The IRS has created a page on IRS.gov for information about Publication 584-B, at www.irs.gov/pub584b. Information about any future developments affecting Publication 584-B (such as legislation enacted after we released it) will be posted on that page.

This workbook is designed to help you figure your loss on business and income-producing property in the event of a disaster, casualty, or theft. It contains schedules to help you figure the loss to your office furniture and fixtures, information systems, motor vehicles, office supplies, buildings, and equipment. These schedules, however, are for your information only. You must complete Form 4684, Casualties and Thefts, to report your loss.
