The ITR-U (Updated Return) is a "pardon" facility introduced by the government to allow taxpayers to voluntarily correct errors, disclose missed income, or file a return they missed entirely—even after the original and belated filing deadlines have passed.
As of February 2026, there have been significant updates to this form following recent budgets.
1. The Big Update: 4-Year Window
Unlike the previous 24-month rule, the government has extended the window. You can now file an ITR-U for up to 4 years (48 months) from the end of the relevant Assessment Year (AY).
Current active windows (as of Feb 2026):
| Assessment Year (AY) | Financial Year (FY) | Deadline to file ITR-U |
| :--- | :--- | :--- |
| AY 2021-22 | FY 2020-21 | March 31, 2026 |
| AY 2022-23 | FY 2021-22 | March 31, 2027 |
| AY 2023-24 | FY 2022-23 | March 31, 2028 |
| AY 2024-25 | FY 2023-24 | March 31, 2029 |
2. The "Cost" of Correction (Additional Tax)
ITR-U is not free. To "buy" peace of mind and avoid legal notices, you must pay an additional tax (penalty) on the aggregate of your tax and interest:
Within 12 months from the end of the AY: 25% additional tax.
Within 24 months: 50% additional tax.
Within 36 months: 60% additional tax.
Within 48 months: 70% additional tax.
3. Who Should File ITR-U?
You can file this form if you:
Missed the deadline: Forgot to file your original, belated, or revised return.
Underreported Income: Realized you missed bank interest, capital gains, or freelance income.
Wrong Head of Income: Reported business income as "Other Sources" (or vice versa).
Reduced Loss: Want to decrease the amount of carry-forward loss you previously claimed (to be safer/more accurate).
4. Who CANNOT File ITR-U?
The IT Department has strict "No-Go" zones for Updated Returns:
For a Refund: You cannot file ITR-U to claim a new refund or increase an existing one.
To Reduce Tax: You cannot use it to decrease your tax liability.
For a Loss: You cannot file a "Nil" or "Loss" return using ITR-U (unless you are reducing a previously claimed loss).
Under Scrutiny: If the department has already initiated a search, survey, or assessment against you.
5. Important Rules to Remember
One-Time Chance: You can file only one ITR-U per Assessment Year. If you make a mistake in your ITR-U, you cannot revise it.
Tax First, File Later: You must pay all taxes, interest, and the penalty before you hit the submit button. The challan details must be entered in the form.
No Regime Swap: You cannot change your tax regime (Old vs. New) using ITR-U; you must stick with whatever was chosen (or defaulted) in the original window.
Quick Tip: If you've received an automated "nudge" or SMS from the Compliance Portal about a mismatch in your AIS (Annual Information Statement), ITR-U is your best tool to fix it before it turns into a formal tax notice.
DOCUMENTATION -
- PAN
- Aadhaar Number
- Assessment Year
- Whether return previously filed for this assessment year? (Yes/No)
- If yes, Whether filed u/s 139(1) Others
- If applicable, enter form filed, Acknowledgement no. or Receipt No. and Date of filing the original return (DD/MM/YYYY)
- Are you eligible to file an updated return? i.e., a person is not falling in such circumstances wherein an updated return can’t be filed.
- Selecting the ITR form for filing an updated return
- Late filing is always associated with penalties. One would need to pay an additional 25% percent of the tax and interest due on the income missed to be reported if the return is filed within one year from the end of the relevant assessment year. The penalty gets enhanced to 50 percent of additional tax and interest due if the return is filed after one year and within two years of the relevant assessment year.
