Quick answer: The tax audit due date for AY 2026-27 (FY 2025-26) is 30 September 2026. As of 19 September 2026, the CBDT has not issued any notification extending it, so tax audit reports must still be uploaded by 30 September. The audit-case ITR is due on 31 October 2026. Transfer pricing cases have until 31 October 2026 for the audit report.
This year’s audit is also a transition year. It is the last audit under the Income-tax Act, 1961, using Forms 3CA/3CB/3CD. Form 3CD carries several revised clauses, and the new Form 26 takes over from next year. This guide covers the deadline, the current extension position, what has changed, and a checklist to use before filing.

What Is a Tax Audit Under Section 44AB?
A tax audit is an audit of a taxpayer’s books of account under Section 44AB of the Income-tax Act, 1961. A Chartered Accountant in practice carries it out and reports the findings in Form 3CA or Form 3CB, together with the detailed statement of particulars in Form 3CD.
The report is filed online on the Income Tax e-filing portal. The taxpayer must then approve it from their own e-filing account.
What is Form 3CA, Form 3CB and Form 3CD?
- Form 3CA is used when the taxpayer’s accounts are already audited under another law, such as a company audited under the Companies Act, 2013.
- Form 3CB is used when the accounts are not audited under any other law, such as a proprietorship or a partnership firm.
- Form 3CD is the statement of particulars that goes with either form. It covers turnover, disallowances, TDS, loans, deposits, GST-wise expenditure and other details.
What Is the Latest Update on the Tax Audit Due Date AY 2026-27?
The due date remains 30 September 2026. No extension has been notified as of 19 September 2026.
Have professional bodies asked for an extension?
Yes. Several associations have asked for more time:
- The Chartered Accountants Association, Jalandhar sent a representation dated 6 September 2026 to the Finance Minister. It asked for the audit date to move to 31 October 2026, with similar relief for trust audit reports and linked ITR filings.
- The Punjab Accountants Association sent a representation dated 11 September 2026 asking for the same shift, from 30 September to 31 October 2026.
- The main grievance is the compressed calendar. Non-audit business ITRs for AY 2026-27 were due on 31 August 2026, which left only about a month before the audit deadline.
Important: A representation is only a request and has no legal effect. Only an official CBDT order, circular or notification can change the due date.
Was the tax audit date extended in previous years?
Yes, but the extensions varied and came late:
| Assessment Year | Original date | Extended to | Reason cited |
|---|---|---|---|
| AY 2024-25 | 30 September 2024 | 7 October 2024 | Slow functioning of the e-filing portal |
| AY 2025-26 | 30 September 2025 | 31 October 2025 | Representations from professional bodies about disruption from floods and natural calamities |
Past extensions do not guarantee one this year. Taxpayers and auditors should work to the 30 September 2026 deadline.
Who Needs a Tax Audit for AY 2026-27?
A tax audit under Section 44AB applies to taxpayers with business or professional income who cross these thresholds in FY 2025-26:
| Category | Tax audit required if |
|---|---|
| Business (general) | Turnover exceeds ₹1 crore |
| Business with minimal cash transactions | Turnover exceeds ₹10 crore, where cash receipts and cash payments are each not more than 5% of the total |
| Profession | Gross receipts exceed ₹50 lakh |
| Presumptive taxation cases | Income declared below the presumptive rate while total income exceeds the basic exemption limit, subject to the conditions in Section 44AB |
Does presumptive taxation (Section 44AD/44ADA) avoid a tax audit?
Not always. The presumptive schemes have their own turnover limits. Under Section 44AD, the limit is ₹3 crore if cash receipts are 5% or less of total receipts, and ₹2 crore otherwise. Under Section 44ADA, it is ₹75 lakh or ₹50 lakh on the same cash test. If turnover or receipts exceed these limits, the taxpayer falls back into normal tax audit rules.
Example: A trader has FY 2025-26 turnover of ₹2.5 crore, and 8% of receipts came in cash.
- The 44AD limit is ₹2 crore because cash receipts exceed 5%, so the trader cannot use the presumptive scheme.
- The ₹10 crore Section 44AB limit also does not apply, because cash exceeds 5%.
- Turnover exceeds ₹1 crore, so a tax audit is required and the report is due by 30 September 2026.
Is tax audit applicable to salaried individuals?
No. A tax audit under Section 44AB applies only to income from business or profession. Salary, rental income or capital gains alone do not trigger it.
Which Law Applies to the Tax Audit for AY 2026-27?
The Income-tax Act, 1961 applies. The new Income-tax Act, 2025 covers the tax year starting 1 April 2026. FY 2025-26, which ended on 31 March 2026, is still governed by the old Act.
This has two practical consequences:
- Use old section numbers. Auditors should cite 1961 Act sections such as 194C and 194J in the TDS clauses for FY 2025-26, not section numbers from the 2025 Act.
- This is the last year of Form 3CD. AY 2026-27 is the final assessment year in which Forms 3CA, 3CB and 3CD are valid. Glomiq
What replaces Form 3CD from next year?
From Tax Year 2026-27, the new Form 26 under the Income-tax Act, 2025 replaces Form 3CD. It expands reporting from 44 clauses to 55 and adds new disclosures, including details of cloud storage used for books of account. Businesses should start preparing their records for the heavier reporting from next year.
What Has Changed in Form 3CD for AY 2026-27?
The CBDT amended Form 3CD through Notification No. 23/2025, which applies from 1 April 2025. The revised form puts more weight on MSME payments, loan transactions and buyback receipts, and drops some outdated clauses.
Note: The notification took effect on 1 April 2025, so parts of these changes may already have appeared in last season’s utility. Either way, all of them apply to FY 2025-26 audits.
| Clause | Change |
|---|---|
| Clause 12 | Now includes Section 44BBC in presumptive income reporting |
| Clause 19 | Rows for Sections 32AC, 32AD, 35AC and 35CCB removed |
| Clause 21 | Separate reporting of expenditure on settling proceedings for a contravention under a law notified by the Central Government |
| Clause 22 | Revised to cover interest disallowed under Section 23 of the MSMED Act, amounts payable to micro and small enterprises under Section 15, amounts paid in time, and amounts unpaid and disallowed |
| Clause 26 | Aligned with the current Section 43B framework, including Section 43B(h) for payments to micro and small enterprises |
| Clauses 28 and 29 | Omitted |
| Clause 31 | More detail required on the nature and mode of loans, deposits, specified advances and repayments, with transaction codes |
| New Clause 36B | Reporting of amounts received on share buyback under Section 2(22)(f), with the cost of acquisition |
Why do the MSME clauses (22 and 26) matter most?
Section 43B(h) allows a deduction for amounts owed to micro and small enterprises only if payment is made within the time allowed under the MSMED Act. That is 45 days where there is a written agreement and 15 days otherwise. Unpaid amounts beyond that period are disallowed for the year. Clauses 22 and 26 must report these amounts consistently, and the disallowance must flow correctly into the ITR.
Tax Audit Checklist Before Filing the Report
Use this checklist before uploading the report for AY 2026-27:
- Confirm applicability. Check turnover, cash receipt percentage and whether the presumptive scheme applies.
- Choose the correct form. Use Form 3CA where accounts are audited under another law and Form 3CB otherwise.
- Use the latest utility. Make sure the audit software and the e-filing utility reflect the revised Form 3CD clauses.
- Verify MSME status of vendors. Collect Udyam registration details, apply the 15/45-day payment test, and reconcile Clauses 22 and 26.
- Reconcile turnover with GST returns. Turnover in Form 3CD should match GSTR-1, GSTR-3B and AIS data, because mismatches can trigger automated notices.
- Check Clause 44. The GST-wise expenditure break-up in Clause 44 should reconcile with GST filings and the ITR.
- Reconcile TDS (Clause 34). Match deductions and deposits with TDS returns and Form 26AS/AIS, and report interest on delayed payments.
- Collect loan and deposit data by mode. Clause 31 needs transaction-wise information and codes for Sections 269SS and 269T reporting.
- Use old Act section references. Don’t use Income-tax Act, 2025 section numbers for FY 2025-26.
- Generate UDIN. UDIN is mandatory on tax audit reports.
- Get taxpayer approval. The report is complete only after the taxpayer accepts it on the e-filing portal.
- File before the last day. Avoid the final-week portal rush.
What Happens If the Tax Audit Report Is Filed Late?
Missing the tax audit due date can lead to a penalty under Section 271B of the Income-tax Act, 1961. The penalty is:
- 0.5% of total sales, turnover or gross receipts, or
- ₹1,50,000, whichever is lower.
Example: For turnover of ₹1.8 crore, 0.5% works out to ₹90,000, so the penalty would be ₹90,000. For turnover of ₹5 crore, 0.5% is ₹2,50,000, so the penalty is capped at ₹1,50,000.
Section 273B allows the penalty to be waived if there was a reasonable cause for the delay. Taxpayers should keep records of any genuine reason, such as portal problems or other circumstances beyond their control.
A delayed audit also delays the ITR. Missing the ITR due date brings its own late fees, interest and possible loss of some carry-forward benefits.
Common Mistakes to Avoid in the AY 2026-27 Tax Audit
- Waiting for an extension that has not been notified
- Using an outdated Form 3CD template that misses the revised clauses
- Citing Income-tax Act, 2025 section numbers in an FY 2025-26 report
- Reporting MSME dues inconsistently between Clauses 22 and 26
- Leaving GST and turnover mismatches unexplained
- Filing Form 3CB where Form 3CA applies, or the reverse
- Forgetting taxpayer acceptance after the auditor uploads the report
- Treating 31 October as the audit deadline when it is the ITR deadline for audit cases
Practical Implications for Taxpayers and Businesses
Business owners should give their auditor complete books, GST returns, vendor MSME details and loan records now.
- Taxpayers using presumptive schemes should check whether their turnover or cash receipts pushed them into audit this year.
- Professionals conducting audits should prioritise simpler cases first and get client approvals as reports are uploaded.
- Everyone should begin preparing for Form 26, which applies from Tax Year 2026-27.

This is the final year for Forms 3CA, 3CB and 3CD under the Income-tax Act, 1961, and the revised Form 3CD clauses on MSME payments, Section 43B(h), loans and deposits, and buyback receipts need careful attention.
Taxpayers should finalise books, reconcile GST and TDS data, confirm vendor MSME status, and approve their audit reports well before the deadline. Late filing can attract a penalty of up to ₹1.5 lakh under Section 271B. Any extension counts only once the CBDT officially notifies it.
