Overview for Markham Retailers

Retail sales in Markham are subject to federal GST/HST rules: Ontario uses the Harmonized Sales Tax (HST). Municipal bylaws do not create separate sales taxes, but local business licensing, permit and inspection rules can affect retail operations and recordkeeping.

Key federal points include the Ontario HST rate and the small-supplier registration threshold; municipal obligations include business licences and compliance with bylaw requirements enforced by By-law Enforcement.

For federal registration and HST details see the CRA guidance. CRA GST/HST for businesses[1]

Charge HST at the point of sale when you are registered and the supply is taxable.

What Retailers Must Do

  • Obtain any required City of Markham business licences for your retail activity.
  • Keep commercial records and receipts that show HST charged and remitted.
  • Contact CRA for tax registration and Markham By-law Enforcement for municipal compliance issues.

HST specifics and registration

Ontario applies HST; the current provincial HST rate information is published by the Canada Revenue Agency. CRA HST rates[2] The CRA also sets the small-supplier threshold that determines mandatory registration.
