India’s Goods and Services Tax (GST), implemented on July 1, 2017, marks nine years since its introduction as one of the country’s most significant economic reforms. Envisioned as “one nation, one tax,” GST replaced a complex web of central and state indirect taxes with a unified national tax system aimed at simplifying compliance and reducing the cascading effect of taxation.
At the time of its launch, GST subsumed multiple taxes including excise duty, service tax, VAT, CST, octroi and entertainment tax, bringing businesses under a single tax framework. The reform also established the GST Council under the Constitution (101st Amendment) Act, 2016, enabling joint decision-making between the Centre and states on tax rates and policy matters.
Over the years, GST has significantly expanded India’s taxpayer base, which has grown from 6.65 million at inception to around 16 million in 2026, reflecting increased formalisation of the economy. The system has also contributed to the creation of a unified national market by removing inter-state tax barriers and streamlining the movement of goods and services across the country.
Despite initial challenges in compliance and transition, GST has evolved into a key pillar of India’s indirect tax structure. As it enters its tenth year, the reform continues to shape the country’s fiscal landscape, with ongoing efforts focused on simplifying returns, improving compliance systems and enhancing ease of doing business across sectors.
