HST stands for Harmonized Sales Tax and is the emerging tax standard for Canadian Provinces. When you select HST as the tax option in your store the cart uses the tax table to lookup the province and get the tax rate. HST is only charged for customers in your home province. This option requires that you add provinces you want to charge tax in to the “Smith_Tax” table. Product prices should be entered exclusive of tax – meaning tax is not included in the product price when entering products in the product setup screen.
