Illinois Cell Phone Reimbursement Law: Policy, Penalties, and Deadlines

The Illinois cell phone reimbursement law is Section 9.5 of the Illinois Wage Payment and Collection Act, effective January 1, 2019. It requires employers to reimburse employees for the work-related portion of personal cell phone costs, along with any other necessary expense the employee incurs within the scope of employment that primarily benefits the employer. There is no dollar figure written into the statute. What the law does supply, in generous detail, is a penalty structure that compounds monthly until the employer pays.

What Counts as a Reimbursable Cell Phone Expense

Section 9.5 covers “necessary expenditures,” meaning any reasonable cost required to carry out job duties. Cell phone charges for work calls, emails, data use, and app access fall inside that definition when the employer expects or requires the use.

The reimbursable amount is the business-use portion of the bill, not the whole plan. If personal and business use share the same phone, the reimbursement should reflect the share that goes to work. One practical method is to track usage across three or four months to establish a reliable percentage and apply that percentage going forward. Agree on the calculation method in advance to head off disputes.

Illinois Administrative Code Section 300.540 provides a five-factor test for whether an expense primarily benefits the employer:

Whether the employee reasonably expected reimbursement.
Whether the expense was required to perform the job.
Whether the employer is receiving something it would otherwise have to pay for.
How long the employer benefits from the expense.
Whether the expense is a condition of the job.

No single factor controls. The analysis looks at the overall picture.¹ An employee who takes a handful of personal calls plus one work call a month has a weak claim. An employee who fields client calls, checks work email, and uses company apps on a personal phone daily has a strong one.

The law applies to employees, not independent contractors. A worker who is free from the employer’s control over how the work is performed, works outside the employer’s usual business, and is engaged in an independently established trade falls outside the IWPCA.

Flat Stipend or Actual-Cost Reimbursement

The statute does not prescribe a method. Employers have two practical options.

Actual-cost reimbursement tracks the statute most closely. The employee submits phone bills, the employer calculates the business-use share, and the employer pays that amount. The paperwork burden is real, especially at scale.

A flat monthly stipend is simpler. Typical stipends across industries run $30 to $60 per month depending on the role and expected usage. The legal risk is that the stipend must reasonably approximate actual costs. Section 9.5 explicitly prohibits “de minimis reimbursement,” so a policy that pays zero or a token amount will not survive challenge.² A $10 stipend for a sales representative on the phone with clients all day would almost certainly fail.

Whichever method you pick, put it in a written policy and apply it consistently across similar roles.

Why a Written Policy Is the Main Defense

A written reimbursement policy is not technically required, but it is the single most valuable tool an employer has. Section 9.5 says an employee is not entitled to reimbursement if the employer has an established written policy and the employee failed to follow it.² Without a written policy, that defense is unavailable.

A workable policy covers eligible expenses (cell service, data overages, work-related app subscriptions), the reimbursement method (actual cost, stipend, or hybrid), the submission deadline, required documentation, and the approval process.

Employees have their own deadline. They must submit requests with supporting documentation within 30 calendar days of incurring the expense, though a written policy can extend that window.² When receipts are lost, a signed statement describing the expense can substitute. Employers who never tell employees about the 30-day window often cannot enforce it later, so putting it in writing matters both ways.

One trap: if an employer’s written policy sets guidelines but the employer routinely pays above those guidelines in practice, the employer becomes liable for the higher amounts. The administrative code makes this explicit — custom and practice can override written limits.¹

Recordkeeping

Employers must keep reimbursement records for at least three years, including the policy itself, every employee request, approval or denial documentation, and records of payments with supporting documents.³ If a dispute reaches the Illinois Department of Labor, these records are the employer’s primary evidence.

When an Employer Is Not Liable

Section 9.5 builds in several protections for employers acting reasonably.

The written policy defense, above, is the strongest. An employee who did not follow an established written policy forfeits the right to reimbursement for that expense.

Authorization matters too. An employer is not liable unless it authorized or required the employee to incur the expense, or failed to follow its own reimbursement policy. If an employee unilaterally buys a premium phone plan and submits it for reimbursement, the employer can push back on the portion it never authorized.

A written policy can set specifications or spending caps, and the employer is not liable for the portion of any expense that exceeds those guidelines, provided the cap is not zero or a token figure.²

Company-issued phones change the analysis. If the employer provides a work phone, the case for reimbursing personal phone costs weakens considerably, because the employer is already supplying the tool.

Employers are not responsible for losses caused by the employee’s own negligence, normal wear, or theft, unless the theft resulted from the employer’s negligence. A cracked screen from a drop at home is not the employer’s problem.

What Non-Compliance Costs

Section 14 of the IWPCA layers several penalties that compound over time.

Damages, Fees, and Daily Penalties

An employee who is not paid on time can recover the unpaid amount plus damages equal to 5% of the underpayment for each month it remains unpaid, with no cap.⁴ In a civil action, the employee can also recover reasonable attorney fees and court costs on top of the underpayment and damages.

If the Illinois Department of Labor issues a demand or order to pay, the employer owes an administrative fee to IDOL regardless of outcome: $500 when the amount owed is $3,000 or less, $750 when it falls between $3,000 and $10,000, and $1,250 at $10,000 or more.⁴

An employer that fails to comply with IDOL’s demand or final order within the required timeframe faces further penalties: 1% of the underpayment per day payable to the employee, plus 20% of the underpayment payable to IDOL. The daily penalty is uncapped.⁵ A $1,000 reimbursement ignored for a few months can grow into a multi-thousand-dollar liability once monthly damages, administrative fees, and daily penalties stack up.

Criminal Liability

Willfully refusing to pay when able to do so is criminal. If the unpaid amount is $5,000 or less, it is a Class B misdemeanor. Above $5,000, a Class A misdemeanor. A repeat violation within two years of a prior conviction is a Class 4 felony.⁴

Employee Filing Deadline

Employees must file a complaint with IDOL within one year after the wages or expense reimbursement was due. Missing that window forfeits the administrative claim, though civil action deadlines may differ.

Federal Minimum Wage Overlay

Even employers who believe the IWPCA does not apply need to look at federal law. Under the Fair Labor Standards Act, when unreimbursed business expenses effectively push take-home pay below the federal minimum of $7.25 per hour or Illinois’s $15.00 per hour minimum, the employer has a wage violation.⁶⁷ The Department of Labor treats tools and expenses required by the employer as costs that cannot cut into the minimum wage floor in any workweek. A personal cell phone required for work falls squarely into that category.

There is an upside for employers who reimburse properly. The FLSA allows reimbursements that reasonably approximate actual business expenses to be excluded from the employee’s regular rate of pay for overtime calculations. Cell phone plan reimbursements are specifically listed as an excludable business expense.⁸ A reasonable reimbursement does not inflate overtime costs.

Tax Treatment

Cell phone reimbursements can be tax-free for both sides, but only if the arrangement qualifies as an “accountable plan” under IRS rules. Three conditions must be met: the expense must relate to services performed as an employee, the employee must document the expense within a reasonable time, and any excess reimbursement must be returned to the employer within a reasonable time. When all three are satisfied, the reimbursement is excluded from taxable wages and the employer owes no payroll taxes on it.⁹ A flat stipend that requires no substantiation and no return of excess will likely be treated as taxable wages. Employers using the stipend model should weigh the administrative simplicity against the tax cost, and consider whether periodic documentation could preserve the exclusion.

Personal Devices, Company Data

Reimbursing personal phone use creates exposure beyond the expense itself. Text messages and other communications on a personal phone used for business are generally discoverable in litigation. Courts have held that a company can have “possession, custody, or control” over messages on a personal device when the company has a contractual right to access them, and employment agreements requiring device searches or employer access to retrieve business data create exactly that kind of control. Personal texts, photos, and other content on the same device can be swept into discovery alongside the work material. Failure to preserve business-related text messages on personal devices has led to sanctions, fines, and cost awards.

Remote-wipe features raise a parallel problem. Wiping a device typically erases everything on it, including personal photos, contacts, and apps, and destroying personal data through a remote wipe could expose the employer to claims under the Computer Fraud and Abuse Act. A BYOD policy should disclose the remote-wipe capability, explain what data may be affected, and require employees to maintain their own backups.
