Effective Tax Rate
The effective tax rate is your total income tax paid divided by your total gross income, expressed as a percentage. Because Canada uses progressive brackets, your effective rate is always lower than your marginal rate — lower portions of income are taxed at lower rates before higher brackets apply.
For example, a Canadian earning $80,000 in Ontario pays approximately $16,500 in combined federal and provincial tax, giving an effective rate of about 20.6% — well below the combined marginal rate of 31.5%. At $150,000, the effective rate rises to roughly 28%, despite a marginal rate around 33.9%.
The effective rate gives you a more realistic picture of your overall tax burden and is useful for comparing tax loads across provinces or countries. When someone says "I pay 33% tax," they likely mean their marginal rate — their effective rate is considerably lower.
