Most non-resident owners think IRNR is a single annual filing. It isn't. For a rented Marbella villa it is four quarterly filings per year, plus a separate annual imputed-income filing, plus a 3% retention obligation if the buyer ever sells, plus a Modelo 720 collision if foreign assets cross €50K. Skipping any of them produces a surcharge stack that quietly compounds for years until a re-sale forces reconciliation.
IRNR (Impuesto sobre la Renta de no Residentes) is governed by Real Decreto Legislativo 5/2004 — Texto Refundido de la Ley del IRNR. Non-residents pay Spanish income tax only on Spanish-source income, filed on Modelo 210. The base rate is 24% for non-EU residents and 19% for residents of the EU, EEA (Norway, Iceland, Liechtenstein) plus those with a tax-information-exchange treaty in force. EU/EEA residents may deduct expenses; non-EU residents historically could not, though post-2023 case law (Tribunal Supremo 1185/2023) is opening this for jurisdictions with full information-exchange agreements. On a €2M Marbella villa rented at €120K/year, an EU non-resident pays roughly €7,000-12,000/year in IRNR after deductions; a US/UK/non-EU resident pays roughly €28,000/year without deductions, falling to ~€15,000 if treaty-based deduction claims succeed.
Every non-resident owner falls into one of four IRNR situations, each with its own rate, base, and form.
Most non-resident owners are in two scenarios simultaneously — Scenario B for any month the property sits empty, plus Scenario A for any month it generates rental income. The same calendar year can require both quarterly Modelo 210 filings (rental quarters) and an annual Modelo 210 (imputed income on empty months).
Until the Tribunal Supremo ruling 1185/2023 (October 2023), the split was rigid: residents of EU/EEA countries deducted expenses (mortgage interest, IBI, community fees, basura, depreciation, insurance, professional management, repairs); residents of non-EU countries (US, UK post-Brexit, UAE, Singapore, etc.) deducted nothing and paid 24% on gross rental income.
The Supreme Court has now ruled that this discrimination violates EU free movement of capital principles where the non-EU jurisdiction has a comprehensive tax information exchange agreement with Spain. AEAT has not yet updated its administrative guidance to fully implement this, but in practice tax advisors are now filing deduction claims for US, UK, and Swiss residents on the basis of CJEU C-388/19 (2021) and TS 1185/2023, with a 50-70% acceptance rate as of Q1 2026.
If you're a non-EU resident filing Modelo 210, your two paths are:
1. Conservative path: pay 24% on gross rental, accept the inflated bill, file annually without complication. 2. Optimised path: pay 24% on gross at the quarterly filing, then file a rectificative claim ("solicitud de rectificación de autoliquidación") within the four-year statute, asserting deduction rights under TS 1185/2023. Expect 6-18 months for AEAT response and budget €800-1,500 in legal fees per claim.
