ITR Filing Timeline After August 31: Key Dates, Audit Deadlines and Missed Return Rules
The ITR filing calendar's next milestones after August 31 are September 30 for tax audit reports, October 31 for audit cases and corporate entities, and November 30 for transfer pricing cases. Belated and revised returns can be filed till December 31, with late fees, interest, and loss of regime choice for missed deadlines.

With the August 31 deadline now passed for non-audit business and professional taxpayers, India’s direct tax calendar enters its next critical compliance phase. While salaried individuals completed their filings on July 31, taxpayers facing mandatory audits, transfer pricing reporting, or those who missed their earlier windows must navigate a series of subsequent deadlines extending through the end of the financial year.
Understanding these milestones is essential to avoiding late-filing fees, interest penalties, and restrictions on tax regime choices.
Upcoming Milestones: Audit Reports and Corporate Returns
Taxpayers whose accounts require statutory auditing operate on a distinct filing calendar:
-
September 30: Tax Audit Report SubmissionBusinesses and professionals subject to mandatory audit provisions must have their tax audit reports furnished by a chartered accountant on or before September 30. This report must be uploaded prior to submitting the final income tax return.
-
October 31: ITR Due Date for Audit Cases and Corporate EntitiesThe deadline to file Income Tax Returns for companies, partnership firms, and individuals whose accounts are subject to tax audit falls on October 31. Working partners in audit-mandated firms also share this filing timeline.

What Happens If You Missed the July or August Deadline?
Taxpayers who missed their initial July 31 or August 31 due dates can still file a belated return under Section 139(4), but specific conditions and statutory costs apply:
-
Late Filing Fees (Section 234F): A late fee of ₹5,000 applies if total annual income exceeds ₹5 lakh. For taxpayers with an income of ₹5 lakh or less, the fee is capped at ₹1,000.
-
Interest on Unpaid Taxes: Under Section 234A, penal interest accrues at the rate of 1% per month (or part thereof) on any outstanding tax liability calculated from the day following the original due date until the actual date of filing.
- Loss of Regime Choice for Businesses: Non-audit business and professional taxpayers wishing to opt out of the default new tax regime were required to file Form 10-IEA within the original due date. Missing the deadline restricts eligible taxpayers from newly opting into the old tax regime for the assessment year. Income Tax Refund 2026 Delayed? Know the Reasons and What To Check.
-
Forfeiture of Loss Carry-Forward: With the exception of unabsorbed loss from house property, taxpayers cannot carry forward business or capital losses to offset future gains if the return is filed belatedly.
Deadlines for Rectifications and Belated Filings
The final window for submitting a belated return or correcting mistakes through a revised return closes on December 31.
Taxpayers discovering omissions or errors in previously submitted returns must furnish a revised return before this date. Filing a belated return before December 31 also ensures that eligible tax refunds can still be claimed, processed, and disbursed once the return has been successfully e-verified.
For taxpayers who miss the December 31 cutoff entirely, the Updated Return (ITR-U) facility remains an option for up to 48 months from the end of the relevant assessment year, provided it involves reporting additional income and paying incremental taxes.
