2022 Tax Year. Husband/wife have small LLC Partnership business selling to retailers, and direct customer sales via trade shows and requests. We have 5 vehicles, 2 or 3 are used about 10% of annual miles for business travel. It's beyond me to keep track of every vehicle cost item, I do a lot myself, we pay cash for the vehicles, most have lifetime registration fee and of course 1 insurance bill. I know the exact business and annual miles used by each vehicle. I would like to say the owner of a car (husband's or wife's) contributed the value of the IRS mileage for business miles and the business "didn't get the cash value" because it was spent/expensed to use the vehicle. So for 200 miles of the husband's car driven to trade show, the husband contributed $0.585*200=$117 to his % ownership of business and the business had $117 of vehicle expense. Each car and owner gets treated similarly. I'm not trying to be clever, actual annual vehicle costs mean little compared to average annual lifetime operating cost.
