Calgary Sellers: Keep the Evidence for Out-of-province Sales Tax

Classify the transaction before the province

Goods, general services and services with special location rules can follow different analyses. CRA's place-of-supply guidance considers delivery for goods and, for many services, the recipient's relevant address. Special rules can override the general approach.

This is why a checkout setting based only on the seller's address is unreliable. It is also why an out-of-province billing address should be treated as information to review rather than an automatic instruction for every type of service.

Illustrative example: a consultancy and a shipped product

A Calgary marketing consultant performs a general service for a customer whose only relevant Canadian business address, obtained in the normal course of business, is in Ontario. Assuming the general rule applies and the supply is taxable, the Ontario place of supply produces 13% HST. A $2,000 fee would therefore carry $260 HST.

Separately, a Calgary retailer ships a taxable $400 product to an Ontario delivery address under the stated delivery arrangement. Assuming Ontario is the place of supply, the HST is $52. The examples reach the same province through different facts; neither establishes a rule for every Calgary engagement or sale.

Make the tax evidence part of the order file

Keep the customer identity, relevant addresses, delivery terms, product or service description and contract. Document the approved tax treatment for recurring transaction types. When the facts change, route the exception for review rather than copying the old invoice setting.

Reconcile the tax amounts by transaction and credit note to the ledger. Refunds can relate to sales from an earlier period or a different destination, so a general refund account may conceal the necessary adjustment. Retain the original order and the reason for the change.

Review obligations beyond the example

An Alberta business can encounter provincial sales taxes, marketplace rules, registration questions and export conditions outside this basic GST/HST comparison. Selling from Calgary does not resolve all of those obligations, and selling to a foreign customer does not by itself prove zero-rating.

The practical first step is a clean transaction report grouped by product or service, destination and sales channel. That evidence lets the responsible adviser assess obligations efficiently and gives the bookkeeper a documented basis for the recurring tax codes.
