Moving from the US to Quebec: What Changes on Your Taxes, and What Follows You

Quebec is the one province where a US arrival files three income tax returns: the federal T1, Revenu Québec's TP-1, and the US 1040. Montreal's AI, aerospace, gaming, and university sectors draw Americans in numbers, and the province's combined top marginal rate of about 53.3% and 14.975% combined sales tax are the price. The US filings follow you regardless, and in Quebec they have to be reconciled to two Canadian returns rather than one.

Key takeaways

• No arrival tax. Property is deemed acquired at fair market value when you become a Canadian resident; US basis is unchanged.
• Quebec's top provincial bracket is 25.75%, for a combined top rate of about 53.3% after the 16.5% federal abatement.
• 14.975% combined GST and QST.
• RAMQ coverage generally begins after a waiting period of up to three months.
• The foreign tax credit on the 1040 must combine federal and Quebec tax, and Quebec's return is in French.

Becoming a Quebec resident

Residency starts when you establish residential ties. From that date Canada and Quebec tax worldwide income, and under section 128.1 of the federal Act (mirrored in Quebec's Taxation Act) most property is deemed acquired at fair market value on arrival. Your US basis stays where it was.

Quebec specifics:

• Two Canadian returns. Federal T1 and Quebec TP-1, each with its own deductions, credits, and instalment system.
• Provincial tax. Brackets top out at 25.75%. The federal abatement of 16.5% of basic federal tax applies to Quebec residents.
• QPP, not CPP. Quebec runs its own pension plan; contributions come off Quebec-source employment.
• Sales tax. 5% GST plus 9.975% QST.
• RAMQ. Register on arrival; coverage generally begins after a waiting period of up to three months, with exceptions for some work-permit holders and their families under reciprocal agreements.
• Property. Welcome tax (land transfer duty) on purchase, graduated by price; Montreal adds higher brackets at the top.

What follows you from the US

• Annual 1040 with Form 1116 foreign tax credits; Quebec's combined rate covers the US liability on employment income. The credit is computed on federal plus Quebec tax, so the TP-1 has to be finished before the 1040.
• FBAR and Form 8938 on Canadian accounts above thresholds.
• PFIC. Canadian mutual funds and Canadian-listed ETFs each require Form 8621. Hold US-listed ETFs instead.
• TFSA. Taxable in the US and potentially a foreign trust. Skip it.
• RRSP. Deduction on both Canadian returns, US deferral under the treaty.
• Roth IRA. Article XVIII(7) election on the first Canadian return; no contributions after arrival.
• 401(k) and IRA. Stay in the US; taxable on both Canadian returns on withdrawal with foreign tax credits.
• T1135 once non-Canadian property exceeds $100,000 CAD in cost (arrival year exempt).

Who moves to Quebec

AI researchers and engineers into Montreal's labs and startups, aerospace engineers, gaming developers, academics into McGill and Université de Montréal, and Americans with Quebec partners. Work-permit holders should check whether their home country or state has a health-coverage reciprocal agreement with Quebec that shortens the RAMQ wait.

Worked example

An American AI researcher moves from New York to Montreal on August 15 with $300,000 in a US brokerage account (US basis $200,000), $250,000 in a 401(k), and RSUs from a US employer continuing to vest.

• Arrival. Brokerage deemed acquired at $300,000 for Canadian and Quebec purposes; US basis stays at $200,000.
• RSUs. Vests after arrival are split by working days; the Canadian portion is taxed on the T1 and TP-1, with a foreign tax credit on the 1040.
• 401(k). Left in place.
• New York exit. Part-year New York State and City returns; close residency formally.
• Reporting. FBAR and Form 8938 on new Canadian accounts; no TFSA, no Canadian mutual funds.

Practitioner note

The Quebec file's order of operations matters: the TP-1 and T1 must both be complete before the Form 1116 foreign tax credit can be computed, because the credit is on the combined tax. A US preparer who only sees the T1 understates the credit and overstates the US bill. We prepare all three returns together.
