That also brings up another point. This means you’re carrying passengers for hire so your state may require a CDL of some sort.
Bingo! That’s the point I was going to make. The government sets a mileage reimbursement amount that accounts for fuel and vehicle maintenance etc. Last I looked it was $0.52. Easy enough for you to check and use that as a guide for your transportation costs. Insurance and all the other business expenses will have to be weighed in too. Once you accept money, you’re operating a business and therefore subject to all that goes along with it. People are always nice until something goes wrong and the lawyers start bending their ears (I can get you the money you DESERVE…)
