Montreal to Pittsburgh: AI Jobs, Three Authorities, and Local Wage Tax

Montreal and Pittsburgh are two of North America's AI research centres, and researchers and engineers move between Mila and Carnegie Mellon's orbit constantly. Montreal's gaming and aerospace talent follows. The move is a large tax cut: Quebec's combined top rate of about 53.3% becomes about 43% inside Pittsburgh or about 41% in the suburbs. 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.
• Pennsylvania's flat 3.07% plus a 3% local earned income tax on Pittsburgh residents; suburbs charge about 1%.
• Pennsylvania exempts most retirement income after retirement age.
• Quebec's 14.975% combined GST and QST becomes 7% sales tax. 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.

Pittsburgh's side

Pennsylvania's flat 3.07% state income tax; a 3% local earned income tax on Pittsburgh residents (1% city plus 2% school district), with most suburbs charging 1%; 7% sales tax in Allegheny County; property tax among the higher effective rates in the US, near 2% in Allegheny County after recent reassessments; no estate tax, but Pennsylvania's inheritance tax applies at 4.5% to lineal heirs, 12% to siblings, and 15% to others, with a spousal exemption.

The RRSP in Pennsylvania

Federally deferred under Article XVIII of the treaty. Pennsylvania taxes eight classes of income rather than starting from federal AGI, and it does not tax the undistributed earnings of retirement plans, which supports deferral. Pennsylvania also exempts most retirement income received after retirement age, which can cover RRIF withdrawals; document the position in the first-year file. Canadian withholding is 25% on lump sums, 15% on periodic RRIF payments within the treaty limit, with a US foreign tax credit federally.

Who makes this move

Montreal AI researchers to Carnegie Mellon's orbit and Pittsburgh's AI companies, Quebec robotics and autonomous vehicle engineers to the city's AV firms, Montreal game developers to Pittsburgh's studios, and Quebec aerospace engineers to the region's manufacturers.

Worked example

A Montreal machine learning researcher moves to Pittsburgh on July 31 with $150,000 of unrealized gain in a non-registered account, $300,000 in an RRSP, startup shares deferred under T1244, and a Plateau condo sold in the departure year.

• Departure tax. $150,000 gain, $75,000 taxable, at about 53.3%: roughly $40,000 across the T1 and TP-1; startup shares deemed sold with tax deferred under T1244.
• Condo. Sold as a resident under the principal residence exemption on both returns.
• RRSP. Federally deferred; Pennsylvania position documented.
• Pittsburgh. State 3.07% plus 3% local. Combined top rate about 43%. Sales tax 14.975% becomes 7%.

"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 AI movers often hold shares in a Quebec startup without a liquidity event. Those shares are deemed sold on departure, and the valuation is the whole file. We get a defensible valuation before the date is set and file T1244 to defer the tax.
