In Canada, sales taxes are applied in three different ways:

  • The value-added Goods and Services Tax (GST). The federal government applies the GST.
  • The provincial sales tax (PST), is imposed by the provinces. It is also sometimes known as the retail sales tax.
  • The value-added Harmonized Sales Tax (HST), is a single type of tax that is an amalgamation of the GST and PST.
  • Current (2020) GST ratein Canada is 5% and QST rate in Québec is 975%
