After you have figured your adjusted gross income, you are ready to subtract the deductions used to figure taxable income. You can subtract either the standard deduction or itemized deductions. Itemized deductions are deductions for certain expenses that are listed on Schedule A (Form 1040). The ten chapters in this part discuss the standard deduction, each itemized deduction, and the limit on some of your itemized deductions if your adjusted gross income exceeds certain amounts. See chapter 22 for the factors to consider when deciding whether to subtract the standard deduction or itemized deductions. Figure 2, Finding Schedule A Information in Publication 17, below, shows you where the items found on Schedule A are discussed in this publication.
