According to Luc Godbout, professor and research chair in taxation and public finance at the Université de Sherbrooke, Quebec’s overall tax burden—calculated as the sum of federal, provincial and municipal taxes paid by individuals and businesses divided by provincial GDP—stood at 38.6 percent of GDP in 2024, the highest proportion among Canada’s ten provinces and even above the United States and Mexico.

Godbout further notes that Quebec’s gross individual tax burden—encompassing personal income tax, social contributions and consumption taxes—is heavier than that of every other province save Nova Scotia; however, when refundable credits and direct family allowances are deducted to obtain the net tax burden, Quebec falls below Nova Scotia, Prince Edward Island, Newfoundland and Labrador, and New Brunswick.

The study’s household‑level simulations reveal that a single‑parent family earning $56,714—a figure roughly two‑thirds of the provincial average wage—receives 12 percent more in government transfers than it contributes in taxes, representing the lowest net tax burden of any Canadian jurisdiction.

Conversely, a childless individual with an income of $141,362—approximately two‑thirds higher than the average wage—confronts a net tax burden approaching 35 percent, the steepest in the country.

These divergent outcomes illustrate how Quebec’s tax architecture compresses the wealth gap: by converting a high gross levy into a progressive net effect, the system shields vulnerable households while extracting a larger share from affluent earners, a dynamic that underpins both political rhetoric and policy design.

Thus, the label of “most taxed” is technically accurate in aggregate terms, yet it obscures the province’s capacity to redistribute wealth and lighten the fiscal load for those who need it most.
