This article presents a broad overview of the corporate income tax (CIT) in Canada. Historical data are presented relating to statutory tax rates, revenue shares, tax to gross domestic product ratios, and various effective tax rate measures. A notable feature of the data is the substantial reduction in statutory and effective tax rates over the last several decades, without a marked reduction in revenue, measured in several ways. The article concludes with a brief discussion of the future role of the CIT in Canada.
