Rates of income tax. Corporations are taxed by the federal government
and by one or more provinces or territories. The basic
rate of federal corporate tax for 2015 is 38%, but it is reduced to
15% by an abatement of 10 percentage points on a corporation’s
taxable income earned in a province or territory and a general rate
reduction of 13 percentage points on a corporation’s full-rate taxable
income. Provincial and territorial tax rates are added to the
federal tax and generally vary between 10% and 16% of taxable
income.
The federal government and the provincial and territorial governments
may apply lower rates of tax to active small business earnings
and earnings derived from manufacturing and processing.
Nonresident corporations carrying on business in Canada through
a branch are taxable at the full corporate tax rate on their net business
income earned in Canada, and they must pay an additional
tax (branch tax) of 25% on after-tax income, subject to an allowance
for invest ment in Canadian property. This branch tax may be
reduced by treaty.
