Why this matters to a new or growing CA practice
ICAI released a revised 2026 Guidance Note on Tax Audit under section 44AB and describes it as a practical companion addressing real-world tax-audit issues.
A new CA should use the Guidance Note to design the engagement, evidence and review process—not simply to fill clauses after the books are final.
What to understand
- Plan clause responsibility before fieldwork.
- Link each material clause to source records and reconciliation.
- Document judgement where disclosure is not mechanical.
- Review changes in law, reporting utility and guidance before finalisation.
What to do in practice
- Maintain a clause-wise working-paper index.
- Cross-link ledgers, returns and financial statements.
- Keep management representations for relevant factual assertions.
- Run a final consistency review between audit report, 3CD and return data.
Working-paper checklist
- Create a dated working-paper note stating the objective and scope.
- Keep the primary-source document or link used for the conclusion.
- Record client/practice impact, owner and next action.
- Retain reviewer sign-off for material professional judgement.
Common mistakes to avoid
- Starting 3CD without a reconciled trial balance.
- Copying prior-year clause responses without reassessment.
- Leaving review evidence outside the audit file.

Answers before you start.
Is this article a substitute for the current ICAI or regulator material?+
No. Use it as a practice orientation and working-paper checklist. Verify the current primary source for the engagement date and facts.
What should a newly qualified CA document first?+
Document the objective, scope, primary source, key facts, professional judgement, reviewer conclusion and next action.
How should a small CA firm use this guide?+
Convert the relevant points into a repeatable checklist or standard operating procedure, then adapt it to the client and engagement.
How do I keep this topic current?+
Maintain an official-update log and record the effective date and impact whenever ICAI or the regulator issues a new announcement, circular, standard or portal change.
Rules, forms, portal processes, statutory fees, timelines and eligibility can change. Confirm the current requirement for your specific case before relying on a filing or compliance step. LEGAL CENTRE is a private service-assistance platform and is not a government authority.
