Trades accountant and bookkeeping for Calgary contractors
Alberta gives trades firms simpler purchasing and a stricter payment clock than its neighbours. EverStone is a CPA for incorporated contractors and a Calgary small-business accountant, working remotely.
Quick answer: Trades companies in Calgary, Alberta pay no provincial sales tax on materials. They do file a separate provincial corporate return, carry WCB Alberta coverage obligations, and work to statutory payment deadlines running down the contracting chain. EverStone prepares the federal and Alberta corporate returns, GST filings and subtrade slips remotely. Published fees start at $325 a month for bookkeeping and $125 for a personal return.
Bookkeeping for tradesmen in Calgary is kept monthly, so the AT1 and the T2 come out of a reconciled file rather than a shoebox in March.

No provincial sales tax changes the purchasing side
Alberta has no provincial sales tax, removing a layer trades companies in British Columbia, Manitoba or Ontario can’t avoid. Materials carry GST only, fully recoverable by registrants through input tax credits, so it isn’t a cost buried in a Calgary bid.
Estimating is cleaner, with no judgement on whether a contract improves real property. Cash flow is smoother, because tax on large material orders comes back. But bidding in a PST or RST province means your estimating template stops being right.
Two corporate returns, not one
Alberta collects its own corporate income tax, so a corporation with a permanent establishment there files the federal T2 and a separate Alberta AT1. Companies new to the province often miss the AT1, because nothing in the federal filing prompts it.
Working across provincial lines also means allocating income among the jurisdictions with a permanent establishment, so where crews worked decides which government gets the tax.
The payment clock runs on a statutory schedule
Alberta’s construction lien law sets prompt payment timelines: an owner pays a contractor within 28 calendar days of a proper invoice, and the contractor pays each subcontractor within 7 calendar days of being paid.
An unpaid subcontractor past that deadline can start adjudication. Holding subtrade money after being paid is a defined, dated exposure, so payables should release subtrade payments against owner receipts. That is why the bookkeeping for tradesmen Calgary companies need matches subtrade payments to owner receipts every month, not at year-end.
WCB Alberta and the subtrade check
WCB Alberta administers coverage, and the logic is the same as elsewhere: pay a subtrade without confirming its account standing and the gap can become your liability. Tie confirmation to final payment and file it with the invoice. That also raises the classification question while it can still be answered, not after an undocumented season.
Subtrade slips and job costing
The federal T5018 obligation applies in Alberta as elsewhere: a business mainly in construction that pays others for construction services generally reports those payments. With multi-tier Calgary packages, the slips are only as good as the payables coding. Separating subtrade labour from materials and tagging both to jobs produces the slips, and shows which package made money. See the T5018 reporting guide.

What a trades business has to get right
| Item | Why it matters |
|---|---|
| Subcontractor payments | Construction payers report subcontractor payments to the CRA on a T5018 |
| Holdbacks | Amounts held back under a construction contract are recognized on their own timing, not when invoiced |
| Tools and equipment | Larger purchases are capitalized and depreciated rather than expensed in full |
| Vehicle use | A log separating business from personal kilometres is what supports the claim |
| Sales tax where you operate | 5% GST only. Alberta levies no provincial sales tax |
