🇺🇸 COUNTRY A USA VS 🇪🇸 COUNTRY B Spain

Yes, US citizens must file US taxes regardless of where they live. However, the Foreign Earned Income Exclusion (FEIE) excludes the first $130,000 (2026) of foreign-earned income. Income above that may be subject to both systems, but foreign tax credits prevent double taxation. You pay Spanish taxes on all income earned in Spain, then claim credits on your US return.

The Beckham Law (Impatriado regime) offers qualifying expats a 24% flat tax rate on Spanish-sourced income up to €600,000 for the first 5 years (vs standard progressive rates up to 47%). You qualify if: (1) you haven't been a Spanish tax resident in the past 5 years, (2) you move to Spain for work, and (3) you apply within 6 months of starting work. Saves $18,000+/year at $150K income.

The FEIE allows US citizens living abroad to exclude $130,000 (2026) of foreign-earned income from US taxes. You must meet either the Physical Presence Test (330 days outside US in 12 months) or Bona Fide Residence Test (full-year Spanish tax resident). Income above $130,000 is taxable in the US, but you can claim foreign tax credits for Spanish taxes paid to avoid double taxation.

Spain offers universal public healthcare free or low-cost to residents (funded through taxes and social security contributions). US requires private insurance averaging $500-1,500/month for individuals ($6,000-18,000/year) plus deductibles. Even with higher Spanish tax rates, the healthcare savings alone can offset $6,000-18,000 annually.

Madrid is approximately 40% cheaper than New York City overall. Rent: 1-bed apartment $1,200 Madrid vs $3,500 NYC. Groceries: 30% cheaper. Dining out: 40% cheaper. Public transit: $60/month Madrid vs $132 NYC. Barcelona costs are similar to Madrid. Spain's lower cost of living can offset higher tax rates for many earners.

Yes, Spain launched a Digital Nomad Visa in 2023 for remote workers earning income from outside Spain. Requirements: earn at least €2,334/month, work for non-Spanish companies, have valid health insurance. The visa allows 12 months (renewable up to 5 years). You become a Spanish tax resident after 183 days, subject to Spanish income tax on worldwide income, but may qualify for Beckham Law's 24% flat rate.

Spain's total contributions are much higher: employees pay 6.35% + employers pay 29.9% (36.25% total). US Social Security is 6.2% employee + 6.2% employer (12.4% total) capped at $176,100 in 2025, plus 1.45% Medicare each (2.9% total uncapped). However, Spain's contributions fund comprehensive universal healthcare, unemployment insurance, and pension.

Yes, US citizens must file a US tax return annually regardless of where they live, reporting worldwide income. Even if you owe no US tax due to FEIE ($130,000 exclusion) or foreign tax credits, you must still file Form 1040, Form 2555 (FEIE), and potentially FBAR (foreign bank accounts over $10,000) and FATCA Form 8938 (foreign assets). Many expats use specialized tax services like Greenback to ensure compliance.

Foreign Tax Credit (Form 1116) allows you to offset US tax liability dollar-for-dollar with foreign taxes paid to Spain. If you earn $150,000 in Spain and pay $54,200 Spanish tax, you can claim that against your US tax liability. Since Spanish rates (up to 47%) are often higher than US rates, high earners typically owe no additional US tax after credits, but must still file.

Generally no—you need US-sourced earned income to contribute to 401(k)s or IRAs. If you work for a US company remotely from Spain, you may qualify. Spain has its own pension system funded through social security contributions. US expats should consult a cross-border tax advisor, as Spanish tax treatment of US retirement accounts can be complex (some US accounts are taxed as regular income in Spain).

Spain offers: free public healthcare for children, 16 weeks paid maternity leave (vs US average 12 weeks unpaid), subsidized childcare, excellent public schools, safer cities (lower crime rates), 30 days vacation to spend with family. US offers: higher salaries, more spacious housing, better career advancement, English-language environment. Spain wins for work-life balance and child-rearing costs; US wins for earning potential.
