Tax Audit Due on 21 October: Your Final Checklist Before Filing

Updated: 19 October 2026

Your income-tax return may be due in November, while an audit-report deadline arrives this Wednesday. If you are preparing an AY 2026–27 filing, check the two obligations separately before assuming that your paperwork can wait.

The CBDT announcement extends the applicable audit-report date to 21 October 2026 and the corresponding ITR date to 21 November 2026. It covers the persons specified at Serial No. 2 of the table below Explanation 2 to section 139(1). Read the official announcement. The e-Filing portal also identifies Circular No. 07/2026, dated 28 September 2026, as the extension authority.

Scope matters: this is not a fresh filing window for every taxpayer. Ask your CA to confirm the provision, form and due date applicable to your case. Do not assume that a transfer-pricing case or an ordinary non-audit return follows this timetable. This article records the position checked on 19 October; review official updates before acting on a later date.

1. Confirm the year and the report

Put the assessment year and form name at the top of your working checklist. Avoid identifying a document only as “this year's audit”: your accountant may have several reporting periods open at once.

For a section 44AB tax audit, the department distinguishes Form 3CA, where the accounts require audit under another law, from Form 3CB in other cases; the prescribed particulars accompany the report in Form 3CD. Source: Income Tax Department's form guidance. Let the CA determine which form applies rather than choosing by a familiar filename.

2. Give your CA one organised set of records

Collect the trial balance, financial statements, ledgers, bank statements and supporting schedules already requested by the auditor. A folder with clear names and one agreed version is easier to review than several message threads containing different totals.

• Sales and receipts: explain material differences between the books, bank credits and GST records, where applicable. A bank receipt is not automatically a sale; identify transfers, loans or other items with evidence.
• Expenses and balances: provide invoices, outstanding-payable schedules and explanations for unusual entries. Highlight unresolved items instead of quietly inserting an estimate.
• Tax records: share relevant TDS statements, challans, Form 26AS and AIS information. Ask the CA to reconcile differences; do not change correct books merely to make every report display the same figure.
• Assets and financing: keep purchase documents, loan statements and the schedules requested for depreciation or interest review together.

This is an organisational checklist, not a complete list of audit procedures. The records needed depend on the business and the issues identified during the audit.

3. Close questions with an owner and a time

Make a short list of open queries. For each item, record the person who will supply the evidence, the expected time and whether the auditor has reviewed the response. A document sent is not necessarily a query resolved.

For example, a business owner may have forwarded a bank statement while a loan credit still lacks supporting details. Calling the file “complete” at that stage hides the remaining work. Ask the CA which unanswered questions prevent finalisation and deal with those first.

4. Check access before the report is ready

The official Form 3CA-3CD manual describes assigning the form to a registered CA through the e-Filing portal. It also specifies a Digital Signature Certificate for verification in that workflow. Check that the correct assignment and signing arrangements are ready before the planned submission. Source: departmental user manual.

Agree who will be available to review and complete the taxpayer's part. If an authorised signatory is travelling, resolve access and availability early rather than discovering the problem after the upload.

5. Complete taxpayer acceptance and keep proof

The department's filing instructions explain that the CA's upload is followed by the taxpayer's approval. Check Pending Actions > Worklist, review the report awaiting acceptance and complete the required verification. Save the acknowledgement after successful submission. Source: tax-audit filing FAQs.

If the report contains something you do not understand, ask the auditor before accepting it. If the portal shows an error, capture the message and time, raise the issue promptly and check the final status again after it is resolved. An attempted upload or an email saying “sent” is not the acknowledgement you need for your records.

6. Schedule the return work separately

Once the report is complete, retain the final version and list the remaining ITR tasks with your adviser. Reconcile the return to the agreed accounts and report, review the tax computation and set an internal completion date that leaves room for corrections.
