California Travel Reimbursement Law: Mileage, Deadlines, and Claims

California travel reimbursement law requires your employer to pay you back for every necessary cost you take on while traveling for work. The rule lives in Labor Code Section 2802, and it covers mileage on your own car, airfare, hotels, rideshares, tolls, parking, and reasonable meals on the road.¹ If your employer is pushing those costs onto you, the law is on your side.

Which Travel Costs Your Employer Has to Cover

Section 2802 requires reimbursement of all necessary expenses you incur as a direct result of doing your job. That obligation applies even when your employer didn’t specifically approve the spending in advance, as long as the cost was genuinely required for the work. A last-minute bus fare to make a client meeting counts.

The typical categories look like this:

Transportation: airfare, train and bus fares, rideshare costs, rental cars, and mileage on your personal vehicle.
Lodging: hotel or other accommodations when you need to stay overnight for work.
Tolls and parking: any fees you pay to park at a client site or use toll roads on a work route.
Meals and incidentals: reasonable food costs during business trips away from home.

The line that trips people up is the one between a commute and work travel. Driving from your home to the same office every day is a commute, and your employer owes you nothing for it. But travel between job sites during the workday, trips to meet clients at their locations, and travel to a temporary worksite farther from home than your normal office are all reimbursable. If your employer sends you to a site that takes longer to reach than your usual commute, the extra distance is on them.

Mileage on Your Personal Vehicle

When you drive your own car for work, your employer has to reimburse the full cost of operating it: fuel, wear and tear, insurance, and depreciation. Most employers use the IRS standard mileage rate as the benchmark, which is 72.5 cents per business mile for 2026.²

Employers can pay a different rate, but if they pay less than the IRS number, they carry the burden of proving that lower rate actually covers your full vehicle costs. That’s a hard case to make in California, where gas prices and insurance premiums run above the national average. Paying the IRS rate is the safe harbor. If you’re being reimbursed at, say, 50 cents per mile while driving in the Bay Area or Los Angeles, there’s a strong argument that rate doesn’t come close to covering what you’re actually spending.

Travel Time Is a Separate Question

Reimbursement covers your out-of-pocket money. Whether you also get paid wages for the hours you spend traveling is a different question, and the answer is often yes.

Travel between work sites during the workday is always compensable time under California law.³ Required out-of-town travel is too: when your employer sends you to another city for a conference, meeting, or event, the hours you spend getting there and back count as hours worked, including waiting time at airports or stations. Purely personal time on the trip, like sightseeing after a conference ends or sleeping at the hotel, doesn’t count.

If your employer temporarily assigns you to a worksite farther from your home than your regular office, the extra commute time beyond your usual commute is compensable.⁴ Normal commute of 20 minutes, temporary assignment 50 minutes away? Your employer owes you for the extra 30 minutes each way.

Receipts, Logs, and When You Get Paid

Employers can require reasonable documentation before processing reimbursements, such as receipts, mileage logs, or credit card statements. What they can’t do is set the bar so high that legitimate claims get blocked. If you lost a receipt but can show the expense through a bank statement or a calendar entry with the business purpose, a flat “no receipt, no reimbursement” rule won’t hold up.

Reimbursements should appear on the next regular paycheck after you submit a properly documented claim. Unreimbursed expenses aren’t classified as “wages” under California law, so the waiting-time penalties that apply to unpaid final wages don’t apply here.⁵ The amount still accrues interest from the date you originally spent the money, though, so delays cost your employer regardless.¹

Protect yourself by keeping a running log. Date, amount, business purpose, and any supporting documentation. A simple spreadsheet updated weekly is far more persuasive than reconstructing six months of expenses from memory. The IRS recommends holding on to expense records for at least three years, and up to four years for employment-related tax records.⁶

How Long You Have to File

You have three years from the date an expense goes unreimbursed to bring a claim under Section 2802. This comes from California’s general three-year deadline for claims based on a statutory violation. Some attorneys stretch the window to four years by adding a claim under California’s unfair competition law, which allows restitution over a longer period. Either way, don’t wait. Receipts disappear, memories blur, and the longer you sit on it the harder your case gets to prove.

Filing a Claim if Your Employer Won’t Pay

If your employer refuses to reimburse valid expenses, your first option is a wage claim with the Division of Labor Standards Enforcement, known as the Labor Commissioner’s office. You file an Initial Report or Claim form, which has a specific checkbox for business expense claims.⁷

The DLSE notifies both sides within 30 days and usually schedules a settlement conference first. If the case doesn’t settle, it moves to a formal hearing where testimony is taken under oath, and the Labor Commissioner issues a decision within 15 days after that hearing.⁸ Either side can appeal to civil court.

If you win, your award is the full unreimbursed amount plus interest running from the date you originally spent the money. Employees who go the lawsuit route instead of the DLSE can also recover attorney’s fees on top of the unreimbursed expenses. The statute defines “necessary expenditures” to include the reasonable legal costs of enforcing your rights, so your employer effectively pays for your lawyer if you prevail.¹ That’s what keeps smaller claims viable. Without it, the cost of a lawyer would make fighting over a few hundred dollars in gas money impractical.

Your Employer Can’t Punish You for Asking

California law prohibits your employer from firing, demoting, or otherwise punishing you for filing a reimbursement claim or complaining about unpaid expenses.⁹ The protection covers formal DLSE claims, informal complaints to a supervisor, and even verbal statements that you believe you’re owed money. You don’t have to file anything with the government first to be covered.

If your employer takes an adverse action against you within 90 days of a protected complaint, the law creates a rebuttable presumption that the action was retaliatory. The burden shifts to your employer to prove they had a legitimate, unrelated reason. Beyond reinstatement and back pay, an employer who retaliates faces a civil penalty of up to $10,000 per employee for each violation.⁹
