Spain’s IRPF rules on worldwide income

Spain’s IRPF system treats anyone who spends more than 183 days in the country during a calendar year as a tax resident. That means filing the annual Declaración de la Renta and reporting worldwide income, including foreign pensions, dividends, rentals, investments, employment pay and capital gains.

Draft returns from the Agencia Tributaria can leave out overseas earnings, so residents have to add them manually. Double taxation treaties can soften overlap, but the reporting duty still applies.

Who gets caught by the 183-day rule

Digital nomads, expats and other long-stay visitors can cross into residency even with a visa that started as temporary. Partial days count and short absences still count toward the total unless a person can show tax residency somewhere else.

Non-residents face a narrower rule set. They are taxed only on Spanish-sourced income, such as local work or rental income and don’t have to declare worldwide earnings in Spain.

What nomads need to file

Residents file Modelo 100 online through the Agencia Tributaria portal, then add any foreign income missing from the draft return. The 2025 tax season filing window opened in late April 2026 and usually runs until June 30.

Foreign assets may also trigger Modelo 720 if they top €50,000 ($53,900). Penalties for omissions can be steep, so nomads who stay long enough to become residents should check income, assets and treaty relief before filing.
