These income tax brackets dictate how much federal income tax you will pay when you file your tax returns this April. Remember, however, that these are marginal tax rates. That means that the highest rate applies only to money you earn above and beyond the upper limit of the lower rate.

An example of marginal tax rates work: If you are a single filer and earned $40,000 in 2013, you will pay 10 percent on the first $8,925, 15 percent on the next $27,955 and 25 percent on the remaining $3,750.

These rates have changed since 2012 as a result of legislation to end the fiscal cliff at the end of last year.
