India's landmark tax reform — the Income Tax Act, 2025 — officially came into force on April 1, 2026, replacing the 64-year-old Income Tax Act of 1961. The new legislation consists of 536 sections and 23+ chapters, and represents the most comprehensive overhaul of India's direct tax system since independence.

Background

The Income Tax Act, 1961 had become a maze of more than 50 years of patchwork amendments. The need for a simpler, modern law led to the drafting of the Income Tax Act, 2025, which was passed by Parliament and notified for implementation from April 1, 2026.

Key Structural Changes

  • 'Tax Year' replaces AY/FY: The Act introduces a single 'Tax Year' (April–March) replacing the confusing dual Financial Year (FY) and Assessment Year (AY) system.
  • New Tax Regime as Default: The simplified new tax regime becomes the default under Section 202; taxpayers must opt out to use the old regime.
  • Form 16 replaced by Form 130: A new system-generated Form 130 replaces Form 16 for salaried individuals, improving accuracy.

Tax Slabs and Rebates

  • Zero tax up to ₹12 lakh income via an enhanced rebate of ₹60,000 under Section 87A.
  • For salaried individuals, effective tax-free limit rises to ₹12.75 lakh (with ₹75,000 standard deduction).
  • No change in income tax slab rates for FY 2026-27.

Updated Allowances

  • HRA Exemption Extended: Bengaluru, Pune, Hyderabad, and Ahmedabad now qualify for 50% HRA exemption (previously only Delhi/Mumbai).
  • Children's education allowance raised from ₹100 to ₹3,000 per child per month.
  • Meal allowance raised from ₹50 to ₹200 per meal (tax-free).
  • Employer gift exemption raised from ₹5,000 to ₹15,000 annually.

Compliance Changes

  • ITR-3 and ITR-4 due date extended to August 31 (from July 31).
  • All TDS provisions consolidated under a single Section 393.
  • TCS on foreign tours reduced to a flat 2%.
  • Buyback of shares taxed as capital gains (not dividend tax) from April 2026.
  • MOTOR accident compensation interest made fully tax-exempt.

Significance

This reform is India's biggest tax simplification since 1961. It reduces compliance burden, makes the new regime the default, and provides significant relief to the middle class through higher rebates and allowances.
