Tax Buoyancy
Concept and India's Performance
Tax buoyancy measures how responsive tax revenue is to changes in GDP — a buoyancy of greater than 1.0 means taxes grow faster than GDP. India's GST has shown improving buoyancy over time as compliance improves (via e-invoicing, e-way bills, GSTN analytics). The FY26 GST growth of 8.3% against a nominal GDP growth of approximately 9–10% indicates broadly neutral buoyancy. Direct tax collections have separately seen record growth. Together, overall tax revenue buoyancy above 1.0 has been a feature of Indian fiscal performance post-FY22.
- Tax-to-GDP ratio: India's total taxes ~18% of GDP (FY26 estimated); global average for emerging markets ~15–20%
- GST compliance: monthly filer base reached ~14 million registered taxpayers in FY26
- E-invoicing mandate (above ₹5 crore turnover): covers ~90%+ of B2B transactions by value
- GSTN (GST Network): IT backbone processing ~600–700 million invoices monthly
- Health and Security Cess (2026): new cess introduced in Union Budget 2026 on specific goods to fund health infrastructure and border security
