A wealth taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. would not be good for the U.S. economy.

In his book, Capital in the 21st Century, Thomas Piketty suggests a wealth taxA wealth tax is imposed on an individual’s net wealth, or the market value of their total owned assets minus liabilities. A wealth tax can be narrowly or widely defined, and depending on the definition of wealth, the base for a wealth tax can vary. to fight income inequality. In a recent report, we used our Taxes and Growth model to evaluate the impact of such a tax on the U.S. economy.

Piketty suggests a couple variations on a wealth tax with different rates starting a various income levels. One suggestion would create a 1 percent tax on net wealth between 1 and 5 million euros ($1.3 to $6.5 million) and a 2 percent tax on income over 5 million euros ($6.5 million). He also mentions a tax on “modest to average wealth” with a 0.5 percent tax rate on net wealth between 200,000 and 1 million euros ($260,000 to $1.3 million).

Our model estimates that this tax would have a significant negative impact on the economy.

The Piketty wealth tax would shrink the economy by close to $1 trillion in total size (down 6.1 percent), decrease wages by 5.2 percent and total investment would drop by over 16 percent. Additionally, it would eliminate 1.1 million jobs.

Overall, the tax would reduce after-tax incomeAfter-tax income is the net amount of income available to invest, save, or consume after federal, state, and withholding taxes have been applied—your disposable income. Companies and, to a lesser extent, individuals, make economic decisions in light of how they can best maximize after-tax income. by 9.2 percent and, while the top 1 percent would see their incomes drop 13.2 percent, the bottom 20 percent would also see they income drop 7.3 percent.

In the end, Piketty’s wealth tax—in pursuit of reducing income inequality—would make everyone worse off due to decreased economic activity.

In a previous paper we evaluated the effect of Piketty’s 80 percent tax rate on wage and investment income and found that it would shrink the economy by nearly $3 trillion.
