Tax Performance and Taxable Capacity: Analysis for Selected States of India
Abstract In a federal form of government structure, the state-level governments generally receive supplementary budgetary resources from the central/federal government as support for the formers’ public expenditure activities. Such devolution of funds from the centre to the states takes the form of share of the revenue raised by central taxes and grants-in-aid. It is felt that such resource transfers should be made according to a policy based on the criteria of equity and efficiency. Formally, these criteria are defined with reference to individual state’s tax revenue collection relative to its taxable capacity. Formulation of a concrete transfer policy, however, crucially requires measures of individual state’s taxable capacity. Given an appropriate definition of a state’s taxable capacity, measurement of taxable capacity of states involves both conceptual and econometric issues. This paper proposes an econometric approach to the measurement of taxable capacity, which is similar to estimating a frontier production function using panel data. To illustrate the proposed method, it is applied to the panel data on annual state tax revenue and related variables of some selected Indian states for the period 1986-87 to 1996-97 and the relative taxable capacity and tax efforts of the states are compared.
