Federal income tax is a tax imposed by the U.S. federal government on business income. The Internal Revenue Service (IRS) administers federal income tax.

Self-employment tax generally applies to individuals who work for themselves rather than as employees. It depends on how the business is organized and how the owner receives business income. It helps fund Social Security and Medicare programs.
