◉ Expatriation & Renouncing
Expatriation return
The final US tax filing when you renounce US citizenship or give up long-term Green Card status.
Short answer
Anyone who renounces US citizenship, or gives up a Green Card held in 8 of the last 15 years, must file Form 8854 with a final dual-status return. You are a 'covered expatriate' — and exposed to the exit tax — if your net worth is $2 million or more, your average tax liability exceeds the inflation-indexed threshold, or you cannot certify five years of tax compliance.

Our approach
The exit tax, modelled before you sign.
Renouncing US citizenship or giving up a long-held Green Card is an irreversible step with a tax test attached. Whether you are a 'covered expatriate' — and whether the exit tax bites — turns on net worth, average tax liability and five clean years of compliance, and the modelling has to happen before you file Form 8854, not after.
We run the covered-expatriate analysis first, show you where you stand against each threshold, and sequence any catch-up filings so you are compliant before expatriation rather than caught out by it.
- Covered-expatriate status tested against all three thresholds up front
- Exit-tax exposure on unrealised gains modelled before Form 8854 is filed
- Pre-expatriation compliance sequenced so the five-year test is actually met
