Understanding GST/HST in Canada
Before diving into the filing process, it’s important to understand what GST/HST is and how it applies to businesses.
What is GST/HST?
- Goods and Services Tax (GST) is a federal tax applied to most goods and services in Canada.
- Harmonized Sales Tax (HST) is a combination of GST and provincial sales tax (PST) in provinces that have chosen to harmonize their tax systems.
Different provinces have different tax rates, so businesses must ensure they are charging and remitting the correct amount based on their location and customer base.
Who Needs to File GST/HST?
Not all businesses in Canada need to register for GST/HST. Here’s how to determine if you must file:
Mandatory Registration
You are required to register for GST/HST if:
- Your business earns more than $30,000 in taxable sales over four consecutive calendar quarter.
- You operate as a sole proprietor, partnership, corporation, or non-profit organization selling taxable goods or services.
- You provide taxable digital services to Canadian consumers as a non-resident business.
Voluntary Registration
Even if your business earns less than $30,000, you may still choose to register. The benefit of voluntary registration is that you can claim input tax credits (ITCs) on business expenses.

- Annual Filing – Businesses earning less than $1.5 million in taxable sales.
- Quarterly Filing – Businesses earning between $1.5 million and $6 million in taxable sales.
- Monthly Filing – Businesses earning over $6 million in taxable sales.
You can also choose to file more frequently to manage cash flow better and claim refunds sooner.
Step 2: Collect GST/HST from Customers
Businesses must charge the correct GST/HST rate based on the province where the sale occurs. Here are the current tax rates:
Province/Territory | GST/HST Rate |
---|---|
Alberta, Yukon, NWT, Nunavut | 5% (GST only) |
British Columbia | 5% GST + 7% PST |
Manitoba | 5% GST + 7% PST |
Ontario | 13% HST |
Quebec | 5% GST + 9.975% QST |
New Brunswick, Nova Scotia, PEI, Newfoundland & Labrador | 15% HST |
Saskatchewan | 5% GST + 6% PST |

As a registered business, you can claim ITCs to recover the GST/HST paid on business expenses. This includes:
- Office supplies
- Rent and utilities
- Business equipment
- Professional services (legal, accounting)
Keep detailed records and receipts of all eligible expenses to maximize your ITC claims.
Step 4: Calculate Your Net GST/HST
To determine how much you owe or will be refunded, use the following formula:
Total GST/HST Collected – Input Tax Credits (ITCs) = Net GST/HST Payable/Refundable
If your ITCs exceed the tax collected, you will receive a refund from the CRA.
Step 5: Submit Your GST/HST Return
You can file your GST/HST return through:
- CRA My Business Account (online)
- GST/HST NETFILE (electronic filing)
- Telephone filing (Telefile)
- Mail (paper filing)
Make sure to submit your return by the deadline based on your assigned filing frequency.
