Audit Documentation (Working Papers) under SA 230

Updated 10 October 2026 · Fact-checked

Audit documentation is the record of audit procedures performed, evidence obtained and conclusions reached. These records are called working papers. Under SA 230 the auditor assembles them into a final audit file on time, ordinarily within 60 days of the auditor's report, and retains them for no less than seven years from that date.

Understand Audit Documentation (Working Papers)

Audit documentation is the written record of what the auditor did, what evidence was obtained and what conclusions were drawn. It is commonly called working papers. If it is not written down, you cannot easily prove it was done.

The record serves two broad purposes. It supports the auditor's report and shows the audit was planned and performed in line with the Standards on Auditing. It also helps the team plan, supervise and review the work, and helps later audits and inspections of the file.

The auditor does not need to keep everything. SA 230 says the auditor need not include superseded drafts of working papers and financial statements, notes that reflect incomplete or preliminary thinking, previous copies of documents corrected for typographical or other errors, and duplicates of documents.

After the auditor's report is signed, the auditor assembles the final audit file. SA 230 treats this as an administrative process. It does not involve new audit procedures or new conclusions. Only administrative changes are allowed at this stage, such as deleting superseded documents, sorting, collating and cross-referencing working papers, and signing off completion checklists.

Once assembly is complete, the auditor must not delete or discard audit documentation of any nature before the end of the retention period. If the file must be changed after assembly, the reasons, and when and by whom the change was made and reviewed, must be documented.

Students often ask about the permanent audit file and the current audit file. This is a common classification of working papers in audit practice, not a requirement of the SA 230 text supplied here. The permanent file holds information of continuing use over several years, such as constitutional documents. The current file holds the work for one audit period.

Key rules to remember

Retention period: Retention ≥ 7 years from the date of the auditor's report (or, if later, the date of the group auditor's report); SA 230 para A23. ISA 230 says five years; SA 230 says seven because the Chartered Accountants Act, 1949 and its regulations prescribe seven years for working papers.
Time limit for assembling the final file: Assembly ordinarily ≤ 60 days after the date of the auditor's report; SA 230 para A21. It is an 'ordinarily' limit, so do not call it an absolute legal deadline.
Duty on timely assembly: Assemble the file on a timely basis after the report date (para 14); The assembly is administrative and must not involve new procedures or new conclusions (para A22).
No deletion after assembly: After assembly, no deletion or discarding before the retention period ends (para 15); Applies to documentation of any nature.
Changes after assembly: Document: (a) specific reasons; (b) when and by whom made and reviewed (para 16); Applies regardless of the nature of the modification or addition. Example in A24: clarifying documentation after comments from monitoring inspections.
Administrative changes allowed during assembly: Delete superseded documents; sort, collate, cross-reference; sign off checklists; document evidence already agreed before the report date; From para A22.

How to solve Audit Documentation (Working Papers) questions

Use this method for any question on audit documentation, whether it is a short note, a case study or an MCQ.

1Identify what is asked: meaning and purpose, contents, ownership, retention, or assembly and changes after the report date.
2State the basic idea first: documentation is the record of procedures performed, evidence obtained and conclusions reached.
3Give the rule exactly, with the figure where one applies: seven years retention, ordinarily 60 days for assembly.
4Link the rule to the date of the auditor's report. Both retention and assembly run from that date.
5For case questions, ask whether the change is administrative (allowed freely) or a new procedure or conclusion (not part of assembly).
6If a change is made after the file is assembled, state that reasons, timing, who made it and who reviewed it must be documented.
7Close with a one-line conclusion that answers the question directly.

Quickest way: Date-of-report test

When to use it: Use this for MCQs and short case questions on retention, assembly or changes to the file.

Mark the date of the auditor's report as day zero.
Assembly: ordinarily within 60 days of day zero.
Retention: ordinarily no shorter than seven years from day zero.
Before assembly is complete, only administrative changes are made. After assembly, nothing is deleted, and any change needs reasons, date, person and reviewer recorded.
Reject any option that quotes five or ten years for retention in an Indian audit.

Common mistakes in Audit Documentation (Working Papers)

Writing five years as the retention period.
Students remember the ISA 230 figure from international material.
Fix: Write seven years. SA 230 para A23 prescribes seven because the Chartered Accountants Act, 1949 and its regulations prescribe seven years for working papers.
Counting retention or the 60 days from the balance sheet date or the end of the audit work.
The reference date is not read carefully.
Fix: Both periods run from the date of the auditor's report. For group audits, retention runs from that date or, if later, the date of the group auditor's report.
Saying the auditor may perform new procedures while assembling the final file.
Students treat assembly as a continuation of the audit.
Fix: State that assembly is an administrative process that does not involve new audit procedures or new conclusions.
Saying every draft and note must be kept in the file.
Students assume that more documentation is always better.
Fix: Mention that superseded drafts, preliminary-thinking notes, corrected copies and duplicates need not be included.
Presenting 60 days as a fixed statutory deadline.
The word 'ordinarily' is dropped.
Fix: Write 'an appropriate time limit is ordinarily not more than 60 days after the date of the auditor's report'.
Forgetting to document reasons when the file is changed after assembly.
Students think a harmless clarification needs no record.
Fix: Para 16 applies regardless of the nature of the change. Record the reasons, when and by whom it was made and reviewed.

Worked examples

Example 1

M/s Rao & Co. signed the auditor's report on Sunrise Textiles Ltd. on 30 June 2026. State the latest date by which the final audit file should ordinarily be assembled and the earliest date up to which the documentation should be retained under SA 230.

Show the solution

The reference date for both is the date of the auditor's report: 30 June 2026.
Assembly: ordinarily not more than 60 days after that date. July has 31 days, so 31 days takes us to 31 July. The remaining 29 days fall in August, giving 29 August 2026.
Retention: ordinarily no shorter than seven years from 30 June 2026, which is 30 June 2033.
Note that if there is a group auditor's report dated later, the retention period runs from that later date.

Answer: The file should ordinarily be assembled by 29 August 2026 and retained at least until 30 June 2033.

Example 2

After the final audit file of Ganga Foods Ltd. was assembled, a reviewer found that one working paper was unclear. The engagement partner wants to add a clarifying note. Another staff member suggests deleting an old, superseded schedule from the file to keep it tidy. Advise under SA 230.

Show the solution

Assembly is complete, so para 15 applies: the auditor must not delete or discard audit documentation of any nature before the end of the retention period. The superseded schedule must stay.
Adding a clarifying note after assembly is permitted, but para 16 applies regardless of the nature of the change.
The auditor must document the specific reasons for the addition.
The auditor must also document when and by whom the note was made and reviewed.
Para A24 gives a similar example: clarifying existing documentation after comments from monitoring inspections.

Answer: The superseded schedule cannot be deleted. The clarifying note may be added, provided the reasons, the date, the person who made it and the reviewer are documented.

Exam tips

Learn the two figures with their reference date: 60 days for assembly and seven years for retention, both from the date of the auditor's report.
In MCQs, watch for the distractors five years and ten years. Seven is correct for SA 230.
In written answers, define documentation first, then list purpose, contents and rules in short numbered points to earn step marks.
For permanent and current file questions, give a short contrast table in words: continuing-use information versus work for one period. Say it is a practice classification.
Use the exact terms 'administrative process' and 'new audit procedures or conclusions' when explaining file assembly.

Audit Documentation (Working Papers): frequently asked questions

What is audit documentation under SA 230?

It is the record of the audit procedures performed, the audit evidence obtained and the conclusions reached. It is commonly called working papers. It supports the auditor's report and shows how the audit was carried out.

How long must audit working papers be retained in India?

The retention period is ordinarily no shorter than seven years from the date of the auditor's report. ISA 230 says five years, but SA 230 uses seven because the Chartered Accountants Act, 1949 and its regulations prescribe seven years.

What is the difference between a permanent audit file and a current audit file?

The permanent file holds information of continuing relevance across years, such as constitutional documents and key agreements. The current file holds the working papers for one audit period. This is a standard practice classification rather than an SA 230 requirement.

Can the auditor change the audit file after it is assembled?

Yes, if necessary, but nothing may be deleted or discarded before the retention period ends. Any modification or addition must be documented with the specific reasons, and when and by whom it was made and reviewed.
