An unmarried taxpayer itemized deductions of $6,650 in 2013, which included $3,700 of state income tax withheld. In 2014, the taxpayer received an $800 state tax refund. According to the tax benefit rule, the taxpayer must include $550 of the refund in gross income for 2014, as the taxpayer received a $550 tax benefit in 2013 from itemizing deductions over the standard deduction amount.
