Understanding the 2024 IRS Standard Mileage Rates

Effective January 1, 2024, the Internal Revenue Service (IRS) updated the optional standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical, or moving purposes. Accurately tracking your mileage is essential for maximizing your tax deductions or ensuring fair employer reimbursement.

The standard mileage rate for business use in 2024 is 67 cents per mile, which is an increase of 1.5 cents from 2023. This rate adjustment accounts for changes in fuel prices, insurance costs, and general vehicle maintenance expenses.

2024 Official Rate Breakdown

Purpose of Drive	2024 Rate per Mile	Comparison to 2023
Business	67 cents	Increased 1.5 cents
Medical / Moving*	21 cents	Decreased 1 cent
Charitable Service	14 cents	Unchanged (set by statute)

*Note: The moving expense deduction is currently available only to active-duty members of the Armed Forces moving under orders to a permanent change of station.

How to Calculate Your Reimbursement

The formula for calculating your mileage deduction or reimbursement is straightforward:

(Total Miles Driven × IRS Rate) + Parking & Tolls = Total Amount

For example, if you drove 500 miles for business purposes in 2024 and spent $25.00 on parking:

• Mileage Cost: 500 miles × $0.67 = $335.00
• Additional Costs: $25.00
• Total Claim: $360.00

Documentation Requirements

To successfully claim these deductions on your taxes or get reimbursed by an employer, the IRS requires timely and accurate records. Your mileage log should include:

• Date: The specific date of the trip.
• Mileage: Odometer readings (start and end) or total distance.
• Purpose: The business reason for the trip (e.g., "Client meeting with XYZ Corp").
• Destination: Where you drove.

Estimates are generally not accepted during an audit. Using a digital mileage tracking app or a physical logbook kept in your vehicle is highly recommended.

Common Questions

Can I deduct commuting costs?

No. The IRS defines commuting as driving from your home to your regular place of work. These miles are considered personal expenses and are never deductible, regardless of how far you live from your workplace.

Can I use the standard rate if I lease my car?

Yes, but you must use the standard mileage rate for the first year you use the car for business. In later years, you can choose to use the standard rate or actual expenses. However, if you choose the standard rate for a leased car, you must stick with it for the entire lease period.
