Selling or Renting Your UK Home After Moving to Spain: Tax for Britons

Selling or renting your UK home after moving to Spain puts one property under two tax systems. HMRC keeps the right to tax UK land: a seller who is no longer UK resident must report the sale within 60 days of completion, even with no tax due, and rent paid to a landlord abroad runs through the Non-resident Landlord Scheme. Spain taxes its residents on worldwide income and gains, then credits part of the UK tax. Private Residence Relief, the £3,000 allowance and the 18 and 24 percent rates shape the UK bill. This article is for informational purposes only and is not legal or tax advice; verify current requirements with the relevant Spanish authority or a licensed professional.

Which country taxes the sale or the rent?

Often both, in turn. Moving to Spain does not take a UK house out of UK tax. HMRC’s page on selling assets while living abroad says a non-resident pays Capital Gains Tax only in three cases, and the first is a gain on property or land in the UK. The other two are assets used in a UK branch of a foreign business and a return to the UK within 5 years of leaving. HMRC also states that double taxation agreements do not apply to tax on gains from selling UK residential property, so the UK collects its share whatever the treaty says.

Spain then looks at the same gain or rent from the other side. Under article 2 of Ley 35/2006, the law on personal income tax (IRPF, impuesto sobre la renta de las personas físicas), a Spanish tax resident is taxed on all income and gains wherever they arise and whoever pays them. Article 9 of the same law makes you resident if you spend more than 183 days in Spain in a calendar year, or if the main base of your economic activities or interests is in Spain; it presumes residence when your spouse, not legally separated, and your dependent minor children live in Spain.

The relief comes in Spain, not in the UK. Article 80 lets a Spanish resident deduct foreign tax on foreign income or gains, limited to the lower of two amounts: the tax actually paid abroad, or the Spanish average effective rate applied to the part of the taxable base taxed abroad. The Agencia Tributaria’s 2025 manual applies the average rate of the savings base to income in the savings base, and the general base rate to general income. For income covered by the treaty, HMRC’s taxed twice page puts the outcome plainly: where the two rates differ, you pay the higher one; it adds that the treaties do not apply to gains on UK residential property.

Three gaps matter. The pages read for this article do not include the UK and Spain treaty itself, do not set out how Spain computes the gain on a UK house, and do not say whether a Spanish exemption for selling a main home could apply. None of these pages distinguishes Britons covered by the Withdrawal Agreement, resident in Spain before 2021, from people moving now: the rules below apply to both as written. Whether HMRC sees you as resident in the year of the sale turns on the Statutory Residence Test and the split year, set out in our guide to leaving UK tax residence.

Selling or letting: the two paths side by side

Selling: the 60-day report and what home relief still covers

The report comes first

HMRC’s guidance for non-residents is strict on reporting. You must report a disposal of UK property or land even if no tax is due, even if you made a loss and even if you already file Self Assessment. Tax on UK residential property is reported and paid within 60 days of completion for completions on or after October 27, 2021, through an online Capital Gains Tax on UK property account; late reports and payments can bring interest and a penalty. The Private Residence Relief helpsheet HS283, updated April 6, 2026, repeats the 60 days for any non-resident disposal of UK residential or commercial property. On HMRC’s general page, a non-resident reports nothing else that has grown in value: only UK property and land.

The guidance adds that temporary non-residents who sell in a year spent abroad, or in the overseas part of a split year, face different rules. If a return to the UK is possible, read that section before you sell.

Rates and allowance

The rates page gives 18 percent on gains that fall within the basic rate band, £37,700 for 2026 to 2027, once added to your taxable income, and 24 percent on gains above it, from April 6, 2026. The page states these rates for gains in general, not by type of property. Before the rates, an individual can use the Annual Exempt Amount of £3,000, and HMRC’s non-resident guidance says it can be used only once in a tax year, even a split year.

Private Residence Relief

You pay no Capital Gains Tax on your home if it was your only home and your main home for the whole time you owned it, with no part let out (a lodger does not count). Once you move out, the “whole time” condition no longer holds, so the rules on absence decide the result:

• The last 9 months before the sale always qualify, wherever you lived, as long as the house was your only or main residence at some point.
• If it is your only home or the one you nominated, absences can qualify too: periods adding up to 3 years for any reason, up to 4 years for work elsewhere in the UK and any period while working outside the UK, provided you lived in the home before and afterwards unless work prevented it.
• If you own only one home, the longer 36-month final period applies only to a disabled owner, an owner in long-term residential care or a sale before April 6, 2014.

The same page warns that the rules are different when you are not UK resident for tax, and none of the HMRC pages read sets those rules out. The home sale guide points elsewhere for anyone who lives abroad, so have an adviser check the relief before you rely on it.

If you let the home before selling, HMRC gives full relief for the years you lived in it and the last 9 months of ownership. Letting Relief, at most £40,000, applies only when you lived there at the same time as your tenants, and covers nothing for the time the home stood empty.

Owners with a Spanish home as well should know the nomination rule: since April 6, 2015, an overseas property can be nominated as the main home only if you lived in it for at least 90 days in the tax year, and a nomination must be made within 2 years of each change in your combination of homes.

Stamp Duty Land Tax falls on the buyer in England and Northern Ireland; Scotland and Wales have their own taxes on buying. None of the pages read names a tax on the seller beyond Capital Gains Tax. HMRC keeps a separate page on selling property that is not your home.

Letting: the Non-resident Landlord Scheme

HMRC treats you as a non-resident landlord if you live abroad for 6 months or more a year, even if you are still UK resident for tax. By default, your letting agent deducts basic rate tax from the rent, after the expenses it paid, and gives you a certificate at the end of the tax year. With no agent, a tenant paying you more than £100 a week deducts it.

To receive rent gross, you apply on form NRL1i. If HMRC approves, it tells the agent or tenant to stop deducting, and you declare the rent through Self Assessment. HMRC will not approve you while your returns or payments are late.

Either way, you file a Self Assessment return unless HMRC tells you not to, which HMRC’s living abroad page says is usually needed when you rent out UK property, unless you have already claimed relief under a double taxation agreement. The return needs the residence section (SA109 on paper) and the property section (SA105). HMRC’s online services are not available to you: you send the return by post, use commercial software or use an accountant. The paper deadline is October 31.

A British citizen living in Spain keeps the Personal Allowance, as do EEA citizens and people who worked for the UK government in the tax year. You claim it after each tax year on form R43, and the standard amount is £12,570. If your rent stays below the allowance and tax was already deducted, the same form claims the refund. The rates page also lists a £1,000 allowance for property income, without saying whether it applies to non-residents.

Finance costs no longer reduce rent as an expense. HMRC’s landlord page, last updated in April 2017, shows 0 percent of finance costs deductible from 2020 to 2021, replaced by a tax reduction at the basic rate.

The Spanish side of a UK house you keep

A Spanish resident who lets a UK home declares that rent in Spain as well. The Agencia Tributaria treats rent from property you own, not used in a business, as rendimientos del capital inmobiliario, income from real estate. That page does not mention property abroad; the worldwide rule of article 2 is what brings UK rent in. For rent, HMRC sends you to the treaty and lists Spain among the countries with their own claim form, and Spain’s article 80 deduction then applies to the UK tax paid.

An empty UK house is less clear. Spain imputes a notional income on property that is neither let nor your main home, the imputación de rentas inmobiliarias, but neither AEAT page read says whether a home abroad is included. Ask an adviser before your first Spanish return.

A UK house also counts as a foreign asset. Modelo 720, the Spanish return on assets abroad, covers foreign real estate; after a first filing, the Agencia Tributaria asks for a new one when a block grows by more than 20,000 euros, and its own example names a sale (transmisión) as another reason to file. Article 54 bis of Real Decreto 1065/2007 makes the return compulsory for a property you stopped owning by December 31. The thresholds and deadlines are in our Modelo 720 guide, and the Spanish residence rules in our tax residence certificate guide.

Before you list the house or sign a tenancy

Decide the year of the sale first. Check your UK residence position for that tax year and your Spanish residence for that calendar year, then estimate the UK gain with the £3,000 allowance, and have an adviser confirm how much home relief applies while you are not UK resident. If you sell, diary the 60 days from completion before the exchange; if you let, consider sending form NRL1i early, since tax is deducted until HMRC approves it. Plan how the proceeds or the rent will reach Spain with our pounds to euros guide.

HMRC’s guidance describes the 60-day report through an online Capital Gains Tax on UK property account, or a paper form, and the NRL1i application for receiving rent gross. Get a tax adviser who works on both the UK and Spanish sides for a sale after you become Spanish resident, a home let for years, a Spanish home you might nominate, a possible return to the UK or an empty house in your Spanish return.
