Form 210: IRNR Filing for Non-Resident Property Owners and Investors in Spain

The Non-Resident Income Tax (IRNR), regulated by Royal Legislative Decree 5/2004 (LIRNR), taxes income obtained in Spanish territory by individuals and entities that are not Spanish tax residents. Form 210 is the self-assessment return for non-resident income without a permanent establishment in Spain. The most common Form 210 obligations for property owners are: annual returns for rental income (from 1 to 20 April of the following year, under Order HAC/623/2026), annual returns for imputed rental income on vacant properties (from 1 April to 31 December of the following year, starting with 2026), and capital gains returns within the three months that follow the first month after a property sale. EU/EEA residents pay 19% on net rental income (after deductible expenses); non-EU residents — including UK residents after Brexit — pay 24% on gross income without expense deductions. When a non-resident sells a Spanish property, the buyer is required to withhold 3% of the sale price and pay it to the AEAT via Form 211 (Art. 25.2 LIRNR); the seller then files a capital gains Form 210 within the three months that follow the first month after the sale and can recover any excess withholding.

We manage the complete Form 210 IRNR compliance cycle for non-resident property owners and investors in Spain, from the initial obligation mapping and treaty-rate analysis through every annual filing, property sale capital gains return, and 3% withholding recovery.

Which return applies to you (Form 720, 721, 210 or the income tax return) is set out in tax returns for investors and non-residents in Spain. If you invest from Spain, see also the investor income tax return.

Why Non-Resident Property Owners in Spain Face Complex IRNR Compliance Obligations

The IRNR compliance obligations for non-resident property owners in Spain are more extensive than most property owners realise when they purchase. There are three separate types of Form 210 obligation for a non-resident owning a Spanish property:

1. Annual rental income return — for rented properties, previously filed quarterly; since Order HAC/623/2026 (Official State Gazette, 23 June 2026), rental income is filed once a year, from 1 to 20 April of the following year, so 2026 rental income is filed from 1 to 20 April 2027 when grouped (filed separately, the annual rule starts with rent accrued in the fourth quarter of 2026). EU/EEA residents declare net income after expenses at 19%; non-EU residents declare gross income at 24%.

2. Annual imputed income return — for any property that is not a permanent residence and is not rented out, the owner must declare 1.1% (or 2%) of the cadastral value as imputed income each year. This catches many owners who assume that not receiving rent means no tax obligation.

3. Capital gains return within the three months that follow the first month after any sale — regardless of whether there is a gain, the seller must file Form 210 to either pay the IRNR or recover the excess 3% that the buyer has withheld.

Each type of return has a different deadline, a different computation method, and a different rate depending on the owner’s country of residence. Missing any of them generates sanctions that accumulate year by year.

Our Service for Managing Form 210 IRNR Obligations for Non-Residents

We begin by mapping all the non-resident owner’s Spanish properties — number of properties, use (rented, personal use, vacant), location, cadastral values, and rental income history. We then determine all applicable Form 210 obligations and their deadlines.

For rental properties, we collect the year’s income and expense data from the owner, prepare the return with the correct rate (19% net for EU/EEA, 24% gross for non-EU), and file electronically within the deadline. For owners with multiple properties across different use categories, we manage the full compliance calendar.

For property sales, we coordinate with the buyer’s representative on the Form 211 withholding, prepare the capital gains computation (sale price minus acquisition cost, including legally recognised improvement expenditure), file the Form 210 within the three months that follow the first month after the sale, and manage the refund claim if the 3% withholding exceeds the liability.

We obtain and renew fiscal residency certificates from the tax authority of the owner’s country of residence, ensuring that treaty-rate benefits are correctly applied where available.

Regulatory Framework: IRNR (RDLeg 5/2004), Form 210/211 Filing Rules and Treaty Rates

Real Decreto Legislativo 5/2004 (LIRNR) is the consolidated text of the Non-Resident Income Tax Act. Art. 13 LIRNR defines income obtained in Spanish territory. Art. 24 LIRNR establishes the taxable base and applicable rates. Art. 25.2 LIRNR establishes the 3% buyer withholding on property purchases from non-residents. The Form 210 and Form 211 procedural rules are established by Orden HAP/2194/2013 and subsequent amendments. Spain’s double taxation treaties — more than 90 in force — provide reduced rates on specific types of income (dividends 5–15%, interest 0–10%, royalties 0–10%) that override the domestic LIRNR rates where more favourable.

• Voluntary regularisation of historic imputed income non-compliance for post-Brexit British owners, with reduced penalties through conformity.
• Capital gains Form 210 returns with successful recovery of excess 3% buyer withholding for sellers where the actual IRNR liability was less than the amount withheld.
• Treaty-rate application that reduced effective IRNR rates on dividends and interest from the standard 24% to the treaty rate of 5–15%.
• Fiscal representation under Art. 10 LIRNR for non-EU residents with AEAT-facing obligations.
