Moving from Montreal to Salt Lake City: Taxes, Three Authorities, and Silicon Slopes

Montreal’s AI and gaming talent has a natural landing spot in Silicon Slopes, the tech corridor running from Salt Lake City south through Draper, Lehi, and Provo. Adobe’s Lehi campus draws on the same creative-tech skill set that built Montreal’s game studios, Qualtrics and SAP pull from the analytics and data side, and Pluralsight recruits edtech and learning talent out of the same pool. The lifestyle pitch adds to it: real mountains, real skiing, none of Montreal’s winter without the payoff. The tax math is just as dramatic, but Quebec closes its file through two of its own authorities, on top of the IRS, before any of that Utah simplicity kicks in.

Why is the rate drop so steep from Quebec?

Quebec stacks a five-bracket provincial system, topping out at 25.75%, on top of federal tax, and no other province runs a top bracket that high. Utah replaces all of that with a single flat 4.65% rate applied to federal taxable income, no brackets to climb and no separate provincial-style schedule for investment income. The combined difference, roughly 53.31% at the top in Quebec versus a combined rate in the low 40s in Utah, is one of the largest rate drops in this corridor series.

Tax	Montreal / Quebec	Salt Lake City / Utah
Provincial / state income tax	Up to 25.75%	Flat 4.65%
City income tax	None	None
Combined top marginal rate	About 53.31%	Roughly low 40s
Sales tax	QST 9.975% + GST 5%, about 14.975%	About 7.75% combined in SLC
Property tax (effective rate)	Roughly 0.8% to 1.2%	Roughly 0.5% to 0.7%
Health insurance	RAMQ, provincial, notice-based wind-down	No state program; employer plan or ACA marketplace
Estate tax	Quebec has none; watch US estate exposure	Utah has no state estate or inheritance tax

Which three authorities does the departure run through?

Quebec is the only province that collects its own income tax directly instead of letting the CRA administer a combined federal-and-provincial return, and that structure shows up in full the year you leave. The CRA takes the final T1, covering worldwide income to the departure date. Revenu Quebec takes a separate final TP-1 on the same income, and issues its own slips, Releve 1 for employment income and Releve 3 for investment income, in place of the T4 and T5 every other province uses.

• Only once both provincial and federal Canadian filings are done does the IRS become the third authority on the file, since Utah’s state return simply rides on the federal number rather than adding a fourth layer.
• Anyone billing consulting income through a Quebec-incorporated company also carries a Health Services Fund account, which needs its own wind-down separate from the personal TP-1.
• The federal departure mechanics, Form T1161 and T1243, apply the same way regardless of destination; the full sequence sits in the leaving-Canada checklist.

What are Releve slips and why do they matter here?

They’re Quebec’s own version of the T4 and T5, and Utah’s tax preparer or software has no template for them. A Montreal employer issues a Releve 1 alongside (not instead of) the T4 for the departure-year period, and any Quebec-source investment income shows up on a Releve 3 alongside the T5. Both get used to build the final TP-1, and both need to survive the paper trail into the eventual US return, since the same income has to reconcile against whatever the IRS sees on the arrival-year federal return.

How does Utah’s flat tax actually work?

There’s no bracket to track and no threshold to cross, which is a real simplification after a system layering federal brackets, a provincial schedule, and an abatement calculation on top of each other. Utah starts from federal taxable income and applies 4.65% straight through, on wages, on bonuses, and on capital gains alike, with no separate state schedule for investment income.

• Salt Lake City and every Utah city add no local income tax on top, unlike some US metros where a city-level tax stacks on the state rate regardless of the state’s headline number.
• A nonrefundable taxpayer tax credit tied to the federal standard or itemized deduction trims the effective rate further for low and middle incomes, and a retirement income credit worth up to $450 per person applies at 65 and older.

What happens to the RRSP and TFSA in Utah?

The RRSP keeps its treaty deferral without friction. Because Utah computes tax starting from federal taxable income, and treaty deferral under Article XVIII keeps RRSP growth out of that federal number, Utah never sees the income and never taxes it, no separate addback the way California runs. Withdrawals flow through federal taxable income first and hit Utah’s flat 4.65% along with everything else, with Canadian withholding generally absorbed by the foreign tax credit.

• The TFSA gets no equivalent break. It’s a foreign trust for US purposes regardless of which state you land in, meaning ongoing Form 3520/3520-A exposure and PFIC analysis on anything held inside it. The standard move is collapsing it before departure, covered in the RRSP and TFSA guide.

Does sales tax and property tax go up or down?

Both move in the buyer’s favor, sales tax dramatically and property tax more modestly. QST at 9.975% stacked with 5% GST runs to about 14.975% combined, among the higher consumption tax burdens in North America. Salt Lake City’s combined state and local sales tax runs around 7.75%, roughly half the Quebec rate on every purchase. Property tax moves the same direction on a smaller scale: Montreal’s effective rate typically runs 0.8% to 1.2% of assessed value, while Utah assesses primary residences at only 55% of fair market value, producing an effective rate closer to 0.5% to 0.7%.

What happens to RAMQ once you’re in Salt Lake City?

RAMQ coverage runs a reciprocal tail of roughly three months past the date you notify the board of a permanent departure, and that notice has to be filed directly, it doesn’t trigger on its own. Utah has no state health program to replace it. The move itself is a Special Enrollment Period event on the federal marketplace, giving 60 days from the move date to enroll in an employer plan or healthcare.gov coverage before the RAMQ tail runs out.

Why does Montreal feed Silicon Slopes specifically?

Adobe’s Lehi campus draws directly on Montreal’s creative-tech and gaming talent, the same skill set built by the city’s game studios and reinforced by McGill and UdeM computer science graduates. Qualtrics and SAP in Provo pull from the data and analytics side of that same pool, and Pluralsight in Draper recruits edtech and learning-platform talent with real overlap to Montreal’s ed-tech and gaming crossover roles.

• Lucid Software and Domo add SaaS-specific demand, while Goldman Sachs’ Salt Lake City office pulls a smaller but real slice of Montreal’s finance-adjacent tech talent.
• Droits de mutation, Quebec’s welcome tax on property purchases, is a cost Montreal movers leave behind entirely; Utah has no equivalent transfer tax on the buying side.

What should I do before the move?

Pin the departure date early, since it sets the prorated Quebec abatement, fixes the deemed-disposition rate on the final TP-1, and starts the RAMQ clock. Pull a full year of RRSP and non-registered account statements, and if consulting income runs through a Quebec corporation, get its QST and GST deregistrations ready to file alongside the personal return. Then line up the Utah side: a part-year state return, US health coverage inside the 60-day marketplace window, and confirmation of which employer is handling visa and relocation mechanics.
