Updated Checked by the Tax-Services.ca editorial team How we check
To record GST/HST in your bookkeeping, keep the tax out of your revenue and expenses and post it to its own accounts. Tax you charge goes to a GST/HST payable account, and tax you pay on business purchases goes to a receivable account, so the difference is what you send in.
What goes into the two GST/HST accounts?
Set up two accounts before you post a single invoice. One holds the tax you collect from customers. The other holds the tax you pay to suppliers, which the CRA calls input tax credits (ITCs). You claim those on line 106 of your return.
Take a $2,000 sale in Ontario. HST at 13% is $260, so the customer owes $2,260. Your revenue is $2,000, not $2,260. The other $260 isn’t yours, and treating it as income means you’d pay income tax on money you’re only holding for the CRA.
If the sale were in Alberta, the tax would be 5% GST, or $100. Same entries, smaller number. The GST/HST calculator gives the tax for any province or territory.
How the journal entries look
| Event | Debit | Credit |
|---|---|---|
| Sale of $2,000 plus 13% HST | Accounts receivable $2,260 | Sales $2,000, HST payable $260 |
| Purchase of $800 plus 13% HST | Expense $800, HST recoverable $104 | Accounts payable $904 |
| Filing: net tax of $156 paid | HST payable $260 | HST recoverable $104, bank $156 |
After the filing entry both tax accounts are back at zero. That’s your check. If a balance is left over, a sale or purchase was posted without its tax, or the wrong rate was used.
Rates to code into your software
| Where you sell | Tax charged |
|---|---|
| Ontario | 13% HST |
| New Brunswick, Newfoundland and Labrador, PEI | 15% HST |
| Nova Scotia (from 1 April 2025) | 14% HST |
| Alberta, Yukon, Northwest Territories, Nunavut | 5% GST |
| British Columbia | 5% GST plus 7% PST |
| Saskatchewan | 5% GST plus 6% PST |
Quebec and Manitoba have their own provincial taxes, and we haven’t confirmed their 2026 rates against the provincial pages, so check those first. PST is a provincial tax, so post it to a separate account. Never fold it into HST payable.
Which records does the CRA want for an ITC?
You can’t claim an ITC on a receipt that lacks the basics, and the amount decides how much detail you need.
- Under $100: the supplier’s name and the date.
- $100 to $499.99: add the GST/HST amount and the supplier’s registration number.
- $500 and over: add your own name, a description of what you bought and the payment terms.
Most registrants have four years from the end of the reporting period to claim an ITC. That’s a long time, but don’t lean on it. Missing receipts are much harder to find after a year.
Do you have to register at all?
Not always. You’re a small supplier if your worldwide taxable revenue is $30,000 or less in a single calendar quarter and across the last four quarters. Small suppliers don’t have to register, but they can do so voluntarily, which lets them claim ITCs. Once you register, you deduct ITCs from the tax you charged to find your net tax. Your filing period depends on annual taxable sales: annual at $1,500,000 or less, quarterly above that up to $6,000,000, and monthly beyond.
A backwards question comes up often. What if you only have a tax-included price of $565? The HST reverse calculator splits it into $500 and $65 of HST, which is what you post. For British Columbia sales, the GST and PST calculator shows the two taxes side by side, though it applies 12% to everything, so it will overstate the tax on items that are exempt from one of them.
Mistakes that cost money
- Recording revenue with the tax included, then paying tax twice.
- Claiming ITCs on personal spending, club memberships or exempt supplies, which the CRA doesn’t allow.
- Treating zero-rated sales like exempt ones. On zero-rated sales such as basic groceries and most exports you charge 0% and can still claim ITCs. On exempt sales you generally can’t.
- Mixing BC or Saskatchewan PST into the GST account.
None of this replaces a bookkeeper’s judgement on unusual items like meals, vehicles or property sales. It gives you a routine you can repeat every month, and that habit is what keeps a return simple when the filing date arrives and the receipts are all in one place.
Where the numbers come from
The $30,000 limit, reporting periods, record thresholds and ITC time limit come from Canada Revenue Agency publications, read on 30 September 2026. Rates come from the CRA rate table and the provincial finance pages. This site has no link to the CRA or any government.
Frequently asked questions
Is GST/HST revenue?
No. Tax you collect is money owed to the CRA, so post it to a payable account and keep revenue at the pre-tax price.
Which account holds tax I pay on purchases?
A receivable or recoverable account. It is your input tax credit, claimed on line 106 of the return.
What records support an ITC over $500?
The supplier's name and number, the GST/HST amount, your name, a description of the goods and the payment terms.
Do I have to register for GST/HST?
Not if your taxable revenue is $30,000 or less in a quarter and over the last four quarters. You can register voluntarily.
How long do I have to claim an ITC?
Most registrants have four years from the end of the reporting period in which the credit first became available.
