Hauser's law (original) (raw)

Hauser's law is the empirical observation that, in the United States, federal tax revenues since World War II have always been approximately equal to 19.5% of GDP, regardless of wide fluctuations in the marginal tax rate. Historically, since the end of World War II, federal tax receipts as a percentage of gross domestic product averaged 17.9%, with a range from 14.4% to 20.9% between 1946 and 2007.
