Not sure how much information is needed, but let’s say something comes up that requires substantial driving which the employee is willing to do with their personal car.
Beyond their wage what do you think is a reasonable approach to compensating them for the use of their car? Specifically due to depreciation, wear and tear.
If it makes a difference I’m interested in the theoretical approach rather than what I can get away with or something like that.
When I did a temporary W-2 driving gig using my own car, they paid me the standard mileage rate, which I think is .65 cents a mile this year, and they were insured in case anything happened while I was driving for them. If the mileage is too high, plus the insurance, it may make more sense for you to rent them a car like one of the other posts said. It would depend on how many miles they were going to be driving.
