Final answer:
A taxpayer who claims the standard deduction will not be affected by the 2% floor on unreimbursed employee expenses.
Step-by-step explanation:
A taxpayer who claims the standard deduction will not be affected by the 2% floor on unreimbursed employee expenses. This is because the standard deduction is a fixed amount that reduces taxable income, while the 2% floor applies to itemized deductions, including unreimbursed employee expenses. If the taxpayer chooses to itemize deductions instead of taking the standard deduction, they would be subject to the 2% floor on unreimbursed employee expenses.
