Difference between current audit file and permanent audit file

The current audit file contains documents and support for the current year. It includes leads, account balance, supports, evidence, and any other documents prepared during client field or desk audits. On the other hand, permanent audit files contain documents that remain relevant for future audits as well.

For instance, a document of leasehold land can be inserted in the permanent audit file. It’s because the land is expected to remain with the business for the long term and can be relevant support for future audits.

Similarly, audit firms assess the client’s risk before acceptance to assess if they would be able to obtain sufficient and appropriate audit evidence to form their opinion on the set of financial statements. The business risk is not expected to fluctuate significantly as operations of the business remain the same. Hence, initial risk assessment can be used in future audits and becomes part of the permanent audit file.

Further, auditors place service invoices in the permanent audit file to ensure they can track their fees and things remain in control.
