Current legal position from 1 April 2026:

The Income-tax Act, 2025 is the current statute for tax years beginning on or after 1 April 2026. However, Section 536(2)(c) expressly preserves the Income-tax Act, 1961 for pending proceedings and for proceedings initiated on or after 1 April 2026 in respect of tax years beginning before that date. Accordingly, assessment and reassessment proceedings for earlier years - including proceedings under Sections 147 to 150 where applicable - continue under the 1961 Act and its procedural and limitation rules.

Authorities, Information & Return Filing - Sections 135 to 140A

Inquiry, Valuation & Assessment - Sections 142 to 145B

Reassessment & Limitation - Sections 147 to 150
