Becoming tax resident in Spain after buying property
Quick answer
You become tax resident in Spain when you meet a test in article 9 of the income tax law: more than 183 days in the calendar year, or the main base of your economic interests in Spain, or the family presumption. The change alters the taxes on your home and income.
Applies toBuyers who plan to move to Spain or to spend most of the year in their new home.

§ 1The moment
You do not choose to become tax resident; you become so by meeting a test. The Spanish tax agency describes them: more than 183 days in the calendar year, or the main base of activities or economic interests in Spain, or the presumption from a spouse and dependent minor children who habitually live there. The tests behind it are in how Spanish tax residence works.
§ 2Planning the year
Because residence is judged for the calendar year, the date you arrive affects the first year. A move in the middle of the year may or may not make you resident for that year, depending on your days and your interests. Count your days, and ask your adviser how the first year will be treated.
§ 3What changes
A resident is taxed in Spain on worldwide income, and files a return on that basis. The home itself is treated under the resident rules. A non-resident owner has a different set of obligations, set out in the non-resident rules that stop applying. The non-resident regime stops applying to you once you become resident, so you stop filing the non-resident returns for the home and start filing the resident return.
§ 4Assets abroad
A resident with assets abroad above set values must file an information return, as explained in more on Modelo 720. This is a new duty for many people who move. Prepare a list of your accounts, investments and property abroad before you arrive.
§ 5The other country
Moving to Spain does not automatically end tax residence elsewhere. The other country has its own rules. If both claim you, a tax treaty can decide, as more on treaty tiebreakers explains. Keep proof of your departure and of your new ties.
§ 6Immigration is separate
Becoming tax resident is not the same as obtaining a permit. EU citizens register their residence, non-EU nationals need a permit, and neither is the same as the tax question. Check each separately.
§ 7The first year
In the first year you may need to file a resident return, ask for tax certificates from the old country, register for local taxes, and update the bank, insurance and pension arrangements. Keep a folder with the dates of each step. Ask your adviser what must be done by which date, and put the deadlines in your calendar.
§ 8What to prepare
Before you move: list your income and assets, check the treaty with your home country, ask how your pension, rental and investment income will be taxed, plan the timing of the move, and arrange tax advice in both countries. After you move: register with the town hall, file your returns on time and keep your records.

FAQRelated questions
When does the change happen?
When you meet one of the tests in a calendar year. Residence is judged for the calendar year, so plan your move with that in mind and keep a record of your days and your ties.
What changes for my Spanish home?
Resident owners are taxed under the resident regime on their worldwide income, and the home’s tax treatment differs from that of non-residents. The costs section explains the non-resident regime and what stops applying when you become resident.
Should I tell my old country?
Often yes. You may need to end tax residence there, and a treaty may apply if both claim you. Ask a tax adviser in both countries before you move, and keep proof of your departure.
