California Mileage Reimbursement Law
California mileage guide covering Labor Code §2802, lawful reimbursement methods, and required expense documentation.
Short answer
Yes. California Labor Code §2802 mandates that employers indemnify employees for all necessary expenditures or losses incurred in direct consequence of their duties. Under California Supreme Court precedent (Gattuso v. Harte-Hanks), employers must reimburse vehicle expenses using one of three lawful methods: Actual Expense, Lump Sum/Allowance, or the Mileage Rate method (often benchmarked to the IRS rate).
At a glance
- California Labor Code §2802 is an affirmative legal mandate — private employers cannot waive or contract around it.
- Under Gattuso v. Harte-Hanks Shoppers, Inc. (2007), employers have 3 lawful reimbursement methods: Actual Expenses, Mileage Rate, or Lump Sum / Car Allowance.
- If using the IRS standard rate (72.5¢ Jan-Jun / 76¢ Jul-Dec 2026), the employee can still challenge it if actual vehicle costs exceed the rate.
- Commuting between home and the regular workplace is not reimbursable; all job-related travel between worksites or client locations is mandatory.
California Labor Code §2802 & Gattuso v. Harte-Hanks
California has the nation's strictest employee expense reimbursement protections. Labor Code §2802(a) requires employers to indemnify employees for all necessary expenditures incurred in direct discharge of duties. Any contract or agreement waiving this right is null and void under Labor Code §2804.
In the landmark ruling Gattuso v. Harte-Hanks Shoppers, Inc. (2007) 42 Cal.4th 554, the California Supreme Court established three legally permissible methods for vehicle expense reimbursement:
| Reimbursement Method | How It Works | Legal Requirements & Considerations |
|---|---|---|
| 1. Mileage Rate Method | Employer pays a set cents-per-mile rate for substantiated business miles (frequently the IRS rate). | Rebuttable presumption: If the employee proves actual costs were higher, the employer must pay the difference. |
| 2. Actual Expense Method | Employee tracks and submits detailed records of all vehicle expenses (fuel, insurance, repairs, depreciation) multiplied by business %. | Most accurate but administratively burdensome; requires extensive receipt and odometer log tracking. |
| 3. Lump-Sum / Car Allowance | Employer pays a fixed periodic amount (e.g., $400/month) or increased salary/commission. | Must be separately identified and objectively calculated to cover all actual expenses; cannot dilute minimum wage. |
Three lawful vehicle expense reimbursement methods under California Supreme Court precedent (Gattuso v. Harte-Hanks).
Is the IRS Mileage Rate Mandatory in California?
The IRS standard mileage rate is not strictly required by California statute, but it is widely used as a safe-harbor benchmark. When an employer reimburses at the IRS rate (72.5¢ for Jan-Jun and 76¢ for Jul-Dec 2026), California courts treat this as presumptively reasonable.
However, if an employee drives an expensive-to-operate vehicle required by the employer or operates in high-cost areas where fuel, maintenance, and insurance exceed the IRS rate, the employee retains the right under §2802 to submit actual expenses and claim the difference.
Required California Mileage Claim Documentation
- Detailed trip log with date, origin, destination, and business purpose.

Common questions
Can California employers pay less than the IRS mileage rate?
Yes, but only if the lower rate fully covers all actual expenses incurred by the employee (gas, maintenance, insurance, depreciation). If the lower rate results in an underpayment, the employer violates California Labor Code §2802.
Can an employee waive mileage reimbursement in California?
No. Under California Labor Code §2804, any agreement by an employee to waive their right to expense reimbursement under §2802 is completely void and unenforceable as against public policy.
Are tolls and parking included in California mileage reimbursement?
No. Bridge tolls, highway tolls, and parking fees incurred for business purposes must be reimbursed separately on top of any per-mile vehicle reimbursement.
