Revised Return (Section 139(5))
A revised return under Section 139(5) allows a taxpayer to correct any omission or wrong statement made in an originally filed return, and can be filed before 31 December of the relevant assessment year or before completion of assessment, whichever is earlier.
Section 139(5) provides taxpayers with a correction mechanism to rectify genuine errors or omissions discovered after the original return was filed. The provision is available regardless of whether the original return was filed on time or belatedly under Section 139(4) — though a defective return under Section 139(9) that has not been rectified cannot be treated as a valid return for Section 139(5) purposes until the defect is cured.
The window for filing a revised return is 31 December of the assessment year (the same as the belated return window), or before the completion of assessment proceedings under Section 143(1) or Section 143(3), whichever is earlier. Practically, once an assessment order is passed, the revised return option is no longer available, and the taxpayer must use other mechanisms such as rectification under Section 154 or appeal under Section 246A.
There is no limit on the number of times a return can be revised — a taxpayer can file multiple revised returns for the same assessment year, with the most recently filed revised return superseding all prior versions. This flexibility is important for taxpayers who receive revised Form 26AS or AIS data, discover additional income sources, or receive capital gains statements from their broker or mutual fund registrar after the original filing date.
A revised return can increase or decrease the declared income. It is commonly used to: include exempt income inadvertently omitted (which affects reported figures without changing tax liability); claim deductions missed in the original return; correct bank account details for refund routing; add or remove income heads such as interest income, rental income, or capital gains; and update the tax payment details if advance tax payments were made but not reflected.
One important restriction: a revised return should be filed only to correct a genuine omission or wrong statement — it cannot be used as a tool for tax planning after the fact by restructuring income or claiming deductions that were intentionally not taken. Courts have held that revising returns to retroactively elect a different method of accounting or switch income heads constitutes abuse of the provision. The department can and does scrutinise revised returns for such attempts, particularly when the revision results in a significant tax reduction.
