Assessing Officer jurisdiction defined by place of business or residence; intra departmental determination and strict time bars follow.
Section 242 defines Assessing Officer jurisdiction vested by directions/orders under section 241(1)-(3): jurisdiction for businesses attaches to the place of business or principal place, and for others to residence. Jurisdictional disputes are to be determined by specified income tax authorities or, where those authorities disagree, by the Board or a Board designated authority. The section bars late challenges to jurisdiction by reference to specified notice periods and assessment completion events, requires AOs to refer unresolved timely challenges for departmental determination before assessing, and preserves AO powers over income within the vested area; the enacted text omits certain cross references present in the originating bill.
