U.S. Remote Workers Moving to Spain: Your Complete Tax Picture

Two systems, one move

The most important concept to understand before anything else: the U.S. and Spain both have a claim on your income when you live in Spain as a U.S. citizen or permanent resident.  Spain taxes you as a resident on your worldwide income (or, if you elect the Beckham regime, on your Spanish-source income at a flat rate).  The U.S. taxes you on your worldwide income regardless of where you live.  The U.S.–Spain tax treaty and bilateral provisions like the Foreign Tax Credit exist to prevent the same dollar from being taxed twice, but they require deliberate elections and filings to work correctly.  They do not happen automatically.

The interaction between these two systems is the reason a visa lawyer and a tax advisor are different professionals.  The immigration side is what this practice handles.  The tax side requires someone who understands both U.S. and Spanish tax law, and those two bodies of law are not the same discipline.  What follows is a map of the terrain, not a substitute for professional tax advice specific to your situation.

Becoming a Spanish tax resident

Spain’s primary test for tax residency is the 183-day rule: if you spend more than 183 days in Spain in a calendar year, you are a Spanish tax resident for that year and must file a Spanish income tax return (Modelo 100, also known as the Renta).  Spain also has secondary tests (center of vital interests, or having a spouse and underage children resident in Spain) that can establish residency even before the 183 days are up.

A few things the Digital Nomad Visa does not do: it does not automatically make you a tax resident, and it does not exempt you from Spanish taxes.  The visa is an immigration permission; the tax consequences follow from where you actually spend your time.  Most DNV holders become Spanish tax residents within their first or second full calendar year in Spain, simply because they are living there.

The year you arrive matters for a different reason: your first Spanish tax year may be a split year, with partial obligations in both countries.  This is precisely where early coordination with a tax professional pays for itself most clearly.

The Beckham option: 24% flat rate for six years

Spain’s expatriate tax regime, known informally as the Beckham Law, allows qualifying individuals to be taxed as non-residents in Spain for up to six tax years.  The practical effect: a flat 24% tax rate on Spanish-source income up to €600,000, rather than the progressive IRPF scale that starts at 19% and reaches 47% at the top.  Foreign-source income is generally exempt from Spanish taxation during the regime.

For most U.S. remote workers on a DNV, the Beckham regime is highly advantageous, particularly for W‑2 employees of U.S. companies whose entire paycheck qualifies as foreign-source income.  The 2022 reform of the regime (through Ley 28/2022, the same law that created the Digital Nomad Visa) explicitly added remote workers to the list of qualifying categories.  An in-depth analysis of who qualifies and how it interacts with U.S. obligations is in the Beckham Law for U.S. Remote Workers guide.  Use the Beckham calculator to model your specific numbers.

Your U.S. tax obligations do not disappear

The United States taxes its citizens and permanent residents on worldwide income regardless of where they live.  This is not the norm globally (most countries tax based on residency, not citizenship) but it is U.S. law, and it applies to you whether you are in Madrid or Málaga or Milwaukee.

What this means in practice: you will continue filing a U.S. federal tax return every year.  You may owe U.S. tax, or you may not, depending on how your income is structured, which elections you make, and how the U.S.–Spain treaty applies to your situation.  But the filing obligation exists regardless of whether you owe anything.

The two main mechanisms for reducing or eliminating U.S. tax on foreign-earned income are the Foreign Earned Income Exclusion and the Foreign Tax Credit.  Both have significant nuances when combined with Spain’s Beckham regime.

FEIE vs.  Foreign Tax Credit: the choice that defines year one

These are the two primary U.S. tax tools available to Americans living abroad.  They work differently, and the choice between them (or the combination of them) has consequences that can compound over years.

The choice between FEIE and FTC is not reversible for six years once made.  This is one of the most consequential tax elections a U.S. expat can make, and it requires analysis by a professional who understands both U.S. federal tax and Spain’s Beckham regime.  The detailed interaction is covered in Beckham Law + U.S. Taxes: the Complete Guide.

FBAR, FATCA, and Modelo 720: the reporting obligations people miss

The U.S. and Spain both require separate asset-reporting filings that are not income tax returns.  They carry no tax liability themselves, but failing to file carries severe penalties.

FBAR — FinCEN Form 114

FBAR is required from any U.S. person who holds foreign financial accounts with an aggregate value exceeding $10,000 at any point during the year.  If you open a Spanish bank account (which you will need to do shortly after arriving), you will almost certainly exceed this threshold.  The FBAR is filed annually, due April 15 with an automatic extension to October 15.  It is separate from your tax return and filed directly with FinCEN, not the IRS.

FATCA — Form 8938

FATCA requires additional reporting on foreign financial assets above higher thresholds ($200,000 at year-end or $300,000 at any point during the year, for single filers living abroad).  Filed with your Form 1040.  Overlaps with FBAR in some respects but covers a broader category of assets including foreign investment accounts and insurance products.

Modelo 720 — Spain’s overseas asset declaration

Once you become a Spanish tax resident, Spain requires you to declare foreign accounts, securities, and real estate that individually exceed €50,000.  This is the Modelo 720, filed annually in the first quarter of the following year.  As a U.S. citizen moving to Spain with U.S. bank accounts, brokerage accounts, and potentially real estate, this filing becomes relevant from your first full year of Spanish tax residency.  The European Court of Justice ruled in 2022 that Spain’s original penalty regime was disproportionate; Spain revised the penalties in 2023, but the filing obligation itself remains.

Social Security: one system, not two

The U.S.–Spain Totalization Agreement prevents double contributions to Social Security.  You pay into one system, not both.  The rules differ depending on how you work:

• W‑2 employee of a U.S. company: Your employer obtains a Certificate of Coverage (SSA-24) from the Social Security Administration, which allows you and your employer to continue contributing to U.S. Social Security for up to five years while you work from Spain.  You do not register in Spain’s RETA during this period.  After five years, Spanish Social Security (TGSS or RETA) generally applies.
• Autónomo with foreign clients: If you have no U.S. employer paying into U.S. Social Security on your behalf, you will typically register in Spain’s RETA (Régimen Especial de Trabajadores Autónomos).  Monthly RETA contributions in 2026 are income-linked, from about €200/month for the lowest incomes to €590/month at the top of the table.

The Certificate of Coverage path is one of the most administratively important steps for W‑2 employees.  It prevents Spain from requiring RETA registration and keeps U.S. Social Security credits accruing.  Your employer’s payroll or HR team handles this, but they need to know it exists and be prompted to apply for it.

Business structures: S-Corp, LLC, and autónomo

How you are structured on the U.S. side before you move materially affects your Spanish tax and Social Security treatment.  The three most common situations for DNV applicants:

• W‑2 employee: Simplest case.  Employer letter, Certificate of Coverage, Beckham election.  The visa application and tax setup are relatively straightforward.
• Single-member LLC: A single-member LLC is a pass-through entity, U.S. tax sees its income as your personal income (Schedule C or Schedule E).  Spain’s treatment depends on whether Spain respects the LLC as a separate entity or looks through it.  This is a common source of complexity requiring specialist analysis.
• S-Corp owner: S-Corp distributions and salary have different treatment for both U.S. and Spanish tax purposes.  The S-Corp and C-Corp guide covers the immigration documentation side; the tax structuring requires a professional who works specifically with U.S. business owners relocating abroad.

A Spanish alternative worth knowing: once you are established in Spain, the autónomo vs.  Sociedad Limitada question becomes relevant.  An SL (the Spanish equivalent of an LLC) can be more tax-efficient above certain income levels, but it requires a Spanish accountant, annual accounts, and corporate tax filings.  It is not a simple setup.

Equity, RSUs, and crypto

These come up frequently because they affect both visa income qualification and ongoing Spanish tax treatment:

• RSUs and stock options: How RSUs are taxed under Beckham Law differs from standard IRPF treatment.  The RSUs and stock options tax guide covers the mechanics.  For visa qualification purposes, see whether RSUs count as qualifying income.
• Crypto: Spain taxes cryptocurrency gains and requires them to be declared in Modelo 721 (Spain’s crypto-specific asset declaration, introduced in 2024) and Modelo 100.  The crypto income guide covers qualification for the visa; crypto tax treatment in Spain is a specialist area.

Your first-year tax timeline

The first calendar year in Spain contains more tax decisions than any subsequent year.  The complete tax calendar maps every deadline.  The critical sequence:

What we handle — and what requires a tax specialist

This practice handles the immigration piece: the Digital Nomad Visa application, document preparation, UGE submission, and the residency card (TIE) process after approval.  That is our scope, and we handle it well.

The tax side (Beckham election, FEIE/FTC choice, FBAR and FATCA compliance, Modelo 720, RETA registration, U.S.-Spain treaty analysis) requires a different professional.  Specifically, it requires someone who understands both sides of the Atlantic simultaneously, because a decision made on the U.S. side affects the Spanish side and vice versa.
