Ontario vs BC Tax Calculator 2025

How Ontario and BC Income Tax Compare in 2025

Ontario and British Columbia both use progressive provincial tax systems layered on top of the same federal income tax. The key difference lies in their provincial brackets and rates. Ontario has five provincial brackets topping out at 13.16%, but it also levies a surtax — an extra charge on provincial tax itself — that significantly raises the effective rate for incomes above roughly $80,000. BC uses seven brackets reaching up to 20.5% on income over $240,716, but has no surtax, making it more predictable for high earners. Based on 2025 rates from the Canada Revenue Agency and provincial revenue ministries, this calculator gives you an accurate side-by-side breakdown including federal tax, provincial tax, CPP, EI, total deductions, and net take-home.

Ontario Provincial Tax: Brackets and Surtax Explained

Ontario's provincial income tax starts at 5.05% on income up to $51,446, rising to 9.15% on the next band, then 11.16%, 12.16%, and 13.16% on income over $220,000. After calculating the base provincial tax, Ontario applies a surtax: 20% on any provincial tax above $5,461, plus an additional 36% on provincial tax above $6,943. This surtax is added on top of the regular provincial tax, not on income. The combined effect means an Ontario taxpayer earning $100,000 pays considerably more provincial tax than the headline rate suggests. The Ontario basic personal amount for 2025 is $11,865 (provincial) and $15,705 (federal), meaning the first $11,865 of income is tax-free at the provincial level.

BC Provincial Tax: Seven Brackets, No Surtax

British Columbia's provincial tax is structured around seven brackets for 2025: 5.06% on income up to $45,654, then 7.70%, 10.50%, 12.29%, 14.70%, 16.80%, and 20.50% on income over $240,716. Crucially, BC has no provincial surtax, so the rate you calculate from the brackets is exactly what you pay. BC's basic personal amount is $11,981 — slightly higher than Ontario's. For incomes between $50,000 and $130,000, Ontario and BC are competitive. However, once income climbs above $130,000, Ontario's surtax takes a growing bite, and BC typically becomes the lower-tax province by a measurable margin.

CPP, EI and Federal Tax: What Both Provinces Share

Federal income tax is identical regardless of province: 15% on income up to $57,375, 20.5% on the next band up to $114,750, 26% up to $158,519, 29% up to $220,000, and 33% above that. The federal basic personal amount is $15,705. Canada Pension Plan (CPP) contributions for 2025 are 5.95% on employment income between $3,500 and $68,500, capped at $3,867 per year. Employment Insurance (EI) premiums are 1.66% on insurable earnings up to $63,200, capped at $1,049. These figures are the same for all provinces, so the only variable in this comparison is the provincial component. Both CPP and EI reduce your federal taxable income through non-refundable tax credits at the 15% federal rate.
