Rule 1 of the Income-tax Rules, 1962: Short Title and Commencement

Updated: 10 October 2026 | Historical rule and current legal position

Rule 1 established the official name and commencement date of the Income-tax Rules, 1962. Although the rules began operating on 1 April 1962, the Income-tax Rules, 2026 now govern the new statutory framework from 1 April 2026, subject to transitional provisions for earlier tax years.

Current legal position: The Income-tax Act, 2025 and Income-tax Rules, 2026 took effect on 1 April 2026. The earlier law remains relevant for tax years beginning before that date, including returns, assessments, appeals and other proceedings relating to those years.

Text of Rule 1: Short Title and Commencement

Part I - Preliminary

1. Short title and commencement

(1) These rules may be called the Income-tax Rules, 1962.

(2) They shall come into force on the 1st day of April, 1962.

Legal authority for the 1962 Rules

The Income-tax Rules, 1962 were originally made by the Central Board of Revenue in exercise of powers conferred by section 295 of the Income-tax Act, 1961 (43 of 1961), together with rule 15 of Part A, rule 11 of Part B and rule 9 of Part C of the Fourth Schedule to that Act. The original notification was S.O. 969, dated 26 March 1962.

Section 295 empowered the making of rules to implement the Income-tax Act, 1961. Rule 1 itself is introductory: it identifies the rules and states their effective date; it does not prescribe tax rates, exemptions or return-filing requirements.

Meaning and significance of Rule 1

Short title: Sub-rule (1) provides the formal citation, "Income-tax Rules, 1962", used in legislation, notifications, legal documents and tax proceedings.

Commencement: Sub-rule (2) specifies 1 April 1962 as the date on which the rules came into force. Individual amendments introduced later may have their own effective dates and application provisions.

What changed from 1 April 2026?

The Central Board of Direct Taxes notified the Income-tax Rules, 2026 by G.S.R. 198(E), dated 20 March 2026, under section 533 of the Income-tax Act, 2025. Rule 1 of the 2026 Rules gives them their short title and fixes their commencement as 1 April 2026.

Under the transitional framework, the Income-tax Act, 1961 continues to govern tax years beginning before 1 April 2026. For example, income-tax returns for assessment year 2026-27, relating to the preceding financial year, are governed by the earlier framework and applicable return forms. Proceedings concerning earlier periods also continue under the relevant saved provisions.

Consequently, Rule 1 of the 1962 Rules remains useful when interpreting historical obligations and proceedings. For tax years beginning on or after 1 April 2026, readers should consult the Income-tax Act, 2025 and the Income-tax Rules, 2026.
