2025 IRS Standard Mileage Rates: What’s New?

The Internal Revenue Service (IRS) updates standard mileage rates annually to reflect the changing costs of operating an automobile. These rates account for a comprehensive list of expenses, including depreciation, insurance, repairs, tires, maintenance, gas, and oil. The IRS released the 2025 rates in Notice 2025-05, effective January 1, 2025.

For the 2025 tax year, the standard mileage rates are:

  • 70 cents per mile for business use. This represents an increase of 3 cents from the 2024 rate of 67 cents per mile.
  • 21 cents per mile for medical or moving purposes. This rate remains unchanged from 2024. Note that the moving deduction is currently limited to qualified active-duty members of the Armed Forces.
  • 14 cents per mile for charitable organizations. This rate is set by statute and remains fixed at 14 cents, consistent with previous years.

These rates apply to cars, vans, pickups, and panel trucks. The increase in the business rate reflects rising costs associated with vehicle ownership and operation, ensuring that taxpayers are adequately compensated for the wear and tear on their personal vehicles.

How to Use the Mileage Calculator

Our calculator is designed to be simple yet accurate, allowing you to switch between tax years and purposes seamlessly. Follow these steps to get your estimate:

  1. Select Tax Year: Choose "2025" for current driving activities or "2024" if you are retroactively calculating deductions for your previous year's tax return.
  2. Select Purpose: Choose the reason for your travel (Business, Medical/Moving, or Charity). Each category corresponds to a specific IRS-defined rate.
  3. Enter Miles: Input the total number of miles driven for that specific purpose. Ensure this matches your logbook records.
  4. View Result: The calculator will instantly display your estimated deduction or reimbursement value in US dollars.

Standard Mileage Rate vs. Actual Expenses: Which is Better?

When claiming a deduction for vehicle use, taxpayers generally have two options: the Standard Mileage Rate or the Actual Expenses Method. Choosing the right one can significantly impact your tax savings.

Option 1: Standard Mileage Rate

This is the most popular method due to its simplicity. You simply multiply your business miles by the standard rate (e.g., 70 cents in 2025). This single rate is designed to cover all operating costs, including:

  • Gasoline and oil
  • Insurance premiums
  • Registration fees
  • Repairs and maintenance
  • Tires
  • Depreciation

Pros: Less record-keeping (only mileage logs required), easy to calculate, and you can switch to the actual expenses method in future years (if you own the car).
Cons: You cannot deduct depreciation separately, and if your car has very high operating costs (e.g., a gas-guzzler or expensive repairs), you might get a smaller deduction than with actual expenses.

Option 2: Actual Expenses Method

With this method, you track every single expense related to your vehicle and deduct the business percentage of those costs. If you use your car 80% for business, you can deduct 80% of your total auto expenses. This requires detailed record-keeping for:

  • Gas and oil
  • Insurance premiums
  • Repairs and maintenance
  • Tires
  • Registration and license fees
  • Depreciation (Section 179 or MACRS)
  • Garage rent
  • Lease payments (if applicable)
  • Tolls and parking fees (these are deductible under both methods)

Pros: Potentially higher deduction for newer, more expensive vehicles or vehicles with high maintenance costs.
Cons: extensive record-keeping required. If you choose this method in the first year, you generally cannot switch back to the standard mileage rate for that vehicle in future years.

Who Can Claim the Business Mileage Deduction?

The business mileage deduction is primarily available to:

  • Self-Employed Individuals: Sole proprietors, independent contractors, and gig workers (e.g., Uber/Lyft drivers, DoorDash couriers) who file Schedule C can deduct mileage driven for business purposes.
  • Small Business Owners: Partners in partnerships and S-corporation shareholders may also be able to claim deductions depending on their specific business structure and reimbursement policies.
  • Employees (State-Level Only): Following the Tax Cuts and Jobs Act (TCJA) of 2017, W-2 employees can no longer deduct unreimbursed business expenses on their federal tax returns. However, some states (like California, New York, and others) may still allow these deductions on state income tax returns. Check with a tax professional in your state.

Record-Keeping: The "Golden Rule" of Tax Deductions

Regardless of which method you choose, the IRS requires timely, accurate, and written records. The "Cohan Rule" (which allows estimates) rarely applies to travel and vehicle expenses in modern audits. You cannot simply estimate your mileage at the end of the year; you must keep a contemporaneous log.

Your mileage log must include the following details for every business trip:

  • Date of the trip.
  • Starting point and destination.
  • Business purpose of the trip (e.g., "Meeting with Client X," "Delivery to Site Y").
  • Total miles driven.
  • Odometer readings (start and end of the year) to determine total usage.

Pro Tip: Use a mileage tracking app on your smartphone to automate this process. Many apps use GPS to track drives and allow you to classify them as business or personal with a single swipe.

Common Mistakes That Trigger IRS Audits

The vehicle deduction is a common target for IRS audits because it is often overstated or poorly documented. To avoid raising a red flag, steer clear of these pitfalls:

  • Estimating or Rounding: A mileage log that shows "100 miles, 50 miles, 20 miles" looks fabricated. Real odometer readings are rarely perfect round numbers. Record the exact tenths of a mile.
  • Claiming 100% Business Use: It is highly unlikely that a personal vehicle is used 100% for business and 0% for personal reasons (like commuting or grocery shopping). If you only own one car, claiming 100% business use is almost a guaranteed audit trigger.
  • Inconsistent Logs: If your log shows you were in New York on Monday but your credit card statement shows a gas purchase in Florida on the same day, you have a problem. External data must match your log.
  • Missing the Purpose: Simply writing "business" is not enough. You need to specify "Meeting with Client Smith" or "Delivery to 123 Main St."

Mileage Tracking Apps vs. Paper Logs

In the past, every driver kept a small notebook in their glovebox. Today, technology has made this easier, but also more scrutinizable.

Paper Logs:
Pros: Cheap, doesn't require a battery, simple.
Cons: Easy to lose, tedious to maintain, prone to math errors, easy to forget entries.

Tracking Apps (e.g., MileIQ, Everlance):
Pros: Automatic GPS tracking as soon as you start driving, easy classification (swipe left/right), generates IRS-compliant PDF reports, backs up to the cloud.
Cons: Monthly subscription fee, requires phone battery and GPS signal.

Verdict: For anyone driving more than a few times a month, an app pays for itself by catching trips you would have otherwise forgotten to record.

How Depreciation Works if You Switch Methods

A critical nuance often overlooked is how depreciation affects your ability to switch between methods.

If you use the Standard Mileage Rate, a portion of that rate (e.g., 30 cents in 2025) is considered "depreciation." This means the basis of your car is reduced by that amount for every business mile you drive.

If you start with the Standard Mileage Rate in Year 1, you can switch to the Actual Expenses Method in Year 2. However, you must calculate the car's remaining basis by subtracting the depreciation "allowed or allowable" under the standard mileage rate for Year 1. You cannot simply start depreciating the full purchase price again.

Conversely, if you start with the Actual Expenses Method (specifically if you use accelerated depreciation like MACRS or Section 179) in Year 1, you are generally barred from ever using the Standard Mileage Rate for that vehicle in the future.
