An Updated return can be furnished u/s 139(8A) of the Income Tax Act 1961 by any person, whether or not he has furnished a return under sub-section (1) or sub-section (4) or sub-section (5), for an assessment year (herein referred to as the relevant assessment year), 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 61 at any time within twenty-four months from the end of the relevant assessment year.

The provision of section 139(8A) shall not apply, if the updated return,—

(b) has the effect of decreasing the total tax liability determined on the basis of return furnished under sub-section (1) or sub-section (4) or sub-section (5); or

(c) results in refund or increases the refund due on the basis of return furnished under sub-section (1) or sub-section (4) or sub-section (5), of such person under this Act for the relevant assessment year:

Further, a person shall not be eligible to furnish an updated return under this sub-section, where—

(a) a search has been initiated under section 132 or books of account or other documents or any assets are requisitioned under section 132A in the case of such person; or

(b) a survey has been conducted under section 133A, other than sub-section (2A) of that section, in the case of such person; or

No updated return can be furnished by any person for the relevant assessment year, where—

(a) an updated return has been furnished by him under this sub-section for the relevant assessment year; or

(b) any proceeding for assessment or reassessment or recomputation or revision of income under this Act is pending or has been completed for the relevant assessment year in his case; or

Provided also that if any person has sustained a loss in any previous year and has furnished a return of loss in the prescribed form within the time allowed under sub-section (1) and verified in the prescribed manner and containing such other particulars as may be prescribed, he shall be allowed to furnish an updated return where such updated return is a return of income:

Provided also that if the loss or any part thereof carried forward under Chapter VI or unabsorbed depreciation carried forward under sub-section (2) of section 32 or tax credit carried forward under section 115JAA or under section 115JD is to be reduced for any subsequent previous year as a result of furnishing of return of income under this sub-section for a previous year, an updated return shall be furnished for each such subsequent previous year.

Updated return under section 139(8A) permits filing additional income return unless barred by search, survey, assessment, or specified information. An updated return under section 139(8A) allows any person to furnish Form 61 for the relevant assessment year within twenty-four months, but excludes returns of loss, any filing that decreases tax liability or increases refunds relative to earlier returns, and is barred where searches, requisitions, surveys, prior updated returns, pending or completed assessment proceedings, communicated information under specified anti money laundering or international exchange provisions, prosecution initiation, or Board notified classes apply; provisos preserve filing where a timely verified return of loss was earlier filed and require subsequent updated returns to reflect reductions in carry forward losses, depreciation or tax credits.
