CRA GST/HST Logistics & Warehousing Audit — Montreal CPA Firm Near You: Defending Storage Fees, Fulfillment Services, Cross-Docking & Interprovincial Flows

A CRA GST/HST Logistics & Warehousing Audit targets businesses involved in storage, fulfillment, inventory management, cross-docking, kitting, pick-and-pack operations, 3PL services, cold storage, distribution centers, and integrated logistics solutions.
This sector is one of CRA’s fastest-growing audit categories because logistics companies handle:
• taxable warehousing services,
• complex interprovincial shipments,
• foreign client inventories,
• zero-rating claims for exports,
• large facility ITCs,
• imported goods requiring self-assessment,
• drop-shipping structures,
• multi-party fulfillment, and
• supply-chain activities that CRA frequently misclassifies.
Mackisen CPA Montreal specializes in defending logistics & warehousing audits with complete supply-chain tax mapping, ITC defense, and CRA-ready documentation that protects companies from six-figure reassessments.
Legal Foundation
Excise Tax Act
s.165 — GST/HST applies to taxable warehousing & fulfillment services
s.169 — ITC documentation rules (invoices + proof of payment)
s.221 — requirement to charge and collect GST/HST
s.218/218.1 — self-assessment on imported goods & digital services
Schedule VI — zero-rating rules for export-related services
Schedule IX — place-of-supply rules for interprovincial shipments
s.142–143 — deeming rules for supplies performed inside/outside Canada
Case Law
Honeywell v. Canada — strict proof required for zero-rating
General Motors — classification of supplies must reflect economic reality
Royal Bank v. Canada — documentation must be complete
UPS/FedEx Cases — logistics charges follow primary supply tax status
Learning insight: CRA often misunderstands logistics operations — the defense must explain exactly what the service is and where the supply occurs.
Why CRA Audits Logistics & Warehousing Companies
CRA targets 3PLs and warehousing companies when it detects:
Revenue Risks
• storage fees not taxed correctly
• pick-pack/kitting classified incorrectly
• cross-dock fees missing GST/HST
• foreign clients treated as automatically zero-rated (often incorrect)
• fulfillment fees for e-commerce sellers not taxed properly
• intercompany location-fee structures unclear
Inventory & Shipping Risks
• in-and-out inventory flows not reconciled
• inventory shrinkage interpreted as unreported revenue
• missing proof for export shipments
• imported goods without correct self-assessment
ITC Risks
• large warehouse rent ITCs
• forklifts, conveyors, pallet systems, racks, cold-freezers
• cloud-based WMS (warehouse management software)
• utility & power bills
• invoices missing tax numbers
High-risk models:
3PL warehouses
cross-dock facilities
Amazon FBA prep centers
cold storage facilities
bonded warehouses
reverse-logistics centers
distribution hubs
freight consolidators
Learning insight: CRA presumes rate errors + missing GST on fees + invalid ITCs.
CRA Warehousing & Logistics Audit Process
CRA requests:
– storage & fulfillment contracts
– rate sheets
– inventory movement reports
– pick-pack logs
– shipping & receiving documents
– bills of lading (BOL) & PODs
– import (B3) & export documents
– invoices & proof of payment
– WMS system exports
– ITC worksheets
– GL & bank statementsCRA tests:
• correct GST/HST on warehousing, handling & fulfillment
• place-of-supply for shipping across provinces
• zero-rating eligibility for foreign customers
• validity of all ITCs
• whether drop-ship arrangements change tax responsibility
• whether shrinkage is properly documented
• whether freight or fulfillment is a standalone supply or part of a bundled supplyCRA issues a Proposed Audit Adjustment.
Mackisen CPA prepares a complete documentary + legal defense.
Learning insight: CRA uses transaction sampling, then extrapolates across thousands of warehouse movements — a single error can balloon into massive assessments.
Mackisen CPA’s Logistics & Warehousing Audit Defense Strategy
• build a Supply Chain Tax Map (inbound → storage → outbound)
• classify each revenue stream:
– warehousing
– fulfillment
– picking
– kitting
– cross-dock
– reverse logistics
– labeling
• prove zero-rating for foreign clients using proper documentation
• rebuild ITC binder for warehouse rent, equipment, utilities & software
• defend or correct self-assessments for imported goods
• reconcile WMS data with GST filings
• justify shrinkage with inventory logs
• prepare CRA-ready audit binder
• negotiate penalty/interest relief
Learning insight: Logistics audits are won by explaining what each service actually is and where it takes place.
Common CRA Findings in Logistics & Warehousing Audits
• GST/HST not charged on storage or handling
• zero-rated treatment applied incorrectly for foreign clients
• ITCs denied for missing/invalid invoices
• imported goods missing self-assessment
• inventory shrinkage categorized as unreported revenue
• cross-dock services misunderstood
• bundled fulfillment packages taxed incorrectly
• intercompany transactions lacking GST/HST
• shipping documents missing (BOL/POD)
Learning insight: CRA’s biggest adjustments arise from zero-rating, ITCs, and storage-fee misclassification.
Real-World Results

• A cold-storage facility reversed a $420,000 ITC denial by providing complete equipment & utility invoices.
• An FBA prep center eliminated penalties after we mapped service categories and corrected GST/HST on fulfillment fees.
