A revised return under Section 139(5) of the Income Tax Act is how a taxpayer corrects a mistake in an ITR that has already been filed. The mistake could be an omitted income. It could be a wrong deduction claim. It could be an incorrect TDS credit. It could be a mismatched filing status. Section 139(5) allows the correction to be filed before the end of the relevant assessment year. For AY 2026-27, that deadline is 31 March 2027. It can also be filed before the assessment is completed, whichever comes first. If the original return was filed on time under Section 139(1), multiple revisions are permitted within that window. If the original was a belated return under Section 139(4), only one revision is allowed.
Why Taxpayers in Gujarat End Up Filing a Revised Return
The most common trigger is a mismatch that surfaces after filing. A bank interest certificate arrives after the ITR is submitted. A TDS credit is missing from Form 26AS. A deduction under Chapter VI-A was overlooked. A manufacturing unit in Ahmedabad claimed depreciation on plant and machinery. It may discover after the FY closure that a particular asset did not qualify for the rate claimed. This inflated the loss and reduced the tax liability incorrectly. A Surat textile trader missed a Section 80C investment proof. A life insurance premium was paid in March but the receipt was not issued until April. The trader files the original ITR without the deduction. A revised return is filed once the document is in hand.
Capital gains revisions are particularly common among property sellers. A Vapi real estate developer sold a plot. They claimed Section 54 exemption without the correct cost-of-improvement calculation. They will receive a notice under Section 143(1) if the error inflates the capital loss. Filing a revision before the notice arrives is substantially cheaper than responding to a query. The same logic applies to salaried employees across Rajkot and Jamnagar who receive a revised Form 16 after filing. The additional TDS credit is added through a revised return. If it produces a refund, the acknowledgement typically arrives within weeks of filing.
ITR-U: The Separate Facility for Filing After the Due Date
Section 139(8A) introduced the Updated Return — ITR-U — as a distinct mechanism for voluntarily disclosing income that was not reported in the original return. Unlike Section 139(5), ITR-U can be filed up to 24 months from the end of the relevant assessment year. For AY 2026-27, the window closes on 31 March 2029. The cost of using ITR-U is explicit. Additional tax of 25% of the updated income applies if total income does not exceed ₹50 lakh. Additional tax of 50% applies if it exceeds ₹50 lakh. This is paid via challan 280 before filing. Interest under Sections 234A, 234B, and 234C also accrues on the additional tax liability. In exchange, Section 139(8A)(7) provides immunity from penalty under Sections 270A and 271(1)(c). It does not provide immunity from prosecution under Sections 276C or 276CC for wilful tax evasion.
An ITR-U cannot itself be revised. If a second omission is discovered after filing an ITR-U, a fresh ITR-U for the same AY can be filed within the 24-month window. The additional 25% or 50% tax is paid again on the newly disclosed income. For a business in Bhavnagar that operates across multiple FYs and regularly discovers bank FD interest or dividend income after the filing deadline, the ITR-U window provides a structured path to stay compliant without triggering a penalty.
What Cannot Be Corrected Through Revision
Not every error qualifies for a revised return. A fundamentally incorrect PAN application cannot be corrected this way. A return filed under the wrong income tax category after the deadline has passed cannot be corrected this way. A return submitted by a person who was not eligible to file at all cannot be corrected this way. If the original return was filed under the wrong ITR form — say, ITR-1 when the taxpayer had business income under ITR-3 — the revision must still use the correct form. But the correction is valid only if filed before the AY end. A belated return filed after the Section 139(4) deadline cannot be revised to change the filing category either. In that situation, ITR-U is the only available path.
Section 234F, the late filing fee for belated returns, applies when a revised return is filed after the original due date. This applies even if the original return itself was filed on time. A taxpayer who files a Section 139(1) original return by 31 July but discovers an error in September and files a belated revision will attract the late fee. FinTax24 computes this fee during the scope analysis phase. The additional liability is known before the revised return is submitted, not after.
