The Growing Exodus of High-Net-Worth Americans
Official 2026 data shows that over 142,000 high-net-worth individuals relocated internationally in 2025, with many Americans choosing European destinations for their lifestyle, healthcare, and favourable tax structures. The United States, though, remains one of only two countries globally that taxes based on citizenship rather than residency, which creates real headaches for American expats managing retirement wealth abroad.
For Americans living in Europe, the problem goes beyond basic tax compliance. Your 401(k), IRA, and Roth IRA accounts face ongoing reporting requirements, potential broker restrictions, and the need to work across two tax systems at once. When you’re managing substantial assets across jurisdictions, how you structure your financial affairs matters enormously.
European Tax Advantages vs US Citizenship-Based Taxation
Portugal’s tax landscape shifted significantly when its Non-Habitual Resident scheme ended in early 2025. Foreign income remains generally untaxed for new residents, though, whilst local Portuguese income faces a flat 20% rate. For Americans with properly structured offshore investments and pension arrangements, that’s still worth paying attention to.
Italy’s flat tax regime offers another compelling option, capping global tax liability at €200,000 per year for qualifying residents. For high-net-worth Americans with substantial retirement assets, that ceiling can mean significant savings compared to US progressive tax rates on worldwide income.
Spain’s Non-Lucrative Visa requires proof of passive income around €2,400 monthly, making it accessible for Americans with steady retirement distributions. The territorial aspects of Spanish taxation can benefit those with properly structured international investment portfolios.
The FATCA and FBAR Reality
Whatever European tax benefits you enjoy, US citizens must still report foreign financial accounts exceeding $10,000 through FBAR filings. FATCA requirements add another layer, with European banks increasingly demanding extensive documentation from American account holders. Many expats find their US brokerages restricting services or closing accounts outright because of the regulatory burden.
Retirement Account Management Challenges in Europe
American expats frequently discover that major US brokerages like Schwab, Fidelity, and Vanguard impose restrictions on European residents. Required minimum distributions from traditional IRAs and 401(k)s keep coming regardless of where you live, but accessing funds or making investment changes becomes increasingly difficult from abroad.
The Foreign Earned Income Exclusion lets qualifying expats exclude significant foreign-earned income from US taxes, but it doesn’t apply to retirement account distributions, investment gains, or passive income. IRA withdrawals remain fully taxable to the US, which can produce double taxation depending on your European country’s tax treaty provisions.
Currency and Investment Considerations
Living in Europe whilst holding US dollar-denominated retirement accounts creates currency exposure that many expats overlook. A strengthening euro against the dollar can erode your purchasing power, and volatile exchange rates make retirement income planning harder. For long-term financial stability, diversifying into euro-denominated investments or considering offshore structures is worth serious thought.
Structuring Assets for European Living
Successful American expats in Europe often consolidate their US retirement accounts under dual-licensed advisers who can manage assets from European offices. This keeps you compliant with US regulations whilst bringing in local expertise on European tax treaties and reporting requirements.
Offshore fixed-interest investments offer another route for Americans seeking to move assets outside direct US jurisdiction whilst keeping access to professional management. These structures can provide steady income in multiple currencies, reducing both tax complexity and currency risk.
Annuity Considerations for Guaranteed Income
US annuities provide guaranteed monthly income with death benefits and 100% principal protection, features that matter a great deal for expats worried about healthcare costs and longevity risk. Properly structured annuities can offer tax-deferred growth and predictable income streams that also simplify European tax reporting.
Double Tax Treaty Navigation
US tax treaties with European countries do protect against double taxation, but getting the most out of those agreements takes real expertise. Treaty benefits for pension income, investment gains, and social security payments vary significantly by country. Portugal’s treaty offers different provisions than Spain’s or Italy’s, which affects how you should time withdrawals and set up your investment strategy.
Treaty tie-breaker rules become important when you’re spending time across multiple European countries. Your tax residence determination dictates which treaty applies and how your retirement income gets taxed in both jurisdictions.
