GST/HST Filing Deadlines for Toronto Business Owners

If you run a business in Toronto and are registered for the GST/HST, meeting the right filing and payment deadlines is essential to stay in good standing with the Canada Revenue Agency (CRA). The rules can vary depending on your reporting period, the structure of your business, and the amount of tax you collect. This article breaks down the key dates for 2026, explains the difference between filing and payment deadlines, and offers practical advice to help you avoid penalties.

Understanding Your Reporting Period

The CRA assigns your GST/HST reporting period based on the level of your annual taxable supplies. Most small businesses in Toronto will file either monthly, quarterly, or annually. Your reporting period determines when your returns and payments are due.

If your business has low sales, you are likely assigned an annual reporting period. For sole proprietors with a December 31 fiscal year‑end, the CRA sets a payment deadline of April 30 and a filing deadline of June 15. For incorporated businesses with a fiscal year‑end other than December 31, the return and any balance owing are due within three months after the end of the fiscal year.

Quarterly filers submit their returns one month after each calendar quarter ends. Monthly filers are required to file one month after the end of each month. The CRA may also require you to pay instalments if you owed more than $3,000 in GST/HST in the previous year.

Key Deadlines for 2026

The specific due dates for 2026 follow the standard rules. Remember, if a deadline falls on a Saturday, Sunday, or a statutory holiday, the CRA moves the due date to midnight of the next business day.

Monthly Filers

Monthly filers must file their return and make payment one month after the end of each reporting period. For example, the return for January 2026 would be due by February 28, 2026. All monthly returns are due on the same day as the payment.

Quarterly Filers

Quarterly filers have until one month after the quarter ends. The 2026 calendar for quarterly returns is as follows:

For quarterly filers, the payment deadline is the same day as the filing deadline.

Annual Filers

If you file annually and your fiscal year ends December 31, the CRA sets different dates for payment and filing:

• Payment deadline: April 30, 2026

• Filing deadline: June 15, 2026

For fiscal year‑ends other than December 31, both the return and any payment are due three months after the end of the fiscal year.

Instalment Due Dates

If you owed more than $3,000 in GST/HST in the previous year, the CRA may require you to pay instalments. The instalment due dates are:

• April 30

• July 31

• October 31

• January 31

These dates apply regardless of your reporting period. Missing an instalment can result in interest charges.

Payment Deadline vs Filing Deadline

A common source of confusion is the difference between the payment deadline and the filing deadline. For most businesses, both deadlines fall on the same day. However, for annual filers (especially sole proprietors with a December 31 year‑end), the payment is due earlier than the filing. The CRA requires you to pay any balance owing by April 30, but gives you until June 15 to file the return. Ensure you remit your payment on time even if you are still preparing the return, to avoid penalties and interest on the tax owing.

If you are a monthly or quarterly filer, the payment and filing deadlines are identical. It is still wise to double‑check your specific reporting period on your CRA account, because the dates are based on the period end, not the calendar month you file.

Penalties for Late Filing or Late Payment

The CRA imposes penalties and interest on late GST/HST returns and late payments. Any delay in filing can trigger a penalty, and interest accumulates on unpaid amounts until they are fully settled. In addition, if you are required to file electronically but submit a paper return, you will also be charged a penalty. Since 2024, all GST/HST registrants except charities and selected listed financial institutions must file electronically. Using CRA My Business Account, NETFILE, or compatible accounting software is the easiest way to stay compliant.

If you are unable to meet a deadline, the CRA may consider a penalty relief request in certain circumstances, but it is always better to file on time. Working with a Toronto accountant can help you manage the schedule and avoid costly mistakes.

How to File Your GST/HST Return

As noted, electronic filing is mandatory for almost all registrants. You can file using the CRA’s My Business Account portal, through NETFILE‑approved software, or via a representative authorized by the CRA. Filing electronically is usually faster, reduces errors, and gives you immediate confirmation. If you mail a paper return despite being required to file electronically, you will face a penalty.

Before filing, make sure you have accurate records of your sales, the GST/HST you collected, and any input tax credits you are claiming. The CRA may ask for supporting documents, so keep your books organized throughout the year.

Tips for Staying on Track

Toronto business owners can take a few simple steps to ensure they never miss a deadline:

• Mark all due dates on a calendar or set digital reminders well in advance.

• If you owed more than $3,000 in the previous year, plan to make instalment payments on the quarterly due dates.

• Reconcile your sales records monthly, even if you file quarterly or annually, to avoid surprises.

• Consider working with a professional accountant who can prepare and file your returns on time, especially if you have a complex business structure.

Frequently Asked Questions

What happens if I miss the GST/HST payment deadline?

If you miss the payment deadline, the CRA will start charging interest on the amount owing from the due date until it is paid in full. A late‑payment penalty may also apply. The penalty is calculated as a percentage of the balance due, so it is important to pay as soon as you realize you missed the date.

Can I change my GST/HST reporting period?

In some cases, yes. If your business’s taxable supplies change, you can request a different reporting period from the CRA. For example, a business that grows significantly may switch from annual to quarterly reporting. Contact the CRA or consult a tax professional to see if a change is appropriate for your situation.

Do I need to file a GST/HST return if I had no income in a period?

Yes. Even if you had no taxable sales or collected no GST/HST during a reporting period, you must still file a return. A nil return reports zero revenue and helps keep your account in good standing. Failing to file a nil return can still result in penalties for late filing.

What are the instalment due dates for 2026?

If you owed more than $3,000 in GST/HST in the previous year, you must make instalment payments by April 30, July 31, October 31, and January 31. These dates are the same each year. The CRA will notify you if you are required to pay by instalment.

Is the GST/HST filing deadline extended if it falls on a weekend?

Yes. If a filing or payment deadline falls on a Saturday, Sunday, or a statutory holiday, the deadline is moved to the next business day. Always check the CRA’s official calendar or your My Business Account for the exact adjusted date.
