Tax Buoyancy
Tax buoyancy measures how responsive tax revenue is to changes in economic growth, showing whether collections rise faster or slower than GDP.
A tax buoyancy above one means tax revenue grows faster than nominal GDP — a sign of an efficient, widening tax base and improving compliance. Buoyancy below one suggests collections are lagging growth, perhaps due to evasion, exemptions or a narrow base.
Indian Budgets rely on buoyancy assumptions to project receipts; over-optimistic buoyancy can lead to revenue shortfalls. Reforms such as GST, faceless assessment and digitisation are intended to lift buoyancy by formalising the economy and improving compliance.
