If you don't want to take the standard IRS deduction, you would probably have to be able to document every single expense (gas, oil, repairs, maintenance, registration, etc) AND document the depreciation on the vehicle based on mileage AND THEN document how much all of that was used for business vs. personal. The IRS really doesn't want to go down that rabbit hole, and neither should you - which is why they come up with a standard deduction. As you said, you can't do both. |
