The 2026 IRS Mileage Rate Increase: What It Means for Your Business
The 2026 IRS business mileage rate is 72.5 cents per mile, which makes CPM budgets worth reviewing for high-mileage teams.

The IRS set the 2026 business standard mileage rate at 72.5 cents per mile. Companies using CPM should review whether that national average still matches their driver mileage, geography, and reimbursement budget.
Key takeaways
- The 2026 business standard mileage rate is 72.5 cents per mile.
- High-mileage CPM populations can become expensive because fixed costs are paid through every mile.
- FAVR may be worth evaluating when drivers are high-mileage, distributed, and eligible.
The Internal Revenue Service recently announced that the standard mileage rate for business use of a vehicle in 2026 has increased to 72.5 cents per mile, up 2.5 cents from the previous year [1]. While this might seem like a minor adjustment, for companies managing a mobile workforce, it represents a significant shift in the economics of vehicle reimbursement.
If your company relies on a Cents-Per-Mile (CPM) reimbursement program, this rate increase will have an immediate and measurable impact on your bottom line. But more importantly, it highlights the fundamental flaws of relying on a single national average to reimburse your employees.
Here is what the 2026 rate increase means for your business, and why it might be time to rethink your reimbursement strategy.
Why Did the Rate Increase?
The IRS calculates the standard mileage rate based on an annual study of the fixed and variable costs of operating an automobile. The increase to 72.5 cents per mile reflects several macroeconomic trends affecting drivers in 2026:
- Rising Fuel Costs: Global energy market fluctuations and increased demand have pushed the variable cost of fuel higher.
- Elevated Vehicle Prices: The capital cost of purchasing new and used vehicles remains high, directly impacting the depreciation calculations used by the IRS.
- Insurance Premiums: Commercial and personal auto insurance rates have seen rapid increases due to higher repair costs and claim severities.
The IRS rate is designed to be a safe harbor-a maximum threshold up to which employers can reimburse employees tax-free without requiring detailed expense substantiation.
The Problem with the National Average
While reimbursing at 72.5 cents per mile is simple and IRS-compliant, it is rarely accurate. The IRS rate is a national average, meaning it attempts to blend the cost of driving a pickup truck in rural Texas with the cost of driving a hybrid sedan in downtown Los Angeles.
This creates two major problems for businesses:
1. Over-Reimbursing High-Mileage Drivers
The IRS rate heavily weights fixed costs (like depreciation and insurance) into its per-mile calculation. If an employee drives a high number of miles (e.g., 20,000 miles per year), they are receiving 72.5 cents for every one of those miles. However, their fixed costs do not increase linearly with mileage. Once their insurance and depreciation are covered, the company is effectively overpaying them for every additional mile driven. At 20,000 miles, the company is paying $14,500 annually-far more than the actual cost to own and operate a standard vehicle.
2. Geographic Inequity
Because the rate is national, it ignores local economic realities. An employee in a state with low gas taxes and cheap insurance might profit from the 72.5-cent rate. Conversely, an employee in a high-cost coastal city might find that 72.5 cents barely covers their localized fuel and insurance premiums. This inequity can lead to employee dissatisfaction and retention issues in expensive markets.
The FAVR Alternative
The 2026 rate increase is a perfect catalyst for finance leaders to evaluate a Fixed and Variable Rate (FAVR) program.
Instead of paying a flat 72.5 cents for every mile, a FAVR program separates the reimbursement into two components:
- A Fixed Payment that covers the localized cost of insurance, depreciation, and registration in the employee's specific zip code.
- A Variable Rate (usually much lower than the IRS standard rate, often between 15 and 25 cents per mile) that covers the localized cost of fuel and maintenance.
This structure eliminates the over-reimbursement of high-mileage drivers because the fixed costs are paid as a flat monthly sum, not multiplied by every mile driven. It also ensures geographic fairness, as rates are tailored to the exact cost of living where the employee operates.
Taking Action in 2026
If your organization has simply been updating your payroll system to match the new IRS rate every January, you are likely leaving money on the table while failing to reimburse your team accurately.
The increase to 72.5 cents per mile should serve as a wake-up call. By transitioning to a geographically precise, AI-driven FAVR program like Kliks, you can gain control over your vehicle reimbursement budget, ensure tax-free compliance, and treat every employee fairly, regardless of where they drive.
