“revised return”

An assessee cannot raise a new claim or a claim not made in the original or revised return of income for the first time directly before the Assessing Officer during assessment proceedings.

Appellate authorities can entertain fresh claims or revised computations of income made by an assessee, even if these were not submitted through a revised return of income.

An assessee can make an additional claim for deduction or file a revised computation of income during assessment proceedings, even if a revised return of income has not been filed. Such additional claims or grounds can also be admitted at the appellate stage.

A Commissioner can revise an assessment order under Section 263 if it is erroneous and prejudicial to the interests of the revenue. This includes cases where the Assessing Officer fails to make further inquiries before accepting the assessee's statements in the return.

A penalty under section 271(1)(c) for concealment or furnishing inaccurate particulars of income is not automatically leviable merely because a higher income is declared, even after a search or in a voluntarily revised return. The initial burden to prove concealment or inaccurate particulars lies with the Revenue.

A penalty for concealment of income cannot be levied if an assessee files a revised return to buy peace and avoid litigation, and the revenue accepts this without objection.

An assessment order becomes erroneous and prejudicial to the revenue under Section 263 if the Assessing Officer fails to conduct a proper inquiry or investigation, even if the return appears prima facie correct. The Income-tax Officer has a duty to investigate and cannot remain passive.

Where no inquiry was conducted by the Assessing Officer in passing an assessment order after accepting a revised return, the Commissioner acts within their power under section 263 to direct a fresh assessment.
