What Is an Interim Audit?

An interim audit is an audit conducted before the fiscal year-end of a client, providing the client with earlier access to audited financial statements and giving auditors more time during peak season. This type of audit helps compress the timeline needed to complete the final audit and has many benefits to the client and the auditor.

The client is able to receive their financial statements sooner, which can be especially useful for publicly held companies that only require a review at quarterly intervals. For the auditor, the time saved by conducting the interim audit can be used to engage with other clients during peak season.

Interim audits can also refer to a full audit conducted for an interim period such as a quarter or half-year. Ultimately, interim audits are beneficial to both the client and the auditor, and help to streamline the process of financial statement preparation.

Objective of Interim Audit

The main objective of an early-period assessment is to identify any misstatements or deficiencies. Interim audits are designed to reduce the amount of audit testing at the final period, allowing companies to issue annual reports to stakeholders faster. Additionally, the early-period assessment provides the audit team enough time to perform a high-quality audit. The opinion issued from an interim audit is the same as the opinion of the final year-end audit.

Generally, testing is done in two phases, with 6 months being assessed against 6 months or 9 months being assessed against 3 months.

The key advantages of interim audits are:

  • Reduced audit testing at the final period
  • Faster report issuing to stakeholders
  • Time for high-quality audits
  • Same level of opinion as final year-end audits
  • Testing in two phases: 6 months vs. 6 months and 9 months vs. 3 months

Testing Approach for Interim Audit

Assessing financial information during an early-period evaluation requires the selection of an appropriate testing approach. When deciding on the testing approach for an interim audit, the issuance date of the annual report should be taken into consideration. It is also important to determine if support from the controllers and accountants is needed. Additionally, the challenges encountered during the prior year’s audit should be discussed and taken into account. Testing performed during the interim audit will not be repeated during the final phase.

The auditor should focus on the areas that are most likely to present material misstatements. These areas will depend on the type of organization, industry, and prior year’s audit results. The auditor should also consider any changes in the organization that could potentially affect the financial statements. Examples include changes in management, new products or services, or new geographic locations.

The auditor must also define the scope and objectives of the audit, and determine the most effective testing approach. This includes selecting the type of audit tests to be used, the timing of the tests, and the level of detail of the tests. Additionally, the auditor should consider the cost of the audit, the need for specialized skills, and the resources available.

Overall, the auditor must select a testing approach that is effective in the time frame available, and ensures the accuracy of the financial statements. The auditor must also take into account the potential risks and challenges that might arise during the interim audit.


Conducting an interim audit can offer a range of benefits, from increased efficiency and accuracy in employee work to a lowered risk of fraud. It helps increase the effectiveness of management in accounting and finance, and is less expensive than other audits. It also aids in the finalizing of accounts, allowing companies to easily borrow funds from financial institutions.

The following are some of the key benefits of conducting an interim audit:

  • Increases efficiency and correctness in employees’ work
  • Less expensive than other audits and aids in finalizing accounts
  • Helps increase effectiveness of management in accounting and finance
  • Allows company to easily borrow funds from financial institutions
  • Lowers risk of fraud as books of accounts are thoroughly analyzed


An interim audit may be limited in its scope, resulting in an incomplete understanding of the company’s financial position. This is because an interim audit only covers the financial aspect of the organization, leaving out other aspects such as operational performance. Furthermore, the process of conducting an interim audit may add to the burden and mental pressure on staff, as they are required to gather additional information and documents. This can lead to risk of data manipulation, resulting in inaccurate determination of profits and decrease in company funds.

Limitations Benefits
Limited scope Faster turnaround time
Increased burden on staff Enhanced internal control
Risk of data manipulation Increased transparency
Inaccurate determination of profits Increased confidence in financial statements
Decrease in company funds Improved financial reporting


Interim audits are an important part of the overall audit process. These audits are conducted between the annual audit and are typically designed to assess the financial position of the organization in a timely manner.

An interim audit allows auditors to identify any potential issues that should be addressed before the financial statements are finalized. The testing approach used for an interim audit is typically less extensive than for an annual audit, but it provides a useful measure of the organization’s financial health.

The benefits of performing an interim audit are that it allows for timely detection of any discrepancies in the financial statements, as well as timely corrective action if necessary. However, it should be noted that interim audits are not as comprehensive as annual audits, and they may not necessarily detect all potential issues
