State-Wise GST Collections: Assam Records Strong Growth
The state-wise data presents a mixed picture, with several states recording double-digit growth while some reported a decline.

The number of GSTINs stood at 96,85,707 in the latest period, compared with 73,16,526 in the corresponding earlier period reflected in the report. The data indicates continued expansion of the registered taxpayer base across several states.
Uttar Pradesh, Maharashtra, Gujarat, Karnataka and Tamil Nadu are among the states with a particularly large number of GST registrations.
What the August GST Numbers Indicate
The August 2026 GST figures point towards continued strength in India's indirect tax collections. Gross revenue grew at a faster pace than net revenue, largely because refunds increased significantly during the month.
The 14.8% growth in gross GST collections, combined with an 11% cumulative growth during April-August, indicates that GST revenue remains on a firm growth trajectory. At the same time, the sharp increase in refunds highlights the importance of looking at both gross and net collections when assessing GST revenue performance.
The government has clarified that the figures are provisional, and the actual numbers may vary slightly after finalisation.
