Capital Gains Tax When Selling Your Spanish Property: The British Owner’s Complete Guide (2026)

Capital Gains Tax When Selling Your Spanish Property: The British Owner’s Complete Guide (2026)

The moment you agree a sale price with a buyer for your Spanish property, 3% of that figure disappears before you ever see it. The buyer’s notary withholds it and sends it straight to the Spanish tax authority (AEAT). If that comes as a surprise, you are not alone. It catches British sellers out every year.

That withholding is just the beginning. Selling property in Spain as a UK citizen means navigating two Spanish taxes (IRNR capital gains and plusvalía municipal), a UK reporting obligation, and a tight filing calendar. None of it is complicated once you know the rules, but the penalties for missing deadlines run to 15-20% surcharges, so it pays to understand the process before you sign.

This guide covers every step: what you owe in Spain, how to calculate the actual gain, how the withholding works, and what HMRC needs to know.


The Two Spanish Taxes on a Property Sale

1. IRNR Capital Gains Tax (the national tax)

Non-resident owners pay Spanish capital gains tax under the Impuesto sobre la Renta de No Residentes (IRNR). The rate is 19% of your net gain for all non-residents, including UK owners post-Brexit. The 24% rate that catches British landlords on rental income does not apply to capital gains. CGT is 19% regardless of EU status.

That is confirmed in Spain’s domestic IRNR law (Ley 35/2006, Art. 25.1.g) and remains unchanged for UK sellers after January 2021.

2. Plusvalía Municipal (the local tax)

This is a council tax on the increase in the cadastral land value during your ownership. It is paid to the local ayuntamiento (town hall), not the national AEAT. It exists separately from the capital gains tax above and it is non-negotiable.

Since the Spanish Constitutional Court struck down the old calculation method in late 2021 (STC 182/2021), councils must now offer you two calculation options and you pay whichever is lower:

  • Objective method: cadastral land value × years owned × the municipality’s annual coefficient (national maximums apply)
  • Real gain method: actual profit × approximate land proportion (typically 30-40% of the total gain) × the council’s tax rate (maximum 30%)

In practice, the objective method tends to be lower for properties held fewer than 15 years. For a property in Estepona held for five years with a cadastral value of €180,000, the plusvalía bill typically runs €5,000-8,000. Rates vary municipality by municipality. Your Spanish lawyer or gestor can calculate it precisely once you have an agreed sale price.


The 3% Withholding at Source

Under Article 25.2 of the IRNR law, when a non-resident sells Spanish property, the buyer is legally required to withhold 3% of the agreed sale price and pay it to the AEAT within 30 days of completion, via Form 211. The seller receives the net price only.

This 3% is a payment on account of the seller’s CGT liability, not the final tax. You then file your own IRNR return (also Form 210, or Form 212 if reclaiming an overpayment) within four months of the sale.

If your actual CGT is less than the 3% withheld, you claim the difference back from the AEAT. Refunds typically take 6-18 months to arrive, so factor that into your cash flow planning.

If your actual CGT is more than the 3% withheld (common on high-gain properties), you pay the balance when you file.


Calculating Your Net Gain

The taxable gain is: sale price minus acquisition cost minus allowable deductions.

Allowable deductions from the sale price

  • Agent commission (typically 3-5% of sale price)
  • Notary fees and land registry fees on the sale
  • Lawyer’s fees for the sale

Allowable additions to your acquisition cost

  • Original purchase price
  • Purchase taxes and fees (ITP at 7% for resale, or IVA + AJD at 11.2% for new build)
  • Notary, land registry, and legal fees paid at purchase
  • Structural improvements (new kitchen, extension, pool): receipts required; routine maintenance does not qualify

Note: Spain abolished inflation-adjustment coefficients for property gains in 2015. You cannot adjust your historic purchase price for inflation, even if you bought 20 years ago.

Worked example

Sale price €550,000
Agent (3%) -€16,500
Notary / legal on sale -€5,000
Net proceeds €528,500
Original purchase price (2019) €380,000
Purchase taxes + fees (ITP 7% + costs) €32,600
Structural improvements €15,000
Total acquisition cost €427,600
Taxable gain €100,900
Spanish CGT at 19% €19,171
3% withheld by buyer (on €550k) €16,500
Balance still owed to AEAT €2,671

In this example you would receive €533,500 at completion (€550,000 minus the €16,500 withholding), then pay an additional €2,671 when you file your return.


Plusvalía: the Amount to Budget

For the same example property (cadastral value €180,000, held five years in Estepona), the plusvalía calculation using the objective method would run approximately:

  • Cadastral land value: €108,000 (60% of total cadastral, typical split)
  • Coefficient for five-year ownership: 4.45% per annum (the 2026 national maximum for this bracket)
  • Taxable base: €108,000 x 0.0445 x 5 = €24,030
  • Plusvalía at 28% council rate: approximately €6,728

That is paid separately to Estepona’s ayuntamiento, deadline 30 days from completion. Your gestor handles the filing.

Total Spanish tax bill on this sale: approximately €19,171 (IRNR CGT) + €6,728 (plusvalía) = €25,899 on a €100,900 gain.


What HMRC Needs to Know

You must also report the gain to HMRC, even if you already paid Spanish tax on it.

60-day reporting rule: Since April 2020, UK residents must report UK CGT on overseas residential property disposals within 60 days of completion and make a payment on account. Missing this deadline triggers an automatic £100 penalty.

The rate: UK CGT on residential property is 18% (basic-rate taxpayers) or 24% (higher/additional-rate taxpayers) for the 2025-26 and 2026-27 tax years. The annual exempt amount is £3,000 (2026-27).

Double tax relief: You claim the Spanish CGT you paid (€19,171 in the example above) as a credit against your UK CGT bill. You do not pay the same gain twice. The credit is calculated in sterling at the exchange rate on the date of the Spanish payment. Any excess Spanish tax (where the Spanish bill exceeds your UK liability) is not refundable by HMRC. You simply pay zero UK CGT, but you cannot claim back the difference.

Example continued: On the €100,900 gain (approx. £86,239 at 1.17 EUR/GBP), a higher-rate taxpayer’s UK CGT is £86,239 x 24% = £20,697. After subtracting the Spanish CGT credit of £16,386 (€19,171 at 1.17), the UK balance is approximately £4,311. After using the £3,000 exempt amount: net UK CGT owed approximately £3,111.

Always verify these figures with a UK accountant and a Spanish gestor working in tandem. This is exactly the situation where a dual-jurisdiction adviser earns their fee.


The Filing Calendar

Step Who files Deadline
Form 211 (buyer withholds 3%) Buyer’s representative 30 days from completion
Plusvalía (to the ayuntamiento) Seller via gestor 30 days from completion
IRNR return / Form 210 or 212 Seller via gestor 4 months from completion (to claim refund) or standard quarterly deadline
UK 60-day CGT report You / UK accountant 60 days from completion
UK Self Assessment return You / UK accountant 31 January following the tax year

Missing the 30-day plusvalía deadline typically triggers a 5-10% surcharge. Missing the IRNR filing triggers a 15% late surcharge plus interest.


Three Planning Points Worth Knowing Early

1. Structural improvements need paperwork. Improvements that reduce your taxable gain must be evidenced with invoices from registered Spanish builders. Cash-in-hand jobs you cannot document are disallowed. If you’re planning work on a property you intend to sell within a few years, keep every receipt.

2. Certificates of Fiscalidad (NIE currency). Your NIE must be active at the time of sale. If you obtained an NIE years ago but never became tax-registered in Spain, your gestor may need to submit a Form 030 before completing the sale to establish your tax identity properly. See our step-by-step NIE guide for the process.

3. The 3% lands in the tax year it is withheld. If you complete in late December and do not file your IRNR return until the following spring, the refund (if any) crosses a UK tax year boundary. Your UK accountant needs to know the exact completion date to file the 60-day return correctly.


Frequently Asked Questions

Do UK citizens pay 24% or 19% CGT in Spain?
19%. The 24% rate applies to rental income for non-EU residents, not capital gains. CGT is 19% for all non-residents, EU or otherwise.

What if my property has gone down in value?
If you sell for less than your total allowable acquisition cost, you have a capital loss, not a gain. There is no Spanish CGT to pay and no AEAT filing required (though some gestorias still file a nil return for clarity). You can also report the loss to HMRC to offset against other UK capital gains.

Can I avoid the plusvalía if I made a loss?
Since the 2021 Constitutional Court ruling, yes. If you can demonstrate that your property’s land value has not increased (i.e., you are selling at or below purchase price), you can pay zero plusvalía under the real-gain method. You need to document this formally through your gestor.

Who pays the plusvalía, buyer or seller?
By default and by law it is the seller’s liability. However, it is sometimes negotiated into the sale contract. If a developer or motivated seller is offering to cover it, that is a genuine financial concession worth quantifying.

Do I need a NIE to sell property in Spain?
Yes. You need a valid NIE as the tax identifier for both the sale deed and the IRNR return. See our NIE guide if yours needs renewing.


Ready to Sell, or Just Planning Ahead?

Whether you’re selling now or want to understand the numbers before you buy, the best time to get a gestor involved is before you accept an offer, not after you sign the deed. A good bilingual gestor will calculate your estimated net proceeds, structure the filing calendar, and handle both the IRNR return and the plusvalía filing on your behalf. Their fee (typically €400-800 for a sale) is itself deductible against your gain.
