What were the 2013 Federal tax rates?

The federal tax rates for 2013 vary depending on a taxpayers income, but ranged between 10 percent to 39.6 percent for the top bracket, as stated on the tax table provided by Efile, the authorized IRS electronic tax filing site. The taxes are tiered, so a taxpayer may end up having to pay multiple rates on different portions of their income.

The amount of money that someone can make under a given tax rate varies on how the taxpayer files, according to Efile. Single, married filing separately, married filing jointly and head of household all have different limits before the tax percentages on their income changes with head of household having the highest limit.
