US Worldwide Taxation Basics
- US citizens and green card holders owe federal income tax on worldwide income
- This obligation continues even if you live and work abroad for decades
- Filing thresholds are the same as for domestic taxpayers; most expats must file annually
- The US is one of only two countries that tax citizens regardless of residency
Foreign Earned Income Exclusion (FEIE)
- Allows qualifying expats to exclude a set amount of foreign earned income from US tax
- You must meet the bona fide residence test or physical presence test (330 days abroad)
- The exclusion applies only to earned income, not investment income or pensions
- Electing the FEIE requires Form 2555 and is difficult to re-elect if revoked for five years
Foreign Housing Exclusion and Tax Treaties
- The housing exclusion covers qualifying housing expenses above a base amount abroad
- Eligible expenses include rent, utilities, and insurance but not mortgage payments
- Tax treaties between the US and other countries can reduce or eliminate double taxation
- Totalization agreements prevent dual Social Security taxation in treaty-partner countries
FBAR and FATCA Reporting
- FBAR (FinCEN 114) is required if foreign account balances exceed $10,000 at any point
- FATCA (Form 8938) requires reporting foreign financial assets above higher thresholds
- The two filings overlap significantly but go to different agencies
- Penalties for non-filing are severe, up to $10,000 per violation for FBAR
State Tax and Retirement Account Issues
- Some states continue to tax former residents who maintain ties like a home or license
- Establishing domicile in a no-income-tax state before moving abroad can sever state ties
- US retirement accounts remain accessible abroad but some custodians restrict non-US addresses
- Foreign mutual funds are taxed punitively as PFICs; use US-domiciled funds instead
Exit Tax and Expatriation
- Renouncing citizenship or surrendering a green card can trigger an exit tax
- Covered expatriates are treated as selling all assets at fair value before expatriation
- You are covered if net worth exceeds $2 million or average tax liability exceeds a threshold
- Deferred compensation and certain trust distributions face 30% withholding after exit
Common Mistakes Expats Make
- Failing to file US returns because they assume living abroad eliminates the obligation
- Investing in foreign mutual funds without understanding the punitive PFIC tax regime
- Not comparing FEIE vs foreign tax credits, which sometimes produce a better result
- Overlooking state filing requirements, especially in high-tax states with broad sourcing
