When the Goods and Services Tax (GST) was rolled out on 1 July 2017, it marked one of the most ambitious economic reforms in independent India’s history. Replacing a maze of central and state levies, GST aimed to simplify the country’s indirect tax system and unify the nation into a seamless common market. Eight years on, GST has not only redefined how businesses transact across states but also laid the foundation for a more transparent, technology-driven tax ecosystem. As the economy continues to evolve, this milestone offers a timely opportunity to assess the journey so far—measuring its gains, acknowledging the challenges, and charting the path towards a more efficient and inclusive tax regime.
