GST/HST Filing in Canada: What Small Businesses Need to Know
Understand how sales tax reporting works and stay ahead of CRA deadlines
Goods and Services Tax (GST) and Harmonized Sales Tax (HST) are a vital part of running a business in Canada. Whether you’re just starting your small business or scaling up, understanding your tax obligations with the Canada Revenue Agency (CRA) is essential to staying compliant and avoiding costly penalties. This article provides an overview of GST/HST filing in Canada, including who needs to register, how to report, important deadlines, and how Cloud Edge Accounting can simplify the process for you.
What is GST/HST?
In Canada, GST is a federal tax of 5% applied to most goods and services. In some provinces, GST is combined with the provincial sales tax (PST) into a single Harmonized Sales Tax (HST). The HST rates vary by province:
| Province | HST Rate |
| Ontario | 13% |
| Nova Scotia | 15% |
| New Brunswick | 15% |
| Newfoundland and Labrador | 15% |
| Prince Edward Island | 15% |
In provinces not using HST, businesses may need to collect GST and possibly a separate PST or Quebec Sales Tax (QST).
Do You Need to Register for GST/HST?
Small businesses must register for a GST/HST number if their total taxable revenues exceed $30,000 over four consecutive calendar quarters. This includes revenue from sales, commissions, and most other business income.
If you’re under the threshold, registration is optional. However, voluntarily registering can allow you to claim input tax credits (ITCs) on business purchases.
Key situations that require GST/HST registration:
- You exceed $30,000 in gross taxable revenue in four consecutive quarters
- You operate a taxi or ride-share service (must register regardless of income)
- You’re a non-resident doing business in Canada
Filing Frequency Options
The CRA assigns your filing frequency based on your annual taxable revenues:
| Revenue Threshold | Filing Frequency |
| $1.5M or less | Annually (default) |
| $1.5M – $6M | Quarterly |
| Over $6M | Monthly |
You can request more frequent filing if it helps your cash flow, but you must stick with the CRA’s assigned minimum.
How to File GST/HST Returns
- Collect GST/HST from sales: Charge the correct rate based on your customer’s location.
- Track Input Tax Credits (ITCs): Save receipts for business expenses where GST/HST was paid.
- Calculate net tax: GST/HST collected – ITCs = amount to remit (or refund).
- File return: File online through CRA My Business Account or with your accounting software.
- Pay CRA: Pay the amount due by the deadline to avoid interest and penalties.
Important Filing Deadlines
Deadlines depend on your assigned filing frequency:
- Annual (individuals): File by June 15, payment due by April 30
- Annual (corporations): File and payment due within 3 months after GST period end
- Quarterly: File and payment due within one month after GST period end
- Monthly: File and payment due within one month after GST period end
If your due date falls on a weekend or public holiday, CRA will accept your return on the next business day.
Common GST/HST Filing Mistakes to Avoid
- Missing deadlines: Late filings result in penalties and interest.
- Not charging the correct rate: Know your customer’s province and apply the correct GST or HST.
- Ignoring ITCs: You can reduce the amount you owe by claiming credits on business purchases.
- Mixing personal and business expenses: Keep transactions separate to avoid audit issues.
