Selling Property in Spain as a Non-Resident in 2026: Capital Gains Tax, Withholding, and Reinvestment Rules

💵 The Two-Tier Capital Gains Tax: 19% for EU/EEA, 24% for Non-EU

Capital gains on the sale of a Spanish property by a non-resident are taxed under Impuesto sobre la Renta de No Residentes (IRNR), not under the personal income tax that applies to fiscal residents. The taxable gain is the difference between the valor de transmisión (declared sale price, net of selling costs) and the valor de adquisición (original purchase price plus acquisition costs, plus capital improvements, indexed where applicable).

The rate depends on where the seller is tax resident at the time of sale, not on the buyer's nationality. Residents of EU member states, Iceland, Liechtenstein, Norway, the UK (post-Brexit transition preserved) and Switzerland are taxed at 19% on the gain. Residents of every other jurisdiction are taxed at 24%. The split was set by the 2021 IRPF reform and has not been touched in the 2024 and 2025 tax updates.

The 5-percentage-point gap matters on luxury stock. On a €400,000 taxable gain — a €900,000 sale four years after a €500,000 purchase — the EU seller pays €76,000 in IRNR capital gains tax. The non-EU seller on the same transaction pays €96,000. The €20,000 difference is not a planning wrinkle. It is the cost of holding the property through a UK LLP, a US LLC, or a BVI company instead of directly in the individual's name.

⚖️ The 3% Buyer Withholding: Modelo 211, Modelo 210, and How to Recover the Excess

The second tax that lands on a non-resident sale is not the IRNR itself but a flat prepayment the buyer is required to withhold at completion. Under article 25 of the IRNR regulations, any buyer acquiring urban property from a non-resident seller must withhold 3% of the declared purchase price and pay it to the Spanish tax authority (Modelo 211) within one month of the sale. The obligation sits on the buyer — if the buyer fails to withhold, the buyer becomes jointly liable for the IRNR that should have been collected.

The 3% is not a separate tax. It is a prepayment of the seller's IRNR capital gains tax, calculated on the gross sale price, not on the gain. On a €900,000 sale the buyer withholds €27,000 and remits it to Agencia Tributaria. The seller then files Modelo 210 within the next three months, declaring the actual gain, calculating the real IRNR due, and either paying the difference or claiming a refund of the excess.

The refund timing is the trap. Spanish tax law gives Agencia Tributaria six months to process a Modelo 210 refund from the date of filing. In practice refunds of under €30,000 clear in three to four months; refunds above €100,000 are routinely delayed six to nine months while the tax authority reviews the deduction schedule. Sellers who budget on the assumption that the 3% lands back in their account in time to close the next deal miscalculate by six months of liquidity.

🏛️ Plusvalía Municipal: The Second Property Tax Bill Most Owners Forget

Capital gains tax is the headline number. Plusvalía municipal — the local Impuesto sobre el Incremento del Valor de los Terrenos de Naturaleza Urbana (IIVTNU) — is the second property tax bill, levied by the town hall on the deemed increase in land value between acquisition and sale, not on the actual gain. The Constitutional Court ruled the old objective calculation method unconstitutional in 2021; town halls now apply either a real-estate-value-based formula or the lower of the objective or the actual gain on the land component.

The seller pays plusvalía, not the buyer. The amount depends on the municipality, the cadastral land value, the number of years held, and the coefficient table the town hall applies. On a €900,000 Marbella villa held for six years by a non-resident owner, plusvalía commonly lands between €4,000 and €12,000. The Marbella town hall publishes its coefficients, and the calculation is mechanical — but the seller has 30 working days from completion to pay plusvalía, with late-payment surcharges starting at 5% and rising to 20% plus interest after 12 months.

Plusvalía cannot be deducted from the IRNR capital gains tax. It is a separate tax, paid to the municipality, with a separate filing (the settlement is issued by the town hall based on the notarial deed of sale; the seller pays at the bank or via the town hall's online portal). Owners who budget only for capital gains tax and forget plusvalía see the net proceeds 1–2% below the projected figure on completion day.

📋 What You Can Actually Deduct Against the Gain

The IRNR taxable gain is not the gross sale price minus the original purchase price. Three categories of cost are deductible, and the difference between a seller who claims them and one who does not is typically 8–15% of the final tax bill.

Acquisition costs: ITP transfer tax paid on the original purchase (6–10% in Andalusia), notary fees, registry fees (Registro de la Propiedad), and the bank's appraisal fee from the original purchase. For new builds bought directly from a developer, IVA (10% VAT) and AJD (1–2% stamp duty) are deductible in addition. Legal fees on the original acquisition are deductible up to the limit applied by the tax authority in your home country DTT.

Capital improvements: documented renovation or extension costs, supported by invoices and bank transfers (cash payments are not deductible). The improvement must add value to the property — a kitchen renovation qualifies, general maintenance does not. Keep the original invoices plus bank statements showing the transfer; Agencia Tributaria routinely rejects unsubstantiated improvement claims.

Selling costs: real estate agent fees (typically 5% + VAT on Costa del Sol), legal fees for the sale, the energy performance certificate (€150–€300), the notary fee for the sale deed, and the registry inscription fee. The plusvalía municipal cannot be deducted from IRNR — it is a separate tax — but selling costs can be netted against the gross sale price to reduce the valor de transmisión.

⏱️ The 90-Day Filing Window: Modelo 210, Penalties, and What Happens If You Miss It

The IRNR capital gains declaration is filed on Modelo 210, due within three months and three working days of the date of sale. The deadline runs from the date in the notarial deed of sale (escritura de compraventa), not from the date the buyer paid or the date funds cleared into the seller's account. Missing the deadline triggers a requerimiento from Agencia Tributaria and a late-filing surcharge calculated on the tax due: 5% if paid within three months of the deadline, 10% if between three and six months, 15% if between six and twelve months, and 20% plus interest thereafter.

The 3% withholding the buyer already paid (Modelo 211) does not extend the Modelo 210 deadline. The two filings are independent — the buyer files Modelo 211 within one month of sale, the seller files Modelo 210 within three months and three working days. The seller nets the two on the Modelo 210, paying the difference or claiming the refund, but both deadlines run on their own clock.

Modelo 210 is filed electronically through the Agencia Tributaria portal, with a Spanish digital certificate (certificado digital), Cl@ve PIN, or the EU-wide eIDAS authentication. A non-resident seller without a Spanish digital certificate typically engages the Spanish tax representative to file on their behalf under a power of attorney (poder notarial) granted before the sale completes. The representative obtains an NIE-based certificate linked to the seller and files electronically.

🏠 Reinvestment: When the Primary-Residence Rules Apply

Spain's main capital gains exemption — the primary-residence reinvestment relief that lets a fiscal resident sell their home and defer the gain by buying a new primary residence within two years — does not apply to non-resident sellers. IRNR sellers have no equivalent relief available under domestic law. The gain is fully taxable at the 19% or 24% rate, with no rollover.

What does work for non-residents is the over-65 capital gains exemption under certain regional regimes. As of 2026, Andalusia does not offer a regional capital gains exemption for property sales. The historical €12 million exemption for the sale of a primary residence owned by an over-65 seller is a fiscal-resident benefit under IRPF, not IRNR — non-residents do not qualify. Sellers over 65 from outside Spain pay the full 24% IRNR on the gain, with no age-based reduction.

Two structural reliefs do apply across the board. Indexation of the acquisition value — since the 2015 IRPF reform, the acquisition value can be uplifted by inflation coefficients published annually by the Spanish tax authority in the Ley de Presupuestos Generales del Estado. For a property bought in 2015 and sold in 2026, the indexed acquisition value reduces the gain by 22–28% depending on the year-by-year coefficient. Inflation erosion of long-held property — a property bought in 2005 for €300,000 and sold in 2026 for €600,000 looks like a €300,000 gain. Adjusted for inflation, the real economic gain is roughly €80,000. The IRNR still taxes the nominal €300,000, not the real €80,000 — this is the single most expensive gap for long-hold sellers, and it is not closing.

📊 Worked Example: Selling a €900,000 Marbella Villa in 2026

Take a UK-resident owner selling a Marbella villa bought in 2019 for €600,000, holding period seven years. The 2026 sale closes at €900,000. Acquisition costs: €42,000 ITP, €1,800 notary, €450 registry, €400 appraisal — €44,650 in total. Capital improvements over the hold: €60,000 documented kitchen and terrace renovation, supported by invoices and bank transfers. Selling costs: €54,000 agent (5% + VAT) + €1,500 legal + €250 EPC + €900 sale notary + €400 registry inscription = €57,050.

Compare the same sale by a US-resident seller holding the property through a personal name. The IRNR rate is 24%, raising the capital gains tax to €11,750. Net to seller drops to ~€823,700. The same sale by a Gulf-resident seller holding through a BVI company adds 25% Spanish corporate tax on the gain before distribution, with 0% dividend WHT under the Spain-BVI non-DTT — the structure swallows the gain before it reaches the owner. Holding through a personal name remains the cheapest path for a non-EU owner, despite the 5pp higher IRNR rate.

📋 The Pre-Sale Checklist for Non-Resident Owners in 2026

The non-resident sale in 2026 is not a tax event to be surprised by. It is a procedure with three independent filings, three independent deadlines, and one predictable refund timeline. The sellers who keep the most money are the ones who engage a Spanish tax representative before listing, document every cost they incurred during the hold, and treat the 3% withholding as recoverable cash rather than lost revenue. The sellers who lose the most money are the ones who wait until completion to ask a Spanish lawyer what they owe.
