Mileage Reimbursement Calculator
Enter your miles driven for business, medical, and charity purposes to get your total IRS mileage reimbursement or tax deduction. The IRS raised the 2026 business rate mid-year, so the calculator defaults to the 76 cents per mile rate that applies from July 1, 2026 and keeps 72.5 cents for trips taken January 1 through June 30. You can also switch to any year back to 2020, enter a custom employer rate, or add a round-trip count. Results update instantly, and a full breakdown panel shows every line of the math.
How the IRS mileage reimbursement rate works
The IRS publishes a standard mileage rate each year (and sometimes mid-year) that taxpayers and employers can use instead of tracking every actual vehicle expense. For 2026 there are two business rates: 72.5 cents per mile for trips taken January 1 through June 30, and 76 cents per mile from July 1 onward after the IRS revised the rate in Announcement 2026-11. To calculate your reimbursement, simply multiply the miles driven by the applicable rate: 500 business miles x $0.76 = $380.00. Three categories exist: business (the highest rate), medical/moving (for active-duty military only after 2017), and charity (a lower, congressionally fixed rate of 14 cents). You cannot mix actual expenses and the standard rate for the same vehicle in the same year.
What qualifies as deductible or reimbursable mileage
Business miles include driving to client meetings, between multiple work locations, to pick up supplies, or any trip that is ordinary and necessary for your trade or business. Commuting from your home to your main workplace is never deductible, no matter the distance. Medical miles cover trips to a doctor, hospital, or other medical facility for yourself or a qualifying dependent; the round-trip distance counts. Charity miles are those driven while volunteering for a qualified 501(c)(3) organization on behalf of that organization, not personal travel to a volunteer event. Self-employed taxpayers deduct business miles on Schedule C or Schedule F; employees lost the unreimbursed employee expense deduction from 2018 through 2025 under the Tax Cuts and Jobs Act.
Keeping a valid mileage log
The IRS requires a contemporaneous mileage log for any mileage claim. Each entry should include the date, the origin and destination (address or at least city), the business purpose of the trip, and the odometer reading at the start and end. "Contemporaneous" means recorded at or near the time of the trip, not reconstructed months later from memory. Paper logs, spreadsheets, and smartphone apps such as Everlance, MileIQ, and Stride all satisfy this requirement. In an audit, the burden of proof is on the taxpayer, and estimates without supporting records are routinely disallowed.
Standard mileage rate vs. actual expense method
Instead of the per-mile standard rate, you may deduct your actual vehicle costs: gas, oil, tires, repairs, insurance, registration fees, and depreciation, prorated by the percentage of business use. This can produce a larger deduction for heavy drivers in expensive vehicles, but it requires detailed receipt tracking all year. You must choose one method per vehicle for the first year you use it for business. If you choose the standard mileage rate in year one, you can switch to actual expenses in later years; the reverse is not always allowed. For most employees and small-business owners, the standard rate is simpler and competitive. Run both calculations the first year to see which is better for your situation.

Official IRS standard mileage rates for each period. The IRS revised the 2026 rates mid-year in Announcement 2026-11, so trips before and after July 1, 2026 use different rates. The charity rate has been fixed at 14 cents by statute since 1998. The active-duty military moving rate equals the medical rate.
Frequently asked questions
What is the IRS mileage rate for 2026?
The 2026 business rate changed mid-year. Notice 2026-10 set it at 72.5 cents per mile from January 1, and Announcement 2026-11 raised it to 76 cents per mile for miles driven on or after July 1, 2026. The medical and military-moving rate follows the same split: 20.5 cents through June 30 and 23.5 cents from July 1. The charity rate stays at 14 cents per mile all year.
Is employer mileage reimbursement taxable income?
Reimbursements paid at or below the IRS standard rate under an accountable plan are not taxable income to the employee and are not subject to FICA. An accountable plan requires a business connection, adequate accounting (a mileage log with business purpose), and the return of any excess advance. If your employer pays more than the IRS rate, the excess is taxable wages. Reimbursements under a non-accountable plan are always taxable regardless of rate.
Can I deduct mileage as a W-2 employee?
Generally no. The Tax Cuts and Jobs Act of 2017 suspended the miscellaneous itemized deduction for unreimbursed employee business expenses through 2025. For most W-2 employees, the only path to a mileage deduction is to have your employer reimburse you under an accountable plan. Certain job categories (Armed Forces reservists, fee-basis government officials, qualified performing artists, and educators for supply expenses) retain limited deductions; check IRS Publication 463 for specifics.
Does the mileage rate cover gas, or is it in addition to gas costs?
The standard mileage rate is an all-in rate. It is designed to cover gas, oil, maintenance, tires, insurance, registration, and the depreciation component of the vehicle. You cannot claim the standard mileage rate and then separately deduct fuel costs for the same miles. The only additional costs you can deduct alongside the standard rate are parking fees, tolls, and any interest on a car loan (for self-employed taxpayers).
What is the difference between the business and medical mileage rates?
The business rate is set by the IRS based on fixed and variable vehicle operating costs and is significantly higher (76 cents from July 1, 2026) than the medical rate (23.5 cents from July 1, 2026). The medical rate is calculated using only the variable portion of vehicle costs. To deduct medical mileage, you must itemize deductions on Schedule A, and your total unreimbursed medical expenses must exceed 7.5% of your adjusted gross income.
Can I use a different rate if my employer pays more or less than the IRS rate?
Yes. Employers are free to reimburse at any rate they choose. If they pay less than the IRS rate under an accountable plan, the difference is generally not deductible for W-2 employees (through 2025). Self-employed taxpayers can always claim up to the IRS standard rate on their return. This calculator includes a "Custom rate" option so you can enter your employer's actual per-mile rate.
Does the 2022 rate change affect my tax return?
Yes, and 2026 works the same way. 2022 had two different rates. The IRS raised the business rate mid-year: 58.5 cents per mile for trips taken January 1 through June 30, and 62.5 cents per mile for trips from July 1 through December 31. If you drove business miles in both halves of 2022, you need to calculate the two periods separately and add them together. This calculator has both 2022 half-year options, and both 2026 half-year options, in the period selector.
