CLOSING NOTE — RULES 2026 SERIES (Volumes I-XI)

This 11-volume series traverses the Income-tax Rules, 2026 from Rule 1 to Rule 333, mapping every Rule to its corresponding 1962-Rule source and to the implementing section of the Income-tax Act, 2025. The substantive content of every Rule has been preserved by the CBDT in the post-2026 Rules; the renumbering, simplification, and alignment with the 2025 Act's section-numbering are the principal drafting innovations.

The migration from the 1962 Rules to the 2026 Rules affects the following:

Internal cross-references, working paper templates, opinion templates, audit workings, and tax-software code move from old Rule numbers to new — a multi-quarter exercise commencing 1 April 2026.
Form numbering changes — Forms in Appendix III; gradual roll-out by CBDT, with an old-to-new Form mapping circular.
Rates and methods carried into the new Rules: depreciation rates (Rule 25), perquisite valuation (Rule 15), FMV methods (Rules 56-57), TP methods (Rules 77-84), Safe Harbour margins (Rules 86-102), FTC mechanics (Rule 76).
The 23-volume Act commentary is the companion — every Rule cites the implementing Act section; back-mapping each Act section's Volume to its Rule(s) is the next phase of this commentary series.
CBDT issuances — Forms (Appendix III), notifications, circulars — follow under the new sections; section 536 of the Act keeps existing instruments alive in the interim.
