India’s Goods and Services Tax (GST) collections serve as a key high-frequency indicator of economic health. Crossing the ₹2 lakh crore monthly collection mark is considered a milestone, indicating strong economic activity. In July 2026, the gross collection reached ₹2.11 lakh crore, which is the second time it crossed this mark in FY27, indicating robust nominal transaction volumes.

In India’s GST framework, Integrated GST (IGST) is levied on all imports and inter-state transactions. While import IGST goes to the Center first before being settled with consuming states, a high growth in import IGST (26.9%) compared to a low growth in domestic GST (4.5%) indicates that the government’s tax collections are highly dependent on imports. Tax buoyancy indicates how tax collection responds to economic growth; here, the buoyancy is trade-led, meaning it is driven by import values rather than domestic economic activity.

When a currency like the Indian Rupee depreciates against the US Dollar, it takes more rupees to buy the same amount of dollar-priced goods. This makes imported commodities (such as crude oil, electronics, and chemicals) more expensive in rupee terms. Since these items account for roughly 50% of India’s import basket, a 10%-12% drop in the rupee value leads to a higher import bill. Since GST on imports (IGST) is calculated as a percentage of the rupee value of imports, a higher rupee cost automatically inflates the IGST collected, even if the actual quantity of goods imported did not increase.

India is one of the largest consumers of gold globally, importing most of its supply as bullion (refined gold bars). In May 2026, the government increased the import duty on gold to 15% to check foreign exchange outflows. This duty hike resulted in official bullion imports dropping by 22% in the second quarter of 2026, pushing physical supply to a six-year low of 120 tonnes. However, because of high gold prices domestically and the import tax itself, the total value of import tax (IGST) collected on gold remained high, artificially boosting the government’s overall tax collections.

GST is an ‘ad valorem’ tax, meaning it is charged as a percentage of the value of the transaction. Because of this, when wholesale inflation (WPI) is high (especially manufacturing inflation at 7.18%), the nominal price of goods increases. Consequently, the GST collected on those goods also increases, even if the actual volume or quantity of goods produced and sold has declined. This explains why domestic GST revenues grew by 4.5% despite manufacturing activity dropping to a five-year low, as measured by the HSBC Manufacturing PMI, which tracks business activity by surveying purchasing managers.

The services sector contributes over 50% to India’s GDP but is highly concentrated in a few states like Maharashtra, Karnataka, Tamil Nadu, and Delhi, which house the country’s major financial, IT, and corporate hubs. Consequently, any growth or buoyancy in service-related GST is not uniform across India but remains concentrated in these few high-income regions, leaving other states with little tax benefit from the services boom.

Under India’s GST framework, tax collected on inter-state trade and imports (IGST) is pooled by the Center and then distributed (‘settled’) to the states where the goods or services were consumed. States with large manufacturing bases (like Gujarat) or strong service hubs (like Karnataka) generate high tax revenues. In contrast, states with large unorganised sectors (such as Bihar or Uttar Pradesh) struggle to generate tax revenues because informal businesses operate outside the GST net. These states become heavily dependent on ‘central transfers’ and ‘Finance Commission devolution’, the periodic sharing of central tax revenues mandated by Article 280 of the Constitution to address fiscal imbalances among states.

India launched the GST in 2017 (GST 1.0) to unify multiple indirect taxes under ‘One Nation, One Tax’. The subsequent phase (GST 2.0) focused on rate rationalization, reducing the tax slabs in 2025. ‘GST 3.0’ refers to the next generation of reforms, which aims to leverage AI/ML for seamless compliance, bring excluded sectors like petroleum and alcohol into the GST net, and address federal imbalances by ensuring that tax collections are geographically inclusive and benefit all states equitably.

Input Tax Credit (ITC) is the core feature of GST that prevents ‘tax cascading’ (tax on tax) by letting businesses deduct tax paid on inputs (purchases) from tax due on output (sales). However, ITC has become the biggest source of legal disputes (litigation) in the GST ecosystem. Discrepancies between invoices uploaded by suppliers and buyers led to tax notices, blocking of credits, and lawsuits. While the government has improved the GST IT portal and speeded up domestic refunds, these complex legal disputes and ‘faultlines’ remain unresolved, locking up business working capital as ‘credit balances’.

The ‘Make in India’ initiative was launched in 2014 with the goal of increasing manufacturing’s share of GDP to 25% and creating 100 million jobs. However, India’s manufacturing sector remains heavily dependent on imported inputs (such as electronic components, active pharmaceutical ingredients, and machinery). When these raw materials are imported, they pay IGST, which inflates the overall GST metrics. This means that high tax collections are driven by external imports rather than value added inside the country, highlighting a gap between the ‘Make in India’ goals and real domestic production.
