When should I collect sales tax in Ontario?

When starting a company or personal business you may begin to question how you should charge sales tax to adhere to federal and provincial laws in accordance with sales. Taxable items can extend from physical items to properties and even digitalized goods.

When evaluating if you need to be applying HST to the goods you are selling it is important to recognize that taxable goods and services should exceed $30,000 in revenue in a single calendar year before qualifying for HST. This applies to service providers and property providers regardless of taxable service.

The total taxable revenue should exceed CAD 30,000 in a single calendar quarter or four separate consecutive calendar quarters. If you are selling wholesale to another business this does not make you tax exempt, but instead, it is the responsibility of the business you are selling, to claim the tax credit on their purchases from your wholesale company.

How are sales taxes calculated in Ontario?

In Ontario, Canada the province charges a Harmonized Sales Tax (HST) of 13%. This accounts for the federal government collection of GST, at the rate of 5%, and the provincial departments’ charge of 8% on taxable supplies. These together generate the HST of 13% for the entire province of Ontario for taxable goods and services.

Some provinces follow the same method as Ontario while other provinces keep their taxes separated into GST and PST. All provinces are required to apply the 5% federal tax on taxable services, but the provincial tax rate may vary. For example, Saskatchewan utilizes the application of GST (5%) and PST (6%). The Maritimes have the highest HST with all maritime provinces reaching an HST of 15% in comparison to Ontario’s 13%.

The HST is applied to taxable items for example when purchasing a taxable item, it may be listed as $20.99 plus tax. So, upon purchasing this item the HST would take federal tax of 5% plus the provincial tax of 8% from the $20.99 listed item, this would accumulate to $2.73 in taxes owed and would result in the items total price being $23.72.
