2011 Federal Income Tax Brackets and Marginal Rates The Income tax rate (whether it's joint or single) runs from the low at 10% (which is a farce, since people that low will eventually pay nothing) to 35% at the highest level of over $379,150! However you also have state income tax. Place like CA (10%), HI (11%), NJ (9%), NY (9%), OR (11%) and VT (9%) are 9-11%! That is pretty high! In these states raising federal income taxes puts people close to the 50% tipping point! I say when the majority of one's money goes to taxes then that is immoral!
