California Cell Phone Reimbursement Law: Rules, Amounts, and Claims

Under California’s cell phone reimbursement law, your employer must pay you back a reasonable percentage of your personal cell phone bill when you use the phone for work. That obligation, set by Labor Code 2802, applies even if you have an unlimited plan and your bill never went up because of work use. If your employer refuses, you can recover the reimbursement, interest running back to when you first incurred the expense, and your attorney’s fees.¹

What Labor Code 2802 Covers

Labor Code 2802 requires employers to cover all necessary expenses an employee incurs as a direct result of doing the job.¹ The statute exists to stop companies from pushing their operating costs onto workers. When your job requires you to make calls, send texts, use work apps, or check email on your personal phone, the cost of that usage is a business expense the company has to share.

The unlimited-plan question was settled in Cochran v. Schwan’s Home Service, Inc., where the California Court of Appeal held that an employer must reimburse a reasonable percentage of an employee’s cell phone bill regardless of whether the employee has an unlimited plan.² The logic is simple: the employer is getting the benefit of that phone line for its business, so it has to bear a fair share of the cost. The fact that your bill would have been identical without work use doesn’t matter.

When You’re Entitled to Reimbursement

The trigger is whether you are required to use your personal device for work. Clear examples: your employer tells you to install a work email app on your phone, use your personal device for multi-factor authentication into company systems, or clock in and out through a timekeeping app with no alternative. In each case, the expense is almost certainly “necessary” under the statute.

The requirement doesn’t have to be written down. If your manager regularly expects you to answer calls or respond to messages on your personal phone and no company-issued device is available, the practical reality is that your phone use is work-related. Voluntary use is different. If your employer offers a company phone and you just prefer your own, the argument for reimbursement weakens. The question is always whether business need drove the use.

Home Internet and Other Remote Work Costs

Section 2802 isn’t limited to phone bills. If you work remotely and need home internet to do your job, a reasonable portion of that cost falls under the same statute, and the same Cochran logic applies: your employer is using that connection for its business, even if you already had it before you started working from home.¹ Printer supplies, computer equipment, and required software subscriptions are commonly reimbursable for remote workers too.

How the Reimbursement Amount Is Set

The standard is a “reasonable percentage” of your bill for business use. The law doesn’t prescribe a formula, so employers have some room as long as the result fairly reflects the work-related share.

A flat monthly stipend is the most common approach. Many employers pay a fixed amount each month as an estimated reimbursement. For it to hold up, the stipend has to be a good-faith approximation of actual costs. Five dollars a month for an employee who is on the phone for work hours a day won’t cut it. On the other end, an employer doesn’t have to cover the entire bill when work use is only a small share of total usage.

Some employers instead ask for phone bills and try to identify the work-related portion by reviewing call logs, data usage by work apps, or the percentage of the billing cycle spent on business tasks. It’s more precise but takes more effort on both sides, and it raises obvious privacy issues. The Cochran court specifically noted that the reasonable-percentage approach avoids employers digging into the private financial lives of their workers.²

Is the Reimbursement Taxable?

Handled correctly, no. The IRS treats the business use of a cell phone as a tax-free working condition fringe benefit when the phone is used primarily for legitimate business reasons rather than as a perk.³ Incidental personal use of a phone provided or reimbursed for business purposes still qualifies as a tax-free de minimis fringe benefit.

To keep the payment tax-free, the employer’s plan has to qualify as an “accountable plan” under federal tax rules. Three things must be true: the reimbursement has a clear connection to a business expense, the employee substantiates the expense (without burdensome call-by-call logs), and any excess is returned.⁴ The IRS eliminated the heavy recordkeeping requirements that used to apply to cell phones, so employers don’t need to demand detailed usage logs.⁵

If the plan doesn’t meet those requirements, the reimbursement is treated as taxable wages: it lands on your W-2, and both you and your employer owe payroll taxes on it. Most well-structured stipend programs avoid this, but an unexplained lump sum added to your paycheck may be taxable.

How to Ask Your Employer for Payment

Start with your employee handbook. Many California employers already have a reimbursement policy because the legal risk of ignoring 2802 is well known. If a policy exists, follow it. That’s the fastest way to get paid.

If there’s no policy or your employer hasn’t been paying, send a written request to your supervisor or HR. Keep it short and professional: state that you use your personal cell phone for work duties and are requesting reimbursement under Labor Code 2802. Specify the time period.

Attach copies of your phone bills for the relevant months. You don’t need to hand over every personal call detail, but showing the billing period and the total monthly cost gives your employer what it needs to calculate a reasonable percentage. If you can point to specific work-related usage, like the volume of business calls or data used by work apps, include that summary. Make it easy to say yes.

Keep copies of everything you send and every response you get. If this escalates to a formal claim, that paper trail is your evidence.

Filing a Wage Claim if Your Employer Refuses

If your employer ignores your request or refuses to pay, you can file a wage claim with the California Labor Commissioner’s Office (the Division of Labor Standards Enforcement).⁶ Unpaid expense reimbursements are handled the same as unpaid wages in this process.

You can file online, by mail, or in person at a local Labor Commissioner office. The office investigates and typically schedules a settlement conference between you and your employer. Most disputes resolve there. If yours doesn’t, the case moves to a hearing where a hearing officer reviews the evidence and issues a decision.⁶

What You Can Recover

The remedies go beyond the reimbursement itself. An award carries interest at the standard rate for civil judgments, and that interest accrues from the date you originally incurred the expense, not from the date you filed the claim.¹ For reimbursements an employer has skipped for years, the interest alone can add up.

The statute also defines “necessary expenditures” to include attorney’s fees you spend enforcing your rights under the section.¹ That’s a real lever. An employer that forces you to hire a lawyer to recover a few hundred dollars in phone reimbursements can end up paying thousands in legal fees. This is why many of these claims settle quickly.

Employees can also pursue reimbursement failures through the Private Attorneys General Act (PAGA), which lets workers bring claims on behalf of themselves and coworkers for Labor Code violations. Under the reformed PAGA rules that apply to notices filed after June 19, 2024, failure to reimburse business expenses is a curable violation, meaning the employer gets a chance to fix it. If the employer was already taking reasonable steps to comply before receiving a PAGA notice, the maximum penalty drops to 15% of the amount originally sought; if it starts complying within 60 days of the notice, the cap is 30%.⁷ PAGA penalties are split 65% to the state and 35% to affected employees.

Your Employer Can’t Retaliate

Under Labor Code 98.6, your employer cannot fire you, demote you, cut your hours, or take any other adverse action against you for requesting reimbursement or filing a claim with the Labor Commissioner. Retaliation creates a separate legal claim with its own penalties. The point of the protection is that you shouldn’t have to weigh keeping your job against enforcing a right the statute already gives you.

Deadline to File

You have three years to file a claim for unpaid expense reimbursements. The California Code of Civil Procedure sets a three-year limitations period for claims based on a statutory obligation like Labor Code 2802.⁸ The clock runs from the date you incurred each expense. If your employer has been skipping reimbursements for five years, you can recover the most recent three years but not the earlier two. The longer you wait, the more falls outside the window.
