This research examines the comparative aspects and implications of India's old and new tax regimes with focus on the recent reform i.e. New Income Tax Bill 2025. The New Income Tax Bill 2025 marks a significant change in India's taxation system. This study aims to compare the key features of the old and new tax regimes, evaluate the changes proposed in the 2025 bill, and assess public awareness and satisfaction with the current tax system. A mixed method approach was employed, combining a review of key tax provisions and a primary survey conducted through a structured questionnaire. Information was gathered from various respondents which contain different types of professions. The study concludes that although the government's efforts to simplify taxation are commendable, greater charity and targeted outreach are essential to enhance taxpayer satisfaction and compliance, and effective communication and education are essential to ensure wider acceptance and informed decision-making among taxpayers.
