How does mileage reimbursement work?
In the US, UK, and many other countries, business expenses are usually tax-deductible. When taxpayers travel by plane, train, or taxi, they can claim the money back and their employer can claim tax relief.
Corporate mileage reimbursement schemes extend this benefit to personal vehicles. When employees use their personal car, van, or bike for day-to-day business activities, they can claim back the cost without paying income tax.
An important point to note here is that mileage reimbursement isn’t designed to cover commuting to and from work. It is designed to cover the journeys that employees make
during work, specifically those with a business purpose (
unfortunately you can’t claim travel expenses for going to the gym or picking up food at lunchtime).
The Internal Revenue Service (IRS), which regulates mileage reimbursement in the US, states that to qualify as a business journey, a trip must be 1) ordinary, which means it is common or accepted in the industry, and 2) necessary, which means it is appropriate or helpful to the company.
These can include a variety of trips, including:
- To go and see a client
- To attend a meeting
- To go and see another employee or manager
- To go and collect business supplies
- To run an errand on behalf of the company
The mileage reimbursement regulations also state that the majority of the journey has to be work-related—so if you stop off to pick up some office equipment on the way back from visiting your parents, that doesn’t count.
It’s important to stress the importance of good record-keeping at this point. In the US, the IRS expects employees to maintain a mileage log, with four distinct details:
- The time and date of each journey.
- The total distance covered (odometer readings can be useful for noting business miles).
- The destination of each drive.
- A brief description of the purpose.
The mileage log can be written down with pen or paper, or on a computer. The important thing is that they are noted at the time.
