2026 mileage reimbursement calculator and rates by state

Mileage reimbursement pays employees back for using their personal vehicles for business travel, and 2026 has two different rates to track. The IRS business rate is 72.5 cents per mile through June 30 and 76 cents per mile from July 1 onward.

Getting the rate right matters for both compliance and cost. This guide covers the current 2026 rates, how to calculate reimbursement across the split year, federal and state rules, and the best practices that keep your policy audit-ready.

What is mileage reimbursement?

Mileage reimbursement is a payment made to employees who use their personal vehicles for business travel. It covers costs such as fuel, maintenance, insurance, depreciation, and wear and tear, but it doesn't apply to commuting between home and your regular workplace.

Unlike wages, mileage reimbursement repays business expenses, so it isn't taxable for employees when handled correctly. Employers can generally deduct it as a business expense.

Here's how to think about what qualifies:

• Business driving: Travel to client sites, off-site meetings, between work locations, or to transport materials and equipment
• Not covered: Regular commuting to and from home and your primary workplace

The federal government doesn't require employers to reimburse mileage, but some states do. The IRS publishes a standard rate each year to simplify compliance and reflect current vehicle operating costs.

2026 IRS mileage rates and the mid-year increase

For 2026, the IRS business standard mileage rate is 72.5 cents per mile from January 1 to June 30 and 76 cents per mile from July 1 to December 31, following the IRS's mid-year rate increase in Announcement 2026-11, which modified Notice 2026-10.

The IRS raised the standard mileage rates for the second half of 2026 to offset rising fuel costs, and it's the first midyear adjustment since 2022. If your employees drove for business in both halves of the year, you'll need to apply each rate to the miles driven in its period.

Business mileage rate

The business rate is 72.5 cents per mile from January 1 to June 30, rising to 76 cents per mile from July 1 to December 31, 2026. This is the most commonly used rate and covers all typical vehicle operating costs, including fuel, maintenance, insurance, registration, and depreciation.

Medical and moving mileage rate

The medical and moving rate is 20.5 cents per mile in the first half of 2026, rising to 23.5 cents per mile from July 1. The medical portion applies to driving for qualified medical care, while the moving portion applies only to active-duty military members relocating under orders.

Charitable mileage rate

The charitable rate is 14 cents per mile. Unlike the other rates, this one is set by statute and doesn't change annually with vehicle operating costs.

Mileage reimbursement rates by year

The IRS adjusts the business and medical rates each year to reflect changing fuel prices, insurance costs, and vehicle depreciation. Looking at historical rates can help you spot trends and plan for future policy updates. These figures come from the IRS's annual standard mileage rate notices for 2025, 2024, and 2023:

The year 2026 is unusual because the IRS split the year with a midyear increase, its first since 2022, rather than setting a single annual rate.

How to calculate mileage reimbursement

To calculate mileage reimbursement, multiply the number of business miles driven by the reimbursement rate.

Reimbursement amount = Business miles driven * Mileage rate

For example, if you drove 100 miles for business and your company reimburses at the first-half 2026 IRS rate of 72.5 cents per mile:

Mileage reimbursement = 100 miles * $0.725 = $72.50

Because 2026 has two business rates, you apply each rate to the miles driven in its period. Use 72.5 cents for trips before July 1 and 76 cents for trips on or after July 1. A driver with miles in both halves splits the calculation: 100 business miles in June come to 100 * $0.725 = $72.50, while 100 business miles in August come to 100 * $0.76 = $76.00.

Some employers use the IRS standard rate, while others set a custom rate based on local fuel prices or company policy. Just remember that anything above the IRS rate becomes taxable income for the employee.

Federal mileage reimbursement rules

There's no federal law requiring employers to reimburse mileage, but the IRS sets clear rules for keeping reimbursements tax-free. The key concept is the difference between an accountable plan and a non-accountable plan. The former keeps payments tax-free, while the latter treats them as wages.

Accountable plan requirements

An accountable plan is an IRS-approved reimbursement structure that excludes payments from an employee's taxable income. To qualify, your plan must meet three requirements:

• Business connection: The expense must be a legitimate business expense incurred while performing work duties
• Adequate accounting: Employees must substantiate expenses with records like mileage logs that include date, destination, and business purpose
• Return of excess: Employees must return any reimbursement that exceeds substantiated expenses within a reasonable time

Meeting all three requirements ensures your reimbursement plan remains IRS-compliant and keeps mileage payments tax-free for employees.

Documentation and recordkeeping

The IRS expects mileage logs to be maintained contemporaneously, meaning employees should record trips as they happen rather than reconstructing them later. Each entry should include:

• Date of the trip
• Starting location and destination
• Business purpose
• Total miles driven
• Odometer readings (recommended for accuracy)

Digital tracking apps and mileage tracking software make this easier by capturing trip details automatically through GPS.

Excluded commuting miles

Daily commuting to and from home and a regular workplace is never reimbursable, even if you stop for work-related errands along the way. The IRS treats commuting as a personal expense, not a business one.

There are exceptions. Driving from home to a temporary work location, like a client site you'll visit for less than a year, generally qualifies as business mileage. The same applies if you're traveling between two work locations during the day.

Is mileage reimbursement taxable?

Mileage reimbursement isn't taxable when it's paid at or below the IRS rate under an accountable plan. If your reimbursement structure doesn't meet IRS requirements, the payments become taxable wages subject to income and payroll taxes.

Tax-free reimbursements under an accountable plan

When you reimburse employees at or below the IRS rate and require proper documentation, the payments are excluded from taxable income. They don't appear on the employee's W-2, and you don't owe payroll taxes on them.

To stay tax-free, your plan must meet all three accountable plan requirements: business connection, adequate accounting, and return of excess reimbursements.

Taxable reimbursements under a non-accountable plan

Reimbursements become taxable when your plan doesn't meet accountable plan rules. Common examples include flat monthly car allowances with no mileage tracking, payments above the IRS rate, or reimbursements without supporting documentation.

In these cases, the IRS treats the payment as wages. You must report it on the employee's W-2 and withhold income and payroll taxes.

The Tax Cuts and Jobs Act suspended employee deductions for unreimbursed business expenses through 2025, and the One Big Beautiful Bill Act (OBBBA) made the suspension permanent, with limited exceptions for groups like Armed Forces reservists, certain performing artists, and fee-basis government officials. A compliant reimbursement policy keeps employees from absorbing business costs out of pocket.

Standard mileage rate vs. actual expense method

The IRS gives you two methods for calculating vehicle expense deductions: the standard mileage rate or the actual expense method. Each has its place depending on how much you drive and how detailed you want to get with recordkeeping.

The standard rate is simpler. Just multiply your business miles by the current IRS rate. The actual expense method tracks every real cost, which can yield a bigger deduction if your vehicle is expensive to operate, but it requires meticulous recordkeeping.

State mileage reimbursement requirements

While there's no federal mandate, several states require employers to reimburse necessary business expenses, including mileage for personal vehicle use. Failing to comply with state law can lead to wage claims and penalties.

Most states without a specific statute default to the IRS standard rate as the practical benchmark. A handful of states and the District of Columbia require reimbursement of necessary business expenses, which often means at least the IRS rate, but the specifics vary by jurisdiction. Finance teams managing multi-state workforces may find it useful to review their broader expense management and procurement processes alongside their mileage policies to keep everything consistent.

If you have employees in any of these jurisdictions, make sure your policy reflects state law and check with your state labor authority for current requirements.

Best practices for mileage reimbursement tracking

Accurate mileage tracking protects your company from compliance issues and ensures employees get paid fairly and on time. The right combination of process and technology makes the difference between a clean audit and a scramble through filing cabinets. Make sure your tracker applies the correct split-year 2026 rate to each trip.

Use a mileage tracking app

GPS-based mileage tracking apps automatically log trips, calculate distances, and apply the current reimbursement rate. They eliminate the guesswork that comes with manual logs and reduce the chance of errors that could trigger an audit.

Log trips immediately

The IRS prefers contemporaneous records, which are logs created at the time of the trip rather than reconstructed weeks later. Recording trips as they happen captures accurate odometer readings and details while they're fresh.

Separate business and personal miles

Mixing personal and business miles is one of the fastest ways to lose a deduction during an audit. Make it clear in your policy that employees must distinguish between the two and only submit business miles for reimbursement.

Keep digital records

Storing mileage logs digitally makes them easy to retrieve during audits or tax season. Cloud-based expense platforms keep records timestamped, organized, and accessible without paper files or scattered spreadsheets. Finance teams that have already moved to AI-powered accounting software often find that digital mileage records slot naturally into their existing automated workflows.

Automate expense reporting

Automated expense reporting reduces manual data entry errors and speeds up the reimbursement process. When employees can submit mileage through a mobile app and managers can approve it in a few clicks, payments happen faster and finance teams spend less time chasing paperwork.
