Leaving the US tax system, without paying more than the exit costs.
Renouncing citizenship or handing back a long-held Green Card is a tax event. Done carelessly it triggers a deemed sale of everything you own; planned properly, most people leave cleanly.
Figures on this page are stated for tax year 2025/26 UK · 2025 US. Thresholds change annually.

Covered or not is the whole question
Three tests decide whether the exit tax touches you: net worth above $2,000,000, average tax liability above the annual threshold, or — the one that catches people — inability to certify five years of full US tax compliance.
The compliance test means a clean-up filing often has to come first. Sequenced right, someone who would have been a covered expatriate frequently leaves as an uncovered one, owing nothing on the way out.

Green Cards don't expire for tax
Moving home doesn't end Green Card taxation — only formal abandonment on Form I-407 does, and holders of eight of the last fifteen years face the same exit tax as citizens. The year you file the form decides which side of that line you land on.

Life after exit, kept clean
Expatriation ends the worldwide net, not every thread: US-source income still needs W-8 forms and the right withholding, US property keeps its filing duties, and covered expatriates leave behind a punitive tax on future gifts to US family members.
We file the final dual-status return and Form 8854, reset your withholding paperwork, and map what the remaining US touchpoints will require — so the exit stays exited.

Questions we get about this
You file a final-year return covering the part of the year you were still a US person, along with Form 8854.
After that the obligation ends, provided the expatriation was properly completed and certified.
There can be. Gifts and bequests from a covered expatriate to US persons can attract a separate charge on the recipient.
It is a rarely discussed part of the regime and it can outlast the expatriation by decades.
Sometimes, through the timing of the expatriation and the composition of your assets, and always by being able to certify five years of compliance.
Planning is only possible before the fact, which is the argument for looking at it early.
It is a status test based on net worth, average tax liability over recent years, and whether you can certify five years of tax compliance.
Falling into it triggers the exit tax regime, so establishing where you sit before filing matters a great deal.
In broad terms it treats your worldwide assets as sold the day before expatriation and taxes the resulting gain, with an exclusion amount applied.
Certain assets - notably pensions and deferred compensation - are handled under separate rules rather than the deemed sale.
It can. Long-term permanent residents are subject to the same regime as citizens who renounce, based on how many of the last fifteen years you held the card.
People often assume only citizenship is caught, and that assumption is expensive.
Yes. Certifying five years of compliance is part of the process, and being unable to do so pushes you into covered status regardless of your numbers.
That is usually the deciding factor in sequencing catch-up filings ahead of expatriation.
