- CRA looks at your total annual taxable supplies — broadly, your revenue from sales subject to GST/HST — and places you into one of three reporting periods.
- Your assigned frequency is shown on your GST/HST registration confirmation and can also be checked through your CRA business account at any time.
- A registrant who qualifies for a longer reporting period — say, one CRA would otherwise place on annual filing — can elect to file more often instead, such as quarterly or monthly.
Once your Ontario business is registered to collect HST, CRA assigns you a reporting period — monthly, quarterly, or annual — that determines how often you file a return and remit whatever net tax you owe. Many business owners are surprised to learn this isn't a choice they made at registration; it's assigned based on how much revenue their business brings in, and it can change over time as revenue grows or shrinks.
Understanding how reporting periods work, and when you have room to choose a different one than CRA has assigned, helps you plan your cash flow and avoid the scramble of a missed filing.
How CRA Assigns Your Filing Frequency
CRA looks at your total annual taxable supplies — broadly, your revenue from sales subject to GST/HST — and places you into one of three reporting periods. Businesses with lower annual revenue are generally assigned to file annually, mid-range revenue typically means quarterly filing, and higher-revenue businesses are usually required to file monthly. The specific revenue bands CRA uses to draw these lines are set administratively and can be adjusted, so don't rely on a number you've seen in an old article or heard secondhand — check your CRA business account or your GST/HST notice of assessment to confirm your assigned frequency.
The Three Reporting Periods at a Glance
| Frequency | Who it typically applies to | What it means in practice |
|---|---|---|
| Annual | Smaller-revenue registrants (the default assignment unless you elect otherwise) | One return per year, though instalment payments may still be required during the year for some annual filers |
| Quarterly | Mid-range revenue registrants | Four returns per year, spreading remittance and filing work more evenly |
| Monthly | Higher-revenue registrants | Twelve returns per year, giving CRA more frequent visibility into larger tax amounts |
Your assigned frequency is shown on your GST/HST registration confirmation and can also be checked through your CRA business account at any time.
Can You Choose a Different Frequency Than the One CRA Assigns?
In many cases, yes. A registrant who qualifies for a longer reporting period — say, one CRA would otherwise place on annual filing — can elect to file more often instead, such as quarterly or monthly. What you generally cannot do is elect a longer period than the one your revenue actually qualifies you for; if your revenue puts you in the monthly bracket, you can't opt down to annual filing.
To change your elected frequency, you typically notify CRA through your business account or by the appropriate form, and the change takes effect from a future reporting period CRA specifies — not retroactively.
Why Some Businesses Elect to File More Often
- Smoother cash flow. Remitting smaller amounts more frequently can be easier to manage than one large annual payment.
- Faster access to refunds. If your input tax credits regularly exceed the HST you collect — common for businesses with large upfront costs — filing more often means recovering that refund sooner rather than waiting for an annual cycle.
- Better bookkeeping discipline. Monthly or quarterly filing forces more frequent reconciliation, which can catch errors earlier than an annual review would.
- Avoiding a large year-end surprise. Spreading remittances out can reduce the risk of a big, unexpected bill at year-end for a business whose revenue is growing quickly.
Staying on Top of Your Deadlines
Each reporting period carries its own filing and remittance deadline tied to how soon after the period ends CRA expects your return and payment. Annual filers generally get more lead time than monthly filers, but the exact deadline that applies to your specific frequency is set out on your GST/HST return package and in your CRA business account — confirm it there rather than assuming a generic date, since it can vary depending on your fiscal year-end and filer type.
Missing a deadline, even by a short margin, can trigger penalties and interest, so many businesses build a recurring calendar reminder tied to their specific reporting period rather than relying on memory.
Frequently asked questions
My revenue grew a lot this year — will CRA automatically move me to a shorter reporting period?
CRA periodically reviews registrants' reporting periods based on revenue, and your assigned frequency can change going forward. Watch for correspondence from CRA and check your business account rather than assuming your frequency stays fixed once your revenue crosses into a new bracket.
Can I switch back to a longer reporting period if my revenue drops?
It depends on whether your current revenue qualifies you for the longer period and on whether you elected your current frequency voluntarily or were assigned it. Confirm your options directly with CRA or a tax professional before assuming you can revert.
Do I still need to file a return for a period where I had no sales?
Generally yes — a nil return is still a return, and most registrants must file for every period in their assigned frequency even if there was no activity, unless CRA has specifically told you otherwise.
Is the deadline to pay HST always the same as the deadline to file the return?
Not necessarily for every filer type — some annual filers face a different payment deadline than their filing deadline. Check your specific return package rather than assuming the two always align.
