The Economic Effects of Comprehensive Tax Reform

A number of recent proposals for fundamental tax reform would replace the current federal income tax system with a comprehensive consumption-based tax. Objectives of tax reform include stimulating economic activity and promoting a more efficient allocation of resources. Many common features of recent proposals could achieve those results-for example, a broader tax base, more uniform rates, and a tax on consumption rather than income. This Congressional Budget Office CBO study analyzes the major economic effects of several tax reform plans and finds that much uncertainty surrounds the likelihood and magnitude of the economic gains from tax reform. The study focuses on the effects on saving and investment, output, and the allocation of resources within the economy, as well as the ultimate impacts of those changes on social well-being. The study was prepared at the request of Senators Pete Domenici, Robert Bennett, Joseph Biden, and Robert Kerrey and former Senator Sam Nunn.
