What Is Mileage Reimbursement?
Answer-first definition page covering what reimbursement is, how it is calculated, and what paperwork usually comes next.
Short answer
Mileage reimbursement is money paid back for business use of a personal vehicle, usually by multiplying eligible miles by a cents-per-mile rate or another documented reimbursement method.
At a glance
- A reimbursement is an employer or program payment. A mileage deduction is a tax concept and is not the same thing.
- The three practical pieces are eligibility, the rate or method used, and the records that support the trip.
- Most users asking this question immediately need one of three follow-ups: the current rate, a calculator, or a reimbursement form.
What the phrase means in practice
The phrase usually refers to business driving in a personally owned vehicle. A worker logs the trip, applies the employer's rate or reimbursement method, and then submits the claim through an expense or payroll workflow.
That is why definition pages do better when they answer the next question immediately: how the payment is calculated and what paperwork goes with it.

Common questions
Is mileage reimbursement the same as a mileage deduction?
No. Reimbursement is a payment workflow between worker and employer, while a deduction is a tax-return workflow.
Do I need a reimbursement form if I already keep a mileage log?
Usually yes. The mileage log proves the trips, while the reimbursement form packages the claim for approval and payment.
