ITR-U Updated Return under Section 139(8A): citizen guide 2026
If you forgot to report income or never filed for a past year, you can file an Updated Return (ITR-U) under Section 139(8A) of the Income Tax Act, 1961. After the Finance Act 2025, you now have up to 48 months (4 years) from the end of the relevant assessment year to file it. You pay your normal tax, interest, and an extra “additional tax” of 25% to 70% under Section 140B, depending on how late you file. You cannot use ITR-U to claim a refund, cut your tax, or report a loss.
Short on time? Jump to the additional-tax slabs to see what your late filing will cost.
What ITR-U is
ITR-U is a one-time correction return. It lets any taxpayer voluntarily report income they missed, fix a wrong figure, or file a return they never filed. It is filed on the e-filing portal at https://www.incometax.gov.in. It always increases your tax outgo. It can never reduce it.
Why this exists
Many people discover an old mistake long after the normal deadline has passed. A salaried person realises a fixed deposit interest was never declared. A freelancer finds a 26AS entry for a payment they forgot. Earlier, once the belated and revised return windows closed, there was no legal way to come clean.
Section 139(8A) fixed that. It gives a voluntary disclosure route so honest taxpayers can correct the record and pay the dues with an extra charge, instead of waiting for a tax notice. The Finance Act 2025 doubled the window from 24 months to 48 months, effective 1 April 2025.
The trade-off is the additional tax. The later you file, the higher the percentage you pay on top of your tax and interest.
Who can file ITR-U
Any person can file an Updated Return, whether or not they filed an original, belated, or revised return for that year. You can file it to:
- Report income you missed earlier.
- File a return for a year you skipped completely.
- Correct a wrong head of income or a wrong tax rate.
- Reduce a carried-forward loss or unabsorbed depreciation that was overstated.
Who cannot file ITR-U
You cannot file an Updated Return if it would:
- Show a loss for the year (a return of loss).
- Reduce your total tax liability filed earlier.
- Result in a refund, or increase a refund you already claimed.
You also cannot file ITR-U for an assessment year if:
- A search under Section 132 or a requisition under Section 132A has been initiated against you.
- A survey under Section 133A (other than 133A(2A)) has been conducted.
- An assessment, reassessment, recomputation, or revision is pending or completed.
- An updated return has already been filed for that year.
- A show-cause notice under Section 148A has been issued after 36 months from the end of the relevant assessment year. This bar does not apply if an order under Section 148A(3) holds it is not a fit case for a Section 148 notice.
If any of these apply, ITR-U is not available for that year.
Additional tax slabs under Section 140B
The additional tax is charged under Section 140B on the aggregate of the extra tax and the interest payable on the income you are now declaring. It is not a percentage of your income. The rate depends on when you file, measured from the end of the relevant assessment year. The slabs are bands, not cumulative:
| When you file the ITR-U | Additional tax under Section 140B |
|---|---|
| Up to 12 months | 25% of tax + interest |
| After 12 and up to 24 months | 50% of tax + interest |
| After 24 and up to 36 months | 60% of tax + interest |
| After 36 and up to 48 months | 70% of tax + interest |
The 60% and 70% bands were added by the Finance Act 2025 when it extended the window to 4 years.
Step-by-step: how to file ITR-U
1. Confirm you are eligible
Check that your case is not blocked. The return must increase your tax. If it would create a loss, a refund, or a lower tax, stop. ITR-U is not for you.
2. Log in to the e-filing portal
Go to https://www.incometax.gov.in and log in with your PAN and password. PAN must be linked to Aadhaar for e-verification to work.
3. Pick the assessment year and the right ITR form
Select the assessment year you are correcting. Choose the ITR form that matches your income (ITR-1, ITR-2, ITR-3, and so on). ITR-U is filed using the normal form plus a Part B-ATI schedule for the updated-return details.
4. State the reason for updating
Pick a reason from the dropdown, such as income not reported correctly or return previously not filed. You must give a reason; it is a mandatory field.
5. Compute and pay the tax
Calculate the tax, interest, late fee under Section 234F if due, and the Section 140B additional tax. Pay the full amount through the e-pay tax option and note the challan number. ITR-U will not be accepted without proof of payment.
6. Fill, submit, and e-verify
Enter the challan details, submit the return, and e-verify it within 30 days using Aadhaar OTP, net banking, or a digital signature. An unverified return is treated as not filed.
Documents you need
- PAN and Aadhaar, linked.
- The original or belated return for that year, if any.
- Form 26AS and the Annual Information Statement (AIS) to find the missed income.
- Bank, interest, and capital-gains statements for the year.
- The tax-payment challan for the Section 140B amount.
Common mistakes
- Filing to claim a refund. Section 139(8A) bars any ITR-U that produces or increases a refund. The portal will reject it.
- Trying to report a loss. A return of loss cannot be filed as an ITR-U. You can only reduce a previously claimed loss, not create one.
- Filing without paying first. Section 140B requires the tax, interest, and additional tax to be paid before you submit. No challan, no valid return.
- Ignoring the 36-month Section 148A bar. If a notice under Section 148A came after 36 months from the year-end, the option is gone for that year.
Real-life example
Kashvi Pathak, a graphic designer in Indore, found in May 2026 that she had never reported Rs 90,000 of freelance income for assessment year 2022-23. That AY ended on 31 March 2023, so her 48-month ITR-U window closes on 31 March 2027. Filing now falls in the “after 36 months” band, so she pays her normal tax and interest plus 70% of that sum as additional tax under Section 140B. She logs in to the portal, computes the dues, pays the challan, and files the ITR-U to close the gap before any notice arrives.
Note: dates here are illustrative. Always confirm the exact closing date for your own assessment year, which is 48 months after that year-end.
What to do in the next 30 minutes
- Open your AIS and Form 26AS on https://www.incometax.gov.in and list any income you missed.
- Identify the assessment year and count 48 months from its end to confirm the window is still open.
- Check that your correction increases tax, not a refund or loss.
- Estimate the Section 140B band that applies to you using the table above.
- If the rules feel complex, ask a question on https://righttoinformation.wiki/ask before you file.
Frequently asked questions
Can I file ITR-U to get a tax refund?
No. Section 139(8A) does not allow an Updated Return that results in a refund or increases a refund you already claimed. ITR-U can only be filed when it increases your total tax liability. If your correction would create a refund, you cannot use this route.
How many years can I go back to file ITR-U in 2026?
The Finance Act 2025 extended the window to 48 months from the end of the relevant assessment year, effective 1 April 2025. So you count 4 years back from each assessment year-end. Check the exact 48-month closing date for the specific year you want to correct before you file.
What does the additional tax cost me?
It is 25% of your extra tax plus interest if you file within 12 months of the AY-end, 50% within 24 months, 60% within 36 months, and 70% within 48 months. This is over and above the normal tax, interest, and any late fee under Section 234F.
Can I file ITR-U if I got a notice under Section 148A?
You cannot file an Updated Return if a show-cause notice under Section 148A was issued after 36 months from the end of the relevant assessment year. The bar does not apply if an order under Section 148A(3) holds that it is not a fit case for issuing a notice under Section 148.
Do I have to pay before filing the ITR-U?
Yes. Section 140B requires you to pay the tax, interest, late fee if any, and the additional tax before you submit. You enter the challan details in the return. Without proof of payment, the ITR-U is not valid.
