🧾 What Is GST (Goods and Services Tax)?

GST (Goods and Services Tax) is a value-added tax applied on most goods and services sold for domestic consumption. It is paid by consumers but remitted to the government by businesses selling the goods and services.

  • In Canada, GST is a federal tax, and many provinces also apply PST (Provincial Sales Tax) or HST (Harmonized Sales Tax).
  • In India, GST is split into:
    • CGST (Central GST)
    • SGST (State GST)
    • IGST (Integrated GST for inter-state or international transactions)
