Brief History of IRS. Origin. The roots of IRS go back to the Civil War when President Lincoln and Congress, in 1862, created the position of commissioner of Internal Revenue and enacted an income tax to pay war expenses. The income tax was repealed 10 years later.
However, in 1894 Congress enacted a flat rate Federal income tax, which was ruled unconstitutional the following year by the U.S. Supreme Court because it was a direct tax not apportioned according to the population of each state.
