Renouncing US citizenship is a permanent, irrevocable decision with significant tax consequences. This guide covers the exit tax (IRC §877A), FATCA obligations, the 7-step renunciation process, and the most tax-optimal second passports for former Americans.
The exit tax treats covered expatriates as if they sold all worldwide assets at fair market value on the day before expatriation. Covered expatriates are those with net worth over $2M, average annual tax liability over $201,000 (2024), or who cannot certify 5-year tax compliance. Unrealized gains above the $866,000 exclusion (2024) are taxed at capital gains rates.
US persons must file Form 8938 (FATCA) for foreign financial assets over $50,000, FBAR (FinCEN 114) for foreign accounts over $10,000, and potentially Forms 5471, 5472, and 3520. All filings must be current for the 5 years before renunciation. Non-compliance makes you a covered expatriate by default.
State Department renunciation fee: $2,350 (highest in the world). Tax attorney consultation: $500–$5,000+. Tax preparation for 5-year compliance: $2,000–$15,000+. Total typical cost: $5,000–$25,000+ before any exit tax liability.
