Green Card Holder Living in Canada: Tax Obligations

A US green card holder who moves to Canada has the same US filing obligations as a US citizen: worldwide income is reported on a 1040 every year, regardless of where you live. The green card makes you a US resident alien under IRC 7701(b)(1)(A)(i), and that status does not end when you cross the border. Meanwhile, once you settle in Canada, the CRA treats you as a Canadian resident under ITA 250 and taxes your worldwide income from that date forward. You file two returns, you claim foreign tax credits on each to prevent double taxation, and you pick up the same FBAR and Form 8938 reporting obligations as any other US person with foreign accounts.

What are the US filing obligations?

The green card creates a worldwide filing obligation identical to that of a US citizen:

• Form 1040 on worldwide income, every year, regardless of where you live or how much you earn. The automatic 2-month extension to June 15 applies to US persons living abroad (including green card holders), but interest runs from April 15.
• FBAR (FinCEN 114) if the aggregate value of your foreign financial accounts exceeds $10,000 at any point during the year. Every Canadian bank account, brokerage account, RRSP, TFSA, and RESP counts.
• Form 8938 if your specified foreign financial assets exceed the reporting thresholds ($200,000 at year-end or $300,000 at any point during the year for Americans abroad filing single; higher for married filing jointly).
• Form 3520/3520-A if you are a beneficiary of a foreign trust. The TFSA is the most common trigger.
• Form 8621 if you hold PFICs (Canadian mutual funds and Canadian-listed ETFs outside the RRSP).

The foreign tax credit on Form 1116 offsets US tax with Canadian tax paid. Because Canadian rates are generally higher, the credit typically eliminates the US tax on Canadian-source income, and the excess credits carry forward for up to ten years.

How does the treaty tiebreaker work for green card holders?

The treaty tiebreaker under Article IV resolves dual residency by looking at permanent home, centre of vital interests, habitual abode, and nationality, in that order. For a green card holder living in Canada with family and employment in Canada, the tiebreaker assigns treaty residence to Canada at step 1 or 2 (permanent home in Canada, centre of vital interests in Canada).

• Nationality test (step 4). A Canadian citizen with a US green card (but not US citizenship) would be assigned to Canada. This test rarely matters because the earlier tests usually resolve the issue.
• Effect on taxing rights. Canada, as the treaty resident country, gets to tax your worldwide income first, and the US gives a credit for Canadian tax paid. To claim this treaty position on your US return, file Form 8833 disclosing the treaty-based return position.

Can a green card holder claim the FEIE?

Yes, but only through the physical presence test (330 full days in a foreign country during a consecutive 12-month period). The bona fide residence test is available only to US citizens under IRC 911(d)(1), not to resident aliens.

For a green card holder living full-time in Canada, the 330-day test is typically met as long as trips back to the US total fewer than 35 days in the 12-month period. But the FEIE vs foreign tax credit analysis almost always favors the FTC for anyone living in Canada, because Canadian rates exceed US rates and the FTC produces a larger benefit.

What happens to Canadian accounts?

The RRSP, TFSA, RESP, and Canadian bank accounts all require US reporting:

• RRSP. The RRSP is tax-deferred in Canada. On the US side, the treaty election under Article XVIII(7) defers US tax on the growth inside the account. Without the election, the IRS taxes the annual income inside the RRSP as current income, even though no withdrawal occurred. The RRSP contribution guide covers the mechanics.
• TFSA. The TFSA is tax-free in Canada but not recognized by the IRS. The likely classification is a foreign trust, requiring Forms 3520 and 3520-A annually. The compliance cost usually exceeds the benefit.
• RESP. The RESP for your children’s education has similar foreign trust issues, though the analysis is more complex. Many cross-border preparers recommend avoiding the RESP if you are a US person.
• Canadian mutual funds and ETFs. Any Canadian-domiciled fund held outside the RRSP is almost certainly a PFIC. Hold US-listed ETFs in your non-registered accounts and keep Canadian-listed investments inside the RRSP where the treaty election shelters them.

What happens if I abandon the green card?

If you decide to give up the green card, you must formally surrender it by filing Form I-407 with USCIS. The tax consequences depend on whether you are a “long-term resident” under IRC 877A:

• Long-term resident (8 or more of the last 15 years with a green card): abandoning triggers the exit tax (same rules as renouncing US citizenship). You are deemed to have sold all your assets at fair market value the day before expatriation, with an exclusion of $886,000 (2024, indexed). Gains above the exclusion are taxed, and deferred compensation and retirement accounts have their own rules.
• Not a long-term resident (fewer than 8 of the last 15 years): no exit tax applies. You file a final 1040 for the year of abandonment and then stop filing US returns (unless you have US-source income).

Do I owe tax in both countries every year?

You report income to both countries, but the foreign tax credit prevents full double taxation. The practical result is that you pay roughly the same total tax as a Canadian-only resident (because Canadian rates are generally higher, and the FTC wipes out most of the US tax). The extra cost is compliance: two returns, information forms, and the professional fees to prepare them.

• Rate comparison. The Canada vs US tax rates comparison shows the effective rates by bracket. On employment income, the combined Canadian rate exceeds the US federal rate at nearly every income level, so the FTC eliminates the US tax and produces excess credits that carry forward.
• Exceptions. The US rate can exceed the Canadian rate on specific types of income (US-source capital gains in certain brackets, PFIC income, NIIT), and those gaps can create a residual US tax even when the overall Canadian rate is higher.

What should I do next?

If you are a green card holder living in Canada and have not been filing US returns, the first step is understanding your exposure and the available remedies (the streamlined program is usually the right path). If you are already filing, the focus is on optimizing the FTC, making the RRSP treaty election, and avoiding the PFIC and TFSA traps.

• Treaty tiebreaker rules for dual residents
• Form 1116 and the foreign tax credit
• FEIE vs foreign tax credit for Canada
• Streamlined filing for green card holders
• RRSP contributions for US citizens
• TFSA as a foreign trust
• Exit tax on giving up the green card
