TL;DR
Exit Tax (IRC §877A) applies to US citizens who renounce citizenship and Green Card holders who terminate long-term residency (held GC for 8 of the last 15 tax years).Triggers if you're a "covered expatriate": net worth ≥$2M, average annual income tax >$201,000 (2026, indexed), OR failure to certify 5-year compliance.Mark-to-market treatment: all worldwide assets are treated as sold the day before expatriation. Gain is taxed at applicable rates.Exclusion of first $890,000 (2026) of gain. Above that, regular capital gain rates (max 20% + 3.8% NIIT) on capital assets; ordinary rates on income-producing items.Special rules for retirement accounts (deferred distribution model with 30% withholding on payouts), deferred compensation, trusts.Form 8854 — Initial and Annual Expatriation Statement. Must file in renunciation year. Failure = automatic covered expatriate status.The financial decision goes beyond Exit Tax: future US estate/gift tax exposure on US-situs assets, loss of US-citizen tax preferences, banking implications.Who is affected
Three categories trigger Exit Tax:
US citizens who renounce citizenship (at a US embassy/consulate, swearing the oath of renunciation).Long-term US residents (Green Card holders for 8 of last 15 tax years) who terminate residency by: - Surrendering the GC (Form I-407), OR
- Becoming a treaty resident of a country with a US tax treaty and claiming non-resident status.
Tax expatriates under IRC §877A — those who give up status AND meet the "covered expatriate" tests.Are you a "covered expatriate"?
You are if any of:
Net worth ≥$2 million on the date of expatriation, ORAverage annual net income tax for the 5 years before expatriation >$201,000 (2026, indexed to inflation), ORFailure to certify 5-year tax compliance on Form 8854.Meet ANY → covered expatriate → Exit Tax applies.
The failure-to-certify trigger is critical: if you owe back-year filings (Streamlined or otherwise), the IRS treats you as a covered expatriate by default, even if you wouldn't otherwise hit the wealth/income tests.
How the Exit Tax works
Mark-to-Market regime (IRC §877A(a))
All your worldwide assets are deemed sold for fair market value on the day before your expatriation date. Gain is computed: (FMV − basis).
Applies to:
Stocks and bondsReal estateBusiness interests (operating businesses, partnerships)CryptocurrencyPersonal-use assets (homes, art) above basisForeign assetsExclusion: First $890,000 (2026) of net gain is excluded. Above that:
Long-term capital assets: 20% capital gain rate + 3.8% NIIT = 23.8% max.Short-term gains or ordinary-income items: full marginal rate (up to 37%).Section 1231 property (depreciable real/personal property used in trade): mixed treatment.Deferred compensation
Special rules. Two paths:
"Eligible deferred comp": certain plans you can elect to treat as deferred. Foreign payor must agree to 30% withholding when paid out. Tax deferred until distribution."Ineligible deferred comp": treated as paid out on expatriation day at PV → taxed in expatriation year.Also applies to 409A nonqualified deferred comp, foreign pensions in some cases.
Retirement accounts (IRC §877A(d))
IRA, 401(k), 403(b), etc., are NOT marked to market. Instead:
Taxed only when distributed.30% withholding mandatory at distribution (no treaty relief possible).You lose any qualified distribution treatment (Roth qualified withdrawals still tax-free, but treated as if treated by a non-US person).Trusts
Grantor trusts: pre-existing US treatment continues for grantor portion.
Non-grantor trusts: special inclusion rules — gain on transferred assets recognized.
Foreign trusts with US-person beneficiaries: continuing reporting under §679 etc.
Form 8854 — the mechanics
Form 8854 (Initial and Annual Expatriation Statement) is the critical form.
File in the year you expatriate:
Section I: identifying info, residency facts.Section II: 5-year compliance certification (yes/no).Section III: balance sheet — every asset by category with FMV, basis, deemed gain.Section IV: mark-to-market computation, exclusion calculation, deferred-comp elections.Section V: deferred tax election (you can elect to defer payment of the Exit Tax on certain assets if you post collateral with the IRS).Annual updates after expatriation:
If you elected deferred payment of Exit Tax on assets, file annual updates until paid in full.Even without deferred elections, file the next year confirming finalization.Failure to file Form 8854 = automatic covered expatriate status, plus $10,000 penalty per year for non-filing.
Estate and gift tax after expatriation
Non-US persons are subject to US estate tax on US-situs assets (US real estate, stock in US corporations, certain US partnership interests, tangible personal property in the US, US bank accounts in some cases) above a $60,000 lifetime exemption — much smaller than the $13.61M US-citizen exemption.
Gifts of US-situs property by a non-citizen to a US person are also subject to gift tax above the annual exclusion ($18,000 in 2025).
After expatriation, you retain US estate/gift tax exposure on US-situs assets. This matters if you:
Hold US real estateHave US-corp stock (Apple, Tesla, etc.)Plan to gift to US-resident childrenMany expatriates restructure US-situs holdings to non-US-situs ones before renunciation to minimize this.
Covered expatriate gifting penalty
IRC §2801: a US person who receives a gift or bequest from a covered expatriate is taxed at the highest gift/estate tax rate (40% in 2026) on the amount received above the annual exclusion. This is a recipient-side tax — your US-citizen children pay it on inheriting from you.
This is a major deterrent and often surprises clients.
The financial math — when does renunciation make sense?
Renunciation is rarely a tax-only decision. Other factors:
Loss of US passport / right to live/work in USVisa requirements for future US visitsInability to easily re-establish US tax residencyBanking — some foreign banks decline US persons, some decline expatriated US persons tooFinancially, renunciation can save tax if:
Future US tax obligation on worldwide income is large (high-income expat permanently abroad)You don't expect to return to live in USYou don't have US-situs assets you'd want to hold or gift to US personsExit Tax cost is bearable given your current portfolio gainsIt can be a poor decision if:
You expect to returnYou have unrealized gains > $890K exclusion (Exit Tax bill is large)You have US-citizen children / heirs (IRC §2801 hits them)Your foreign jurisdiction has high tax anywayPre-expatriation planning
If you're considering this, you have years of optimization opportunity:
Achieve 5-year compliance — file all back-year returns including FBAR before expatriation. Otherwise you're a covered expatriate automatically.Realize losses to offset future Exit Tax gain.Rebalance away from US-situs assets to non-US-situs (eliminates future estate exposure).Pre-fund retirement accounts (they're not marked to market).Establish foreign domicile and tax residency well before to use the GC long-term-resident timing.Time the renunciation for a year when you're in a low income bracket.Start 2-3 years before the target date.
