July 2026 Financial and Tax Rule Changes: Income-tax Act 2025, SEBI T+0 and Green Hydrogen Certification
July 2026 financial and tax rule changes take effect as FY 2026-27 Q2 opens: the Income-tax Act 2025 regime, SEBI's optional T+0 settlement, and a live Green Hydrogen Certification portal. Relevant for UPSC and state PSC GS Paper 3.
- The Income-tax Act, 2025 replaced the 65-year-old Income-tax Act, 1961 as India's principal direct-tax statute, in force from 1 April 2026 and applicable from Tax Year 2026-27.
- The 2025 Act does not change TDS/TCS rates — it renumbers provisions into code-based references and consolidates returns into a single form, a compliance simplification.
- The 'Previous Year / Assessment Year' pair is replaced by a single unified concept called the 'Tax Year'.
