Use Schedule A (Form 1040) to figure your itemized deductions. In most cases, your federal income tax will be less if you take the larger of your itemized deductions or your standard deduction.
If you itemize, you can deduct a part of your medical and dental expenses and unreimbursed employee business expenses, and amounts you paid for certain taxes, interest, contributions, and miscellaneous expenses. You can also deduct certain casualty and theft losses.
If you and your spouse paid expenses jointly and are filing separate returns for 2008, see Pub. 504 to figure the portion of joint expenses that you can claim as itemized deductions.
Do not include on Schedule A items deducted elsewhere, such as on Form 1040 or Schedule C, C-EZ, E, or F.
Certain cash contributions you made for relief efforts in a Midwestern disaster area are not subject to the overall limitation on itemized deductions or the 50% adjusted gross income limitation. See Pub. 526 for more details.taxmap/instr/i1040sa-000.htm#TXMP5651a0e7
