Under California Labor Code Section 2802, your employer must reimburse you for every necessary business expense you pay out of pocket to do your job. That covers mileage, required tools, uniforms, training fees, supplies, and a reasonable share of your cell phone and home internet bills when work requires them. The duty is automatic: once the employer knows or should know you spent the money, it owes you back without waiting for you to fill out a form.1California Legislative Information. California Code LAB 2802
Section 2802(a) also covers losses you incur while following your employer’s directions, even if those directions turn out to be unlawful. The one carve-out is when you knew at the time that what you were being asked to do was unlawful.1California Legislative Information. California Code LAB 2802
What Counts as a Necessary Business Expense
The statute does not list categories. Any cost that is “necessary” to perform your duties qualifies. In day-to-day practice, that usually means:
- Mileage when you drive your personal vehicle for work trips (your regular commute does not count). Many employers reimburse at the IRS standard mileage rate, which is 72.5 cents per mile for 2026.2Internal Revenue Service. Standard Mileage Rates Updated for 2026
- Tools, safety gear, and software you buy because the job requires them.
- Uniforms the employer requires that you cannot reasonably wear as everyday clothing.
- Training, licensing, certification, and continuing education fees your employer directs you to complete.
- Office supplies, postage, printing, and similar materials.
The IRS mileage figure is not legally mandated under Section 2802. It is a widely used proxy for the real cost of operating a vehicle. An employer can pay less if the lower rate still reflects your actual expenses, but underpaid mileage is one of the most common sources of 2802 disputes.
Cell Phone, Internet, and Home Office Costs
Remote and hybrid work has made this the busiest area under Section 2802. In Cochran v. Schwan’s Home Service, Inc., the California Court of Appeal held that an employer must reimburse a reasonable percentage of an employee’s personal cell phone bill whenever the phone is required for work. The court held this applies even when the employee has an unlimited plan and would have paid the same amount with or without work use.3Justia. Cochran v Schwans Home Service
The same reasoning extends to home internet, electricity, and other utilities that go up when you work from home. No statute sets a fixed percentage. Many employers pay a flat monthly stipend in the range of $50 to $100, though the legally safer approach is one that reasonably approximates your actual work-related share of each bill.
Why Your Reimbursement Might Show Up as Taxable Wages
Whether a reimbursement is tax-free depends on how your employer structures the plan. The IRS splits these into accountable and nonaccountable plans, and the difference lands on your W-2.
Accountable Plans
An accountable plan keeps reimbursements off your taxable wages. Three conditions have to be met: the expense has a business connection, you substantiate it with receipts or similar documentation, and you return any excess payment to the employer.4Internal Revenue Service. Publication 15-B Employers Tax Guide to Fringe Benefits
IRS safe-harbor guidelines generally give employees 60 days to substantiate an expense. Submit later than that and the reimbursement can be reclassified as taxable income, with federal and state income tax, Social Security, and Medicare withheld from a future paycheck.
Nonaccountable Plans
If your employer pays a flat allowance with no receipt requirement and no obligation to return excess, the IRS treats it as a nonaccountable plan. Those payments become taxable wages subject to federal income tax withholding, Social Security, Medicare, and FUTA.5Internal Revenue Service. Publication 15 (2026) Circular E Employers Tax Guide A flat $200-a-month “expense allowance” with no strings attached is taxable income. A properly run accountable plan is not.
Document Everything
The employer’s duty to reimburse does not depend on perfect paperwork, but good records are what move a request from “disputed” to “paid.”
- For mileage, keep a log with the date, start and end points, and business purpose of each trip. A tracking app on your phone handles this with no effort.
- For purchases, save receipts (a photo stored in a cloud folder is fine).
- For phone and internet, keep monthly statements and note your estimated share of work use, along with how you arrived at the estimate.
Submit promptly. The 60-day IRS window matters even when the employer is willing to pay, because late submissions can get swept into taxable wages.
How to Ask and What to Do If You’re Ignored
Start with your employer’s internal process, whether that is an expense portal, a form, or an email to your manager. Keep copies of everything you send. If there is no formal process, put the request in writing and describe the expense, attach documentation, and ask when payment will arrive. That written record proves the employer knew about the expense, which matters later. Most employers pay within one to two pay cycles, often as a separate non-taxable line on your paycheck.
When an employer ignores the request, you don’t need a lawyer to escalate. The California Division of Labor Standards Enforcement (DLSE) accepts wage claims that include unpaid expense reimbursement. You can file online, by email, by mail, or in person at any Labor Commissioner’s Office. There is no filing fee.6California Division of Labor Standards Enforcement. How to File a Wage Claim
After you file, the office investigates and typically schedules a settlement conference. If that doesn’t resolve things, a hearing officer reviews the evidence and issues a decision.6California Division of Labor Standards Enforcement. How to File a Wage Claim
What You Can Recover
Section 2802 is structured to make these claims worth bringing. Section 2802(b) adds interest at the civil judgment rate on any award, running from the date you originally spent the money, not the date you filed the claim.1California Legislative Information. California Code LAB 2802
Section 2802(c) defines “necessary expenditures or losses” to include all reasonable costs of enforcing your rights under the statute, including attorney’s fees. That fee-shifting provision is what makes individual reimbursement cases viable. A lawyer can take the case knowing the employer pays the legal bill if you win.1California Legislative Information. California Code LAB 2802 Interest plus fee exposure is what drives most employers to settle valid claims before a hearing, and awards that reach judgment often exceed the original expense by a substantial margin.
How Long You Have to File
You have three years from the date you incurred an unreimbursed expense to bring a Section 2802 claim. The deadline comes from California Code of Civil Procedure Section 338(a), which governs liabilities created by statute.7California Legislative Information. California Code CCP 338 In some situations, a claim brought under California’s Unfair Competition Law stretches that window to four years.
The clock runs separately for each expense. If your employer has shorted your mileage every month for five years, you can still recover the past three years’ worth, but older expenses keep dropping off the back end. The deadline doesn’t pause while you remain employed, so there’s no reason to wait until you leave.
Who Isn’t Covered
Section 2802 protects employees across every California industry and job title, in the office, on a job site, or at home. It does not cover independent contractors. If your employer has classified you as a contractor, you would first have to establish that you were actually an employee (California’s ABC test under AB 5 governs most of those disputes) before the reimbursement obligation applies.1California Legislative Information.
