Managing Petty Cash And Employee Expense Claims Effectively

Petty cash may seem minor—but poor management can trigger major compliance issues. Missing receipts, undocumented reimbursements, and personal use of funds are red flags during CRA and Revenu Québec audits. Mackisen CPA Auditors Montreal helps businesses establish strict petty cash controls and transparent employee expense systems that ensure every dollar is tracked, justified, and audit-proof.

Legal and Regulatory Framework
Income Tax Act (Canada) Section 67: Permits only reasonable, documented business expenses.
CRA Policy IC78-10R5: Allows digital copies of petty cash receipts if auditable.
Taxation Act (Quebec) Section 34: Requires detailed expense logs for QST compliance.
CPA Canada Handbook Section 5050: Establishes best practices for internal control over cash handling.
PIPEDA: Protects employee financial and personal reimbursement data.

Key Court Decisions
Beaudoin v. The Queen (2020): Denied deductions for undocumented petty cash expenses.
Lincora Group v. Quebec (2019): Penalized lack of internal cash controls.
Tremblay Holdings v. The Queen (2021): Required proof of every reimbursement for audit acceptance.
Simard Beaudry Construction v. Canada (2019): Validated digital petty cash systems with CPA oversight.
Royal Bank v. Canada (2019): Recognized CPA-audited expense management as valid documentation.

Why CRA Targets / Issues / Enforces
CRA examines petty cash and expense claims closely because they’re often misused. When records are incomplete, CRA reclassifies payments as personal benefits or disallowed expenses. Mackisen CPA Auditors Montreal implements transparent control systems to maintain compliance and accuracy.

Mackisen refers to Mackisen Global Limited (“MGL”) and its global network of member firms and associated entities collectively constituting the “Mackisen organization.” MGL, alternatively known as “Mackisen Global,” operates as distinct and independent legal entities in conjunction with its member firms and related entities. These entities function autonomously, lacking the legal authority to obligate or bind each other in transactions with third parties. Each MGL member firm and its associated entity assumes exclusive legal accountability for its actions and oversights, explicitly disclaiming any responsibility or liability for other entities within the Mackisen Organization. It is of legal significance to underscore that MGL itself refrains from rendering services to clients.
