Montreal to Phoenix: Three Authorities, Aerospace, and Arizona's Flat 2.5%

Montreal's aerospace and semiconductor talent has a direct market in Phoenix's aerospace cluster and its chip fabs. The move is a large tax cut: Quebec's combined top rate of about 53.3% becomes about 39.5% in Arizona. The departure year runs through Revenu Québec, the CRA, and the IRS.

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.
• Arizona's flat 2.5%; no city income tax.
• Arizona follows the treaty's RRSP deferral.
• Quebec's 14.975% combined GST and QST becomes about 8.6% sales tax in Phoenix. 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. RAMQ ends when you leave Quebec to settle outside Canada. A Montreal condo kept and rented brings NR6 and Section 216 federally plus Quebec equivalents.

Phoenix's side

Arizona's flat 2.5% state income tax, the lowest flat rate of any state that taxes income; no city income tax anywhere in Arizona; sales tax about 8.6% in Phoenix and 7.8% to 8.3% in Scottsdale and the East Valley; property tax among the lowest in the US, near 0.6% effective; no estate tax.

The RRSP in Arizona

Federally deferred under Article XVIII of the treaty and deferred for Arizona because the state starts from federal AGI. Withdrawals face 25% Canadian withholding on lump sums, 15% on periodic RRIF payments within the treaty limit, a US foreign tax credit federally, and Arizona's 2.5%.

Who makes this move

Montreal aerospace engineers to Honeywell, Boeing Mesa, and the Phoenix aerospace cluster, Quebec semiconductor and process engineers to the Chandler and north Phoenix fabs, Montreal AI and software talent to Phoenix's tech employers, and Quebec retirees to the East Valley.

Worked example

A Montreal aerospace engineer moves to Chandler on July 31 with $180,000 of unrealized gain in a non-registered account, $350,000 in an RRSP, and a Longueuil home sold in the departure year.

• Departure tax. $180,000 gain, $90,000 taxable, at about 53.3%: roughly $48,000 across the T1 and TP-1.
• Home. Sold as a resident under the principal residence exemption on both returns.
• RRSP. No tax on departure; federal and Arizona deferral.
• Chandler. Combined top rate about 39.5%. Sales tax 14.975% becomes 7.8%.

"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

Montreal-to-Phoenix is a three-authority departure into a low-tax state. The US side is simple; the TP-1 departure date is the item that gets missed.
