Missed your ITR? Forgot to declare an income source? Got a Section 148 notice? Don't panic — file an Updated Return (ITR-U) under Section 139(8A) of the Income Tax Act, 1961 (and Section 263(6) of the Income Tax Act, 2025, w.e.f. 1 April 2026). With the Finance Act 2025 extension, you now have up to 48 months from the end of the relevant Assessment Year to come clean — voluntarily and lawfully.
Last date to file Updated Return for each AY
The Updated Return is a unique compliance window — a second chance for honest taxpayers to correct genuine errors and declare missed income, without facing the harsh consequences of reassessment, scrutiny, or prosecution.
Introduced by Finance Act, 2022 w.e.f. AY 2020-21 under Section 139(8A) of the Income Tax Act, 1961, with corresponding additional tax provisions under Section 140B. The new Income Tax Act, 2025 consolidates these into Section 263(6) read with the relevant additional-tax provisions, effective 1 April 2026.
Old & New ActThe Finance Act, 2025 extended the filing window from 24 months to 48 months from the end of the relevant Assessment Year, effective 1 April 2025. This means you now have a full four-year voluntary correction window — the longest taxpayer-friendly window in Indian direct-tax history.
Budget 2025ITR-U is strictly an upward instrument. It cannot be used to claim a refund, increase an existing refund, reduce already-declared tax liability, or convert an income return into a loss return. It exists solely to declare additional tax liability.
ImportantOnly one ITR-U is permitted per Assessment Year. There is no second attempt. Therefore, every omission, every missed income, every error must be addressed in a single comprehensive filing — making expert CA review essential before submission.
No Re-doFiling attracts progressive additional tax on the aggregate of tax + interest payable: 25% within 12 months, 50% in 12-24 months, 60% in 24-36 months, 70% in 36-48 months. +10% premium if filed after a reassessment notice (Budget 2026).
Section 140BBy filing ITR-U voluntarily, you avoid scrutiny u/s 143(3), best-judgement assessment u/s 144, income-escaping assessment u/s 147, and most importantly the 50%–200% penalty u/s 270A for under-reporting/misreporting. It is the cheapest way to come clean.
Litigation ShieldThe Income Tax Act, 2025 (effective 1 April 2026) consolidates Section 139's sub-sections into a unified Section 263. Updated returns for AY 2026-27 onwards are governed by the new Act; AY 2025-26 and earlier continue under the 1961 Act by virtue of Section 536(2)(c) of the new Act.
Applies up to AY 2025-26 (FY 2024-25)
Applies from AY 2026-27 (Tax Year 2026-27)
Filing ITR-U attracts a progressive additional tax on the aggregate of tax + interest payable on the additional income. Rates are calibrated to encourage early correction.

Very ExpensiveThree powerful tools designed by CA Alok Kumar to help you assess your ITR-U liability, eligibility, and the right return option for your situation.
Compute exact additional tax payable u/s 140B (or its IT Act 2025 equivalent) based on filing date and undisclosed income. Updated for Budget 2025 (48-month window) and Budget 2026 (reassessment premium).
Answer 7 simple questions to instantly find out whether you are eligible to file an Updated Return — and which scenario applies to your case.
1. Has the 48-month window from end of relevant AY expired?
2. Does your updated return result in additional tax payable (i.e., not a refund/loss/nil)?
3. Have you already filed an ITR-U for this AY?
4. Has a search u/s 132 or requisition u/s 132A been initiated against you?
5. Is a survey u/s 133A (other than 133A(2A)) ongoing?
6. Has any prosecution proceeding been initiated for this AY?
7. Has assessment / reassessment / revision proceeding been completed for this AY?
Three return types, three windows, three different costs. Pick the right one for your situation. The general rule: if revised window is open, that is almost always the better option.

The legislative architecture under Section 139(8A) (and Section 263(6) of the new Act) is permissive on assessee-class but restrictive on circumstances.
All assessee classes — covered scenarios
Statutory bars under Section 139(8A) proviso
Eight high-frequency scenarios from CA Alok Kumar's 25+ years of practice — and the right approach for each.
Tenant deducted no TDS, you didn't get a Form 16A, and the rental income simply slipped your mind. AIS now reflects bank credits — disclose via ITR-U before the AO sees it.
Most CommonSold mutual funds, stocks, or property and forgot to report. With AIS auto-populating broker data, mismatch with ITR is a red flag. ITR-U is the cleanest fix.
FrequentSB interest beyond ₹10,000/40,000 (80TTA/80TTB), FD interest, RD interest — frequently under-reported. Form 26AS and AIS catch this automatically.
CommonForeign dividends, ESOPs from US parent, Schedule FA non-disclosure — ITR-U with rectification is far cheaper than Black Money Act prosecution.
High RiskSide income from consulting, content, Upwork, Fiverr, online tutoring — payment-app data is now shared with the I-T Department. Voluntary disclosure is wise.
TrendingReassessment notice received — Budget 2026 now allows ITR-U with 10% premium. Once filed, AO can refer only to the updated return; no penalty u/s 270A on disclosed income.
Game-ChangerIncome above basic exemption but no return filed — ITR-U lets you regularize multiple years (subject to 48-month limit). Avoids ₹10,000 penalty u/s 271F and prosecution.
RescueCrypto gains taxable @30% u/s 115BBH (Schedule VDA) since AY 2023-24. Many missed this — ITR-U is the prescribed route to disclose and regularize.
ModernA structured, audit-trail-friendly workflow refined over hundreds of ITR-U filings since the provision was introduced in 2022.

A curated reference compendium of the relevant statutory text, departmental notifications, and authoritative judicial guidance shaping ITR-U practice today. For taxpayers, advocates, and fellow professionals.
Any person, whether or not he has furnished a return under sub-section (1) or sub-section (4) or sub-section (5), may furnish an updated return of his income or the income of any other person in respect of which he is assessable under this Act, for the previous year relevant to such assessment year, in the prescribed form, verified in such manner and setting forth such particulars as may be prescribed, at any time within forty-eight months from the end of the relevant assessment year.
Where no return has been furnished or where the return has been furnished, the assessee shall be liable to pay the tax due together with interest and fee payable, along with the additional income-tax computed at twenty-five per cent / fifty per cent / sixty per cent / seventy per cent of the aggregate of tax and interest payable, depending upon the period elapsed from the end of the relevant assessment year.
Any person may furnish an updated return for any tax year, in the prescribed form and manner, within forty-eight months from the end of the relevant tax year, subject to payment of the additional income-tax as prescribed and the restrictions specified in the provisos to this sub-section.
The return of income to be furnished by any person, eligible to file such return under sub-section (8A) of section 139, relating to the assessment year commencing on the 1st day of April, 2020 and subsequent assessment years, shall be in the Form ITR-U and be verified in the manner indicated therein. Companies, political parties, and persons subject to compulsory tax audit u/s 44AB must verify ITR-U through Digital Signature Certificate (DSC); other assessees may verify via DSC or Electronic Verification Code (EVC).
The first notification giving effect to ITR-U. Inserted Rule 12AC and prescribed Form ITR-U for filing updated returns from AY 2020-21 onwards. Specified the categories of persons who must verify ITR-U through DSC vs EVC.
Substituted the existing Form ITR-U with a new comprehensive form to align with the 48-month window introduced by Finance Act 2025. Added Column 10 in Part B-ATI for additional income-tax liability where ITR-U is filed in response to a notice u/s 148 (35%/60%/70%/80%).
Inserted sub-section (8A) in Section 139 and a new Section 140B to provide the substantive law for filing updated returns. Initial window was 24 months from end of relevant AY, with 25%/50% additional tax slabs.
Extended the ITR-U filing window from 24 to 48 months. Added new slabs of 60% (24-36 months) and 70% (36-48 months). Introduced the proviso barring ITR-U where notice u/s 148A is issued after 36 months from end of AY (with carve-out if 148A(3) order says it's not a fit case).
(a) ITR-U permitted after a reassessment notice has been issued, with 10% additional premium over slab rate; (b) ITR-U can now reduce carried-forward losses or unabsorbed depreciation (effective 1 March 2026); (c) Confirmed no separate filing fee for ITR-U beyond additional tax.
The Income Tax Department periodically enables ITR-U filing utilities for specific Assessment Years (e.g., AYs 2021-22 & 2022-23 enabled for ITR-1, 2, 3, 4 in phased rollouts). Excel-based JSON utility requires the .NET framework; online filing now permitted for ITR-1 and ITR-2.
The Department has actively urged taxpayers via SMS, email and AIS portal communications to file ITR-U where the Annual Information Statement (AIS) reveals undisclosed transactions. The "Compliance Portal" specifically flags non-filers and under-reporters.
Eased and streamlined the processing timelines for electronically filed returns, indirectly benefiting ITR-U filings by reducing pendency and accelerating intimation u/s 143(1).
The landmark ruling that re-shaped the post-148A reassessment landscape. Notices issued under the old Section 148 regime between 1 April and 30 June 2021 were treated as show-cause notices under the new Section 148A. Significance for ITR-U: Establishes the constitutional and procedural primacy of Section 148A — directly relevant to the ITR-U bar where notice u/s 148A is issued after 36 months from end of AY.
Clarified the surviving period available to the AO for issuance of fresh 148 notices post-Ashish Agarwal. Significance for ITR-U: Reinforces strict outer time-limits within which reassessment can be initiated — taxpayers operating within those windows can plan ITR-U filings strategically to invoke Budget 2026's 10% premium route while avoiding 270A penalty.
Several High Courts (Bombay, Delhi, Madras) have, in cases of refund-claim returns filed beyond statutory time, allowed condonation u/s 119(2)(b). Significance for ITR-U: Where ITR-U is not available (e.g., genuine refund cases), the Section 119(2)(b) condonation route remains viable — a critical alternative practitioners must keep on the table.
Multiple ITAT rulings have set aside reassessment orders where mandatory procedural safeguards (notice u/s 148A, opportunity of hearing) were not followed. Significance for ITR-U: Reinforces taxpayer's procedural shield. A properly filed ITR-U, with full disclosure, often forecloses subsequent reassessment under Section 147 because the AO can only refer to the updated return.
It is settled law that voluntary disclosure of income before detection by the Department materially reduces (or extinguishes) the imposition of concealment / under-reporting penalty. Significance for ITR-U: A correctly filed ITR-U is treated as voluntary disclosure — the additional tax (25%-70%) under Section 140B operates in lieu of Section 270A penalty (50%-200%).
The proviso to Section 139(8A) is unambiguous: ITR-U cannot result in a return of loss, claim of refund, or reduction in tax liability. Any attempt to file such an updated return is rendered invalid. Significance for ITR-U: Where the taxpayer's genuine claim is for refund/loss, the proper remedy is rectification u/s 154, revised return (if window open), or condonation u/s 119(2)(b) — not ITR-U.
Where ITR-U for one AY results in reduction of carried-forward loss, unabsorbed depreciation, or tax credit affecting subsequent AY, an ITR-U must be filed for each affected subsequent AY. Significance for ITR-U: Practitioners must trace forward all consequential adjustments — failure to update subsequent AYs can constitute under-reporting separately for those years.
An updated return filed without payment of the entire tax + interest + late fee + additional tax (computed under Section 140B) is treated as defective / invalid. Significance for ITR-U: Unlike Section 139(1) returns, ITR-U is conditional on full upfront tax payment via Challan 280 (Self-Assessment Tax u/s 140B). The challan details (BSR, date, amount) must be furnished within the form.
Answers to the most common questions from taxpayers, businesses, NRIs, and professionals seeking ITR-U guidance.
ITR-U (Updated Return) is a special return form that lets taxpayers correct errors or omissions in previously filed returns, or file a return that was never filed. Introduced by Finance Act 2022 under Section 139(8A) of the Income Tax Act, 1961, it is now codified under Section 263(6) of the Income Tax Act, 2025 (effective 1 April 2026 for Tax Year 2026-27 onwards). Finance Act 2025 extended the filing window from 24 to 48 months.
The last date to file ITR-U is 48 months from the end of the relevant AY:
Additional tax under Section 140B is computed on (Tax payable + Interest u/s 234A/B/C) on the additional income disclosed. The percentage depends on filing date measured from the end of the relevant AY: 25% within 12 months, 50% in 12-24 months, 60% in 24-36 months, 70% in 36-48 months. Example: Additional tax ₹50,000 + interest ₹8,000 = ₹58,000. If filed in 18th month (50% slab): additional tax = 50% × ₹58,000 = ₹29,000. Total ITR-U liability = ₹58,000 + ₹29,000 = ₹87,000.
Yes — but only post Budget 2026. Earlier, a Section 148 notice barred ITR-U filing. The Budget 2026 amendment now permits ITR-U even after a reassessment notice is issued, with an additional 10% premium on top of the slab rate. This is a major taxpayer-friendly change. Once filed, the AO can only refer to the updated return, and no penalty u/s 270A (under-reporting/misreporting) applies on the disclosed income — making it a powerful litigation-mitigation tool.
No. ITR-U is a one-way upward instrument. It cannot be used to: (a) claim a refund, (b) increase an existing refund, (c) reduce tax liability declared in the original return, (d) convert an income return into a loss return, or (e) increase carried-forward losses. ITR-U exists solely to declare additional tax liability.
Only once per Assessment Year. There is no facility to revise an ITR-U. Hence, every additional income, omission, and correction must be incorporated in a single, comprehensive ITR-U filing. Expert CA review is therefore essential — a missed item cannot be added later.
The applicable ITR form (ITR-1 to ITR-7) for that AY is filled fully along with Part-A General Information of ITR-U and Part-B-ATI (Additional Tax computation). You can also change the ITR form if your additional income now requires a different form — e.g., shift from ITR-1 to ITR-2 if capital gains are added.
Yes — effective 1 March 2026, ITR-U can be filed to reduce carried-forward losses or unabsorbed depreciation arising from a previous year's return. Note: ITR-U cannot create or increase losses — only reduce them. If a loss reduction in one AY affects a subsequent AY's carry-forward, ITR-U must be filed for each affected subsequent year as well.
Unfortunately, ITR-U cannot be used to claim missed deductions because doing so would reduce tax liability. The remedies are: (a) revised return u/s 139(5) if window is open, (b) rectification u/s 154 if it qualifies as a "mistake apparent from record", or (c) writing to CPC/AO with a justification. CA Alok Kumar can advise on the appropriate remedy.
For most cases: (1) PAN & Aadhaar, (2) Original ITR acknowledgement (if filed), (3) AIS & TIS download, (4) Form 26AS, (5) Bank statements for the FY, (6) Form 16/16A from deductors, (7) Capital gains statements (broker), (8) Foreign income/asset documents, (9) Sale deeds for property, (10) Any I-T notice received. We send a checklist tailored to your case after the consultation.
If the original ITR was never filed and you are now filing ITR-U, late fee u/s 234F applies: ₹1,000 if total income ≤ ₹5 lakh, and ₹5,000 if total income > ₹5 lakh. This is over and above the additional tax (25%/50%/60%/70%) and the regular tax + interest u/s 234A/B/C.
ITR-U is a one-shot instrument. Errors cannot be corrected. CA Alok Kumar (FCA, AICA, LLM, AML Specialist) and the team at S.K. Mehta & Co. (est. 1970, 110+ professionals, empaneled with CAG, RBI & IRDA) bring 25+ years of tax-litigation experience. We perform exhaustive AIS/TIS/26AS reconciliation, accurate additional-tax computation, and ensure your filing is complete, defensible and final. For notice cases (Sec 148/247), we also handle representation end-to-end.
For AY 2021-22 (FY 2020-21), the absolute final date is 31 March 2026 — that's just months away. For other AYs, every passing month moves you to a higher additional-tax slab. Speak to CA Alok Kumar today to discuss your case and the right compliance strategy.
