Missed The August 31 ITR Deadline, Here’s What Happens Next

The August 31 deadline stands for filing income tax returns by eligible non-audit taxpayers under assessment year 2026-27. Those still lacking submission have until today to file. While missing the deadline doesn't permanently end the window, it does carry consequences. A late penalty under Section 234F may apply—Rs 1,000 for incomes no more than Rs 5 lakh, rising to Rs 5,000 otherwise.

Interest could also accrue on the outstanding tax bill. Certain business and capital losses might become unfillable if filed late, as they must generally be reported within the original deadline under Section 139(1).

Only those in the non-audit category, including businesses or professionals with income from trade or practice, must file by the deadline. ITR-3 applies to such taxpayers who cannot use ITR-1, ITR-2, or ITR-4. ITR-4, or Sugam, is for resident individuals, HUFs and resident firms earning up to Rs 50 lakh, whose income is calculated under presumptive tax provisions Sections 44AD, 44ADA or 44AE, excluding LLPs. The deadline for the AY 2026-27 ITR-4 filing is August 31, 2026.

Taxpayers who missed the original deadline can still submit a belated return under Section 139(4), with a new deadline of December 31, 2026, or before the assessment completion, whichever comes first. The Income Tax Department urges non-audit taxpayers to file their ITR by the August 31 deadline, emphasizing the importance of completing returns on time.

Late-filing fees and interest may apply, and loss carry-forward may be affected. Taxpayers should ensure verification within the allowed time frame; an unverified return is invalid and delayed verification can extend the filing date and bring about consequences. They have 30 days to complete electronic verification or submit the ITR-V.
