Comparing income tax in Alberta vs. Quebec, Alberta wins at every income level, and by a wide margin. Alberta’s provincial rates run from 8% to 15% across six brackets; Quebec’s run from 14% to 25.75% across four. For someone earning $100,000 in 2026, the provincial tax bill alone is roughly $7,500 higher in Quebec, and only part of that is clawed back by the federal-side Quebec Abatement.
Alberta’s 2026 Brackets
Alberta restructured its personal income tax in 2025, adding a new 8% bottom bracket that cut taxes for every resident. For 2026 the province has six brackets:1Government of Alberta. Personal Income Tax
- 8% on the first $61,200
- 10% on $61,200.01 to $154,259
- 12% on $154,259.01 to $185,111
- 13% on $185,111.01 to $246,813
- 14% on $246,813.01 to $370,220
- 15% on everything above $370,220
That 8% starting rate is the lowest provincial rate in Canada, and the 15% top rate doesn’t kick in until income clears $370,220.
Quebec’s 2026 Brackets
Quebec uses four brackets, with the highest provincial rates in the country:2Revenu Québec. Income Tax Rates
- 14% on the first $54,345
- 19% on $54,345.01 to $108,680
- 24% on $108,680.01 to $132,245
- 25.75% on everything above $132,245
Quebec’s lowest rate is nearly double Alberta’s starting rate, and its top rate hits at $132,245. Someone earning $130,000 pays a provincial rate almost 10 percentage points higher in Quebec than in Alberta on their top dollars.
The Federal Side and the Quebec Abatement
Both provinces share the same federal brackets. For 2026 the federal government dropped the lowest rate from 15% to 14%, with rates climbing to 33% on income above $258,482:3Canada Revenue Agency. Income Tax Rates and Income Thresholds
- 14% on the first $58,523
- 20.5% on $58,523.01 to $117,045

- 29% on $181,440.01 to $258,482
- 33% on everything above $258,482
Quebec residents get a partial break through the Quebec Abatement, a 16.5 percentage point reduction on basic federal tax.4Government of Canada. Quebec Abatement The abatement exists because Quebec opted out of certain federal programs and runs them itself. It narrows the gap but doesn’t close it. On $100,000 of income, the abatement saves a Quebec resident roughly $2,750 in federal tax, while the provincial tax premium over Alberta on the same income runs closer to $7,500.
Basic Personal Amount
The Basic Personal Amount is the income you can earn before provincial tax applies. Alberta’s is among the most generous in Canada, historically exceeding $21,000. Quebec’s was $18,571 for 2025, indexed annually.5Revenu Québec. Line 350 – Basic Personal Amount Albertans start owing provincial tax at a higher income level, and the credit itself shelters more of what they earn. On the federal side, the 2026 Basic Personal Amount ranges from $14,829 to $16,452 depending on income, and applies equally in both provinces.6Canada Revenue Agency.

What $100,000 of Income Actually Costs
Simplified, before credits and deductions:
Alberta provincial tax on $100,000 comes to roughly $8,776. That’s 8% on the first $61,200 ($4,896) plus 10% on the remaining $38,800 ($3,880).
Quebec provincial tax on the same income runs about $16,283. That’s 14% on the first $54,345 ($7,608) plus 19% on the next $45,655 ($8,674).
The provincial gap is roughly $7,500. The abatement pulls back about $2,750 through the federal return, so the net income tax difference is around $4,750 in Alberta’s favour. That’s before payroll deductions and sales tax, both of which push the total further apart.
Payroll Deductions Beyond Income Tax
Alberta workers contribute to the Canada Pension Plan at 5.95% of pensionable earnings, matched by their employer.7Canada Revenue Agency. CPP Contribution Rates, Maximums and Exemptions Quebec workers contribute to the Quebec Pension Plan at 6.30% for 2026.8Revenu Québec. Maximum Pensionable Earnings and Quebec Pension Plan Contribution Rate On earnings near the $74,600 pensionable maximum, that 0.35 percentage point spread adds about $260 a year in extra deductions in Quebec.
Quebec workers also pay two things Alberta workers don’t. The Quebec Parental Insurance Plan takes 0.430% of insurable earnings up to $103,000 for 2026, roughly $443 a year at the maximum.9Revenu Québec. Maximum Insurable Earnings and the Quebec Parental Insurance Plan Premium Rate And Quebec is the only province that requires residents to carry prescription drug coverage. If you’re on the public plan run by RAMQ rather than a private employer plan, you pay a premium of up to $766 per person annually through your tax return, scaled to income.10Régie de l’assurance maladie du Québec. Annual Premium Alberta has no equivalent premium.
Sales Tax
Sales tax is where the difference shows up every week. Alberta charges no provincial sales tax, so purchases carry only the 5% federal GST. Quebec adds a 9.975% provincial sales tax to the GST, for a combined 14.975%.11Revenu Québec. Tables of GST and QST Rates On a $50,000 vehicle, that’s roughly $7,488 in sales tax in Quebec against $2,500 in Alberta. Groceries and certain essentials are exempt, but any significant purchase carries the gap.
Filing Is Different in Quebec
In every other province, the Canada Revenue Agency collects both federal and provincial income tax through a single return. Quebec is the exception. Residents file a federal T1 with the CRA and a separate provincial TP-1 with Revenu Québec.12Canada Revenue Agency. Quebec – 2025 Income Tax Package Two sets of rules, two deadlines, two potential refunds or balances owing. People moving from another province often assume the federal return covers everything the first year, and it doesn’t. Budget extra time or a higher preparation fee.
What Quebec’s Higher Taxes Fund
The gap isn’t cost without return. Quebec’s higher taxes fund universal subsidized childcare, more generous parental leave, lower university tuition, and prescription drug coverage. A dual-income family with young children can recover a meaningful share of the tax premium through programs that would cost thousands out of pocket in Alberta. A single high earner with no dependents comes out well ahead in Alberta.
Which Province Taxes You If You Move
Your province of residence on December 31 determines which province taxes your full year of income.13Canada Revenue Agency. Your Province or Territory of Residence Move from Montreal to Calgary in July and Alberta rates apply to your full-year income, including what you earned in Quebec. Move the other direction before year-end and Quebec taxes everything, including Alberta earnings from earlier in the year. If a move is on the table, the timing carries real dollars.
