Uniformity Doctrine in Taxation

Overview

The uniformity doctrine is the public-finance principle, associated with Columbia economist Edwin R. A. Seligman, that a tax system achieves neutrality only when it applies uniformly across land and capital rather than singling land out for special treatment. Seligman built the argument on John Bates Clark's capital theory — which treated land as simply one form of capital — reasoning that a tax falling only on land would drive capital out of land and into other uses, distorting investment; he set out the position most fully in "Tax Exemption through Tax Capitalization: A Reply," American Economic Review 6(4), 1916, pp. 790–807, a rejoinder in his running exchange with T. S. Adams over how taxes capitalize into asset prices.[1]

Mason Gaffney's contested history The Corruption of Economics treats the uniformity doctrine as one of the doctrinal moves by which early-twentieth-century economists dissolved the classical distinction between land and capital, closing off the analytical basis for taxing land rent specifically; Gaffney further argues the doctrine's uniformity logic later informed the Tax Reform Act of 1986, which lowered rates on land income alongside labor and capital income and ended the investment tax credit.[2] This lineage claim is Gaffney's own interpretation and has not been independently replicated; see the wiki's treatment of the broader "corruption of economics" narrative for the mainstream counter-reading.
