Income Tax Return (ITR): The last date for filing unaudited ITRs for FY 2024–25 (AY 2025–26) was September 16, 2025.
The Income Tax Department had extended the deadline twice — originally set for July 31, it was first pushed to September 15 due to updates in the ITR forms.
Later, after thousands of taxpayers reported technical issues on the income tax portal on the night of September 15, the deadline was extended by one more day.
If you filed your ITR on time but later noticed an error or missed information, don’t worry — you can still fix it.
What Mistakes Can Be Corrected?
Many taxpayers make small mistakes such as:
Entering incorrect personal details
Missing out on a source of income
Forgetting to claim a deduction
All these can be corrected by filing a Revised ITR under Section 139(5) of the Income Tax Act, 1961. Taxpayers can revise their return until December 31, 2025.
How to File a Revised ITR
Log in to the official Income Tax e-filing portal.
Go to the ‘e-File’ section and click on ‘Income Tax Return’.
Choose ‘File Income Tax Return’ and select the relevant assessment year.
Under the filing type, choose ‘Revised Return (Section 139(5))’.
Correct the errors and enter the acknowledgement number of the original ITR.
Submit and e-verify your revised return.
Important Points About Revised Returns
If the revised return shows additional tax liability, you’ll need to pay interest from the original due date until you file the revised return.
You can file a revised ITR until December 31, 2025, or before the assessment is completed — whichever is earlier.
You can even file a revised return after receiving your refund if you find an error later.
What If You Haven’t Filed Yet?
If you haven’t filed your FY25 ITR, you still have time. You can file a belated return until December 31, 2025. However, a late fee will apply:
₹5,000 penalty if your annual income exceeds ₹5 lakh.
₹1,000 penalty if your income is below ₹5 lakh.
You’ll also need to pay 1% interest per month on the unpaid tax amount. As per Section 234F, the late filing fee is ₹5,000 (or ₹1,000 for incomes below ₹5 lakh).
Limitations of a Belated Return
You cannot switch your tax regime (old to new or vice versa) while filing a belated return.
You lose the ability to carry forward losses or claim some deductions.
A belated return can still be revised — but only up to December 31, 2025.
Missed the Belated Return Too?
If you also miss the December 31 deadline, you can file an Updated Return (ITR-U) under Section 139(8A).
However, note that:
You cannot claim new deductions or reduce your tax liability in ITR-U.
It involves additional penalties and must be filed within four years of the end of the relevant assessment year.
ITR-U Penalty Structure:
Filed within 12 months → 25% additional tax on total tax + interest
12–24 months → 50% additional tax
24–36 months → 60% additional tax
36–48 months → 70% additional tax
Key Things to Remember
Always double-check your details before filing to avoid notices or refund delays.
Unpaid taxes attract interest and penalties.
As per the Income Tax Department, non-payment of taxes can lead to imprisonment of 3 months to 2 years, and for tax dues above ₹25 lakh, up to 7 years.
Final Advice
If you haven’t filed your ITR yet, do it before December 31 to avoid penalties.
And if you’ve already filed but found errors, file a Revised Return immediately to correct them and stay compliant.
