Today, I offer you a list of forty work paper mistakes. If you’re an auditor or you perform review engagements or compilations, you’ve seen these–or if you’re like me, you’ve make some of these errors.
The list is based on work paper reviews I’ve done over the last thirty-seven years (and not on any type of formal study).
You will, I think, shake your head in agreement as you read them. Why? Because you’ve seen these too.
Not performing risk assessment procedures for all significant transaction areas (e.g., risk assessment procedures performed for billing and collections but not for payroll which was significant)
Not retaining the support for opinion wording in the file (especially for modifications)
Specific items tested are not identified (e.g., “tested 25 disbursements, comparing amounts in the check register to cleared checks” — we don’t know which particular payments were tested)
Making general statements that can’t be re-performed based on the information provided (e.g., “inquired of three employees about potential fraud” — we don’t know who was interviewed or what was asked or their responses)
