If you've already paid certain taxes you may be able to claim them as itemized deductions. The three types of taxes that are good for a write-off include: state, local and foreign income taxes you paid in 2002, real estate taxes and personal property taxes you may have paid for a car or boat. You'll claim the itemized deductions on Schedule A that accompanies the federal Form 1040. For more information, see Publication 17, which you can download from the IRS web site (www.irs.gov).
