Mileage Tax Deduction Calculator
Quick answer: For 2026, the IRS standard mileage rate is 72.5 cents per mile for business miles driven January 1–June 30, and 76 cents per mile for miles driven July 1–December 31. Medical and moving miles use 20.5 cents (Jan–Jun) and 23.5 cents (Jul–Dec); charity miles use 14 cents all year. Multiply your miles in each period by the matching rate, then add parking and tolls — the calculator below does this automatically. Figures here are estimates only, not tax advice.

How to use this calculator
Split your 2026 mileage log at June 30 / July 1, because the two halves of the year use different IRS rates. Enter business, medical/moving, and charity miles for each half, then add any business parking and tolls — they are deductible in full on top of the mileage amount.
Keep a mileage log with the date, miles driven, destination, and business purpose for every trip. If you are ever audited, that log is the evidence behind the deduction.
How it works
The standard mileage method multiplies your logged miles by the IRS rate in effect when the miles were driven. Parking fees and tolls attributable to business travel are added at 100% of what you paid. The rate applies to gasoline, diesel, hybrid, and electric vehicles alike. This calculator does not compute the actual-expense method, does not handle mixed personal/business use allocations, and is an estimate only — not tax advice.
Worked example
You drive 6,000 business miles January–June 2026: 6,000 × $0.725 = $4,350.00. You drive 2,000 business miles July–December 2026: 2,000 × $0.76 = $1,520.00. You also pay $45 in business tolls. Estimated total deduction: $4,350.00 + $1,520.00 + $45.00 = $5,915.00.

Frequently asked questions
Which mileage rate applies if I drive miles in both halves of 2026?
The rate in effect on the date you drive the miles. Use 72.5 cents per business mile for January 1–June 30, 2026 and 76 cents for July 1–December 31, 2026 (medical and moving miles use 20.5 and 23.5 cents respectively; charity miles use 14 cents all year). The calculator above keeps the two periods separate so each gets the right rate.
Can employees deduct unreimbursed business mileage?
No, not on a federal return: the Tax Cuts and Jobs Act suspended the deduction for unreimbursed employee expenses — including business mileage — for tax years 2018 through 2025, and it remains suspended in 2026. Self-employed people, freelancers, and independent contractors can still deduct qualifying business mileage on Schedule C. This page gives estimates only and is not tax advice.
Does the standard mileage rate apply to electric vehicles?
Yes. The IRS standard mileage rate applies equally to gasoline, diesel, hybrid, and electric vehicles — there is no separate EV rate.
Are there limits on using the standard mileage rate?
Yes. You generally cannot use it if you operate five or more cars in the same business at once (a fleet), claim Section 179 or depreciation on the car, or used the actual-expense method for the car in a prior year under certain conditions. Commuting from home to a regular workplace is never deductible, regardless of the method.
