US Expatriation and Exit Tax

Concept

Expatriation is the legal end of U.S. citizenship or, for certain long-term green card holders, the end of U.S. tax residency. It is not a shortcut around unresolved tax filings. The U.S. tax system uses a separate covered-expatriate regime, exit tax rules and Form 8854 reporting.

The IRS explains the tax side on its expatriation tax page. The State Department explains the nationality side on Relinquishing U.S. Nationality Abroad.

Who is in scope

The regime can apply to U.S. citizens who relinquish citizenship and to long-term lawful permanent residents who terminate U.S. residency for tax purposes. A long-term resident is generally a lawful permanent resident in at least 8 of the last 15 tax years ending with the year residency ends. A green card holder should not assume that abandoning the card ends all tax issues. Treaty positions, long-term resident status and Form 8854 can still matter.

The order of operations is the whole game. Valuations, basis, currency history and residency counts are far easier to establish before the consular or immigration event than to reconstruct afterwards, when the record is effectively frozen.

Covered expatriate tests

Covered expatriate status is generally tested through three screens: net worth, average annual net income tax liability and five-year tax compliance certification.

Use the current Instructions for Form 8854 for the year at issue, because the income tax test and the exclusion amount are adjusted annually.

Exceptions for dual citizens and minors

Two narrow groups can avoid covered-expatriate status even after crossing the net worth or income thresholds. The first is a dual citizen from birth who still holds, and is taxed as a resident of, the other country, and who has been a U.S. resident in no more than 10 of the last 15 tax years. The second is a person who relinquishes citizenship before age 18½ after no more than 10 years of U.S. residency. Neither relief is automatic: both still require certifying five years of U.S. tax compliance on Form 8854, so the certification test stays the real gate.

Exit tax mechanics

For covered expatriates, the exit tax can apply a mark-to-market regime as if property were sold the day before expatriation. The net gain is then reduced by a statutory exclusion — US$910,000 for 2026 (US$890,000 for 2025), adjusted annually — before tax applies. Deferred compensation, tax-deferred accounts and interests in certain trusts have separate treatment and sit outside this calculation.

The planning file should include a balance sheet, asset basis, valuation support, currency history, retirement accounts, trusts, companies, PFICs, CFCs, crypto, real estate and debt. A clean immigration event does not fix a missing tax valuation.

Three categories outside mark-to-market

Not every asset runs through the deemed-sale calculation; three classes have their own regimes. Eligible deferred compensation from a U.S. payer escapes the upfront charge if the expatriate waives any treaty rate and lets the payer withhold 30% on each future payment. Ineligible deferred compensation is treated as received in a lump sum, at present value, the day before expatriation. Specified tax-deferred accounts — a traditional IRA is the textbook case — are treated as fully distributed the day before, with full income inclusion but no early-withdrawal penalty; a Roth behaves differently, which is where the Roth-abroad analysis matters. Interests in non-grantor trusts face 30% withholding on each distribution rather than a single exit charge.

Electing to defer the exit tax

A covered expatriate who cannot, or would rather not, pay the mark-to-market tax at once can elect, asset by asset, to defer it until the property is actually sold. The price is real: the IRS requires adequate security, usually a bond or letter of credit, an irrevocable waiver of any treaty provision that would block collection, and interest running at the standard underpayment rate until payment. The election converts one large bill into a long-term, collateralised liability, which suits illiquid holdings such as a private company stake or real estate far better than a liquid portfolio.

Section 2801: the bill that lands on U.S. recipients

Expatriation does not close the file for the family. Under section 2801, a U.S. citizen or resident who later receives a covered gift or covered bequest from a covered expatriate pays a transfer tax at the top estate and gift rate — 40% — on the amount above the annual exclusion, US$19,000 for 2026. The charge sits on the recipient, not the departed expatriate, and it does not expire: a gift made years after the exit still counts. Treasury finalised the rules in January 2025 for transfers received on or after 1 January 2025, and the IRS released Form 708 to report and pay it.

Planning sequence

The order matters. First, confirm citizenship or green card facts. Second, clean up five years of federal tax compliance. Third, model covered-expatriate status and exit tax. Fourth, restructure only where lawful and defensible before the expatriation date. Fifth, coordinate the nationality or green card termination process. Sixth, file the final-year return and Form 8854 correctly.

A person considering expatriation should also evaluate future U.S. gifts and bequests, U.S. beneficiaries, U.S. investments, immigration access, banking and estate planning. Tax is only one part of the decision.

Checklist

• Confirm whether the person is a U.S. citizen or long-term green card holder.
• Reconstruct five years of U.S. tax filings and payments.
• Identify missing FBAR, Form 8938, CFC, PFIC, trust and entity forms.
• Prepare a current worldwide balance sheet with basis and valuation support.
• Model covered-expatriate status against all three tests before the legal expatriation event.
• Review trusts, retirement accounts, deferred compensation and company ownership.
• Coordinate U.S. tax counsel, immigration counsel and local advisors.
• Calendar the final return, Form 8854 and post-expatriation filing obligations.

Common mistakes

• Renouncing first and asking tax questions later.
• Ignoring long-term green card holder rules.
• Failing the five-year certification test because old filings were incomplete.
• Valuing private companies, crypto or trusts after the event without support.
• Forgetting PFIC, CFC, FBAR, Form 8938 or Form 3520 cleanup.
• Treating expatriation as a family-wide solution when only one person changes status.

Advisor trigger

Use a U.S. tax attorney before booking a consular appointment, filing green card abandonment, taking a treaty nonresident position, moving assets, transferring shares, changing trusts or making large gifts.
