For US citizens and green-card holders, buying a home in Spain is not just a Spanish transaction. The IRS taxes you on your worldwide income wherever you live, and a Spanish property — and the bank account behind it — brings real US reporting duties. Here is what FATCA, FBAR, the US–Spain treaty and the Spanish legal process mean for you, in plain English.
Most guides to buying property in Spain are written for buyers from the UK, Ireland or elsewhere in Europe, and they quietly assume something that is not true for you: that once you have dealt with the Spanish side, you are done. For a US citizen or green-card holder, you are never quite done, because the United States is one of only a handful of countries that taxes its citizens and permanent residents on their worldwide income regardless of where they live. You can move to Marbella, never set foot in America again, and the IRS still expects an annual return and, in many cases, information reports about your foreign assets.
That single fact reshapes the whole purchase. The Spanish steps — getting an NIE, opening a bank account, signing at the notary, paying transfer tax — are broadly the same for you as for any foreign buyer. What is different is the second, invisible layer on top: the US reporting and tax consequences of owning a Spanish home, holding a euro bank account, taking a euro mortgage, earning rental income, and one day selling. Get the Spanish side right and ignore the US side, and you can create a genuine and expensive problem with the IRS that has nothing to do with Spain at all.
Platinum Legal Spain handles the Spanish legal side of your purchase and coordinates with your US accountant on the American reporting. We are not US tax advisers and we do not file US returns — but we know exactly where the US issues sit in a Spanish transaction, and we make sure nothing on the Spanish side is structured in a way that quietly creates a US headache. With extensive experience helping expats buy in Spain, that joined-up approach is the difference between a clean purchase and a tangle of surprises.
Owning in Spain rarely changes your US tax bill on its own — but it can change what you have to report. Missing these reports, not the tax, is where Americans get into trouble.
If your foreign financial accounts together exceed US$10,000 at any point in the year, you must file an FBAR reporting every Spanish bank account you control. The buying process itself — moving a deposit into a Spanish account — can push you over the threshold. It is an information report, not a tax, but the penalties for not filing are severe.
Above higher thresholds that depend on your filing status and whether you live abroad, you also report specified foreign financial assets on Form 8938 with your return. Spanish bank accounts generally count; a directly owned home does not, but certain holding structures can. Spanish banks also report US-owned accounts to the IRS under FATCA.
As a US person you keep filing a Form 1040 every year wherever you live, reporting income from everywhere — including Spanish rental income and any gain on sale. Spain taxes the same income too, so the treaty and the foreign tax credit exist to stop you paying twice on the same euros.
The recurring theme is that the danger for American buyers is usually not double taxation — the treaty and the foreign tax credit largely handle that — but missed reporting. FBAR and FATCA are information filings, and the penalties attach to the failure to file, not to any tax owed. An American can buy a Spanish home, pay every euro of Spanish tax correctly, owe nothing extra to the IRS, and still face serious US penalties for never disclosing the euro bank account behind the purchase.
The reassuring news is that the United States and Spain have a long-standing income tax treaty, supported by the foreign tax credit mechanism in US law. Together these are designed so that income connected with your Spanish property is not taxed in full by both countries. Income from real property — including rent — is taxable where the property sits, so Spain has the first claim on your rental income and on the gain when you sell. You still report that same income to the IRS, but generally claim a foreign tax credit for the Spanish tax already paid, so the US tax is reduced or eliminated to the extent of the Spanish tax.
Two practical points follow. First, the credit is not automatic comfort — it has to be claimed correctly on your US return, and the categories, timing and limits matter, which is the work your US CPA does. Second, the treaty reduces double taxation; it does not remove the obligation to file in both countries or to keep the FBAR and FATCA reports up to date. We make sure the Spanish numbers your US accountant needs — the purchase taxes, the rental tax paid, the gain on sale — are clean, documented and available.
It is easy for Americans to assume that owning a home in Spain gives you the right to live in it. It does not. The United States is outside the EU and the Schengen Area, so as a US passport holder you are treated as a non-EU visitor. Without a visa or residence permit, you can spend a maximum of 90 days within any rolling 180-day period across the whole Schengen Area — not 90 days in Spain alone, but 90 days across all Schengen countries combined. Buying a property does not extend that allowance by a single day.
This catches a surprising number of American buyers who imagine spending five or six months a year at their Spanish home. With the 90/180 limit, that is not possible on a tourist basis — you would need a residence visa, such as a non-lucrative visa, to stay longer. The arithmetic is genuinely confusing because it works on a rolling window, and overstaying carries real consequences including fines and entry bans. We walk every American buyer through how the count works for their planned visits. Our dedicated guide to the 90/180 rule for Spanish property owners sets out the mechanics in full.
Practical friction is the part American buyers feel first. Two areas stand out: getting a Spanish mortgage, and opening a Spanish bank account as a US person. Neither is impossible, but both involve extra steps that European buyers rarely encounter.
On mortgages, some Spanish banks are cautious about lending to US citizens. Part of the reason is FATCA: taking on a US-person client brings ongoing US reporting obligations, and a number of lenders prefer to avoid the compliance burden, particularly for mortgages to non-residents. Those that do lend may offer lower loan-to-value ratios to non-resident, non-EU buyers, expect larger deposits, and ask for more documentation. It is rarely a flat "no", but it is usually a narrower market and a more paperwork-heavy process than a European buyer faces.
On bank accounts, the same FATCA logic creates the "W-9 / W-8 friction." A Spanish bank opening an account for a US person will typically ask you to certify your US status, often using the US tax forms (a W-9 for US persons, or the W-8 series in other cases) or an equivalent self-certification, so it can report the account under FATCA. This is normal — but it means account opening can take longer and some smaller banks may decline US clients. Because a functioning Spanish account is essential to complete the purchase and pay the taxes, we help American clients line this up early. The wider cost of buying property in Spain guide covers the fees side; the point here is that the banking and finance steps take an American buyer longer.
Currency is the quieter cost. You will be funding a euro purchase from US dollars, and the USD–EUR rate, plus any transfer spread and fees, can move the real dollar cost between agreeing the price and completing — so sensible buyers plan the FX rather than leaving it to chance on completion day.
Many American buyers intend to let the property when they are not using it, long-term or as a holiday rental. That is perfectly possible, but it doubles your reporting. In Spain, non-resident owners pay tax on rental income, and the rules on allowable deductions differ for non-EU residents — which, as a US person, you are. Our non-resident property tax guide covers the Spanish side, including the tax even on a property you do not rent out.
On the US side, the same rental income goes onto your Form 1040 as worldwide income, under US rules on depreciation and deductible expenses that differ from Spain's. You then claim a foreign tax credit for the Spanish tax paid on that rent, so you are not taxed twice. That mismatch on what is deductible is why a US buyer who lets a Spanish property needs both a Spanish adviser and a US CPA working from the same clean figures. We keep the Spanish records straight; your CPA fits them into the US return.
Selling as a US resident is its own subject, but it is worth understanding before you buy, because it affects how you structure the purchase. In Spain, a non-resident seller pays capital gains tax on the profit, and the buyer must withhold a percentage of the price (currently 3%) on account of your gain — money you reclaim if your actual tax is lower. The plusvalía municipal tax on the increase in land value may also apply.
On the US side, the same sale produces a capital gain reported to the IRS, calculated in dollars — which is where exchange-rate movement over your years of ownership can change the US number significantly even when the euro gain looks modest. You claim a foreign tax credit for the Spanish capital gains tax paid, and repaying any euro mortgage on the sale can separately trigger the IRC §988 currency gain. Because the dollar cost basis is fixed at purchase, getting your records right when you buy directly protects your position when you sell. Our dedicated guide to selling Spanish property as a US resident takes this further.
Buying in Spain as an American is not harder so much as it is two-sided, and the mistake we see most often is treating it as a purely Spanish transaction. The Spanish process is well-trodden and we run it for you end to end — NIE, independent due diligence, contracts, completion at the notary, taxes, registration and a Spanish will. What sets a US purchase apart is the second side: FBAR and FATCA reporting, the worldwide-income return to the IRS, the foreign tax credit, the IRC §988 currency trap and the 90/180 limit. None of those are Spanish-law questions, but all of them touch how the Spanish side should be set up.
Our role is to be the Spanish legal anchor that talks fluently to your US accountant. We act only for you — never the seller or the agent — run the purchase in plain English, and make sure the Spanish structure, banking and documentation do not quietly create a US problem. We are clear about our limits: we handle the Spanish legal side and coordinate with your US CPA on the American reporting; we are not US tax advisers and we do not file US returns. Where work goes beyond a defined scope we will tell you what it involves and quote for it. Extras may apply depending on the complexity of your matter. Our wider Spanish property legal services and the case for an independent lawyer acting only for the buyer set out how we work, and our note on the valor de referencia explains a Spanish tax-base quirk every buyer should check.
Yes. There is no restriction on Americans owning property in Spain. You will need a Spanish NIE number and a Spanish bank account, and the process is broadly the same as for any foreign buyer. The differences for US citizens are not about the right to buy — they are about the US reporting and tax obligations that come with owning a foreign asset.
Usually yes. If your foreign financial accounts together exceed US$10,000 at any point in the year, you must file an FBAR (FinCEN Form 114) listing every Spanish account you control. Above higher thresholds you may also report specified foreign financial assets on FATCA Form 8938 with your tax return. These are information reports rather than taxes, but the penalties for not filing are significant.
As a US citizen or green-card holder you are taxed by the IRS on your worldwide income wherever you live, so Spanish rental income and any gain on sale must be reported to the US as well as Spain. The US–Spain treaty and the foreign tax credit are designed so you are not taxed twice on the same income. Simply owning a home you do not rent out usually has no direct US income tax, but it can affect your reporting.
Under US tax rule IRC §988, a euro mortgage is treated as a separate dollar transaction. When you repay or refinance it, the IRS compares the dollar value of the debt when taken out against when repaid. If the euro has weakened against the dollar, you can be treated as having a taxable "gain" in dollars even though no cash reached you. Your CPA should plan for it before you take a euro mortgage.
You report the same rental income in both countries, but you should not pay full tax twice. Spain taxes the rent first because the property is there, and you then claim a US foreign tax credit for the Spanish tax paid. The deductions and depreciation rules differ between the two systems, which is why a US buyer letting a Spanish property needs both a Spanish adviser and a US CPA.
Owning the property does not give you any extra right to stay. As a US citizen you are a non-EU visitor, limited to 90 days within any rolling 180-day period across the whole Schengen Area without a visa. To spend longer — for example to live there several months a year — you would need a residence permit such as a non-lucrative visa.
Often yes, but the market is narrower. Some Spanish banks are cautious about lending to US citizens because of the FATCA reporting obligations that come with US-person clients. Those that do lend to non-resident, non-EU buyers may require larger deposits, offer lower loan-to-value ratios and ask for more documentation. It is rarely a flat refusal, but usually a more paperwork-heavy process than a European buyer faces.
Under FATCA, Spanish banks must identify and report accounts held by US persons to the US authorities. To do that they ask you to certify your US status, often using the US tax forms — a W-9 for US persons or the W-8 series in other cases — or an equivalent self-certification. It is a normal compliance step, but it can make opening an account slower, and some smaller banks may decline US clients.
For most American buyers, yes. We handle the Spanish legal side of the purchase and coordinate with your US CPA, but we are not US tax advisers and do not file US returns. The FBAR and FATCA reports, the worldwide-income return, the foreign tax credit and the currency-gain rules are US matters your accountant handles. We make sure the Spanish figures they need are clean and documented.
We strongly recommend it. A Spanish will covering your Spanish property does not replace your US estate planning, but it makes the Spanish succession far simpler and quicker for your family and avoids forcing US documents through the Spanish system after a death. It is a small step at purchase that saves real difficulty later.
On a resale property you pay Transfer Tax (ITP) at the regional rate; on a new build you pay VAT (IVA) plus Stamp Duty (AJD). On top of that there are notary, land registry and legal fees. We calculate these for your specific purchase and produce clean records of every euro paid, which your US accountant will need for the foreign tax credit. We quote for our legal work rather than applying a one-size-fits-all fee.
The sale produces a capital gain in both systems. Spain taxes the non-resident gain and the buyer withholds a percentage on account; the US taxes the same gain in dollars, where exchange-rate movement over your ownership can change the figure. You claim a foreign tax credit for the Spanish tax, and repaying a euro mortgage may separately trigger the IRC §988 currency gain. Keeping clean purchase records protects your position years later.
We run the Spanish legal side of your purchase end to end — NIE, due diligence, contracts, completion at the notary, taxes, registration and a Spanish will — acting only for you. We coordinate with your US CPA on the American reporting and flag where the Spanish structure could create a US issue. We work in plain English, serve clients across Spain, and quote clearly for work beyond a defined scope.
We handle the Spanish legal side of your purchase, coordinate with your US accountant, and make sure FATCA, FBAR, the 90/180 rule and the euro-mortgage trap are planned for — not discovered later. In plain English, across Spain.
