Overview of GST Growth in India

The taxpayer base for the Goods and Services Tax (GST) in India has seen remarkable growth, escalating from 6.65 million in 2017 to 16.5 million by May 2026. This surge has been accompanied by a substantial increase in revenue collections. In the fiscal year 2017-18, gross GST collections jumped from approximately ₹7.4 lakh crore to nearly ₹22.27 lakh crore by 2025-26, according to official statistics. Over the past five years, collections have also risen from around ₹13.76 lakh crore in 2021-22. The upward trend has persisted into 2026-27, with GST collections hitting about ₹4.37 lakh crore during the months of April and May 2026.

In June 2026, India's gross GST collections experienced a year-on-year increase of 13.9%, reaching ₹1.95 lakh crore, largely fueled by a significant rise in revenue from imports. To mark nine years of GST implementation, Deloitte has published the 'India’s GST@9' survey, highlighting its transformation into a strong digital ecosystem supported by robust industry confidence. The forthcoming phase, referred to as GST 2.0, aims to advance beyond mere digitalization towards a more intelligent, predictive, and integrated framework. This evolution will focus on AI-driven compliance, data-led dispute resolution, and an enhanced, unified experience for taxpayers.
