CRA GST/HST Electrical Repair (Small Jobs), Outlet Replacement & Breaker Reset Contractor Audit — Montreal CPA Firm Near You: Defending Taxable Labour, Parts, Emergency Calls, Subcontractors & ITCs

A CRA GST/HST Electrical Small-Jobs Audit targets:
• electricians doing minor repairs
• outlet/switch replacements
• breaker reset & panel troubleshooting
• light-fixture replacement (legal, licensed work)
• GFCI outlet installation
• loose-wire fixes
• smoke detector replacement
• quick emergency electrician visits
• subcontract electrical helpers
Small-repair electricians are high-audit-risk because CRA sees repeated patterns of:
• cash/e-transfer micro-jobs
• emergency calls with no invoices
• unclear separation between labour and parts
• subcontract helpers not GST-registered
• ITCs claimed on personal tools or vehicles
• jobs too small to be “properly documented” — which CRA flags immediately
Mackisen CPA Montreal specializes in shielding electricians from these risks by applying correct GST/HST treatment, reconstructing invoices, validating subcontractors, and defending ITCs for tools, parts, safety equipment, and vehicles.
Legal Foundation
Excise Tax Act
s.165 — ALL electrical labour, troubleshooting, replacement & installation services are fully taxable
s.221 — mandatory GST/HST collection
s.169 — ITCs require proof and eligible documentation
s.141.01 — mixed-use allocation for tools/vehicles
Schedule IX — GST/HST based on property location
s.123(1) — defines “repair,” “installation,” “tangible personal property service”
Case Law & CRA Policy
ANY electrical repair = taxable
Emergency call = taxable
Travel/dispatch fees = taxable
Parts + labour packages = taxable
CGI v. Canada — place-of-supply is service location
Royal Bank v. Canada — incomplete invoices kill ITCs
Northwest Company Inc. — strict invoice requirements
Learning insight: There is no exemption — even a 5-minute breaker reset is a taxable service.
Why CRA Audits Small-Repair Electricians
Revenue Risks
• GST/HST not charged on small service jobs
• breaker reset/diagnostic fees called “quick help = no tax”
• e-transfer/cash jobs not invoiced
• emergency call-outs not recorded
• material fees (outlets, breakers, switches) not taxed
• travel charges missing GST
• multi-day troubleshooting not invoiced properly
• interprovincial (QC-ON) jobs misrated
• fixture-installation revenue underreported
Subcontractor Risks
• helpers without valid GST numbers
• subcontract labour paid cash
• invalid GST/HST registrations
• T4A exposure due to misclassification
• missing subcontract invoices
ITC Risks
• missing receipts for:
– outlets, switches, breakers
– wire, connectors, tape, GFCIs
– testers, meters, safety tools
– ladders, PPE
– vehicle gas & repairs
• imported tools missing self-assessment
• home-garage tool storage overclaimed
• personal tools claimed as business
Operational Risks
• no job logs
• WhatsApp/SMS repairs not invoiced
• inconsistent breaker/outlet purchase volumes
• dispatch/emergency records not matching deposits
• multi-unit building repairs underreported
• no before/after photos
High-risk operators:
one-man electricians
emergency electricians
subcontract helper crews
hybrid handyman-electricians
outlet/switch replacement specialists
Learning insight: CRA’s biggest suspicion: “Too many parts purchased for too little revenue reported.”

• verify subcontractor GST registration
• reconstruct ITC binder (tools, parts, PPE, vehicle)
• reconcile logs → invoices → deposits → GST filings

Common CRA Findings in Electrical-Repair Audits
• GST/HST not charged on “small fixes”
• helper/subcontractor invoices invalid
• ITCs denied due to lack of receipts
• imported tools missing GST
• deposits not included in GST periods
• parts usage indicates underreported jobs
• emergency call-outs unrecorded
• cash/e-transfer revenue not declared
Learning insight: CRA’s biggest reassessments come from material-to-job mismatches + unreported micro-jobs.
Real-World Results
• An emergency electrician avoided a $212,000 reassessment after Mackisen CPA rebuilt part-usage logs & subcontract records.
