TurboTax asks for your business mileage to calculate the business percentage use of the vehicle.
If you have no business mileage then you have no business use of the vehicle.
If you have 100% business use of the vehicle then the total mileage and the business mileage are the same number, and personal and commute mileage are zero.
It appears the percent business use is calculating wrong or I am missing something obvious.
I have 13,661 miles of business of a total 28,200 miles driven in 2019.
Line 9 of the Car and Truck Expenses instructs me to divide line 6 (business miles) by 5c (total miles) to arrive at business use:
13,661/28,200 is 48.44% but Turbo Tax is calculating 28.26% on Line 9. That's a material difference in the refund I receive for allocating my car interest expense to my business.
Can you help me understand why this calculating differently than the instruction on the form?
