CRA GST/HST Gutter Cleaning, Eavestrough Repair & Downspout Maintenance Audit — Montreal CPA Firm Near You: Defending Taxable Labour, Seasonal Contracts, Subcontract Crews & ITCs

A CRA GST/HST Gutter Cleaning & Eavestrough Repair Audit targets:
• gutter cleaning companies
• eavestrough repair technicians
• downspout maintenance contractors
• fascia & soffit minor repair crews
• yearly gutter-maintenance subscription services
• leaf-guard installation teams
• subcontract ladder crews
• seasonal roof-edge cleaning providers
This industry is one of CRA’s major audit targets because it involves:
• 100% taxable property-maintenance services
• seasonal spikes (spring/fall)
• significant cash/e-transfer revenue
• subcontract support crews
• roof-height safety equipment ITCs
• multi-stage service bundles (cleaning + repair + guards)
• poor job-log documentation among small operators
Mackisen CPA Montreal specializes in defending gutter-maintenance contractors with GST/HST correction, subcontractor validation, and complete ITC reconstruction.
Legal Foundation
Excise Tax Act
s.165 — ALL gutter cleaning, downspout repair, fascia/soffit work & leaf-guard installation are fully taxable
s.221 — GST/HST must be collected
s.169 — ITCs require complete supporting documentation
s.141.01 — allocation for ladders, tools, vehicles & PPE
Schedule IX — GST/HST rate depends on property location
s.123(1) — defines “maintenance,” “repair,” “installation,” “real property service”
CRA & Case Law
Gutter cleaning = taxable
Downspout repairs = taxable
Leaf-guard installation = taxable
Roof-edge cleaning = taxable
Royal Bank v. Canada — incomplete invoices invalidate ITCs
Northwest Company Inc. — supplier invoices must meet legal requirements
Learning insight: There is no special exemption for gutter or roof-edge maintenance — every visit is taxable.
