Moving back to the UK: should you sell or let your Portuguese home?

Sell or let: how the two options compare

	Sell	Let (long-term lease)
Portuguese tax	50% of the gain at 12.5%–48%, once	25% of net rent every year, or 10% on housing leases up to €2,300 a month for rent received in 2026–2029
UK tax	None if sold before you become UK resident (unless temporary non-residence applies). If sold after, UK CGT at 18%/24%, less Portuguese tax and any private residence relief	UK income tax on the same rent at 20%/40%/45%, rising to 22%/42%/47% from 6 April 2027, less Portuguese tax
Main-home relief (Portugal)	Not available if you buy in the UK; it needs a new home in Portugal or the EU/EEA	Lost for good once the house stops being your tax address
Running costs	Stop at completion	IMI, insurance, upkeep, management, condominium fees for flats
Effort from the UK	One transaction, which can be signed by power of attorney	A tenant, repairs, two tax returns a year
Exposure	Converted to sterling at one exchange rate	Rent and value stay in euros; property prices rose 16.5% in the year to Q2 2026, but future moves can go either way
Getting out later	Not applicable	A sitting tenant can delay a sale and may have a right of first refusal

Worked example: selling a €450,000 Algarve villa now

Assumptions for illustration: bought in 2014 for €280,000, with €18,000 of purchase taxes and fees. Sold in 2026 for €450,000, paying 5% commission plus 23% VAT and €250 for the energy certificate. The owner has a €35,000 UK pension.

Step	Figure
Sale price	€450,000
Less €280,000 × 1.20 inflation coefficient (2025 table, provisional for 2026)	−€336,000
Less purchase taxes and fees	−€18,000
Less commission and VAT (€22,500 + €5,175)	−€27,675
Less energy certificate	−€250
Gain	€68,075
Taxable half	€34,037.50

When you sell	Portuguese tax	Net proceeds
While still resident in Portugal (half-gain added to €30,413 of taxable pension)	about €13,899	about €408,176
After leaving, as a non-resident (rate set by worldwide income: 32.37% average rate on €69,037.50)	about €11,019 (estimate)	about €411,056

Main-home relief would remove the Portuguese tax only if you reinvested in a home in Portugal or another EU/EEA state (article 10(5) of the IRS Code). A house in England does not count. Put your own figures into the selling calculator. The full non-resident method is explained in our capital gains tax guide.

Worked example: letting the same villa at €1,800 a month

Assumptions: one empty month a year, a 10% management fee plus VAT, IMI at 0.3% on an assumed taxable value (valor patrimonial tributário, VPT) of €180,000, and €700 insurance. Upkeep of pool, garden and repairs is put at €2,500. No mortgage.

Line	€ a year
Rent received (11 × €1,800)	19,800
Management (10% + VAT)	−2,435
IMI	−540
Insurance	−700
Upkeep	−2,500
Net rent before tax	13,625 (3.0% of value)

Your UK tax band	Portugal at 25%	UK top-up	Total tax	After tax	Yield on €450,000
Basic rate (22% from April 2027)	3,406	0	3,406	10,219	2.3%
Higher rate (42% from April 2027)	3,406	2,316	5,722	7,902	1.8%

Your UK tax band	Portugal at 10%	UK top-up	Total tax	After tax	Yield
Basic rate (22%)	1,362	1,635	2,998	10,628	2.4%
Higher rate (42%)	1,362	4,360	5,722	7,902	1.8%

This is simplified. HMRC computes the rent in sterling under its own expense rules, and the credit for Portuguese tax cannot exceed the UK tax on the same income. The lesson: for a UK taxpayer, the total tax is roughly your UK rate, or 25% if that is higher, whichever Portuguese rate applies. The 10% rate mostly moves tax from Portugal to HMRC. It saves money only for basic-rate taxpayers, and only a little.

How is the rent taxed in Portugal?

Non-resident landlords pay a flat 25% on Portuguese rent after deductible costs, or can opt for the progressive rates. Deductible costs include IMI, condominium fees, insurance, maintenance and management (article 41 of the IRS Code). You declare the rent on the annual return (Modelo 3, annex F) between 1 April and 30 June.

Decree-Law 97/2026 added article 45-C to the Tax Benefits Statute (EBF). It sets a 10% rate for rent received until 31 December 2029 under leases used exclusively for housing, where the monthly rent does not exceed 2.5 times the 2026 minimum wage: €2,300. It applies from 1 January 2026. The article sets no residence condition, and it adjusts the autonomous rate that non-residents pay. On its wording, non-resident landlords qualify. The tax authority has not published guidance confirming this. Holiday lets do not qualify.

Does the UK tax the rent as well?

Yes. A UK resident is taxed on worldwide income, so Portuguese rent goes on your Self Assessment return as overseas property income. You claim foreign tax credit relief for the Portuguese tax, capped at the UK tax on that income. The UK rates for 2026/27 are 20%, 40% and 45%. Finance Act 2026 creates separate property income rates of 22%, 42% and 47% from 6 April 2027. These cover overseas as well as UK property income.

Should you sell before or after you leave Portugal?

On the Portuguese side, the difference is small for most returners. Residents add half the gain to their other income. Non-residents pay an average rate set by worldwide income, which in our example came out about €2,900 lower. Main-home relief is out of reach either way if you buy in the UK. Portugal treats you as non-resident from your last day in the country (article 16(4) of the IRS Code).

On the UK side, timing matters more.

• Sell before you become UK resident and the UK normally has no claim on the gain. The exception is temporary non-residence (next section).
• Sell after you return and the UK taxes the gain at 18% or 24% after the £3,000 annual exempt amount. The gain is worked out in sterling using exchange rates at purchase and sale, and you get credit for the Portuguese tax. Private residence relief may cover the years the villa was your only or main home, plus the final nine months of ownership. If you sell within nine months of moving out, UK tax may be small. If you let first, the letting years are not covered. Lettings relief now applies only where you shared the home with the tenant.

The year you arrive may be split under the statutory residence test, so that only the part after arrival is UK-resident. Check the exact rules in HMRC’s RDR3 guidance.

The full UK computation is in our guide for UK residents selling.

What if you were away for less than five years?

HMRC’s temporary non-residence rules can apply if:

• you had sole UK residence in at least four of the seven tax years before you left
• your period abroad was five years or less

Gains made while abroad on assets you already owned when you left are then taxed in the UK in the tax year you return. Assets bought after you left the UK are generally excluded. Portuguese tax paid can be credited. So a villa bought before you emigrated and sold during a short stay in Portugal can still come into UK tax. Private residence relief may reduce the charge. Check this with a UK adviser before you exchange.

Can you keep it as a holiday home?

Yes, but you will be a visitor. UK citizens without an EU residence permit can stay in the Schengen area for 90 days in any rolling 180-day period, counted across all Schengen countries. The EU Entry/Exit System began its phased roll-out in October 2025 and has been fully operational since 10 April 2026. It records your fingerprints, facial image and every entry and exit, so overstays are detected automatically. ETIAS, the travel authorisation UK visitors will also need, is not yet operating. Check the EU’s ETIAS site before booking.

Costs continue:

• IMI is 0.3% to 0.45% of the VPT, set by each municipality.
• AIMI applies only above €600,000 of total residential VPT per person, or €1.2 million for couples filing jointly.
• Condominium fees continue for flats.

Homes left empty for over a year can be classed as unoccupied (devoluto), and some municipalities charge higher IMI on them. Holiday homes used for short stays are an exception under Decree-Law 159/2006. Keeping utilities connected and in use helps show the home is not abandoned.

Managing a Portuguese home from the UK

• Tax address. Update your address to the UK on the Portal das Finanças. Because the UK is outside the EU/EEA, you must either appoint a fiscal representative or sign up to electronic notifications (article 19 of the General Tax Law).
• Power of attorney. A procuração (power of attorney) lets someone in Portugal sign the deed or a lease for you. If signed in the UK, it must be notarised and apostilled, or signed at a Portuguese consulate.
• Tenants. A housing lease must run for at least one year (Civil Code, as amended by Lei 13/2019). Unless automatic renewal is excluded, it can bind you for several years. A tenant of more than two years has a right of first refusal if you sell (Civil Code article 1091). If you may sell within three years, do not sign a lease that renews automatically.
• Two returns. Rent means a Portuguese return and a UK Self Assessment return every year.

When selling usually wins

• You are buying a home in the UK and need the capital.
• You are a higher-rate taxpayer: net yield falls below 2% in our example.
• You have lived in the villa until now. Selling within nine months of moving out keeps the best chance of full UK private residence relief.
• You would need a manager for everything, or the property needs work before it can be let.
• You would rather hold sterling than keep euro exposure.

When letting usually wins

• You are a basic-rate taxpayer, the rent is within €2,300 a month, and a 2–2.5% net return plus possible price growth suits you.
• You may return to Portugal, or a family member will live there later.
• You bought recently and costs of sale would wipe out much of the gain.
• You have a trusted person on the ground and a lease that does not renew automatically.

Key points

• A UK home does not qualify for Portuguese main-home relief, so UK returners usually pay Portuguese tax on the sale whenever they sell.
• Portuguese tax on selling as a resident or a non-resident is similar: about €13,900 against €11,000 in our €450,000 example.
• UK tax depends on timing: none before you become UK resident (unless you were away five years or less), 18%/24% after, less Portuguese tax and any private residence relief.
• Rent is taxed at 25% in Portugal, or 10% on housing leases up to €2,300 a month for 2026–2029, and again in the UK with credit. Total tax is roughly the higher of your UK rate and the Portuguese rate.
• Letting our example villa returns about 2.3% after tax for a basic-rate taxpayer and 1.8% for a higher-rate taxpayer.
• As a holiday home, you are limited to 90 days in 180, now tracked by the Entry/Exit System.
