The reason we need the flat tax: I started to understand below as I read but why in Hell so complicated? @laughingduck
[h=3]Self-employed people[/h] A tax similar to the FICA tax is imposed on the earnings of
self-employed individuals, such as
independent contractors and members of a
partnership. This tax is imposed not by the Federal Insurance Contributions Act but instead by the
Self-Employment Contributions Act of 1954, which is codified as Chapter 2 of Subtitle A of the Internal Revenue Code,
26 U.S.C. § 1401 through
26 U.S.C. § 1403 (the "SE Tax Act"). Under the SE Tax Act, self-employed people are responsible for the entire percentage of 15.3% (= 12.4% [Soc. Sec.] + 2.9% [Medicare]); however, the 15.3% multiplier is applied to 92.35% of the business's
net earnings from self-employment, rather than 100% of the gross earnings; the difference, 7.65%, is half of the 15.3%, and makes the calculation fair in comparison to that of regular (non-self-employed) employees. It does this by adjusting for the fact that employees' 7.65% share of their SE tax is multiplied against a number (their gross income) that does not include the putative "employer's half" of the self-employment tax. In other words, it makes the calculation fair because employees don't get taxed on their employers' contribution of the second half of FICA, therefore self-employed people shouldn't get taxed on the second half of the self-employment tax. Similarly, self-employed people also deduct half of their self-employment tax (schedule SE) from their gross income on the way to arriving at their adjusted gross income (AGI). This levels the amount paid by self-employed persons in comparison to regular employees, who don't pay general income tax on their employers' contribution of the second half of FICA, just as they didn't pay FICA tax on it either.[SUP]

These calculations are made on Schedule SE: Self-Employment Tax, although that is not readily apparent to novice self-employed taxpayers, owing to the schedule's rather opaque name, which makes it sound like it is part of the general federal income tax. Some taxpayers have complained that Schedule SE's title should be changed to something such as "Self-Employment FICA Tax", so that its separateness from the general income tax is apparent,[SUP]
[12][/SUP] perhaps not realizing that the SE tax is not imposed by the Federal Insurance Contributions Act (FICA) at all, and that neither SE taxes nor FICA taxes are "income taxes" imposed under Chapter 1 of the Internal Revenue Code.
