New Income Tax Bill 2025: Old Vs New Regime Differences, Exemption Limits, and More

Introduction
The Income Tax Bill 2025 is set to revolutionize the Indian taxation system, replacing the decades-old Income Tax Act of 1961. This comprehensive tax reform introduces a new structure, revised tax slabs, and major procedural simplifications. The new tax regime aims to enhance compliance, reduce disputes, and introduce digital governance. In this article, we break down the key changes, differences between the old and new regimes, updated tax slabs, and exemptions to help taxpayers understand the impact.
Key Highlights of the Income Tax Bill 2025
- The bill consists of 536 sections and 23 chapters.
- The old “previous year” term has been replaced with “tax year”.
- Assessment year concept has been eliminated.
- Number of schedules increased from 14 to 16.
- Greater powers delegated to CBDT (Central Board of Direct Taxes).
- Emphasis on digital tax governance and streamlined compliance.
- Clarity on stock options (ESOPs) taxation to reduce disputes.
Old vs New Tax Regime: What’s Changed?
One of the most significant shifts is the elimination of the assessment year concept. Previously, tax for income earned in FY 2023-24 was paid in the assessment year 2024-25. The new system simplifies taxation by aligning tax calculations with a single tax year.
The number of sections has increased from 298 to 536, ensuring a more structured and modern approach to tax administration. Despite the increase, the overall length of the law has been reduced from 880 pages (Income Tax Act, 1961) to 622 pages.
Another critical change is the empowerment of the CBDT, which can now make procedural changes, introduce compliance frameworks, and implement digital monitoring systems without parliamentary approval. This will reduce bureaucratic delays and increase tax compliance efficiency.
