Chapter XXIII of the Income-tax Act, 2025 runs from section 499 to section 536 and covers miscellaneous. Its 38 sections replace 55 sections of the Income-tax Act, 1961. This guide gives the complete section-by-section mapping between the two Acts.
What Chapter XXIII covers
Chapter XXIII is the miscellaneous chapter — service of notice, statements of financial transactions, the annual information statement, authorised representatives, rule-making powers, and the repeal and savings provision that governs the transition itself.
Chapter XXIII contains 38 sections (sections 499 to 536). Between them they carry forward the substance of 55 sections of the Income-tax Act, 1961.
The Income-tax Act, 2025 received Presidential assent on 21 August 2025 and takes effect from 1 April 2026. The Income-tax Act, 1961 continues to govern every tax year up to 31 March 2026, and all assessments, appeals, penalties and prosecutions relating to those years are completed under the old Act by virtue of the repeal and savings provision in section 536. The mapping on this page is drawn from the section-wise concordance published with the Act, including the corrigenda notified in the Gazette on 3 September 2025.
What changed in Chapter XXIII
- Section 536 is the repeal and savings provision (old section 297). This is the section that keeps the 1961 Act alive for every tax year up to 31 March 2026 and for all proceedings relating to them.
- Section 509 is a new obligation to furnish information on crypto-asset transactions, carrying section 285BAA.
- Section 508 is the SFT obligation (old section 285BA) and section 510 is the annual information statement (old section 285BB).
- Section 515 carries section 288, appearance by an authorised representative, and section 516 carries the rounding-off rules of sections 288A and 288B.
- Section 533 is the rule-making power (old section 295), under which the Income-tax Rules for the new Act are notified.

How to use this mapping
- Working on a year up to 2025-26? Use the 1961 section in the right-hand column. The old Act governs those years under section 536.
- Working on tax year 2026-27 onwards? Use the new section number in the left-hand column, and read the section text rather than assuming the old provision was copied verbatim.
- Drafting a reply or an appeal? Cite the section that applies to the year in dispute, not the section in force when you are writing.
- Updating templates and software? Sections that merged — shown where one new section maps to several old ones — need the most attention, because a single new provision now carries what were separate conditions.
This page is a structural mapping guide, not tax advice. A corresponding section is not always an identical section — several provisions were merged, split or re-worded when they were carried over. Always read the actual text of the new section before relying on it, and check for later amendments, rules and CBDT notifications.
