Americans in Spain: A Comprehensive Journey from Residency to Filing
Moving to Spain as an American opens doors to a vibrant international community, excellent infrastructure, and the unique Spanish approach to work-life balance. However, it also means navigating the complexities of dual tax obligations. You'll need to satisfy both the Spanish Agencia Tributaria (tax authority) and the U.S. Internal Revenue Service (IRS). While this dual obligation can seem overwhelming, understanding the system is the first step to managing it effectively.
This comprehensive guide will walk you through every aspect of the tax landscape for U.S. expats in Spain, from determining your tax residency status to leveraging the U.S.-Spain tax treaty. Consider this your complete manual for achieving tax compliance while enjoying your Spanish experience. All figures and rules are updated for 2025 where applicable.
Part 1: Defining Your Status - Spanish Tax Residency for U.S. Expats
Your Spanish tax obligations depend fundamentally on whether you're considered a tax resident. Spanish residents are taxed on their worldwide income, while non-residents are only taxed on Spanish-source income.
You are generally classified as a Spanish tax resident if:
Primary Factors:
- Physical Presence: Spending more than 183 days in Spain during the calendar year (days are counted even if not consecutive).
- Permanent Home: Maintaining a home in Spain that's continuously available to you.
- Center of Life: Where your personal and economic interests are concentrated, including:
- Location of family or spouse
- Professional activities
- Bank accounts and investments
- Social connections and memberships
- Presumption for Family: If your spouse and minor children reside in Spain, you're presumed a resident unless proven otherwise.
The Treaty Tie-Breaker Rules
When you could be considered a resident of both the U.S. and Spain, the U.S.-Spain Tax Treaty provides tie-breaker rules:
- Permanent Home: Where do you have a permanent home available?
- Center of Vital Interests: If you have homes in both countries, where are your personal and economic relations closer?
- Habitual Abode: Where do you spend more time?
- Nationality: Your citizenship becomes the deciding factor.
Understanding these rules is crucial for determining where you'll pay taxes on your worldwide income.
Part 2: Deconstructing the Spanish Tax System
Spain uses a progressive tax system for personal income (IRPF - Impuesto sobre la Renta de las Personas Físicas), separating income into general base (employment, business, real estate) and savings base (investments, capital gains).
General Income Base
This includes:
- Employment income (wages, bonuses, benefits)
- Self-employment and business income
- Rental income
- Pensions and annuities
- Alimony received

Part 3: Your U.S. Tax Obligations While Living Abroad
Your U.S. citizenship means you must file U.S. tax returns annually, reporting worldwide income. The key is using available tools to prevent double taxation.
The Core Tools: FEIE vs. FTC
1. Foreign Earned Income Exclusion (FEIE):
- Exclude up to $130,000 (2025) of foreign-earned income.
- Applies to wages and self-employment income, not passive income.
- Must meet either Physical Presence Test (330 days abroad) or Bona Fide Residence Test.
2. Foreign Tax Credit (FTC):
- Dollar-for-dollar credit for Spanish taxes paid.
- Often more beneficial than FEIE due to high Spanish tax rates.
- Can carry excess credits forward or back.
- Separates income into categories (general, passive, etc.).
Which to choose?
- FEIE: Better if income is under the threshold and Spanish taxes are low.
- FTC: Usually optimal for Spain residents due to high tax rates.
- You can use both, but not on the same income.
Housing Cost Exclusion/Deduction
If using FEIE, you may also exclude/deduct qualified housing costs exceeding a base amount:
- Rent, utilities (except phone/TV/internet)
- Real and personal property insurance
- Residential parking
- Base amount for 2025: $20,800
Reporting Requirements: FBAR & FATCA
FBAR (FinCEN Form 114):
- Required if foreign accounts exceed $10,000 aggregate at any point.
- Includes Spanish bank accounts, investment accounts, pension funds.
- Filed separately from tax return by April 15 (automatic extension to October 15).
FATCA (Form 8938):
- Higher thresholds than FBAR.
- Single filers abroad: $200,000 year-end or $300,000 any time.
- Married filing jointly abroad: $400,000 year-end or $600,000 any time.
Penalties for non-compliance are severe, non-willful FBAR penalties up to ~$16,000 per violation (inflation-adjusted for 2025); willful up to the greater of $161,000 or 50% of account balance. FATCA starts at $10,000.
State Tax Considerations
Many states continue claiming tax rights over expats:
- Aggressive states: California, Virginia, New Mexico, South Carolina
- Tax-friendly states (no income tax): Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming
Consider establishing residency in a tax-friendly state before moving abroad.
Part 4: The U.S.-Spain Tax Treaty
The treaty prevents double taxation and provides important benefits:
Key Treaty Provisions
- Savings Clause: The U.S. retains the right to tax its citizens as if the treaty didn't exist, but specific exceptions apply.

- Private pensions: Generally taxable in country of residence.
