Corporation tax rates

Important notice

For tax years that end after 2015, changes have been announced to the small business tax rate. Go to What's new for corporations.

Federal rates

The basic rate of Part I tax is 38% of your taxable income, 28% after federal tax abatement.

After the general tax reduction, the net tax rate is:

  • 15% effective January 1, 2012
  • 16.5% effective January 1, 2011
  • 18% effective January 1, 2010

For Canadian-controlled private corporations claiming the small business deduction, the net tax rate is 11%.

Provincial or territorial rates

Generally, provinces and territories have two rates of income tax – a lower rate and a higher rate.

Lower rate

The lower rate applies to the income eligible for the federal small business deduction. One component of the small business deduction is the business limit. Some provinces or territories choose to use the federal business limit. Others establish their own business limit.

Higher rate

The higher rate applies to all other income.
