The request follows an August filing period that professionals say left a narrow window for audit work. Auditors still have to verify books, GST and TDS data, AIS or TIS entries, bank records, stock schedules and other documents before signing a report. For businesses, a rushed audit can lead to mismatches or a missed filing. Errors can also carry into the October ITR process and create later corrections or tax queries.

How Will The September 30 Deadline Affect Businesses And Professionals?

The immediate issue is whether a business can finish its records under the date that still applies. The September 30, 2026 date is still showing on the Income Tax Department portal for AY 2026-27 tax audits. For this filing, Forms 3CA, 3CB and 3CD continue under the Income-tax Act, 1961. Smaller businesses may find the deadline harder to meet, especially when their accounts are handled by outside CAs or tax firms. An accounts book may look finished but still contain a GST turnover difference, a TDS entry missing from the books or a bank transaction that needs an explanation. Any of these can delay finalisation when records arrive late.

The current compliance position is below.

The table shows why businesses should not plan around the requested date. October 31 is currently the ordinary ITR date for audit cases, while September 30 remains the earlier audit-report cut-off. If CBDT changes the schedule, taxpayers get extra room. Until then, October 31 is only the date being sought.

From a LoansJagat editorial view, any extension is better treated as extra review time, not as permission to delay unfinished work. A firm that closes reconciliations now can use later relief to recheck disclosures. A firm that waits may still be chasing invoices, bank confirmations, and vendor balances in the final days.

Why Are Tax Professionals Asking For Another 30 Days?

AIMTPA sent representation Ref. AIMTPA/001/26-27 dated September 16, 2026 to the Union Finance Minister. It asked for the tax audit report date to move from September 30 to October 31 and the audit-case ITR date from October 31 to November 30. Its main argument was the narrow period between the August non-audit filing season and the September audit deadline.

The association said the same chartered accountants, tax practitioners and staff often handle both sets of filings, especially for MSMEs. Tax audits then require books to be checked against GST data, TDS records, AIS or TIS, stock, loans, fixed assets and statutory payments. That takes more work than uploading a form. Professionals are asking for enough time to verify those figures before they enter the final audit report.

Haryana State Tax Bar Association representatives have also sought at least 30 additional days. Similar requests have come from other professional groups. Their case is that more time can reduce last-minute mismatches and revised filings. CBDT, however, has not accepted October 31 for AY 2026-27 as of September 22.

What Do Tax Experts Say Businesses Should Do Now?

Practitioners speaking during the current filing season have pointed to a compressed work period, reconciliation delays, and reported portal problems involving logins, OTPs, and DSCs. Those technical complaints come from professionals, not from a CBDT finding. Taxpayers should therefore work to the published September 30 date and keep proof if a genuine technical failure occurs.

Businesses with unfinished audits should send their CA the latest trial balance, GST reconciliation, TDS or TCS records, AIS and Form 26AS checks, bank statements, loan schedules, stock details, fixed-asset records and statutory payment information. Waiting for the final 24 hours leaves little time to answer a query raised during review.

CBDT's Form 3CD changes also affect this filing season. Form 3CD changed under Notification No. 23/2025 issued on March 28, 2025. The new rules apply from April 1, bringing some additional transaction reporting for businesses.

There is also a penalty risk for late filing. Section 271B sets it at 0.5% of sales, turnover or gross receipts, with a ₹1.5 lakh cap. Reasonable-cause provisions can apply depending on the facts, so the maximum penalty is not automatic in every delayed case.

The better business response is fairly basic but often left too late. GST turnover should agree with the books or carry a documented explanation. TDS entries need matching. Loans and statutory payments should have supporting records. If an auditor raises a difference on September 29, the finance team may have only hours to trace it.

What Happened When The Deadline Came Under Pressure Last Year?

There is recent precedent. The Ministry of Finance, in its Press Information Bureau news release dated 25.09.2025, announced the extension of the date of audit for AY 2025-26 from 30.09.2025 to 31.10.2025 by the CBDT. Professional bodies had reported a number of difficulties in completing the audit in due time; floods and natural calamities had derailed work in parts of India, the official release said. That decision explains some of the expectation this year, but it does not create an automatic extension for 2026. Each assessment year needs its own official order. Last year's announcement came only 5 days before the original deadline, which may encourage some taxpayers to wait again. There is no assurance that the same timing or relief will repeat.

The 2025 release also said the e-filing portal was operating smoothly at that point and recorded successful tax audit report uploads. That makes attribution especially important this year. Complaints about login failures or DSC errors may be genuine practitioner experiences, but they should not be presented as an official admission that the portal is failing nationwide.

One transition point also needs attention. FY 2025-26 belongs to AY 2026-27 under the Income-tax Act, 1961 for this audit filing. The newer Form 26 under the Income Tax Act, 2025 applies to Tax Year 2026-27, and its audit report is due in 2027. Businesses filing now should continue with Forms 3CA, 3CB and 3CD.

What Are Stakeholders Asking CBDT To Change?

AIMTPA wants a 1-month gap added to the audit calendar. Its September 16 representation also asked for the revised schedule to continue in later years, reducing the need for fresh extension campaigns every September. The association argued that a more predictable gap would give practitioners time for verification rather than pushing separate filing cycles close together.

Tax bar representatives have taken a similar position. They are not asking to remove the audit requirement. Their request is for more time to complete verification and supporting documentation before reports are filed. For businesses, that means an extension would change the date, not the duty to maintain books or provide correct figures.

There is a wider taxpayer angle as well. Many MSMEs depend on external accountants, so an incomplete sales reconciliation or late bank statement can hold up the whole audit file. Larger companies usually have internal finance teams, but they may face more transactions, vendor accounts, and supporting records. The pressure looks different, yet the filing date is the same.

The practical route is to work from September 30 backwards. Pending records should move to the auditor first. Differences in turnover, TDS, and bank balances should come next. Taxpayers should then leave enough time for the CA's final review and electronic filing instead of treating the upload as the only task.

Conclusion

September 30, 2026 remains the date businesses must work towards. Professional bodies have asked for October 31 because audit work follows closely after the August filing period and requires several checks before a CA can sign the report.

Last year's CBDT extension keeps expectations alive, but precedent does not change this year's deadline. Businesses that finish books, tax matching and supporting schedules now are prepared either way. If another 30 days arrive, the time can be used for review. If no relief comes, the filing work is already in place.
