The New Income Tax Act 2025, which received Presidential assent on August 21, 2025, formally replaces the Income Tax Act 1961 from April 1, 2026. The six-decade-old law had accumulated over 800 amendments, making it complex and difficult to navigate for taxpayers and administrators alike.

The new legislation aims to simplify the tax system by reducing the total number of sections from 819 to 536, removing redundant provisions, rationalizing exemptions, and streamlining compliance procedures. Key changes include simplified language for better comprehension, consolidation of similar provisions, removal of obsolete references, and a modernized framework for digital-age taxation. The government expects this reform to reduce litigation, improve voluntary compliance, and make the tax regime more transparent and taxpayer-friendly.

The transition is supported by updated forms, revised ITR filing systems, and extensive awareness campaigns by the CBDT to help assessees understand the new provisions.
