Buying from Northern Ireland: your passport and your address are two different questions.

Most of our guides are written for people living in the Republic. A good few of the Irish buyers we talk to live in the North, and for them nearly every answer depends on two things that someone in Cork never has to pull apart: which passport you travel on, and where you live. Spain asks the first question at the airport and the second at the tax office, and the answers can point in different directions.

The buying itself is the same. The same lawyer checks, the same deposit contract, the same notary and the same purchase taxes, so everything in the six steps from offer to keys applies to you. What follows is what's different.

Your passport decides how long you can stay

Anyone born on the island of Ireland before 1 January 2005 is entitled to be an Irish citizen, and for people born since then it depends on their parents. An Irish passport makes you an EU citizen, so the 90-days-in-180 limit doesn't apply to you, there's no new border registration to do, and you can use a place in Spain for as long as you like. If you stay more than three months you register as an EU resident. That's a right, not a visa, but you'll need to show enough income or savings and health cover.

If you hold both passports, the UK government's own advice is to enter and leave Spain on the Irish one. If you only hold a British passport, you're limited to 90 days in any 180 across the whole Schengen area, owning a home there or not. That has its own guide: a British passport and a Spanish home.

Couples are often split. A husband or wife with only a British passport who moves to Spain with an Irish citizen can live there too, on a residence card for family members of EU citizens, issued for five years at first.

Your address decides the tax

This is the part most people get wrong. Spain taxes non-resident owners by where they live, not by their passport. Someone living in Dublin is an EU resident and pays Spanish non-resident tax at 19%, and if they let the place out, they pay it on the rent after expenses. Someone living in Belfast is a UK resident, so outside the EU, and pays 24%, on the gross rent, with no expenses allowed. An Irish passport doesn't change that.

The same 24% applies to the small yearly tax Spain charges on a home that isn't let, worked out from the property's cadastral value (a decree published on 7 October 2026 may change how that's worked out). The UK then taxes your rental income too, with a credit for the Spanish tax. All of it, buying, owning, selling and inheritance, is set out in the tax on both sides for UK-resident owners.

One thing to watch rather than worry about. In May 2025 the governing Socialist group put a bill to the Spanish parliament for an extra tax of 100% on homes bought by people living outside the EU. It was based on where you live, so it would have caught a buyer in Newry and not one in Dundalk. It never became law: it hadn't had its first debate when parliament was dissolved on 5 October 2026 for the 29 November election, and bills still waiting at a dissolution lapse. As drafted it didn't cover new builds bought from a developer. A new government could bring it back, and if it does we'll say so here.

Your NIE comes from Edinburgh, not Dublin

Spanish consulates work by where you live, not your passport. The Spanish Embassy in Dublin says plainly that residents of Northern Ireland have to use the Consulate General in Edinburgh, which covers Scotland, Northern Ireland and the north of England. You book by email, send copies of your documents in advance, and go in person with the EX-15 form and the 790-012 fee form. Edinburgh charges £8.65, card only, and says the NIE comes back by email in three to four weeks.

One snag: Edinburgh asks for a Council Tax bill as proof of address, and Northern Ireland has domestic rates instead. Ask the consulate what they'll accept before you book. The honorary vice-consulate in Belfast doesn't list NIEs among its services, so don't go there for one. You can also get the NIE in Spain at a police appointment, or have someone do it for you with a power of attorney. The detail is in how to get a Spanish NIE.

Signing from home

If you want someone to sign for you in Spain, the power of attorney can be signed at a Spanish consulate, or before a notary in Northern Ireland and then apostilled by the Foreign Office and translated into Spanish by a sworn translator. The UK apostille costs £45 a document on paper or £35 as an e-Apostille. The rest is in buying by power of attorney.

Paying in sterling

Buyers in the South move euro to euro. You're moving sterling, so the rate on the day matters, and on a few hundred thousand a small move in the pound is real money. A specialist currency firm will usually beat a high-street bank, and it can fix the rate ahead with a forward contract between the deposit and completion. Check the firm on the FCA register first. Your money is meant to be kept safe if a payment firm fails, but the FCA is clear that it isn't covered by the Financial Services Compensation Scheme, and a forward contract taken out to pay for a house counts as a way of paying, not an investment, so the investment protections don't apply. There's more in moving money to Spain.

Keep the paper trail. The Spanish notary records how the price was paid, and anyone carrying €10,000 or more in cash in or out of the EU has to declare it. Sterling also matters later: when you sell, the UK works out your gain in pounds, so a change in the exchange rate can create a gain on paper even if the euro price hasn't moved.

Mortgages

Spanish banks lend to non-residents, but each bank sets its own limits, and they usually lend a smaller share of the price than they would to a resident, so plan on a bigger deposit. Expect them to ask for your UK payslips, P60 and HMRC tax calculations. Spanish law gives you the same protection as anyone else: the binding offer and the draft contract at least ten days before signing, and a free private session with a notary of your choice to go through it. More in Spanish mortgages.

Healthcare on visits

Living in the North, you use the UK's GHIC, whatever your passport. The Irish EHIC is for people living in the Republic, with one exception: someone who lives in Northern Ireland but works in the Republic can get an Irish one. Either card only covers care that can't wait until you get home, in the public system, so it's not a replacement for travel insurance. If you draw a UK State Pension and move out for good, read healthcare on a UK State Pension.

Driving

A Northern Ireland licence is a UK licence, and a UK photocard licence is fine for driving in Spain on visits. If you become resident, the 2023 agreement between Spain and the UK lets you swap it for a Spanish licence without a test, and it names the DVA in Northern Ireland as well as the DVLA. The DGT says UK licence holders living in Spain can drive on their own licence for six months, so check with them how long you have when you move. The swap costs €28.87.
