The Goods and Services Tax (GST) is an indirect tax introduced in India on 1 July 2017, implemented nationwide to replace multiple cascading taxes levied by the central and state governments. Enacted through the Constitution (One Hundred and First Amendment) Act, 2017, GST initially operated under a multi-rate framework with tax slabs of 0%, 5%, 12%, 18%, and 28%. Major GST reforms implemented on 22nd September 2025, commonly referred to as GST 2.0, further streamlined the system by consolidating rates into a three-tier structure of 5%, 18%, and 40%, aiming to simplify compliance, enhance tax efficiency, support micro, small, and medium enterprises (MSMEs), and improve consumer affordability. The 2025 reforms marked a significant milestone in India’s indirect taxation system by rationalizing tax rates and stimulating domestic consumption. Reductions in GST rates on essential goods and selected consumer durables lowered retail prices, increasing disposable income and purchasing power, which in turn led to higher spending on essential items, greater demand for consumer durables, and a gradual shift toward premium and value-added products. The reforms also influenced the timing of purchases, as consumers postponed high-value expenditures in anticipation of price reductions, followed by a post-reform surge in demand. Enhanced tax transparency and the reduction of cascading effects strengthened consumer confidence, encouraging participation in organised retail, formal markets, and e-commerce platforms, while promoting digital transactions and overall market efficiency. Overall, the 2025 GST reforms positively impacted consumer purchasing behavior across income groups, particularly among middle and lower-income households by boosting consumption, fostering market formalization, and supporting long-term changes in spending patterns within the Indian economy.
