How the calculation works
Adding tax. Multiply the price by the rate and add it: $1,000 × 13% = $130 HST, so the total is $1,130.
Removing tax. Divide the total by 1 plus the rate: $1,130 ÷ 1.13 = $1,000 before tax, and $130 is the HST inside it.
GST plus PST. Where both taxes apply, calculate each on the price before tax. For example, a $1,000 BC purchase subject to GST and PST has $50 GST plus $70 PST. Software-selection consulting without selling software, hardware or services to hardware is not subject to BC PST: if GST applies, its tax is $50. Quebec QST is 9.975% where applicable.
Rounding. Each tax is rounded to the nearest cent on its own, as CRA’s RC4022 guide says. CRA’s online calculator drops fractions of a cent instead, so totals can differ by a cent.
Do you need to charge GST/HST at all?
For most unregistered businesses, the $30,000 test decides when registration becomes mandatory. Already registered, or crossed the threshold earlier? Low sales now do not cancel that obligation. Taxi and commercial ride-share drivers register from their first taxable ride.
- Count worldwide taxable revenue before expenses from your businesses and associates. Exclude financial services, sales of capital property and goodwill from selling a business.
- Quarters start in January, April, July and October.
- Over $30,000 in one quarter: charge tax from the sale that crosses the threshold and register within 29 days of that sale. Across consecutive quarters: you remain a small supplier through the following month; register within 29 days of your first sale after that. A single-quarter crossing during that month can bring the obligation forward.

Questions people ask
Do I have to charge GST if I make less than $30,000?
Usually not if you are unregistered, have no earlier registration obligation and remain a small supplier. Existing registrants, including voluntary registrants, charge tax on applicable taxable sales even below $30,000. Taxi and commercial ride-share rules differ.
Is the $30,000 gross or net?
Use taxable revenue before expenses, including zero-rated sales and associated businesses. Exclude financial services, sales of capital property and goodwill from selling a business.
Can I charge HST without being registered?
Not having a number yet does not postpone tax that is already due. If you passed $30,000 in one quarter, charge GST/HST on the sale that crossed it and register within 29 days. A small supplier with no registration obligation should not collect it as GST/HST. See how to correct each case.
Do I need to put my HST number on an invoice?
Yes, on invoices of $100 or more, so your client can claim the tax back.
Does it cost anything to get a GST number?
No. Use CRA Business Registration Online (BRO). Telephone registration is no longer available. If BRO cannot handle your situation, follow CRA’s alternative-registration instructions, including RC1 where eligible; Quebec and non-residents have specific routes.
What’s the HST rate in Ontario?
