The PCIT invoked Section 263, holding that the AO’s failure to initiate penalty proceedings under Section 270A rendered the assessment erroneous and prejudicial to Revenue, and directed initiation of penalty proceedings. It further held that initiation of Section 270A penalty proceedings was discretionary based on the AO’s satisfaction, not mandatory. ITAT Finding: The ITAT held that the PCIT failed to establish how the assessment order was erroneous and prejudicial to Revenue. Therefore, mere non-initiation of penalty proceedings could not, by itself, make the assessment order erroneous and prejudicial to the interests of Revenue. Commissioner of Income Tax, (Central) Ahmedabad has erred in not considering fact that the assessment proceedings and penalty proceedings are separate and distinct and for non-initiation of penalty proceedings during assessment proceedings by the Assessing Officer is not an error for which revision proceedings can be invoked.
