GST Drives Faster State Revenue Growth Than Economy
The Goods and Services Tax, or GST, was introduced in India in 2017.
Since then, the money that state governments collect from taxes has grown faster than the overall economy.
Between 2018 and 2026, state tax collections grew about 9% each year, reaching ₹12.9 trillion.
Before GST, tax growth was only about 6.8% per year.
More people and businesses have started paying taxes—now 16.5 million are registered.
The state of Manipur has seen the biggest jump in tax revenue compared to its economy, while Maharashtra and Karnataka still bring in the most money overall.
This shows that GST has helped states collect more money in a shorter time.
GST has increased state revenue faster than economic growth since 2018.
SGST collections grew 9% CAGR to ₹12.9 trillion between FY18 and FY26.
Pre‑GST tax growth was 6.8% CAGR to ₹3.7 trillion (FY13‑17).
Registered taxpayers rose from 6.7 million to 16.5 million by May 2026.
Manipur had highest post‑GST tax buoyancy (10.74), with Maharashtra and Karnataka leading overall collections.
