What are the 2026 standard mileage rates by period?

The two-period structure for 2026 is unusual enough that it’s worth laying out clearly. Most years the IRS sets one rate in December and it holds all year. The mid-year adjustment reflects fuel and vehicle cost pressures that moved enough to trigger a revision.

Period	Business	Medical / Moving	Charitable
Jan 1–Jun 30, 2026	72.5¢/mile	21¢/mile	14¢/mile
Jul 1–Dec 31, 2026	76¢/mile	22¢/mile	14¢/mile

The charitable rate stays at 14¢ because Congress sets it by statute — the IRS cannot adjust it administratively the way it adjusts the other rates.

One figure that most taxpayers overlook: a portion of the business rate is treated as deemed depreciation, which reduces your vehicle’s cost basis. The exact per-mile depreciation amount for 2026 is specified in the IRS Revenue Procedure/Notice. Every mile you claim under the standard rate chips away at your basis, and that matters when you sell the vehicle. A lower basis means a higher taxable gain at sale — so the deduction you take today has a downstream cost you should plan for.

Rate callout: The July 1 business rate of 76¢/mile is the rate that applies to every qualifying business trip taken on or after July 1, 2026. Trips before that date use 72.5¢. Keep your log dates accurate — the IRS will check them.

Who can use the standard mileage rate in 2026?

Not everyone qualifies. The IRS has specific rules about who may use the standard mileage rate, and a few common situations disqualify it entirely.

You generally may use the standard mileage rate if you:

Are self-employed and use a personally owned vehicle for business
Own or lease the vehicle (with different rules for each — see below)
Use five or fewer vehicles simultaneously for business (fleet operators do not qualify)
Did not claim a Section 179 deduction or special depreciation allowance on the vehicle in the year it was placed in service
Did not claim actual expenses in the first year the vehicle was used for business

Common situations that disqualify the standard mileage rate:

You operate a fleet of six or more vehicles at the same time
You previously claimed Section 179 expensing or bonus depreciation on the vehicle
You are an employee with unreimbursed work-related driving

That last point trips up a lot of W-2 employees. IRS guidance on who can deduct car expenses is direct: under current tax law, employees generally cannot deduct unreimbursed vehicle expenses as an itemized deduction. The Tax Cuts and Jobs Act suspended that deduction through 2025, and it remains unavailable for most employees in 2026. Self-employed taxpayers and business owners filing Schedule C are in a different position — they can still claim the deduction.

For leased vehicles, you may use the standard mileage rate, but you must use it for the entire lease period (including renewals) if you choose it in the first year. Switching mid-lease to actual expenses is not permitted.

Active-duty military members may still deduct moving-related mileage at the medical/moving rate when the move is due to a military order. That exception does not apply to civilian taxpayers.

How do you calculate the mileage deduction for 2026?

The formula is straightforward: deduction = business miles × applicable rate. The split-year structure adds one step — you need to separate your miles by date range before multiplying.

Step-by-step calculation with a split-year example

Suppose you drove 12,000 business miles in 2026: 5,000 between January and June, and 7,000 between July and December.

Jan 1–Jun 30: 5,000 miles × $0.725 = $3,625
Jul 1–Dec 31: 7,000 miles × $0.76 = $5,320
Total deduction: $3,625 + $5,320 = $8,945

If you had used a single annual rate, you would have gotten the math wrong. Your mileage log needs to show trip dates clearly so you can allocate miles to the correct period.

Where to report it:

Self-employed (sole proprietors, single-member LLCs): Line 9 of Schedule C (Form 1040), under “Car and truck expenses.” You’ll also complete Part IV of Schedule C or attach Form 4562 if required.
Partnerships and S-corps: Vehicle expenses flow through the entity return; partners and shareholders may need to report on their individual returns depending on reimbursement arrangements.
Employees: Form 2106 is largely unavailable for most employees under current law. The Form 2106 instructions cover the narrow categories (Armed Forces reservists, qualified performing artists, fee-basis state officials) that still qualify.

Note: parking fees and tolls are deductible on top of the standard mileage rate, whether you use standard mileage or actual expenses. Publication 463 confirms this — they are treated as separate deductible travel costs.

Pre-filing checklist:

Total business miles for Jan 1–Jun 30
Total business miles for Jul 1–Dec 31
Parking and toll receipts (deductible separately)
Mileage log with dates, destinations, and business purposes

Pro Tip: If your mileage app exports a single annual total, filter by date range before you calculate. A single blended number will give you the wrong deduction in a split-year.

Standard mileage rate vs. actual expenses: which is better for you?

The standard mileage rate wins on simplicity. The actual-expense method wins when your vehicle is expensive to operate. The right answer depends on your specific numbers, and the only way to know is to model both.

Standard mileage rate tends to favor you when:

Your vehicle has low operating costs (fuel-efficient, low maintenance)
You drive a high number of business miles (the per-mile rate adds up fast)
You want minimal recordkeeping
You use a leased vehicle

Actual-expense method tends to favor you when:

Your vehicle has high fuel, insurance, or repair costs
You have a newer, expensive vehicle with significant depreciation
Your business-use percentage is high and operating costs exceed the per-mile rate
You already track all vehicle expenses precisely

The actual-expense method covers gas, oil, tires, repairs, insurance, registration, depreciation (or lease payments), and garage rent — all multiplied by your business-use percentage.

Switching rules matter. If you use the standard mileage rate in the first year you place a vehicle in service for business, you can switch to actual expenses in a later year. But if you switch, the Form 2106 instructions require you to use straight-line depreciation for the vehicle’s remaining useful life. You cannot use accelerated depreciation or bonus depreciation after that switch. If you start with actual expenses and claim Section 179 or bonus depreciation in year one, you are locked into actual expenses for that vehicle permanently.

Pro Tip: Run both calculations before you file — not after. Collect your total vehicle operating costs for the year alongside your mileage log. The 15 minutes it takes to compare both methods can be worth hundreds of dollars.

For vehicles with high operating costs, managing your auto budget carefully throughout the year makes the actual-expense comparison much easier at tax time.

What records does the IRS require for a mileage deduction?

The IRS expects contemporaneous records — meaning you document each trip at or near the time it happens, not from memory at year-end. A log reconstructed in December from a vague calendar is a weak defense in an audit.

Topic No. 510 lays out the required fields. Every mileage log entry should capture:

Field	What to record
Date	Exact date of each business trip
Starting point	Address or location where the trip began
Destination	Address or location where the trip ended
Business purpose	Specific reason (client name, project, meeting type)
Odometer start	Beginning odometer reading
Odometer end	Ending odometer reading
Business miles	Total miles for that trip
Method	App, paper log, or GPS record

Retention: Keep mileage logs and supporting records for at least three years from the date you file the return (or two years from the date you paid the tax, whichever is later). If you underreport income by more than 25%, the IRS has six years to audit.

App vs. paper: Mileage tracking apps like MileIQ, Everlance, or TripLog auto-capture GPS data and generate reports you can export at tax time. Automated expense tracking reduces the risk of gaps in your log and makes the business-purpose field the only thing you need to fill in manually. Paper logs work fine — they just require more discipline.

The business purpose field is where most logs fall short. “Client meeting” is not enough. Write “meeting with [Client Name] re: Q3 contract renewal” or “delivery to [Project Site] for job #204.” Specific entries hold up; vague ones invite scrutiny.

How does employer reimbursement work under an accountable plan?

Employees cannot deduct unreimbursed mileage on their own returns under current law. The practical fix for small business owners with employees who drive for work: set up a formal accountable plan and reimburse at the IRS standard rate.

Accountable plan vs. nonaccountable plan:

Accountable plan: Reimbursements are tax-free to the employee and fully deductible to the business, provided employees submit contemporaneous mileage logs and return any excess reimbursement within a reasonable time.
Nonaccountable plan: Reimbursements are treated as taxable wages to the employee and subject to payroll taxes. The business still deducts them, but the employee pays income tax on the amount.

Reimbursing at or below the IRS standard mileage rate under an accountable plan keeps the payment off the employee’s W-2 entirely. Reimburse above the rate and the excess becomes taxable compensation. For payroll integration details on setting up compliant reimbursement workflows, this expense reimbursement guide covers the mechanics well.

Bookkeeping entry for a reimbursement: Debit “Vehicle Expense” (or “Employee Reimbursement”), credit “Cash/Bank.” Attach the employee’s mileage log to the transaction. In Xero, you can attach the log directly to the bill or expense claim so the documentation lives with the transaction permanently.

Pro Tip: Put your accountable plan in writing. A one-page policy document stating the reimbursement rate, submission deadline, and log requirements protects the business if the IRS questions whether the plan qualifies. Verbal policies don’t hold up.

What mileage mistakes trigger IRS audits?

Most mileage audits come down to the same handful of problems. Here’s what to watch for and how to fix each one before you file.

Vague business purpose entries. “Business” or “client meeting” with no specifics. Fix: add the client name, project number, or meeting topic to every entry.
Claiming commuting miles. Driving from home to your regular office is never deductible. Fix: your first and last trips of the day are commuting unless your home is your principal place of business.
No contemporaneous log. A year-end reconstruction from memory or a calendar. Fix: log trips within 24–48 hours using an app or a running spreadsheet.
Round-trip math errors. Doubling one-way distances without confirming the actual route. Fix: use GPS data or map the route and record actual miles.
Missing parking and toll receipts. These are deductible separately but require documentation. Fix: photograph receipts immediately or use a receipt-capture app.
Claiming 100% business use on a vehicle also used personally. The IRS scrutinizes this heavily. Fix: track personal miles separately and calculate an honest business-use percentage.

State tax rules add another layer. Some states conform to federal mileage deduction rules; others set their own rates or disallow the deduction entirely for state income tax purposes. California, for example, does not always conform to federal vehicle expense rules. Check your state’s rules separately — a deduction that works on your federal return may not carry over to your state return.

If the IRS contacts you about a mileage claim, produce your contemporaneous log, odometer records, and any corroborating evidence (calendar entries, client invoices, GPS data). A CP2000 notice is not an audit, but it requires a prompt, documented response. Having clean records from the start is the only reliable defense.

What most taxpayers get wrong about the mileage deduction

The standard mileage rate looks simple, and that simplicity is part of the problem. Because the math is easy, taxpayers often skip the step that actually matters: deciding whether the standard rate is even the right method for their situation.

A vehicle with high insurance, frequent repairs, or significant depreciation will almost always yield a larger deduction under the actual-expense method. The standard rate is calibrated to an average vehicle. If your vehicle is above average in operating cost, you are leaving money on the table every year you default to the standard rate without checking.

The other thing worth saying plainly: the deemed depreciation built into the standard rate is not free. Every mile you claim reduces your vehicle’s cost basis. When you sell the vehicle, that reduced basis increases your taxable gain. Taxpayers who drive 20,000+ business miles per year and then sell their vehicle are sometimes surprised by the gain calculation. The deduction was real, but so is the downstream consequence.

Finally, documentation is not a year-end task. The IRS standard for “contemporaneous” means at the time of the trip, not in April. A log built from memory has gaps, and gaps are what auditors look for. Build the habit of logging trips the same day, and the rest of the process takes care of itself.

FAQ

What is the IRS business mileage rate for 2026?

The IRS business standard mileage rate is 72.5 cents per mile for January 1 through June 30, 2026, and 76 cents per mile for July 1 through December 31, 2026. The mid-year increase was published in the official IRS Revenue Procedure/Notice.

How much can I write off for mileage in 2026?

Your deduction equals your total business miles multiplied by the applicable rate for each period. For example, 12,000 business miles split evenly across both periods yields a deduction calculated using the respective 2026 rates before adding parking and tolls.

Who is eligible to claim the mileage deduction in 2026?

Self-employed taxpayers and business owners are eligible; most W-2 employees are not, because the unreimbursed employee expense deduction remains suspended under current law. Employees should ask their employer to set up an accountable reimbursement plan instead.

How do you calculate mileage reimbursement for 2026?

Multiply the employee’s business miles by the applicable IRS rate for the period driven (72.5¢ or 76¢ per mile). Reimbursements at or below the IRS rate under a written accountable plan are tax-free to the employee and fully deductible to the business.

Can I switch between the standard mileage rate and actual expenses?

Yes, with conditions. If you use the standard mileage rate in the first year a vehicle is placed in service, you may switch to actual expenses in a later year, but you must then use straight-line depreciation for the vehicle’s remaining life. Starting with actual expenses and claiming Section 179 or bonus depreciation locks you into actual expenses permanently for that vehicle.
