Forms 3CA, 3CB and 3CD are the tax-audit report forms filed under Section 44AB. Here is what each is for.
The forms
- Form 3CA — audit report where accounts are already audited under another law (e.g. companies)
- Form 3CB — audit report where accounts are not audited under any other law
- Form 3CD — the detailed statement of particulars, attached to 3CA or 3CB
When they apply
When a tax audit under Section 44AB is required (turnover/receipts above the threshold), the CA files 3CA/3CB with 3CD.
Why it matters
The 3CD captures key tax particulars (payments, disallowances, TDS) that the department relies on.
