FY 2025-26 Tax Audit: 30 September Deadline Remains Unchanged — What CAs Should Do
Tax Audit Deadline 30 September 2026: No Extension Yet — What CAs Should Do Now
With the 30 September 2026 tax audit deadline approaching, Chartered Accountants across India are closely watching for one key development: will the government extend the deadline or will 30 September remain the final date?
As of 21 September 2026, there has been no official CBDT notification announcing an extension.
Current Tax Audit Due Date — No Extension Announced
For FY 2025-26 / AY 2026-27, the current compliance position is:
| Compliance | Due Date |
|---|---|
| Tax Audit Report — Form 3CA/3CB-3CD under Section 44AB | 30 September 2026 |
| ITR filing for taxpayers subject to audit | 31 October 2026 |
| Transfer Pricing cases — Form 3CEB under Section 92E | Audit: 31 October 2026 / ITR: 30 November 2026 |
At present, no notification has been issued changing these dates.
For AY 2026-27, the Income-tax Act, 1961 continues to apply. The new Income-tax Act, 2025 applies prospectively from FY 2026-27. Therefore, the applicable tax-audit provisions, including Section 44AB and the existing Section 271B penalty framework, continue to be relevant for FY 2025-26.
Who Is Required to Get a Tax Audit?
The major tax-audit thresholds can be summarized as follows:
| Category | Basic Limit | Enhanced Limit* |
|---|---|---|
| Business under Section 44AB | ₹1 crore | ₹10 crore |
| Profession under Section 44AB | ₹50 lakh | — |
| Business under Section 44AD where presumptive provisions are not followed | ₹2 crore | ₹3 crore |
| Profession under Section 44ADA where presumptive provisions are not followed | ₹50 lakh | ₹75 lakh |
*Enhanced limits are subject to the prescribed conditions relating to cash receipts and payments, including the 5% threshold.
These limits should always be checked against the specific facts and applicable provisions.
Why Is There a Demand for More Time?
Several practical difficulties have contributed to requests from professional bodies for an extension.
1. A Tight Compliance Calendar
For taxpayers who are not covered by tax audit, the ITR deadline was 31 August 2026. The tax-audit report deadline follows on 30 September, while ITR filing for audit cases is generally due on 31 October.
This creates a particularly busy period for tax professionals during August, September and October.
2. Transition to the New Income-Tax Law
FY 2025-26 / AY 2026-27 is an important transition period.
Although the new Income-tax Act, 2025 comes into operation from FY 2026-27, AY 2026-27 remains governed by the Income-tax Act, 1961.
Accordingly, tax audits for FY 2025-26 continue to involve the existing framework, including Forms 3CA/3CB and Form 3CD.
This makes it important for professionals to ensure that the correct provisions and forms are being applied to the correct assessment year.
3. Availability of Forms and Utilities
Professional associations have also highlighted delays concerning the availability of certain return forms and utilities.
Tax audit work involves more than reviewing accounting records. Information reported during the audit often needs to be reconciled with the taxpayer’s return and related schedules.
4. Extensive Reconciliation and Reporting
Tax auditors need sufficient time for activities such as:
- Reviewing financial information
- Reconciling accounting and tax records
- Verifying supporting documents
- Preparing and reviewing Form 3CD
- Checking applicable tax positions
- Collecting confirmations and other evidence
- Completing professional review and authentication
The Chartered Accountants Association, Jalandhar, has referred to these additional requirements while seeking an extension of the deadline to 31 October 2026.
5. Client Information May Arrive Late
Another practical challenge is the timely receipt of complete information from clients.
Depending on the nature of the business, auditors may need:
- Final books of accounts
- Bank statements
- GST records
- TDS/TCS information
- Fixed-asset schedules
- Loan and interest details
- Related-party information
- Stock and inventory records
- Expense ledgers
- Confirmations and other audit evidence
Consequently, although the statutory deadline is 30 September 2026, the actual time available to complete an audit may be considerably shorter.
6. Filing the Audit Report Is Not the Final Step
Another important point is the approval process.
After the CA electronically submits the tax-audit report, the taxpayer is required to approve it through the income-tax e-filing account.
Therefore, leaving the entire process until 30 September can create additional risk if there are portal problems, approval delays or other technical issues.
Practical Approach: Work With 30 September as the Deadline
The safest approach for practitioners is to plan on the basis that 30 September 2026 remains the applicable deadline.
If the CBDT subsequently announces an extension, it can provide additional breathing room. Until then, an extension should not be treated as part of the working plan.
What Could Happen If the Deadline Is Missed?
Failure to complete a tax audit within the applicable time limit can have financial and compliance consequences.
Section 271B Penalty
The existing Section 271B framework provides for a penalty of:
0.5% of turnover or gross receipts, subject to a maximum of ₹1,50,000.
However, Section 273B provides relief where the taxpayer can establish reasonable cause for the failure.
Such relief should not be assumed automatically. Appropriate evidence and documentation of the circumstances are important.
Possible Consequences for Delayed ITR Filing
A delayed tax audit can also affect the subsequent ITR filing process.
Depending on the taxpayer’s circumstances, delayed filing may result in interest under Section 234A on unpaid tax and may have implications for the carry-forward of certain losses.
9-Day Action Plan for CAs
With limited time remaining, practitioners can consider the following workflow:
1. Prioritize the Pending Client List
Review all pending audits immediately and categorize clients according to complexity, outstanding information and the amount of work remaining.
2. Resolve Reconciliation Issues Early
Focus on major reconciliation areas such as:
- AIS
- Form 26AS
- GST data
- GSTR-2B
- GSTR-3B
- TDS/TCS records
These issues can consume significant time if left until the final days.
3. Complete Supporting Documentation in Parallel
Form 3CD annexures, management representations and supporting documents should be completed alongside the audit instead of waiting until the final review stage.
4. File Reports as They Become Ready
Where an audit is complete, consider filing the report promptly rather than accumulating completed reports for the final two days.
5. Identify High-Risk Delays
If a client is unlikely to provide the required information or complete the process on time, identify the issue immediately and maintain proper documentation regarding the circumstances.
6. Record Portal Problems
If technical difficulties occur on the e-filing portal, maintain appropriate records such as screenshots, error messages and relevant timestamps.
Such documentation may be useful when explaining the circumstances behind a delay.
Frequently Asked Questions
Has the tax audit deadline been extended to 31 October 2026?
No official extension has been announced as of 21 September 2026. The currently applicable tax-audit deadline remains 30 September 2026.
Practitioners should verify the latest CBDT notification before relying on any extension.
Is this the same extension given for AY 2025-26?
No. The extension applicable to AY 2025-26 was part of the previous assessment year’s compliance cycle.
For AY 2026-27, the currently applicable tax-audit deadline is 30 September 2026, unless the CBDT announces otherwise.
Should taxpayers wait for an extension before completing the audit?
It is prudent to continue preparing on the assumption that 30 September 2026 is the deadline.
If an official extension is subsequently announced, taxpayers and professionals can adjust their timelines accordingly.
Final Takeaway
At present, the 30 September 2026 tax-audit deadline remains unchanged.
With only a limited number of working days available, CAs should focus on completing pending audits, obtaining client information, resolving reconciliations and filing reports as soon as they are ready.
Plan for 30 September. Treat any future extension as additional time rather than something to depend upon.
