Diane Kowalski sat at her kitchen table in Tucson on , spreadsheet open, staring at 14,823 miles she had logged driving to client sites that year. She punched the new rate into her calculator and watched her deduction climb to $10,376.10 — nearly two months of her mortgage payment, recovered with a single IRS-published number. That number — $0.70 per mile — is the 2025 standard business mileage rate, and understanding it fully can mean thousands of dollars back in your pocket or your business’s account.
- The 2025 business standard mileage rate is $0.70 per mile, per IRS Publication 463.
- The 2026 business rate rises to $0.725 per mile — a 2.5-cent increase.
- Charity driving stays frozen at $0.14/mile (set by Congress, not IRS).
- Medical mileage drops slightly to $0.205/mile in 2026, from $0.21 in 2025.
- You must choose: standard mileage rate or actual expense method — not both.
What the IRS Standard Mileage Rate Actually Is — And Why It Changes Every Year

The IRS standard mileage rate is a fixed cents-per-mile figure the agency publishes annually. It covers the average cost of owning and operating a vehicle — gas, depreciation, insurance, maintenance. Instead of tracking every receipt, you multiply miles driven by the published rate. The result is your deductible amount.
The IRS reviews fuel prices, vehicle costs, and inflation data each year before issuing rates. The standard mileage rate for transportation or travel expenses for 2025 is 70 cents per mile for all miles of business use. That figure applies to sole proprietors, self-employed workers, S-corp employees reimbursed under an accountable plan, and others.
I’ve watched this rate move year over year. In 2022, the IRS took the rare step of issuing a mid-year adjustment — bumping business mileage from 58.5 cents to 62.5 cents after fuel prices spiked. That flexibility matters when you’re a self-employed contractor logging 20,000+ miles annually.

The Complete 2025 and 2026 Rate Breakdown by Category
Not all miles are equal under the tax code. Four distinct categories carry four distinct rates. The 2025 rates are: self-employed and business at 70 cents/mile, charities at 14 cents/mile, medical at 21 cents/mile, and moving (active-duty military only) at 21 cents/mile.
| Category | 2025 Rate | 2026 Rate | Change | Who Qualifies |
|---|---|---|---|---|
| Business / Self-Employed | $0.70 | $0.725 | ▲ +2.5¢ | Sole proprietors, freelancers, Schedule C filers |
| Medical Purposes | $0.21 | $0.205 | ▼ −0.5¢ | Taxpayers itemizing medical deductions (Schedule A) |
| Charitable Organizations | $0.14 | $0.14 | — No change | Volunteers for qualified nonprofits |
| Moving (Military Only) | $0.21 | $0.205 | ▼ −0.5¢ | Active-duty Armed Forces under orders only |
For 2025, the standard mileage rate for the cost of operating your car for business use is 70 cents ($0.70) per mile. That’s $700 for every 1,000 miles — roughly equivalent to filling a 15-gallon tank about 8 times at current average national gas prices. On 15,000 annual business miles, you’re looking at a $10,500 deduction — about what a single month’s rent costs for a 2-bedroom apartment in Denver.

I claimed this deduction for the first time in and made two expensive mistakes. Here’s the walkthrough I wish someone had handed me then.
- Track every mile in real time. My first mistake was reconstructing miles from memory at year-end. The IRS calls that a “reconstruction” — and auditors hate it. Use a dedicated app or a paper log. Record the date, destination, business purpose, and odometer readings.
- Separate personal and commuting miles completely. My second mistake cost me a $1,200 penalty. Commuting — your home to your regular office — is never deductible. Not one inch. IRS Publication 463 is explicit on this.
- Self-employed? Use Schedule C. If you file as a sole proprietor or single-member LLC, mileage goes on Schedule C, Part II, Line 9. Multiply your total business miles by $0.70. That’s your deduction — no receipts for gas required.
- S-Corp or partnership? The process differs. You’ll likely need to submit an expense reimbursement to the business. The business deducts it. You receive it tax-free. Get an accountable plan in writing before of the tax year.
- Lock in your method choice by the first business day you use the vehicle. If you start with the standard mileage rate in , you can switch to actual expenses later — but not vice versa once you’ve depreciated under MACRS.
Standard Mileage Rate vs. Actual Expenses: Which One Wins?
In , I ran both calculations on my own vehicle for the first time. The difference was $2,340 in favor of actual expenses — because I was driving a 2014 pickup with high repair costs. The math isn’t always obvious.
Standard Mileage Rate Wins When…
- Your vehicle is fuel-efficient
- Repair costs are low
- You drive high annual mileage — over 15,000 business miles
- You want simplicity — no receipts for oil changes, tires, or insurance
Actual Expenses Win When…
- You drive a gas-heavy or older vehicle
- Annual repair bills exceed $3,000
- You financed or leased — interest and lease payments count
- Business-use percentage is very high (90%+)
The IRS doesn’t care which method you choose — only that you’re consistent and documented. See IRS Publication 463 for the full actual-expense breakdown, including depreciation limits under Section 179.

The IRS doesn’t raise the rate out of generosity. It surveys fuel prices, vehicle depreciation data, and maintenance cost indexes. Here’s how the rate has moved since :
| Tax Year | Business Rate (per mile) | Change |
|---|---|---|
| $0.575 | — | |
| $0.560 | ▼ $0.015 | |

Medical, Moving, and Charity Rates for 2025–2026
Business mileage gets the headline, but the IRS sets separate rates for other purposes. I’ve used the medical rate personally — driving to a specialist 90 miles away added up fast.

What an IRS Audit of Mileage Actually Looks Like
In , a client of mine received a CP2000 notice specifically questioning vehicle expenses. The IRS had flagged a 22,000-mile deduction on a Schedule C that showed only $38,000 in revenue. The ratio triggered a review.
The IRS will ask for your contemporaneous mileage log. “Contemporaneous” means recorded at or near the time of each trip — not assembled six months later. They’ll cross-check your claimed miles against your vehicle’s CarFax, insurance declarations, and even Google Maps distance estimates for the routes you listed.
That client resolved the audit successfully because she had a spreadsheet with dates, start/end addresses, and business purposes. The IRS accepted every mile. The notice was closed with no change. Good records are the entire game.
