Tax Audit Due Date Extension 2026: Current Position for AY 2026-27

Position reviewed on 19 September 2026: for ordinary tax audit cases relating to FY 2025-26 / AY 2026-27, the due date for furnishing the tax audit report remains 30 September 2026. Taxpayers and professionals should not plan on an extension unless CBDT formally changes the date.

There is significant discussion around a possible tax audit due date extension 2026. For CA firms, however, the safer approach is to work backwards from the existing deadline and complete the financial statements and major reconciliations first.

Which law applies to AY 2026-27 tax audit?

This is an important transition-year point. The Income-tax Act, 2025 came into force from 1 April 2026, but the tax audit for FY 2025-26 / AY 2026-27 continues to be governed by the Income-tax Act, 1961.

Accordingly, the familiar tax audit forms continue for AY 2026-27:

• Form 3CA where the accounts are audited under another law;
• Form 3CB in other applicable tax audit cases; and
• Form 3CD for the prescribed statement of particulars.

Why does tax audit season feel more compressed?

The tax audit report is only the final reporting layer. Before signing it, the audit team normally needs stable books and reviewed financial statements.

Typical work includes:

• book-to-GST and book-to-TDS reconciliation;
• tax depreciation and fixed asset review;
• MSME and Section 43B(h) analysis;
• partner remuneration, interest and TDS checks;
• cash, loan and deposit reporting;
• year-end provisions and disallowances; and
• final Balance Sheet, P&L and Notes to Accounts.

For many non-corporate entities, FY 2025-26 is also the first year in which the ICAI new financial statement format becomes applicable under Phase I where the turnover criterion is met. That can add presentation and conversion work for clients that previously used traditional Excel financials.

What should be completed before the last week?

1. Freeze the Trial Balance and list pending audit adjustments.
2. Complete turnover reconciliation with GST returns.
3. Complete TDS/TCS reconciliation and check year-end provisions.
4. Prepare tax depreciation and fixed asset movement workings.
5. Review MSME vendors and Section 43B(h) implications.
6. Finalise capital or partners' accounts and year-end appropriations.
7. Prepare the financial statements and Notes to Accounts.
8. Keep unresolved client information in one tracked pending list.

Do not let financial statement preparation become the bottleneck

A common audit-season problem is that professional review gets delayed because the team is still rebuilding financial statements in Excel.

assureOffice Financial Builder can start from traditional Excel financials or Tally data and organise available information into a structured Balance Sheet, Statement of Profit and Loss and Notes to Accounts workflow. The professional still reviews classifications, disclosures and final figures, but repetitive preparation work can be reduced.

Extension or no extension, the work still has to be completed. Instead of spending hours rebuilding financial statements, prepare the first structured draft in minutes and preserve more time for actual tax audit review.
