Read on 13 November 2026. The Income-tax Act, 2025 came into force on 1 April 2026 (section 1(3)); the 1961 Act continues to apply to tax years before that (section 536 and the CBDT's FAQs). The mapping comes from the department's navigator, which was drawn up for the Bill, and each new number was checked against the enacted Act; rows that could not be checked are marked. This site is independent and not connected with the Income Tax Department; it is a reading aid, not tax advice.
