The automotive industry is undergoing a significant transformation, with electric vehicles (EVs) leading the charge toward sustainable transportation. For U.S. businesses, this shift presents both opportunities and challenges, particularly in the realm of mileage reimbursement. As more employees opt for EVs, companies must adapt their reimbursement policies to ensure fairness and compliance.
Understanding Mileage Reimbursement
Mileage reimbursement is a common practice where employers compensate employees for the use of their personal vehicles for business purposes. This compensation typically covers fuel, maintenance, depreciation, and other associated costs. While traditional vehicles rely on gasoline, EVs operate on electricity, introducing different cost dynamics that necessitate a reevaluation of reimbursement methods.
IRS Standard Mileage Rates
The Internal Revenue Service (IRS) annually sets standard mileage rates to simplify the calculation of deductible vehicle expenses. As of January 1, 2025, the rates are:
- Business use: 70 cents per mile, up from 67 cents in 2024.
- Medical or moving purposes: 21 cents per mile.
- Charitable organizations: 14 cents per mile.
These rates apply uniformly to all vehicle types, including electric, hybrid, gasoline, and diesel-powered cars.

Calculating EV Mileage Reimbursement
Employers have two primary methods to reimburse EV mileage:
1. IRS Standard Rate
Using the standard rate simplifies the process, as it encompasses all vehicle-related expenses. For instance, an employee driving 1,000 business miles in 2025 would receive:
1,000 miles × $0.70/mile = $700
2. Actual Expense Method
Alternatively, employers can reimburse based on the actual expenses incurred. This method requires detailed tracking of costs such as electricity consumption, maintenance, insurance, and depreciation. While potentially more accurate for EVs, it demands meticulous record-keeping.
Factors Influencing EV Operating Costs
- Electricity Rates: Varying by region and time, electricity costs directly impact EV operating expenses.
- Vehicle Efficiency: Measured in miles per kilowatt-hour (kWh), efficiency varies among EV models.
- Charging Infrastructure: Access to home, workplace, or public charging stations can influence costs.
Comparing EV and Gasoline Vehicle Costs
Fuel vs. Electricity Expenses
EVs generally have lower fueling costs compared to gasoline vehicles. For example, if electricity costs $0.13 per kWh and an EV consumes 0.3 kWh per mile, the cost per mile is approximately $0.039. In contrast, a gasoline vehicle averaging 25 miles per gallon at $3.00 per gallon incurs a cost of $0.12 per mile.
Maintenance and Operational Differences
EVs typically require less maintenance due to fewer moving parts, no oil changes, and reduced brake wear. This can result in lower overall operating costs.
Employer Considerations for EV Reimbursement
To develop equitable reimbursement policies, employers should:
Â
- Assess Regional Electricity Costs: Recognize that electricity prices vary by location and may fluctuate over time.
- Account for Charging Variability: Consider differences between home charging (potentially lower costs) and public charging stations (which may be more expensive).
- Include EV-Specific Expenses: Factor in costs unique to EVs, such as battery degradation over time.

State-Specific Regulations and Incentives
While the IRS sets a standard mileage rate, some states offer additional incentives or have different regulations regarding electric vehicle reimbursement. Employers and employees should be aware of these variations to maximize their benefits.
States with EV-Specific Mileage Reimbursement Policies
Certain states provide additional tax credits or EV-friendly policies that can affect mileage reimbursement calculations. For example:
- California offers rebates for businesses that use EVs for commercial purposes.
- New York has incentives for companies switching to electric fleets.
- Colorado provides additional tax deductions for businesses using EVs.

Employers operating in these states may need to adjust their mileage reimbursement policies to reflect regional benefits.
Impact of Electricity Prices on Reimbursement
Electricity costs vary significantly from state to state. For example:
- Hawaii and California have some of the highest electricity rates, making EV operation more expensive.
- Washington and Idaho have lower electricity costs, reducing per-mile expenses.
Since the IRS mileage rate does not differentiate between gasoline and electric vehicles, businesses may need to consider regional energy costs when determining fair reimbursement policies.
Special Considerations for Public vs. Home Charging
Some states offer discounted electricity rates for EV owners charging at home, while public charging stations may have higher costs per kWh. Businesses might need to differentiate reimbursement policies based on whether employees charge at home or at commercial charging stations.
Challenges in EV Mileage Reimbursement
Despite the benefits, businesses face unique challenges when reimbursing EV drivers.
No Standardized EV-Specific Mileage Rate
Unlike gasoline vehicles, electric cars have different energy consumption rates based on battery size, charging efficiency, and driving conditions. The IRS standard mileage rate does not account for these variations, leading to potential over- or under-reimbursement for EV drivers.
Varying Electricity Costs
Electricity prices fluctuate by region and time of day, making it difficult to establish a universal reimbursement rate that accurately reflects EV operating costs.
Employer & Employee Fairness Concerns
Some employees may feel that gasoline car drivers are reimbursed too much while EV drivers receive less than their actual costs. Employers must ensure their policies are transparent and data-driven to maintain fairness.
To address these challenges, companies can consider:
- Offering custom EV reimbursement rates based on actual electricity costs
- Encouraging employees to track real-time charging expenses
- Providing incentives for home charging, where costs are generally lower
Conclusion
The rise of electric vehicles in the U.S. workforce presents new challenges and opportunities for mileage reimbursement policies. While the IRS sets a standard mileage rate, employers must consider electricity costs, charging infrastructure, and evolving regulations to ensure fair and accurate reimbursement.
By adopting data-driven policies, leveraging technology, and staying informed on state incentives, businesses can effectively navigate EV reimbursement challenges while optimizing costs and maintaining employee satisfaction.
