The seven federal income tax brackets made it through 2015 without any congressional changes. However, the earnings amounts that fall into each tax rate were adjusted, as usual, for inflation. This means you can make a bit more money without facing a substantial increase in your tax bill. For the 2015 tax year, the seven individual income tax rates and applicable earnings are shown in the table below.
