The transitional option ends after 2026 under the current rules. Having the 30% ruling does not, by itself, mean your foreign assets stay outside Dutch tax. This is one reason an old return, or advice given to a colleague, may be a poor guide to your own position.
Reporting a home does not always mean paying Dutch tax on it
If the home belongs in your Dutch return, paying property taxes abroad is not a reason to leave it out. Reporting tells the Dutch tax authority what you own. The next question is how the tax calculation deals with it.
Tax treaties often allow the country where the property is located to tax it. The Netherlands then gives relief from double taxation where the relevant rules provide for that relief. The treaty or other arrangement must be checked for the particular country and situation.
I do not leave the property out of the Dutch tax return. I report the property and any related debt, then apply the appropriate relief.
That relief does not make every foreign tax bill deductible from your Dutch bill. It also does not remove the need to look at your other savings and investments. Those assets can still produce Dutch tax, even when relief applies to the foreign home.
Work out exactly what you own
Imagine you inherited one third of an apartment with two siblings. A parent still lives there and pays no rent. You may think of it as the family home rather than part of your wealth. For the return, the ownership documents still matter.
With ordinary shared ownership, your share of the value is the starting point. A formal right for someone else to live there can require a different assessment. The same is true when a company owns the property. Owning shares in a company is not the same as owning the building directly.
This shows why I ask about the ownership share, how the property was acquired and how it is used. A description such as “our house back home” leaves important questions unanswered.
Use a value that fits the Dutch return
The value used for local property taxes may be based on rules quite different from the Dutch ones. An old purchase price may also be out of date. Neither figure should be copied into the return without checking what it represents.
For a foreign second home used privately, the standard box 3 calculation generally asks for its market value in vacant possession on 1 January of the year before the tax year. In plain English, this means its estimated sale value if it could be sold empty and available to the buyer. For a 2025 return, that valuation date is 1 January 2024.
That date is separate from the question of what you owned on 1 January of the tax year. Letting the property, buying it during the year or reporting actual returns can require other figures. I check which dates and supporting documents fit the return being prepared.
Useful evidence may include a local valuation, comparable sales or an estate agent’s assessment. Keep the explanation as well as the number. If the documents use another currency, keep that information too so the euro amounts can be checked.
Include the mortgage in the review
A loan connected with a second home can generally be included as a box 3 debt. You will need records showing the balance and what the loan financed. If ownership is shared, the property and debt figures must reflect the relevant arrangements.
Interest on a second-home loan does not automatically receive the relief available for a qualifying main-home mortgage in box 1. However, interest on a box 3 debt may matter when actual returns are calculated. I review the loan alongside the property, rather than treating it as a separate afterthought.
There is a practical point here too. Owning a valuable home does not make its value available for rent, repairs or other bills in the Netherlands. Keep money for those needs when deciding whether to pay off a mortgage or invest.
No rent does not necessarily mean no return
The Dutch box 3 system compares a calculation using fixed rates with your actual return when you report it and it produces a lower result. The actual-return calculation looks at all your box 3 assets and debts together. It is not a separate choice for each property.
Rent and changes in the home’s value can matter, even if you have not sold it. From 2026, an amount for private use also counts towards actual return. Ordinary maintenance costs are not generally deductible in that calculation. These details make it useful to keep records throughout the year.
I can compare the calculations and process the relief from double taxation. Including rent or a rise in value does not, on its own, tell you the final Dutch tax bill. The applicable relief still needs to be worked out.
Check Dutch benefits as well
Dutch healthcare benefit, rent benefit and the child-related budget have asset limits. A foreign holiday home can count towards those limits. Relief from income tax does not automatically remove the property from the benefits assessment. Childcare benefit has no asset limit.
You could therefore receive tax relief for a home while its value affects a benefit. This can be surprising after an inheritance: your wealth may have increased without your monthly income changing. The relevant year, your household and any special tax status all need to be considered.
Checking possible effects on benefits is part of my work on foreign property. It helps connect the tax return with what you actually receive each month.
If the home was missing from an earlier return
Gather the earlier returns and the documents showing when you became an owner. Note changes in your share, the loan and how the home was used. Avoid assuming that adding one figure to this year’s return also corrects previous years.
I review which returns need or can still receive a correction, taking account of the status of the tax assessments. The property, related debt and relief need to be handled together. An earlier omission calls for a review of the facts before deciding how to put it right.
For a first conversation, you can start with the address, country, purchase or inheritance date, ownership share and available value and loan records. Add rental information if relevant. If some documents are missing, make a note of what you still need.
My page on declaring foreign property in a Dutch tax return explains the help I offer. The service covers the Dutch return, including the property, debt, tax relief, possible benefit effects and earlier returns. Any filing required in the country where the home is located needs its own check.
