Notes

(1) The small business income thresholds shown in the table apply to active business income 

earned by a Canadian-controlled private corporation (CCPC) that is eligible for the small 

business rate of tax (see the tables “Federal and Provincial /Territorial Tax Rates for Income 

Earned by a CCPC Effective January 1, 2013 and 2014” and “Combined Federal and 

Provincial/Territorial Tax Rates for Income Earned by a CCPC Effective January 1, 2013 and 

2014”). All thresholds must be shared by associated corporations.

(2) The federal small business threshold is reduced on a straight-line basis when the 

associated group’s taxable capital (as computed by what was previously referred to as 

Large Corporations Tax) employed in Canada in the preceding year is between $10 million 

and $15 million. This clawback applies to all provinces, with the exception of Ontario (see 

note (4) below).

(3) Manitoba’s small business income threshold will increase to $425,000 (from $400,000) on 

January 1, 2014.

(4) Previously, Ontario levied a surtax at a rate of 4.25% on CCPCs claiming the Ontario small 

business deduction in order to gradually reduce the benefit of the deduction where taxable 

income exceeded the small business income threshold. Based on the small business limit 

of $500,000, the phase-out range for the application of the surtax was between $500,000 

and $1.5 million. The province eliminated this small business deduction surtax effective 

July 1, 2010 and, as a result, all CCPCs will benefit from the small business deduction on 

the first $500,000 of active business income (shared between associated corporations) 

irrespective of the corporation’s taxable income.

(5) Québec’s small business deduction is available to CCPCs with paid-up capital (on an 

associated basis) of less than $10 million, and is phased out for CCPCs with paid-up capital 

between $10 and $15 million.

(6) Nova Scotia’s small business income threshold will decrease to $350,000 (from $400,000) 

effective January 1, 2014.
