Understanding the Going Rate for Mileage Reimbursement in 2024
Whether you are an employee using a personal vehicle for work, a freelancer, or a business owner managing expenses, understanding the current mileage reimbursement rates is crucial for accurate financial reporting and tax deductions. The IRS updates these standard mileage rates annually to reflect the costs of operating an automobile.
Official 2024 IRS Standard Mileage Rates
Effective January 1, 2024, the Internal Revenue Service issued Notice 2024-08, which established the following standard mileage rates:
- Business Use: 67 cents per mile (up 1.5 cents from 2023).
- Medical or Moving: 21 cents per mile (decreased by 1 cent from 2023).
- Charitable Organizations: 14 cents per mile (set by statute and remains unchanged).
How is the Reimbursement Calculated?
The calculation for mileage reimbursement is a straightforward multiplication equation using the formula:
Total Miles Driven × Rate per Mile = Total Reimbursement
For example, if you drive 1,000 miles for business purposes in 2024:
- 1,000 miles × $0.67 = $670.00 reimbursement.
Business vs. Commuting Miles
It is important to note that the IRS does not allow deductions or reimbursements for commuting expenses. Commuting refers to the drive between your home and your regular place of business. Reimbursement generally applies to:
- Driving from your office to a client site.
- Driving from your office to a temporary work location.
- Driving between two different temporary work locations.
Why Did the Rate Change for 2024?
The IRS determines the standard mileage rate based on an annual study of the fixed and variable costs of operating an automobile. This includes expenses such as:
- Gasoline and oil
- Depreciation of the vehicle
- Insurance and registration fees
- Maintenance and repairs
The increase to 67 cents per mile for business use in 2024 reflects the fluctuating costs in the automotive market, particularly regarding fuel prices and vehicle maintenance costs observed over the previous year.
Record Keeping Requirements
To substantiate mileage deductions or reimbursements, the IRS requires timely and accurate records. A valid mileage log should include:
- The date of the trip.
- The starting and ending location.
- The business purpose of the trip.
- The total mileage driven.
- Odometer readings (start and end).
Using a digital mileage tracker or our 2024 Mileage Reimbursement Calculator above can help you estimate your potential reimbursement quickly.
