Residencia fiscal (tax residency in Spain)

You are a tax resident in Spain if you spend more than 183 days here in a calendar year or if your center of economic interests is in Spain; in addition, you are presumed resident, unless you prove otherwise, when your spouse (not legally separated) and minor children live in Spain. The consequence is worldwide taxation: your Spanish income tax return covers all your income, wherever it is earned.

Sporadic absences count as days in Spain unless you can prove tax residency in another country, and the status applies to the whole year: Spain has no split-year residency. If two countries consider you resident at the same time, the tie is broken by the applicable double taxation treaty. The three tests in the law, with their articles, are set out in the guide are you a Spanish tax resident?.

In practice, the question comes up in the year you arrive or leave. If you arrive mid-year and exceed the days set by the law, you are resident for the whole year and your Spanish return also includes what you earned before coming. If you leave, it is wise to get a residency certificate from your new country to prove it.

The typical mistake is counting only days and forgetting the center of economic interests: an autónomo whose business and clients are here can be resident even while travelling a lot. Another error is believing that being registered somewhere else is enough.

Residency decides whether you pay resident income tax or IRNR, and whether you must file the informative return on assets held abroad. It is proven with the tax residency certificate issued by the AEAT.
