Audit Assertions for Expenses

Audit of expenses can be done by testing various audit assertions of completeness, accuracy, occurrence, and cut-off. Audit procedures are relevant to gathering appropriate audit evidence in order to make a conclusion with regard to expenses.

The understatement of expenses will make look financial statements better than it is. Therefore, the auditors shall primarily look at such cases of an understatement.

In the case of auditing expenses, the most important aspect is the completeness of records in the income statement.

The lack of strong internal controls will lead to an understatement of expenses. This usually happens due to fraud committed by the internal staff.

Near the end of the reporting date, the management may try to delay incurring expenses in order to avoid getting the expenses reported.

Hence, they might do this by recording in the next accounting period and avoiding the current. This is simply understating the profits and needs to be checked by the auditors.

Here are the key audit assertions to test the assertions:

CompletenessThe expenses that have been incurred are complete records and timely recorded date of reporting
Cut-offThe expenses have been differentiated as per the accrual system and recorded in the proper accounting period.
AccuracyThe expenses are recorded accurately for the amount
OccurrenceThe expenses have been actually incurred and related to the business.
ClassificationThe expenses have been properly classified as factory, administration, and selling expenses if necessary.

The risk of being susceptible to misstatement due to the nature of the debt is the inherent risk of the debt. Control risk occurs when the internal control system of the auditee fails to prevent or detect material misstatement in the debt.

The primary inherent risk would be the understatement of expenses. This would lead to over-reporting the profits in the current accounting period. This happens when incentives are linked to profit or as a result of intense pressure from within the company.

Take, for instance, branch managers who are given a 5% incentive bonus as a percentage of profit if a certain business is achieved.

In this case, the branch manager would try to overstate profit by underreporting the profits due to the inherent structure of the incentive.

The varieties of inherent risks that may occur in the audit of expenses are as follows:

  1. The expenses have been accrued, not recorded, and not yet paid.
  2. The expenses are recorded as assets to understate the expenses and overstate the asset. Take, for instance, the installation of newly purchased machinery.
  3. The general repairs and maintenance expenses are added to the cost of fixed assets.
  4. Changing the accounting period to close books early. This has happened very rarely.
  5. Breaking down the large expenses into smaller ones to avoid checks and cut-off procedures employed by the auditors.

The varieties of control risks that may occur in the audit of expenses are as follows:

  1. Dividing duties among various staff to make purchases and receive goods and proper accounting in the system.
  2. Proper authorization on all expenses and payment
  3. Matching the purchase invoice with the amount of goods received along with the transportation invoice.

  1. Obtain all the supporting documents such as invoices, voucher slips, etc for the expense being incurred
  2. Perform further audit procedures when expenses reach the amount above the budget threshold significantly (by more than 10%)
  3. Check whether proper authorization has been done with regard to expenses.
  4. Verify that vendors exist through third-party confirmation and making surprise visits when goods are received and auditing goods received a note with the physical purchase being received.
  5. Ensure that proper classification has been made for expenses with respect to revenue expenditure and capital expenditure.
  6. Verify the related party expenses and ensure they are being reported with notes to financial statements where necessary.
