The Government of India has introduced the Income-tax Act, 2025, a landmark reform aimed at simplifying the country’s complex tax framework. Replacing the decades-old Income-tax Act, 1961, the new law focuses on clarity, reduced litigation, and ease of compliance without introducing major policy changes.
With effect from April 1, 2026, the revamped legislation brings structural simplification, removes redundant provisions and introduces the concept of a "Tax Year", aligning India with global tax practices.
Why Was the New Income-tax Act Introduced?
Over the years, the Income-tax Act, 1961 became increasingly complex due to frequent amendments, expansions, and legal jargon. Originally containing 298 sections, it grew to 819 sections, making it difficult for taxpayers and professionals to navigate.
To address these challenges, the government initiated a comprehensive review in Budget 2024, aiming to:
- Simplify legal language
- Reduce compliance burden
- Minimize disputes and litigation
- Improve tax certainty
