The Income Tax Bill 2025 is set to replace the 60-year-old Income Tax Act, 1961. The bill introduces a new tax year system, removing the "assessment year" concept. The new tax slabs offer zero tax on income up to ₹12 lakh, with rates revised for higher brackets. The CBDT gains more authority to simplify tax administration and reduce bureaucracy. The bill also aims to clarify ESOP taxation and reduce litigation. With 536 sections, it promises a more efficient, digital, and structured tax system for India.
