Expiring sales tax deductions could cost taxpayers big in these states

In Washington state, which has a high sales tax but no income tax, nearly three in ten filers claim a sales tax deduction. The average filer claims more than $600 in deductions. More than 20 percent of all tax filers in Nevada and Texas claim sales tax deductions; so do more than 15 percent of filers in Florida, Tennessee, Wyoming and South Dakota. All seven of those states have no state income tax.
