Montreal to Philadelphia: Pharma, Three Authorities, and the City Wage Tax

Philadelphia's life sciences corridor, its fintech and finance employers, and its defence contractors recruit Montreal's pharma researchers, AI engineers, and aerospace staff. The move is a large tax cut: Quebec's combined top rate of about 53.3% becomes about 43.8% inside Philadelphia 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 Philadelphia's roughly 3.74% resident wage tax; suburbs charge about 1%.
• Pennsylvania exempts most retirement income after retirement age.
• Quebec's 14.975% combined GST and QST becomes 8% sales tax in Philadelphia. 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.

Philadelphia's side

Pennsylvania's flat 3.07% state income tax; Philadelphia's Wage Tax of about 3.74% on residents (about 3.43% on non-residents who work in the city), which most suburbs replace with a 1% local earned income tax; 8% sales tax in Philadelphia (6% state plus 2% city), 6% in most suburbs; property tax near 1.4% effective; 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 pharma and biotech researchers to the Philadelphia life sciences corridor, Quebec AI and software engineers to Philadelphia's fintech and enterprise employers, Montreal aerospace engineers to the region's defence contractors, and Quebec academics to Penn and the city's universities.

Worked example

A Montreal pharma researcher moves to King of Prussia on July 31 with $180,000 of unrealized gain in a non-registered account, $350,000 in an RRSP, and a Rosemont condo 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.
• Condo. Sold as a resident under the principal residence exemption on both returns.
• RRSP. Federally deferred; Pennsylvania position documented.
• King of Prussia. State 3.07% plus 1% local; no city wage tax. Sales tax 14.975% becomes 6%.

"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-Philadelphia files are four-authority departure years (Revenu Québec, CRA, IRS, Pennsylvania) plus a local earned income tax return. We reconcile the departure date across all of them before the first return is filed.
