The Goods and Services Tax (GST) was introduced in India in July 2017 with the aim of simplifying the indirect tax structure, improving tax compliance, and creating a unified national market. Since its implementation, GST has become an important source of government revenue. This study examines the trend and growth pattern of GST revenue collections and explores how GST revenue is related to economic growth in India. The analysis is based on secondary data obtained from official government sources, covering the period from July 2017 to January 2026. Various statistical techniques, including trend analysis, moving averages, seasonality analysis, Year-on-Year (YoY) growth, Compound Annual Growth Rate (CAGR), tax buoyancy, correlation, and regression analysis, are used to understand the behaviour of GST revenue and its relationship with Gross Domestic Product (GDP). The results show a steady increase in GST collections over time, with a temporary decline during the COVID-19 pandemic followed by a strong recovery. The findings also reveal a strong positive relationship between GST revenue and GDP, suggesting that GST collections tend to rise as economic activity expands and therefore play an important role in supporting fiscal stability.
