"I've been filing as a nonresident under the treaty, but I still have the green card. Did I already expatriate?" That question arrives almost word for word, and the answer is often yes. Green card holders who move abroad, retire overseas, or stop using their permanent residence assume that giving it back is a paperwork exercise. Once you've held the card 8 of the last 15 years, the exit tax rules under Section 877A apply to you on the same terms as a citizen. Three parts of that regime catch green card holders off guard, & the treaty one catches the most. It works without any of the paperwork described in our green card abandonment guide.
Can a Treaty Tie-Breaker Claim End Your Green Card Without Form I-407?
A treaty tie-breaker claim does end lawful permanent resident status for tax purposes, and IRC 7701(b)(6) is why. That section ends the status for federal tax purposes once the individual begins to be treated as a resident of a foreign country under a U.S. income tax treaty, does not waive the benefits of that treaty, and notifies the Secretary of that treatment. Notice is ordinarily given on Form 8833, the treaty-based return position disclosure, attached to the return. Nothing in that sentence asks you to hand the card to anyone.
The immigration document and the tax status come apart here. Your Form I-551 can be valid for another six years, sitting in a drawer, while the tax status it represents has already ended because of a position taken on page one of a return. IRC 877A(g)(2)(B) then defines an expatriate to include a long-term resident who ceases to be a lawful permanent resident within the meaning of 7701(b)(6), so the treaty termination is itself the expatriating act.
What makes this so common is that the treaty filing is usually correct. Someone relocates to Canada, Germany, or Australia for a job, becomes resident there under domestic law, and their preparer applies the Article 4 tie-breaker so the same salary is not taxed twice. The treaty answer is right. Section 877A never enters the conversation. Nobody goes back and re-runs the count.
What Sets Your Expatriation Date When You Never Filed Form I-407?
Your expatriation date is the earliest of four events under IRC 877A(g)(3), IRC 7701(b)(6), and the Form 8854 instructions. For most long-term residents only one of the four ever happens, and the treaty trigger is the one that happens without anyone noticing.
The Four Expatriation Triggers
Critical- You file Form I-407 with USCIS, or lodge it with a consular officer abroad.
- A final administrative or judicial determination that you abandoned lawful permanent resident status takes effect.
- You are removed, and the order becomes final.
- You begin being treated as a resident of a treaty partner country under a tie-breaker provision, you do not waive treaty benefits, and you notify the IRS of that treatment under Regulations section 301.7701(b)-7.
That last trigger is the one long-term residents overlook. Someone can keep the physical green card, never file the I-407, and still have expatriated years earlier because of a treaty position their return preparer took without connecting it to Section 877A.
The date isn't a formality. It fixes the five taxable years tested for the average income tax threshold and for the Form 8854 compliance certification, and it sets the day-before valuation date for the deemed sale. Move the date back four years and every one of those inputs changes.
Does a Treaty Year Count Toward the 8-of-15 Long-Term Resident Test?
A treaty year does not count toward the 8-of-15 test, because IRC 877(e)(2) removes any taxable year in which the individual was in fact treated as a resident of a treaty partner and did not waive treaty benefits. Every other year with a valid card counts, including a year in which you held the card for one day. The full counting mechanics, the worked example, and the residency start-date rules are in our green card abandonment guide.
The exclusion is written by facts and not by election, so it cuts in opposite directions depending on when the treaty residence actually began. A person whose treaty residence started in year 4 sheds those years and may never reach 8. A person whose first treaty year is year 9 already crossed the line, and the same filing that would have protected them earlier is now the event that terminates their status and starts the regime. That is the trap.
Immigration runs on a separate track. A tie-breaker claim is exactly the evidence USCIS uses to conclude that permanent residence has been abandoned, so a tax-motivated treaty position can cost the card itself.
What Should You Do If You Already Filed a Treaty Tie-Breaker Return?
Stop before the next return goes out and pin down the date. Once the expatriation date is fixed, IRC 877A(g)(1) makes you a covered expatriate if any one of three tests is met: $2,000,000 net worth on that date, average annual net U.S. income tax above $211,000 for 2026 ($206,000 for 2025), or failure to certify five years of tax compliance on Form 8854. Those three tests and the way they interact are covered in depth in our green card abandonment guide.
The third test usually decides a treaty case. Someone who has been filing nonresident treaty returns for years, unaware that the first of those years was their expatriation date, has never filed Form 8854 for that year. Non-filing makes them a covered expatriate automatically, whatever their net worth, and IRC 6039G(c) adds a $10,000 penalty unless the failure is due to reasonable cause and not willful neglect.
The certification also reaches back five years and requires clean prior filings, including FBAR filing under the Bank Secrecy Act & Form 8938 under FATCA. Our Form 8938 filing guide sets out the thresholds. A backlog in either one needs to be resolved before the certification can be signed truthfully.
How Much Exit Tax Does a Treaty-Triggered Expatriation Actually Cost?
Usually far less than a first pass suggests, because of a rule written for immigrants. Property you already owned on the day you first became a US resident gets a basis of at least its fair market value on that date under Section 877A(h)(2), so only post-arrival appreciation is marked. The election out of that rule is irrevocable, and it is the first thing to run before anyone quotes an exit tax number.
For a long-term resident who arrived owning a foreign home, a family business interest, or a portfolio built over a career abroad, the step-up can erase most of the deemed gain. Two limits apply. Notice 2009-85 Section 3.D says Treasury and the IRS intend to exercise their regulatory authority to exclude U.S. real property interests and property used in a U.S. trade or business, and the relevant date is the day you first became a U.S. resident under 7701(b). That is often an earlier substantial presence year, well before the card was issued. The Notice carves back in property used in a U.S. trade or business that isn't carried on through a permanent establishment, where you were previously a resident of a treaty country.
Only once the step-up is applied does the rest of the arithmetic matter. Worldwide property is treated as sold at fair market value the day before the expatriation date, the first $910,000 of net gain is excluded for 2026 ($890,000 for 2025) under Rev. Proc. 2025-32, and deferred compensation, IRAs, and non-grantor trust interests run through their own regimes outside that exclusion. Our Form 8854 and exit tax guide walks through that computation in full.
One escape route doesn't exist here. The dual-citizen-at-birth and young-expatriate exceptions in Section 877A(g)(1)(B) are keyed to relinquishing citizenship, so a green card holder who meets the net worth or income test has no statutory exception available. What is left is timing, and timing only works before the date is fixed. Our guide to pre-expatriation planning covers the review that belongs in that window.
