Moving from Montreal to Portland: Taxes, Gaming, and the Departure Tax

Montreal to Portland is a smaller corridor than Montreal’s pull toward Seattle or the Bay Area, but it has a real identity: Ubisoft Montreal alumni and the city’s broader game-studio cluster feed into Portland’s small but growing gaming and creative-tech scene, while Nike in Beaverton and Adidas North America pull in product and digital talent drawn as much by the outdoor lifestyle as the paycheck. The Canada-to-Oregon guide covers the general mechanics; this one runs the Quebec-specific numbers.

How does Quebec’s tax bill compare to Portland’s?

Line the two systems up and the income tax gap nearly disappears. Quebec’s graduated system, with its own provincial bracket topping out at 25.75% on income over roughly $126,000, reaches that ~53.31% combined figure. Portland’s top earners pay Oregon’s 9.9%, plus Multnomah County’s and Metro’s local add-ons, for a combined state-and-local ceiling around 13.9%, landing the all-in federal-plus-state figure close to 50.9%. The real difference sits on the sales tax line.

Tax	Montreal / Quebec	Portland / Oregon
Personal income tax	Combined federal + Quebec top rate ~53.31%	Federal + Oregon 9.9% + local, ~50.9% combined
Sales tax	QST 9.975% + GST 5%, ~14.975% combined	0%, no state or local sales tax
Local income surtax	None separate, built into the Quebec bracket	Multnomah PFA (1.5-3%) + Metro SHS (1%)
Property tax	Varies by borough, generally under 1%	Roughly 1.0% to 1.3% in Multnomah County
Estate tax	None (deemed disposition at death instead)	$1 million threshold, one of the lowest in the US
Separate tax authority	Yes, Revenu Québec	No, one state Department of Revenue

What happens to my Quebec taxes when I leave?

Leaving Quebec triggers the standard departure tax: a deemed disposition of your worldwide property at fair market value on your departure date, reported on your final TP-1. Unvested equity and a non-registered brokerage account with real gains both get caught here. Quebec’s provincial bracket tops out at 25.75% on income over roughly $126,000, stacked on federal brackets to reach that ~53.31% combined figure, so a large departure-year gain can push a meaningful slice of it into that top bracket.

Which three tax authorities apply in the move year?

The CRA, Revenu Québec, and the IRS, and that’s before Oregon even enters the picture. The final TP-1 goes to Revenu Québec, covering worldwide income to the departure date. The final T1 goes to the CRA, covering the same period federally. The IRS then gets a US return, dual-status or full-year under the first-year election, and Oregon layers a part-year state return on top of that.

What replaces my T4 and T5 on the way out?

Relevé slips. Quebec issues its own alongside the federal ones, the Relevé 1 for employment income next to the T4, and the Relevé 3 for investment income next to the T5. A partial-year Montreal employer, common for anyone leaving mid-project, often issues the Relevé 1 weeks after the T4 lands. The Quebec abatement, a 16.5% reduction of basic federal tax, has to be prorated to the actual months of Quebec residency in a departure year, not claimed in full.

Does RAMQ coverage end the day I leave?

No. RAMQ coverage runs for the balance of the month you leave plus roughly three more months, a tail most departing Quebecers don’t budget for. After that window closes, you need Oregon-side coverage, and Nike, Adidas, and the larger Portland-area employers all offer plans from day one, but a gap can still open if the move date and the plan start date don’t line up.

What are the Multnomah County and Metro taxes?

Living in Portland proper means two local taxes stack on top of the state rate, the piece of this corridor that has no real Quebec equivalent, since Quebec runs through one provincial authority. Metro’s Supportive Housing Services tax adds 1% above $125,000 single or $200,000 joint. Multnomah County’s Preschool for All tax adds 1.5% above the same thresholds, rising to 3% above $250,000 single or $400,000 joint.

• A household earning $300,000 joint inside Portland proper pays roughly 1% (Metro SHS) plus 3% (Multnomah PFA at the top bracket) on top of the 9.9% state rate, a combined marginal bite near 13.9%.
• Move to Washington County, home to Intel’s Hillsboro campus and much of the Nike and Adidas corridor, and neither local tax applies at all.

Is this actually a tax-savings move?

No, and that’s worth saying plainly. Quebec’s ~53.31% top rate and Portland’s ~50.9% all-in figure sit close enough that income tax isn’t the reason to make this move. What changes is which tax collects the money: Quebec pairs high income tax with a combined QST-and-GST rate near 14.975% on nearly everything you buy, while Oregon collects almost all of it through income tax and charges zero sales tax. For a high earner with moderate spending, that swap can still net out ahead.

What about Oregon’s estate tax?

Quebec has no estate tax, relying on the deemed-disposition rule at death instead. Oregon applies its own estate tax above a $1 million exemption, one of the lowest thresholds in the country, so a Portland-area home plus retirement accounts and any equity position can cross that line faster than people expect. It’s a real planning item for anyone settling permanently rather than treating the move as temporary.

Where do Montreal transplants actually land?

The Pearl District and Northwest Portland draw the younger crowd wanting walkability and proximity to the small gaming and creative-tech studios downtown. Beaverton and Hillsboro form the real Nike, Adidas, and Intel corridor, and both sit in Washington County, entirely outside Multnomah’s local taxes. Alberta Arts and Mississippi offer a walkable, creative feel closer to what a Mile End or Plateau transplant might expect, and Lake Oswego pulls a higher-income crowd wanting more space, also outside Multnomah County.

What should I do before the move?

Close the Quebec side first: confirm the departure date, gather both the T4/T1 and Relevé/TP-1 slip sets, deregister for QST if applicable, and prorate the Quebec abatement to the actual months of residency. Confirm whether your new address sits inside Multnomah County or Washington County before you sign a lease, since that decides whether either local tax applies at all. Line up Oregon-side health coverage before the RAMQ tail runs out at three months.
