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.
