Buying a holiday home in Spain or Portugal as a UK resident: 2026 guide

A 2026 guide for UK residents buying a holiday home in Spain or Portugal, covering NIE and NIF paperwork, purchase steps, taxes, non-resident rules, selling, and common pitfalls.

The short answer is: it's not hard to do legally, but it's bureaucratic enough to feel hard if you go in unprepared. UK citizens face no restrictions on owning property in Spain or Portugal. What trips people up is the paperwork chain, getting the right tax identity number, opening a local bank account, understanding what you owe when you own it, and knowing what happens when you sell. Residency is a separate issue entirely. You don't need to live in either country to buy there.

This guide breaks down the UK-to-deed process for both Spain and Portugal in 2026, including the taxes most buyers underestimate and the pitfalls that turn a straightforward purchase into a months-long headache.

The UK-to-Spain route: what you need before you sign

Before you can complete any property transaction in Spain, you need a Numero de Identificacion de Extranjero (NIE), a foreigner identification number used for all tax and legal purposes. You can apply for a Spain NIE number from the UK through the Spanish Consulate in London (or other UK cities), though waiting times vary and appointments can be slow to come by. Many buyers appoint a Spanish lawyer to obtain the NIE on their behalf via power of attorney, which is often faster in practice.

Once you have your NIE, the typical purchase flow looks like this:

1. Find a property and agree on a price
2. Pay a reservation fee (typically EUR3,000-EUR6,000) to take it off the market
3. Sign a private purchase contract (contrato de arras) and pay around 10% of the purchase price
4. Complete legal due diligence (title search, planning checks, outstanding charges)
5. Sign the title deed (escritura publica) before a notary
6. Register the property at the Land Registry (Registro de la Propiedad)

You'll also need a Spanish bank account before the deed stage, and your lawyer will require proof of funds and Anti-Money Laundering (AML) documentation.

One thing worth being clear on: since Brexit, UK citizens are treated as non-EU nationals for many Spanish administrative and tax purposes. This isn't just a technicality, it affects which taxes apply, how mortgage applications are assessed, and what paperwork you need. The days of seamless EU movement simplifying these transactions are over for UK buyers.

The entire process from offer to keys typically takes 2 to 4 months for a resale property, though off-plan or rural properties with complex title histories can take considerably longer. You can browse current houses for sale in Spain to get a feel for regions and price points before committing to the process.

The UK-to-Portugal route: what you need before you sign

Portugal's equivalent of the NIE is the NIF (Numero de Identificacao Fiscal), your Portuguese tax number. Getting a NIF as a non-resident typically requires appointing a local fiscal representative, though some tax offices (Financas) will process applications directly. The NIF is needed before you can sign anything, open a bank account, or pay taxes.

According to legal firm Harris Sliwoski (writing in May 2026), the purchase process for foreigners in Portugal typically involves:

• Obtaining a NIF and, in practice, opening a Portuguese bank account
• Signing a reservation agreement followed by the Contrato de Promessa de Compra e Venda (CPCV), the binding promissory contract where you typically pay 10-30% of the price
• Completing due diligence on the title, planning permissions, and property tax status
• Signing the final deed (Escritura Publica de Compra e Venda) before a notary
• Completing the land registry (Registo Predial) transfer

The CPCV is legally binding. If the buyer pulls out without legal grounds, they lose the deposit. If the seller backs out, they typically owe double the deposit back.

One important point many UK buyers get wrong in 2026: buying property in Portugal does not qualify you for a Golden Visa. Portugal eliminated the real estate route for new Golden Visa applications as part of a structural overhaul. If your plan was to combine a holiday home purchase with a residency pathway, you'll need to explore alternative visa categories, property ownership alone no longer opens that door.

You can search current apartments for sale in Portugal and country homes in Portugal across regions including the Algarve and central Portugal.

Spain vs Portugal: complexity comparison for UK buyers

Both countries are accessible to UK buyers, but the friction points differ. Here's a practical side-by-side:

Where Spain gets complicated for UK buyers: ITP (the transfer tax on resale properties) varies by autonomous community, it's 8% in Madrid, 10% in Andalusia and Catalonia, and different again in Valencia. There's no single national rate. Factor in the non-resident imputed income tax (IRNR) on property you don't rent out, more on that below, and the CGT withholding mechanics when you eventually sell.

Where Portugal gets complicated: the IMT structure is calculated on a sliding scale based on property value and type of use (primary residence vs secondary home vs investment), and the Alojamento Local (AL) short-term rental regime has been subject to ongoing restrictions in municipalities like Lisbon and Porto. If you plan to rent on Airbnb or similar platforms, check the current AL rules for your specific municipality before buying.

For mortgages in either country: non-resident buyers typically face higher deposit requirements (commonly 30-40% of the purchase price vs 20% for residents) and more stringent income documentation checks. Some lenders are also more cautious with UK applicants post-Brexit.

Costs to budget beyond the property price

A common mistake is budgeting only for the purchase price. In practice, buying costs in both countries run to roughly 10-14% on top for resale properties.

In Spain:

• ITP (transfer tax, resale): 6-10% depending on region
• IVA + AJD (new builds): 10% VAT plus 0.5-1.5% stamp duty
• Notary fees: typically EUR600-EUR1,500 depending on property value
• Land Registry fees: ~EUR400-EUR1,000
• Legal fees: typically 1% of purchase price (minimum EUR1,500-EUR2,000)
• NIE and admin costs: a few hundred euros

In Portugal:

• IMT (property transfer tax): 0-8% on a sliding scale
• Stamp duty (Imposto do Selo): 0.8% of the purchase price
• Notary and registration fees: ~EUR1,000-EUR2,000
• Legal fees: typically 1-1.5% of purchase price
• NIF and fiscal representation: a few hundred euros

Budget an additional contingency of 2-3% for cross-border delays, document translation, re-submissions, and unexpected charges from the municipality or registry. These are genuinely common in international transactions and shouldn't catch you off guard.

Taxes when you own it: holiday use vs rental

Spain

If you own a Spanish property as a non-resident and don't rent it out at all, you still owe tax. Spain charges non-residents an IRNR imputed income tax, essentially a notional income on the property's rateable value (valor catastral). The rate is 24% on 1.1% or 2% of the valor catastral (the lower percentage applies to recently updated values). It's filed annually via Modelo 210.

If you do rent it out, rental income is taxed at a flat 24% for non-EU/EEA residents (which UK citizens now are). You can't offset expenses the way EU residents sometimes can.

In addition, the IBI (Impuesto sobre Bienes Inmuebles) is a local council tax paid every year, typically a few hundred euros depending on location and property type.

Portugal

Portugal's annual property tax is the IMI (Imposto Municipal sobre Imoveis), levied by the municipality. Rates typically range from 0.3% to 0.45% for urban properties (the exact rate depends on the local authority). Properties valued above EUR600,000 may also attract an AIMI surcharge, this applies on the aggregate taxable value above that threshold.

If you rent short-term through Alojamento Local, income is taxed at 28% for non-residents (with no deduction of expenses under the simplified regime). Long-term residential rentals have different treatment. The AL licensing regime itself has become more restrictive in urban centers, so verify current rules with a local lawyer before assuming short-term rental income is freely available.

Taxes when you sell: exit planning matters

This is where many UK buyers are caught unprepared, particularly in Spain.

Spain

When a non-resident sells Spanish property, the buyer is legally required to withhold 3% of the sale price and pay it directly to the Spanish Tax Agency (Agencia Tributaria) as an advance payment, this is the retencion del 3% and applies regardless of whether you've made a profit. The non-resident seller then files a Modelo 210 to reconcile: if the actual CGT owed (at the flat 19% rate on net gain) is less than the 3% withheld, you can claim a refund. If it's more, you pay the difference.

In practice, on a property that hasn't gained much in value, the 3% withheld can exceed the actual 19% CGT liability, meaning you'll be owed money back by the Spanish tax authority. That reconciliation filing takes time, and you'll need all your original purchase documentation to establish the cost basis.

There's also the plusvalia municipal (a separate municipal capital gains tax on the increase in land value), which is the seller's liability regardless of residency status.

Portugal

For non-residents selling Portuguese property, only 50% of the capital gain is included for income tax purposes (per PwC Tax Summaries, January 2026). That included gain is then taxed at a flat 28% rate. So on a EUR100,000 gain, EUR50,000 is included and taxed at 28%, an effective rate of 14% on the total gain, before any deductions.

Unlike Spain, there's no mandatory buyer withholding mechanism for the seller's CGT, but you still need to file a Portuguese tax return for the year of sale. Documentation of acquisition costs, improvement costs, and agency fees is essential to reduce the taxable gain.

For both countries, keep every invoice, notary deed, and bank transfer record from the original purchase. You'll need them when you sell.

Common pitfalls that make it feel 'hard'

Not appointing an independent lawyer. Using the seller's lawyer or the agent's recommended solicitor is one of the most common mistakes. Your lawyer's job is to protect your interests, not the deal. Always appoint someone who acts only for you.

Under-declaring the purchase price. Some buyers are encouraged to declare a lower value than actually paid. This is illegal, and it creates a worse CGT position when you sell (because your recorded cost basis is lower). It also exposes you to penalties.

Assuming the Golden Visa comes with the Portugal purchase. As confirmed by multiple legal firms in 2026, property purchases no longer qualify for new Portuguese Golden Visa applications. Don't build a residency plan around this.

Missing deadlines on non-resident tax filings. Spain's IRNR imputed income tax is an annual filing. Missing it creates penalties. The Modelo 210 reconciliation after a sale has its own deadline. Both require a Spanish tax representative if you don't have a Spanish address.

Skipping due diligence on rural and coastal properties. Coastal properties near the sea may have coastal easements (servidumbre de proteccion in Spain). Rural properties may have issues with planning permission, especially for any existing structures. Off-plan properties carry developer insolvency risk. All of these need independent legal verification before you pay any deposit.

Step-by-step checklist for UK buyers

Spain

1. Get your NIE (apply via Spanish Consulate in the UK, or via a lawyer with power of attorney)
2. Appoint an independent Spanish lawyer before paying any deposit
3. Request: title deed, land registry extract (nota simple), IBI receipts, community charges certificate, and planning certificate
4. Sign the reservation contract and pay the reservation fee
5. Open a Spanish bank account (needed before deed signing)
6. Sign the contrato de arras and pay the 10% deposit
7. Complete due diligence; resolve any title issues
8. Sign the escritura before a notary and pay ITP (or IVA + AJD for new builds)
9. Register at the Land Registry
10. Set up utilities, register for IBI, and note the IRNR filing obligation

Portugal

1. Get your NIF (via Financas in Portugal, or via a fiscal representative from the UK)
2. Appoint an independent Portuguese lawyer before paying any deposit
3. Request: land registry certificate (certidao do registo predial), caderneta predial, IMI statements, planning certificate, and any AL licence if relevant
4. Sign the reservation agreement and pay the reservation fee
5. Open a Portuguese bank account (often required in practice for larger transfers)
6. Sign the CPCV and pay the agreed deposit (10-30%)
7. Pay IMT and stamp duty before the final deed
8. Sign the Escritura before a notary
9. Complete Registo Predial transfer
10. Note annual IMI filing obligation and any AL licensing requirements

Documents you'll reuse throughout both processes: passport, proof of funds (bank statements 3-6 months), source of funds letter, tax residency certificate (from HMRC), and a power of attorney if you can't attend in person.

FAQ: UK citizens buying in Spain or Portugal

Do I need residency to buy? No. You can purchase as a non-resident in both countries. Residency is a separate legal status that involves visas and living requirements.

Do UK citizens get special treatment after Brexit? No. Since January 2021, UK nationals are treated as third-country (non-EU) nationals for most administrative and tax purposes in both Spain and Portugal. This affects non-resident tax rates, mortgage conditions, and administrative procedures.

How long does it take to get an NIE or NIF from the UK? Allow 4-12 weeks if going through the Spanish Consulate for an NIE. NIF applications in Portugal are often quicker, especially via a local fiscal representative. Many buyers overlap this with their property search rather than waiting until they've found a property.

What are the key taxes for non-residents? In Spain: IRNR (imputed income, annual), IBI (local rates, annual), and CGT at 19% on sale with 3% buyer withholding. In Portugal: IMI (annual, municipality-set), potentially AIMI (portfolio surcharge), and CGT at 28% on 50% of the net gain on sale.

If I don't rent it out, what changes? In Spain, you still owe IRNR imputed income tax on the property's notional rental value. In Portugal, you owe IMI annually regardless, but you won't have short-term rental income to complicate your tax position.

Will I need a visa to visit? As a UK citizen, you can currently visit Spain and Portugal visa-free for up to 90 days in any 180-day period (the Schengen area rules). Owning property doesn't extend this. Longer stays require a visa or residency permit.

What should I ask a lawyer before paying a deposit? Ask them to confirm: the property is free of charges or mortgages; planning permissions are in order; there are no outstanding community fees or utility debts; IBI is up to date; and (for Portugal) whether the property has an AL licence if you plan to rent short-term.

The process of buying property abroad is genuinely manageable for UK buyers, it just requires the right professionals and a clear understanding of what you owe and when. Homestra's platform covers 200,000+ properties across Europe, including a wide range of listings across Spain and Portugal, with local market data to help you compare regions before committing to the paperwork.

Whether you're looking at a villa in the Algarve or a Costa del Sol property, the full guide to buying property in Portugal is also worth reading alongside this one to understand the country-specific nuances in more depth.
