2025 IRS Standard Mileage Rates
The IRS updates the standard mileage rate annually to reflect changes in the cost of operating a vehicle. For 2025, the business mileage rate is $0.70 per mile — an increase from the 2024 rate of $0.67 per mile. This rate covers fuel, depreciation, insurance, and maintenance.
The medical and moving mileage rate for 2025 is $0.21 per mile, applicable to travel for qualified medical care or for active-duty military members relocating under orders. The charitable mileage rate remains $0.14 per mile — this rate is set by Congress and has not changed in many years.
You must keep a contemporaneous mileage log to substantiate your deduction. Your log should record the date of each trip, the destination, the business purpose, and the number of miles driven. Apps like MileIQ, Everlance, or even a simple spreadsheet work well. Without documentation, the IRS can disallow your entire mileage deduction.
What Counts as a Business Mile?
A business mile is any driving you do for legitimate business purposes — not commuting. Driving from your home to your regular office does not qualify. However, driving from your office to a client's location, between job sites, to pick up business supplies, or to attend a business meeting all count as deductible business miles.
If you work from a home office that qualifies as your principal place of business, then any driving you do from home for business purposes — including trips to clients and suppliers — is fully deductible. This is one of the significant tax advantages of the home office deduction combined with the mileage deduction.
The standard mileage method is simpler than the actual expense method (which requires tracking gas, insurance, repairs, and depreciation separately). You can choose either method in the first year you use a vehicle for business, but if you use the standard mileage rate in the first year, you can switch to actual expenses in later years. The reverse is not always permitted — check with your CPA before switching methods.
