Updated Return Under the Income-tax Act, 2025 — Filing Guide, 48-Month Window & Additional Tax

Last Updated: 15 April 2026  |  Applicable From: Tax Year 2026-27 (1 April 2026 onwards)  |  Reference: Income-tax Act, 2025 (30 of 2025), as amended by Finance Act, 2026; Sec 139(8A) equivalent

The updated return is one of the most taxpayer-friendly features in modern Indian direct tax law. Introduced in the Finance Act, 2022 and significantly expanded under the Finance Act, 2025 and carried forward into the Income-tax Act, 2025, it lets honest taxpayers — and even dishonest ones who later come to regret their choices — come clean about undisclosed income by paying tax, interest, and a graduated additional tax, without going through an adversarial assessment. For practising CAs, this is the tool of choice for clients who realise a mistake after the belated/revised return deadline has passed. This guide covers every aspect of the updated return under the 2025 Act for tax year 2026-27.

1. Concept and purpose of updated returns

The updated return was introduced to offer taxpayers a non-adversarial route to regularise past tax defaults. Before 2022, a taxpayer who missed reporting some income had two broad options after the belated/revised return deadline: (a) do nothing and hope the Department never detected the omission, or (b) wait for a scrutiny notice, which would involve penalty of 50% to 200% of tax, interest, and potential prosecution. Neither option was attractive.

The updated return created a third way — voluntary disclosure for a price. Pay the tax, pay the interest as if the income had been timely disclosed, and pay an additional tax as a penalty-substitute for the late disclosure. In exchange, the Department cannot then initiate penalty proceedings under Chapter XXI of the 2025 Act for the same income. The updated return has proven immensely popular — lakhs of ITR-Us have been filed in the first few years of the regime, and it is now a standard tool in every CA’s practice.

2. 48-month time limit under the 2025 Act

The most important enhancement under the Income-tax Act, 2025 (introduced via Finance Act, 2025 amendments preserved in the 2025 Act) is the extension of the updated return window from 24 months to 48 months from the end of the relevant tax year. This gives taxpayers four full years to come forward voluntarily.

3. Graduated additional tax rates

The additional tax is now a four-band graduated structure:

The 60% and 70% bands are new under the Income-tax Act, 2025. They reflect the policy choice that later disclosure should cost more — a taxpayer waiting three or four years to come clean effectively pays more than someone who comes forward within 12 months.

4. Who can file an updated return

Any taxpayer can file an updated return, subject to the ineligibility rules in Section 5 below. The following cases are all eligible:

• A taxpayer who originally filed a return and now wants to disclose additional income
• A taxpayer who originally filed a belated or revised return and wants to update again
• A taxpayer who did not file any return at all for a past tax year and now wants to file
• An individual, HUF, firm, LLP, company, AOP, BOI, trust, or any other person
• Both residents and non-residents with Indian-sourced income

Only one updated return per tax year is allowed. If you file an updated return today for tax year 2024-25, you cannot file a second updated return for the same year later. Choose wisely — get the numbers right on the first updated return.

5. When an updated return cannot be filed

An updated return is NOT permitted in any of the following situations:

• The updated return results in a lower tax liability than the original return. Updated returns are one-way — more tax only.
• The updated return claims or enhances a refund. You cannot use ITR-U to claim money back.
• The updated return converts a loss return into one with reduced loss, nil loss, or a smaller loss. You cannot use ITR-U to increase your carry-forward loss either.
• Assessment, reassessment, revision, or rectification proceedings are pending for the tax year under the Chapter XVI procedures of the 2025 Act.
• A search under the Sec 132 equivalent has been initiated, or a survey under the Sec 133A equivalent has been conducted, against the taxpayer.
• A requisition under the Sec 132A equivalent has been made for the taxpayer’s books, assets, or documents.
• A show-cause notice has been issued for the relevant tax year, whether for assessment, penalty, or prosecution.
• Information is already available with the Department regarding undisclosed foreign income or asset for the taxpayer.
• Prosecution proceedings have already commenced against the taxpayer for the relevant tax year.

6. Computation of tax, interest and additional tax

The total payment on an updated return is built up in three layers:

1. Tax: The tax that would have been payable on the updated total income at the applicable rate, reduced by any tax already paid (TDS, advance tax, self-assessment tax, original return tax).
2. Interest: Interest under the Sec 234A/B/C equivalents of the 2025 Act computed as if the income had been originally disclosed — i.e. as if the updated figures were the original figures, interest flows from the original due dates.
3. Additional tax: 25% / 50% / 60% / 70% of (tax + interest) computed above, based on when the updated return is filed.

8. Step-by-step e-filing procedure

1. Log in to incometax.gov.in using PAN and password
2. Navigate to e-File → Income Tax Return → File Income Tax Return
3. Select the relevant assessment year / tax year. The portal may still use AY terminology for old years
4. Under “Filing type”, select “Updated Return under Sec 139(8A)” (or its equivalent label under the 2025 Act)
5. Select the applicable ITR form (ITR-1 to ITR-7). ITR-U will be generated along with it
6. Enter the updated figures — income, deductions, tax liability
7. Compute tax payable, interest, additional tax using the updated return schedule
8. Pay the total amount via Challan ITNS 280, selecting “Self-Assessment Tax” or the specific updated return code. Note the CIN (Challan Identification Number)
9. Enter the CIN in the return and reconcile
10. E-verify using Aadhaar OTP, DSC, EVC, or bank account EVC. The updated return is deemed filed upon successful e-verification
11. Save the acknowledgement (ITR-U Acknowledgement) for records

9. Common reasons to file an updated return

• Missed reporting of interest or dividend income reflected in AIS but not in the original return
• Missed reporting of capital gains — most commonly from property sale or listed shares where the broker statement was not matched with the return
• Foreign income or foreign asset not disclosed in the original return (subject to Black Money Act implications)
• Incorrect regime selection that the taxpayer wants to amend — but note, you cannot switch from old to new to reduce tax
• Disclosure of cryptocurrency or VDA transactions that were omitted (see our VDA tax guide)
• Corrections to TDS credit where incorrect amounts were initially claimed
• Non-filing regularisation — taxpayer who should have filed but did not, now wants to come clean

10. Updated return vs assessment penalty

A common question is whether filing an updated return is cheaper than waiting for a scrutiny notice. In almost every case, yes:

The updated return is almost always cheaper than waiting for scrutiny — especially for misreporting cases where the Chapter XXI penalty is 200% of tax, compared to the maximum 70% additional tax under ITR-U. For routine under-reporting, the math still favours voluntary disclosure in almost every case.
