India’s Goods and Services Tax completes nine years, with monthly revenues averaging ₹1.85 trillion in FY26. The government is shifting focus to AI and data integration to further simplify compliance. While the taxpayer base has grown to 16 million, the inclusion of petroleum products under the tax regime remains a key pending reform for investors to track.
What Happened
India has marked nine years of the Goods and Services Tax (GST) system, which launched on July 1, 2017. As the country enters the tenth year of this tax regime, the government is shifting its strategy from simple adoption to technological efficiency. The administration is now prioritizing the integration of GST, income tax, and customs databases using artificial intelligence and data analytics. This move is designed to lower compliance burdens, particularly for micro, small, and medium enterprises (MSMEs), and to create a more transparent tax environment by reducing manual intervention.
Revenue And Taxpayer Growth
The financial impact of GST over the last nine years has been significant. At its launch, the registered taxpayer base was 6.65 million. By mid-2026, this number has risen to approximately 16 million, indicating a rapid formalization of the Indian economy.
Revenue growth has followed a similar upward trend. In the inaugural year of 2017-18, the monthly GST revenue averaged ₹89,700 crore. By fiscal year 2026, this monthly average climbed to ₹1.85 trillion. Gross GST collections for FY26 stood at ₹22.27 trillion, showing an 8.3% increase compared to the ₹22.08 trillion collected in FY25. This steady revenue performance has provided fiscal reassurance to state governments, which were initially concerned about potential revenue losses when the tax was first introduced.
Efficiency Through Technology
The current push for AI-driven compliance is aimed at replacing older, fragmented processes. By integrating different tax databases, the government intends to improve its risk assessment capabilities. For businesses, this means the potential for faster refund processing, better data-led dispute resolution, and lower costs associated with tax filing and compliance. Industry reports suggest that most businesses have experienced neutral to positive interactions with the system, largely driven by ongoing digitization and rate rationalization.
The Petroleum Challenge
Despite the success of the unified tax framework, one significant area remains unresolved: the inclusion of petroleum products. Five major categories—crude petroleum, petrol, diesel, aviation turbine fuel (ATF), and natural gas—are still outside the GST ambit. While this has been discussed by the GST Council, there is no immediate consensus. State governments have shown reluctance to surrender their taxing power over these items, particularly aviation fuel. For investors, this exclusion means that these sectors continue to operate under a different tax structure, creating a split in the overall indirect tax landscape.
What Investors Should Track
As GST moves into this new phase, the primary monitorable is the success of AI and data integration in reducing compliance costs. Investors should track how effectively these technological changes resolve disputes and expedite refunds for companies. Additionally, any updates regarding the GST Council's stance on including petroleum products will remain a critical factor to watch, as this would impact the cost structure and tax predictability for energy, logistics, and aviation sectors.
