I'd like to ensure that you can keep your records accurate.
QuickBooks keeps track of your total mileage so you can claim the correct deduction. You can also categorize any vehicle-related expenses so you have all the info you need when you file your taxes.
To verify if mileage reimbursement can be deducted on taxes, I'd recommend reaching out to your accountant. They can give you the best course of action to be taken on your situation.
