Quarterly vs. Annual HST Filing: Which Should Your Business Choose? (2026)

If your business makes $1.5 million or less in taxable sales a year, the CRA assigns you annual HST filing, and you can choose quarterly instead. Annual means one return a year, but once your net tax reaches $3,000 you may still have to pay in quarterly instalments. Quarterly means four returns, each one smaller and based on what you actually collected. Pick quarterly if you usually get HST back or your sales swing a lot. Pick annual if you usually owe a steady amount and your books stay current.

How does the CRA assign your HST reporting period?

The CRA sets your reporting period from your annual taxable supplies, which for most small businesses means taxable sales (CRA: make changes to your GST/HST account, rules current for 2026, accessed October 3, 2026):

Two rules on that page catch people out. First, moving to a more frequent period is easy, and moving back is not: you can elect a less frequent period only if, after 12 months, your taxable supplies fall below the threshold for your assigned period. Second, the CRA will not adjust your period for you when your sales drop. If you want the change, you have to ask for it.

Almost every owner-run business in Guelph and the surrounding area sits in the first row. So the real choice is annual or quarterly.

Does annual filing mean you only pay HST once a year?

Not always. If you file annually and your net tax for the previous fiscal year was $3,000 or more, you may have to make quarterly instalment payments during the current year (CRA: find out if you need to pay by instalments, accessed October 3, 2026). The $3,000 covers the whole business, including every branch and division. Net tax is the HST you collected minus the input tax credits you claim for HST paid on business expenses (CRA: instructions for preparing a GST/HST return, accessed October 3, 2026), so a business that collects $3,000 more than it claims back over a year is already there.

Instalments are due within one month after the end of each fiscal quarter (CRA: when to pay instalments, accessed October 3, 2026). With a December 31 year end, the remaining dates for the 2026 fiscal year are:

The dates move because when a due date falls on a Saturday, Sunday or CRA-recognized public holiday, the payment is on time if the CRA receives it, or it is postmarked, by the next business day (same CRA page).

Each instalment is usually one quarter of last year's net tax. You can base them on an estimate of this year instead if you expect to owe less. The risk is on you: if your estimate comes in short, the CRA charges instalment interest on the difference (CRA: calculate your instalment payments, accessed October 3, 2026). In your first year of registration, the CRA annualizes a short year to decide whether instalments start in year two.

So an annual filer with a steady HST bill often ends up paying four times a year anyway. The difference is that the payments come from last year's numbers, while a quarterly filer pays on what each quarter actually brought in.

When are annual and quarterly HST returns due?

The filing calendars differ too (CRA: reporting requirements and deadlines, accessed October 3, 2026):

For an annual filer with a December 31, 2026 year end, the 2026 return is due March 31, 2027. A sole proprietor with business income gets more time to file, until June 15, 2027, but the money is still due April 30, 2027. Our 2026 HST filing deadlines guide has the full quarterly calendar.

When is quarterly HST filing the better choice?

You usually get HST back. If you pay more HST on business costs than you charge your customers, you claim the difference as a refund on your return (same CRA instructions page). An annual filer can claim it once a year. A quarterly filer claims it four times a year. This is common for new businesses spending on setup and for businesses that bought equipment or vehicles this year.

Your sales are growing or swing by season. Instalments follow last year. If this year is very different, an annual filer either overpays through the year or meets a large balance at year end. Quarterly filing keeps each payment tied to real sales.

You want the discipline. Four returns means four times a year your books have to be reconciled well enough to file. Errors get caught within a few months instead of surfacing at year end.

When is annual HST filing the better choice?

You owe a modest, steady amount. If your net tax stays under $3,000, you file once and pay once. That is the simplest position available.

Your revenue is stable and your books are current. Instalments based on last year will be close to right, and the year-end return holds no surprise.

You want fewer deadlines. One return a year means one filing to prepare, though you still have to put the HST you collect aside as you go.

The trap with annual filing is the cash. HST you collect in February is not yours, but on an annual schedule it sits in your account for a year or more. Businesses that spend it end up borrowing to pay it in the spring.

How do you change your HST reporting period?

If you are assigned annual and want quarterly, file an election (CRA: make changes to your GST/HST account, accessed October 3, 2026):

• Online: through My Business Account, or Represent a Client if your bookkeeper handles it for you.
• By mail: fill out Form GST20, Election for GST/HST Reporting Period, and send it to your tax centre.

The CRA pages we checked do not say in plain terms when an election takes effect. Confirm the start date with the CRA when you file, and keep paying on your current schedule until the change shows in your account. Remember the one-way door: going back to annual later depends on the 12-month rule above.

What matters more than filing frequency?

Whether you know your number. A business with reconciled books handles either schedule without stress, because the HST owing is a figure it already has. A business with messy books finds every schedule stressful, because someone has to rebuild the number before each deadline. Moving from annual to quarterly will not fix messy books. It will make you rebuild them four times a year.

Intersect's HST filing service keeps your books current every month, so the return is a review rather than a rebuild, whichever schedule you are on. If you are not sure your books are there yet, the bookkeeping health check is a quick way to find out, and what a bookkeeper costs in Ontario lays out the numbers.

Frequently asked questions

Can I switch from annual to quarterly HST filing?

Yes. A business assigned an annual reporting period can elect to file quarterly or monthly instead. You make the election online in My Business Account or Represent a Client, or by mailing Form GST20 to your tax centre.

Can I switch from quarterly back to annual?

Only in limited cases. If the CRA assigned you a quarterly or monthly period, you can elect a less frequent one only if, after 12 months, your taxable supplies fall below the threshold for your assigned period. The CRA does not move you back on its own.

If I file HST annually, do I still pay quarterly?

You may have to. An annual filer whose net tax for the previous fiscal year was $3,000 or more may have to make quarterly instalment payments, each due within one month after the end of a fiscal quarter.

Does quarterly filing get my HST refund sooner?

You claim a refund on a return, so a business that regularly pays more HST than it collects can claim four times a year as a quarterly filer instead of once as an annual filer.
