Do I Still File US Taxes After Moving to Canada? Yes — Here Is What the Annual Package Actually Looks Like

The United States is nearly alone in taxing its citizens on worldwide income wherever they live, so the move to Canada changes your address, your bank, and your payroll — and leaves the 1040 exactly where it was. Green card holders are in the same position until the card is formally abandoned or a treaty position with an expatriation analysis is deliberately taken. What the move does change is the arithmetic and the attachments. Canadian tax rates are generally higher than US rates on the same income, so the foreign tax credit usually eliminates the US bill; the FEIE is an alternative for earned income. But the return grows: FBAR for the Canadian accounts, Form 8938 above its thresholds, Form 1116 credit computations, treaty positions for RRSPs and other registered plans, and — where the American owns a Canadian corporation, trust, or mutual funds — the heavyweight forms (5471, 3520, 8621). The practical reality for most Americans in Canada: little or no US tax owed, and a return that is more expensive to prepare than the one they left behind.

Key takeaways

• The obligation continues: US citizens and green card holders file the 1040 on worldwide income every year the filing thresholds are met, regardless of residence. Filing from abroad brings an automatic extension to June 15, with tax still due April 15.
• Double tax is prevented, not the filing: the foreign tax credit (Form 1116) credits Canadian income tax against US tax on the same income; because Canadian rates usually exceed US rates, most Americans in Canada owe zero or near-zero US tax and build credit carryovers. The foreign earned income exclusion is the alternative for wages and self-employment income.
• The information forms are where the risk lives: FBAR (Canadian accounts over $10,000 aggregate), Form 8938, Form 8621 for Canadian mutual funds and ETFs (PFICs), Form 5471 for a Canadian corporation, Forms 3520/3520-A where a trust is involved. Penalties attach to the forms, not the tax.
• Registered accounts have US personalities: RRSPs enjoy treaty deferral; TFSAs, RESPs, and FHSAs do not shelter income from the US and need case-by-case handling.
• State tax may not let go: a state return can continue until domicile is properly broken — a separate project from the federal one.
• What stops the cycle: only renouncing citizenship (or properly abandoning the green card), each with an exit-tax analysis. Short of that, the annual package is permanent.

What a typical year looks like

A salaried American in Toronto files: the Canadian T1 first (Canada has first taxing rights on Canadian employment income), then the 1040 claiming foreign tax credits for the Canadian tax, FBAR, and 8938 if thresholds are met. Owing: usually nothing, or small amounts on US-source income and on items Canada taxes lightly but the US taxes fully. The failure mode is never the tax — it is the American who filed nothing for six years because "I pay tax in Canada," and now needs the streamlined procedures to catch up before the penalties conversation starts.

The design rules that keep it cheap

Hold US-listed ETFs instead of Canadian mutual funds (no PFICs). Think twice before incorporating in Canada without cross-border advice (a CFC brings Form 5471 and GILTI). Use the RRSP freely; treat the TFSA as a taxable account for US purposes and keep only simple holdings in it, or skip it. Keep the account count manageable — every account is an FBAR line. The American in Canada whose affairs were designed for the dual system files two clean returns a year; the one whose affairs grew organically files two returns and five information forms.

Worked example

An engineer moves from Austin to Vancouver in March, earning C$160,000 at a BC employer, with a US brokerage account and a new Canadian chequing account and RRSP. Year one: part-year Canadian T1 reporting world income from March; full-year 1040 reporting everything, with Form 1116 crediting BC/federal Canadian tax against US tax on the Canadian wages — US federal tax on the wages nets to zero, and Texas never had a state tax to break. FBAR: yes (Canadian accounts crossed $10,000). 8938: measured against the higher living-abroad thresholds. RRSP: treaty deferral, no annual US tax on growth. His one design decision that year: his Canadian advisor proposed a TFSA full of Canadian equity funds; he opened the TFSA but filled it with a single US-listed ETF, keeping the account US-taxable but PFIC-free. Total US tax: $0. Total forms: two returns, one FBAR, one 8938 — the steady state he will repeat every year he lives in Canada.

"If you are a U.S. citizen or resident alien, the rules for filing income, estate, and gift tax returns and paying estimated tax are generally the same whether you are in the United States or abroad." — Internal Revenue Service, U.S. citizens and resident aliens abroad, https://www.irs.gov/individuals/international-taxpayers/us-citizens-and-resident-aliens-abroad

The CRA states that you become a resident "when you establish significant residential ties in Canada," report world income from that date, and are "considered to have sold the property and to have immediately reacquired it at a cost equal to the fair market value (FMV) on the date that you became a resident of Canada." — Canada Revenue Agency, Newcomers to Canada, https://www.canada.ca/en/revenue-agency/services/tax/international-non-residents/individuals-leaving-entering-canada-non-residents/newcomers-canada-immigrants.html

Practitioner note

The question is always asked hoping the answer is no, and the answer has been yes since the Civil War. The reframe that helps: for an American in Canada, US filing is a compliance cost, not usually a tax cost — and the size of that compliance cost is a design choice made by what you own. We spend the first meeting with every new arrival on the ownership design, because the returns then write themselves for a decade.
