Below are all of the tax rates, along side their respective income levels.  I found the data at Money Chimp, so you can review it for yourself.  Remember, all these tax rates are on NET, not GROSS income.  For those that do not know the difference, Gross is what you earn and Net is what you actually bring home, after all deductions.
