CRA GST/HST Landscaping Maintenance, Lawn Care & Gardening Services Audit — Montreal CPA Firm Near You: Defending Taxable Labour, Seasonal Contracts, Subcontractors & ITCs

A CRA GST/HST Landscaping Maintenance & Lawn Care Audit targets:
• lawn maintenance companies
• residential & commercial landscaping teams
• grass cutting & trimming crews
• spring/fall clean-up services
• hedge trimming & shrub maintenance
• garden bed planting & upkeep
• mulch/soil delivery & installation
• leaf removal services
• fertilization & seeding
• weekly/seasonal landscape contracts
• subcontract garden/lawn workers
This sector is heavily audited due to:
• 100% taxable services
• seasonal spikes (spring/summer/fall)
• cash/e-transfer payments
• subcontractor-heavy labour model
• large equipment & supply ITCs
• poor recordkeeping among small landscape operators
Mackisen CPA Montreal specializes in protecting landscaping & lawn-care contractors through job-log reconstruction, GST/HST correction, subcontractor verification and ITC defense.
Legal Foundation
Excise Tax Act
s.165 — ALL lawn care, landscaping, planting, garden maintenance, soil/mulch installation & cleanup services are fully taxable
s.221 — GST/HST must be collected on every service
s.169 — ITCs allowed only with full documentary evidence
s.141.01 — mixed-use equipment allocation (mowers, trimmers, trailers, tools)
Schedule IX — GST/HST rate depends on property location
s.123(1) — defines “maintenance,” “installation,” “real property service”
Case Law & CRA Rulings
Yard maintenance = fully taxable
Lawn mowing = taxable
Garden upkeep = taxable
Fertilization/seeding = taxable
Royal Bank v. Canada — missing invoice details = ITC denial
Northwest Company Inc. — supplier invoice requirements strict
Learning insight: NO gardening or landscaping maintenance service is exempt.
