Income-Tax Act 2025 is the definitive annotated text of India's new direct tax code, updated to incorporate all amendments introduced by the Finance Act 2026. The 2025 Act is the most consequential restructuring of Indian direct tax law in over six decades, consolidating the old law into 535+ sections across 22 chapters while replacing the previous year/assessment year framework with a unified 'tax year.' Every provision carries a four-dimension annotation covering applicable Rules and Forms, CBDT Circulars and Notifications, judicially noticed words and phrases, and allied law cross-references—with the full text of every cited statute reproduced in the Appendix, making this a truly self-contained desk reference. Three granular cross-reference tables mapping the complete 1961–2025 transition—down to the sub-section and clause level—alongside an inline 'Corresponding Provision' reference under every section, make this the indispensable transition tool for a profession trained under the old Act. Spanning over 1,500 pages and incorporating five legislative instruments, this is the authoritative single-volume reference for every constituent of India's direct tax profession.
