When Spain can claim you through your economic interests

Key rules

• Either test: Meeting either the 183-day test or the economic interests test makes you resident.
• Under 183 days: Fewer than 183 days in Spain does not protect you if your main base of activities or economic interests is here.
• No fixed percentage: No set share of income decides the test; it is judged on the facts of your case.

Yes, you can be resident with fewer than 183 days

The two tests are applied separately, so passing one does not cancel the other.

The economic interests test asks whether the main base or centre of your activities or economic interests is in Spain, directly or indirectly.

One exception: if a tax treaty between Spain and another country applies, its tie-breaker rules can give residence to the other country.

What points to Spain

Spain is likely your centre of interests when most of your income or assets are tied to the country. These are the things that count:

• Most of your income comes from Spanish employment, self-employment or a business.
• You own Spanish real estate.
• You hold shares in Spanish companies, including holdings that control them, whether held directly or indirectly.
• Your investments and bank assets are in Spain.
• Your professional activity is run from Spain, or you run or direct a Spanish company.
• Your main home and daily life are here, and you can prove where you live.

How Spain weighs it

The tax agency (AEAT) and the courts look mainly at your taxable income for the year, leaving out capital gains from selling shares and similar assets. They look at where most of your income arises and where your assets, investments, businesses and professional activity are located.

If you have income in several countries

This is the hard case. If your income and assets are spread across countries, no single item decides it. Look at where the largest share of your income arises and where your businesses and main assets sit. If Spain comes out on top, expect Spain to claim you.

Family can add to the picture

If your spouse (not legally separated) and your minor children live habitually in Spain, the law presumes you are resident unless you prove tax residence in another country, for example with a tax-residence certificate. The proof is set out in How a spouse and children in Spain affect your tax residency.

What to do

Before you decide you are a non-resident, list your income sources, your assets and where your work is managed from. If Spain is the largest on that list, get advice from a tax adviser before filing.
