About IRS Schedule A (Form 1040)
Schedule A, Itemized Deductions, is filed with Form 1040 when you choose to itemize instead of taking the standard deduction. It groups deductible costs into sections such as medical and dental expenses, taxes you paid, interest you paid, gifts to charity, and casualty and theft losses, then carries the total to your Form 1040.
