The Federal Income Tax is a marginal income tax collected by the Internal Revenue Service (IRS) on most types of personal and business income. The federal income tax consists of six marginal tax brackets, ranging from a minimum of 10% to a maximum of 39.6%.
The individual income tax has been the largest single source of federal revenue since 1950, amounting to 47.3 percent of the total and 8.4 percent of gross domestic product (GDP) in 2016. In recent years, individual income tax revenue has climbed as high as 9.9 percent of GDP (in 2000) at the peak of the 1990s economic boom and dropped as low as 6.1 percent (in 2010) following the 2007-2009 Great Recession.
