Moving From Quebec to Florida: What Happens to Your Taxes?

Quebec residents give up the highest combined marginal rate in Canada, roughly 53.31%, for Florida’s zero. That is the single biggest rate drop of any provincial corridor, and it comes with a wrinkle no other province carries: Quebec runs its own tax authority, so leaving means closing out with two governments instead of one, on two separate returns, before Florida even enters the picture.

Why does leaving Quebec cost more than other provinces?

Quebec’s top provincial bracket is 25.75%, and combined with federal tax the top marginal rate on ordinary income lands around 53.31%, the highest of any province. Ontario and British Columbia sit closer to 20.5% provincially, Alberta charges a flat 15%, and Florida charges nothing at all. The departure tax, a deemed sale of most capital property on the date Canadian residency ends, gets taxed at whatever bracket the resulting gain lands in, so a Quebec filer with meaningful unrealized gains is paying that departure tax at the country’s steepest rate on the way out the door.

Jurisdiction	Top provincial or state rate	Approx. combined top marginal rate
Quebec	25.75%	~53.31%
Ontario	~20.53%	~53.5%
British Columbia	~20.5%	~53.5%
Alberta	15%	~48%
Florida	0%	federal only

Do I file with Revenu Québec as well as the CRA?

Yes, and this is the piece every other provincial corridor skips. Every other province has its tax calculated on the T1 itself, administered entirely by the CRA. Quebec is the exception: it issues its own slips (Relevé instead of T4 and T5), assesses separately, and requires its own final TP-1 reporting worldwide income to the departure date. The Quebec abatement, a 16.5% reduction to federal tax that exists because Quebec collects its own tax, gets prorated in the departure year.

• The federal side of the mechanics, including the T1161 and T1243 forms that carry the deemed disposition, is covered in the departure tax forms guide; the full sequencing sits in the leaving-Canada checklist.

• Three things trip up almost every Quebec file at this stage:

• Two notices of assessment, not one. Revenu Québec assesses the TP-1 independently of the CRA’s assessment of the T1, on its own timeline, so a clean federal assessment does not mean the provincial side is closed.

• Relevé slips, not T4 and T5. Quebec employers and payers issue Relevé 1 for employment income and Relevé 3 for investment income, and you need both the federal slip and the Relevé version to complete the two returns correctly.

• The abatement is prorated, not dropped. The Quebec abatement reduces federal tax to offset Quebec collecting its own; in a departure year it applies only to the part of the year you were still a Quebec resident.

Does QST stop the day I leave?

Quebec Sales Tax, 9.975%, stacks with the 5% GST to a combined rate near 15%, close to what an HST province charges. That consumption tax applies to what you buy while you’re a Quebec resident, and it stops mattering to your own filings the moment Quebec residency ends, though any business registered for QST needs its own deregistration steps separate from your personal departure. It is not part of the departure tax calculation and it does not follow you to Florida, where the state runs on sales and use tax instead, charged at a lower rate and with no provincial-style QST layered on top of it.

• A departing business still owes Revenu Québec a formal QST deregistration, separate from the personal filings above.

Is my snowbird pattern already a residency trip wire?

For a lot of Quebec families this is not a fresh move, it is a wintering pattern that has quietly become permanent. Fort Lauderdale, Hollywood, and Hallandale Beach have carried francophone Quebec communities for decades, and Naples and Sarasota draw a steady stream of Quebec retirees further up the Gulf Coast. Years of long winters in Florida push right up against the substantial presence test, and the day count is unforgiving: the formula and how the days are counted and how many days a Canadian snowbird can actually spend in the US both matter well before anyone files a formal departure.

• Filing Form 8840 every year is how a snowbird who is still a Canadian resident stays that way on paper.

What happens to RRQ and OAS once I’m in Florida?

The Régime de rentes du Québec, Quebec’s version of CPP, keeps paying regardless of where you live once you qualify, the same as CPP does for the rest of Canada. OAS and RRQ payments to a US resident are taxed under the treaty rather than under Quebec or federal Canadian rules, and the mechanics work the same way they do for CPP: how CPP and OAS are taxed once you live in the US applies to RRQ recipients without modification.

Can I still get the Florida homestead exemption?

Yes, on the same terms as any other Canadian buyer: you need to own the home and have made it your permanent residence by January 1, and the application (Form DR-501) is due to the county property appraiser by March 1 or the exemption is waived for that year. Nothing about the exemption changes because the seller came from Quebec rather than Ontario or Alberta; the full mechanics, including the assessment cap and what it does and does not do in year one, are worked through in the Ontario-to-Florida corridor guide.

• The one thing Quebec buyers ask about that Ontario buyers usually don’t is Save Our Homes portability, and the answer is the same either way: a prior Quebec home was never a Florida homestead, so there is nothing to port over.

Does RAMQ coverage end the moment I leave?

Not always immediately. The Régie de l’assurance maladie du Québec has reciprocal coverage provisions that can carry a departing resident for a tail of roughly three months after residency ends, but that tail runs out, and it is not a substitute for US health coverage starting on arrival. Provincial health insurance rules on leaving Canada covers how the wind-down works and what to line up before the RAMQ window closes.

• South Florida’s Quebec community makes the healthcare handoff easier than it looks on paper. French-speaking physicians and clinics are established across Broward and Miami-Dade, which is one reason the Fort Lauderdale, Hollywood, and Hallandale Beach corridor has held onto Quebec retirees for decades rather than just wintering them.

What should I do before I file?

Start with the departure date, since the TP-1, the T1, and the deemed disposition all key off it, and work outward from there. Confirm which slips you’re waiting on from Quebec employers or payers (Relevé, not T4), line up your first US return under the new-immigrant filing guide, check what the US-Canada treaty does for income taxed on both sides, and decide what happens to RRSP and TFSA balances before the move using the TN and moving-to-the-US guide.

• Once you’re a US person, FBAR reporting on Canadian accounts starts, covered in who needs to file an FBAR, and a Florida home eventually needs an eye on US estate tax exposure for Canadians.

• The two-authority piece is what makes this corridor different from the other nine provincial versions of the same move, and it is the part most worth planning around before either return gets filed.
