Taxpayers can file ITR-U within four years from the end of the relevant assessment year. It can also be used for the preceding four assessment years (48 months). For the Financial Year 2025‑26, the ITR-U filing window is from 1st April 2027 to 31st March 2031. This section outlines when ITR-U can be filed, eligibility criteria, and guidelines for managing additional tax liabilities associated with updated returns.

Budget 2026 Amendments: Updated Rules for Filing ITR-U and Loss Adjustments
As part of the Budget 2026 proposals, taxpayers are now allowed to file an Updated Income Tax Return (ITR-U) even after the commencement of re-assessment proceedings, with an additional 10% tax applicable over existing liabilities. This change aims to reduce litigation and simplify compliance, ensuring that the assessing officer refers only to the updated return during reassessments. Furthermore, effective from 1st March 2026, taxpayers can also file ITR-U for claiming reduction of losses from previous years.
TR-U – How to Update and Correct Your Income Tax Returns
Covered under Section 139(8A)
The provisions of ITR-U fall under Section 139(8A) of the Income Tax Act, 1961, allowing taxpayers to correct or update previously filed returns.
Applicable Even After Missing Deadlines
Taxpayers can file ITR-U even if they have missed the deadlines for the original return, revised return, or belated return, ensuring compliance with the Income Tax Department.
Rectifying Errors and Omissions
This form allows taxpayers to update their ITRs by correcting mistakes, reporting unclaimed deductions, or adding omitted income to ensure accurate reporting.
Filing Window
ITR-U can be submitted within four years from the end of the relevant assessment year, providing sufficient time to rectify past filings.
Practical Example
For instance, if an ITR was filed for AY 2026‑27 (FY 2025‑26) and the revised or belated return window was missed, the taxpayer can still submit an ITR-U after 31st March 2027 and up to 31st March 2031, ensuring all corrections are accounted for.

Within 12 months | 25% of additional tax (tax + interest) |

Within 36 months | 60% of additional tax (tax + interest) |

Note: The extended 48-month window gives taxpayers flexibility to correct errors, update returns, and ensure compliance, while applying the appropriate additional tax for late or updated filings.

Steps to Compute Tax Payable for an Updated Return (ITR-U)
While filing ITR-U, the total tax liability is calculated using the following formulas:
Total Income Tax Liability = Tax Payable + Interest + Late Filing Fees + Additional Tax
Net Tax Liability = Total Income Tax Liability − TDS/TCS/Advance Tax/Tax Relief
Breakdown Table for Computation

A | Tax payable on additional income as per modified ITR (Part B-TTI) | Modified ITR submitted with ITR-U | XXXX |
B | Interest on additional income under Sections 234A, 234B, 234C | Modified ITR submitted with ITR-U | XXXX |
C | Late filing fees under Section 234F | Modified ITR submitted with ITR-U | XXXX |
D | Taxes already paid or relief available (TDS/TCS/Advance Tax/Regular Assessment Tax) | — | XXXX |
E | Aggregate tax liability on additional income | A + B + C − D | XXXX |
F | Additional tax applicable for delayed filing under Section 140B (25%, 50%, 60%, 70% depending on months elapsed) | — | XXXX |
G | Net Tax Amount Payable | E + F | XXXX |
Important Notes for FY 2025‑26 (AY 2026‑27):
The ITR-U filing window is from 1st April 2027 to 31st March 2031.
Additional tax under Section 140B depends on the number of months elapsed since the end of the assessment year:
Within 12 months → 25% of additional tax
Within 24 months → 50% of additional tax
Within 36 months → 60% of additional tax
Within 48 months → 70% of additional tax
Ensure that all figures match your previously filed ITR to avoid discrepancies.
Net tax payable is the sum of aggregate tax liability plus additional tax, minus already paid taxes or reliefs.
