Wealth Taxation: An Overview of the Issues

Abstract

Two Democratic presidential candidates, Senator Elizabeth Warren (D-Massachusetts) and Senator Bernie Sanders (I-Vermont), have proposed annual wealth taxes. Annual wealth taxes have been adopted in a number of European countries (many of which later repealed them), but not in the United States. Although the proposed wealth tax rates appear low, they are equivalent to high-rate income taxes. Due to the pronounced concentration of wealth in the United States, a wealth tax would be highly progressive. The tax would probably reduce national saving and investment to some extent, although capital inflows would ameliorate the investment reduction. Congress would likely add exemptions for selected assets, which would be distortionary and diminish the tax’s revenue yield. The tax would face compliance and administration challenges due to undervaluation and concealment of assets and it might be ruled unconstitutional in the absence of suitable modifications. Although those challenges would probably not be insurmountable, it would be simpler and more prudent to pursue any desired increase in tax progressivity through reforms of the income tax and estate and gift taxes.
