Where do you pay tax when you live in Spain?

Q: What are those 183 days about then?

For Spain they are the rule. Article 9 of the Spanish income tax law makes you a tax resident in two cases: You stay in Spain more than 183 days in the calendar year . Sporadic absences count as presence, unless you prove you're a tax resident elsewhere. The main centre of your economic activities or interests is in Spain. And Spain presumes you live there if your spouse and minor children live there. In the Dutch tax treaties a different 183-day rule appears, about income from employment . That rule decides which of the two countries may tax your salary if you live in one and work in the other. It divides taxing rights over a specific kind of income, but doesn't determine where you live. Mixing up those questions is precisely the mistake. First it's established where you live. Only then does the treaty come in to determine who may tax what.

Almost everyone thinks it's about 183 days. That's not right: the Dutch Belastingdienst looks at your actual circumstances, and you can be in Spain for well over half a year and still live in the Netherlands for tax purposes.

Written and checked by Auke on 26 September 2026, against the sources at the bottom. Is something no longer right? Report it below and I'll fix it.

Where you pay tax when you live in Spain doesn't depend only on the number of days you spend there. Ask ten people who want to move to Spain where they'll pay tax, and nine mention the 183 days. That's half the story:

Spain does treat you as a tax resident as soon as you're there more than 183 days per calendar year.
The Dutch Belastingdienst doesn't count in days. It judges "according to the circumstances" whether you still live in the Netherlands.

So you can spend well over half a year in Spain and still live in the Netherlands under Dutch law. And if both countries claim you, the tax treaty decides in a fixed order.

How does the Netherlands determine where you live?

The Dutch Belastingdienst determines your residence on the basis of article 4 of the General Tax Act (AWR). That provision does no arithmetic. It says that where someone lives "is judged according to the circumstances". That means: all the facts, in context, case by case. What's weighed then isn't one thing but a sum:

Where is your permanent home, and do you still have one in the Netherlands?
Where do your partner and children live, and where do the children go to school?
Where do you work, and for whom?
Where do you bank, insure and see a doctor?
Where is your social life: family, club, GP, dentist?

The question behind it: is there still a lasting bond of a personal nature with the Netherlands? If so, you live here. How many days you were elsewhere doesn't in itself change that.

It's not about where you are, but about where your life is. A flat in Spain and half a year of sun change nothing as long as your house, your family and your work are here.

What are those 183 days about then?

For Spain they are the rule. Article 9 of the Spanish income tax law makes you a tax resident in two cases:

You stay in Spain more than 183 days in the calendar year. Sporadic absences count as presence, unless you prove you're a tax resident elsewhere.
The main centre of your economic activities or interests is in Spain.

And Spain presumes you live there if your spouse and minor children live there.

In the Dutch tax treaties a different 183-day rule appears, about income from employment. That rule decides which of the two countries may tax your salary if you live in one and work in the other. It divides taxing rights over a specific kind of income, but doesn't determine where you live.

Mixing up those questions is precisely the mistake. First it's established where you live. Only then does the treaty come in to determine who may tax what.

Is deregistering from the municipality decisive?

No. Your deregistration is a fact that counts in the assessment, just like your rental contract in Spain and your empadronamiento there. But it's one fact among the others. Do you keep your Dutch home, does your family stay here, and do you come back every month? Then that weighs more heavily than a line in the population register.

What if both countries think you live there?

The Netherlands and Spain each apply their own criteria. For that there's article 4 of the tax treaty between the two countries, with rules that are gone through in a fixed order until one country of residence comes out.

Step	Criterion	Source
Netherlands	residence "according to the circumstances": lasting bond of a personal nature	AWR article 4
Spain	more than 183 days per calendar year, or economic centre in Spain	Ley 35/2006 article 9
Treaty, rule a	where you have a permanent home; in both countries: centre of vital interests	treaty article 4(3)
Treaty, rule b	where you habitually stay	idem
Treaty, rule c	the state of which you're a national	idem
Treaty, rule d	mutual agreement between the tax authorities	idem
Return for the year of emigration	M return, online or on paper; reply usually within 3 months	Belastingdienst

Which of those rules is decisive for you depends on your facts. That's where this becomes a matter for a specialist.

How do you file for the year in which you move?

If you emigrate halfway through the year, you live part of that year inside and part outside the Netherlands. For that there's a separate return, colloquially the M form. You file it online through Mijn Belastingdienst, or with the paper M return form. You usually get a reply within three months.

That return is often forgotten. Put it in your planning for the year after your departure.

What do you decide before departure?

A few things are expensive or impossible to repair afterwards:

Whether you keep your Dutch home or not, and what that means for your residence assessment
What happens to your pension, and whether a protective assessment is in the picture
Whether you keep working for a Dutch employer, and how that works with wage tax and social security
When exactly you move, because the date determines your return

Vertrekklaar doesn't give tax advice: the working-out is personal and belongs with a tax adviser who knows both countries. Have that conversation before you move, not after.

In Vertrekklaar this is phase 2 of 5 of the journey, step 2.4: the same steps, but for your situation — in your order, tickable, and with the deadlines watched. See the whole journey to Spain or go straight to step 2.4 in the open plan.
