Washington State Taxpayers May Deduct Sales Tax in 2014

Washington State residents may deduct state and local general-sales tax on their federal income returns for tax year 2014. The sales tax deduction was extended again in legislation H.B. 5771 (section 105) signed by President Obama on December 19, 2014.

The deduction is available to taxpayers that itemize deductions, not those who take the standard deduction. The deduction is based on adjusted gross income and number of exemptions claimed. Taxpayers who keep all their receipts can deduct actual sales tax and use tax paid. For taxpayers who didn't keep receipts, the IRS has an online Sales Tax Deduction Calculator to determine the amount of optional general sales tax to claim, or taxpayers can use the Optional State Sales Tax Tables.
