all my jobs are temporary and can be anywhere from 10 miles away to a different state. Can I deduct my mileage over 2% of my AGI?
You can deduct the mileage if there was a location you needed to report to, such as the staffing employment office, before you drove to the work location.
In that example you can claim the mileage from the staffing office to the work place and back.
According to the IRS:
"You can deduct daily transportation expenses incurred going
between your residence and a temporary work station outside the metropolitan
area where you live....
...You can’t deduct daily transportation costs between your home and temporary work sites within your metropolitan area. These are nondeductible commuting expenses.
Generally, a metropolitan area includes the area within the city limits and the suburbs that are considered part of that metropolitan area.
If your employment at a work location is realistically expected to last (and does in fact last) for 1 year or less, the employment is temporary unless there are facts and circumstances that would indicate otherwise."
