What is Substantive Testing?

Substantive testing is an audit procedure that examines the financial statements and supporting documentation to see if they contain errors. These tests are needed as evidence to support the assertion that the financial records of an entity are complete, valid, and accurate. There are many substantive tests that an auditor can use. If substantive testing turns up errors or misstatements, additional audit testing may be required. In addition, a summary of any errors found is included in a management letter that is shared with the client's audit committee.

The Purpose of Substantive Testing

Substantive testing is intended to provide the auditor with a reasonable level of assurance about the correctness and validity of a client’s financial reporting, or to spot possible material misstatements. Consequently, substantive procedures are designed to obtain audit evidence about the data produced by a client’s accounting system - specifically, in regard to its accuracy, completeness, and validity.

Types of Substantive Tests

The following list is a sampling of the available substantive tests:

  • Compare end-of-period account balances with those of prior reporting periods, to see if there are any anomalies

  • Conduct a ratio analysis of the financial statements to see if there are any anomalies that may require further investigation

  • Issue a bank confirmation to test ending cash balances

  • Contact customers to confirm that accounts receivable balances are correct

  • Observe the period-end physical inventory count

  • Confirm the validity of inventory valuation calculations

  • Confirm with experts that the fair values assigned to assets obtained through a business combination are reasonable

  • Physically match fixed assets to fixed asset records

  • Contact suppliers to confirm that accounts payable balances are correct

  • Contact lenders to confirm that loan balances are correct

  • Review board of directors minutes to verify the existence of approved dividends

As indicated by the examples, substantive testing is likely to include confirmation of account balances with third parties (such as confirming receivables), recalculating calculations made by the client (such as valuing inventory), and observing transactions being performed (such as the physical inventory count).

Substantive Tests for Internal Audits

Substantive testing may also be conducted by a company's internal audit staff. Doing so can provide assurance that internal recordation systems are performing as planned. If not, the systems can be improved to eliminate the issues, thereby providing for a cleaner audit when the external auditors conduct their tests at year-end. Internally-conducted substantive testing may occur throughout the year.

Substantive Testing FAQs

What is the difference between substantive testing and control testing?

Control testing evaluates whether internal controls are designed properly and operating effectively. Substantive testing examines transactions, balances, and disclosures to detect material misstatements directly. In short, control testing focuses on the reliability of the system, while substantive testing focuses on whether the reported financial information is actually correct.

Can substantive testing be performed at an interim date?

Yes. Substantive testing can be performed at an interim date, but the auditor must address the remaining period before year-end. This usually requires roll-forward procedures, additional substantive work, or both. Interim testing is more suitable when controls are reliable and the risk of material misstatement is not unusually high.
