Millions of Europeans are American taxpayers without knowing it. In 2026, with the renunciation fee cut by 80%, the three exits from the trap deserve a fresh look.
She was born in Boston during her father's postdoc and left at eleven months. He was born in Lyon to an American mother and has never held a US passport. Both received, decades later, the same letter from their bank: please provide a Form W-9 and your US taxpayer identification number. Both are accidental Americans, citizens of the United States by birthright or by descent, and therefore, under the American rule of citizenship-based taxation, lifelong US taxpayers who have never filed a US return.
The predicament is structural, not personal: it sits at the intersection of an unusual nationality law, an unusual tax jurisdiction, and FATCA, the reporting machinery that turned European banks into the discovery mechanism. And 2026 has changed its economics: since April, the consular fee for renouncing US citizenship has fallen from 2,350 dollars to 450 dollars, removing the barrier that kept many accidental Americans frozen between options.
Three exits exist: comply, renounce, or wait. This article examines each honestly, in the only order that works. Part I explains how one becomes an accidental American and how one gets discovered. Part II measures what the status actually costs. Parts III and IV detail the compliance and renunciation routes. Part V says what we think of waiting.
I. Becoming, and being discovered
A. Three doors into citizenship
American citizenship arrives through doors people forget they passed. Birth on US soil confers it regardless of the parents' status or the length of the stay: the child born during a posting, a degree, a vacation. Birth abroad to an American parent transmits it where the parent meets physical-presence conditions, often satisfied without anyone documenting it. And the green card, though not citizenship, creates the same tax status: a lawful permanent resident remains a US taxpayer until the card is formally abandoned, not merely expired in a drawer, and a long-term holder who lets it lapse can even face the expatriation regime described below. In each case the tax consequence attaches automatically; no election, no awareness, no passport required.
B. FATCA, the discovery scene
For decades the status was theoretical. FATCA ended that: European banks must identify accounts with US indicia, a US birthplace first among them, and report them to the American authorities. The letter asking for a W-9 and a Social Security number is now the standard first act of every accidental American file, sometimes escalating to threats of account closure when the client cannot produce a number they never had. Two truths frame everything that follows: the data is already flowing, as we explained in our analysis of the ten structural mismatches, and the bank's letter is not an IRS examination, which means every repair option remains open, but on a clock.
II. What the status actually costs
A. Usually little tax, always many forms
The first surprise of the accidental American is the obligation; the second is that the tax itself is often modest. Foreign tax credits for European income tax paid, and the foreign earned income exclusion, absorb most or all of the US liability for ordinary salaried lives in high-tax Europe. The real burden is the reporting layer, decoupled from tax due: the annual return, the FBAR for accounts crossing the 10,000 dollar aggregate threshold, with the traps of assurance-vie, PEA and forgotten accounts we have inventoried, and Form 8938. The European savings toolkit aggravates everything: local funds are PFICs, punitively taxed and separately reported, so that the better the person saved at home, the worse their American position.
B. The costs beyond tax
Three non-tax costs complete the picture. Banking access: some European institutions simply close or refuse accounts with US indicia rather than bear FATCA compliance. The missing Social Security number: a citizen who never lived an adult life in America typically has none, and obtaining one from abroad is a months-long consular process that gates most compliance routes. And succession: an unresolved American status does not die with its holder, it complicates the estate, the heirs' banking, and any US assets, which is why we treat the accidental American question as a family matter rather than an individual one.
III. Exit one: comply
A. The streamlined route
For the accidental American who keeps the citizenship, the path is the one we detailed in our analysis of the streamlined procedures: three years of returns, six years of FBARs, a non-willfulness certification on Form 14653, and no penalty at all under the foreign variant. Accidental Americans are the paradigm of non-willfulness, and their files are usually the cleanest we handle. The practical gates are administrative: the Social Security number must be obtained first, and the French or European tax mirror must be checked so that the two countries' filings tell one story.
B. What compliance commits you to
Honesty requires the second half of the sentence: streamlined is an entrance, not an exit. The compliant accidental American becomes a permanent US filer, every year, with a portfolio that must be restructured around PFIC rules and products chosen for American compatibility rather than local advantage. For a person with a genuine American dimension to their life, career mobility, US assets, family, the commitment is worth it. For a person whose America is a birth certificate, the annual cost of compliance is precisely what pushes the analysis toward the second exit.
IV. Exit two: renounce
A. The mechanics, and the 2026 change
Renunciation is a consular act: an appointment, an oath, and a Certificate of Loss of Nationality. Its historic financial barrier fell this year: the State Department's final rule of 13 March 2026 cut the fee from 2,350 dollars to 450 dollars, effective 13 April 2026 (Federal Register). The tax side is untouched by that rule and is where the real analysis lives: every expatriate files Form 8854 with their final return, on pain of a 10,000 dollar penalty (IRC section 6039G), and the statute sorts expatriates into two classes. A covered expatriate, one whose net worth reaches 2 million dollars, whose average annual net income tax liability exceeds an indexed threshold (206,000 dollars for 2025), or who cannot certify five years of tax compliance, faces the section 877A exit tax: a deemed sale of worldwide assets the day before expatriation, above an indexed exclusion (890,000 dollars for 2025). We will devote a dedicated article to the 877A mechanics; what matters here is the third test: renouncing without being compliant makes you covered automatically, whatever your wealth.
B. The relief procedures: the accidental American's dedicated door
For the core accidental profile, the IRS maintains a tailored route: the Relief Procedures for Certain Former Citizens (irs.gov). Open to individuals who relinquished citizenship after 18 March 2010, or will relinquish it, who have never filed as US citizens, whose conduct was non-willful, whose net worth is below 2 million dollars both at expatriation and at submission, and whose aggregate US tax liability over the expatriation year and the five prior years does not exceed 25,000 dollars, the procedures accept six years of returns and grant the certification of compliance without collecting the taxes or any penalty. The sequence they enable is the clean one: renounce at the consulate, then file the relief package, exit certified and uncovered. For eligible profiles, it is close to an administrative amnesty, and the fee reduction has just removed the last excuse to postpone the decision.
C. What renunciation does not do
Three lucidity points before the oath. Renunciation is irrevocable and personal: it does not undo the past, so pre-renunciation compliance failures must still be resolved, by streamlined or by the relief procedures. It has non-tax consequences: entering the United States thereafter happens as an alien, with the visa regime that implies. And for the wealthy accidental American above the covered thresholds, renunciation is not a formality but a taxable event to be planned, sometimes over years, which is exactly the sequencing discipline we preach for founders' mobility applied in reverse.
V. Exit three: wait, and why it fails
A. The case for waiting, stated fairly
Waiting has a constituency and, in narrow cases, arguments: the elderly person with no US assets, no travel plans and modest accounts, for whom the practical probability of enforcement is low and the cost of any repair high relative to remaining life plans. We state the case because intellectual honesty requires it, and because pretending every situation demands immediate six-year reconstructions is the compliance industry's vice, not ours.
B. Why it fails as a strategy
For everyone else, waiting mistakes a deteriorating position for a stable one. The data flows annually whether or not the person acts; unfiled years never close, since limitation periods do not run on returns never filed; banking pressure escalates toward closure; the streamlined procedures and the relief procedures are administrative creations that the IRS can restrict or withdraw, and eligibility for both ends the day an examination opens. Waiting also transfers the problem, unresolved and enlarged, to heirs. Our position is accordingly simple: waiting is a decision to be taken once, with counsel, eyes open, for the rare profiles it genuinely fits, and never the default produced by not deciding.
C. The decision in one paragraph
Keep the citizenship if America is part of your life's architecture: then comply, by streamlined, and restructure the portfolio. Renounce if America is an accident of birth you do not intend to activate: then use the relief procedures if eligible, in the right order, consulate first, package second. And treat waiting as what it is, a wager that discovery, regulation and mortality will all cooperate. Since April 2026, the price of indecision exceeds the price of the exit.
Conclusion
The accidental American is the purest product of the structural mismatches between American and European tax logic: a taxpayer created by a birthplace, discovered by a bank, and offered exits whose economics shifted this year. Compliance through the streamlined procedures suits those who keep the citizenship; renunciation, now at 450 dollars, with the relief procedures certifying compliance without tax or penalty for eligible profiles, suits those who close the American chapter; waiting suits almost no one, though it deserves an honest hearing.
The order of operations is the invariant: assess willfulness and exposure with counsel, secure the Social Security number or the relief eligibility, check the European mirror, and only then execute, in the sequence the chosen exit requires. An accidental status handled this way resolves in months. Handled by silence, it compounds for a lifetime and then becomes the heirs' problem.
Frequently asked questions
I was born in the United States but left as a baby. Am I really a US taxpayer?
Yes. Birth on US soil confers citizenship regardless of how briefly you stayed, and American taxation follows citizenship, not residence. You have been required to file US returns and, above the thresholds, foreign account reports for your entire adult life. The practical exposure depends on your situation, and repair routes exist with zero penalty for non-willful profiles, but the status itself is not in doubt.
My bank is threatening to close my account because I have no US tax number. What do I do?
Treat it as the starting gun, not the deadline. The bank needs a W-9 with a Social Security number: apply for the number through the consular process now, since it takes months and gates every compliance route. Then choose the exit, compliance or renunciation, with counsel. The bank's letter is not an IRS examination, so the streamlined procedures and the relief procedures remain open, but the data is flowing and the window should be treated as closing.
How much does it cost to renounce US citizenship in 2026?
The consular fee is 450 dollars since 13 April 2026, down from 2,350 dollars. The real cost is fiscal: you must exit compliant, either by prior streamlined filings or through the Relief Procedures for Certain Former Citizens, which for eligible profiles (net worth under 2 million dollars, aggregate six-year tax under 25,000 dollars, non-willful, no filing history) certify compliance without collecting tax or penalties. Above the covered expatriate thresholds, renunciation triggers the section 877A exit tax and must be planned, not booked.
Can I simply do nothing and hope it passes?
You can, and in rare configurations, typically elderly persons with no US assets or travel and modest accounts, it can be a defensible considered choice. As a default it fails: unfiled years never close, FATCA reporting continues annually, banks escalate to closure, the amnesty procedures are administrative and revocable, and the problem passes enlarged to your heirs. If waiting is chosen, it should be chosen once, with counsel, and revisited at every life event.
