Frequently asked questions

What is a decision tree in audit context?+
A decision tree is a structured Yes/No flowchart that helps an auditor work through whether a regulatory requirement applies, what action to take, or which audit treatment is correct. Each step asks a single closed-ended question, and the answer routes you to the next question or to an outcome. The format is useful when a statute or standard has multiple interlocking conditions (e.g., CARO 2020 has 6 entity-type exemptions plus a 3-condition small-private-company carve-out).
Are these decision trees a substitute for professional judgement?+
No. Each tree summarises the statutory / standard-based decision logic, but the auditor must apply professional judgement at each step — particularly when assessing materiality, arm's-length pricing, going-concern indicators, or fraud risk. Always refer the underlying statute, standard or rule for full text; cite the underlying source in the working papers.
How do I document the decision in my working papers?+
Under SA 230 (Audit Documentation), the working paper should record (a) the question being decided, (b) the basis (statute / standard / Rule), (c) the evidence relied on, (d) the conclusion reached, and (e) the partner sign-off. The decision tree on this page can be cited as a working aid but is not a substitute for the underlying source citation.
When was CARO 2020 made effective?+
CARO 2020 was notified on 25 February 2020. The original effective date was financial years commencing on or after 1 April 2020 (i.e., FY 2020-21). Due to COVID-19 the effective date was deferred to FY 2021-22 onwards by MCA notification dated 17 December 2020.
Is the Section 188 RPT special-resolution test the same for listed and unlisted entities?+
No. Unlisted companies follow Section 188 + Rule 15 thresholds. For LISTED entities, SEBI LODR Reg 23 imposes an ADDITIONAL "material RPT" test — material = 10% of consolidated turnover OR ₹1,000 crore, whichever is lower. For material RPTs, prior shareholder approval is required regardless of arm's-length status.
Which SAs are most commonly cited by NFRA in enforcement orders?+
Across the verified NFRA orders 2022-2025: SA 240 (Fraud), SA 550 (Related Parties), SA 230 (Audit Documentation), SA 200 (Professional Skepticism), SA 315 (Risk Assessment), SA 500 / 501 (Audit Evidence + Inventory) and SA 600 (Using Work of Other Auditors). The "Section 143(12) fraud reporting" decision tree above is informed by repeat findings on delayed / missed ADT-4 filings.
