How to revise
On the e-filing portal, choose ‘revised return’, quote your original acknowledgement number, correct the entries and re-submit. Then e-verify the revised return.
Deadline
Up to 31 December of the assessment year, or before your return is assessed — whichever is earlier.
When to revise, and what to watch
A revised return is the clean way to fix almost any genuine error in a filed return — an omitted interest income, a deduction missed, a wrong figure, even a wrong ITR form — and you can revise more than once if needed, each revision replacing the last. It’s available whether the original was filed on time or belatedly, up to 31 December of the assessment year or before the assessment is completed, whichever is earlier. There’s no fee merely to revise, though if the correction increases your tax you pay that tax with interest. Two practical points: always quote the original return’s acknowledgement number so the revision links correctly, and e-verify the revised return — an unverified revision doesn’t count, and the original then stands. Revising before the department picks the return for processing is smoother than after. If the change is only a small mismatch in a return already processed, sometimes a rectification under Section 154 is the right route instead; but for a substantive error caught in time, the revised return under Section 139(5) is the standard fix. Keep the supporting documents for whatever you changed, in case the revised figures are later queried.
