Who Should Use This Section
There are three situations for vehicle expenses and mileage‐
1. Your business owns the vehicle. If this is your situation, do not use this form since actual expenses associated with your business vehicle will be detailed (and deducted) in your business expenses.
2. You own the vehicle, and you want to deduct the mileage allowance (or deduct the mileage reimbursement as a business expense).
3. You own the vehicle, and you want to deduct the actual expenses associated with the business vehicle such as gas, insurance, lease payments, maintenance, etc. (or deduct the vehicle expense reimbursement as a business expense)
In most cases, using the mileage rate as a deduction or reimbursement is preferred over actual expenses. Traveling salespeople and other W‐2 employees who historically deducted mileage on Form 2106 as a unreimbursed expense are no longer allowed to deduct mileage (this is part of the Tax Cuts and Jobs Act of
2017). A company may still reimburse you up to the mileage rate without it being considered income to you, but any difference cannot be deducted due to the recent tax reform (sorry).
