Moving From Quebec to New York: What Happens to Your Taxes?

Montreal to New York is one of the busiest francophone-to-US corridors there is, and it isn’t a move from a high-tax place to a low-tax one. Quebec’s combined top marginal rate runs about 53.31%. New York’s runs about 51% inside New York City and closer to 45% upstate. Both sides tax hard; what changes is which government is doing it, and how many of them are doing it at once in the year you move.

Why is Montreal to New York such a common corridor?

Finance is the biggest single lane. Montreal’s asset management and banking talent feeds Wall Street directly, and the francophone base makes New York an easy landing spot compared to other US cities. Tech is close behind: Montreal’s AI and gaming ecosystem, Ubisoft, the Mila research cluster, and the talent that came out of Element AI, sits a short flight from NYC’s own AI and gaming studios. The UN and the cluster of international organizations headquartered in New York draw francophone professionals for a third reason entirely, diplomatic and multilateral work that barely exists anywhere else in the US.

• Housing is the tradeoff underneath all three: Montreal is genuinely affordable by North American standards, and NYC is not, so the compensation bump has to clear a real cost-of-living gap before it’s a win on paper.

How do Quebec and New York tax rates actually compare?

Both are high-tax jurisdictions, but the shape is different. Quebec’s provincial bracket alone tops out at 25.75% on income over roughly $126,000, stacked on top of federal tax net of the Quebec abatement. New York’s state rate tops out at about 9.65%, and New York City adds its own income tax on top of that for city residents, roughly 3.876% at the top bracket. Combined state-plus-city lands around 13.5%, well under Quebec’s provincial-plus-federal load.

	Quebec	New York (state + NYC)
Top provincial/state rate	25.75%	9.65% state
City/local add-on	None	~3.876% (NYC residents only)
Combined top marginal rate	~53.31%	~51% in NYC, ~45% upstate
Consumption tax	QST 9.975% + GST 5% (~15% combined)	NYC sales tax ~8.875%
Separate tax authority	Yes, Revenu Québec	No, NY runs through the same IRS-adjacent state system as any other state

The headline rates land close, but the sales tax picture flips hard. Quebec’s combined QST and GST run near 15% on most purchases. NYC sales tax is about 8.875%. That’s real money on everyday spending, in the other direction from the income tax comparison.

Which side wins on everyday cost of living?

Neither, cleanly. The income tax comparison and the sales tax comparison point opposite directions, and housing overrides both. A Plateau or Mile End apartment that rents for a modest sum by North American standards has no real Brooklyn or Manhattan equivalent at the same price, and that gap tends to dwarf the tax-rate differences on a monthly budget. This corridor is a lateral move between two high-tax, high-cost places, not an escape from either, and the real financial case for the move usually rests on compensation and career path rather than on any tax saving.

What returns do I file in the year I move?

Three authorities in Canada and the US, and a fourth if New York City is involved. The federal T1 goes to the CRA. The TP-1 goes to Revenu Québec, on its own schedules, using Relevé slips instead of T4s and T5s. The IRS gets a US return, either dual-status or full-year under the first-year election. New York State gets its own part-year resident return, and if you land inside the five boroughs, New York City’s tax rides on the same state return rather than a separate filing.

• The Toronto to New York guide works through the state and city residency tests in detail; those tests apply the same way regardless of which province you’re leaving.
• Combined federal and Quebec tax on the same income year can push you toward the limits of what the US foreign tax credit absorbs in a single year, since Quebec’s rate stacks on top of the federal one. The foreign tax credit limitation and carryover guide covers what happens to the excess when that limit is hit, and it’s worth checking before you assume the whole Canadian tax bill washes out against the US return.

Does Quebec’s departure tax work the same way here?

Yes. The federal deemed disposition under ITA 128.1(4) applies on your Quebec-to-US move exactly as it would for any other province, and the gain shows up on both the T1 and the TP-1. What’s different is the rate the gain gets taxed at on the Quebec side, since Quebec’s own brackets apply to the Quebec-source portion of that gain. The departure tax forms guide covers the T1161 and T1243 mechanics that apply here without modification.

What happens to my RRSP and my RRQ payments?

Your RRSP keeps working the way it would for anyone leaving Canada for the US. New York follows the federal treaty treatment: no state-level addback of untaxed RRSP growth, unlike a state such as California that has decoupled from the treaty on this point. The RRSP and TFSA moving-to-the-US guide covers withdrawal mechanics and Part XIII withholding.

• The RRQ, Quebec’s version of CPP, keeps paying from Quebec after you move, on the same schedule as if you’d stayed. The US-Canada treaty treats RRQ payments the same way it treats CPP for a US resident: taxable only in the US once you’re a US resident, reported and credited the same way. The CPP and OAS taxation guide covers the mechanics; RRQ rides the same treaty article as CPP.

Does New York’s estate tax reach a Quebec estate too?

It can, and it’s worth knowing about before it matters. New York has an estate tax cliff: cross about $6.94 million in a New York estate and the state’s 105% rule can claw back the entire exemption rather than just taxing the excess, which is a much harsher mechanic than the federal estate tax’s marginal structure. That sits alongside Quebec’s own succession rules, which don’t impose a separate provincial estate tax the way New York does at the state level, since Canada taxes death through deemed disposition rather than an estate tax.

• The US estate tax for Canadians guide covers the federal exposure a Canadian can face; New York’s cliff is a separate, additional layer on top of that for anyone domiciled in the state at death.

What should I do next?

Start with the Quebec side, since it has to close out before the US side can be built correctly. Get your Relevé slips, file the final TP-1 alongside the T1, and run the departure tax on anything appreciated. Then work the New York side: confirm state and city residency using the day-count and domicile tests, and decide between a dual-status and full-year US election before you file.
