Mileage
You can claim deductible business auto/truck expenses for driving from one client to the next in one of two ways.
Cell phone
The costs of a cell phone may be a business expense, but only the additional costs in using a cell phone for business are deductible. The Tax Court has several interesting cases on this. In one case, the taxpayer paid a flat rate on a phone used for business and personal calls. The court held that as he paid a flat rate for his personal phone and incurred no additional charges for business use, he has no deduction. (Ritchie, TC Summary Opinion 2005-181).
For an employee, if deductible, they would be entered as a miscellaneous itemized deduction for employee business expenses.
Example from Ritchie: "Petitioner’s cell phone was a personal phone that he also used for business calls. Petitioner testified that he paid a flat rate, regardless of phone usage. Therefore, aside from the personal expense of the phone, which is rendered nondeductible under § 262, he incurred no additional charge for business use."
Scrubs
Certain types of costs are entered as employee business expenses. These include work clothes and uniforms if required and not suitable for everyday use. The IRS criteria for uniforms and work clothes is in Publication 529.
