Do You Have to Pay Employees for Using Their Own Phone to Punch In? BYOD Reimbursement Rules (2026)
Do You Have to Pay Employees for Using Their Own Phone to Punch In? BYOD Reimbursement Rules (2026)
The short answer: If you require an employee to use their personal phone to do their job, a handful of states require you to reimburse a reasonable share of what that phone costs them. California is explicit about it, and the amount is owed even when the employee pays nothing extra. Federal law has no reimbursement statute, but it does have a rule that stops you from pushing business costs onto a worker's wages. The cleanest way to close the exposure is not a stipend spreadsheet. It is to stop requiring the personal phone at all. Punch ships a shared iPad kiosk with a PIN on every plan, so a crew can punch in without anyone touching their own device.
Ninety-one percent of US adults own a smartphone, according to Pew Research Center survey data collected in 2025. That number is why so many small employers assume a phone-based time app is free infrastructure. It is not always free, and the bill does not arrive from the app.
Federal Law Has No Reimbursement Statute. It Has Something Else.
The Fair Labor Standards Act does not require an employer to reimburse business expenses. What it does have is 29 CFR 531.35, the "free and clear" rule.
Wages are not treated as paid unless they are paid finally and unconditionally. If an employee kicks back part of that wage to the employer, directly or indirectly, the wage requirement is not met. The regulation applies the idea to equipment: if the employer requires the employee to provide tools of the trade used in or specifically required for the employer's work, there is a violation in any workweek where the cost of those tools cuts into the minimum wage or the overtime premium.
The practical reading is narrow but real. A required phone is arguably a tool of the trade. For a worker earning well above minimum wage, the cost of a phone plan rarely drives them below the floor. For a crew paid at or near minimum wage, the math gets closer than owners expect, and the DOL measures by the workweek, not the year.
Federal law sets the floor. The states set the actual obligation.
The States That Require Reimbursement
Reimbursement law is a patchwork, and it is worth knowing which bucket you are in before you write a policy.
Broad affirmative statutes. California, Illinois, Montana, North Dakota, South Dakota, and New Hampshire have general statutes requiring reimbursement of necessary business expenses. These are the states where a required-phone policy is most likely to create a real obligation.
Narrow or conditional regimes. Massachusetts addresses transportation. Iowa governs the timing of authorized expenses. The District of Columbia covers tools and uniforms. Seattle has a local ordinance. Pennsylvania treats reimbursement as a matter of agreement rather than a standing requirement.
Everywhere else. Most states have no reimbursement statute and fall back to the federal minimum wage floor above.
If you run crews across state lines, satisfy the strictest state you operate in and apply it everywhere. Running two policies is how a payroll mistake becomes a class-wide one.
California: Reimbursement Is Owed Even If the Employee Pays Nothing Extra
Labor Code section 2802 requires an employer to indemnify an employee for all necessary expenditures incurred in direct consequence of the discharge of their duties. The case that made this concrete for phones is Cochran v. Schwan's Home Service, Inc. (2014) 228 Cal.App.4th 1137.
The employer's argument was the one every owner reaches for first. The employee has an unlimited plan. The work calls cost nothing incremental. Therefore nothing is owed.
The Court of Appeal rejected it. The holding: whether the employee has a plan with unlimited minutes or limited minutes, the reimbursement owed is a reasonable percentage of their cell phone bill. Partial reimbursement is always required when the personal phone is a job requirement. The California Supreme Court denied review, leaving the rule in place.
What courts and agencies have not supplied is a formula. "Reasonable percentage" is left to the employer's judgment, which is why practitioners writing about this generally report California employers landing on a flat stipend of roughly twenty-five to forty dollars a month. That is common practice, not a safe harbor.
The uncertainty is the actual cost. You are choosing an amount, documenting why, and hoping a plaintiff's lawyer agrees with your reasoning years later.
Illinois: The Requirement Comes With a Clock
Illinois amended the Wage Payment and Collection Act to add 820 ILCS 115/9.5. An employer must reimburse an employee for all necessary expenditures or losses incurred within the scope of employment and directly related to services performed for the employer. Necessary expenditures are defined as reasonable expenditures required in the discharge of employment duties that inure to the primary benefit of the employer.
Two mechanics matter more than the general rule.
The employee has 30 calendar days after incurring the expense to submit it with appropriate supporting documentation, unless the employer's written policy allows more time. And the employer is not liable under the section unless it authorized or required the employee to incur the expenditure, or it failed to comply with its own written expense reimbursement policy.
Read that second clause carefully. Your own written policy becomes enforceable against you. A policy you never follow is worse than a policy you never wrote. That is the same lesson as a timekeeping policy you do not enforce.
Note also what "primary benefit of the employer" invites. An employer can argue the employee would carry that phone anyway. Illinois has not settled it the way California did.
The Structural Fix: Stop Requiring the Personal Device
Every path above assumes the same premise, that punching in requires the employee's own phone. Change the premise and most of the analysis stops applying. If the personal phone is genuinely optional because you provide a working alternative at the job site, you are not requiring an employee to furnish a tool of the trade.
That is a policy decision, not a legal opinion, and it is worth making with your own counsel. But the operational version is simple: give the crew somewhere else to punch.
Punch is built for exactly this. Kiosk mode turns a shared iPad at the shop, in the trailer, or by the back door into a punch station. An employee taps their name in the picker, enters a PIN, and punches in. No personal phone, no personal account on the device, no company data on a worker's handset. Sessions end on log out or after a short idle window, so the iPad returns to the picker for the next person. Owners pair the iPad once with a code they can view or regenerate from Settings, and turning kiosk mode off revokes the org's paired devices. There is more on that setup in our shared iPad time clock guide.
Punches also work from any browser, so a shop computer is a valid punch surface for crew who work near one.
Employees who prefer their own phone still can. The point is that they are choosing to, not required to. That distinction is the whole ballgame.
What This Setup Gives You Beyond the Reimbursement Question
Removing the phone requirement solves a legal exposure. The rest of Punch solves the payroll problem underneath it.
Punch in, punch out, and lunch are tracked separately, so unpaid meal time never quietly inflates a paid total. Punches work offline, which matters in a basement, a parking structure, or a rural site where signal drops. The punch records locally and syncs when service returns, so nobody writes hours on a clipboard and nobody's data plan is doing the heavy lifting. Our guide to tracking hours without cell service covers that in depth.
Overtime is applied automatically against your fixed workweek, using overtime presets for more than 50 countries including state daily overtime rules where they apply. Weekly and bi-weekly pay periods are both supported, and split shifts stay split instead of merging into one long block. Owners and managers approve the week in one place with bulk approve and reject, so the hours that reach payroll are hours a human signed off on. Reports export to Excel or a QuickBooks CSV, or push straight into QuickBooks Online. Square is supported as well, and time off requests live in the same app.
On privacy, Punch verifies a punch with a job-site geofence on iOS, never a camera in your crew's face. There is no facial recognition and no photo at a punch, on a personal phone or a shared iPad. That matters more than it sounds when the device belongs to the employee, because a work app that photographs a worker on their own handset is a consent conversation you do not want to have.
Pricing is flat per organization. Every feature is on every plan, kiosk mode included, owners are always free, and nothing is billed per seat. Adding a seasonal crew for six weeks does not move your bill, and the feature that closes your reimbursement exposure is not sitting behind an upgrade.
The Bottom Line
Federal law will not hand you a reimbursement bill unless the cost cuts into minimum wage or overtime premium pay. Six states will. California requires a reasonable percentage of the phone bill even when the employee's plan already covers the use, and nobody can tell you exactly what percentage is safe. Illinois will enforce your own written policy against you, on a 30-day clock.
You can pay a stipend and document your reasoning. Or you can put a punch station where the crew already stands, keep the personal phone optional, and take the question off the table.
Start with Punch and give your crew somewhere to punch that is not their own pocket.
