Many of the services and benefits Ontarians enjoy are made possible through taxes. Ontario's tax system funds integral services such as roads and highways, health care, hospitals, education, social services, provincial parks and the environment.
Interest is charged to your account if payment is not received by the due date. Remember: if the due date falls on a weekend or holiday, your payment is due the next working day.
The Ministry of Revenue also applies interest to amounts the ministry owes to individuals and corporations.
Interest is compounded daily and the interest rates are reset every three months.
Provincial Sales Tax (PST), also known as Retail Sales Tax, is a tax that is collected by the Ontario government when taxable goods (e.g. a CD) or taxable services are sold. The general tax rate of 8% is charged on the selling price of the good or service. For example, if a CD is sold for $10, the PST would be 80 cents.
Other PST rates apply to certain accommodations, admissions, and alcoholic beverages.
