2025 IRS Mileage Rates in Effect: What Business Owners Should Know Before Year-End
As we head into the final stretch of 2025, many business owners and self-employed individuals are reviewing their travel and vehicle expenses before closing out the year. One key factor that continues to impact deductions and reimbursements is the IRS standard mileage rate, which increased earlier this year.
The IRS standard mileage rate for business use rose to 70 cents per mile on January 1, 2025 — a 3-cent increase from 2024. The updated rate reflects the higher costs of owning and operating a vehicle, including fuel, maintenance, insurance, and depreciation.
If you’ve driven your personal vehicle for business, charitable, medical, or moving purposes in 2025, here’s what you need to know to ensure you’re taking full advantage of your deductions.
Current 2025 Standard Mileage Rates
The IRS optional standard mileage rates, effective since January 1, 2025, are as follows:
- 70 cents per mile for business use (up 3 cents from 2024)
- 21 cents per mile for medical purposes (unchanged from 2024)
- 21 cents per mile for moving purposes (for qualified active-duty members of the Armed Forces)
- 14 cents per mile for charitable purposes (unchanged, set by law)
These rates apply to all vehicle types — including fully electric, hybrid, gasoline, and diesel-powered vehicles.
How the Mileage Rate Affects Your 2025 Tax Deductions
If you’ve been tracking mileage for your business throughout 2025, this higher rate means a larger potential deduction at tax time. For example:
- Driving 10,000 business miles this year could yield a $7,000 deduction under the standard mileage method.
- This method simplifies recordkeeping since you don’t need to track every individual car expense like gas, repairs, and depreciation — just your mileage.
However, you must have detailed, contemporaneous mileage logs to substantiate your deduction. This includes the date, destination, purpose of the trip, and miles driven.
How the IRS Calculates These Rates
Each year, the IRS reviews the fixed and variable costs of operating a vehicle to determine the business mileage rate. This includes depreciation, insurance, repairs, and fuel.
The medical and moving rates are based solely on variable costs, while the charitable rate remains fixed at 14 cents per mile under federal law.
These calculations ensure the mileage rate reflects real-world costs and keeps pace with economic trends like fuel prices and inflation.
Important Tax Law Reminders
It’s worth noting that employees can no longer deduct unreimbursed business mileage under the Tax Cuts and Jobs Act (TCJA).
However, self-employed individuals, gig workers, and small business owners can still deduct mileage related to business operations.
Additionally:
- Only active-duty military members can claim moving expenses.
- You can choose between the standard mileage rate or actual vehicle expenses, whichever provides the greater deduction.
Rules for Using the Standard Mileage Method
If you opted to use the standard mileage rate for your vehicle in 2025, make sure you’re following these key rules:
- You must have chosen the standard mileage method in the first year your vehicle was used for business.
- After the first year, you may switch between the standard mileage rate and actual expenses (for owned vehicles).
- For leased vehicles, you must continue using the standard mileage rate for the entire lease period, including renewals.
