Hello again Customer,
That is simply not the case. Transporting tools and equipment has nothing to do with whether or not you can claim a mileage allowance
for your travel.
In order to claim credit
for your mileage, you must be traveling away from the area where you normally work, to a temporary work location, and the temporary work location must be outside of the normal area where you work. So if you normally work on the east side of Philadelphia, and then they send you to a job on the west side of the city, that is not considered a new work location, as you are still in the Philadelphia area which is your tax home.
You must actually be traveling away from the general area that is considered to be your tax home before mileage can be claimed.
If during the course of your work day, your employer would ask you to use your personal
truck to take supplies or equipment to another jobsite, then you could deduct the cost of the miles you traveled from one job site to another, but you cannot deduct the miles traveled between your residence and your first job site location of the day, assuming that job site is in your tax home area.
Transporting tools and equipment has no affect on whether or not you may claim the mileage that you commute between your home and your regular place of work.
