GST/HST filing in Calgary

One tax, and where the risk goes instead

Alberta has no provincial sales tax (a nil provincial rate in the CRA’s table), so a business selling only in Alberta charges 5% GST: one registration, return and administrator, and no unrecoverable provincial tax in its costs. The tourism levy on accommodation is a specific charge, not a general sales tax.

That simplicity concentrates the risk. In Alberta there is effectively one review question, on the purchase side: can you support the input tax credits you claimed? With no provincial layer, the credit side is where a whole GST review lands. The position is tabled with its source on the Alberta tax facts page.

What an input tax credit actually requires

Money leaving the bank does not support a claim. The record must identify the supplier and, at the applicable thresholds, show its GST registration number. It must show the tax or enough to calculate it, and describe what was bought. A credit card statement with a merchant name and total meets none of those tests, and it is by far the most common claim disallowed on review.

Three more points recur. An unregistered supplier means no GST to claim, whatever the invoice says; registration numbers can be verified. Partly personal expenses allow only the business share, recorded at the time, not rebuilt under pressure. And a missed credit can often still be claimed within the window. See our note on what the CRA checks.

The complication arrives at the border

Alberta’s simplicity ends when you sell outward. The rate follows the place of supply, so a Calgary business selling into an HST province charges that province’s rate, not 5%. Selling into a province with its own sales tax raises the question of obligations there too. A business that expands nationally but keeps invoicing at 5% builds an under-collection on every affected invoice, and the seller, not the customer, owes the difference. The Sales tax for Canadian business annotates the guides on this.

What is covered

• GST registration, or review of your existing reporting period
• Returns prepared and filed on your assigned schedule
• Input tax credits claimed against documentation that supports them
• Supplier registration status confirmed where a claim depends on it
• Business and personal apportionment recorded at the time of claim
• Rates checked against place of supply for any sales made outside Alberta
• Returns reconciled to the ledger, and CRA correspondence handled
