California Expense Reimbursement: What Labor Code §2802 Requires from Employers

California's expense reimbursement law is mandatory, and it extends beyond obvious costs like business travel. Under Labor Code §2802, private employers must reimburse employees for all necessary business expenses. Failure to comply can be costly: the original amount owed, 10% annual interest from the date each expense was incurred, and the employee's attorney's fees.

This article covers what the statute actually requires, which categories routinely generate claims, and what a defensible expense reimbursement policy looks like.

Key Takeaways

• §2802 applies to all California private employers, regardless of size. Public employers are exempt.

• No agreement can waive an employee's reimbursement rights. Any such provision is void by statute.

• A losing employer pays the original expense, plus 10% annual interest (accruing from the date of the expense), plus the employee's legal fees.

• Remote and hybrid work arrangements have expanded the categories of covered expenses well beyond travel. This includes internet, phone, and home office equipment, each of which may create reimbursement obligations depending on the facts.

• A single flawed policy applied across your workforce can create class action and PAGA exposure.

What §2802 Actually Says (And What Employers Miss)

California Labor Code §2802(a) states: 

"An employer shall indemnify his or her employee for all necessary expenditures or losses incurred by the employee in direct consequence of the discharge of his or her duties, or of his or her obedience to the directions of the employer, even though unlawful, unless the employee, at the time of obeying the directions, believed them to be unlawful."

Employers commonly misread three parts of this language:

• "Even though unlawful" - the statute covers expenses from following directions even if those directions later turn out to be unlawful. The employer cannot use its own wrongdoing to avoid reimbursement.

• "Necessary" is not strictly defined - courts apply it broadly. It generally means reasonably required to perform the job, not absolutely indispensable.

• §2802(c) defines "necessary expenditures" to include attorney's fees the employee incurs to enforce the statute. That fee-shifting provision is what makes it economically viable for an employee to litigate over a $200 phone bill.

All awards for reimbursement carry interest at the same rate as civil judgments, accruing from the date the employee incurred the expense. That rate is 10% per year.

The Expense Categories That Generate the Most Claims

The IRS standard mileage rate for 2026 is 72.5 cents per mile for business use, up 2.5 cents from 2025. The California DLSE has confirmed reimbursing at the IRS rate generally satisfies §2802 for vehicle expenses, absent contrary evidence.

What an Unreimbursed Expense Can Cost an Employer

The liability from a §2802 violation compounds in several directions:

• Direct recovery: The employee recovers the unreimbursed amount, plus 10% annual interest accruing from the date each expense was incurred, plus attorney's fees. If a claim takes a year to litigate, a $1,000 unreimbursed expense can cost far more once attorney's fees are added.

• DLSE citation: The Labor Commissioner may assess a civil penalty of $100 for a first violation and $250 per subsequent violation.

• Class action: A policy gap that applies to an entire job classification creates class-action exposure. See DefendMyBiz's class action defense practice.

• PAGA claims: A §2802 violation is a Labor Code violation, which can serve as the predicate for a PAGA representative action under §2698. That means civil penalties on behalf of all aggrieved employees.

• Retaliation claim: An employer cannot terminate an employee for requesting reimbursement. If an employer fires an employee for invoking rights under §2802, it may constitute illegal retaliation under California labor law. A termination connected to a reimbursement request adds a wrongful termination exposure on top of the wage claim.

What a Defensible Expense Reimbursement Policy Must Cover

A written expense reimbursement policy is your primary evidentiary tool if a claim is filed. Informal practice does not substitute for documentation before the DLSE or a court.

A compliant policy should address:

• Defined categories: Specify what qualifies (mileage, phone, internet, remote work costs, required tools/software) and what does not. Vague language like "business-related expenses" invites disputes.

• Mileage rate: Update it annually. For 2026, the IRS rate is 72.5 cents per mile.

• BYOD and phone stipend methodology: Document how the percentage was calculated. A flat rate without a stated basis is vulnerable.

• Remote and hybrid provisions: Identify which home office costs are covered, what percentage of internet and phone is reimbursable, and the submission process. If your policy hasn't been updated since 2020, it almost certainly has gaps.

• Submission timelines and receipt requirements: Set a clear deadline for expense claims. Consistency in enforcement protects you if a late claim is disputed.

• No-waiver compliance: Under §2802, employees cannot contract away reimbursement rights. Ensure your policy and any employment agreements don't inadvertently attempt to do so.

Annual review is not optional. Mileage rates, state law changes, and your actual work arrangements all change. A policy that accurately reflected your business in 2022 may create §2802 exposure today.

Conclusion

Expense reimbursement failures start with a policy that was never written, never updated, or never applied consistently. By the time an employee files a DLSE claim or serves a PAGA notice citing §2802, the pattern has usually been building for months. 

The employer who reimbursed mileage informally, never addressed the remote-work phone stipend, or assumed that a salary increase covered everything, has an exposure problem.
