Canadian Sales Tax (GST, HST & PST)

Canada charges sales tax on goods and services sold. Depending on the province, you will pay either the federal Goods and Services Tax (GST), Provincial Sales Tax (PST), or a combined Harmonized Sales Tax (HST).

How to Add or Remove Canadian Sales Tax

Calculation depends on provincial sales tax structures:

  1. Identify Local Tax Structure: Determine whether your province uses GST (5%), GST+PST (e.g. 5% + 7% in BC), or HST (e.g. 13% in Ontario, 15% in Atlantic provinces).
  2. Add Sales Tax: Price with Tax = Pre-Tax Price * (1 + Tax Rate).
  3. Remove Sales Tax: Pre-Tax Price = Price with Tax / (1 + Tax Rate).
