Final Audit File — Assembly, Time Limit, and Retention
## Final Audit File: Assembly and Retention
### What is an Audit File?
An Audit File is one or more folders (physical or electronic storage) that records Audit Documentation for a specific engagement.
---
### SQC-1 Requirement on Audit Firms
Under SQC-1, every audit firm must establish policies and procedures for the timely completion of the Audit File.
---
### Time Limit for Final Audit File Assembly
> Not ordinarily more than 60 days after the date of the Audit Report.
---
### Nature of the Assembly Process
Assembly of the final audit file is an administrative process only — it does NOT involve:
Performing new audit procedures, or
Reaching new audit conclusions
---
### After Assembly: No Deletion Rule
After the audit file is assembled, no documents may be deleted or discarded before the end of the retention period.
---
### Retention Period
Basis
Period
Minimum retention
7 years
Calculated from
Date of Audit Report OR Date of Group Audit Report — whichever is later
---
### Examples of Administrative Process (What IS Allowed After Assembly)
#
Administrative Activity
A
Deleting / discarding superseded documentation (earlier versions replaced by later ones)
B
Sorting, collating, and cross-referencing working papers
C
Signing off on completed checklists
D
Documenting audit evidence already discussed with engagement team members before the date of the audit report
> Key point for (D): The discussion must have happened before the audit report date — this is just documenting what was already decided, not reaching new conclusions.
Worked example
### Example 1
Q: The audit report for ABC Ltd is dated 31st March. By what date must the final audit file be assembled?
A: Not ordinarily more than 60 days after 31st March — i.e., by 30th May. (Note: This is a maximum; the firm may set a shorter internal deadline.)
### Example 2
Q: After assembling the final audit file, the audit manager wants to delete an earlier draft of the working trial balance that was superseded by the final version. Is this permitted?
A: Yes — deleting superseded documentation is an example of a permissible administrative process. However, the final version must be retained, and NO substantive audit documents may be deleted before the 7-year retention period ends.
### Example 3
Q: ABC Ltd's audit was a component of a group audit. The group audit report is dated 15th June, while ABC Ltd's individual audit report is dated 1st April. From which date does the 7-year retention period run?
A: From 15th June (the group audit report date), since it is later than 1st April. The rule is: 7 years from the audit report date OR group audit report date, whichever is later.
### Example 4
Q: After the audit file is assembled, the auditor realises she needs to perform an additional confirmation procedure because a debtor's balance looks odd. Can this be done?
A: No. Assembly of the final audit file is purely administrative. No new audit procedures can be performed after assembly. If the auditor genuinely needs to address this, it should have been done before the audit report date.
⚠️ Common exam mistakes
Stating the time limit as '60 days after the financial year end' — incorrect. It is 60 days after the DATE OF THE AUDIT REPORT.
Confusing 'administrative process' with 'no changes at all' — minor housekeeping (sorting, cross-referencing, signing checklists) IS allowed; new audit conclusions are NOT.
Forgetting the 'whichever is later' rule for group audits — the retention clock starts from the later of the individual or group audit report date.
Stating the retention period as '5 years' — the correct period under SA 230 is a minimum of 7 years.
Bare-Act text Paras 14–16 · SA 230 — Audit Documentation · click to expand
The auditor shall assemble the audit documentation in an audit file and complete the administrative process of assembling the final audit file on a timely basis after the date of the auditor's report. After the assembly of the final audit file has been completed, the auditor shall not delete or discard audit documentation of any nature before the end of its retention period. The retention period for audit engagements ordinarily is no shorter than seven years from the date of the auditor's report, or, if later, the date of the group auditor's report.
