Irwin Allen Schiff (/ʃɪf/; February 23, 1928 – October 16, 2015) was an American libertarian and tax resistance advocate[1] known for writing and promoting literature in which he argued that the way in which the income tax in the United States is enforced upon individuals, as a tax on one's time or wages, is illegal and unconstitutional. Judges in several civil and criminal cases ruled in favor of the federal government and against Schiff. As a result of these judicial rulings Schiff was in a hospital prison serving a sentence of 162 months (13.5 years) at the time of his death.
Schiff was the father of businessman and former United States Senate candidate Peter Schiff.[2]
