Independence Limits That Affect Audit Engagement Letters
Why your auditor cannot also keep your books, and how to structure bookkeeping help without impairing the audit.
By Hiroshi Tanabe
Japanese practice and international independence standards both restrict auditors from preparing the financial statements they then opine on. That line protects the credibility of the auditor’s report for lenders and shareholders.
We routinely decline requests to post month-end journals, prepare tax filings, or act as a temporary controller. Those tasks belong with your in-house team or a separate accounting firm.
What we can do is explain findings in plain language, suggest the type of evidence needed for a control gap, and point to standard disclosure wording—without drafting the books themselves.
If you need both bookkeeping support and an audit, appoint the bookkeeper first, then engage the auditor. Mixing the two under one roof creates independence conflicts that force withdrawal mid-engagement.
Read the engagement letter’s non-assurance services clause carefully. If a requested task sits outside the allowed list, ask before fieldwork starts rather than after an adjusting entry is already posted by the auditor’s team.
