<prompt> Human: My company pays cash the IRS standard mileage rate for mileage when we have to drive farther away than a regular work site.Is this taxable income?Do I have to report it on my return? I am not sure if it will be on my W-2 so I want to start logging it for that purpose if I need.  <response>: There are a few stipulations, but generally you do not have to report the reimbursement as income.
