The 2015 tax chart is available online, as the Internal Revenue Service published updated tax bracket information on Oct. 30, 2014. Details of the tax rate charts appear in Revenue Procedure 2014-61 located through the Internal Revenue Service website.
The published information contains the 2015 information for standard deductions, itemized deduction limitations, and tax brackets for all filing statuses. The IRS also published Earned Income Credit tables as well as gift tax limitations. The IRS adjusted more than 40 tax provisions from 2014 due to inflation. The methods the IRS uses to adjust tax provisions from year to year are part of the legal code. These tax provisions utilize the Consumer Price Index, which measures the changes in relative consumer prices.
