Ontario Corporate Tax Rates 2026

Ontario has some of the most favourable small business corporate tax rates in Canada. Here are the combined federal + Ontario rates:

Income Type Federal Rate Ontario Rate Combined Rate
Active business income (CCPC, first $500K) 9.0% 3.2% 12.2%
Active business income (above $500K) 15.0% 11.5% 26.5%
Investment/passive income 38.67% 11.5% 50.17%

Ontario's 12.2% small business rate is one of the lowest in Canada. An Ontario CCPC earning $500,000 in active business income pays just $61,000 in corporate tax โ€” leaving $439,000 to reinvest or transfer to a holding company.


Ontario-Specific Tax Considerations

Ontario HST โ€” 13%

Ontario uses a Harmonized Sales Tax (HST) of 13% โ€” administered federally by CRA. Once your business revenue exceeds $30,000, you must register and collect HST. Ontario businesses selling to customers in other provinces charge the rate applicable to the customer's province.

Ontario Small Business Deduction (SBD)

Ontario provides its own provincial small business deduction of 3.2% (2026) on the first $500,000 of active business income for CCPCs โ€” on top of the federal 9% SBD. This gives Ontario CCPCs a combined 12.2% rate on qualifying income.

Ontario Trillium Benefit

For business owner-managers who also have lower personal income in some years, the Ontario Trillium Benefit provides up to $1,600+/year in combined energy, property tax, and sales tax credits โ€” claimed on your Ontario T1 return.

Ontario Corporate Minimum Tax (CMT)

Larger Ontario corporations with total assets above $50 million or revenues above $100 million are subject to Ontario's Corporate Minimum Tax. Most small businesses are not affected, but it applies if you are scaling toward these thresholds.

Employer Health Tax (EHT)

Ontario employers with payroll above $1,000,000 pay the Employer Health Tax (EHT) โ€” 1.95% on payroll above the exemption amount. For growing Ontario businesses, EHT planning is an important part of payroll strategy.
