A Saskatoon contractor applied out-of-province rules to real-property contracts. We corrected the treatment and settled a $19,000 exposure.
Saskatchewan applies provincial sales tax to a broader range of services and construction contracts than most provinces, and this contractor had been applying an out-of-province approach to real-property work. We reviewed each contract type against the Saskatchewan rules, determined where the contractor was the consumer of materials rather than a reseller, corrected the filings, and settled roughly $19,000 of exposure without penalty escalation.
Construction files carry subcontractor reporting, holdbacks and heavy equipment, and the CRA cross-checks the payment chain automatically.
British Columbia, Saskatchewan and Manitoba run their own sales taxes alongside GST, filed separately, and unlike GST they are generally not recoverable as input credits.
Why it bites: Businesses expanding into a PST province routinely register late, and the province assesses from the date the obligation started, not the date of registration.
