As of the tax year 2014, the U.S. Internal Revenue Service's optional state sales tax table includes current sales tax percentage rates for each state. The table also shows the amount of estimated state sales tax a taxpayer may deduct based on income and number of exemptions claimed, according to the IRS website.
Taxpayers can find the optional sales tax table in the Instructions for Schedule A (Form 1040) booklet. The table is available for taxpayers who use IRS Form 1040 to file personal income taxes. The tax table is one of two alternatives available to taxpayers who need to estimate the amount of state sales tax to deduct on Schedule A. Alternatively, taxpayers may use the IRS sales tax deduction calculator.
The IRS divides the optional sales tax table into sections by state and lists the states alphabetically. The income section of the tax tables break down into 19 categories, beginning with $0 to $20,000 and ending with $300,000 or more. The table displays the income categories down the left side of each state tax table. The exemptions section of the state tax table read from left to right across the top of each table, and the IRS breaks down exemptions into six categories ranging from one to over five.
