The Canada Revenue Agency (CRA) administers Ontario's corporate income tax, capital tax, corporate minimum tax, and the special additional tax on life insurers.

Capital Tax is a tax charged on a corporation's taxable capital. Taxable capital is the amount determined under Part 1.3 of the Income Tax Act (Canada) plus accumulated other comprehensive income.

Effective July 1, 2010 capital tax was eliminated. It was eliminated effective January 1, 2007 for Ontario corporations primarily engaged in manufacturing or resource activities.
