What Is HST and Who Needs to File in Ontario
The Harmonized Sales Tax (HST) is a value-added tax applied to goods and services in Ontario. Businesses with annual taxable revenues exceeding $30,000 must register for the GST/HST program and charge HST on the goods and services they sell.
You’ll then need to file regular HST returns to report and remit the tax collected.
How Often Do You Need to File HST in Ontario?
Before you file your GST/HST return, it’s important to know when and how often you need to do so. HST reporting periods vary based on your business’s revenue. Businesses are generally assigned monthly, quarterly, or annual reporting periods depending on their taxable revenue in the previous fiscal year.
If your business made more than $30,000 in taxable revenue, you'll be required to file on a monthly or quarterly basis. If your revenue is below this threshold, you may qualify to file annually.
It’s important to know which reporting period applies to your business to avoid missing your HST return due date and potentially facing penalties.
What is the HST Return Due Date in Ontario?
The HST return due date depends on your reporting period:
- Monthly filers: Your return is due on the 20th of the following month.
- Quarterly filers: Your return is due on the 20th of the month following the end of each quarter.
- Annual filers: Your return is due on June 15th of the following year, but any amount owing is due by April 30th.
It’s important to note that late filing penalties apply if you miss your HST return deadline. To avoid these penalties, ensure you file on time.

2. Enter your GST/HST access code and Business Number.
3. Select the reporting period and other required information.
4. If applicable, check the box for a nil return if you have no taxes to report for the period.

Once submitted, you’ll receive a 6-digit confirmation number, which confirms that your return has been filed.
3. File Through Your Bank (If Eligible)
However, not all financial institutions provide this service, so it’s important to check with your bank first. If available, this method may offer added convenience for businesses that already handle their finances through online banking.
4. File HST with Accounting Software (e.g., QuickBooks, Xero)
To file using third-party software:
1. Ensure your accounting software is compatible with the CRA’s Internet File Transfer system.
2. Prepare your GST/HST return within the software.

This method is especially useful for businesses that have complex accounting needs or that need to submit multiple returns.

2. Follow the instructions to enter your business information.
3. Confirm the information and submit your return.
6. File HST by Mail (Paper Return)
However, be mindful that filing by mail can lead to delays and potential penalties if your return is late. Unless absolutely necessary, filing electronically is the preferred method.
How to Pay Your HST to CRA After Filing
Once your HST return is filed, you may need to make a payment to the CRA. There are several HST payment methods available:
- Online: You can pay via My Business Account or through online banking services.
- Bank: Visit your bank to pay in person through a pre-authorized payment or bill payment option.
- Mail: You can mail a cheque along with your return.
- Phone: Some financial institutions allow payments by phone.
Make sure to pay your HST on time to avoid interest and penalties.
What If You Need to Amend Your HST Return?
If you realize that you’ve made an error on your HST return, you can amend your return by filing a correction with the CRA. This can be done online through My Business Account or by mailing an amended return.
Be sure to keep track of any changes in your input tax credits (ITCs), sales, or other reportable amounts.
What If You Have a Nil Return?
If your business had no taxable sales or GST/HST to report during a given period, you can file a nil return. Filing a nil return is still important because it keeps your account up to date with the CRA and prevents penalties for failing to file.
