Iowa Mileage Reimbursement: §91A.3(7) and the 30-Day Rule

Iowa requires employers to reimburse "authorized expenses," including mileage, within 30 days under Iowa Code §91A.3(7). Late or refused reimbursement triggers liquidated damages of 5% per day under §91A.8. Iowa is one of the more aggressive states on enforcement, paired with a flat 3.8% income tax that simplifies the deduction math.

The Statute: §91A.3(7) and the 30-Day Rule

Iowa Code §91A.3(7) requires employers to reimburse "authorized expenses" within 30 days of submission, or within the timeline specified in the employer's written policy, whichever is shorter.

The key word is "authorized." Three things matter:

• Express authorization. The employer told you (in writing or verbally) to use your personal vehicle, or it's documented in your job description or policy.
• Implied authorization. The work cannot be performed without driving (a sales rep with a defined territory, a service tech with a route). Courts and Iowa Workforce Development have read this as implicit authorization.
• Submission triggers the clock. The 30 days starts when you submit the expense with a mileage log, not when the trip happens.

The statute does not name mileage specifically. But Iowa Workforce Development and Iowa courts have consistently treated work-required mileage as an authorized expense within §91A.3(7).

The Penalty Structure: §91A.8

Iowa Code §91A.8 provides liquidated damages for unpaid wages and reimbursable expenses:

• 5% per day of the unpaid amount, capped at the unpaid amount itself
• Attorney fees and court costs for prevailing employees, regardless of recovery size
• Statutory standing to bring private civil action

In plain terms: if your employer owes you $500 in unreimbursed mileage and refuses to pay, you can be entitled to $25/day in damages on top, capped at another $500. After 20 days, you're owed double. After that, the damages cap, but attorney fees keep accruing. Iowa is one of the few states where the math actually pushes employers to pay quickly.

Enforcement Path

Where the Rule Bites Hardest

• Agricultural sales and crop service contractors driving across the Corn Belt
• Delivery drivers for regional distributors covering Iowa's spread-out small-town network
• Home health workers in rural service areas
• Mobile trades covering long distances between Cedar Rapids, Des Moines, Davenport, and Sioux City
• Field reps for ag tech and equipment dealers

How to Track Your Miles

The same record satisfies both the IRS deduction requirement and a §91A.3(7) reimbursement claim: date, starting and ending location, business purpose, miles driven. See our mileage log requirements guide. Because the 30-day clock starts at submission, monthly submission cadence is the cleanest workflow.

1099 vs W-2

§91A.3(7) protects W-2 employees. Independent contractors are not covered. If you are 1099, deduct on Schedule C. See the Iowa self-employed mileage guide.

FAQ

Does Iowa require employers to reimburse mileage?

Yes, under Iowa Code §91A.3(7), when the driving is authorized by the employer (expressly or impliedly). Reimbursement is due within 30 days of the employee submitting proof.

What's the penalty if my employer is late?

5% per day in liquidated damages under §91A.8, capped at the unpaid amount, plus attorney fees and court costs for prevailing employees.

How long do I have to file a wage claim in Iowa?

Iowa wage claims are subject to a two-year statute of limitations under Iowa Code §614.1(8) for actions to recover wages. File sooner rather than later to maximize damages.

Is mileage explicitly named in §91A.3(7)?

No. The statute uses broad "authorized expenses" language. Iowa Workforce Development and case interpretation have consistently treated work-required mileage as covered.

Does this apply to gig drivers and independent contractors?

No. §91A.3(7) applies to W-2 employees. If you are a 1099 contractor, you cannot file a wage claim, but you can deduct your business mileage on your federal Schedule C return.

What about commuting?

Commuting from home to your regular workplace is not "authorized" for reimbursement purposes. The trip has to be in service of the employer's business beyond the commute.
