Frequently asked questions

When is my GST/HST return due?
Monthly and quarterly filers: one month after the end of the reporting period. Annual filers: three months after the fiscal year-end — except sole proprietors with business income and a December 31 year-end, who file by June 15 and pay by April 30.
What if the due date falls on a weekend or holiday?
The CRA treats a return or payment as on time if it arrives on the next business day.
How do I know if I file monthly, quarterly or annually?
The CRA assigns it from your annual taxable sales: $1.5 million or less — annual; over $1.5 million up to $6 million — quarterly; over $6 million — monthly. You can choose to file more often.
Do I have to file online?
Yes, electronic filing is mandatory for almost all GST/HST registrants for reporting periods ending in 2024 or later. Charities and some financial institutions are exceptions.
