For tax purposes, you must identify the vehicle(s) you are using and track odometer readings at least annually.
Deductr can track more than one vehicle.
As you track your mileage, you are then able to update the latest or ending odometer reading, on any vehicle, any time you choose.
When you update your ending odometer, Deductr will calculate both the "standard mileage rate" and the "actual" methods. The greater of the two will be used in the estimated tax savings calculation.
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.
