Overtime Pay Rules in Iowa: Who Qualifies & What You Earn

The federal Fair Labor Standards Act (FLSA), 29 U.S.C. section 207, requires overtime pay of not less than one-and-a-half times the employee's regular rate of pay for all hours worked over 40 in a workweek. The FLSA applies to covered employers with employees engaged in interstate commerce or in certain industries. The U.S. Department of Labor enforces the FLSA and has established minimum salary thresholds for exempt categories: as of 2024, the standard salary level is $43,888 per year.

Federal law provides four primary exempt categories: executive (supervises employees and makes hiring/firing decisions), administrative (performs office work directly related to management), professional (requires advanced knowledge in a field of learning or artistic talent), and outside sales (works away from employer's place of business making sales). The FLSA allows employers to recover damages through the Department of Labor's Wage and Hour Division, which investigates violations and may assess penalties and back wages.

Employees filing under the FLSA have three years to recover back wages (or two years for liquidated damages in non-willful violations). The FLSA does not prohibit averaging hours across multiple weeks or using salary-only pay systems, provided that the salary meets the threshold and the employee performs exempt duties.

Iowa Code section 91.1 mirrors federal FLSA requirements but provides state-specific protections and enforcement mechanisms. Iowa requires overtime compensation at one-and-a-half times the regular rate for all hours over 40 in a workweek for covered employees, applying the same definition of "workweek" as federal law (a fixed and recurring period of 168 hours or seven consecutive 24-hour periods).

Iowa's exempt categories match the federal FLSA structure: executive (managing a department or subdivision with authority to hire, fire, and discipline), administrative (performing office or nonmanual work directly related to management or general operations), professional (performing work requiring specialized knowledge obtained through extended study, or artistic talent), and outside sales (working away from the employer's place of business making sales). Iowa Code section 91.3 does not impose a separate state salary threshold; employers must apply the federal threshold established by the U.S. Department of Labor.

Unlike federal law, Iowa prohibits certain practices that the FLSA permits. Iowa employers cannot average hours across multiple weeks to avoid overtime liability, nor can they classify an employee as salaried only to avoid computing overtime based on actual hours worked. Iowa requires that overtime be calculated based on the employee's actual regular hourly rate, including commissions and bonuses that are part of the compensation bargain.

Iowa covers all private-sector employees not meeting the exempt criteria, including temporary workers, independent contractors (if classified incorrectly), and part-time employees. Iowa provides no carve-outs for industries or company sizes—all employers are covered regardless of revenue or employee count. The Iowa Department of Labor enforces overtime requirements through wage claims filed under Iowa Code section 91.6. Remedies include back wages, penalties of up to 25 percent of unpaid wages, court costs, and attorney fees in some cases. The state recovery period is two years from the date of violation, shorter than the federal three-year period but longer than the two-year federal period for liquidated damages.

Iowa law provides exemptions for specific employee categories defined in Iowa Code section 91.3, which closely track federal FLSA exemptions. Executives are exempt if they supervise at least two employees, have authority to hire and fire (or make effective recommendations), and perform management duties as a primary responsibility. Administrators are exempt if they perform office or nonmanual work directly related to business operations or management and exercise independent judgment on significant matters. Professionals are exempt if they perform work requiring specialized knowledge obtained through extended study in a field of learning, or if they possess artistic talent.

Outside salespeople are exempt if they make sales away from the employer's place of business and work primarily in sales capacity. However, merely having a sales title does not qualify for this exemption; the employee must work primarily away from the employer's location.

Iowa recognizes no exemption for agricultural employees, domestic workers, or nonprofit employees based on organization type alone. Commissioned salespeople inside the employer's place of business are not exempt and must receive overtime if working over 40 hours per week, even if their compensation includes commission.

Iowa also recognizes no de minimis exception for brief overtime work; any work over 40 hours in a workweek triggers overtime liability. Salary-only employees are not automatically exempt; the salary must meet the federal threshold and the employee must perform exempt duties. An employer's misclassification of an employee as independent contractor does not exempt the employer from overtime liability if the worker is actually an employee under Iowa common law tests (control over work, permanence, and integration into business).

Step 1 — Document the Violation: Keep detailed time records showing all hours worked daily, including date, start time, end time, and total hours. Document your job title, job duties, and salary or hourly rate in writing. Save email communications, offer letters, and pay stubs that show compensation structure. Take screenshots or print copies of employer time-tracking systems showing hours. Create a dated log noting when overtime was worked but not paid, including the calculation of what overtime pay should have been (1.5 times regular hourly rate times overtime hours). Store these documents in a safe location outside your workplace, such as a personal email or cloud storage.

Step 2 — Initiate Internal Complaint: Notify your employer of the overtime violation in writing, such as an email to payroll or human resources, clearly stating the dates when overtime was not paid, the hours involved, and the amount owed. Keep a copy of this communication. Request a written response explaining why overtime was not paid. Document your employer's response and any promises to remedy the violation. This internal complaint creates evidence of the employer's knowledge and may strengthen your claim. If the employer refuses to address the issue or retaliates, this becomes part of your record.

Step 3 — File a Wage Claim with the Iowa Department of Labor: Wage claims are filed with the Iowa Department of Labor Wage and Hour Bureau. You have two years from the date of the violation to file. Submit Form "Wage Claim" (available at iowadol.gov) or file online through the Department of Labor's wage claim portal. Include your name, address, phone number, employer name and address, dates of violations, total hours of unpaid overtime, your regular hourly rate, and the amount you believe is owed. Attach copies of pay stubs, time records, and your documented communications with the employer. The Department will send a copy to the employer and schedule a hearing if the employer disputes the claim.

Step 4 — Participate in Investigation and Hearing: The Iowa Department of Labor will contact you to confirm receipt of your claim and may request additional documentation, such as employment contracts or a timeline of all overtime worked. The employer will be notified and given an opportunity to respond. If the employer disputes the claim, an investigative hearing will be scheduled, typically within 30 to 60 days. You should prepare a presentation showing your work hours, the overtime owed, and your regular rate of pay. Bring all documentation including time records, pay stubs, and written communications. The Department may also interview the employer and review company records. The investigation process typically takes 60 to 90 days. The Department will issue a decision awarding or denying the claim; the losing party may appeal to the Iowa District Court within 30 days.

Step 5 — Consult an Attorney: Contact an employment lawyer if your claim is substantial (typically $2,000 or more), if the employer disputes the claim, or if the employer retaliates. An employment attorney can help you calculate the correct overtime owed, including penalties and potential damages. Iowa allows recovery of attorney fees in wage claim cases if you prevail. An attorney can also represent you in an appeal to District Court if the Department of Labor's decision is unfavorable. Seek an attorney who specializes in wage and hour law and employment disputes in Iowa; many offer free initial consultations.
