Renouncing US Citizenship: Exit Tax, Process, and What Comes After

A growing number of Americans abroad are now acting on a decision they used to only talk about. Enough changed in the past year that most of the renouncing US citizenship tax guidance sitting online is already out of date. The consular fee dropped by 80% in April 2026, the exit tax thresholds moved up, and a wealth transfer tax that sat dormant for sixteen years finally has a form, a deadline, and enforcement behind it.

Why Americans Are Giving Up the US Passport

The United States taxes citizens on worldwide income regardless of where they live, an approach it shares with only one other country, Eritrea. A US citizen who has lived in Lisbon for twenty years still files a Form 1040 every April.

For decades this was theoretical because nobody was checking. The Foreign Account Tax Compliance Act (FATCA), enacted in 2010, forced foreign banks to report American account holders or face 30% withholding on their US revenue, and compliance became cheaper than the alternative. Our guide to FBAR and FATCA reporting covers what gets reported and by whom.

Before 2009, renunciations averaged 200 to 400 a year; they peaked at 6,705 in 2020, dipped, then rebounded to roughly 5,000 in 2024, with 2025 setting a fresh record.

Banking drives much of it. Foreign institutions routinely refuse American clients because the compliance reporting costs more than a retail account is worth to the bank. In practice that means a Swiss couple denied an ordinary mortgage and an Australian couple whose accounts were closed without warning, purely over citizenship.

A 2025 expatriate survey found about one in ten Americans abroad intends to renounce, and the cohort skews young: Gen Z (38% of planned renunciations) and Millennials (36%) cite social policy, while Gen X points to immigration policy. But over 75% said they felt financially unprepared for the exit tax, which is why intention rarely becomes execution.

The US Citizenship Renunciation Process, Step by Step

Renunciation cannot be done inside the United States. It happens in person, in front of a diplomatic or consular officer, at an embassy or consulate abroad. There is no online option, no mail-in form, and no sending a lawyer in your place.

1. Secure a second nationality first. Consular officers require proof of another citizenship, usually a valid foreign passport or naturalisation certificate. Statelessness is not an acceptable outcome and they will not process you into one.
2. Book the appointment. Many posts split this into an electronic or telephone review followed by the mandatory in-person appearance.
3. Complete Form DS-4079, the questionnaire on loss of US nationality and your ties to both countries.
4. Sign Form DS-4081, the statement of understanding, which sets out every consequence in writing.
5. Swear the oath on Form DS-4080. Once it is administered, you have legally relinquished your citizenship.
6. Wait for adjudication. The file goes to the State Department in Washington, which issues Form DS-4083, the Certificate of Loss of Nationality.

The physical certificate can take months, but the effective date of expatriation for both immigration and tax purposes is the date you swore the oath. The decision is irrevocable too, with no cooling-off period and no route back other than qualifying for a visa like any other foreign national.

What It Costs Now: The $450 Fee and the Appointment Backlog

In 2010 renouncing was free. The State Department then introduced a $450 fee and raised it to $2,350 in 2015, one of the highest exit fees in the world by a wide margin.

The Association of Accidental Americans sued, arguing the charge was an unconstitutional barrier to a fundamental right under the Fifth and Eighth Amendments. The State Department published a final rule in the Federal Register on 13 March 2026, signed by Secretary of State Marco Rubio, reversing the increase. Effective 13 April 2026, the fee returned to $450.

Two things follow. If you expatriated before 13 April 2026, you paid $2,350 and there is no refund mechanism. And cutting a price by 80% predictably spiked demand: thousands deliberately waited for the drop, new applicants piled in behind them, and the global queue for renunciation appointments now exceeds 30,000 people. In London, Paris and Zurich, appointments are rationed and waits run well beyond a year.

Now I know what you're thinking. Waiting for the cheaper fee saved you $1,900. But you remain a US taxpayer on worldwide income until the day you take the oath, so every month in the queue means another Form 1040, another FBAR, another set of accountant fees, and more time for your portfolio to appreciate its way toward the exit tax thresholds. An extra eighteen months in the system costs more in professional fees than the fee cut ever saved you.

Are You a Covered Expatriate? The Three Tests

Everything painful about expatriation attaches to one label: covered expatriate. Avoid it and renunciation is largely administrative. Attract it and you are into Section 877A, introduced by the HEART Act of 2008 to extract a final toll on wealth accumulated under US jurisdiction.

The regime catches citizens who renounce and long-term residents, meaning green card holders who held permanent resident status for at least 8 of the 15 taxable years ending with the year of expatriation. Long-term residents formally abandon status by filing Form I-407.

Let's take a look at the three tests, because failing any one of them on its own is enough.

• The net worth test: global net worth of $2 million or more on the date of expatriation. This threshold was set in 2008 and has never been indexed. A test written to catch the genuinely wealthy now routinely catches a retired teacher in Sydney with a paid-off house and a superannuation balance.
• The average annual net income tax liability test: average annual net US income tax liability over the five tax years ending before expatriation above $211,000 for 2026 (it was $206,000 for 2025). This measures tax actually paid rather than gross income, so it takes a sustained high income to trip.
• The certification test: failure to certify under penalties of perjury that you have complied with all federal tax obligations for the five preceding taxable years, done on Form 8854.

There are narrow exceptions. Someone who was a dual citizen at birth, retained the other citizenship, and has not been a US resident for more than 10 of the past 15 taxable years escapes the net worth and income tax tests. So does someone who renounces before turning 18 and a half without having lived in the US for more than 10 years. This matters a great deal to dual citizens who never really lived in the US.

The catch is that neither exception touches the certification test. You still file Form 8854 and certify five clean years, and if you do not, the exception evaporates.

How the Exit Tax Works When You Renounce

If you are a covered expatriate, Section 877A treats all of your worldwide property as sold at fair market value on the day before your expatriation date. Nothing is actually sold. It is a deemed sale, a legal fiction that produces a very real tax bill.

Take fair market value, subtract adjusted cost basis, and the net unrealised gain is your number. The statutory exclusion shelters the first slice: $910,000 for 2026, up from $890,000 in 2025 and $866,000 in 2024. Anything above that is taxed at applicable US capital gains rates and reported on your dual-status return for the year of expatriation.

Consider Sarah, who founded a software company in Berlin twelve years ago. Her stake is worth $6 million on paper with a basis close to zero, and she has never sold a share. On expatriation she has $6 million of deemed gain, $910,000 comes off the top, and she owes capital gains tax on roughly $5.09 million. Nobody wired her anything. Finding that cash usually means a premature sale, a loan against the position, or a secondary German tax bill with no matching US credit to offset it.

The Code lets you elect to defer payment until the assets are actually sold, which in theory solves the liquidity problem. In practice you must post adequate security such as an irrevocable bond, sign an irrevocable waiver of all treaty benefits, pay compounding interest on the deferred balance, and coordinate with the IRS facility in Austin, Texas for as long as you hold the asset. Most people read "irrevocable bond" and "treaty waiver" and decide to just pay. Our US exit tax explainer sets out the calculation in full.

The Assets That Escape Mark-to-Market (and Get Taxed Differently)

Here is the misconception that causes the most damage: that the $910,000 exclusion covers everything you own. It does not. Section 877A carves out retirement and deferred compensation assets and runs them through separate rules that are frequently worse.

• Eligible deferred compensation: a plan with a US payor, such as a traditional 401(k) or domestic pension. File Form W-8CE with the plan administrator within 30 days of expatriation and irrevocably waive your right to reduced treaty withholding, and nothing is taxed on exit. Instead the administrator withholds a flat 30% on every distribution you ever take.
• Ineligible deferred compensation: foreign pensions (a UK SIPP, an Australian superannuation fund), Section 457 nonqualified plans, or a domestic plan where you missed the W-8CE deadline. The entire present value of the accrued benefit is treated as distributed the day before expatriation, added to that year's gross income and taxed at ordinary rates. No early withdrawal penalty applies. Thirty years of pension savings simply land in a single tax year at the top marginal bracket while the money stays locked inside the plan. This is no bueno.
• Specified tax-deferred accounts: IRAs and HSAs are deemed fully distributed the day before expatriation. The full balance is taxed at ordinary income rates, again with no early withdrawal penalty, and the mark-to-market exclusion shelters none of it.
• Interests in non-grantor trusts: left outside the deemed sale, but the trustee withholds 30% on every distribution made to you afterwards.

A covered expatriate holding a large foreign pension can face a bigger bill from these rules than from the mark-to-market tax on their entire investment portfolio.

Form 8854 and the Five-Year Compliance Trap

Of the three tests, certification is the one that catches the most people (hint: it has nothing to do with how much money you have).

Consider John, a schoolteacher in Ontario who was born in Buffalo and left at four months old. Net worth $300,000, five-year US tax liability of zero. He renounces, forgets Form 8854 or files it incorrectly, and he is a covered expatriate. Not because he is rich, but because of a form.

Miss the Form 8854 deadline (15 April, or 15 June for filers abroad) and you pick up an immediate $10,000 civil penalty and automatic covered status. An IRS finding of historical errors, omissions or unfiled information returns in any of the five preceding years does the same. Form 8854 is a full ledger of your financial life, listing every asset with cost basis and fair market value at departure, signed under penalties of perjury. File it late or loosely and you are a covered expatriate on paper, whatever your actual balance sheet says.

Sequencing matters most here. You clean up the five-year history before you swear the oath, not after. The Streamlined Foreign Offshore Procedures allow three years of delinquent returns and six years of FBARs without the standard penalty regime, and our walkthrough of the streamlined filing procedures covers who qualifies. There is also the Relief Procedures for Certain Former Citizens, a narrow penalty-free path for people with net worth under $2 million and minimal aggregate liability, open even to people who never held a Social Security Number. Getting the order right is exactly what our cross-border tax advisory work exists for.

Section 2801: The Tax Your Heirs Pay, Forever

If the exit tax is the toll at the border, Section 2801 is the tail that never stops wagging. The HEART Act created a special transfer tax on gifts and bequests from a covered expatriate to any US citizen or resident, regardless of when the transfer happens or where the assets sit. Congress did not want renunciation to double as a clean exit route for family wealth.

The structural twist is that it reverses how US transfer taxes normally work. Estate and gift tax is levied on the donor or the decedent's estate. Section 2801 shifts the liability onto the US recipient. Your daughter in Chicago pays it, at the highest applicable estate tax rate of 40% on anything above the annual gift tax exclusion. And paying that 40% gives her no step-up in basis either, so a later sale carries embedded capital gains on top.

There is no ten-year expiry and no statute of limitations: a bequest made forty years after renunciation still triggers the tax on the US beneficiary. The only real escapes are a recipient who is not a US person, or an expatriate who re-enters the US estate tax system by re-establishing US domicile before death.

For sixteen years this sat unenforced with no filing mechanism. That ended with final regulations (TD 10027) published on 14 January 2025, which introduced Form 708. For transfers received during 2025, US beneficiaries file the first-ever Form 708 and pay by 15 July 2027. Anyone with covered expatriates in the family tree should read this alongside the rules on cross-border inheritance tax, because the interaction decides whether US-person heirs belong in the structure at all.

Life After Renunciation: Visas, Social Security, and US Assets

You lose the unconditional right to enter the United States on the day you take the oath. From then on you travel like any other foreign national, on ESTA under the Visa Waiver Program if your new passport qualifies, or on a B1/B2 visitor visa if it does not.

What about the Reed Amendment? Enacted in 1996 and codified at 8 U.S.C. § 1182(a)(10)(E), it makes any former citizen who renounced for tax reasons permanently inadmissible. On paper it is alarming. In practice it is a dead letter, because Homeland Security cannot determine tax motive and the IRS, the only agency that could, is barred from sharing taxpayer data with immigration authorities under 26 U.S.C. § 6103. No implementing regulations were ever issued, and a consular officer can invoke it only if the applicant affirmatively admits tax motivation. Between 2002 and 2015, two people worldwide were refused admission under it.

Social Security survives renunciation. Eligibility comes from 40 work credits (about ten years of covered US earnings) rather than from citizenship, but whether you get paid depends on where you live. Countries with a totalization agreement, such as the UK, Canada and Australia, keep paying normally. Without one, benefits can be suspended after six consecutive months abroad, and in restricted countries such as Cuba and North Korea they stop entirely. The tax character changes too, since as a non-resident alien you face 30% withholding on 85% of the benefit, an effective 25.5% at source, with treaty relief available in some jurisdictions and no standard deduction to fall back on.

Then there are the assets left behind. A non-resident alien gets a US estate tax exemption of just $60,000 on US-situs assets, against the multi-million dollar exemption a citizen enjoys. A brokerage account holding US stocks, a condo in Miami or a stake in a US LLC can generate a serious estate tax bill for your heirs, with treaty relief varying by country. US real estate sales trigger FIRPTA withholding at closing, and many US brokers close accounts once your address and tax status go foreign, so settle the custody question before you renounce, not after.

Planning Before You Sign

So what does all of this mean for you? Mostly that the pre-renunciation window decides the outcome, and that it is measured in years rather than months.

• Control the valuation date. The mark-to-market tax is measured the day before expatriation, so if your company is mid-raise at a fresh valuation or your portfolio is at an all-time high, that is the number the IRS uses. Timing the oath around a valuation event is legitimate and consequential.
• Manage the net worth test. Spouses are assessed individually, so the allocation of jointly held property matters. Gifting assets to a spouse or into structures beforehand can bring you under $2 million, provided it happens well in advance, though gifts to a non-citizen spouse have their own annual limit.
• Sequence around liquidity events. Sell the business first and you pay real capital gains tax, then hold cash that still counts toward the $2 million. Renounce first and you may pay phantom tax with no cash to cover it. Which is better depends on basis, valuation and residence, and it needs modelling rather than instinct.
• Get the second passport first. No consular officer will render you stateless, and naturalisation timelines in most jurisdictions run three to ten years. This is the longest lead item on the list.
• Pick the year deliberately. The Section 877A exclusion indexes upward each year ($866,000 in 2024, $890,000 in 2025, $910,000 in 2026) and so does the income tax liability threshold. The $2 million net worth test does not move, which means asset appreciation works against you in every year you wait. Combine that with a consular queue running past twelve months at the major posts and the appointment should be booked long before the planning is finished.
