With high and rising public debt, an aging population that will place increasing demands on federal spending, and a need for new investments in public goods like infrastructure and R&D, the federal government requires more funding to sustain economic growth and opportunity. The existing array of taxes have limited revenue potential, can be inefficient, and place an excessive burden on low earners. It is therefore important to examine new potential sources of tax revenues and consider the roles they could play in our overall tax system.
To raise revenue, Antonio Weiss and Laura Kawano propose a new tax: a financial transaction tax (FTT). The tax would apply to a broad range of assets—including stocks, bonds, and derivatives—in order to raise as much revenue as possible while also preventing potential distortionary effects. Certain assets (such as U.S. government bonds and new equity issuances) would be exempted for efficiency reasons. The tax would start at 2 basis points and be phased in over four years until it reached its target level of 10 basis points. Prior to each annual adjustment, the U.S. Department of the Treasury would consult with other regulatory agencies to monitor the effects of the FTT.
