Buying property in Spain as a US person: comprehensive 2026 legal, tax and inheritance guide
US persons (citizens, green card holders and certain long-term residents) form a fast-growing community of Spanish property owners, particularly in Madrid, Barcelona, Marbella and Mallorca. The US-Spain interaction is uniquely complex because the US is the only major country that taxes its citizens on worldwide income regardless of residence, creating a permanent US tax footprint that overlays the Spanish residency analysis. This guide explains the Spain-US double tax convention of 1990 with its 2013 protocol (in force from November 2019 after long delays), the FATCA reporting obligations on Spanish accounts, the FBAR (FinCEN Form 114) on foreign accounts, the Form 8938 on specified foreign financial assets, the Form 3520 on foreign trusts and gifts, the US gift and estate tax with its $13.99 million 2026 exclusion versus the Spain-US gift and estate convention of 1990, the Andalusian 99% inheritance reduction interaction with US estate tax, the Beckham law for American executives, the Spanish digital nomad visa, and the practical articulation between US attorney and Spanish abogado work.

Why US persons are uniquely complex buyers
The United States taxes its citizens on worldwide income regardless of residence (citizenship-based taxation, unique in the developed world together with Eritrea). A US citizen living permanently in Spain is taxed by the IRS on all worldwide income, with foreign tax credits and the Foreign Earned Income Exclusion to mitigate double taxation. This creates a permanent US tax footprint that does not disappear with Spanish relocation. Renouncing US citizenship is the only way to break this; the renunciation triggers exit tax under section 877A for covered expatriates.
Additionally, US persons face extensive reporting obligations: FBAR for foreign accounts above $10,000 aggregate; Form 8938 for specified foreign financial assets above $50,000-$600,000 depending on filing status and residence; Form 3520 for foreign trust transactions and large foreign gifts; Form 5471 for foreign corporations; Form 8865 for foreign partnerships. Failure carries severe penalties ($10,000 to $50,000+ per form per year). Our firm coordinates with US tax attorneys and CPAs specialising in expat compliance.
Tax residency: 183-day Spanish, substantial presence US, treaty tie-breaker
Spanish tax residency: 183 days or centre of economic interests (article 9 LIRPF). US tax residency for non-citizens: substantial presence test (183 days under three-year weighted formula) or green card holder. US citizens: always US-tax resident regardless of physical presence. The Spain-US treaty article 4 provides tie-breaker rules for dual residents.
A US citizen who becomes Spanish-resident is taxed by Spain on worldwide income (Spanish IRPF up to 47% national plus regional add-ons), and continues to be taxed by the US on worldwide income (US federal up to 37% plus state tax for non-resident state filers). The treaty mitigates double taxation via the credit method: each country provides credit for taxes paid in the other, with the saving clause (article 1(4)) preserving US right to tax its citizens fully.
Modelo 720/721 reporting applies to US persons resident in Spain for US bank accounts, brokerage accounts, IRAs, 401(k)s, life policies with cash value above the €50,000 thresholds. The post-CJEU C-788/19 reform restored proportionate penalties; reporting is mandatory.
NIE, SSN and signing logistics
NIE at Spanish consulate in New York, Washington DC, Miami, Houston, Los Angeles, San Francisco, Chicago, Boston, or in person in Spain. Powers of attorney executed before a US notary public; apostille via the relevant US state Secretary of State (the US is signatory to the 1961 Hague Convention). Sworn translation to Spanish. Specificity requirements. Our NIE guide covers both routes.
US notarial documents are often less detailed than Spanish notaries require. The Spanish notary may request additional documentation: marriage certificate (apostilled and translated) for matrimonial property declaration, US driver's license plus passport for identity, US Social Security Number for tax declarations. Sending the draft documents to the Spanish notary for pre-approval prevents last-minute problems.
Anti-money laundering compliance for US buyers is rigorous: the Spanish abogado must verify source of funds, beneficial ownership, PEP status, and US sanctions (OFAC) compliance. US-citizen buyers from sanctioned categories (e.g., Russian or Iranian dual nationality) face additional scrutiny.
Acquisition taxes
Andalusian ITP 7% resale, IVA 10% + AJD 1.2% new build. Total cost 10%-13%. Our property tax guide compares regions.
There is no US federal property transfer tax. State and local transfer taxes vary widely; US buyers expecting low transfer taxes are sometimes surprised by the Andalusian 7%. Set expectations early.
IRNR for US-resident owners: the non-EU disadvantage
IRNR for US-resident owners (non-EU): 24% on imputed income (1.1%/2% catastral value) and 24% on gross rental income with NO deductibility of expenses (the non-EU penalty). A US-resident owner renting a Marbella flat for €30,000 gross with €12,000 expenses pays 24% on €30,000 = €7,200; an EU-resident owner pays 19% on €18,000 = €3,420. The US owner pays more than double. Our IRNR guide details the comparison.
In the US, the Spanish rental income is reported on Schedule E of Form 1040 with US expense deductibility and US depreciation (27.5-year residential straight-line). The treaty credit method allows credit of Spanish IRNR paid against US tax on the same Spanish-source income. The US Foreign Tax Credit basket rules (passive category) apply. Excess Spanish tax can be carried back one year or forward ten years.
The non-EU IRNR penalty makes Spanish rental property economically disadvantageous for US-resident owners compared with EU-resident owners. Structural workarounds via an EU-resident SL can be evaluated but require careful US controlled foreign corporation (CFC) analysis: a US person owning an EU SL with passive income may trigger Subpart F inclusion (immediate US taxation of CFC income) or GILTI (Global Intangible Low-Taxed Income). The CFC rules typically make corporate holding ineffective for US persons.
FATCA and FBAR on Spanish accounts
FATCA (Foreign Account Tax Compliance Act) requires Spanish banks (Santander, BBVA, CaixaBank, Sabadell, etc.) to report US account holders to the IRS via the Spanish administration under the IGA. Spanish banks routinely require US-citizen customers to complete W-9 forms and consent to FATCA reporting. Some Spanish banks refuse US-citizen customers to avoid FATCA compliance burden; finding a US-friendly bank is part of the Spanish lawyer's service.
FBAR (FinCEN Form 114) is the US person's reporting obligation for foreign accounts where aggregate value exceeds $10,000 at any time during the calendar year. Spanish current accounts, savings accounts, brokerage accounts, life policies with cash value all count. Joint accounts with non-US persons are reportable in full. Filing deadline: 15 April, with automatic extension to 15 October. Penalty for willful failure: greater of $100,000 or 50% of account balance per year; non-willful: up to $10,000 per violation.
Form 8938 (Statement of Specified Foreign Financial Assets) is filed with Form 1040 if specified foreign financial assets exceed thresholds (single US resident: $50,000 end-of-year or $75,000 at any time; married US resident: $100,000/$150,000; US-resident expat single: $200,000/$300,000; US-resident expat married: $400,000/$600,000). Spanish accounts and Spanish brokerage assets count; direct ownership of Spanish real estate does NOT count (real estate is not a financial asset), but ownership through a Spanish company does count.
Tourist rentals and the US owner challenge
Tourist licences in Andalusia: Decree 28/2016 + 31/2024. Marbella consent. Málaga moratoriums. Combined with the 24% non-EU IRNR with no deductions, tourist rentals are often uneconomic for US-resident owners. Long-term LAU rentals face the same 24% gross / no-deduction problem. For US persons, the economic case for Spanish residential property is usually personal use plus modest occasional rental rather than serious rental business.
US estate and gift tax: $13.99M exemption (2026) and the Spain-US estate treaty
US federal estate tax applies to worldwide estates of US citizens and US-domiciled residents at 40% above the basic exclusion amount, which is $13.99 million in 2026 (scheduled to halve to ~$7 million after 2025 sunset, then revised by the 2025 reconciliation legislation back to ~$15 million; subject to ongoing Congressional revisions). For estates below the exclusion, no US federal estate tax. State estate taxes apply in 12 states plus DC, with much lower thresholds (e.g., Massachusetts $2 million, Oregon $1 million, New York $6.94 million).
The Spain-US estate tax treaty of 1990 (in force from 1992) allocates taxing rights: real estate is taxable in the situs state (Spain) with US providing credit. The treaty also addresses double domicile via tie-breakers.
For a US-resident parent leaving a $500,000 Marbella flat to a child: well below the $13.99 million US exclusion, zero US federal estate tax. Spanish ISD with Andalusian 99% reduction approximately €1,000-€2,000. State estate tax (e.g., Massachusetts) potentially applies above $2 million combined estate. The combination is highly favourable for typical US estates.
For ultra-high-net-worth US families (above $13.99 million in 2026, planning for potential sunset), the Spanish property is included in the US estate but Spain credit is minimal due to Andalusian reduction. Planning techniques: GRATs, FLPs, charitable strategies on the US side; Spanish-side strategies of inheritance to multiple beneficiaries to use multiple Andalusian €1,000,000 thresholds.
US gift tax and the foreign gift reporting
US federal gift tax applies to US citizens and US-domiciled residents on worldwide gifts above the annual exclusion ($18,000 per donee in 2026, indexed; spouses can elect gift-splitting for $36,000 combined). The lifetime exclusion shares the $13.99 million estate exclusion. Spanish-situs gifts by US persons are subject to US gift tax with credit for Spanish ISD paid.
Form 3520 reports gifts received by US persons from foreign persons exceeding $100,000 from a foreign individual or $18,567 from a foreign entity (2025 threshold, indexed). A US child receiving a Marbella flat as gift from a non-US Spanish parent must file Form 3520. Failure: 5% of gift value per month, up to 25%. Many US persons are unaware of this obligation; the IRS has increased enforcement.
EU Regulation 650/2012: applicable to US person's Spanish property?
EU Regulation 650/2012 governs Spanish succession of any decedent, regardless of nationality. For US-resident decedent with Spanish-situs property: the Regulation applies, by default the law of habitual residence (US) governs, with the relevant US state law applied (since the US has no federal succession law, the relevant state's probate code applies). Article 22 allows professio iuris in favour of US nationality law, with the same state-law selection issue.
Practical complication: US state succession laws (California Probate Code, New York EPTL, Florida Probate Code, etc.) are not always familiar to Spanish notaries and registrars. The Spanish administration generally accepts US-state law via the Regulation but may request additional documentation (probate certification, executor letters, court orders) translated and apostilled. The European Certificate of Succession is theoretically issuable for US heirs but the procedure is more involved than for EU-state heirs.
Best practice: execute a Spanish will (testamento ante notario español) for Spanish assets only, with professio iuris choosing the relevant US state law of nationality (typically the state of last domicile). Execute a coordinated US will and revocable living trust for US assets, with provisions explicitly excluding Spanish assets to avoid conflict. Our inheritance guide covers the US-specific procedure.
Andalusian 99% reduction interaction with US estate tax
The Andalusian 99% reduction applies to Spanish ISD regardless of beneficiary nationality. Group I and II beneficiaries (spouse, descendants, ascendants) up to €1,000,000 per heir. For US beneficiaries inheriting Spanish property, the Andalusian reduction is fully effective on the Spanish side. The US side applies estate or gift tax on the US-citizen donor/decedent's worldwide estate, with credit for Spanish ISD paid (minimal due to Andalusian reduction). The Andalusian reduction is therefore captured by the US-citizen family only if US estate exposure is also zero (below $13.99 million exclusion) or if planned around through US estate planning techniques.
Beckham law and digital nomad visa for US executives
US executives relocating to Spain can elect the Beckham regime: 24% flat on Spanish income up to €600,000, foreign income largely exempt (subject to non-residence treatment), for six years. The 2023 reform extended access to teleworkers under Ley 28/2022 (digital nomad visa). For US tech workers earning $200,000-$500,000 in salary, Beckham combined with US Foreign Earned Income Exclusion ($126,500 in 2024, indexed) and US Foreign Tax Credit can produce significant tax savings versus US-only residency. Our Beckham law guide details the application.
The digital nomad visa under Ley 28/2022 allows non-EU teleworkers including US persons to obtain Spanish residence permits for remote work for foreign employers. Minimum income threshold (200% of Spanish minimum wage, approximately €2,762/month in 2026); US employer compliance with Spanish labour and social security rules (avoiding posted-worker treatment); FATCA and FBAR continuing for the US person.
The combination of Beckham + digital nomad visa is particularly attractive for high-earning US remote workers in Madrid, Barcelona, Valencia and Málaga. Application before six months from arrival is critical to elect Beckham; many US arrivals miss the deadline.
Capital gains: Spanish 19% (US), US worldwide, FTC credit
On sale of Spanish property by US person: 3% buyer retention (Modelo 211), 19% Spanish CGT on net gain for non-EU residents (same rate as EU on capital gains, different from rental income treatment). Refund of excess retention 6-12 months. Our sale guide covers timing.
In the US, the gain is reported on Schedule D and Form 8949 of Form 1040. Long-term capital gains (held >12 months) taxed at 0%/15%/20% depending on income, plus 3.8% net investment income tax for high earners. State capital gains tax additionally (e.g., California up to 13.3%, no special preferential rate). The treaty credit: Spanish 19% creditable against US federal capital gains tax, with passive-category FTC limitation. Excess Spanish tax can be carried back one year, forward ten years.
For US persons who used the Spanish property as principal residence for 2 of the last 5 years, section 121 of the US Internal Revenue Code exempts up to $250,000 ($500,000 for married filing jointly) of gain. This exemption applies to worldwide principal residence; a US person can use a Spanish primary residence to qualify for section 121 if the use and ownership tests are met. The exemption interacts favourably with the Spanish 19% (which may be the only material tax owed on the gain).
Practical recommendations for US buyers in 2026
Consolidated recommendations: (1) appoint independent Spanish counsel coordinated with US tax attorney/CPA; (2) plan tax residency deliberately with full understanding of US citizenship-based taxation; (3) execute coordinated US and Spanish wills with professio iuris and state-law specificity; (4) maintain FBAR, Form 8938, Form 3520 compliance annually; (5) coordinate Spanish bank choice with FATCA-friendly institutions; (6) avoid CFC traps in corporate structuring; (7) consider Beckham + digital nomad visa for remote workers; (8) plan capital gains around section 121 principal residence exemption; (9) coordinate with US estate planning for high-net-worth families; (10) review every five years and after major US legislative changes (2025 sunset of estate exclusion).
