US Citizenship Renunciation Guide 2026

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 (IRC §877A)

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.

FATCA & Reporting Obligations

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.

The 7-Step Renunciation Process

  1. Secure a second citizenship first — you cannot renounce without another citizenship.
  2. Consult a US tax attorney specializing in expatriation.
  3. File all outstanding US tax returns (5 years of compliance required).
  4. Schedule a renunciation appointment at a US Embassy abroad (3–6 month wait).
  5. Attend the appointment, sign the Oath of Renunciation (DS-4080), pay the $2,350 fee.
  6. File Form 8854 with your final US tax return.
  7. Close or restructure US financial accounts.
