<prompt> Human: I recently got a new job, to make things quick I work wherever Im needed between two buildings. Sometimes Ill be in one building all day, other times Ill be back and forth between the buildings 5 or 6 times. The buildings are close, about 2.5 miles apart by road but really only half a mile or so in a straight line. My question is, am I allowed to write these miles off on my taxes? If so, what kind of paperwork do I need to keep to do so? I tried googling this for myself but what I read was kind of confusing since Im driving such a short distance at a time. There will be many times where I fill my tank up and drive 300 miles but would only need to write 30 or so of those miles off on taxes. Any help here is greatly appreciated. edit : to make this more clear Im only asking about the miles driven back and forth between the buildings. I know I cant write off anything from home to work or vice versa.  <response>: Unreimbursed employee business expenses are reported on Form 2106 2106-EZ, and then claimed as part of your itemized deductions on Schedule A, line 21. The deduction is limited to the amount that exceeds 2 of your Adjusted Gross Income.If you dont itemize your deductions there is no benefit.
