Income Tax Return Due Date Deadline Extension 2025: ITR filing deadline for Financial Year 2024-25 and Assessment Year 2025-26 has been extended by one day, making September 16 the final date to file without penalty. The move came after the Income Tax Department’s e-filing portal faced technical glitches and server time-out issues.
Deadline Shifted Twice
The original deadline for taxpayers who are not subject to audit was July 31, 2025. In May, it was extended to September 15, and following widespread complaints of portal errors, the department granted a further one-day extension.
Taxpayers must keep essential documents ready before filing, such as Form 16 from employers, Form 26AS, the Annual Information Statement (AIS), PAN card, Aadhaar card (linked with PAN), investment proofs, and home loan or insurance premium receipts.
Filing and Penalty Details
To file ITR, users must log in to the income tax portal, select the assessment year, choose the correct form, fill in details, pay dues, and submit the return, followed by e-verification.
Late filing will attract 1% monthly interest under Section 234A and a late fee of Rs 5,000 for incomes above Rs 5 lakh, or Rs 1,000 for incomes below that threshold. Additionally, taxpayers lose the option to carry forward losses and certain deductions if filing after the deadline.
