UK resident selling property in Spain: full tax breakdown
Selling a Spanish property as a UK resident in 2026 means dealing with three separate tax obligations: Spanish IRNR (income tax for non-residents), Spanish plusvalía municipal, and UK Capital Gains Tax. They overlap, but each has its own form, deadline and rate.
1. Spanish IRNR — Modelo 210
This is the main capital gains tax in Spain. As a UK resident (non-EU after Brexit), you pay 24% on the gain. EU/EEA residents pay 19% — UK lost that rate on 1 January 2021.
The gain is calculated as: (sale price − sale costs) − (purchase price + documented improvements + acquisition costs). Purchase costs include the original ITP/AJD, notary fees, and registry fees on the original deed.
Modelo 210 is filed within 4 months from completion. You pay any balance due, or claim a refund if your IRNR is lower than the 3% already withheld.
2. The 3% retention — Modelo 211
At completion, the buyer withholds 3% of the sale price and pays it directly to the Spanish tax office on your behalf. This is filed via Modelo 211 within one month of completion.
It's an advance payment of your IRNR. If your final IRNR (24% on the gain) is higher, you pay the difference. If it's lower (or there's no gain), you reclaim the surplus.
Important: if the buyer fails to withhold and pay the 3%, the property remains liable as a tax guarantee. That's why every Spanish notary will refuse completion unless the 3% is properly settled.
3. Plusvalía municipal
This is a local tax on the increase in cadastral land value during your ownership. In Valencia city the rate is 29.7% applied to the cadastral land base. Owed by the seller — even if non-resident.
Payable within 30 working days of completion. The buyer is the substitute taxpayer when the seller is a non-resident, so practical management usually goes through the notary.
4. UK Capital Gains Tax — HMRC
As a UK resident you must also report the disposal to HMRC. Since 6 April 2020, foreign property disposals are reported on your self-assessment return, not under the 60-day rule (which only applies to UK residential property).
UK CGT rates for residential property in 2026: 18% within the basic rate band, 24% for higher and additional rate. Your annual exempt amount (2025/26: £3,000) reduces the taxable gain.
Critically, the UK-Spain Double Tax Treaty (Article 13 and 22) allows you to credit Spanish tax paid against your UK liability. You don't pay 24% twice — you pay the higher of the two regimes effectively.
What you actually need to do
- Get a NIE if you don't have one. Required for any Spanish tax filing. Apply at the Spanish consulate in London or Edinburgh.
- Sign a power of attorney if you can't fly over for completion. Signed at the Spanish consulate or before a UK notary with apostille.
- File Modelo 210 within 4 months of completion. Online via the Spanish tax office portal (sede.agenciatributaria.gob.es) with digital certificate or Cl@ve. Or via a Spanish tax adviser.
- Pay plusvalía municipal within 30 working days. Usually handled by the notary or your local representative.
- Report on UK self-assessment for the tax year of completion. Claim foreign tax credit relief for Spanish tax paid.
- Repatriate funds. Spanish bank transfer to your UK account is the usual route. Watch the FX spread; specialist FX brokers (Wise, Currencies Direct, OFX) typically save 1-3% vs high-street banks on six-figure transfers.
Common pitfalls UK sellers hit
- Lost original deed. You can request a simple copy from any Spanish notary; the price is around €30-€50.
- No improvement invoices. Without invoices, improvements don't reduce the gain. Search through old emails and bank statements before filing.
- Missing the 4-month Modelo 210 deadline. Late filing carries 1-15% surcharge plus interest. Avoidable.
- Forgetting UK self-assessment. The Spanish system is opaque to HMRC, but they have full information exchange under FATCA-style agreements. Do not assume HMRC won't see it.
- FX spread. Sending €200k via a high-street bank can cost £3,000-6,000 in spread. Use a regulated FX broker.
