The 2026 amendments to Form 3CD have refined the clause-by-clause reporting expected in tax-audit work. This note walks through the changes that practitioners are likely to encounter most often and offers a view on what the Institute's recent guidance suggests for borderline cases.
Form 3CD — the statement-of-particulars annexed to the auditor's report under section 44AB of the Income-Tax Act, 1961 — has long been the principal document through which a tax-audit report is read. Its clause structure mirrors the substantive provisions of the Act and reflects the points on which the Department most often seeks confirmation. Each year's amendment therefore tells us where the Department's attention is concentrating; this year's amendments fall into three groups.
I. Clause 21 — expenditure-disallowance reporting
The most-discussed change is to clause 21, where the disallowable-expenditure schedule has been expanded to capture certain payments more granularly. The amendment is not, strictly, a substantive change — the disallowance provisions themselves have not changed — but the granularity of the reporting affects the practitioner's documentation requirements at the audit level.
In particular, the auditor is now expected to identify payments that fall under sections 40A(3), 40(a)(ia), and 43B by reference to specific sub-categories rather than as aggregate amounts. The Institute's guidance suggests that auditors should review the underlying ledgers with the new granularity in mind, even where the previous year's working papers were prepared on the older format.
II. Clause 31 — loans and deposits
Clause 31, which records loans and deposits accepted or repaid otherwise than by account-payee instrument, has been revised to capture a wider category of related-party transactions. The threshold remains as in the Act (sections 269SS / 269T), but the supporting schedule now requests counterparty identification details that the previous form did not.
This affects the auditor's verification approach. Where in earlier years the auditor's responsibility was substantially completed by ensuring the schedule was correctly prepared by the assessee, the revised schedule's counterparty fields require the auditor to satisfy himself or herself that the counterparty information is correctly captured.
III. Clause 34 — TDS compliance
Clause 34 has been amended to bring the late-deposit reporting in line with the latest TRACES disclosures. The form now expects the auditor to capture interest-on-late-deposit detail at a granular level, broken out by quarter, and to reconcile against the assessee's TDS returns and Form 26AS.
What this means for the audit plan
The revised reporting format reflects a wider shift toward substance-over-form disclosure in tax-audit work. The Department is using clause-level granularity to identify positions that may require further inquiry. From the auditor's standpoint, the practical implications are documentation-led: the audit plan should anticipate the new clause-level requirements and the working papers should be set up to capture the supporting evidence at the granularity the form expects.
The Institute is expected to publish a revised Guidance Note on Tax Audits within the current year. Until that is available, practitioners should rely on the form's instructions, the underlying provisions of the Act, and where genuine ambiguity remains, on a conservative interpretation that errs on the side of disclosure.
The form is a reporting instrument, not a confessional one. Where the underlying transaction has a defensible tax position, that position should be taken — with the form capturing what it asks for and the working papers documenting the basis. Disclosure does not amount to admission.
This note is published as professional information per § 3.3.8 of the Institute's Code of Ethics, 2020. It does not constitute advice to any specific reader on a specific transaction. Practitioners should refer to the underlying provisions of the Act, the Institute's Guidance Notes, and the latest CBDT circulars and notifications for the position applicable to their engagements.
