California Labor Code Section 2802(a) is one of the most important reimbursement rules for employers with mobile employees. If employees use personal vehicles for work, your mileage reimbursement, car allowance, or vehicle reimbursement policy must be structured carefully enough to cover necessary business vehicle expenses.
Quick answer: California Labor Code Section 2802(a) requires employers to reimburse employees for necessary expenses incurred while performing job duties. For employees who use a personal vehicle for work, that can include fuel, insurance, maintenance, depreciation, registration, and other vehicle-related costs. Employers may use mileage reimbursement, actual expense reimbursement, or a lump-sum vehicle allowance, but the reimbursement must be sufficient to cover necessary business vehicle expenses.
What does California Labor Code 2802 require?
Under California Labor Code Section 2802(a), employers must fully reimburse employees for all expenses necessarily incurred as part of their job. If your organization has California employees who drive personal vehicles for work purposes, it is important to understand what constitutes an expense.
Expenses covered by section 2802
When an employee uses a personal vehicle to perform job duties, vehicle expenses are covered under section 2802. This includes depreciation, insurance, fuel, maintenance, and more. If an employee can show that your organization has failed to adequately reimburse them, it will prove a costly mistake.
Reimbursement methods for CA employees
In Gattuso v. Harte-Hanks Shoppers, Inc., the California Supreme Court recognized three ways employers may reimburse employees for work-required automobile expenses under Labor Code Section 2802:
- Actual expense reimbursement: The employee tracks vehicle expenses, and the employer reimburses the business-use portion.
- Mileage reimbursement: The employee tracks business mileage, and the employer reimburses at a cents-per-mile rate, such as the IRS mileage rate.
- Lump-sum reimbursement: The employer pays a fixed amount, such as a car allowance, as long as the amount is sufficient to cover necessary business vehicle expenses.
The key issue is not which method the employer uses. The key issue is whether the method fully reimburses the employee for necessary expenses.
When car allowances violate the CA Labor Code
Organizations that pay car allowances to California employees are using the lump-sum method. This method can create the greatest compliance risk if the allowance is taxable, not tied to business use, or insufficient to cover the employee’s actual business vehicle costs.
Because lump-sum payments do not require proof of business mileage, the IRS treats these as taxable income. This means a car allowance must cover all vehicle costs after taxes. In a high-cost state like California, the after-tax allowance amount must still be enough to cover the employee’s necessary business vehicle expenses.
When mileage reimbursements violate section 2802(a)
If an organization instead reimburses mileage, violations may still occur. This is for two reasons.
Fixed vehicle costs
First, employees accrue mileage at different rates. Every driver starts with a set of fixed costs (e.g., insurance, taxes, registration, depreciation) and must drive a certain number of miles for the reimbursement to cover those expenses, as well as travel-related costs (e.g., gas, oil, maintenance). Low-mileage drivers and even some mid-mileage drivers might not hit the break-even amount. Thus, an organization can be compliant with section 2802(a) for some employees but not others.
National mileage rate
For 2026, the IRS business mileage rate is 72.5 cents per mile. The IRS rate is based on a national study of fixed and variable vehicle costs, including depreciation, insurance, repairs, tires, maintenance, fuel, and oil. While the IRS rate is a useful benchmark, California employers should still evaluate whether it fully covers the actual costs incurred by their employees.
Where FAVR Fits Under California Reimbursement Rules
A Fixed and Variable Rate reimbursement program, or FAVR, can help employers build a more accurate vehicle reimbursement policy. Instead of paying every driver the same flat amount or the same cents-per-mile rate, FAVR separates fixed costs, such as insurance and depreciation, from variable costs, such as fuel and maintenance.
For California employers, this can be especially useful because vehicle costs vary by driver, location, and mileage level. A properly structured FAVR program can help employers improve reimbursement accuracy, reduce tax waste, and create stronger documentation for their vehicle reimbursement policy.
Evaluating your business vehicle program's compliance
Consider the following reasons why a travel reimbursement policy might fall short of California Labor Code 2802(a):
-
Your mileage reimbursement rate is arbitrary.
Many employers set a mileage rate that they assume will cover all expenses and then hire employees at that rate. However, an employer that arbitrarily sets the reimbursement rate faces a danger: an employee may later pursue a legal claim that the established rate does not accurately reflect actual expenses.
Low-mileage drivers, in particular, tend to be shorted on mileage reimbursements. This is because fixed costs like depreciation and auto insurance must be spread over a certain number of miles before the mileage reimbursement rate fully covers them, in addition to mileage-based costs like fuel, oil, and tires.
-
You compensate using a flat auto allowance.
A flat car allowance often fails to address the ever-changing expenses of a mobile employee. It may not keep up with gas prices, may not reflect the territory sizes of all employees, and may not adequately address depreciation, which increases with inflation. As cars increasingly serve as employees' offices, car allowances must be flexible enough to keep pace with increased travel and expenses.
Even worse, a car allowance is treated as taxable compensation by the IRS. So that $600 allowance becomes $390, and that $700 allowance becomes $455. (This assumes a total withholding of 35% for state and federal taxes, including FICA/Medicare.)
-
The IRS standard rate can prove insufficient.
Many employers use the IRS mileage rate because it is simple, familiar, and based on an annual study of vehicle operating costs. The Division of Labor Standards Enforcement has stated that the IRS mileage rate will generally satisfy the employer’s obligation, absent evidence to the contrary.
However, that last phrase matters. If an employee presents evidence that the IRS rate does not cover their actual necessary expenses, the employer may still be responsible for the difference. This risk may be higher for California employees in high-cost areas or for drivers whose mileage patterns do not align with national averages.
California Mileage Reimbursement Compliance Checklist
Use these questions to evaluate your current vehicle reimbursement policy:
- Do California employees use personal vehicles for work?
- Does the policy clearly define reimbursable business driving?
- Are employees required to track business mileage?
- Does the reimbursement account for fuel, maintenance, insurance, depreciation, registration, and tires?
- Are low-mileage drivers receiving enough to cover fixed vehicle costs?
- Are reimbursements taxable or non-taxable?
- Is the policy reviewed when IRS rates, fuel prices, insurance costs, or employee territories change?
- Can the company document how the reimbursement amount was calculated?
The costs of non-compliance with CA Labor Code 2802(a)
If an employee can demonstrate that the auto allowance, the IRS mileage rate, or the chosen mileage reimbursement rate does not cover expenses, the employer must pay the difference.
Furthermore, an employee can demand three years of back pay for unreimbursed expenses. Accrued interest as well as attorney's fees incurred from claims, as well as actions to enforce section 2802, are recoverable and may be awarded by either the courts or the Labor Commissioner.
If your organization is paying a flat taxable auto allowance, an arbitrary mileage reimbursement rate, or even the IRS rate for California employees, it is time to review your policy.
Review Your California Vehicle Reimbursement Policy
If your organization reimburses California employees through a flat car allowance, an arbitrary mileage rate, or the IRS mileage rate, now is the time to review your policy. mBurse can help you evaluate your current vehicle reimbursement program, compare reimbursement methods, and determine whether a tax-free FAVR reimbursement plan would better support your California employees.
FAQs About California Labor Code 2802(a) and Mileage Reimbursement
What does California Labor Code 2802(a) require?
California Labor Code 2802(a) requires employers to reimburse employees for necessary expenses incurred while performing their job duties. For mobile employees, this can include costs tied to using a personal vehicle for work, such as fuel, maintenance, insurance, depreciation, registration, and tires.
Does California require mileage reimbursement?
California requires employers to reimburse necessary business expenses, which may include vehicle expenses. Mileage reimbursement is a common method, but employers may also use actual-expense reimbursement or a lump-sum reimbursement if it fully covers the employee’s necessary costs.
Is the IRS mileage rate enough for California employees?
The IRS mileage rate is commonly used as a benchmark, but it may not always be enough for every California employee. If an employee can show that their actual business vehicle expenses exceed the reimbursement provided, the employer may be responsible for the difference.
Can a car allowance comply with California Labor Code 2802(a)?
A car allowance may comply if it fully reimburses the employee for necessary business vehicle expenses. However, a taxable or insufficient allowance can create compliance risk, especially if the employee’s after-tax amount does not cover actual vehicle costs.
What vehicle expenses may need to be reimbursed in California?
Vehicle expenses may include fuel, maintenance, repairs, tires, insurance, registration, depreciation, and other costs associated with the business use of a personal vehicle. Employers should evaluate both fixed costs and variable costs when reviewing reimbursement policies.
Why can mileage reimbursement fall short in California?
Mileage reimbursement can fall short when employees drive fewer business miles, because fixed costs like insurance, registration, and depreciation are spread across fewer miles. It can also fall short when California vehicle costs exceed the national averages used in standardized mileage rates.
How can employers reduce California reimbursement compliance risk?
Employers can reduce risk by tracking business mileage, reviewing actual vehicle costs, documenting how reimbursement amounts are calculated, and regularly updating policies when costs change. A structured reimbursement method, such as FAVR, may help account for mileage, location, fixed costs, and variable costs.
