Specific Considerations
Materiality: Most companies have a large number of transactions involving payroll, often involving large total amounts. However, the balance sheet accounts (accruals) are normally insignificant, except for labour charged to inventory (in the case of manufacturing organizations) or capitalized to PPE or deferred costs.
Significant Risks: A significant risk is payroll fraud because most transactions involve cash—the occurrence assertion is high risk. For manufacturing companies with significant labour charged to inventory, the classification is often a significant risk (there is a potential for misclassification between payroll expense and inventory or among categories of inventory—this affects the valuation assertion for inventory).
Key Controls: Internal controls are normally good for payroll transactions because of strict federal and provincial tax laws and the potential impact on employee morale. Many companies use outside service organizations for Processing payroll. The auditor is responsible for assessing the internal controls of the outside service organization.
