Step 1 - What is the HST Number


View this quick video to learn more about GST/HST Accounts.


Most persons and organizations engaged in commercial activities in Canada who have worldwide, taxable sales of more than $30,000 over any four or fewer consecutive calendar quarters must apply for, register and collect the Harmonized Sales Tax (HST). All taxi and limousine operators must register for HST, regardless of their revenues.

What is the Federal Business Number (BN)?
The BN is issued by the Canada Revenue Agency (CRA) and is used to unify all accounts a business may have with the federal government. The BN is used to operate corporate income tax, import/export accounts, payroll deductions and GST/HST among others.

When should I apply for the Federal Business Number (BN)?
Registration should take place after the company has been registered. We can assist you with both, the business registration and the HST registration at the same time.

General Information about HST
The HST applies to most transactions from manufacturing to marketing and sales. Businesses and organizations registered for the HST are referred to as registrants. In general, a harmonized sales tax rate of 13% applies to most goods and services. The HST is not charged on the following items:

  • Basic groceries
  • Prescription drugs
  • Some medical devices
  • Municipal public transit
  • Health and education services
  • Legal aid
  • Most financial services
  • Child care
  • Tutoring
  • Music lessons
  • Residential rents

Businesses do not collect the provincial portion (eight per cent) of the HST for:

  • Qualified prepared food and beverages sold for a total of $4 and under
  • Print newspapers
  • Children's clothing and footwear
  • Children's car seats and car booster seats
  • Diapers
  • Feminine hygiene products
  • Books (including audio books)

HST registrants who provide taxable goods or services have to charge and collect the HST on their sales. If the HST collected is greater than the HST paid or payable, the difference is sent to the CRA. If the HST collected is less than the HST paid or payable, a refund can be claimed.


Step 2 - Do I need to apply for HST number

Do I need to apply for HST (Harmonized Sales Tax)? While it is not mandatory for most businesses to register and collect HST until 29 days following the single calendar quarter or four consecutive calendar quarters in which they first exceed worldwide sales of $30,000, we generally recommend that any business register as soon as possible.

Three reasons to apply and register:
1. Unless you are an HST registrant you cannot claim HST input tax credits (HST paid on business expenditures). If you are an HST registrant and your input tax credits exceed HST collected on sales, you may claim a refund of the excess from Canada Revenue Agency. If you're not a registrant the HST paid on expenses is included as part of the expense when computing net income.

2. Not being registered for HST tells everyone that you are running a truly small business. (Your sales are below $30,000 per year) If your customers are other businesses, they expect to pay HST.

3. Companies that are required to register for HST must remit the HST tax to Canada Revenue Agency - even if it has not been collected from the customer. By registering for HST upon starting your business you will eliminate the possibility of inadvertently surpassing the $30,000 threshold and being exposed to penalties and interest charges for noncompliance


Step 3 - Information required to apply for HST Number

Registration for the HST number is done by completing an application form that is then delivered directly to the appropriate government department.

Once your application is approved you would receive a letter via mail confirming your registration.

To apply for HST number in Ontario, you will need to provide:

  • Legal name and address of the Incorporated business
    or if it is a sole-proprietorship/partnership, then your full legal name
  • Description of the business activity
  • Your full name as listed on the SIN Card
  • Home address
  • Telephone number
  • Social Insurance Number
  • Date of Birth
  • Estimate of annual revenues from business activities.

If you have a partner, the same information would be required for your partner.
