ITR-U: How to File an Updated Return Under Section 139(8A) — Deadlines, Penalties, and Who Cannot Use It

Many taxpayers discover a mistake only after the regular return deadline has passed: an income source was missed, the wrong head of income was used, or some income was underreported. ITR-U is the updated return mechanism that gives you a second chance for eligible years, but it is not a free do-over. It is governed by Section 139(8A) of the Income Tax Act, 1961, with the ITA 2025 equivalent at Section 263. The catch is simple: you can use it to add or correct income, but not to reduce income or claim a bigger refund.
If you want a quick comparison before fixing the return, use our income tax calculator to see how the tax changes before you file.
What Is ITR-U?
ITR-U is the updated return form notified by the CBDT for cases where a taxpayer needs to correct underreported income or file a return that was not filed originally. The legal basis is Section 139(8A) ITA 1961, with the equivalent provision moving to Section 263 ITA 2025.
It applies to assessment years starting from AY 2020-21 onward, because the updated return provision was introduced by the Finance Act 2022. If your case falls within the allowed window and none of the blocking conditions apply, ITR-U is the prescribed route.
The Time Limit For Filing ITR-U
The filing window is 24 months from the end of the relevant assessment year. That means the latest date depends on the AY you are correcting.
So if you are asking, "Can I file ITR after the deadline?" the answer is yes, but only through ITR-U and only if the assessment year is still within the 24-month window.
How Much Extra Tax Do You Pay?
The additional tax is governed by Section 140B ITA 1961, with the ITA 2025 equivalent at Section 267. It is not charged on gross income; it is charged on the incremental tax and interest arising from the update.
The uplift works like this:
- If the updated return is filed within 12 months from the end of the relevant AY, the additional tax is 25% of the additional tax and interest
- If the updated return is filed between 12 and 24 months from the end of the relevant AY, the additional tax is 50% of the additional tax and interest
This is why timing matters. The same correction becomes more expensive once you move into the 12 to 24 month band.
Who Cannot File ITR-U?
ITR-U is not available if any of the following apply for that assessment year:
- Assessment, reassessment, or revision has already been completed or is pending
- Search or survey proceedings are pending or have been initiated
- Prosecution has already been launched
- The dispute has already been settled under Vivad se Vishwas
ITR-U also has a hard restriction on what it can do. It cannot be used to:
- Claim a higher refund
- Reduce income already reported
- Use the updated return to lower the tax burden by switching to a smaller income figure
In plain language: ITR-U is for adding missed income or correcting underreporting, not for shrinking the tax you already disclosed.
How To File ITR-U
The process is straightforward once you know what the form expects:
- Log in to the Income Tax e-Filing portal
- Go to e-File and choose Income Tax Returns
- Select the relevant assessment year
- Choose ITR-U
- Pick the same ITR form type that applies to the original return
- Select the reason for the updated return
- Enter the corrected income details
- Compute the additional tax and interest
- Pay the amount before submitting the return
- File and verify the updated return
If you are correcting a return because the original filing was incomplete, keep the original return, the updated income documents, and the payment details together before you submit. That makes reconciliation much easier for both you and your CA.
ITA 2025 Context
The legal mapping is simple:
- Section 139(8A) ITA 1961 becomes Section 263 ITA 2025
- Section 140B ITA 1961 becomes Section 267 ITA 2025
For now, the updated return framework remains the same in substance: a time-limited correction window with an additional tax cost. The new Act changes the numbering, but the compliance logic stays familiar.
Frequently Asked Questions
Can I file ITR-U if I never filed the original return?
Yes. ITR-U can be used even if no original return was filed for that assessment year, as long as the year is still within the allowed time limit and none of the blocking conditions apply.
What is ITR-U?
ITR-U is the updated return form that lets you add missed income or correct underreporting after the original filing window has passed. It is available under Section 139(8A) ITA 1961 and the equivalent Section 263 ITA 2025.
Can I reduce my income using ITR-U?
No. ITR-U cannot be used to reduce income already reported. It is only for adding income or correcting underreporting.
Can I use ITR-U to claim an additional refund?
No. ITR-U is not available for claiming a larger refund.
What if my assessment has already been completed?
Then ITR-U is barred for that assessment year. The return cannot be used once the case has moved into completed or pending assessment, reassessment, or revision proceedings.
Bottom Line
If you missed income, found an error, or never filed for an eligible year, ITR-U is the cleanest way to fix it before the window closes. The cost rises from 25% to 50% of the additional tax and interest once you move past the first 12 months, so delay only makes the correction more expensive.
