Renting Out or Selling Your Spanish Property: What UK Owners Actually Pay
A UK resident renting out a Spanish home pays 24% tax on the full rent, no deductions — EU owners pay 19% on the net. Selling is gentler. Here's what the UK-Spain treaty actually credits back, and what it doesn't.
This article is general information, not tax advice. Spanish and UK tax rules depend on your personal situation. Speak to a tax adviser who works across both countries before you file anything.
Buying was the easy part. The moment you rent out your Costa Blanca home, or sell it, Spain and the UK both want a share of the same euro — and since Brexit, the maths for a British owner isn't the same as it is for a French or German one.
Renting it out: Spain taxes you on the full rent, not the profit
If you let your Spanish property, Spain taxes the rental income first, through the non-resident tax (IRNR, Modelo 210). The rate depends on where you're resident — and this is where Brexit actually bites:
- An owner resident in the EU, Norway or Iceland pays 19% on the net rent — mortgage interest, community fees, insurance, repairs and other running costs are deductible first.
- A UK resident pays 24% on the full rent received — no deductions at all. Not the agent's commission, not the insurance, not a single expense. It's the highest non-resident rate Spain charges, and it applies to the whole amount your tenant pays, before a single cost comes off.
You'll also declare that same rental income in the UK, as part of your worldwide income — but there, the normal rules apply and your real expenses are deductible. The UK-Spain double taxation treaty (Article 22) then lets you credit the Spanish tax against what you owe in the UK on that income. The catch: the credit is capped at whatever UK tax is actually due on that same rent. Because Spain taxes the full amount at 24% and the UK only taxes the smaller net profit, it's entirely possible for the Spanish bill to be bigger than the UK credit can absorb — and that excess doesn't come back. It's paid, and it stays paid.
Selling it: capital gains is the gentler side, for once
Sell the property and Spain charges 19% on the gain — flat, the same rate for a UK resident as for anyone else, EU or not. The buyer withholds 3% of the price at completion on account (Modelo 211); you settle the rest, or reclaim the difference, via your own Modelo 210.
Back in the UK, the same gain falls under UK capital gains tax on residential property: 18% if it sits within your basic-rate band, 24% above it (2026/27 rates). The treaty credit works the same way as with rental income — Spanish tax offset against UK tax on that gain, capped at what the UK actually charges. Because 19% in Spain sits close to the UK's own 18–24% band, most UK sellers end up with the two taxes roughly cancelling out, sometimes owing a small top-up to the UK, sometimes losing a sliver of Spanish tax the credit doesn't fully cover. Nothing like the shock on the rental side.

Why the rental side is worse for a UK owner than an EU one
Before Brexit, a British owner paid the same 19% net rate as anyone else in the EU. Since 1 January 2021, HMRC and the Agencia Tributaria both treat UK residents as any other non-EU/EEA country: 24% on the gross rent, zero deductions. An EU resident with the exact same property, the exact same rent and the exact same costs pays less tax in Spain, on a smaller base, with a clean credit against home-country tax. That gap is Brexit, not a Spanish policy choice aimed at anyone in particular — it's simply what "outside the EU" means under Spanish non-resident tax law.
- 24% — Spain's tax on a UK resident's gross rental income, no expenses deductible.
- 19% — Spain's flat capital gains tax on sale, same for UK and EU residents alike.
- 18–24% — UK capital gains tax on residential property, by income band (2026/27).
What to have in place before you rent or sell
- A certificate of UK tax residency, so both administrations apply the treaty rate instead of the default one.
- Every rental invoice and receipt kept anyway — Spain won't deduct them, but the UK side will need them to work out your real net profit.
- Modelo 210 filed on the correct schedule: quarterly if you rent, within the deadline after completion if you sell.
- Your UK self-assessment declaring the same income or gain, with the Spanish tax credit claimed explicitly — it isn't applied automatically.
None of this is a reason to avoid renting out or eventually selling your Costa Blanca property — it's a reason to know the real numbers before you commit to either, and to have someone checking both sides of the return, not just the Spanish one. If you'd rather have that handled than untangle it yourself, an independent lawyer working only for you is the same protection here as it was at purchase.

Frequently asked questions
Do I pay tax twice if I rent out my Spanish property?
Not in the sense of paying the same tax twice to two governments for no reason — the UK-Spain treaty gives you a credit in the UK for the Spanish tax already paid. But the credit is capped at the UK tax due on that same income, and because Spain taxes UK residents on the full rent (24%, no deductions) while the UK taxes only your net profit, part of the Spanish tax can end up genuinely unrecovered.
What tax rate applies to a UK owner's Spanish rental income?
24% on the gross rent received, with no expenses deductible — the standard non-resident rate for anyone outside the EU/EEA, which has applied to UK residents since Brexit (1 January 2021). EU, Norwegian and Icelandic residents pay 19% on the net rent instead, after deducting costs.
Do I pay capital gains tax in both Spain and the UK when I sell?
Spain charges 19% flat on the gain (the same rate for UK and EU residents), and the UK charges 18% or 24% capital gains tax depending on your income band. The treaty lets you credit the Spanish tax against the UK bill on the same gain, and because the two rates sit close together, most UK sellers see them largely offset rather than stack.
Is the 24% rental rate really because of Brexit?
Yes. Before 1 January 2021, UK residents were taxed as EU residents: 19% on net rental income, same as a French or German owner. Since Brexit, Spain treats the UK like any other non-EU/EEA country under its non-resident tax rules — 24% on gross income, no deductions. It is not a penalty aimed at British owners specifically; it is simply what falling outside the EU/EEA means under Spanish law.
Do I need to file tax returns in both countries?
Yes. In Spain, Modelo 210 — quarterly if you rent the property out, and again when you sell. In the UK, you declare the same rental income or capital gain on your self-assessment, claiming the Spanish tax as a credit under the treaty. Neither country applies the credit for you automatically.
