Last reviewed: 25 September 2026. Form 3CD is a questionnaire pretending to be a form — and every clause maps to documents. Assemble the pack before the audit starts and the season is administrative; assemble it during and everything runs late. Applicability and due dates live in the 44AB guide; this is the pack itself.
This pack is for the FY 2025-26 audit season, which stays under the Income-tax Act, 1961, so the 1961 section numbers used below are the correct ones for this year's report.
The core books set
- Trial balance, ledgers, cash/bank books — closed, not “nearly closed”
- Bank statements for every account, reconciled
- Sales/purchase registers tying to GST returns (the first cross-check every auditor runs)
- Stock records/valuation working as your method requires
- Fixed-asset register with additions/deletions and depreciation working
Clause-driven documents (the ones assembled late every year)
| 3CD clause | Area | Documents to keep ready |
|---|---|---|
| Clause 21 | Inadmissible amounts, including cash payments (40A(3)) | Expense analysis; exception log with reasons and evidence for any threshold-crossing cash payment |
| Clause 22 | MSME payments: 43B(h) and interest under section 23 of the MSMED Act | Udyam status of each supplier, agreed credit terms, invoice-wise ageing and payment dates |
| Clause 23 | Related parties (40A(2)(b)) | Relative/entity list, transactions summary, pricing basis notes |
| Clause 26 | 43B statutory dues | Payment proofs (before the return due date) for GST, PF, ESI, bonus, leave encashment and similar dues |
| Clause 31 | Loans and deposits (269SS, 269ST, 269T) | Loan agreements/confirmations, mode-of-transaction proof, squared-up accounts list |
| Clause 34 | TDS/TCS compliance | Deduction registers, challans, returns, defaults-and-cures summary |
| Clause 44 | Break-up of expenditure by GST registration status of the vendor | Vendor master with GSTINs and composition status; expense ledger export |
| Form 3CEB (section 92E) | International transactions of subsidiaries and branches of foreign companies | Intercompany agreements, benchmarking study, invoice and payment trail |
| — | GST cross-map | Turnover reconciliation books ↔ GSTR-1/3B ↔ e-invoice data |
| — | Presumptive/method questions | Prior-year positions, method notes, deviation explanations |
For an Indian subsidiary of a foreign group, the 3CEB file usually takes longer than the 3CD pack; our foreign subsidiary accounting and FEMA support covers the intercompany side.
Worked example: the turnover bridge
A Thane distributor's books show revenue of ₹4,82,00,000 for FY 2025-26, but its GSTR-1 returns for the same months total ₹4,95,40,000. The auditor will ask for this bridge on day one:
| Item | Amount (₹) |
|---|---|
| Taxable value in GSTR-1, April 2025 to March 2026 | 4,95,40,000 |
| Less: FY 2024-25 invoices reported in the April 2025 GSTR-1 | (3,10,000) |
| Add: March 2026 invoices reported in the April 2026 GSTR-1 | 2,20,000 |
| Less: credit notes booked in the accounts, not yet reported in GSTR-1 | (8,50,000) |
| Less: stock transfers to an other-state branch (taxable in GST, not revenue in the books) | (4,00,000) |
| Revenue as per books | 4,82,00,000 |
Each line needs its own support: an invoice list, the credit notes and the branch transfer register. An unexplained difference turns into a question in the report and, often, in scrutiny later.

- Last year’s audit observations answered IN WRITING before this year starts
Frequently asked questions
When should the pack be ready?
Weeks before the audit-report due date, not days. For AY 2026-27 the tax audit report is due by 30 September 2026 unless CBDT extends it, so a pack still being built in the last week of September is already late.
What happens if the audit report is late?
Section 271B of the 1961 Act allows a penalty of 0.5% of turnover or gross receipts, capped at ₹1,50,000, unless there was reasonable cause. From tax year 2026-27 the same penalty sits in section 446 of the Income-tax Act, 2025.
Our books are on Zoho/Tally — is export enough?
Exports are the start; the pack is exports PLUS the reconciliations and clause documents no software emits by itself. The system saves typing, not thinking.
What does the auditor check first?
Turnover ties: books vs GST returns vs e-invoice data — because it is fast and revealing. Walk in with that bridge done and the tone of the audit changes.
We have unsecured loans from family. What papers?
Confirmations with PAN, banking-channel proof, and terms — the loans clauses are where informal borrowings meet formal questions; paper them before the audit asks.
Is the MSME 43B(h) working really the auditee’s job?
The data (vendor classification, ageing) can only come from your records — auditors verify, they cannot invent it. Build it once and it also feeds MSME-1 where applicable.
We are the Indian subsidiary of a foreign company. What else goes in the pack?
The transfer pricing file: intercompany agreements, the benchmarking study, invoices and payment trail for every international transaction, and the data for Form 3CEB under section 92E. For AY 2026-27 Form 3CEB is due by 31 October 2026. From tax year 2026-27 the accountant's report sits in section 172 of the Income-tax Act, 2025.
Can prior-year observations just be ignored?
They repeat until cured — and repeated observations read badly in credit and scrutiny alike. The written “fixed because” note is cheap credibility.
Who signs what — us or the auditor?
Management representations and the underlying facts are yours; the audit report is the auditor’s. The pack exists so both signatures rest on evidence.
Can the CA who writes our books also be our tax auditor?
No. ICAI's Council guidelines bar a chartered accountant from accepting the tax audit of an entity whose books he, or his firm, writes. If one firm closes your books, a different, independent firm must carry out the tax audit.
Does a clean pack lower audit fees?
Auditors price time and risk — indexed packs cut both. No promises, but the incentive alignment is real.
For clients where we are not the statutory tax auditor, we close books, build the clause-wise pack and reconciliations, and support the audit through to signature.
