Ontario's Tax System

Learn about Ontario's major tax statutes, tax credit, incentives and benefit programs.

Ontario's major tax statutes as well as a number of tax credit, incentive and benefit programs form Ontario's tax system. The tax revenues collected support the province's programs and investments in education, health care, transportation infrastructure and skills.

The Ministry of Finance promotes the integrity of the province's self-assessing tax system by encouraging compliance through taxpayer education and customer service, while discouraging non-compliance through enforcement activities.
