Which Canadian Province Has the Highest Taxes? 2025

Updated March 2025 • bremo.io

While most Canadians focus on federal taxes, provincial taxes can swing your total tax bill by $100–$30,000 or more depending on income. The highest-tax provinces are a clear cluster of Atlantic Canada and Quebec, with some nuances depending on income level.

Highest Combined Marginal Rate: Nova Scotia at ~54%

For income above $220,000, Nova Scotia's combined federal and provincial marginal rate reaches approximately 54%. This is the result of a 21% provincial rate on income above $150,000 stacking with the federal 33% rate above $220,000.

Highest Taxes for Middle-Income Earners: Quebec

Quebec's top rate of 25.75% kicks in at just $119,910 — the lowest income threshold for a top provincial rate in Canada. This means someone earning $130,000 in Quebec is already paying 25.75% provincially, while the same earner in Alberta pays just 10%.

For a $120,000 income, Quebec adds approximately $100–$13,000 more in provincial income tax compared to Alberta, even after accounting for the federal Quebec abatement.

Quebec's 15% Sales Tax

Quebec's combined GST + QST reaches approximately 14.975% — essentially the same as the Atlantic HST provinces. Combined with high income taxes, Quebec carries the heaviest overall tax burden for middle-class earners in Canada.

Most Expensive Province Overall: Quebec for Families

Surprisingly, for many families with young children, Quebec is NOT the most expensive on an after-services basis. Quebec's $10.35/day subsidized daycare saves families $15,000–$30,000 per year compared to Ontario or BC. Even with higher income taxes and sales taxes, a Quebec family with two children in daycare may come out significantly ahead of an Ontario or BC equivalent.

The math depends heavily on family structure. Single professionals or couples without children bear Quebec's full tax burden with none of the childcare savings.

Atlantic Provinces: High Sales Tax, Moderate-High Income Tax

All four Atlantic provinces (Nova Scotia, New Brunswick, PEI, Newfoundland) charge 15% HST — the highest sales tax in Canada. They also have higher income tax rates than western Canada. On a $70,000 income, an Atlantic resident pays:

• Approximately $2,000–$4,000 more in income tax than an Albertan
• Approximately $2,500–$3,500 more in sales tax on typical spending
• Total extra tax burden: $4,500–$7,500/year vs Alberta

Why Do High-Tax Provinces Exist?

High-tax provinces generally share characteristics:

• Smaller populations: Fixed government costs spread over fewer taxpayers
• Aging populations: Higher per-capita healthcare and social costs
• Lower economic output per capita: Less corporate and high-income tax revenue available
• Historical infrastructure: Older cities with higher maintenance costs
• Political choices: Decisions to fund more services vs. cut taxes

Is There a "Best" Province for Taxes?

Yes — Alberta, for most income levels. But tax optimization should always be balanced against quality of life, employment opportunities, housing costs, and proximity to family. The "right" province depends on your entire financial picture, not just the marginal rate on your last dollar of income.
