When Accounting & Tax Professionals conduct a Test of Controls, they follow a systematic approach. First, they identify the key controls relevant to financial reporting processes. These might include segregation of duties, authorization procedures, reconciliations, or physical controls over assets.
Next, they gather evidence that shows the control is operating effectively. This evidence can come from several methods:
Inquiry: Asking your staff how they perform certain tasks or apply a control. Observation: Watching an employee perform a task, like seeing if they physically count inventory or approve an invoice. Inspection: Examining documents, like looking for signatures on invoices over a certain threshold, checking that reconciliations were prepared and reviewed, or reviewing system logs to see who accessed sensitive financial data. Reperformance: The auditor independently re-executes a control, such as recalculating a depreciation schedule or reperforming a bank reconciliation to confirm the accuracy of the company’s internal process.
The frequency and nature of these tests depend on various factors, including the control's importance and prior audit findings. If controls are found to be strong and operating consistently, the Accounting & Tax Professionals might reduce the extent of substantive testing (detailed checking of transactions) they perform. Conversely, if controls are weak, more in-depth substantive testing will be necessary to ensure the financial statements are accurate.
