The BC PST Framework for Construction
British Columbia's PST system treats construction differently from most other transactions:
- Materials: 7% PST applies to building materials purchased by the contractor
- Labour on real property improvements: Generally exempt from PST
- Labour on tangible personal property: 7% PST applies
The critical question: Is this work a real property improvement or work on tangible personal property?
Real Property vs. Tangible Personal Property
Real Property Improvements (PST-exempt labour)
- Building construction, renovation, demolition
- Plumbing, electrical, HVAC installation in a building
- Landscaping and paving
- Installing fixtures that become part of the building
Tangible Personal Property (PST applies)
- Manufacturing or fabricating goods
- Repairing equipment that is not affixed to land
- Installing machinery that remains removable
The Grey Area: Affixed Machinery
Equipment that is permanently affixed to a building (bolted to floor, hard-wired into electrical system) can be treated as real property. Equipment that is merely resting on a surface or plugged in is tangible personal property.
BC PST Bulletin 027 and the related real property contractor bulletins provide detailed guidance on this classification.
Common Contractor Errors
1. Charging PST on full invoice (materials + labour)
Many contractors charge 7% PST on their entire invoice. For real property work, PST should only apply to materials (which the contractor typically already paid PST on when purchasing).
2. Misclassifying real property labour as TPP
HVAC installation labour in a building = real property improvement = no PST. But HVAC contractors often charge PST on everything.
3. Double taxation
When a contractor pays PST on materials and then charges PST on the full invoice including those materials, the end customer effectively pays PST twice on the materials component.
Recovery Opportunity
For companies with significant construction or renovation spending in BC, this is one of the largest recovery categories. Our Type 7 detector identifies invoices where:
- The vendor is classified as a contractor
- PST is charged on what appears to be real property labour
- The project description indicates real property work
Our Type 14 detector catches double taxation scenarios where PST appears on both the materials and the full contract amount.
