The Finance Act, 2026 has introduced a revised return filing calendar under Section 139 of the Income-tax Act for Assessment Year 2026-27. According to reports from Mint, this replaces the previous single deadline system with multiple due dates based on taxpayer categories. The July 31 deadline was applicable only to individuals, Hindu Undivided Families (HUFs) and other taxpayers who are not required to get their accounts audited and do not have business or professional income that qualifies for a later deadline. As per recent clarifications, the deadline depends entirely on which ITR form you file, not your income level - ITR-1 and ITR-2 filers get July 31, while ITR-3 and ITR-4 filers (non-audit cases) now get an extra month till August 31. The revised filing calendar aims to provide business and professional taxpayers with adequate time to comply with reporting requirements, with the correct deadline depending entirely on the nature of the taxpayer and applicable provisions of the Income-tax Act.
A key change in the filing calendar is the introduction of a separate August 31 due date for taxpayers earning income from business or profession whose accounts are not liable for tax audit. As reported by Mint, this includes eligible businesses and professionals opting for the presumptive taxation schemes under Sections 44AD, 44ADA and 44AE, provided they are not required to undergo a tax audit. The Income Tax Department has confirmed that the due date for filing ITR-4 for AY 2026-27 is August 31, 2026. Taxpayers in this category generally file ITR-3 or ITR-4 forms. According to Apurv Gupta, Co-founder & CEO of Otto Money, the Finance Act, 2026 has amended Section 139(1) to split that into two: 31 July for ITR-1 and ITR-2 filers, and 31 August for ITR-3 and ITR-4 filers who are not liable to tax audit. Taxpayers eligible for this deadline include freelancers, consultants, small business owners, intraday and F&O traders, and salaried individuals with additional freelance or consulting income. The deadline applies only to taxpayers whose business turnover does not exceed ₹1 crore or professional gross receipts do not exceed ₹50 lakh.
Taxpayers whose accounts are required to be audited under the Income-tax Act or any other applicable law have until October 31, 2026 to file their returns. According to Mint, this category includes businesses and professionals covered under the tax audit provisions. The audit report itself must be submitted by September 30, 2026, creating a compressed timeline for audit completion. This represents the standard deadline for most taxpayers requiring audited financial statements.
Taxpayers who are required to furnish a report under the transfer pricing provisions for specified domestic or international transactions have the longest filing window until November 30, 2026. As reported by Mint, this category includes taxpayers with complex international transactions requiring transfer pricing compliance. This represents the most extended deadline in the revised filing calendar.
Even if taxpayers miss their applicable due date, they can still file a belated return under Section 139(4) until December 31, 2026, or before completion of assessment, whichever is earlier. According to Mint, filing after the due date may result in late filing fees of ₹5,000 (₹1,000 if income is under ₹5 lakh) plus interest on unpaid tax under Section 234A. The Finance Act, 2026 has also extended the deadline for filing a revised return to March 31, 2027, giving taxpayers an additional three months to correct mistakes or omissions in already-filed returns. Additionally, late filing may result in loss of ability to carry forward certain losses and delays in processing refunds. Missing the applicable deadline can have several consequences, including interest on outstanding tax liabilities, late filing fees, loss of opportunity to carry forward certain losses, and delays in processing refunds. Filing after the due date may also require filing a belated return, which comes with additional compliance implications.
