CRA GST/HST IT Consulting, Software Implementation & Tech Support Audit — Montreal CPA Firm Near You: Defending Service Classification, Subcontractors, Imported Software & ITCs

A CRA GST/HST IT Consulting & Tech Support Audit targets businesses offering:

• IT consulting
• software implementation
• cloud migration
• cybersecurity services
• helpdesk & tech support
• systems integration
• digital transformation services
• project management & IT architecture
• managed IT services (MSP)
• data recovery & networking

The IT consulting sector is highly audited due to:

• mixed taxable services
• imported SaaS tools requiring s.218 self-assessment
• subcontracted developers & consultants
• multi-province client base
• inconsistent GST/HST application on remote services
• bundled deliverables (consulting + software + support)
• large recurring ITCs
• multiple revenue streams (MSP, hourly, project, retainers)

Mackisen CPA Montreal specializes in defending IT consultants by mapping each supply, correcting tax rates, rebuilding ITC documentation, and preparing CRA-standard audit binders.

Legal Foundation

Excise Tax Act

• s.165 — GST/HST applies to all IT consulting & tech support

• Schedule IX — place-of-supply rules for interprovincial clients

• s.221 — mandatory GST/HST collection

• s.169 — ITC eligibility & documentation requirements

• s.141.01 — mixed-use allocation rules

• s.218 & 218.1 — self-assessment on imported software/SaaS

• s.123(1) — definitions for “service,” “intangible,” “digital supply”

Case Law & CRA Guidance

• Honeywell — zero-rating must be proven

• City of Calgary v. Canada — province-of-consumption governs tax rate

• Royal Bank v. Canada — incomplete invoices invalidate ITCs

• CRA policy: software implementation is taxable; software resale may require different classification

Learning insight: IT consulting = 100% taxable unless supplied to a qualifying non-resident (rare and documentation-heavy).

Why CRA Audits IT Consultants & Tech Support Firms

CRA flags tech consulting firms when it detects:

Revenue Risks

• wrong GST/HST rate for out-of-province clients (ON/NB/NS/NL)
• services to foreign clients zero-rated without proof
• bundled deliverables not separated (consulting + software license + training)
• prep/analysis work for non-residents incorrectly zero-rated
• cloud migration taxed incorrectly
• MSP monthly retainers miscoded
• travel & onsite service fees not taxed
• progress billing mistakes

Subcontractor Risks

• subcontracted developers without GST numbers
• contractors issuing invalid invoices
• employee vs contractor misclassification
• large subcontractor expenses without documentation

ITC Risks

• missing invoices for:
– cloud services
– software subscriptions
– servers, laptops, monitors
– networking equipment
– cybersecurity tools
• imported SaaS missing s.218 self-assessment
• ITCs claimed on personal-use devices
• partial-use assets misallocated

Operational Risks

• inconsistent billing across projects
• project documentation not matching revenue
• retainer payments not reconciled
• cross-border payments misclassified
• time entries inconsistent with invoices

High-risk IT consulting profiles:

• independent consultants

• MSP/IT support companies

• software implementers

• cybersecurity firms

• IT staffing contractors

• cloud architecture teams

• ERP/CRM implementation specialists

Learning insight: CRA assumes rate errors + invalid ITCs + subcontractor non-compliance in tech consulting unless disproven.

CRA IT Consulting Audit Process

1. CRA requests:
   – client list with provinces/countries
   – contracts, SOWs, MSAs
   – invoices & timesheets
   – subcontractor invoices
   – SaaS/software invoices (Azure, AWS, Google Cloud, Atlassian, Microsoft 365, Adobe)
   – ITC spreadsheets
   – bank & Stripe/PayPal statements
   – project documentation
   – imported software records (self-assessment)

2. CRA tests:
   • correct GST/HST rate by client province
   • zero-rating proof for non-residents
   • ITC documentation validity
   • imported software → self-assessment
   • subcontractor GST compliance
   • consistency between timesheets & invoices
   • personal vs business devices
   • bundled deliverable classification

3. CRA issues Proposed Audit Adjustment.

4. Mackisen CPA prepares complete CRA-standard audit defense.

Learning insight: CRA examines client location, service type, ITCs, subcontractor validity, and imported software.
