GST/HST filing in Fort McMurray

One tax, and where the risk goes instead

Alberta is the outlier. There is no provincial sales tax, which the CRA’s own rate table records as a provincial rate of nil. A Fort McMurray business selling only within Alberta charges 5% GST and nothing else, with one registration, one return and no non-recoverable provincial tax buried in its costs. Alberta does levy a separate tourism levy on accommodation, which matters to hotels, lodges and short-term rentals, but that is a specific charge rather than a general sales tax.

That simplicity concentrates the exposure. In a two-tax province a review can go wrong in several directions. In Alberta there is effectively one question, and it sits on the purchase side: can you support the input tax credits you claimed? The position is tabled with its source on the Alberta tax facts page.

Why Fort McMurray contractors so often file refund returns

A site-services or equipment business in Wood Buffalo can spend a large share of its revenue on GST-bearing inputs: fuel, tires, parts, equipment purchases and rentals, shop supplies, subcontractors, accommodation and travel for crews. In a period with a major equipment purchase or a slow billing month, the credits can exceed the GST collected, and the return becomes a refund claim. Refund returns, especially large or unusual ones, are the returns most likely to be held for review before the money is released.

That is not a reason to avoid claiming credits you are entitled to. It is a reason to file each return as if the review is coming: invoices organized by period, large purchases supported by the purchase agreement and the supplier’s GST number, and a short reconciliation of the return to the ledger. When the CRA does ask, a review that takes a week instead of three months is mostly a matter of how the records were kept. Our note on what the CRA checks covers the ground in more detail.

What an input tax credit actually requires

A claim is not supported by the fact that money left the bank. The documentation has to identify the supplier and, at the applicable thresholds, carry the supplier’s GST registration number. It has to show the amount of tax or enough information to calculate it, and it has to describe the supply well enough that someone else can tell what was bought. A fuel-card summary or a credit card statement showing a merchant and a total meets none of those tests, and it is by far the most common category of claim disallowed on review.

Three further points recur in Wood Buffalo files. Where a supplier is not registered, there is no GST to claim regardless of what the invoice says, and registration numbers can be verified. Where a truck or a phone is used partly for personal purposes, only the business share is claimable, and the split should be recorded when the claim is made. And credits do not have to be claimed in the period the tax was paid: there is a window, so a missed credit found in time is often still recoverable.

Rent, camps and mixed supplies

Property is a frequent source of confusion here. Commercial rent — a shop, a yard, an office, a laydown area — is generally taxable, so a GST-registered landlord charges GST and a registered tenant claims it back. Long-term residential rent is generally exempt, so a landlord renting a house to people working in the region does not charge GST and cannot claim credits on the costs of that rental. Short-term accommodation is different again. A company providing both accommodation and meals, or both equipment and an operator, has to decide whether it is making one supply or two, because the answer changes how the GST is calculated.

Sales to First Nations and on reserve

The municipality lists several Indigenous communities within Wood Buffalo, and some businesses supply goods or services to bands, band-empowered entities or status Indians on reserve. GST relief can apply to certain of those supplies under specific conditions, but it depends on who the customer is, what is supplied and where it is delivered, and it has to be documented on each transaction. Applying relief without the supporting evidence leaves the supplier owing the tax. We set up the documentation process before the first invoice rather than after a review.

The complication arrives at the border

Alberta’s simplicity ends when you sell outward. The rate follows the place of supply rather than your address, so a Fort McMurray business delivering goods or services into a harmonized province charges that province’s rate, not 5%. Work into a province with its own separate provincial sales tax can create a registration obligation there too. A contractor that sends a crew to Saskatchewan or British Columbia between local seasons, or ships equipment out for a job, should settle the registration position before mobilizing. The sales tax hub annotates the guides that cover this.

Registration, reporting periods and the small supplier threshold

A business with taxable supplies above the $30,000 small-supplier threshold must register. Many contractors register earlier anyway, because operators and prime contractors expect a GST number on every invoice and because registration is what allows credits to be claimed on start-up equipment. Once registered, the CRA assigns a reporting period — monthly, quarterly or annual — based on revenue, and some businesses choose to file more often. A business that regularly files refunds may prefer monthly filing to get its cash back sooner. Returns are filed electronically through My Business Account or filing software; form GST34 is the paper equivalent. Changing your filing frequency explains the election.

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
• Refund returns filed with the support a review will ask for
• Rent, accommodation and mixed-supply treatment reviewed
• Rates checked against place of supply for any work outside Alberta
• Returns reconciled to the ledger, and CRA correspondence handled

Remote, and there is no Fort McMurray office

EverStone is a fully virtual, one-CPA firm. There is no Fort McMurray office and no Alberta location. Businesses are served entirely online: records arrive through secure exchange, returns are reviewed by email or a short video call, and filings are approved by e-signature. One accountant holds the file, which keeps the documentation standard consistent from one period to the next instead of tightening only after a question is asked.
