Let me share some information on how QuickBooks handles your tracked mileage.
When you record your mileage in QuickBooks, it will display the total distance you've covered and the total business miles you've incurred with its equivalent potential deduction. Your personal-related mileage is not included in the deduction. Here's how your mileage is calculated:
Total Business miles X Standard Mileage Rates = Potential Deduction
If you're total tracked mileage is 193.30 mi but only 166.2 mi is marked as Business miles, then your potential deduction will only show $95.56.
