Revised: October 2017

Publication 584-B - Introductory Material

What’s New

Disaster tax relief was enacted for those impacted by Hurricane Harvey, Irma, or Maria, including provisions that modified the calculation of casualty and theft losses of personal-use property. See Pub. 976, Disaster Relief, for more information about these and other disaster tax relief provisions that may not be covered in this publication.


Future developments. For the latest information about developments related to Pub. 584-B, such as legislation enacted after it was published, go to

Photographs of missing children. The Internal Revenue Service is a proud partner with the National Center for Missing & Exploited Children® (NCMEC). Photographs of missing children selected by the Center may appear in this publication on pages that would otherwise be blank. You can help bring these children home by looking at the photographs and calling 1-800-THE-LOST (1-800-843-5678) if you recognize a child.


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.

Adjusted basis.

Adjusted basis usually means original cost plus improvements, minus depreciation allowed or allowable (including any section 179 expense deduction), amortization, depletion, etc. If you didn’t acquire the property by purchasing it, your basis is determined as discussed in Pub. 551. If you inherited the property from someone who died in 2010 and the executor of the decedent's estate made the election to file Form 8939, refer to the information provided by the executor.

Fair market value.

Fair market value is the price for which you could sell your property to a willing buyer, when neither of you has to sell or buy and both of you know all the relevant facts. When filling out Schedules 1 through 6, you need to know the fair market value of the property immediately before and immediately after the disaster or casualty.

Deduction limits.

If your casualty or theft loss involved a home you used for business or rented out, your deductible loss may be limited. See the Instructions for Form 4684, Section B. If the casualty or theft loss involved property used in a passive activity, see Form 8582 and its instructions.

The casualty and theft loss deduction for employee property, when added to your job expenses and most other miscellaneous itemized deductions on Schedule A (Form 1040), must be reduced by 2% of your adjusted gross income. Employee property is property used in performing services as an employee.
