Section 117 of the Income-tax Act, 1961: Appointment of Income-tax Authorities
Section 117 identifies who may appoint income-tax authorities, when appointment powers may be delegated, and how supporting executive or ministerial staff may be appointed. The corresponding provision under the Income-tax Act, 2025 is Section 237.
Meaning and purpose of Section 117
The provision belongs to Chapter XIII of the Income-tax Act, 1961, dealing with income-tax authorities. It establishes the statutory framework for appointing officers and staff. The classes of income-tax authorities are set out in Section 116; Section 117 addresses appointment rather than the separate questions of jurisdiction or exercise of investigative powers.
Explanation of Section 117, subsection by subsection
Section 117(1): Central Government's power
The Central Government may appoint such persons as it considers fit to be income-tax authorities. This is the primary statutory power to make appointments under the 1961 Act.
Section 117(2): Delegation of appointment powers
Subject to Central Government rules and orders concerning conditions of service, the Central Government may authorise the Central Board of Direct Taxes (CBDT), a Principal Director General or Director-General, a Principal Chief Commissioner or Chief Commissioner, a Principal Director or Director, or a Principal Commissioner or Commissioner to appoint income-tax authorities below the rank of Assistant Commissioner or Deputy Commissioner.
This does not create an unrestricted appointment power: the relevant authority must be duly authorised and must comply with applicable service rules and orders.
Section 117(3): Supporting staff
An income-tax authority specifically authorised by the CBDT may appoint necessary executive or ministerial staff to assist in carrying out its functions, subject to the Central Government's service rules and orders.
Important statutory terms
| Term | Explanation |
|---|---|
| Central Government | The Union Government exercising statutory appointment and authorisation powers under the relevant income-tax legislation. |
| CBDT or Board | The Central Board of Direct Taxes, constituted under the Central Boards of Revenue Act, 1963, and referred to in the income-tax legislation. |
| Income-tax authorities | Officers and authorities classified under Section 116 of the 1961 Act; corresponding classifications appear in Section 236 of the 2025 Act. |
| Authorisation | Legal permission given by the competent authority to exercise a specified appointment power, subject to statutory limits and service rules. |

Income-tax Act, 2025: Corresponding Section 237
Section 237 of the Income-tax Act, 2025 substantially carries forward the appointment framework: the Central Government may appoint income-tax authorities; specified senior officers and the Board may be authorised to appoint authorities below the rank of Deputy Commissioner or Assistant Commissioner; and Board-authorised authorities may appoint necessary executive or ministerial staff subject to service rules.
The new Act generally took effect on 1 April 2026. Its repeal-and-savings provisions must be considered for older tax years and pending matters. For the operative wording, see the official Section 237 text and the Income-tax Act, 2025 as amended by the Finance Act, 2026.
Appointment is different from jurisdiction and powers
An officer's appointment does not, by itself, establish jurisdiction over every taxpayer or authorise every statutory action. Under the 1961 Act, Section 118 concerns control, Section 119 concerns instructions, Section 120 concerns jurisdiction, and Section 124 addresses Assessing Officers' jurisdiction.
Legislative background
Sections 116, 117 and 118 were substituted by the Direct Tax Laws (Amendment) Act, 1987, with effect from 1 April 1988. The provision was subsequently amended to reflect changes in officer designations and appointment ranks, including amendments effective from 1 October 1998 and changes introduced in 2014 concerning Principal-level designations.
