Montreal to Tampa: Three Tax Authorities and a Corporate Corridor

Tampa's draw for Montrealers is corporate: financial services operations, healthcare systems, cybersecurity and defence contractors near MacDill, and a tech scene that recruits from Montreal's AI and software base. The tax cut is among the largest available (Quebec's combined top rate is about 53.3%; Florida's state income tax is zero), and the departure year is among the most paperwork-heavy, because Revenu Québec administers its own income tax and expects its own final return.

Key takeaways

• Two Canadian departure returns: the federal T1 and Revenu Québec's TP-1, with matching departure dates.
• Departure tax at about 53.3% combined. On a $300,000 unrealized gain, roughly $80,000.
• Quebec's 14.975% combined GST and QST becomes 7.5% sales tax in Hillsborough County.
• RAMQ ends on departure; QPP is taxed only in the US once you are a Florida resident.
• Tampa has no city income tax; Florida has no state income tax.

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 for the property list if it exceeds $25,000) and on the Quebec equivalents. The 16.5% Quebec abatement is built into the 53.3% combined rate.

The US side starts the same year: a dual-status first return, the RRSP treaty position, FBAR on remaining Canadian accounts, and Form 8938.

Montreal-specific items

• RAMQ. Ends when you leave Quebec to settle outside Canada. Corporate relocations usually carry day-one US coverage; confirm the dates.
• QPP. Taxable only in the US under Article XVIII of the treaty.
• Montreal property. Not caught by departure tax. Renting it means NR6 and Section 216 federally plus Quebec equivalents; selling later means Section 116 clearance.
• Corporations. A Montreal professional or consulting corporation loses CCPC status on departure, becomes a US controlled foreign corporation, and needs a Quebec corporate return closed as well as a federal one.

Tampa's side

No state income tax, no city income tax, no estate tax. Sales tax is 7.5% in Hillsborough County (7% in Pinellas). Property tax is higher than Montreal's on a like-for-like home; homestead (own and occupy as your permanent residence on January 1, apply by March 1) takes up to $50,000 off assessed value and caps annual increases at 3%. Documentary stamp tax on a purchase deed is 0.7%.

The RRSP stays tax-deferred in the US under the treaty, with no Florida layer to disregard it. Withdrawals face 25% Canadian withholding on lump sums, 15% on periodic RRIF payments within the treaty limit, with a US foreign tax credit.

Worked example

A Montreal financial services manager relocating with a Tampa employer leaves on June 30 with $260,000 of unrealized gain in a non-registered account, $600,000 in RRSPs, and a Longueuil home sold in the departure year.

• Departure tax. $260,000 gain, $130,000 taxable, at about 53.3%: roughly $69,000 across the T1 and TP-1.
• Home. Sold as a resident under the principal residence exemption on both returns.
• RRSP. No tax on departure; periodic withdrawals later at 15%.
• Tampa. No state or city income tax. Sales tax 14.975% becomes 7.5%.

Official sources

"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

Revenu Québec sets out the income tax obligations of individuals who cease to be resident in Québec, including the deemed disposition of property on departure. — Revenu Québec, Leaving Québec, https://www.revenuquebec.ca/en/citizens/your-situation/residence-status-and-tax-obligations/leaving-quebec/

"No tax upon estates or inheritances or upon the income of natural persons who are residents or citizens of the state shall be levied by the state, or under its authority." — Florida Constitution, Article VII, Section 5(a), http://www.leg.state.fl.us/statutes/index.cfm?submenu=3#A7S05

Practitioner note

Corporate relocation packages from Tampa employers frequently include tax equalization, which keeps the employee whole for the move year. Equalization settlements are themselves taxable, arrive a year late, and are computed by a preparer who may not know Quebec exists. We reconcile the equalization calculation against the actual T1, TP-1, and US return so the client is not paying tax on Quebec income twice.
