The short answer: you are a Spanish tax resident for a calendar year if you spend more than 183 days in Spain, if your main business or economic interests are in Spain, or, unless you prove otherwise, if your spouse and minor children live in Spain. Residents pay Spanish income tax on their worldwide income; non-residents only on income from Spain.
Tax residency is the single most important question for anyone moving to Spain, buying a holiday home or working remotely from the coast. It decides which country can tax your salary, pension and investments, which returns you file, and whether you can use special regimes like the Beckham Law. It is also a question of facts, not of paperwork.
The three tests
Spanish income tax law sets out three criteria. Meeting any one of them is enough.
1. More than 183 days in Spain
You count the days you are physically in Spain during the calendar year (1 January to 31 December). Sporadic absences, such as holidays abroad, count as days in Spain unless you can prove that you are a tax resident in another country, normally with a tax residence certificate from that country.
2. Your centre of economic interests
If the main core or base of your business activities or economic interests is in Spain, you are resident even with fewer than 183 days. Typical examples: most of your income comes from Spanish clients or a Spanish business, or most of your assets are in Spain.
3. The family presumption
If your spouse (not legally separated) and your dependent minor children habitually live in Spain, Spain presumes that you are resident too. You can rebut it by proving tax residency in another country.
What does not make you resident
- Your residence card or visa. A TIE, an EU registration certificate or a digital nomad visa are immigration documents. They don’t decide tax residency, although they are evidence of where you live.
- Registering on the padrón. Being on the town hall register is a useful indicator, but it is not the test.
- Owning a home in Spain. Plenty of non-residents own Spanish property. They file Modelo 210 instead.
Arriving or leaving mid-year
Spanish law has no split year: if you are resident, you are resident for the whole calendar year. If you move in July and spend fewer than 183 days in Spain that year, you are usually not resident for that year, unless one of the other tests applies. When two countries both consider you resident, the double tax treaty between them decides, looking in order at your permanent home, your centre of vital interests, where you habitually live and your nationality.
What changes when you are resident
| Obligation | What it means |
|---|---|
| Modelo 100 Annual income tax return | Filed from April to 30 June for the previous year. It covers your worldwide income: salary, self-employment, pensions, rents, interest, dividends and gains. Tax paid abroad is usually credited under the treaty. |
| Modelo 720 Assets abroad | An information return, due by 31 March, if your bank accounts, securities or real estate outside Spain exceed €50,000 in any of those categories. |
| Modelo 721 Crypto held abroad | An information return if you hold more than €50,000 in crypto-assets with providers outside Spain. |
| Wealth tax | Only for large net assets. The general allowance is €700,000, plus up to €300,000 for your main home, and the rules vary by region. |
If you also work as a freelancer, you register as autónomo and file quarterly VAT and income tax advances. Our guide to becoming autónomo in Spain explains the costs and deadlines for 2026.
The Beckham Law option
People who move to Spain for work and have not been Spanish tax residents in the previous five years can opt for the special regime known as the Beckham Law. Spanish employment income is then taxed at a flat 24% up to €600,000, and most income from abroad stays outside Spanish tax. You must apply within six months of registering with Spanish Social Security. Check whether you qualify.
If you are not resident
Non-residents only pay Spanish tax on Spanish income. If you own a property here, that means filing Modelo 210 every year, even if the property is empty. Keep a tax residence certificate from your home country: it is the simplest way to prove where you are resident if Spain ever asks.
