Belated, Revised and Updated Income Tax Return – ITR-U Explained for AY 2026-27

Missing the original income-tax return filing deadline or discovering an error after filing does not always mean that the taxpayer has lost every opportunity to correct the position. Depending on the circumstances and timing, the Income-tax Act provides different mechanisms such as a belated return, revised return and updated return (ITR-U).

These three options serve different purposes. A belated return is generally used where the original return was not filed within the prescribed due date. A revised return is used to correct an omission or wrong statement in an already filed return. An updated return provides an extended compliance opportunity in specified circumstances, generally where additional income or tax needs to be reported.

EzyBiz India Consulting LLP assists individuals, professionals, business owners, NRIs and other taxpayers with late or corrective return filing through our ITR Filing Services in India.

Belated vs Revised vs Updated ITR – What Is the Difference?

Belated Return – When the Original Due Date Is Missed

A belated return is generally filed where a taxpayer was required or otherwise eligible to furnish an income-tax return but did not file it within the original due date.

The return is filed after the original deadline but within the statutory time allowed for a belated return.

Revised Return – When an Earlier Return Contains an Error

A revised return is used where the taxpayer has already filed an eligible original or belated return but subsequently discovers an omission, incorrect statement or other error requiring correction.

The revised return effectively replaces the earlier return for the relevant assessment year.

Updated Return – Extended Opportunity to Disclose Additional Income

An updated return, commonly referred to as ITR-U, provides an extended opportunity to correct certain tax positions even after the normal belated or revised return period has expired.

However, ITR-U is subject to important restrictions and additional tax consequences and cannot be used simply to obtain a higher refund or reduce the taxpayer’s tax liability.

Important Deadlines for AY 2026-27

Belated Return Deadline – 31 December 2026

For Assessment Year 2026-27, a belated return under section 139(4) of the Income-tax Act, 1961 may generally be filed up to 31 December 2026 or before completion of assessment, whichever is earlier.

The Income Tax Department explains the AY 2026-27 transition and return-filing position in its Income Tax Returns FAQs.

Revised Return Deadline – 31 March 2027

From AY 2026-27 onwards, the time for filing a revised return has been extended up to the end of the relevant assessment year.

Accordingly, an eligible revised return for AY 2026-27 can generally be filed up to 31 March 2027 or before completion of assessment, whichever is earlier.

Updated Return – Extended Period Up to 48 Months

The updated-return mechanism under section 139(8A) permits eligible taxpayers to file an updated return within 48 months from the end of the relevant assessment year, subject to the statutory conditions.

The extended 48-month window significantly increases the period during which certain past tax omissions may be voluntarily corrected.

What Is a Belated Income Tax Return?

Return Filed After the Original Due Date

A belated return is a return furnished after the prescribed original filing deadline but within the period allowed under section 139(4).

It is therefore relevant where the taxpayer did not file the original return on time.

Belated Return Can Cover Different Types of Taxpayers

Individuals, professionals, businesses and other taxpayers may need to use the belated-return mechanism depending on their filing obligations and applicable due dates.

The correct ITR form must still be selected based on the taxpayer’s income and status.

Select the Correct ITR Form Even for a Belated Return

Filing late does not change the underlying ITR form that applies to the taxpayer.

For guidance on ITR-1 to ITR-7, see our detailed guide on Which ITR Form Should You File?.

Consequences of Filing a Belated Return

Late Filing Fee Under Section 234F

For AY 2026-27, a late filing fee under section 234F may apply where the return is filed after the prescribed due date.

The Income Tax Department states that the fee is:

• ₹1,000 where total income does not exceed ₹5 lakh; and
• ₹5,000 in other applicable cases.

Interest May Also Apply

Interest under the applicable income-tax provisions may arise where tax remains unpaid beyond the statutory due dates.

The final amount payable depends on the taxpayer’s tax liability, TDS, advance tax and timing of payment.

Carry-Forward of Certain Losses May Be Affected

Delay in filing can affect the ability to carry forward certain categories of losses where the law requires the return to be filed within the original due date.

Taxpayers with business losses or capital losses should therefore examine the position carefully before assuming that a belated return produces the same result as a timely return.

What Is a Revised Income Tax Return?

Correcting an Omission or Wrong Statement

A revised return is appropriate where an eligible earlier return has already been filed and the taxpayer later discovers an omission or incorrect statement.

Examples include missing income, incorrect deductions, wrong bank details, incorrect capital gains or an error in another part of the return.

A Revised Return Replaces the Earlier Return

Once a valid revised return is filed, the revised information becomes the relevant return information for processing, subject to the applicable law.

The taxpayer should therefore ensure that the revised return contains the complete and correct position rather than merely the specific item being corrected.

More Than One Revision May Be Possible Within the Time Limit

Where legally permissible, a taxpayer discovering another error after filing a revised return may need to file another revised return within the applicable statutory deadline.

The final revised return should contain all correct income, deductions, taxes and disclosures.

Fee for Revised Return Filed After 31 December 2026

No Section 234I Fee Up to 31 December in Applicable Cases

For AY 2026-27 onwards, the revised-return period extends beyond 31 December up to 31 March of the relevant assessment year. Where an eligible revised return is filed after 31 December and up to 31 March, the additional fee under section 234I applies.

₹1,000 Fee Where Total Income Does Not Exceed ₹5 Lakh

Where section 234I applies and total income does not exceed ₹5 lakh, the prescribed fee is ₹1,000.

₹5,000 Fee in Other Cases

Where the revised return is filed during the applicable extended period and total income exceeds ₹5 lakh, the prescribed section 234I fee is ₹5,000.

The Income Tax Department explains the revised-return fee in its ITR filing FAQs.

What Errors Can Be Corrected Through a Revised Return?

Income Omitted From the Original Return

If salary, interest, dividend, rental income, capital gains or another taxable receipt was missed, the taxpayer may need to consider filing a revised return within the permitted time.

Incorrect Deductions or Exemptions

A taxpayer may discover that an eligible deduction was omitted or that an incorrect deduction or exemption was claimed.

The revised return should reflect the legally correct position supported by appropriate documentation.

Wrong ITR Form or Disclosure

In some circumstances, the taxpayer may realise that the wrong return form or incorrect schedule was used.

The appropriate corrective action should be evaluated based on the specific error and available filing period.

AIS and Form 26AS Mismatches

A revised return may become relevant where reconciliation of Form 26AS, AIS or TIS reveals an omission or incorrect tax credit in the originally filed return.

See our detailed guide on Form 26AS, AIS and TIS for ITR Filing in India.

What Is an Updated Return or ITR-U?

Extended Voluntary Compliance Mechanism

An updated return allows an eligible taxpayer to furnish an updated income-tax return even where the normal original, belated or revised filing period is no longer available.

The mechanism is intended to encourage voluntary disclosure and correction of additional taxable income.

ITR-U Can Be Filed Even if No Earlier Return Was Filed

An eligible taxpayer may be able to file an updated return even where no original, belated or revised return was previously filed for the relevant assessment year.

The tax, fee, interest and additional tax consequences will depend on the circumstances.

Applicable ITR Form Is Used With Updated-Return Schedules

ITR-U is not a substitute for determining the underlying applicable ITR form.

The taxpayer uses the relevant ITR form applicable to the assessment year together with the prescribed updated-return information and schedules.

Relevant return utilities are available on the Income Tax Department’s ITR Downloads page.

Who Can File an Updated Return?

Taxpayer Who Missed Reporting Additional Income

ITR-U may be useful where an eligible taxpayer later discovers that taxable income was omitted from the earlier return.

Examples may include interest, property income, capital gains, business receipts or other taxable income that was not previously reported.

Taxpayer Who Did Not File an Earlier Return

Subject to the statutory conditions, a taxpayer who did not file an original or belated return may also use the updated-return mechanism within the permitted period.

Taxpayer Correcting Certain Tax Positions

An updated return may also be relevant where income was reported under an incorrect head, the applicable tax rate was incorrectly applied or certain carried-forward items require correction, depending on the facts and eligibility conditions.

When Can an Updated Return Not Be Filed?

ITR-U Cannot Be Used to Create or Increase a Refund

An updated return generally cannot be used where the result would be a refund or an increase in the refund previously determined.

Accordingly, ITR-U should not be treated as a general mechanism for claiming an old missed refund.

ITR-U Cannot Normally Be Used to Reduce Tax Liability

An updated return cannot ordinarily be used where it decreases the total tax liability compared with the earlier return.

The mechanism is primarily designed for voluntary reporting of additional tax exposure rather than reduction of an already reported liability.

Updated Return Cannot Be a Return of Loss

An updated return cannot be filed where the resulting total income is a loss, subject to the detailed statutory provisions.

Other Statutory Restrictions Can Apply

Restrictions can also arise in cases involving search, requisition, specified surveys, assessments, reassessments, prosecution, information received under specified laws or tax treaties and other circumstances provided by law.

Eligibility should therefore be checked before preparing an ITR-U.

Additional Tax Payable on ITR-U

25% Additional Tax – First 12-Month Period

Where an updated return is furnished within the first applicable 12-month period, additional income-tax is generally calculated at 25% of the aggregate tax and interest payable, subject to the statutory provisions.

50% Additional Tax – 12 to 24 Months

Where the updated return is furnished after 12 months but within 24 months from the end of the relevant assessment year, the additional tax generally increases to 50% of the relevant tax and interest amount.

60% Additional Tax – 24 to 36 Months

Where ITR-U is furnished after 24 months but within 36 months from the end of the relevant assessment year, additional tax is generally 60%.

70% Additional Tax – 36 to 48 Months

Where the updated return is filed after 36 months but within 48 months from the end of the relevant assessment year, additional tax is generally 70%.

Taxpayers should compute the liability carefully because normal tax, interest, applicable fee and additional income-tax may all need to be paid before filing the updated return.

Revised Return vs Updated Return – Which One Should You Use?

Use Revised Return Where the Revision Period Is Still Open

Where an eligible taxpayer has already filed a return and the revised-return period remains available, a revised return is generally the more direct mechanism for correcting an omission or wrong statement.

It does not carry the ITR-U additional tax structure merely because it corrects an earlier return.

ITR-U Is Primarily Relevant After the Normal Correction Window

ITR-U becomes particularly important where the taxpayer later discovers additional taxable income but the ordinary revised-return period is no longer available.

An Updated Return Cannot Be Revised Again

An updated return is subject to stricter statutory conditions and is generally permitted only once for a particular assessment year.

The taxpayer should therefore ensure that the updated return is complete and accurate before submission.

Can I Use ITR-U to Claim a Refund or Report a Loss?

ITR-U Is Not Designed to Increase Refunds

If the correction would result only in an additional or increased refund, ITR-U is generally not the appropriate mechanism.

Other legal remedies, including condonation in genuine hardship cases where applicable, may need to be examined separately.

Loss Returns Have Special Restrictions

An updated return cannot ordinarily result in total income being reported as a loss.

However, adjustments affecting carried-forward losses, unabsorbed depreciation or tax credits may create additional consequences for subsequent years.

Subsequent Years May Also Need Correction

If an updated return reduces carried-forward loss, unabsorbed depreciation, MAT credit or AMT credit available in later years, corrective updated returns for affected subsequent years may also be required.

Review Form 26AS, AIS and TIS Before Correcting Your Return

Identify Income That Was Missed

AIS and TIS can reveal interest, dividends, securities transactions, property transactions and other information that may not have been considered in the earlier return.

Verify TDS and Tax Credits

Form 26AS should be reviewed to confirm the tax deducted or collected and credits available against the taxpayer’s PAN.

Do Not Automatically Copy AIS Figures

AIS is an important reconciliation source but does not by itself determine the final taxable income.

The underlying transaction, books, invoices, bank records and applicable tax law should be reviewed before revising or updating the return.

For a detailed reconciliation process, see our Form 26AS, AIS and TIS for ITR Filing in India.

How to File a Belated, Revised or Updated ITR – Step-by-Step

Step 1 – Identify the Type of Correction Required

Determine whether no return was filed, an earlier return contains an error or the normal filing/revision period has expired.

This helps determine whether a belated, revised or updated return is the appropriate route.

Step 2 – Select the Correct ITR Form

Select the applicable ITR based on taxpayer status and income sources.

Refer to our ITR-1 to ITR-7 Form Selection Guide where required.

Step 3 – Reconcile Income and Taxes

Review Form 16, Form 16A, Form 26AS, AIS, TIS, bank statements, broker reports, property records and other relevant documents.

Step 4 – Calculate Tax, Interest, Fee and Additional Tax

Calculate the liability based on the type of return being filed.

For ITR-U, special additional income-tax may apply in addition to the normal tax and interest.

Step 5 – File and Verify the Return

Submit the return using the applicable electronic filing method and complete the prescribed verification process.

For professional filing support, see our Income Tax Return Filing Services in India.

Common Situations Requiring Belated, Revised or Updated ITR

Forgot to Report Bank Interest

Interest may appear in AIS or bank records even where the taxpayer unintentionally omitted it from the original return.

If the correction period remains open, the appropriate revised or other corrective return should be considered.

Capital Gains Were Not Reported

A taxpayer may overlook gains from shares, mutual funds, property or other capital assets.

The correct capital-gain computation and applicable return mechanism should be determined before correction.

Wrong ITR Form Was Used

A salaried taxpayer may incorrectly use ITR-1 despite having substantial capital gains, or a professional may use a return form that does not properly accommodate business income.

See our guides on ITR Filing for Salaried Individuals and ITR Filing for Freelancers and Professionals.

Incorrect TDS or Refund Claim

A mismatch between the return and Form 26AS may lead to incorrect credit, tax demand or refund issues.

The appropriate correction depends on whether the error lies in the return or in the deductor’s reporting.
