How to Claim Mileage on Your Tax Return: Rates, Records, and Rules

To claim mileage on your tax return, track every qualifying mile you drive during the year, multiply the total by the IRS rate that fits the purpose of the trip, and report the result on the form that matches your taxpayer status. For 2026, the business standard mileage rate is 72.5 cents per mile, so a self-employed taxpayer who drove 10,000 business miles reduces taxable income by $7,250.1Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents per Mile, Up 2.5 Cents Lower rates apply to medical and charitable driving, and different reporting forms apply depending on whether the miles were for business, medical care, or volunteer service.

Who Qualifies to Claim Mileage

Not everyone who drives for work can deduct the miles. Federal law permanently bars miscellaneous itemized deductions, and unreimbursed employee business expenses fall in that bucket.2Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions If you receive a W-2 and your employer doesn’t reimburse you for driving your own car on the job, that mileage is not deductible on your federal return.

The taxpayers who can claim mileage are:

  • Self-employed individuals, including sole proprietors, independent contractors, freelancers, and single-member LLC owners driving for business.
  • A narrow group of employees who file Form 2106: Armed Forces reservists, qualified performing artists, fee-basis state or local government officials, and employees with impairment-related work expenses.3Internal Revenue Service. Form 2106 – Employee Business Expenses
  • Anyone with qualifying medical travel who itemizes on Schedule A.
  • Volunteers driving in service of a qualified nonprofit.

If your employer reimburses you at or above the standard mileage rate under an accountable plan, that reimbursement is tax-free and you cannot also deduct the same miles. If reimbursement is below the standard rate, only the categories of employees listed above can deduct the difference.

Which Miles Count and Which Don’t

Commuting between home and your regular workplace is never deductible, no matter how far you drive.4Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses This is where most disallowed mileage claims collapse under audit. Business miles are trips between two work locations, from one client site to another, or from your office to a business meeting.

Three exceptions to the commuting rule matter:

  • If your home qualifies as your principal place of business, drives from home to any other work location in the same trade or business are deductible business miles.
  • If you have a regular office and travel to a temporary work site for the same business, the trip from home to that temporary location counts.
  • If you have no fixed office but work in your metropolitan area, trips from home to a temporary site outside that metro area count.

The home office exception is especially useful. If you run your business from a dedicated space at home, the mileage clock starts the moment you pull out of the driveway to see a client, pick up supplies, or attend a business meeting.

2026 Mileage Rates

The IRS adjusts these rates each year to reflect fuel, insurance, depreciation, and maintenance costs. For miles driven in 2026:

The charitable rate is fixed by statute. The rates apply the same way to gasoline, diesel, hybrid, and fully electric vehicles. Parking fees and tolls paid during a qualifying trip are deductible on top of the mileage rate.

Standard Mileage Rate or Actual Expenses

For business driving you pick one of two methods each year. The choice comes down to how much your vehicle costs to run and how many business miles you put on it.

The Standard Mileage Rate

Multiply total business miles by 72.5 cents. That’s the whole calculation. The rate is built to cover gas, insurance, depreciation, repairs, and general wear in one number, so you don’t track receipts for those items. It tends to work well for a fuel-efficient car driven heavily for business, because the per-mile depreciation baked into the rate often exceeds actual depreciation on a modestly priced vehicle.

If you want the option of using the standard rate in later years, you have to choose it in the first year you place the vehicle in business service.5Internal Revenue Service. Topic No. 510, Business Use of Car After that first year, you can switch between methods annually.

Actual Expenses

Add up everything you spent operating the vehicle during the year: gas, oil, tires, repairs, insurance, registration, lease payments, and depreciation if you own it. Then calculate your business-use percentage by dividing business miles by total miles driven, and multiply total expenses by that percentage.

If you spent $9,000 running the car and drove 60% of your miles for business, the deductible portion is $5,400. Actual expenses tend to favor taxpayers with expensive vehicles or high operating costs, but the method requires meticulous receipts and a depreciation calculation.5Internal Revenue Service. Topic No. 510, Business Use of Car

Certain situations lock you out of the standard rate entirely, including operating five or more vehicles for business at the same time, having previously claimed MACRS depreciation or a Section 179 deduction on the vehicle, or having used actual expenses on a car leased after 1997.4Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses If any apply, actual expenses are your only option for that vehicle.

Records the IRS Expects You to Keep

For every vehicle expense deduction, you have to substantiate four things: the amount, the time and place, the business purpose, and the business relationship of anyone involved.6Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses In practice, that means a mileage log with the date of each trip, where you went, why the trip was business-related, and the miles driven.

Record entries at or near the time of each trip. A log reconstructed months later carries far less weight if the IRS asks questions. There’s no required format, so a spreadsheet, a notebook in the glove box, or a tracking app all work. If you use an app, make sure the records can be printed and produced on request.

Note your odometer reading at the start and end of the year. That establishes total miles driven, which the IRS can compare against your claimed business miles to see whether the ratio is plausible. Claiming 90% business use on a car you also drive to the grocery store and school pickup will draw scrutiny. Keep toll and parking receipts separately, since those are deductible on top of the mileage rate.

Medical and Charitable Mileage

Medical mileage covers driving for diagnosis, treatment, and prevention of disease, including doctor appointments, physical therapy, lab work, and pharmacy pickups. The 2026 rate is 20.5 cents per mile. You can claim it only if you itemize on Schedule A, and only the portion of total medical expenses that exceeds 7.5% of your adjusted gross income is deductible.7Internal Revenue Service. Publication 502 – Medical and Dental Expenses On a $60,000 AGI, the first $4,500 in medical expenses produces no tax benefit, so medical mileage typically only matters when other medical costs are already substantial.

Charitable mileage applies when you drive while performing volunteer services for a qualified nonprofit, at 14 cents per mile. It also requires itemizing on Schedule A. The driving has to be in direct service of the charity’s mission, not for your own convenience in getting to the organization.

Where to Report Mileage on Your Return

The form depends on why you drove and your taxpayer status.

Self-Employed Business Mileage

Enter vehicle information in Part IV of Schedule C (Form 1040), including total business miles, commuting miles, and other personal miles.8Internal Revenue Service. Schedule C (Form 1040) – Profit or Loss From Business The calculated deduction goes in the expenses section of Schedule C. Under the standard rate, it’s business miles times 72.5 cents. Under actual expenses, work through the depreciation and expense allocation before entering the total.

Eligible Employees

Armed Forces reservists, qualified performing artists, fee-basis government officials, and employees with impairment-related work expenses use Form 2106 to calculate the deduction, which then flows to Schedule 1 (Form 1040), line 12.3Internal Revenue Service. Form 2106 – Employee Business Expenses The form asks whether you have written records and requires answers about personal use of the vehicle.

Medical and Charitable Mileage

Both go on Schedule A. Medical mileage is folded into total medical expenses subject to the 7.5% AGI floor. Charitable mileage falls under charitable contributions. Taking the standard deduction instead of itemizing means you cannot claim either.

Penalties for Inflated or Fabricated Claims

Overstating business miles doesn’t just cost you the deduction. The IRS applies a 20% accuracy-related penalty on the portion of the tax underpayment caused by negligence or a substantial understatement of income, and failing to keep adequate mileage records is specifically identified as negligence. An understatement is substantial if it exceeds the greater of $5,000 or 10% of the tax that should have been shown on the return.

If the IRS determines you intentionally inflated mileage, the civil fraud penalty is 75% of the underpayment, and there is no statute of limitations on a fraudulent return. The accuracy-related penalty can be avoided by showing reasonable cause and good faith, but that defense falls apart quickly when the mileage log doesn’t exist or was clearly built after the fact. Contemporaneous records are the only reliable protection you have if the return is questioned.
