Quebec's tax load tops North America, but refunds soften impact for many

A study by researchers at the Université de Sherbrooke shows Quebec’s total tax collection, measured against GDP, is the highest among Canadian provinces and surpasses all U.S. states and Mexico at 38.6% for 2024. This “overall tax burden” places the province near the OECD average. At the individual level, Quebec’s gross tax load is second only to Nova Scotia, but when refundable credits and family allowances are accounted for, the net burden falls below that of four other provinces.

A single-parent family earning $56,714 receives 12% more in transfers than it pays in taxes, while a high-income single earner faces a net rate near 35%, the nation’s highest. These transfers dramatically lower the Gini coefficient from 0.43 to 0.27, indicating reduced inequality. Researchers cite the system’s role in keeping Quebec’s poverty rate well below Ontario’s. The findings challenge political claims that the province’s tax regime is uniformly burdensome, showing benefits for lower-income residents despite higher rates for corporations and affluent individuals.
