Tax Treaty

Since 1990

Local Tax Rate

Combined state + autonomous-community IRPF, progressive to roughly 45%-54% at the top depending on region; savings income (interest, dividends, gains) 19%-28%; plus wealth tax and the Solidarity Tax on large fortunes

Filing Deadline

US: April 15 (payment), June 15 (automatic expat extension), October 15 (with Form 4868; FBAR too). Spain: Modelo 720 by March 31; IRPF (Renta) filed April to June 30.

US-Spain Tax Relationship

The US-Spain income tax treaty (signed 1990, in force 1990) allocates taxing rights between the two countries and prevents most double taxation. A major 2013 Protocol entered into force on November 27, 2019, cutting withholding on many dividends toward the 15% portfolio cap and reducing interest and most royalties to 0% at source. Employment income is generally taxed where the work is performed, and pensions and government service have their own rules. Critically, the treaty's saving clause lets the United States tax its own citizens as if the treaty did not exist (with narrow, listed exceptions), so for most Americans the treaty orders the two systems — determining which country taxes first so the other grants a credit — rather than reducing the IRS bill directly. For an ordinary Spanish resident, combined state-plus-regional IRPF rates usually exceed US rates, so the Foreign Tax Credit eliminates US tax and builds a carryforward; under the Beckham regime, low Spanish tax can leave real US tax owed. Two limits matter in Spain: the treaty is an income tax treaty and does not relieve Spanish wealth tax or the Solidarity Tax, and there is no US-Spain totalization agreement, so it does nothing for social security or self-employment tax. Certain treaty positions must be disclosed on Form 8833.

Key Tax Considerations for Spain

The Beckham Law can raise your US tax, not lower it

The Beckham regime taxes qualifying arrivals at a flat 24% on Spanish employment income and generally exempts foreign income for up to six years. For a US citizen that is a trap as often as a benefit: paying less Spanish tax leaves less Foreign Tax Credit, so you can owe more to the IRS than an ordinary Spanish resident would. It can also weaken your treaty-residence position. We model the combined US-plus-Spanish outcome both ways before you elect, so the decision is made with the full picture rather than the Spanish half of it.

Modelo 720 is still mandatory — separate from FBAR

Spanish residents must file Modelo 720 declaring foreign assets over EUR 50,000 in any category, due March 31. The EU Court of Justice struck down Spain's draconian penalties in January 2022, but the filing obligation itself remains fully in force. It does not replace your US FBAR or Form 8938 — you can owe all three in the same year on overlapping assets. We prepare your US reports and make sure your Modelo 720 data lines up with them.

No US-Spain totalization agreement

Unlike Germany, France, the UK, and Italy, Spain has no totalization agreement with the US. For self-employed Americans this is costly: there is no certificate of coverage, so an autonomo generally pays both Spanish social security and the 15.3% US self-employment tax on the same earnings. Spanish social contributions are not creditable on Form 1116. This is frequently the single largest US cost of living in Spain, and it shapes how we structure self-employed and small-company clients.

FEIE vs Foreign Tax Credit turns on Beckham

For an ordinary Spanish resident, the Foreign Tax Credit usually wins — combined IRPF rates exceed US rates, wiping out US tax and building a ten-year carryforward while preserving the refundable Additional Child Tax Credit. Under Beckham, low flat Spanish tax can leave real US liability, so the FEIE (up to $132,900 for 2026) and housing exclusion often do more work. We model both methods and pick the mix that minimizes your combined bill.

PFIC trap in Spanish and EU funds

Nearly every Spanish fondo de inversion, SICAV, and EU UCITS ETF is a Passive Foreign Investment Company under US law. PFIC taxation is punitive — top ordinary rates plus an interest charge — and each fund needs its own Form 8621. Spain's tax-deferred fund-switching (traspaso) does not cure it. We identify PFIC exposure, prepare Form 8621, and help you restructure toward US-domiciled ETFs held at a US brokerage that accepts Spanish residents.

Wealth tax and the Solidarity Tax

Most communities levy an annual wealth tax on net worth above a threshold, and the state Solidarity Tax reaches fortunes above roughly EUR 3 million — deliberately targeting residents of low-wealth-tax regions like Madrid. Both are taxes on capital, not income, so neither is creditable on Form 1116. They do not reduce your US bill, and the region you choose to live in can change them dramatically. We factor them into your overall US-plus-Spanish position.

Spanish pensions and planes de pensiones

Spanish private pension plans are deductible locally but generally not qualified for US purposes — growth may be currently taxable, contributions are not US-deductible, and the plans usually hold PFIC funds. Depending on structure, foreign-trust reporting on Forms 3520/3520-A can apply. We analyze each account, report it correctly on your US return, FBAR, and Form 8938, and coordinate with your Spanish advisor on future contributions.

FBAR & FATCA on Spanish accounts

All Spanish financial accounts — cuentas corrientes, savings, brokerage, and pension accounts — count toward the $10,000 FBAR threshold. Spain reports US-person accounts under its FATCA intergovernmental agreement, so Spanish banks will ask you for a W-9. Form 8938 thresholds for residents abroad are $200,000 (year-end) / $300,000 (any time). We prepare FBAR and Form 8938 alongside your return and reconcile them with your Modelo 720.

Move-year and residency timing

Spain generally treats you as resident for the whole calendar year once you cross 183 days, with no split-year relief, and the Beckham election must be made within a set window after starting work. Your year of arrival is the most error-prone return you will file from Spain. We handle the allocation, confirm your residency posture, and time the elections — Beckham, FEIE, FTC — to minimize the combined US-plus-Spanish bill.

Required US Tax Forms

Form 1040

US Individual Tax Return

Required for all US citizens and green card holders regardless of residence. Reports worldwide income — Spanish salary, self-employment, investment, and rental income — converted to USD.

Form 1116

Foreign Tax Credit

Claims dollar-for-dollar credit for Spanish IRPF (state and autonomous-community portions). For ordinary residents this usually generates excess credit that carries forward ten years; under Beckham the creditable pool is much smaller.

Threshold: Dollar-for-dollar credit up to US tax on foreign income

Form 2555

Foreign Earned Income Exclusion

Excludes up to $132,900 of foreign earned income for 2026. Often the primary tool under the Beckham regime, where low Spanish tax limits the Foreign Tax Credit.

Threshold: Up to $132,900

FBAR (FinCEN 114)

Foreign Bank Account Report

Reports all Spanish financial accounts — checking, savings, brokerage, and pension accounts. Non-willful penalties can exceed $16,000 per account per year.

Threshold: $10,000 aggregate at any point during the year

Form 8938

FATCA Statement of Foreign Financial Assets

Reports specified Spanish financial assets with your Form 1040. Separate from Spain's own Modelo 720 asset declaration.

Threshold: $200,000 (year-end) / $300,000 (any time) for residents abroad

Form 8621

PFIC Annual Information Return

Required for each Spanish or EU fund, SICAV, or ETF held — nearly all are PFICs. Each fund needs a separate form; default Section 1291 treatment is punitive.

Threshold: Any ownership in a Spanish/EU investment fund

Form 8833

Treaty-Based Return Position Disclosure

Required when relying on the US-Spain treaty to modify US tax — including certain pension and residency positions.

Threshold: Any treaty-based position that affects US tax

Form 3520 / 3520-A

Foreign Trust Reporting

May apply to certain Spanish planes de pensiones and pension or insurance structures depending on how they are classified.

Threshold: Ownership of or transactions with a foreign trust

Common Expat Scenarios

Tech worker on the Beckham regime in Madrid (EUR 140,000 salary)

US citizen relocated to a Madrid tech company, elected the Beckham Law, taxed at a flat 24% on Spanish salary with US investment income untaxed by Spain.

Our Approach: Because Beckham keeps Spanish tax low, the Foreign Tax Credit alone will not cover the US bill. We apply the FEIE and housing exclusion to the first tranche of salary, credit the flat 24% Spanish tax against the remainder, and plan around the US-taxed but Spain-exempt investment income. We compare the projected combined bill with and without Beckham so the client sees the full US cost of the election.

American freelancer (autonomo) in Barcelona

Self-employed designer billing EUR 90,000/year from Spanish and EU clients, registered as an autonomo, filing quarterly Spanish IVA and IRPF prepayments.

Our Approach: Spanish IRPF on the profit is creditable via Form 1116, reducing US income tax toward zero. But with no US-Spain totalization agreement, the client owes both Spanish social security and the 15.3% US self-employment tax — we build that double charge into the plan, evaluate whether a US or Spanish entity helps, and keep the Schedule C and IVA stories consistent.

Retiree on the Costa del Sol drawing US pensions

Retired American in Malaga receiving US Social Security and a US 401(k) distribution, holding a Spanish bank account and a small Spanish investment fund, with net worth near the wealth-tax threshold.

Our Approach: We report US Social Security and the 401(k) on Form 1040 with FTC for Spanish IRPF, flag the Spanish fund as a PFIC and plan a switch to US-domiciled holdings, and confirm FBAR, Form 8938, and Modelo 720 coverage. We review the wealth-tax and Solidarity-Tax exposure by community and coordinate with the Spanish asesor on the Renta.

Dual citizen behind on filings after a FATCA letter

US-born, long resident in Valencia, never filed US returns; received a W-9 request from a Spanish bank and panicked.

Our Approach: Enter the IRS Streamlined Foreign Offshore Procedures: three years of returns, six years of FBARs, and a non-willful certification, with all penalties waived. With the FTC, back-tax owed is usually zero, and refundable child credits may produce refunds. We prepare the entire package, the Form 14653 certification, and reconcile with any Spanish Modelo 720 history.

Remote worker family in Valencia with Spanish and US investments

American couple on Spain's digital-nomad visa, one spouse employed remotely by a US company, holding a Spanish brokerage with EU ETFs and a US brokerage back home, two children.

Our Approach: We determine residency and whether Beckham applies to the remote arrangement, credit Spanish IRPF via Form 1116 on the couple's Spanish-taxed income, and preserve the refundable Additional Child Tax Credit for the children. The EU ETFs are PFICs needing Form 8621; we plan a move to US-domiciled funds and file FBAR, Form 8938, and align them with Modelo 720.

Tax Advantages

US-Spain treaty (1990, modernized by the 2013 Protocol in force 2019) provides a framework against double taxation
For ordinary residents, high Spanish IRPF generates excess Foreign Tax Credit that carries forward ten years
We model the Beckham election both ways so you see its true US cost before committing
Streamlined Filing lets non-willful non-filers catch up penalty-free — often with zero back tax after the FTC
Refundable Additional Child Tax Credit remains available when using the FTC rather than the FEIE
We reconcile US FBAR and Form 8938 with Spain's Modelo 720 so the two systems stay consistent

Watch Out For

The Beckham regime lowers Spanish tax but can raise the US bill by shrinking the Foreign Tax Credit
Modelo 720 foreign-asset reporting is still mandatory despite the 2022 EU court ruling, on top of FBAR and Form 8938
No US-Spain totalization agreement, so self-employed Americans pay both Spanish social security and 15.3% US SE tax
Spanish and EU funds, SICAVs, and ETFs are PFICs requiring Form 8621 at significant annual cost
Wealth tax and the Solidarity Tax are non-creditable capital taxes that vary sharply by autonomous community
Combined state-plus-regional IRPF rates differ by region, complicating FTC modeling and where to live
Whole-year residency once past 183 days, with no split-year relief, makes move-year returns error-prone

Frequently Asked Questions

Do I still have to file US taxes while living in Spain?

Yes. US citizens and green card holders file Form 1040 every year on worldwide income no matter where they live. Filing rarely means paying for an ordinary Spanish resident — high Spanish IRPF rates usually zero out the US bill through the Foreign Tax Credit or the Foreign Earned Income Exclusion (up to $132,900 for 2026). The exception is the Beckham regime, where low Spanish tax can leave real US tax owed. Either way, the paperwork — including FBAR and Form 8938 — is mandatory, and the penalties for skipping information forms are far harsher than anything tied to the tax.

Is the Beckham Law a good idea for an American?

Often not, once you factor in US tax. The regime taxes Spanish employment income at a flat 24% and exempts most foreign income, which is a clear win for non-Americans. But because the US taxes your worldwide income, paying less Spanish tax leaves less Foreign Tax Credit — so a Beckham-regime American can owe more to the IRS than an ordinary Spanish resident would. It can also complicate your treaty-residence status. We always model the combined US-plus-Spanish outcome both ways before a client elects Beckham.

What is Modelo 720 and do I still have to file it?

Modelo 720 is Spain's annual declaration of foreign assets over EUR 50,000, due March 31. In January 2022 the EU Court of Justice struck down Spain's disproportionate penalties, but the filing obligation itself remains fully in force — only the punitive fines were removed. It is separate from your US FBAR and Form 8938, so you can owe all three in the same year on overlapping assets. We prepare your US reports and make sure the figures reconcile with your Modelo 720.

Why is there no relief for Spanish wealth tax on my US return?

The US Foreign Tax Credit only relieves foreign income taxes. Spain's wealth tax (Impuesto sobre el Patrimonio) and the Solidarity Tax on Large Fortunes are taxes on your net capital, not your income, so they cannot go on Form 1116 and do not reduce your US bill. They are a cost of residing in a community that levies them — which is why the region you live in matters so much, with Madrid historically granting near-total relief and Catalonia and Valencia charging in full.

I'm self-employed in Spain — do I owe US self-employment tax too?

Usually yes, and this is where 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. An American autonomo generally pays both Spanish social security and US SE tax on the same earnings. Spanish social contributions are not creditable on Form 1116. For self-employed clients this missing agreement is often the largest single US cost of living in Spain, so we plan for it from the outset.

Are my Spanish index funds and ETFs a US tax problem?

Almost always. Spanish fondos de inversion, SICAVs, and EU-domiciled UCITS ETFs are Passive Foreign Investment Companies (PFICs) under US law. PFIC income is taxed at top ordinary rates plus an interest charge, and each fund needs its own Form 8621. Spain's tax-deferred fund-switching (traspaso) is a Spanish perk that does not cure the US treatment. The fix is usually to hold US-domiciled ETFs through a US brokerage that accepts Spanish residents and keep Spanish accounts for cash.

Should I use the FEIE or the Foreign Tax Credit in Spain?

It depends on whether you are on the Beckham regime. For an ordinary Spanish resident, the Foreign Tax Credit usually wins — combined state-plus-regional IRPF rates exceed US rates, wiping out US tax and leaving a ten-year carryforward, while preserving the refundable Additional Child Tax Credit that the FEIE forfeits. Under Beckham, low flat Spanish tax limits the credit, so the FEIE and housing exclusion often do more of the work. We model both before filing your first Spanish-year return.

I haven't filed US taxes in years. What now?

Use the IRS Streamlined Foreign Offshore Procedures, designed for non-willful non-filers abroad: three years of returns, six years of FBARs, and a non-willful certification, 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 some collect refunds. Don't file back returns cold ('quiet disclosure') — it forfeits penalty protection. The program is only available before the IRS contacts you first, and Spanish banks already report US accounts under FATCA.

Do you coordinate with my Spanish asesor or gestor?

Yes. Because the Spanish tax you pay drives your US Foreign Tax Credit, and because the Beckham election and Modelo 720 interact with your US reporting, the two sides need to tell one consistent story. We work directly with your Spanish asesor on timing, figures, and treaty positions, and sequence the filings so the Spanish return informs the US one. If you don't have a Spanish advisor yet, we can point you to the local side.
