The 183-day rule: are you a Spanish tax resident?

The headline rule

Spain generally considers you a tax resident if you spend more than 183 days in Spanish territory during a calendar year. Sporadic absences can still count towards that total in some circumstances.

It is not only about days

Tax residency can also be triggered by:

• Having your main center of economic interests in Spain
• Having your spouse and/or minor children habitually residing in Spain, which can create a presumption of residency even if your own day count is lower

Why this matters

Tax residents are generally taxed on worldwide income in Spain, not just Spanish-source income.

The practical trap

Many expats track days spent in Spain but forget to also document days spent elsewhere (flight tickets, boarding passes) — if questioned, the burden of proving your day count is on you.
