FUNDAMENTAL TAX REFORM: A COMPARISON OF THREE OPTIONS Alan D. Viard* Revised November 5, 2015 Abstract: Three prominent tax reform options can significantly reduce the tax penalty on saving and investment while maintaining a progressive federal tax system: partially replacing the income tax system with a value added tax, fully replacing the income tax system with a Bradford X tax, or fully replacing it with a personal expenditure tax. This paper compares the options’ political viability and their implications for economic growth, progressivity, transitional wealth effects, business taxation, public and private transfer payments, financial intermediation, international transactions, and the non-business sector. The paper also outlines a hybrid option. * American Enterprise Institute, Washington, D.C., 202-419-5202,

There has been interest in moving to consumption taxation, which offers potential efficiency advantages by avoiding the individual and corporate income taxes’ penalties on saving and investment. However, any move to consumption taxation must address distributional concerns. The complete replacement of the income tax system with a retail sales tax or a value added tax (VAT) would be a troubling and politically problematic move away from tax progressivity.
