Giving Up a Green Card to Move Back to Canada: The Eight-Year Rule, the Exit Tax Tests, and Form 8854 for Long-Term Residents

Short version: Green Card Abandonment and the Exit Tax

The green card holder heading home assumes the card is an immigration document that simply lapses; the tax code treats surrendering it, for a long-term holder, as leaving the United States permanently in the same sense a renouncing citizen does. The eight-year rule: a lawful permanent resident who has held that status in at least eight of the fifteen tax years ending with the year of expatriation is a "long-term resident," and a long-term resident who ceases to be a lawful permanent resident — by formally abandoning the card (Form I-407), by having it revoked or administratively determined abandoned, or by taking a treaty position to be treated as a resident of another country — is treated as expatriating, subject to the exit-tax regime; a green card holder with fewer than eight years in the fifteen-year window is not a long-term resident and can abandon the card with no exit tax, no Form 8854, and no covered-expatriate consequences — the single most valuable planning fact in this area, because the eighth year is a threshold the holder crosses by simply keeping the card. Counting the years: any part of a tax year in which the individual held the card counts as a full year (a card obtained in December counts that year; a card abandoned in January counts that year), so the eight-of-fifteen test is reached faster than intuition suggests — a holder who received the card in late year one and is contemplating abandonment in year eight has already met it; and years in which the holder took a treaty tie-breaker position to be treated as a nonresident of the US are excluded from the count (a green card holder in Canada who filed as a treaty nonresident for three years has three years that don't count — but taking that position may itself have been an expatriating act, discussed below). The covered-expatriate tests, applied to a long-term resident who expatriates: the net worth test (US$2 million or more on the expatriation date, a figure that is not indexed), the tax liability test (average annual net US income tax over the five prior years above the indexed threshold — US$211,000 for a 2026 expatriation), and the certification test (failure to certify on Form 8854 that all US tax obligations for the five prior years have been met — the test that catches the non-compliant regardless of wealth); meeting any one makes the individual a covered expatriate, subject to the mark-to-market exit tax — a deemed sale of worldwide assets on the day before expatriation, with gain above the indexed exclusion amount taxed (and with special rules for deferred compensation, specified tax-deferred accounts including IRAs, and interests in nongrantor trusts, which are taxed on their own regimes rather than marked to market) — and to the section 2801 tax on US persons who later receive gifts or bequests from them (the covered-expatriate-gift guide). The treaty-position trap: a green card holder living in Canada who takes the treaty tie-breaker position to be treated as a Canadian resident (filing a 1040-NR with Form 8833) is, if a long-term resident, treated as having expatriated on the date the position is taken — the tie-breaker filing is itself the expatriating act, triggering the exit-tax regime and Form 8854 for that year whether or not the holder intended to give up the card or understood the consequence; a green card holder short of eight years can take the position without expatriation consequences (though the position may jeopardize the card under immigration law, which treats a claim of foreign residence as evidence of abandonment). The sequence for a clean exit by a long-term resident who is not (or need not be) a covered expatriate: bring the five prior years fully into compliance (the certification test — every return, every FBAR, every information return; the streamlined guides if not); compute net worth on the planned date against US$2 million (with planning where the holder is near the line — gifts before expatriation, valuation, the timing of the date); compute the five-year average tax liability against the threshold; choose the expatriation date and abandon formally (Form I-407 at a consulate, with the date of abandonment fixed by the filing); file the final dual-status return for the expatriation year with Form 8854 attached (the certification, the balance sheet, the income statement, and the covered-expatriate determination), and mail a copy of Form 8854 to the IRS's designated address; and, for a covered expatriate, compute the mark-to-market tax with the exclusion, elect deferral with security where cash is a problem, and plan the specified accounts (the IRA's treatment as a deemed distribution at the expatriation date, taxed without the early-distribution penalty, unless the treaty and the regulations' elections provide otherwise). The alternative — keeping the card while living in Canada — is its own guide (the green-card-holder guide): worldwide US filing continues, the treaty tie-breaker is unavailable without expatriating, and immigration law requires maintaining US residence in fact, which the Canadian resident isn't doing. The planning fact that reorders everything: a holder in year six or seven who intends to return to Canada should abandon the card before the eighth year begins, exiting the regime entirely — the difference between a Form I-407 and nothing, and a Form I-407 plus Form 8854 plus a deemed sale of everything they own.

Key takeaways

• Eight of fifteen years makes a long-term resident: any part of a year counts; the eighth year is reached by keeping the card — abandoning before it begins exits the regime completely.
• Long-term residents who abandon expatriate: the same regime as renouncing citizens — the covered-expatriate tests (US$2 million net worth, the five-year average tax liability, the five-year compliance certification), the mark-to-market exit tax above the exclusion, and Form 8854.
• The treaty tie-breaker is an expatriating act for long-term residents: filing as a Canadian resident under the treaty triggers expatriation on the filing date — intended or not.
• The certification test catches the non-compliant regardless of wealth: five clean years are the price of a non-covered exit — catch up first (the streamlined guides), then expatriate.
• The sequence: compliance, the net worth and liability tests with planning near the lines, formal abandonment (Form I-407) on a chosen date, the final dual-status return with Form 8854, and the specified-account treatment for IRAs.
• The year-six question: a holder planning to return to Canada should decide before the eighth year — the decision that turns a deemed sale of everything into a consular form.

The green card exit review

Count the years (any part of a year counts; treaty-nonresident years excluded). Under eight: abandon freely — Form I-407, no 8854, no exit tax; if the eighth year is near and a return to Canada is planned, abandon now. Eight or more: run the three tests; fix compliance for the five prior years; plan around the net worth line where close; choose the date; abandon formally; file the expatriation-year return with Form 8854; handle the IRA and any deferred compensation under the specified-account rules; and never take a treaty tie-breaker position without understanding it is the expatriation. An afternoon for the count, a season for the exit.

Worked example

A Calgary engineer has held a green card for seven tax years (obtained in November of year one — which counts as a full year) and plans to return to Canada next spring. The count: seven years through this year; next year — the year of the planned return — would be the eighth, making him a long-term resident on abandonment. His net worth is about US$2.6 million (a Calgary condo kept and appreciated, a US brokerage account, a 401(k)); the tests would make him a covered expatriate. The plan: abandon the card this December (Form I-407 at the consulate), before the eighth year begins — no long-term resident status, no expatriation, no Form 8854, no deemed sale; his final US return is a dual-status return for this year (resident through the abandonment date, nonresident after), and his return to Canada proceeds under the re-entry guides. Cost of the December abandonment against his original spring plan: a few months without the card he wasn't going to use, and a US$2.6 million mark-to-market exposure avoided. His colleague, who held her card nine years in Boston before moving back to Toronto and, on her first Canadian-resident year, filed a 1040-NR with a treaty tie-breaker position to Canada on her US preparer's advice: the filing expatriated her on its date — a long-term resident, net worth above the line, a covered expatriate with a deemed sale of her worldwide assets (including the Toronto house she'd bought) computed as of the day before the filing, Form 8854 required for a year she didn't know was her expatriation year, and a section 2801 shadow over any future gifts to her US-citizen nephew. The repair engagement runs for two years. The difference between them was a count nobody did.

The IRS explains that under the mark-to-market regime "all property of a covered expatriate is deemed sold for its fair market value on the day before the expatriation date," and that an individual is a covered expatriate if, among the tests, "your net worth is $2 million or more on the date of your expatriation." — Internal Revenue Service, Expatriation Tax, https://www.irs.gov/individuals/international-taxpayers/expatriation-tax

The IRS explains that "expatriation tax provisions apply to U.S. citizens who have relinquished their citizenship and long-term residents who have ended their residency (expatriated)," and that "Form 8854 is used by individuals who have expatriated on or after June 4, 2004." — Internal Revenue Service, About Form 8854, https://www.irs.gov/forms-pubs/about-form-8854

Practitioner note

The green card exit turns on a count most holders have never done: eight of fifteen years, any part of a year counting, with the treaty tie-breaker filing as an expatriating act the holder's own preparer can trigger. Our exit review counts first — and for the year-six-or-seven holder planning a return to Canada, the advice is to abandon before the eighth year and exit the regime entirely; for the long-term resident, it is five clean years, the tests run with planning near the lines, a chosen date, and Form 8854 filed with the final return.
