Capital levy

A capital levy is a tax on capital rather than income, collected once, rather than repeatedly (regular collection would make it a wealth tax). For example, a capital levy of 30% will see an individual or business with a net worth of $100,000 pay a one-off sum of $30,000, regardless of income. Capital levies are considered difficult for a government to implement.

Some economists argue that capital levies are a disincentive to savings and investment, and cause capital flight, but others argue that in theory this need not be the case. The latter view was popular in the World Wars; in the 2010s, it has also gained some acceptance as more heavily indebted nations struggle to raise revenues.
