Ontario Tax Brackets 2026

Every Ontario bracket, marginal rate, effective rate, and surtax threshold in one place

Ontario uses a five-bracket progressive income tax system for 2026. Each bracket only applies to income within that range — earning more never means paying more tax on income you already earned at a lower rate. This guide provides the complete Ontario tax bracket table with marginal rates, effective rates at key income levels, and the surtax thresholds that catch many high earners off guard.

How Ontario Brackets Changed from 2025 to 2026

Ontario tax brackets are indexed annually to inflation using the Ontario CPI. In 2026, all five bracket thresholds increased by approximately 2.7% compared to 2025 levels. The surtax thresholds of $5,554 and $7,108 also adjusted slightly upward. This indexation prevents "bracket creep" — the phenomenon where inflation pushes taxpayers into higher brackets without real income growth.

What Income Triggers Each Ontario Bracket?

The second Ontario bracket (9.15%) begins at $51,446 of taxable income — after subtracting the basic personal amount of $11,865, this corresponds to gross employment income of about $63,311. The top bracket at 13.16% begins at $220,000 of taxable income, or roughly $231,865 in gross employment income for most employees.
