What is the Small Business Tax Rate in Canada?

[fa icon="calendar"] Jan 23, 2023 2:10:00 PM / by Koroll & Company

Blog 4In Canada, the general corporate tax rate is 15%, after the federal tax abatement of 10% and the general tax reduction of 13%. However, small businesses have a reduced federal tax rate of 9%. 

Each province and territory also has their own corporate and small business tax rates. In Ontario, the general corporate tax rate is 11.5%. The small business tax rate is 3.2%. This means that the combined federal and provincial taxes paid on active business income is 26.5% for corporations in general, and 12.2% for small businesses. 

This is a substantial tax saving

But what qualifies a business as a small business?

Small businesses are Canadian-controlled private corporations (CCPCs) that qualify for the small business deduction (SBD). 

The small business deduction provides corporations with a reduced tax rate on up to $500,000 of active business income. Federally, this can save businesses up to $30,000 in taxes every year federally. Businesses would also have reduced provincial taxes as well.  

This $500,000 is claimed by a single corporation or a group of CCPC that are associated for income tax purposes. 

There are, however, limitations on who can claim the small business deduction.

Firstly, the SBD will be gradually reduced for a CCPC (or group of CCPCs) when taxable capital exceeds $10 million. Once a CCPC has $15 million in taxable capital, the SBD is eliminated. 

However, the 2022 budget proposed to change the upper limit of the reduction window to $50 million in taxable capital. This would allow more CCPCs to be eligible for the reduced small business tax rate. The proposed change will be available to CCPCs whose tax year starts on or after April 7, 2022. If your business has a calendar year end, the change will be effective in the 2023 tax year. 

Under the current SBD program, the SBD reduces by $100,000 for every $1 million of taxable income, zeroing out at $15 million in taxable capital. Under the proposed changes, the reduction amount would be $12,500 for every $1 million of taxable capital, zeroing out at $50 million. 

In addition to the taxable capital restrictions, there’s an additional restriction to the SBD amount when a CCPC (or group of associated CCPCs) has investment income exceeding $50,000 in a given taxation year. In these situations, the SBD is slowly reduced and is eliminated once investment income exceeds $150,000.
