Frequently asked questions
When do I need to register for HST in Ontario?
Once your taxable revenue hits $30,000 in a single quarter or over four consecutive quarters, you have 29 days to register and start charging 13% HST. That $30,000 figure is CRA's small supplier threshold. You can also register voluntarily before you hit it — which often makes sense if you have big startup costs and want to claim back the HST you're paying on them.
What is the $30,000 small supplier threshold for HST registration?
It's the line CRA draws between optional and mandatory HST registration. If your total taxable revenue stays under $30,000 over four consecutive quarters, you're a small supplier and don't have to register. Go over $30,000 in a single quarter or across four rolling quarters, and registration is required. One thing people miss: the threshold is based on gross revenue, not profit. So expenses don't reduce the number.
How do I claim input tax credits (ITCs) on my HST return?
ITCs let you get back the HST you paid on business expenses — rent, software, supplies, vehicle costs, professional fees. To claim them, you need receipts or invoices that show the supplier's HST number and the tax amount. The expense has to be for your business, not personal. We track your ITCs during bookkeeping so nothing slips through when it's time to file.
What is the difference between GST and HST in Ontario?
In Ontario, you charge 13% HST — that's the 5% federal GST and the 8% Ontario portion rolled into one tax. You send the full amount to CRA, and they split it with the province. Some provinces like Alberta still use separate GST and PST. If you sell across provincial lines, place-of-supply rules decide which rate applies. We sort that out for you.
How often do I need to file my HST return — monthly, quarterly, or annually?
It depends on your annual revenue. Under $1.5 million — you file once a year. Between $1.5 million and $6 million — quarterly. Over $6 million — monthly. But here's the thing: you can choose to file more often than required. If you're racking up big ITCs, filing quarterly instead of annually gets you refunds faster. We figure out the best fit when we onboard you.
What are the penalties for filing HST late with the CRA?
CRA charges 1% of what you owe right away, plus another 0.25% for every full month you're late — up to 12 months. Interest piles on daily too. And if you've been late before, the penalties get steeper. If you're behind on multiple periods, we can catch you up, file for penalty relief where it applies, and set up reminders so it doesn't happen again.
