US Expat Taxes in Spain

Who Has to File: Your US Obligations from Spain

The United States taxes its citizens and green card holders on worldwide income no matter where they live. Moving to Spain does not end your relationship with the IRS. If your worldwide income exceeds the standard filing threshold (for 2026, $16,100 for single filers, or just $5 of income if you are married filing separately — common when your spouse is a Spanish citizen with no US status), you must file Form 1040 every year.

Filing does not usually mean paying. Because ordinary Spanish tax rates are high by US standards, the majority of Americans in Spain owe the IRS nothing after applying the Foreign Tax Credit or the Foreign Earned Income Exclusion. But the return itself, plus the information reports that travel with it — FBAR, Form 8938, and potentially Forms 8621, 3520, or 5471 — are mandatory, and the penalties for skipping the information forms dwarf anything tied to the tax itself.

There is one important twist in Spain: the Beckham regime. Americans who elect it pay much less Spanish tax, which can leave real US tax owed rather than the usual zero. And on the Spanish side, residence makes you subject to Spanish tax on worldwide income (unless you are under Beckham), plus the wealth and Solidarity taxes and the Modelo 720 asset declaration. You will deal with two administrations each year: the IRS and the Agencia Tributaria (Hacienda). The rest of this guide walks through how the two systems interact and where Americans most often get hurt.

How Spanish Income Tax Works in 2026

Spain's personal income tax (Impuesto sobre la Renta de las Personas Fisicas, or IRPF) is progressive and, crucially, shared between the central state and the seventeen autonomous communities. Roughly half the schedule is set nationally and half by the region where you live, so your combined marginal rate depends on where in Spain you reside.

General income — salary, self-employment, rental, and pensions — is taxed on a combined state-plus-regional scale. Entry rates begin near 19% and rise progressively; top combined marginal rates run from about 45% in lower-tax regions to 50%-54% in higher-tax communities such as Catalonia, Valencia, and the Balearics. There is no single national top rate — two Americans earning the same salary in Madrid and Barcelona can pay noticeably different Spanish tax.

Savings income — interest, dividends, and capital gains — is taxed separately on its own progressive scale:

• 19% up to EUR 6,000
• 21% from EUR 6,000 to EUR 50,000
• 23% from EUR 50,000 to EUR 200,000
• 27% from EUR 200,000 to EUR 300,000
• 30% above EUR 300,000

On top of income tax, most residents face wealth tax and, for large fortunes, the Solidarity Tax (covered below). For US purposes the key fact is that Spanish IRPF — both the state and regional portions — is a creditable foreign income tax on Form 1116. Wealth tax, the Solidarity Tax, IVA (VAT), and Spanish social security contributions are not creditable income taxes.

Spain vs United States: Side-by-Side 2026 Tax Comparison

The two systems look alike on the surface and diverge everywhere that matters. Check the item you care about before you plan a move, a sale or a drawdown.

• Tax year: both use the calendar year, but Spain has no split year, so crossing 183 days makes you resident for all 12 months.
• Filing window: Spain files through Renta Web from early April to June 30; the US is due April 15, June 15 for expats and October 15 on extension.
• Income scale: Spain runs a state scale topped up by the regions, giving 2026 combined rates from 19% to about 45% in Madrid, 47% in Andalusia, 50% in Catalonia and 54% in Valencia; the US runs 10% to 37% federally, with 37% starting at $640,600 single and $768,700 joint.
• Savings income: Spain taxes interest, dividends and gains at 19%, 21%, 23%, 27% and 30% above EUR 300,000 with no holding-period discount; the US taxes long-term gains at 0%, 15% or 20% plus 3.8% net investment income tax.
• Joint filing: the US doubles the brackets for couples; Spain only offers tributacion conjunta, which trims the base by EUR 3,400, so most two-income couples file separately.
• Allowances: Spain gives a personal minimum of EUR 5,550 plus family minimums; the US standard deduction is $16,100 single and $32,200 joint for 2026.
• Retirement saving: Spain allows EUR 1,500 a year into a plan de pensiones plus EUR 8,500 of employer contributions; the US allows $24,500 into a 401(k) and $7,500 into an IRA for 2026.
• Social charges: Spanish employees pay about 6.5% and autonomos EUR 200 to EUR 590 a month; US employees pay 7.65% and the self-employed 15.3%, with no totalization agreement to pick one.
• Wealth: Spain taxes net worth above EUR 700,000 in most regions and above EUR 3 million nationally; the US has no wealth tax.
• Inheritance and gifts: Spain taxes the recipient under regional rules, with Madrid and Andalusia granting a 99% reduction for close family and Catalonia and Asturias charging in earnest; the US taxes the estate only above $15 million in 2026 and ignores gifts under $19,000 per recipient.
• Foreign asset reports: Modelo 720 and 721 above EUR 50,000 per category; FBAR above $10,000 and Form 8938 above $200,000 for expats.

The Beckham Law: Why Spain's Best Tax Break Can Be a US Trap

The Beckham Law (formally the regimen especial de trabajadores desplazados, or impatriate regime) is Spain's headline incentive for skilled arrivals. Qualifying newcomers who have not been Spanish tax residents in the prior years can elect to be taxed as non-residents for the year of arrival plus the following five — up to six years in total.

Under the regime, Spanish-source employment income is taxed at a flat 24% up to EUR 600,000 (47% above that), and, critically, most foreign-source income — foreign dividends, interest, and capital gains — is generally not taxed by Spain at all. The Startups Law (Ley de Startups) broadened access from 2023 to include certain remote workers, entrepreneurs, and highly qualified professionals.

For a Spaniard or other non-American this is a straightforward win. For a US citizen it can quietly backfire, and this is the single most important planning point in this guide.

Less Spanish tax means less Foreign Tax Credit

The US taxes your worldwide income regardless of Beckham. Your defense against double tax is the Foreign Tax Credit — but the credit is only as large as the Spanish tax you actually pay. A flat 24% is well below the US marginal rates a high earner faces, and untaxed foreign income generates no Spanish tax to credit at all. The result: an American on the Beckham regime can owe substantial US tax, where an ordinary Spanish resident at 45%-plus rates would owe the IRS nothing and bank an excess credit.

The non-resident status complicates the treaty

Beckham electees are taxed under Spain's non-resident rules. That can undercut a claim to be a treaty resident of Spain, which matters for how certain income is sourced and relieved. Before electing Beckham, an American should model the combined US-plus-Spanish outcome both ways — the regime that saves a colleague thousands can cost you more.

Spanish Tax Residency: When Spain Taxes Your Worldwide Income

Spain treats you as a tax resident, and taxes your worldwide income, if any of three tests is met in a calendar year:

• You spend more than 183 days in Spain during the calendar year (sporadic absences count toward the total unless you prove tax residence elsewhere).
• Your main center of economic interests or activities is in Spain.
• Your spouse (not legally separated) and dependent minor children are habitually resident in Spain — a presumption you can rebut.

Unlike the US, Spain's year is the calendar year and there is generally no split-year treatment: if you cross the 183-day line, you are treated as resident for the whole year. This makes your year of arrival critical for planning, and it interacts with the Beckham election, which must be made within a set window after starting work in Spain.

Spanish residence brings three parallel obligations beyond income tax: the Modelo 720 foreign-asset declaration, wealth tax in most communities, and potentially the Solidarity Tax. Because the US taxes you as a citizen and Spain taxes you as a resident, you are inside two worldwide-taxation systems at once. Being a Spanish tax resident — or even a Spanish treaty resident under the tie-breaker — does not release you from US filing, because of the treaty's saving clause. Move-year returns, where you are part-year resident of both countries and possibly electing Beckham, are the most error-prone filings we see from Americans in Spain.

Digital Nomad Visa, Non-Lucrative Visa and Golden Visa: Tax Consequences

Your visa decides whether you may live in Spain, not whether Spain taxes you. The 183-day and centre-of-interests tests decide that, and every long-stay visa expects you to spend most of the year in Spain, so tax residence follows within your first full calendar year. The one variable you control is the arrival date: land after July 2 and you stay non-resident for that year, the window to sell appreciated US assets and do Roth conversions, since Spain gives no step-up and does not recognise Roth accounts.

Digital Nomad Visa

The DNV under the Startups Law admits remote employees of a non-Spanish company and freelancers who earn no more than 20% of their income from Spanish clients, with a minimum income of roughly EUR 2,800 a month tied to the Spanish minimum wage. It runs for one year, renewable to five, and the holder can elect the Beckham regime: a flat 24% on employment income and no Spanish tax on foreign dividends, interest or gains. That election is what makes the DNV interesting for Americans and also where the US tax trap lives, so read the Beckham section and our dedicated Beckham guide first. Two catches: freelancers on the DNV generally cannot elect Beckham, and a US employer with an employee in Spain must arrange Spanish social security coverage, because no totalization agreement keeps you on US coverage.

Non-Lucrative Visa

The NLV is the retiree route. You show passive income of about EUR 2,400 a month for the main applicant and you may not work, including remotely for a US employer. Because renewal requires more than six months a year in Spain, you become tax resident and pay progressive IRPF on worldwide income: US Social Security as explained above, IRA and 401(k) withdrawals as general income, dividends and gains on the savings scale, plus wealth tax on the accounts themselves. Beckham is not available. The Foreign Tax Credit usually wipes out the US bill, but nothing offsets Spanish tax on a Roth withdrawal, so take Roth money out before you arrive.

Golden Visa

Spain closed the investor Golden Visa on April 3, 2025. Holders who applied before that date keep renewing, and because the visa never required physical presence many stay non-resident and pay only non-resident tax on their Spanish property. Anyone buying now needs the NLV or the DNV, and both lead to full Spanish residence.

The US-Spain Tax Treaty and Its Limits

The US-Spain income tax treaty was signed in 1990 and entered into force that year. A significant Protocol, signed in 2013, entered into force on November 27, 2019 and substantially modernized the investment articles — cutting withholding on many dividends, interest, and royalties toward zero and updating dispute-resolution and information-exchange provisions.

The treaty allocates taxing rights between the two countries: employment income is generally taxable where the work is performed, portfolio dividend withholding is capped (generally at 15%), and after the 2013 Protocol most interest and royalties are taxed at 0% at source. Pensions and government service have their own rules.

But every American must understand the saving clause: the treaty lets the United States tax its own citizens as if the treaty did not exist, with only narrow, listed exceptions. In practice the treaty rarely reduces a US citizen's IRS bill directly. Its real value is ordering the two systems — deciding which country taxes an item first, so the other grants a credit — and making Spanish tax a legitimate creditable tax.

Two Spain-specific cautions. First, the treaty is an income tax treaty; it does not relieve Spanish wealth tax or the Solidarity Tax, which are taxes on capital. Second, there is no accompanying totalization agreement, so the treaty does nothing for social security or self-employment tax coordination. Some treaty positions must be disclosed on Form 8833; claiming benefits incorrectly, or failing to disclose, is a common error in self-prepared expat returns.

FEIE vs Foreign Tax Credit: It Depends on Beckham

Americans abroad have two main tools against double taxation: the Foreign Earned Income Exclusion (FEIE, Form 2555), which excludes up to $132,900 of earned income for 2026, and the Foreign Tax Credit (FTC, Form 1116), which credits foreign income taxes against US tax dollar for dollar.

For an ordinary Spanish tax resident, the FTC is usually the better answer. Combined state-plus-regional IRPF rates exceed US rates at most income levels, so Spanish tax paid typically wipes out the US liability and generates excess credits that carry forward up to ten years. The FTC also keeps your income eligible for the refundable Additional Child Tax Credit — worth up to $1,700 per child in 2026 even with zero US tax owed — which the FEIE forfeits.

The Beckham exception

Under the Beckham regime the analysis inverts. Spanish tax on employment income is a flat 24%, often below the US effective rate, and foreign income is untaxed by Spain — so there may be little or no Spanish tax to credit. Here the FEIE can shelter the first $132,900 of earned income, but income above that, and passive income, can leave real US tax owed. Beckham filers frequently need a careful blend of FEIE, the housing exclusion, and FTC on any Spanish tax that does apply.

Be careful switching methods: once you claim the FEIE and revoke it in favor of the FTC, you generally cannot re-elect the FEIE for five years without IRS consent. Run the comparison both ways before the first return you file from Spain, not after.

Social Security: No Totalization Agreement With Spain

This is one of the most important and least understood facts for Americans in Spain: the United States and Spain have NO totalization agreement. Most major expat destinations — Germany, France, the UK, Italy — have one; Spain does not.

The consequences are real and directly financial.

• Self-employed Americans (autonomos) generally owe both Spanish social security contributions and the 15.3% US self-employment tax on the same earnings. There is no certificate of coverage available to exempt you from the US charge, because the exempting mechanism lives in a totalization agreement that does not exist. Where a freelancer in Germany can eliminate the US SE tax entirely, a freelancer in Spain usually cannot.

• Employees posted between the two countries can face periods of dual social security coverage, with no agreement to assign coverage to one system or to combine credits toward benefit eligibility.

Spanish social security contributions are not creditable as income taxes on Form 1116 — they are social charges, not income tax. They may, in limited situations, factor into deductions, but they do not offset US tax the way Spanish income tax does. For self-employed clients, the missing totalization agreement is often the largest single US cost of living in Spain, and it needs to be built into any move budget and, where possible, into entity and compensation planning.

Spanish Pensions and US Taxes: Planes de Pensiones and the State Pension

Spanish retirement vehicles do not map cleanly onto US tax categories, and this is where Americans in Spain often need professional help.

• Spanish state pension (pension de la Seguridad Social): contributions are Spanish social charges; benefits are pension income. Under the treaty's pension and social security articles, sourcing depends on the type of payment and the recipient's residence, read together with the saving clause.

• Planes de pensiones (private pension plans) and PPAs: these are tax-deductible in Spain within annual limits, but they are generally not qualified plans for US purposes. Growth may be currently taxable to the US owner, employer or personal contributions are not US-deductible, and — most damaging — the plan almost always invests in Spanish or EU funds that are PFICs, dragging Form 8621 into your return. Depending on structure, foreign-trust reporting on Forms 3520/3520-A can also be triggered.

• Employer and collective plans (planes de empleo): treatment depends on structure; many are effectively foreign pension trusts or annuity contracts with their own US reporting quirks, and employer contributions may be currently taxable US income even though Spain defers them.

None of this means Americans should avoid Spanish retirement saving outright — the Spanish deduction and employer contributions can still beat the US friction. It means each vehicle needs a US analysis before you commit, and every existing account belongs on your FBAR and, usually, Form 8938 and Modelo 720.

Does Spain Tax US Social Security? The Treaty Answer

Yes. If you are a Spanish tax resident, Spain taxes your US Social Security in full as pension income at progressive IRPF rates, and the United States keeps taxing it too.

What Article 20 actually says

Article 20 of the 1990 US-Spain treaty, which the 2019 protocol did not amend, contains two different rules. Paragraph 1(a) says private pensions for past employment are taxable only in the country where you live. Paragraph 1(b) says Social Security paid by one country to a resident of the other may be taxed by the paying country. "May be taxed" is not "shall be taxable only". The US keeps its right to tax the benefit, and Spain keeps its right to tax you as a resident on worldwide income. Article 24 then makes Spain, as your country of residence, relieve the overlap by crediting the US tax.

IRS Publication 915 confirms the US side. It lists the treaty countries whose residents receive US Social Security free of US tax: Canada, Egypt, Germany, Ireland, Israel, Italy, Japan, Romania and the United Kingdom. Spain is not on the list. The saving clause would let the US tax its citizens anyway.

What you actually pay

• Spain: the benefit goes on your Renta as rendimiento del trabajo and is taxed on the general scale, roughly 19% to 47% depending on your region. There is no 85% cap and no exempt slice.
• United States: up to 85% of the benefit is taxable depending on your other income.
• The credits: you pay the US first, claim the US tax as a deduccion por doble imposicion on the Spanish return, then credit any remaining Spanish tax on Form 1116 in the general category. Your total bill lands close to the Spanish rate.
• Government pensions are different: federal, state and military pensions fall under the government service article and are taxable only by the US unless you are also a Spanish national.

The Beckham exception

Under the Beckham regime Spain taxes only Spanish-source income, so US Social Security escapes Spanish tax entirely for up to six years. Few retirees qualify, because the regime needs a Spanish employment contract or a qualifying entrepreneur or remote-employee role. Our separate Beckham law guide for US citizens covers who gets in.

Investing From Spain: PFICs, Wealth Tax, and the Solidarity Tax

The most expensive investing mistake an American in Spain can make is holding ordinary Spanish or EU funds. Nearly every fondo de inversion, SICAV, and EU-domiciled UCITS ETF sold by Spanish banks is a Passive Foreign Investment Company (PFIC) under US law. PFIC taxation is punitive — gains and certain distributions taxed at top ordinary rates plus an interest charge for deferral — and each fund needs its own Form 8621, easily hundreds of dollars per fund per year in compliance cost alone. The Spanish tax perk of rolling funds tax-deferred (traspaso) has no US equivalent and does not cure the PFIC problem.

Spain then adds two taxes on capital that the US system has no answer for:

Wealth tax (Impuesto sobre el Patrimonio)

Most communities levy an annual tax on net worth above a threshold — commonly EUR 700,000, plus a separate allowance (often around EUR 300,000) for your main home. Rates and reliefs vary enormously by region: Madrid, Andalusia and Extremadura grant a 100% rebate, Galicia 50%, while Catalonia, Valencia, and others charge it in full at progressive rates.

Solidarity Tax on Large Fortunes (Impuesto de Solidaridad de las Grandes Fortunas)

A state-level tax introduced to reach net wealth above roughly EUR 3 million — deliberately designed to capture residents of low-wealth-tax regions like Madrid. Passed as temporary for 2022 and 2023, it was made indefinite by Royal Decree-Law 8/2023 and still applies in 2026. Wealth tax paid is credited against it to avoid overlap.

Neither wealth tax nor the Solidarity Tax is a creditable US income tax — they are taxes on capital, so they do not reduce your US bill and cannot go on Form 1116. The practical playbook: hold US-domiciled ETFs through a US brokerage that accepts Spanish-resident clients, keep Spanish accounts for cash and daily banking, and factor wealth and Solidarity taxes into where in Spain you choose to live.

Wealth Tax and the Solidarity Tax: Regional Rules for Americans

Spain taxes you every year for owning things, and where you live inside Spain decides whether the bill is zero or six figures. Both taxes are assessed on your net worth at December 31, worldwide if you are resident, Spanish assets only if you are not.

What counts

Everything counts: your 401(k) and IRA at year-end value, US brokerage accounts, cash, crypto, the equity in your home and any rental property, net of mortgages. Spanish planes de pensiones are exempt, but Hacienda does not extend that exemption to US retirement plans. The state allowance is EUR 700,000 per person plus EUR 300,000 for your main home, so a couple shelters EUR 2 million before anything is due. Catalonia and Valencia cut the personal allowance to EUR 500,000. The Balearics raised theirs to EUR 3 million from 2024.

Where you live decides the rate

• Madrid, Andalusia and Extremadura: 100% bonification, so ordinary wealth tax is zero.
• Galicia: 50% bonification.
• Catalonia: 0.21% to 3.48% on net wealth above EUR 500,000.
• Valencia: 0.25% to 3.5% above EUR 500,000.
• Most other regions: the state scale of 0.2% to 3.5% above EUR 700,000.

The solidarity tax closes the Madrid loophole

The Impuesto de Solidaridad de las Grandes Fortunas is a state tax on net wealth above EUR 3 million, with the same EUR 700,000 allowance and EUR 300,000 home exemption. Rates are 1.7% from EUR 3 million to EUR 5.35 million, 2.1% to EUR 10.7 million and 3.5% above. Any regional wealth tax you paid is credited against it, so residents of Catalonia rarely pay extra while residents of Madrid pay in full. Passed as temporary for 2022 and 2023, it was made indefinite by Royal Decree-Law 8/2023 and applies in 2026.

Two limits and the US side

A joint cap stops IRPF plus wealth tax from exceeding 60% of your IRPF base. Wealth tax is filed on Modelo 714 with your Renta by June 30 if you owe tax or hold gross assets above EUR 2 million; the solidarity tax uses Modelo 718 in July. Neither tax is an income tax, so neither is creditable on Form 1116 nor deductible on Schedule A. The levers left are choice of region, a mortgage against Spanish property, and timing the move so your first December 31 as a resident falls after any planned drawdown or gift.

Modelo 720: Spain's Foreign-Asset Declaration and Your US Reports

Spain requires tax residents to file Modelo 720, an annual informational declaration of foreign assets, when holdings in any of three categories exceed EUR 50,000: (1) foreign bank and financial accounts; (2) foreign securities, investments, life insurance, and annuities; and (3) foreign real estate. It is filed by March 31 for the prior year, and once filed you only re-report a category if its value grows by more than EUR 20,000 or you close a position.

For Americans this is a US-style asset report — but to Spain, and it is entirely separate from your US obligations. You can easily owe all of the following in the same year: Modelo 720 to Hacienda, FBAR (FinCEN 114) to the US Treasury on foreign accounts over $10,000, and Form 8938 to the IRS on specified foreign assets over the resident-abroad thresholds ($200,000 year-end / $300,000 any time). The forms overlap in what they cover but none substitutes for another.

The penalty history matters

Spain originally paired Modelo 720 with famously draconian penalties — flat fines per data point and the treatment of undeclared assets as unjustified capital gains. On January 27, 2022, the Court of Justice of the European Union ruled that regime disproportionate and contrary to EU law, and Spain repealed the specific penalties. But the striking-down of the penalties did not end the obligation: the Modelo 720 filing requirement itself remains fully in force. Americans in Spain must still file it, on time, every year they are resident and over the threshold.

What replaced the old fines is the general penalty regime: EUR 20 per missing data item, minimum EUR 300 and maximum EUR 20,000, halved if you file late before Hacienda asks. Undeclared assets can still be assessed as unjustified gains, but only within the normal four-year statute of limitations.

Crypto goes on Modelo 721

Crypto held on a foreign exchange or with a foreign custodian no longer goes on Modelo 720. Since the 2023 tax year it goes on Modelo 721, also due March 31, once the total exceeds EUR 50,000 at year end, and again whenever the balance grows by more than EUR 20,000. Self-custodied wallets are not reported. Coinbase, Kraken and every other US exchange count as foreign custodians for a Spanish resident. On the US side the same coins are not yet FBAR-reportable under current FinCEN guidance, but Form 8938 may still apply.

Self-Employment in Spain: The Autonomo and Your US Return

Self-employed Americans in Spain register as autonomos with Hacienda and the social security system. Spain runs a contribution system for the self-employed that in recent years has moved toward brackets based on real net income, alongside quarterly IRPF prepayments (pagos fraccionados) and, usually, quarterly IVA (VAT) returns unless an exemption applies.

On the US side, your Spanish business income lands on Schedule C in US dollars, and two levers drive the outcome — but only one works in your favor in Spain.

First, income tax: Spanish IRPF on your profit is creditable, so with the Foreign Tax Credit most self-employed expats owe little or no US income tax on the business profit (outside the Beckham regime).

Second, self-employment tax: here Spain is unusually harsh. Because there is no US-Spain totalization agreement, there is no certificate of coverage to exempt you from the 15.3% US self-employment tax. You generally pay Spanish autonomo social security AND US SE tax on the same earnings — a genuine double social charge with no treaty relief. This changes the economics of freelancing from Spain versus a totalization country, and it should shape your structure from day one.

Watch entity choices. A Spanish sociedad limitada (SL) owned by a US person is a controlled foreign corporation, bringing Form 5471, GILTI, and Subpart F into play — get advice before incorporating, because for a one-person company the US compliance cost can dwarf the Spanish benefit.

Autonomos and the SL: Spanish Self-Employment and Companies on a US Return

Freelancing from Spain means two social security systems and two income taxes with no treaty bridge. Here are the numbers, and the one structure that removes the double social charge.

What an autonomo pays in 2026

Contributions are set by tramos of net income. The planned increase for 2026 was withdrawn, so the 2025 table carries forward:

• Net income up to EUR 670 a month: EUR 200 a month
• EUR 1,300 to EUR 1,700: EUR 294
• EUR 2,330 to EUR 2,760: EUR 415
• EUR 4,050 to EUR 6,000: EUR 530
• Above EUR 6,000: EUR 590

New autonomos pay the tarifa plana of EUR 80 a month for the first 12 months, extendable for another 12 if net income stays below the minimum wage. Net income here is profit less a further 7% generic deduction, regularised against your Renta the following year. You also file Modelo 130 quarterly, prepaying 20% of cumulative profit against IRPF, and Modelo 303 for IVA at 21%. Services billed to US clients are usually outside the scope of Spanish IVA, but you still file.

The US side of an autonomo

Profit goes on Schedule C in dollars. Spanish IRPF is creditable, so income tax is rarely the problem. Self-employment tax is the problem: 15.3% on 92.35% of profit, with no certificate of coverage because there is no totalization agreement, and the Spanish cuota is neither creditable nor an income tax. Beckham does not rescue you either: it is open to employees, ENISA-certified entrepreneurs and remote employees, not ordinary freelancers.

When an SL makes sense

A sociedad limitada pays Impuesto sobre Sociedades at 25%, 23% for companies under EUR 10 million of turnover in 2026, and 15% for a new company's first two profitable years. For an American owner the SL is a controlled foreign corporation: Form 5471 every year, and the net CFC tested income rules on undistributed profit. The high-tax exception switches those rules off when the Spanish effective rate exceeds 18.9%, which the 25% and 23% rates clear and the 15% start-up rate does not. The real prize is different: salary paid by a foreign company for work done outside the US carries no US self-employment tax, so routing your income through an SL as wages removes the 15.3% charge that an autonomo cannot escape. Weigh it against accounting fees and the 5471 first.

Buying, Owning, and Selling Spanish Property

Spain is a property magnet for Americans, and the tax mechanics differ sharply from the US. On purchase you pay transfer tax (ITP) on resale homes or IVA plus stamp duty (AJD) on new-builds, at regionally varying rates. While you own, non-let second homes attract an imputed income charge (renta imputada) on the cadastral value, and let property is taxed on the rent; the property also enters your wealth-tax base.

On sale, Spain taxes a resident's gain as savings income (19%-30%), a non-resident pays a flat 19% after the buyer withholds 3% of the price on Modelo 211, and the municipality may levy plusvalia municipal on the land-value increase (zero if you can show no real gain, since the 2021 reform). The United States does not care about Spanish reliefs: as a US citizen you owe US capital gains tax on the sale regardless of Spanish treatment, with only the $250,000/$500,000 primary-residence exclusion (if you qualify) to offset it. Where both countries tax the gain, the Foreign Tax Credit bridges most of it; where Spain grants relief (for example, reinvestment relief on a main home for those over 65), there may be little Spanish tax to credit and a real US bill.

Two US quirks catch sellers everywhere. Gain is computed in US dollars, so exchange-rate movement between purchase and sale can create a taxable dollar gain on a flat euro price, or vice versa. And paying off a euro mortgage can itself produce taxable phantom exchange-rate gain under Section 988 if the dollar strengthened between borrowing and repayment. Rental property adds dual reporting — Spanish tax on the rent (residents pay progressive IRPF after a 50% reduction on long-term residential lets signed since May 26, 2023, or 60% on older contracts; non-resident Americans pay a flat 24% on gross rent with no deductions on Modelo 210), plus US Schedule E with 30-year straight-line depreciation for foreign residential property placed in service after 2017. Keep euro records of every improvement from day one.

Behind on US Taxes? The Streamlined Path Back, and Deadlines

Many of our Spanish clients come to us years behind on US filings — often after a Spanish bank asked for a W-9 under FATCA, or after reading about FBAR penalties. If that is you, do not panic, and do not quietly file several years of back returns ('quiet disclosure' forfeits penalty protection).

The IRS Streamlined Foreign Offshore Procedures exist for non-willful non-filers abroad: three years of returns, six years of FBARs, and a certification of non-willful conduct, with all late-filing, late-payment, and FBAR penalties waived. Most streamlined filers from Spain owe little or no back tax once the Foreign Tax Credit is applied, and many collect refunds through the refundable Additional Child Tax Credit. The program has no announced end date, but it is only available before the IRS contacts you first, and Spanish banks report US-person accounts under the FATCA intergovernmental agreement.

Your two-country calendar

• April 15: US tax payment deadline — interest starts here even though expats get an automatic filing extension.
• June 15: automatic two-month filing extension for Americans abroad.
• October 15: extended US deadline with Form 4868; FBAR is due April 15 but auto-extends to October 15.
• March 31: Spanish Modelo 720 foreign-asset declaration for the prior year.
• April to June 30: Spanish IRPF (Renta) filing window for the prior year.
