Harmonized Sales Tax

A Harmonized Sales Tax (HST) of 13% came into effect in the Province of Ontario on July 1, 2010.  The HST is a combination of the Goods and Services Tax (GST) of 5% and the provincial component of 8%.

The Goods and Services Tax (GST) is a tax that applies to the supply of most property and services in Canada. The province of Ontario has elected to harmonize the provincial and Goods and Services taxes. Generally, HST applies to the same base of property and services as the GST.

Financial Services posts all taxable expenses to the appropriate account net of tax rebates; for this reason, the total amount invoiced will not necessarily match the amount in your account.

When Selling to External Parties

HST on the Sale of Goods and Services

HST of 13% is charged on Goods and Services to External parties. Commercial Operations are required to charge and collect tax from their customers.

Other Units when selling goods and services may be required to charge and collect tax from their customers. Since we are a University most of our services are exempt from HST.  See the HST Tax Table for Sales to External Parties it includes a listing of specific goods and services, the tax applicability along with the tax rate to charge.

If you are invoicing other provinces for goods and services you may need to charge HST or GST applicable to that province. See the Tax Rates by Province for Sales to External Parties for the HST or GST rate to charge.  The harmonized Provinces are charged their applicable HST rate and all other provinces/territories should be charged GST (5%) only.

Tax collected is credited to the corporate account UW82 105400. Instructions for charging HST through Western Financials Billing are included in the Billing Training documentation.
