Buying a Home in Spain as an American: Arras, Notary, Registry, Taxes

Buying a home in Spain as an American takes four steps: a private contract, a public deed signed before a notary, the purchase tax, and registration at the Property Registry. The contract may carry a deposit called arras. The deed is the escritura; the Registry is the Registro de la Propiedad. The deed records your tax identification number, for an American the NIE (Ley del Notariado, article 23). The tax turns on the region and on whether the home is new. Owning it changes your yearly filings in both countries. This article is for informational purposes only and is not financial, tax or legal advice; verify current requirements with the relevant Spanish authority or a licensed professional.

What can an arras deposit cost you if the mortgage or the NIE is late?

Read the clause; the answer is there. Penitential arras (penitenciales) are a way out at a known price, and that price is your deposit: article 1454 of the Civil Code lets a sale with arras be undone by the buyer forfeiting them or the seller returning them doubled. Confirmatory arras work differently. They mark a binding contract, so the deposit isn’t a fee for walking away. Bank turns down your mortgage, or your NIE runs late? Then the contract’s other clauses decide what you lose.

In the Supreme Court’s official summaries on CENDOJ, the judiciary’s case law database, a 1996 judgment (ROJ STS 7795/1996) treats arras as confirmatory unless the will to make them penitential is unequivocal, and a 2018 judgment asks for a restrictive reading. A 2011 judgment, quoted by an appellant in a 2022 BOE resolution, says the same thing. A 1994 summary (ROJ STS 22400/1994) adds that confirmatory arras carry no right to withdraw. And what does a court award when a buyer with confirmatory arras pulls out? None of these summaries says.

Catalonia has its own rule. Article 621-8 of the Catalan Civil Code presumes confirmatory arras, and penitential ones must be agreed expressly. A buyer who withdraws loses them unless the withdrawal is justified under article 621-49. The directorate that reviews registrars’ decisions applied article 621-8 in a resolution of July 29, 2024. When does Catalan law govern a sale between two foreigners? The sources cited here don’t say.

Before you sign, check three things: the type of arras, the deed deadline, and what happens if the loan isn’t ready. The mortgage guide gives the waiting period after the bank’s binding offer, and your deadline has to leave room for it.

From offer to first property tax bill: who does what, who pays

The whole run on one table, with the bill attached to each step.

Before the arras: registry, Catastro and community checks

How to order a nota simple, the Registry’s extract, is in the rental guide. Know its limits: it’s purely informational, showing current owners, rights and charges, and only a certification proves what the Registry holds. Registration is what actually protects you. Under the Ley Hipotecaria, unregistered titles don’t bind third parties (article 32), and a good-faith buyer for value who registers keeps the property even if the seller’s title later falls for causes not in the Registry (article 34). The laws cited here set no deadline to register.

Next comes the Catastro, the state property survey. It shows anyone a property’s location, area and use, but not its owner or cadastral value, and it doesn’t cover the Basque Country and Navarre. The number that matters before you agree on a price is the reference value (valor de referencia). Article 10.2 of the transfer tax law makes it the resale tax base unless the declared value or price is higher. And under article 10.3, you can only contest it by appealing an assessment or correcting your own return. The Sede del Catastro, the Catastro’s online office, published the 2026 values on October 9, 2025. Looking one up needs identification: a DNI (the Spanish ID card) or an NIE with its support number, a digital certificate, or Cl@ve, the government login. Paper NIE certificate not working there? The Línea Directa del Catastro (91 387 45 50) gives values by phone.

Military zones are a niche case, but a real one. In zones declared restricted to foreign ownership for defense, a buyer without an EU nationality needs military authorization (Ley 8/1975, article 18 and the additional provision). This guide doesn’t list the zones.

Buying won’t get you residence anymore, either: Ley Orgánica 1/2025 removed the investor visa from April 3, 2025. A bill taxing buyers resident outside the EU at 100 percent, published on May 30, 2025, was still awaiting its consideration vote in plenary on September 28, 2026.

Buying an apartment? The unit answers for the seller’s unpaid homeowners’ community fees: the part of the current year already due, plus the 3 previous calendar years. The notary needs the community secretary’s certificate of debts, due within 7 calendar days of the request, unless you expressly waive it (horizontal property law, article 9.1.e). In Catalonia the window is the 4 previous years, reserve fund included (Catalan Civil Code, article 553-5). Unpaid IBI sticks to the property too (local finance law, article 64).

A home bought before it’s built has its own safety net. The developer must hold your payments in a special account and guarantee their refund plus legal interest by insurance or bank guarantee (Ley 38/1999). And a clause passing you the developer’s title costs or its taxes is abusive (consumer law, article 89.3).

The deed, the notary and the money trail

The notary attests four things: identity, capacity, free consent and legality (Ley del Notariado, article 17 bis). The deed also records when and how the price was paid, whether in cash, by check or by transfer (article 24). Refuse to identify the payment and the deed can’t be registered until it’s corrected (Ley Hipotecaria, article 254). Then there’s the anti money laundering law. Notaries and registrars check identity with reliable documents (article 3), ask the purpose (article 5) and must not go ahead without these checks (article 7.3). Article 6 links checks on where your money comes from to the monitoring of an ongoing business relationship, such as your Spanish bank’s; for the transfer itself, see moving money from the U.S. to Spain. Carrying 10,000 euros or more in cash into or out of Spain? You must declare it in advance (article 34).

Notary fees slide with the price. The notary tariff starts at 90.15 euros for a value up to 6,010.12 euros and drops by band to 0.3 per thousand up to 6,010,121.04 euros; above that, the fee is agreed freely. Royal Decree-law 8/2010 cuts the scale by 5 percent and requires an itemized invoice. Nice detail: under the tariff’s general rules, the notary can’t charge for advice on the deed.

Can’t make it to Spain? A consul can act as notary. The Washington consular section signs powers of attorney in person for about $60, cash or money order, according to its undated English page. The Chicago consulate’s 2026 fee table lists a general power at $35. Two posts, two prices, so ask when you book. Each consular office serves its own states. Sign before a U.S. notary instead and the power needs an apostille from that notary’s state (Washington consulate, North Carolina’s Secretary of State). The registry regulation accepts it (article 36) and lets a notary translate it or the registrar waive translation (article 37). The apostille guide covers each state.

Transfer tax, VAT and stamp duty by region

Resale or new build: that’s the fork. A resale pays ITP (Impuesto sobre Transmisiones Patrimoniales), the transfer tax, because later sales of a building are exempt from VAT (VAT law, article 20). Each region sets the rate, and where one hasn’t, the transfer tax law applies 6 percent. A new home from the developer pays 10 percent VAT instead, up to 2 parking spaces included, plus AJD (actos jurídicos documentados), the stamp duty on the deed, at 0.50 percent where the region sets none (article 31.2). The Canary Islands run their own system: a new home there pays IGIC, the islands’ sales tax, at 7 percent, or 5 percent for a main home up to 150,000 euros if you own no other home.

The rates below come from the regional pages and from Hacienda’s 2026 summary, updated September 23, 2026:

A main home can get a better deal (2026 summary):

• Andalusia: 6 percent ITP and 1 percent AJD up to 150,000 euros.
• Madrid: the ITP cut by 10 percent up to 250,000 euros.
• Valencian Community: AJD at 0.1 percent.
• Catalonia: 5 percent ITP if you’re 35 or under with taxable income up to 36,000 euros.

Navarre sets 6 percent, and an undated Bizkaia treasury answer gives 4 percent; Gipuzkoa and Álava aren’t covered here. Rates move, so check the region’s page the week you sign.

When the seller lives abroad, and the plusvalía

A non-resident seller hands you a job. You withhold 3 percent of the price and pay it on Modelo 211 within one month (non-residents tax law, article 25.2; regulation, article 14). Leave it unpaid and the property stays liable for the lower of that amount and the seller’s tax. The one exception: no withholding applies if the seller shows a tax agency certificate that they pay Spanish income or corporate tax.

Then there’s the plusvalía (IIVTNU), the town’s tax on the gain in land value. The seller owes it. But when the seller is a non-resident individual, you become the substitute taxpayer and file and pay it in the seller’s place (local finance law, article 106). Town rates go up to 30 percent. After the Constitutional Court’s ruling 182/2021, Royal Decree-law 26/2021 made the standard formula, based on the land’s cadastral value, optional. Under the local finance law (articles 104.5 and 107.5), no tax is due if the land gained no value, shown with both deeds, and a lower actual gain replaces the formula’s base. My pick if the bill lands on you: agree in the contract how the seller funds it.

Owning it: IBI, imputed income and reports in both countries

The IBI (Impuesto sobre Bienes Inmuebles) is the yearly property tax, and your town sets the rate: 0.4 to 1.10 percent of the cadastral value of urban property, or as low as 0.1 percent for up to 6 years after a general revaluation. Some towns may add up to 0.20 points, among them provincial or regional capitals and towns with public surface transport (local finance law, article 72).

Not resident yet? A home kept for your own use is taxed as imputed income anyway: 2 percent of the cadastral value, or 1.1 percent if that value was revised in the tax year or the 10 years before. U.S. residents pay 24 percent on it, with no expenses deducted (Agencia Tributaria), and file Modelo 210 during the following year. Here two official texts part ways. The agency extends the 1.1 percent to values revised since 2012 “during 2023, 2024 and 2025”. The consolidated income tax law keeps that rule for 2023 only, because Congress repealed the extending decrees. For 2026, both land on the ordinary rule above.

Once you’re resident, your main home carries no imputed income, and a second home 2 percent as a rule, or 1.1 percent after a revision on the terms above (income tax law, article 85), a case the agency’s page for residents leaves out for 2026. Bought since January 1, 2013? Then there’s no purchase deduction.

For the wealth tax, the home counts at the highest of cadastral value, official value or price, with a main home exempt up to 300,000 euros. Modelo 720, which covers real estate abroad, leaves it out. The flip side: once you’re resident, a U.S. home you keep goes on that form when your real estate abroad tops 50,000 euros; see Modelo 720 for Americans.

The U.S. side is simpler, mostly. For the IRS, foreign real estate held directly goes on neither Form 8938 nor the FBAR. The Schedule A instructions for 2025 exclude foreign real estate taxes, so IBI isn’t deductible there. Mortgage interest is murkier. Publication 936 says nothing about foreign homes, and Publication 54 treats that interest as a Schedule A item in an example that clashes with its own rule on excluded income. Ask a tax adviser.

Your next step: the nota simple, then the arras draft

Before any offer: get your NIE, open the Spanish account the price will leave from, order the nota simple and look up the reference value. Then read the draft arras contract, or pay a lawyer to read it, before a single euro of deposit leaves your account.

Do you need a lawyer? Not for the simplest purchase: a resale of a registered apartment from a resident seller, signed in person, with a clean nota simple and a community certificate. There, the notary’s checks and registration do the protecting. I’d hire one in Catalonia, with a non-resident seller, for a home bought before it’s built, when signing by power of attorney, or for an arras clause you can’t follow. For the U.S. side, get a tax adviser.
