Buying Property in Spain: Pitfalls Foreign Buyers Miss (2026)

Is it safe to buy property in Spain? What actually goes wrong

Buying property in Spain is safe in the sense that matters most: the deed is signed before a notary, ownership is entered at the Land Registry (Registro de la Propiedad), and foreigners — residents or not, from inside or outside the European Union — can buy on the same terms as Spaniards. The horror stories that circulate on forums are mostly about a different decade. The problems an adviser sees today are rarely about who owns the house. They are about money the buyer did not know was owed.

Almost every one of them follows the same pattern. Spanish tax law places an obligation on the buyer, or attaches a debt to the property, and nobody in the transaction has a strong reason to say so. The estate agent is paid when the sale completes. The seller wants the full price in hand. The notary authorises the deed and warns you of your duties in formal language, in Spanish, on the day of signing — when it is too late to change the numbers. The tax offices, for their part, do not warn at all: they assess, sometimes years later.

So the pitfalls of buying property in Spain are, above all, pitfalls of sequence. Each check has a moment — before the deposit contract, before the deed, within a month of the deed, every year afterwards — and a check done late is often a check that no longer protects you. The sections below follow that order. None of them is a reason not to buy. All of them are a reason to have the tax side read by someone before you sign anything that commits money.

Pitfall 1: leaving the NIE until after the deposit contract

Can you buy property in Spain without an NIE? No. The NIE (Número de Identidad de Extranjero) is the number that identifies a foreign national before every Spanish authority, and it doubles as your tax identification number. The notary must record the tax identification number of every buyer on the deed, the purchase taxes are filed under it, and without the number of every party appearing on the deed the Land Registry will not register the purchase (art. 254.2 of the Ley Hipotecaria). The defect can be remedied afterwards (art. 254.4), but until it is, the home is not registered in your name.

The pitfall is not ignorance of the NIE — most buyers have heard of it — but timing. On paper the process is quick: the NIE is governed by article 205 of the Regulation approved by Real Decreto 1155/2024, and the maximum time to resolve is 5 days from the date the application enters the register of the competent body, with administrative silence meaning refusal. In practice what takes weeks is getting to that register: an appointment at the police station or Immigration Office, or a slot at the consulate in your country of residence. Meanwhile the deposit contract (contrato de arras) has usually fixed a completion date, and the deposit is what is at stake if you cannot sign on that date.

You do not have to travel to solve it. The NIE can be obtained through the Spanish consulate where you live, or through a representative holding a power of attorney that expressly covers applying for the NIE — apostilled if it is granted outside Spain. The same power of attorney can cover signing the deed and settling the taxes, which is how many Costa Blanca purchases complete without the buyer flying over twice. One more point that saves worry: the NIE number itself never expires, so applying early costs you nothing.

What to do: apply for the NIE of every buyer — both spouses, not just one — before or at the same time as you sign the deposit contract, never afterwards. If you are buying from abroad, grant the power of attorney first and let your representative handle the application.

Pitfall 2: believing the deed price sets your tax — the Catastro reference value

This is the pitfall that produces the largest unexpected bills. Most foreign buyers assume that transfer tax is a percentage of what they pay. It is not necessarily so. Since the reform introduced by Ley 11/2021, the taxable base of ITP is the reference value (valor de referencia) published by the Dirección General del Catastro, and the declared price only if that price is higher (art. 10.2 of the consolidated ITP and AJD act, TRLITPAJD). In other words: you pay on the higher of the two, and a low agreed price does not lower the tax.

The reference value is fixed yearly for every property from the prices notaries report on completed sales, by homogeneous valuation zones. It is not a valuation of your particular house. Nobody visited it; its state of repair, its tenants and its defects played no part in the calculation. That is exactly why it bites on the Costa Blanca, where a dated apartment that needs rewiring sells well below what the zone average suggests. It is also not the cadastral value printed on the IBI receipt — they are two different figures with two different jobs, and we come back to that confusion below.

You cannot negotiate the reference value before paying, and there is no appeal in advance. The law expects you to self-assess on the reference value and then, if you believe it exceeds the real market value of the home, request rectification of your own self-assessment with a refund of the undue payment (art. 120.3 of the General Tax Act, LGT). The tax office resolves after a preceptive and binding report from the Catastro, and you have four years to ask (arts. 66.c and 67.1 LGT). What you should not do is self-assess on the price and wait to be corrected: declaring below the reference value produces an assessment for the difference, with interest, and you lose the clean procedural position that a rectification request gives you.

What to do: before you agree a price — and certainly before you sign arras — look up the reference value of the property on the Sede Electrónica del Catastro using its cadastral reference, and budget your ITP on the higher figure. If the gap is large and the condition of the property justifies it, plan the rectification request from day one: a homologated valuation and builder quotes are the evidence that wins it.

Pitfall 3: hidden costs of buying property in Spain — budgeting only the price

How much tax do you pay on buying property in Spain? It depends first on what you buy. A resale home bought from a private owner pays Transfer Tax (ITP), and in the Comunidad Valenciana the general rate is 9% for purchases accruing from 1 June 2026, under article 13.Uno of Ley 13/1997 as amended by Ley 5/2025. Websites still quoting 10% are citing the wording that applied until 31 May 2026. Reduced rates exist, but only for the habitual residence of narrowly defined groups — under-35s, large or single-parent families, people with a disability, victims of gender violence, protected housing — so a non-resident buying a holiday home should not count on them.

A new-build bought from a developer pays 10% VAT (IVA) instead of ITP, plus stamp duty (AJD) on the deed. In the Comunidad Valenciana the AJD rate is 0.1% when the home will be the buyer’s habitual residence and 1.4% in all other cases — and a holiday home, a rental or an investment is one of the other cases. The two regimes are mutually exclusive: you never pay ITP and VAT on the same purchase. The pitfall is comparing a resale and a new-build by their asking prices alone, when the tax on top is different, and then discovering at the notary which one applies. Asset type matters too: plots of land and commercial premises can attract 21% VAT, so a garage or a plot sold alongside a home deserves its own question.

Then come the costs that are not taxes: the notary, whose fees follow a national regulated tariff; the Land Registry, to inscribe your ownership; the gestoría that files the taxes and lodges the deed; a valuation if there is a mortgage; and the NIE. None of them is large next to the purchase tax, but together they are the reason buyers who transferred exactly the price from the UK find themselves short on signing day. And because ITP is self-assessed on modelo 600 within 30 working days of the deed — Saturdays, Sundays and public holidays do not count — the money for the tax must be in Spain and available almost immediately after completion, not some months later.

What to do: ask for the full cost as one closed number before you commit — purchase tax on the correct base, notary, registry, gestoría, NIE and, where relevant, the amounts you will have to withhold from the seller (next two sections). This is what a conveyancing tax service exists to produce, and it is worth far more before arras than after.

Pitfall 4: the 3% retention when the seller is non-resident (modelo 211)

On the Costa Blanca a large share of sellers are themselves foreigners who do not live in Spain. When the seller is a non-resident without a permanent establishment, Spanish law does something that surprises every first-time buyer: it makes the buyer a tax collector. Any acquirer — resident or not, individual or company — must withhold 3% of the agreed price and pay it to the Spanish Tax Agency (AEAT) on modelo 211 (art. 25.2 of the Non-Resident Income Tax Act, TRLIRNR). The 3% is not an extra cost: it comes out of the price, as an advance on the tax the seller owes on the gain, which for any non-resident seller is 19%.

The pitfall is in who carries the risk. The obligation is the buyer’s, not the seller’s and not the notary’s. If you pay the seller the full price and the 3% never reaches AEAT, the property you have just bought answers for the lower of the retention and the seller’s tax, and the Registrar enters a marginal note to that effect (art. 25.2 TRLIRNR; art. 14.5 of the IRNR Regulation, RIRNR). By then the seller has the money and has left Spain. The deadline is one month from the deed (art. 14.3 RIRNR; art. 8.5 Orden EHA/3316/2010), and once you have filed you hand the seller a copy, which they need to claim any refund.

Two details avoid most mistakes. First, the base is 3% of the agreed price in the deed — not the Catastro reference value, which only governs your own ITP. Second, there is a single way out: no retention is due only when the seller proves, with an AEAT certificate, that they are subject to Spanish personal income tax (IRPF) or corporate tax (art. 14.2 RIRNR). A Spanish address, a Spanish bank account, a TIE card or the seller’s word are not that certificate. The certificate is dated, so ask for one issued for the current year that names the person who signs the deed.

What to do: establish the seller’s tax residence before arras, write the retention into the deposit contract so nobody argues at the notary, have the 3% held back at completion, and file modelo 211 within the month. Do not wait for the seller’s lawyer to remind you — the seller has no incentive to chase a form that only reduces the cash they receive.

Pitfall 5: plusvalía municipal — who really pays when the seller lives abroad

Who pays the plusvalía when buying in Spain? On a sale, the seller. Plusvalía municipal (formally the IIVTNU) is a town-hall tax on the increase in the value of the urban land between acquisition and transfer (art. 104.1 of the Local Finance Act, TRLRHL); the building is irrelevant. Each ayuntamiento sets its own coefficients and its own rate in its ordenanza fiscal, never above 30% (art. 108.1), and since Constitutional Court ruling 182/2021 and Real Decreto-ley 26/2021 the taxpayer pays on the lower of two methods — objective or real gain — and pays nothing if there was no gain.

So far, not the buyer’s problem. It becomes the buyer’s problem in precisely the situation of the previous section: when the seller is a non-resident individual, the buyer is the substitute taxpayer (art. 106 TRLRHL). That means the town hall can look to you, the new owner with a property in its municipality, rather than chase someone who now lives in another country. A clause in the contract saying that the seller pays the plusvalía is valid between the two of you, and it is the normal arrangement; what it does not do is bind the ayuntamiento.

Buyers also get caught by negotiation. Liability for the plusvalía can be shifted by contract, and in a seller’s market it is sometimes slipped into the reservation document as a line nobody explains. Because the amount depends on the cadastral land value, the years of ownership and the ordinance of that particular town, it cannot be guessed from the price — it can be modest in one case and substantial in the next.

What to do: have the plusvalía calculated for the specific town hall before arras. If the seller is a non-resident, agree in the contract that the estimated amount is held back from the price at completion and paid directly to the ayuntamiento, with any difference settled afterwards, and keep proof of payment with your deed.

Pitfall 6: IBI debts and charges that follow the property

In Spain some debts belong to the property rather than to the person who ran them up. IBI — the annual municipal property tax — is the clearest example. The property itself answers for unpaid IBI, in subsidiary liability, whoever owns it now (art. 64.1 TRLRHL and art. 79.1 LGT), and those debts stay claimable for four years (art. 66.b LGT). A buyer who does not ask for a debt certificate before signing can receive, long after completion, a demand for years in which they had never set foot in the house.

The second IBI pitfall is the year of the sale. The tax accrues on the first day of the calendar year and the holder on that date owes all twelve months (art. 75 TRLRHL). The law provides no proration for a sale, so any split of the year between seller and buyer is a private clause in the deed (art. 63.2), not something the town hall recognises. The receipt will be issued in the seller’s name; if the seller simply does not pay it, the ayuntamiento can still pursue the property in your hands.

Registered charges work on the same logic but are easier to see: a mortgage, an embargo or an annotation appears on the nota simple from the Land Registry. The pitfall is relying on a nota simple obtained when the property was first listed. It should be requested again close to the deposit contract and the position confirmed again at completion, when any outstanding mortgage of the seller is cancelled out of the price.

What to do: obtain an up-to-date nota simple, the latest IBI receipt and a certificate that there are no outstanding IBI debts before you sign arras. In the deed, say explicitly how the current year’s IBI is shared, and if any debt exists, have it paid or withheld from the price at the notary.

Pitfall 7: signing the deposit contract (arras) before checking anything

Most of the checks in this guide are cheap, quick and decisive — and most buyers carry them out after paying the deposit, which is backwards. The contrato de arras is the moment at which you commit real money and fix a completion date. Everything that could change the price you are willing to pay, or the amount the seller will actually receive, should be known before it is signed: the reference value, the seller’s tax residence, the plusvalía estimate, the IBI position, the charges on the registry.

Add to that list the documents of the property itself. The usual file for a sale includes the seller’s title deed, the latest IBI receipt and the cadastral reference, the energy performance certificate, and a certificate from the community of owners confirming that the seller is up to date with community fees. On an urbanisation with a pool and gardens those fees are not trivial, and the certificate is the simple way of not inheriting an argument with your new neighbours. In the Comunidad Valenciana the seller also needs the habitation certificate to transfer the home.

A well-drafted deposit contract then turns what you have found into clauses: the price, the completion date and who attends or signs by power of attorney; the 3% retention if the seller is non-resident; how the plusvalía is handled; how the year’s IBI is split; the seller’s duty to deliver the property free of charges, tenants and debts, with the certificates to prove it. None of this is exotic. It is simply easier to agree while both sides still want the deal than at the notary’s table.

What to do: treat the reservation or arras document as the real contract, because it is. Have the tax side reviewed before you sign it, not between arras and completion.

Pitfall 8: forgetting modelo 210 — the annual non-resident tax on an empty home

Do you have to pay non-resident tax in Spain if the house is empty? Yes. Every non-resident who owns urban property in Spain must file modelo 210 — the Non-Resident Income Tax (IRNR) return — each year, even if the home is never let and generates no income whatsoever. The law imputes an income to a home kept for your own use: 1.1% or 2% of the cadastral value, depending on whether the municipality’s cadastral values have been revised recently enough. The tax rate applies to that small base, never to the full cadastral value.

The rate is 19% for residents of the European Union, Iceland, Norway and Liechtenstein, and 24% for the rest of the world, British owners included since Brexit. The amounts are modest, and that is part of the pitfall: nobody sends a bill, nothing is deducted at source, and AEAT does not remind you. The obligation is born with the purchase, runs for every day of ownership in the year, and is entirely self-assessed. Owners typically find out when they come to sell and the missing years surface.

The calendar has also just changed, which is catching out people who did know about the tax. Under Orden HAC/623/2026, deemed income for 2025 is filed up to 31 December 2026, but for income accrued from 2026 onwards the window runs from 1 April to 31 December of the following year — the 2026 return cannot be filed until 1 April 2027. If you let the property instead, you declare the rent on modelo 210; only residents of the EU, Iceland, Norway and Liechtenstein may deduct expenses, and everyone else is taxed on the gross rent.

Catching up voluntarily is far cheaper than being found. Filing late of your own accord carries a surcharge of 1% plus a further 1% for each full month of delay, or 15% after twelve months, reduced by 25% and with no penalty. What to do: diarise the first modelo 210 on the day you complete, keep the IBI receipt (it shows the cadastral value the calculation needs), and if you would rather not think about it again, hand the annual return to an adviser.

Pitfall 9: buying jointly and filing one modelo 210 instead of one per owner

Modelo 210 is an individual return. The rule is one return per owner and per property, so a married couple owning one home 50/50 files two modelo 210 returns a year, each for half of the base. Spain has no joint filing for non-residents, and the fact that the couple files a joint return at home changes nothing here. A couple who owns an apartment and a separately registered garage, each with its own cadastral reference, is looking at four returns.

The typical mistake is a single return in the name of whichever spouse dealt with the purchase, declaring 100% of the property. It feels compliant — the tax has been paid in full — but in AEAT’s records one owner has over-declared and the other has never filed at all. The gap tends to surface at the worst time: on a sale, when each seller’s position is looked at separately, or on an inheritance, when the surviving spouse discovers that the deceased had years of unfiled returns.

Joint ownership also interacts with residence. The rate follows the country of tax residence of each owner, not the property. If one co-owner lives in Ireland and the other in the United Kingdom, one half is taxed at 19% and the other at 24%. And if, years later, one owner moves to Spain and becomes tax resident while the other stays abroad, only the one who stays continues with modelo 210.

What to do: decide the ownership split deliberately before the deed, because it is recorded there and it drives every later tax — and from the first year file one modelo 210 per owner, per property.

Pitfall 10: tax letters sent to an empty house — the fiscal representative outside the EU/EEA

Few services are sold to foreign buyers with as much fear as the fiscal representative, and the law is narrower than the sales pitch. Article 10.1 TRLIRNR contains a closed list: the duty to appoint a representative resident in Spain falls on taxpayers who are not resident in another EU Member State, and only in the cases the article sets out — among them, when the Tax Agency expressly requires it, or when you reside in a territory with no effective exchange of tax information. Where the duty applies, failing to appoint is a serious infringement with a fixed fine of €2,000, or €6,000 for residents of territories with no effective exchange of information. Residents of the EU, and of EEA states with mutual-assistance arrangements, are outside the duty and act through ordinary representation rules.

The real pitfall is a different rule that applies to everyone. Without a representative, your fiscal domicile for income from the property is the property itself (art. 11.1.b TRLIRNR). That is where AEAT sends its letters — to a holiday home that is shut for most of the year. After two failed delivery attempts the Tax Agency publishes a notice in the BOE, and 15 days later the assessment is deemed notified for all legal purposes (art. 112 LGT). It becomes final, the period to appeal runs out unnoticed, and the debt moves to enforcement with surcharges.

For an owner who lives outside the EU/EEA — in the United Kingdom, for example — this is the honest reason to appoint someone in Spain: not a slogan about what is compulsory, but having a Spanish address where notifications are actually received, read and answered in time, and having someone whose job is to check whether your situation falls into one of the article 10 cases. For an EU resident it is a convenience rather than a duty, and for many owners with a locked-up apartment it is a convenience worth having.

What to do: decide at the time of purchase where the Tax Agency will write to you, and make sure that letters sent there will be opened. If you live outside the EU/EEA, have your article 10 position checked rather than assumed.

Pitfalls of buying property in Spain from the UK after Brexit

Can a British citizen still buy property in Spain? Yes — with no restriction on the purchase itself, and paying exactly the same purchase taxes as anyone else. ITP, VAT and AJD do not look at nationality or residence, except that reduced rates reserved for a habitual residence will not apply to a holiday home.

What changed with Brexit is the tax life of the property after the purchase. The United Kingdom is neither an EU member state nor part of the European Economic Area, so British owners apply the 24% rate on modelo 210 rather than 19%, and if they let the property they are taxed on gross rent, with no deduction of expenses. The 2013 Spain–UK double tax treaty remains in force and prevents the same income being taxed twice, but it does not reduce the Spanish domestic rate. On a future sale the gain is taxed at 19% for every non-resident, EU or not.

Two practical points complete the picture. A UK resident is, by definition, a taxpayer not resident in another EU Member State, so the fiscal representative question in the previous section is a live one and deserves a proper answer rather than a guess. And buying a home does not, on its own, give you the right to live in it all year: the purchase and your immigration status are separate matters, and the NIE is an identification number, not a residence permit.

What to do: budget the ongoing tax at the rate for residents outside the EU/EEA from the outset, particularly if the plan depends on rental income, and keep the UK and Spanish returns consistent with each other so that the treaty relief works as intended.

Cadastral value vs reference value: the mix-up behind wrong tax bills

Two Catastro figures with similar names sit behind most of the taxes in this guide, and confusing them is a pitfall in its own right. The cadastral value (valor catastral) is the figure printed on your IBI receipt. It drives the IBI itself (art. 65 TRLRHL), the imputed income on modelo 210 — that 1.1% or 2% — and the wealth tax base. The reference value (valor de referencia) is a separate figure, published yearly, that drives the base of transfer tax when you buy and of inheritance and gift tax.

They are distinct items in the cadastral description of the property, and correcting one does not correct the other. Quoting the reference value in a modelo 210, or the cadastral value in a modelo 600, is how a filing ends up wrong in either direction. Nor does the reference value follow you around afterwards: a purchase taxed on a high reference value does not give you a high acquisition cost for a future capital gain — that is governed by what you actually paid.

A third figure to keep apart is the agreed price in the deed, which is the base of the 3% retention on modelo 211. Three numbers, three uses: the price for the retention, the higher of price and reference value for your ITP, the cadastral value for IBI and the annual modelo 210.

What to do: keep a one-page record of the property with its cadastral reference, cadastral value (and the year of the municipality’s last revision), reference value at the date of purchase and deed price. Every tax in the life of the property starts from one of those four lines.

New rules for buying property in Spain in 2026: what changed and what did not

Searches for new rules on buying property in Spain spike every time a proposal makes the news. For a buyer on the Costa Blanca, the changes that are actually in force and that alter the numbers are three. The general ITP rate in the Comunidad Valenciana is 9% for purchases accruing from 1 June 2026, down from the 10% that applied until 31 May 2026 (Ley 5/2025, amending Ley 13/1997). The modelo 210 calendar for deemed income has moved: from 2026 accruals onwards, the return is filed between 1 April and 31 December of the following year (Orden HAC/623/2026). And the NIE has a new legal home in article 205 of the Regulation approved by Real Decreto 1155/2024, the previous regulation having been repealed since 20 May 2025.

What has not changed is everything else in this guide: the reference value as the ITP base, the buyer’s 3% retention, the rules on plusvalía and IBI, and the 19%/24% split on modelo 210. Be wary of dates and percentages quoted from memory — many Costa Blanca websites and estate agencies still publish the old ITP rate and the old filing calendar. Always check the accrual date of your own purchase before trusting a figure.

What to do: ask whoever gives you a number which law it comes from and from what date it applies. A rate without a date is a guess.

Who checks what: estate agent, notary, lawyer and tax adviser

A last, structural pitfall is assuming that someone in the transaction is already looking after all of this. The estate agent markets the property and brings the parties together; the agent’s commission is normally paid by the seller. The notary verifies identity and capacity, authorises the deed and informs you of your tax duties, but does not calculate your taxes, file modelo 211 for you or check the plusvalía ordinance of the town. The Land Registry registers what it is sent. A lawyer looks at title, charges and the contract. The tax numbers — base, rate, retention, plusvalía, the first modelo 210 — belong to whoever you have expressly asked to own them.

That is the work we do for buyers on the Costa Blanca: the all-in cost as a single number before arras, every purchase tax filed with the authorities, coordination with the notary and the registry, the special tax position when the seller is non-resident, the NIE, and the annual non-resident return from the first year. The conveyancing tax service costs 1% + VAT of the price, with a minimum of €1,000 + VAT; the annual modelo 210 is €119 + VAT per property per year, and acting as your tax representative with AEAT is €149 + VAT per year. Notary and registry fees and the taxes themselves are paid by the client and are not included. A chartered economist reviews each transaction; we work in Spanish, English and Russian.

What to do: whoever you use, ask one question before you sign anything — who, by name, is responsible for each line of the checklist below. If the answer to any line is silence, that line is your pitfall.
