Deducting Business Use of Car at a Glance

Español

If you use your car in your job or business and you use it only for that purpose, you may be able to deduct its entire cost of operation. However, if you use the car for both business and personal purposes, you may deduct only the cost of its business use and you must keep records to support your claim.

Your unreimbursed employee expenses are subject to the 2 percent of adjusted gross income floor on Schedule A.
