Filing and Remitting GST/HST Returns in Canada: Frequencies and Deadlines
A South African setting up a small consulting business in Alberta charges a flat 5% GST. Register the same kind of business in Ontario and the rate is 13% HST. Register in Nova Scotia and it’s 14%. The rate itself is province-specific — but filing and remitting GST/HST returns in Canada runs through one federal system, CRA, regardless of which province you’re registered in.
Why your filing frequency isn’t fixed
The honest answer to how often do I have to file a GST/HST return is: it depends. CRA assigns a filing frequency — generally annual, quarterly, or monthly — based mainly on how much taxable revenue your business brings in. A small consultancy just getting started typically lands on the least frequent option available to it; a larger, higher-turnover business gets filed more often. Cape2Canada’s research doesn’t hold verified, current revenue thresholds for exactly where those lines sit, and they’re the kind of figure CRA adjusts — check the current bands directly on CRA’s site before assuming a frequency, rather than guessing from an old blog post.
The quick method, briefly
New registrants often ask what is the quick method of accounting for GST — in plain terms, a simplified way of calculating what you remit, aimed at smaller registrants who’d rather apply a set remittance rate to their sales than track input tax credits on every purchase in detail. It trades some precision for simplicity — worth asking a Canadian accountant whether it suits your specific business, since the right answer depends on how much GST/HST-bearing expense you actually carry.
When payment is actually due
Your filing frequency sets your deadline: an annual filer typically has longer after their fiscal year-end than a quarterly or monthly filer does after each period closes. The specific number of days is a CRA rule this piece won’t state without a confirmed current figure — but the pattern worth remembering is that the filing deadline and the payment deadline usually land on the same date, so treat them as one obligation, not two separate ones with different clocks.
What happens if you’re late
Filing or remitting late generally triggers CRA penalties and interest on the amount owing, calculated from the due date rather than from when CRA eventually notices. The practical newcomer mistake is treating GST/HST like a South African VAT return handled through a single familiar system — assuming the deadline is flexible because “it’s just a formality” is exactly the assumption that costs money here. CRA does not treat it as a formality.
Changing your frequency
A registrant can generally ask CRA to move to a more frequent filing schedule voluntarily — useful if, for example, your business regularly runs input tax credits ahead of what it collects and you’d rather get refunds sooner than wait for an annual cycle to close. Moving to a less frequent schedule than CRA assigned is more restricted and depends on your revenue staying under the relevant threshold.
None of this replaces an accountant who can look at your actual numbers and province. Cape2Canada’s What It Really Costs guide covers the broader budget picture around starting work in Canada, of which business tax filing is one recurring piece.
