8 Years of GST: India’s Tax Reform Journey and the Road Ahead

As India marks the 8th anniversary of the Goods and Services Tax (GST) on July 1, 2025, the landmark reform stands as one of the most ambitious transformations in the country’s economic history. Introduced in 2017, GST replaced a complex web of central and state taxes with a unified, destination-based tax system aimed at fostering a common national market. Over the past eight years, GST has evolved significantly. From its rocky beginnings—with technical glitches, compliance challenges, and uncertainty among businesses—the system has matured into a more stable and integral part of India’s fiscal framework. It has streamlined the indirect tax structure by subsuming multiple levies like VAT, excise duty, service tax, and octroi, thereby reducing the cascading effect of taxes and improving transparency.

One of the most notable achievements of GST has been its impact on revenue collection. In FY 2024–25, GST collections touched a record ₹22.08 lakh crore, reflecting a 9.4% year-on-year growth. Monthly average collections have also consistently crossed ₹1.5 lakh crore, indicating improved compliance and economic resilience. The GST Network (GSTN) has introduced automation, real-time data matching, and AI tools to plug revenue leakages and identify tax evasion more efficiently.

Yet, the journey has not been without its challenges. Small businesses and MSMEs have faced difficulties with frequent rule changes, classification disputes, and technological barriers. The multiplicity of tax slabs—ranging from 0% to 28%—has often added complexity rather than reducing it. Recognizing these issues, the government is now considering further rationalisation of the GST rate structure, including the possible abolition of the 12% slab, especially on commonly used goods, to make the system more consumer-friendly and easier to administer.

The GST Council has played a pivotal role in shaping the reform, balancing the interests of the Centre and States. With increased digitisation, the future of GST looks more streamlined and predictable. New rules introduced in July 2025—such as the three-year time limit for filing returns and the hard-locking of GSTR-3B—reflect a push toward greater accountability and timely compliance.

As GST completes eight years, it is clear that while the reform has achieved much in terms of simplification and revenue enhancement, there is still room for improvement. With continued collaboration between the government, businesses, and tax professionals, GST has the potential to become a truly world-class tax system that supports growth, formalisation, and ease of doing business in India.
