Green Card Holder Tax Obligations Explained
Worldwide income until the card formally ends, living in Canada with a green card, and the tie-breaker risk
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
A green card holder — a lawful permanent resident — is a U.S. tax resident on worldwide income from the first day of residency until the status formally ends by surrender, revocation, or abandonment. Living in Canada doesn't end it. A green card holder in Canada files U.S. returns and FBARs, and may owe exit tax on surrender.

The rules
| Item | Treatment |
|---|---|
| Residency start | The first day present in the U.S. as a lawful permanent resident (or the first day of presence, if earlier, when you also meet the substantial presence test that year) |
| Residency end | Surrender (Form I-407), revocation, or abandonment determined administratively or judicially — residency then runs to December 31, or ends on the first day you are no longer a permanent resident if your tax home and closer connection are abroad for the rest of the year and you aren't a U.S. resident the next year |
| Living abroad | Still a U.S. tax resident — the card, not where you live, controls |
| Treaty tie-breaker | Can make a green card holder living in Canada a Canadian resident for income tax — but for a long-term resident (8 of the last 15 years) claiming it ends permanent-resident status for tax and is an expatriation (§7701(b)(6)); years it is claimed don't count toward the eight (§877(e)(2)) (the Form 8833 guide) |
| Reporting | FBAR, Form 8938, and the international forms as for any U.S. resident |
Canadians with green cards living in Canada
A Canadian who got a green card and moved back — or never fully moved — is a U.S. resident until they formally give it up (the green card abandonment guide). Each year they file a Form 1040 on worldwide income (crediting Canadian tax), or claim the treaty tie-breaker on Form 1040-NR with Form 8833 — which is an expatriation (Form 8854, possible exit tax) if they are already a long-term resident.
Frequently asked questions
Do green card holders pay U.S. tax if they live in Canada?
Yes — on worldwide income until the green card formally ends, with a credit for Canadian tax.
Does leaving the U.S. end my green card for tax?
No — only formal surrender, revocation, or a determination of abandonment ends it.
Can I use the treaty to be taxed only in Canada?
The tie-breaker can make you a Canadian resident for income tax, but if you've held the card in 8 of the last 15 years, claiming it is treated as an expatriation — Form 8854 and possibly the exit tax.
Do I file FBARs as a green card holder?
Yes, while you're a U.S. resident.
