What taxes do I have to pay as a resident?

Tax residents in Spain are generally taxed on worldwide income, filed annually. Exact obligations depend on your personal situation — this is worth confirming with a tax professional for your specific case.

Do I automatically become a Spanish tax resident after 183 days?

Spending more than 183 days in Spain during a calendar year is the primary test, but you can also be considered a tax resident under other tests (your centre of economic interests, or your immediate family living in Spain) even if you're under 183 days.

Overview

Whether you're a Spanish tax resident or not is the single biggest factor in your tax obligations — it determines whether Spain taxes your worldwide income or only income sourced in Spain. This guide explains how residency is determined; for the practical registration steps, see our guide on how to become a tax resident.

Requirements

Relevant to anyone living in Spain for a substantial part of the year, regardless of nationality or visa status

Step-by-step process

Count your days in Spain during the calendar year — spending more than 183 days in Spain during a calendar year is the primary test for tax residency, and sporadic absences generally still count towards that total unless you can prove tax residency elsewhere
Check the 'centre of economic interests' test — even under 183 days, you can be considered a tax resident if the main base of your economic activities or interests is in Spain
Check the family test — if your spouse and dependent minor children live in Spain, you may be presumed a tax resident unless you can prove otherwise, even if you personally spend less time in the country
If any of these apply, you're generally treated as a full-year Spanish tax resident, taxed on your worldwide income for that entire tax year — Spain doesn't offer partial-year residency splitting for most cases

Required documents

Travel records or other evidence of days spent in Spain, if residency status is disputed
NIE/NIF

Common mistakes

Assuming residency is a choice — it's determined by these objective tests, not by whether you've registered anywhere or applied for a specific status
Not realising that becoming a tax resident partway through the year generally makes you a full-year resident for tax purposes, not just from your arrival date

Practical tips

Keep records of your travel dates if you split time between Spain and another country — this evidence matters if your residency status is ever questioned
If you're unsure whether you cross the 183-day threshold, check both this test and the economic interests test, since either one alone can make you a tax resident
