The 2026 IRS business mileage rate is 72.5 cents per mile. The rate applies to qualified business use of a car, van, pickup, or panel truck and is commonly used by employers to calculate mileage reimbursement.
The IRS standard mileage rate gives employers a simple national benchmark for reimbursing business mileage. It can also be used by eligible self-employed taxpayers to calculate deductible business vehicle expenses.
| Use Case | 2026 IRS Rate | Change from 2025 |
|---|---|---|
| Business | 72.5¢/mile | +2.5¢ |
| Medical | 20.5¢/mile | -0.5¢ |
| Qualified Moving | 20.5¢/mile | -0.5¢ |
| Charitable | 14¢/mile | No change |
When does the 2026 IRS mileage rate take effect?
The 2026 IRS mileage rate takes effect on January 1, 2026. Employers using the federal mileage rate should update their reimbursement calculations, payroll documentation, reimbursement policies, and mileage-tracking workflows before the first reimbursement cycle that includes 2026 business miles.
IS the IRS Rate mandatory for employers?
No. The IRS standard mileage rate is optional. Employers may reimburse at the IRS rate, below the IRS rate, above the IRS rate, or use a different reimbursement method, such as FAVR or a taxable allowance. However, reimbursements must follow accountable plan rules to remain tax-free, and some states may require employers to reimburse necessary business expenses.
Policy reminder:
Some states and jurisdictions may require employers to reimburse necessary business expenses, including business use of a personal vehicle. Employers should review applicable state law before setting a reimbursement rate below the IRS rate.
What does the 2026 rate increase mean for employers?
The business mileage rate increased by 2.5 cents per mile from 2025. That may look small, but it adds up quickly for companies with high-mileage drivers.
Example cost impact
A company with 25 employees driving an average of 400 business miles per week, a 2.5-cent rate increase adds about $13,000 in annual reimbursement costs.

Can W-2 employees deduct mileage in 2026?
Most W-2 employees cannot deduct unreimbursed business mileage on their federal tax return. This makes employer reimbursement policy more important because employees generally cannot rely on a personal tax deduction to recover unreimbursed business driving costs.
Unreimbursed employee mileage
Most W-2 employees cannot deduct unreimbursed business mileage. If the company does not reimburse fairly, high-mileage employees may absorb business costs out of pocket.
Accountable reimbursement
Employers can reimburse documented business mileage tax-free when the reimbursement follows accountable plan rules and is supported by accurate mileage records.
When are mileage reimbursements tax-free?
Mileage reimbursements are generally not taxable to employees when they are paid under an accountable plan. The reimbursement should have a business connection, be substantiated with accurate mileage records, and require employees to return any excess amount when applicable.
Business connection
The mileage must be tied to work-related travel, not ordinary commuting or personal driving.
Substantiation
The employee should provide mileage records with dates, locations, business purpose, and miles driven.
Excess return
Amounts paid above substantiated expenses should be returned or treated as taxable wages.
IRS mileage rate vs. FAVR: which is better?
The IRS mileage rate is simple, but it is a national average. It does not automatically adjust for each employee’s location, mileage band, vehicle cost, insurance rate, or operating conditions. FAVR can be more precise because it separates fixed ownership costs from variable driving costs.
| Program | How it works | Strength | Potential drawback |
|---|---|---|---|
| IRS mileage rate | Pays one cents-per-mile rate | Simple and familiar | May overpay low-cost/low-mileage drivers and underpay others |
| FAVR | Separates fixed and variable costs | More precise, often tax-free when compliant | Requires more program design and administration |
| Car allowance | Pays a flat monthly amount | Easy for payroll | Usually taxable and often disconnected from actual business use |
Not sure which model fits your workforce: Compare your current reimbursement approach against driver mileage, location, and vehicle costs before choosing a rate.
The importance of accurate mileage tracking
An accurate mileage log is essential for substantiating business mileage and supporting tax-free reimbursement. A defensible log should document the date of each trip, the business purpose, the starting and ending locations, and the total business miles driven.
