Formula for Quebec Sales Tax

GST = Price_{before\_tax} \times 5\%

Price_{with\_GST} = Price_{before\_tax} + GST

QST = Price_{with\_GST} \times 9.975\%

Total\_Tax = GST + QST

Total\_Price = Price_{before\_tax} + Total\_Tax

Understanding Quebec Sales Tax (QST)

In Quebec, consumers pay two types of sales tax: the federal Goods and Services Tax (GST) and the provincial Quebec Sales Tax (QST). Unlike other provinces where PST is calculated on the price before GST, QST is calculated on the price that already includes the GST. This 'tax on tax' approach is unique to Quebec.

  • GST: A federal tax applied across Canada.
  • QST: A provincial tax specific to Quebec, administered by Revenu Québec.

How GST (Federal Tax) is Calculated

The Goods and Services Tax (GST) is a 5% federal tax applied to most goods and services sold in Canada. It's a uniform rate across all provinces and territories. Businesses that are registered for GST/HST collect this tax on behalf of the Canada Revenue Agency (CRA).

For example, if an item costs $100 before tax, the GST portion would be $5.

How QST (Provincial Tax) is Calculated

The Quebec Sales Tax (QST) is currently set at 9.975%. What makes QST distinct is that it is applied to the price of the good or service after the 5% GST has been added. This means you are essentially paying provincial tax on the federal tax portion as well.

Consider an item priced at $100:

  • Original Price: $100.00
  • GST (5%): $5.00
  • Subtotal (Price + GST): $105.00
  • QST (9.975% of $105.00): $10.47
  • Total Tax: $5.00 + $10.47 = $15.47
  • Final Price: $100.00 + $15.47 = $115.47

Important Considerations and Exemptions

While most goods and services are subject to GST and QST in Quebec, there are certain exceptions and considerations:

  • Exempt Supplies: Some basic groceries, certain health care and dental services, and residential rents are generally exempt from GST and QST.
  • Zero-Rated Supplies: Exported goods and certain medical devices are 'zero-rated', meaning GST and QST are technically applied at a 0% rate, allowing businesses to claim input tax credits.
  • Digital Services: Foreign digital service providers selling to Quebec consumers must also register for and collect QST.
  • Always verify current rates and exemptions with official government sources for the most accurate information.
