Renouncing US citizenship.
Learn moreFinal-year filings for those renouncing US citizenship or giving up long-term Green Card status, including covered-expatriate / exit-tax analysis.

Giving up US citizenship or long-term Green Card status triggers a final-year filing — Form 8854 — and possibly a 'mark-to-market' exit tax on unrealised gains in your worldwide assets. The covered-expatriate tests are mechanical: net worth above $2m, average tax over a threshold, or compliance gaps in the prior 5 years. Cross any line and the entire portfolio is treated as sold the day before you renounce. Smart sequencing — pre-renunciation gifting, basis step-ups, asset rebalancing — can move you out of covered status before you sign at the embassy.
