# ITR deadline August 31: late filing penalties and extended dates 2026-08-20T03:36:55+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet (2 source reports) The August 31, 2026 deadline for filing income tax returns applies to taxpayers with business or professional income using ITR-3, ITR-4, ITR-5, or ITR-7 who are not required to get accounts audited. Missing this date allows filing a belated return until December 31, but incurs penalties: up to Rs 5,000 for income above Rs 5 lakh, and up to Rs 1,000 for income up to Rs 5 lakh. Interest at 1% per month on unpaid tax also applies under Section 234A. Certain taxpayers get more time. Those under presumptive taxation liable for audit have an October 31 deadline. Transfer pricing cases have until November 30. Audit cases under section 44AB must file by October 31. Taxpayers can also file a revised return under Section 139(5) by December 31, 2026, or by March 31, 2027 with a late fee. Livemint reports that taxpayers should check forms like ITR-3 (for business income not eligible for presumptive taxation) and ITR-4 (for presumptive taxation income up to Rs 50 lakh). Supporting documents include Form 16A (TDS on non-salary income), Form 26AS and Annual Information Statement for transaction details, and audit reports Form 3CB-CD for audit cases. Forms 15G/15H can be used to claim nil or lower TDS on interest income. ## Indian Opinion Analysis Both Livemint articles are neutral-report, providing a factual checklist of deadlines, penalties, and forms with no government slant or criticism. The first article emphasises consequences of missing the deadline and options like belated and revised returns. The second focuses on correct ITR forms and supporting documents. Together they offer a complete compliance guide. A careful reader should note that penalties are capped but interest accrues monthly, making timely filing financially important. The key date to watch is December 31, 2026, the last day to file a belated or revised return without additional barriers. ## Coverage Coverage: 2 sources, 2 neutral - livemint.com (neutral report) Straight compliance guide on deadlines, penalties, and extensions - livemint.com (2) (neutral report) Factual checklist of ITR forms and supporting documents for taxpayers This story was synthesised by AI from the 2 sources linked above.
