2018 Corporate Income Tax Rates

The following table shows the general and small business corporate income tax rates federally and for each province and territory for 2018.  The small business rates are the applicable rates after deducting the small business deduction (SBD), which is available to Canadian-controlled private corporations (CCPCs).  The small business rate is available on active business income up to the amount of the Business Limit.  The federal business limit of $500,000 begins to be reduced when a CCPC's taxable capital reaches $10 million, and is eliminated when taxable capital reaches $15 million.  This phase-out of the small business deduction is also in effect in some provinces.

The federal general rate is net of the 10% federal tax abatement and 13% (2012 and later years) general rate reduction.  The general rate reduction is disallowed for a personal services business (PSB), for taxation years beginning after October 31, 2011, resulting in a federal corporate tax rate of 28% for PSBs, until the end of 2015.  The Federal 2016 Budget increased the corporate tax rate for PSBs from 28% to 33% effective January 1, 2016.
