When employees use personal vehicles for business purposes, employers often reimburse mileage using the IRS standard mileage rate or an internal company rate. For calendar year 2026, the IRS business standard mileage rate is $0.725 per mile. Medical and qualified moving travel for eligible military and intelligence-community taxpayers use $0.205 per mile, while charitable mileage remains $0.14 per mile.
This calculator computes reimbursement from miles driven and the selected rate. It also lets you compare standard-rate reimbursement with a custom employer rate or a simple operating-cost estimate. Use it as a planning and policy worksheet, not as a substitute for your employer's reimbursement policy or tax advice.
Mileage documentation still matters. To keep reimbursements non-taxable under an accountable plan, employers generally need a contemporaneous log showing date, destination, business purpose, and miles driven.
Mileage reimbursement looks simple, but policy differences, custom company rates, and recordkeeping rules create confusion. This worksheet helps employees estimate reimbursements and lets employers sanity-check travel submissions against a defined rate schedule.
Reimbursement = Miles Driven × Rate per MileResult: $362.50 reimbursement
500 business miles × $0.725 per mile = $362.50. At this rate over a full year of 1,000 miles per month, the annual reimbursement would be $8,700.
The IRS standard mileage rate is meant to approximate the variable and fixed cost of operating a vehicle for qualified business travel. Employers often use it as a reimbursement benchmark because it is simple to administer and widely recognized.
The IRS expects contemporaneous documentation for mileage deductions and accountable-plan reimbursements. A compliant log includes the travel date, starting and ending locations, business purpose, and total miles. Digital mileage apps can simplify the process, but a manual log works if it is accurate and timely.
Federal law does not require private employers to reimburse business mileage in every case, but some states do require reimbursement of necessary business expenses. That means an internal policy can be less important than state labor-law requirements for employers operating in reimbursement-mandate states.

For calendar year 2026, the IRS standard mileage rate is $0.725 per mile for business use, $0.205 per mile for medical or qualified moving travel, and $0.14 per mile for charitable service.
Mileage reimbursement at or below the IRS standard rate is not taxable to the employee when submitted under an accountable plan (with dates, mileage, and business purpose). Reimbursements exceeding the IRS rate are taxable as income for the excess amount.
Self-employed individuals can generally deduct eligible business mileage. Most employees cannot claim unreimbursed employee mileage on their federal return under the current post-TCJA rule set, although certain specialized taxpayers and some state returns still follow different rules.
Business mileage includes travel between work locations, to client meetings, to temporary work sites, and for other business purposes. Your regular commute from home to your main office is NOT business mileage. Trips from home for business events outside your normal pattern may qualify.
The standard mileage rate is simpler and works well for most drivers. Actual expense tracking may yield a larger deduction if you drive an expensive vehicle with high costs. You must choose one method for the tax year; you cannot mix and match.
You do not need gas or maintenance receipts when using the standard mileage rate. You do need a mileage log showing date, destination, business purpose, and miles driven. This log must be maintained contemporaneously, not reconstructed later.
