Amendment of Income-tax notifications revises allocation of tax authorities and subordinate jurisdictions under central administration. Under the powers of section 120, the Central Board of Direct Taxes substitutes specified serial numbers and entries in Schedule-I to S.O. 733(E) and Schedule-I to S.O. 734(E), reallocating designations, headquarters and subordinate jurisdictional Commissioner and Director posts for multiple Chief Commissioners of Income-tax and Director Generals of Income-tax (Investigation). The substitutions redefine which Commissioner and Director offices fall under each named Chief Commissioner or Director General and a later corrigendum corrects certain subordinate entries.
