RAS question
Tax buoyancy is defined as:
Correct answer: (D) Responsiveness of tax revenue to changes in GDP including discretionary measures.
Tax buoyancy is the responsiveness of tax revenue to changes in GDP, including the effect of discretionary changes in tax policy.
Explanation
Tax buoyancy measures how strongly tax revenue moves when GDP changes. In exam terms, it is calculated as the percentage change in tax revenue divided by the percentage change in GDP. A buoyancy value above 1 means tax revenue is rising faster than GDP. The key distinction is that buoyancy is not a clean measure of the tax system's automatic response alone: it includes discretionary tax-policy measures such as rate changes or new taxes. RBI's Annual Report uses the same idea in its tax buoyancy table, defining it as responsiveness of tax revenue to changes in nominal GDP and to discretionary changes in tax policies. That is why option D is the precise definition.
Why the other options are wrong
- (A) Tax refunds are amounts returned to taxpayers; they do not measure how tax revenue responds to GDP growth.
- (B) The direct-to-indirect tax ratio describes the composition of tax revenue, not its responsiveness to changes in GDP.
- (C) Tax revenue collected per capita is an average revenue measure, whereas buoyancy compares percentage changes in revenue with percentage changes in GDP.
Concept
This tests public finance terminology under Indian Economy, especially revenue performance indicators used in Budget analysis. It recurs in RAS because tax buoyancy helps interpret fiscal capacity, growth-linked revenues and the effect of tax-policy changes.
