Definition and Meaning of 2025 Schedule A (Form 1040) Itemized Deductions

The 2025 Schedule A (Form 1040) Itemized Deductions is an IRS form used by taxpayers in the United States to report specific deductions that can reduce their taxable income. This form allows you to itemize particular expenses instead of taking the standard deduction, potentially lowering your overall tax bill if the total itemized deductions exceed the standard deduction amount. Common expenditures included in this form are medical expenses, mortgage interest, state taxes, and charitable contributions.
