India’s upcoming Index of Services Production (ISP) will measure formal services sector output using Goods and Services Tax (GST) data, administrative data, and surveys.
The index will be the first attempt to periodically quantify India’s formal services sector production.
GST data will be the primary source, while the Annual Survey of Incorporated Services Sector Enterprises (ASISSE) and administrative data will support sectors without GST coverage.
Administrative data sources include the Reserve Bank of India (RBI), Railway Board, Directorate General of Civil Aviation (DGCA), and Insurance Regulatory and Development Authority of India (IRDAI).
The first release of the ISP is scheduled for July 29, 2026, and it will cover only the formal services sector.
