UK Resident Selling Property in Spain

For UK residents considering selling a property in Spain, it is essential to understand the tax implications and reporting requirements that come with such a transaction. Below, we explore all the key areas you need to know—from Spanish taxes and UK obligations to deadlines, deductions, and practical next steps.

Do I Need to Declare the Sale to HMRC?

If you are resident and domiciled in the UK you are taxed on your worldwide income and gains. A sale of a property in Spain must therefore be declared to HMRC on your self-assessment tax return. The UK and Spain have a Double Taxation Treaty, so you should not pay tax twice on the same gain. Any Spanish Capital Gains Tax (CGT) you have paid will normally be credited against the UK CGT due.

Because CGT is calculated differently in each country, you need to understand the rules in both Spain and the UK to work out whether you will owe additional UK tax.

Taxes Payable in Spain

When selling Spanish property, two main taxes may apply:

Plusvalía (Local Land Value Tax)

Plusvalía is a municipal tax charged by the local town council based on the increase in the rateable value of the land (the valor catastral del suelo) over the period of ownership.

• It is not linked to the market price of the property.
• The amount depends on how long you have owned the property and the council’s local rates.

Spanish Capital Gains Tax (CGT) for Non-Residents

Non-residents are taxed on the gain, calculated as the sale price minus the purchase price and allowable costs.

• Rates: 19% for EU/EEA residents; 24% for residents of other countries.
• Deductions: You may offset documented buying and selling costs (legal fees, notary, estate agent commissions) and qualifying improvement works.
• Main-home relief: Previously available to EU/EEA residents reinvesting in another main home, but UK residents are no longer eligible post-Brexit.

The 3% Withholding Tax (Retención)

On completion, the buyer must withhold 3% of the sale price and pay it directly to the Spanish tax authority as an advance payment of CGT.

• If the actual CGT due is less than the 3%, you can reclaim the difference by submitting a Modelo 210 tax return within four months of the sale.
• If your CGT liability is higher, you must pay the balance when filing.

Allowable Deductions and Proof of Costs

Both Spain and the UK allow certain costs to be deducted from the gain:

• Purchase and sale expenses such as legal fees, estate agent commissions, and notary charges.
• Documented capital improvements (extensions, major renovations).

• Inflation allowances where applicable.

Keep invoices, contracts, and proof of payment to support every deduction.

Currency Exchange and FX Gains

Spanish CGT is calculated in euros, but HMRC requires calculations in pounds sterling using the exchange rate on the purchase and sale dates.

• Currency movements can create a taxable UK gain even if there is little or no gain in euros.
• Keep official exchange rate records to ensure accurate UK reporting.

UK Capital Gains Tax

UK CGT is charged on the gain after deducting allowable costs and the annual CGT allowance.

• Rates for residential property: 18% for gains falling within any unused basic rate band and 24% for gains above it.
• Because UK rates can be higher than Spanish rates, you may need to pay a “top-up” to HMRC after claiming credit for the Spanish tax paid.
• Private Residence Relief may apply if the property was ever your main home, but strict conditions apply.

Double Taxation Treaty and Foreign Tax Credit

The UK–Spain treaty prevents double taxation. When completing your UK return, include the Spanish CGT paid and claim a foreign tax credit.

• HMRC will give credit up to the amount of UK tax due on the same gain.
• If UK tax is higher, you pay the difference.

Reporting Deadlines

Unlike UK property sales, there is no 60-day reporting requirement to HMRC for overseas property, but you must meet the self-assessment deadline.

Non-Resident Income Tax and Other Obligations

Ensure all annual non-resident income tax and local rates are up to date before completion. Outstanding taxes can delay the sale or be withheld from your proceeds.

Inheritance or Gifted Property

If the property was inherited or gifted, Spanish succession tax rules apply and you will need a probate valuation to calculate the gain. UK Inheritance Tax may also apply if you are UK domiciled.

Practical Selling Checklist

Before putting the property on the market, make sure you:

• Hold a valid NIE (Spanish tax ID).
• Obtain an energy performance certificate.
• Engage a Spanish lawyer to handle contracts, taxes, and the 3% retention refund.
• Keep records of purchase costs, improvements, and exchange rates.
• Budget for Plusvalía and both Spanish and UK CGT.

Worked Example

If you bought a Spanish property for €200,000 and sell for €300,000, with €10,000 of documented selling costs, your Spanish gain is €90,000.

• Spanish CGT at 19% = €17,100.
• Buyer withholds 3% of €300,000 = €9,000 at completion.
• File Modelo 210 to pay the balance (€8,100) or reclaim any excess.
• Convert to GBP for UK reporting. If UK CGT works out higher than €17,100 after relief, you pay the difference to HMRC.

Key Takeaways

Selling Spanish property as a UK resident involves tax in both countries, different calculation methods, and strict filing deadlines. Understanding Spanish CGT, the 3% withholding, UK top-up tax, and the Double Taxation Treaty will help you plan ahead, avoid penalties, and maximise any available deductions.
