For tax purposes, a specific vehicle must be declared to get the deduction. Deductr tracks just one vehicle -- the one you will use most of the time for business.
As you track your mileage, you are then able to update the latest or ending odometer reading any time you chose. When you update your ending odometer, we will calculate the greatest deduction possible for you.
Consult your tax professional to see if this fits your circumstances. This is not to be taken as tax advice. Please refer to our End User License Agreement.
