If an omitted procedure weakens the auditor’s ability to back up the opinion they already issued, perform the omitted procedure or find alternative ways to test it. Write down why you made that call and get a written statement from management.
What’s Happening
An omitted audit procedure is simply a step the auditor planned to take but never got around to.
As of 2026, auditing standards still demand that the auditor ask whether skipping that step now leaves them unable to stand behind the original opinion. The key questions: Are people still relying on those financial statements? And does what the auditor has in hand today still hold up?
Here’s How to Fix It
Stop issuing new reports until you’ve addressed the omission.
- Pause any fresh audit opinions or re-issuances while you sort out the missing step.
- Re-perform the exact test you skipped—same sample sizes, same criteria, same everything. Log the date, the population, how you picked the sample, and what you found.
- If you can’t rerun the original test, cook up a different procedure that gives you the same comfort level. For instance, if you forgot to send a confirmation letter, dig through later cash receipts or bank statements to check the same financial statement assertion.
- Compare the new evidence to what you already had. Update your working papers so everything reflects the revised set of facts.
- Recalculate your detection risk and ask yourself whether the original risk assessments still make sense. If they don’t, tweak your audit plan accordingly.
- Ask management for a written note that admits the omission and swears nothing material changed afterward.
- If your reassessment flips your conclusion, issue a revised report with an emphasis-of-matter paragraph spelling out exactly what was missed and how it changes the picture.
Still Stuck?
Bring in a fresh set of eyes.
- Ask a partner in your firm who wasn’t on the job to review your work independently.
- If the omission wrecks the opinion and no other evidence will save it, consider downgrading to a qualified, adverse, or disclaimer report.
- If lawsuits or regulators might come knocking, talk to your lawyer before you publish any revised report.
How to Keep It From Happening Again
Build a few guardrails into your process.
Add a pre-issuance checklist in your audit software that flags every procedure marked “not performed.” Set up a live dashboard that tracks completion rates for every required step in the audit program. Schedule a debrief within 30 days of wrapping up the engagement to review any missed steps and update your firm’s methodology. And rotate audit seniors every year so no one gets too cozy with the same clients.
