Quebec to New York: Three Tax Authorities on the Way Out, Two More on the Way In

Montreal to New York is nearly tax-neutral on income. Quebec's combined top rate is about 53.3%; a Manhattan resident's combined federal, state, and city rate is about 51%. What the corridor carries instead is complexity: the departure year runs through Revenu Québec, the CRA, and the IRS, and then New York State and New York City each apply their own residency rules.

Key takeaways

• Two Canadian departure returns: the federal T1 and Revenu Québec's TP-1, with matching departure dates.
• Quebec's roughly 53.3% top rate sets the departure tax. On a $300,000 unrealized gain, about $80,000.
• New York State's practical top rate is 9.65% and New York City adds up to 3.876%; combined with federal, about 51% in the city.
• New York's estate tax exemption is about $7.35 million with a cliff.
• Quebec's 14.975% combined GST and QST becomes 8.875% sales tax in the city. RAMQ ends on departure.

The three-authority departure

The federal deemed disposition applies to non-registered investments, private company shares, crypto, and property outside Canada; Quebec mirrors it. Report on federal Form T1243 (with T1161 if the property list exceeds $25,000) and on the Quebec equivalents. Because New York taxes capital gains as ordinary income, realizing gains before departure at Quebec's half inclusion is cheaper than realizing them later. RAMQ ends when you leave Quebec to settle outside Canada.

New York's side

State brackets from 4% to 10.9% (the top rate only above $25 million); New York City resident tax from 3.078% to 3.876%; capital gains at ordinary rates; statutory residency at 183 days plus a permanent place of abode, with aggressive audits; 8.875% sales tax in the city; estate tax with an exemption near $7.35 million and a cliff at 105%.

The RRSP in New York

Federally deferred under Article XVIII of the treaty. New York has historically declined to follow federal treaty exclusions in some contexts; whether RRSP growth must be added back on the New York return is a position to take with the guidance in hand. If it must, restructure or draw down before departure while still a Quebec resident.

Who makes this move

Montreal finance professionals to Wall Street, Quebec lawyers to New York offices, francophone policy professionals to the UN and international organizations, and Montreal tech workers to the city's engineering hubs.

Worked example

A Montreal investment banker moves to Manhattan on July 1 with $300,000 of unrealized gain in a non-registered account, $600,000 in an RRSP, and a Westmount home sold in the departure year.

• Departure tax. $300,000 gain, $150,000 taxable, at about 53.3%: roughly $80,000 across the T1 and TP-1.
• Home. Sold as a resident under the principal residence exemption on both returns.
• RRSP. Federally deferred; New York position documented.
• New York. Combined top rate about 51%, a small cut from Quebec. Sales tax 14.975% becomes 8.875%.

"When you leave Canada, you are considered to have sold certain types of property (even if you have not sold them) at their fair market value (FMV) and to have immediately reacquired them for the same amount. This is called a deemed disposition and you may have to report a capital gain (also known as departure tax)." — Canada Revenue Agency, Leaving Canada (emigrants), https://www.canada.ca/en/revenue-agency/services/tax/international-non-residents/individuals-leaving-entering-canada-non-residents/leaving-canada-emigrants.html

Practitioner note

Quebec-to-New York files are five-authority files: Revenu Québec, the CRA, the IRS, New York State, and New York City. Each has its own residency start, and they do not have to agree. We reconcile all five dates in one memo before the first return is filed.
