For example, unreimbursed medical expenses are deductible if they exceed 7.5% of Adjusted Gross Income (AGI) in a tax year, and casualty and theft losses must exceed 10% of AGI before they are deductible. In order to deduct miscellaneous expenses, they must total at least 2% of adjusted gross income.
