What would taxes be on 30,000 from a 1099 after all deductions

[GilbertC]

For self-employment income there is a FICA tax of 15.3% (the 12.4% of Social Security tax plus the 2.9% of Medicare tax). There is also a Medicare surtax that applies to higher income taxpayers. So if the surtax does not apply to you $4,590.
