Iowa Overtime Law: Daily Overtime, the 40-Hour Rule, and Exemptions

Iowa does not have its own overtime statute and does not require daily overtime. There is no Iowa rule that pays a premium for working more than 8 hours in a single day. Instead, overtime for Iowa workers is governed entirely by the federal Fair Labor Standards Act (FLSA), which requires covered, non-exempt employees to be paid at least one and one-half times their regular rate for all hours worked over 40 in a single workweek. So if you work four 11-hour days (44 hours) in Iowa, you are owed 4 hours of overtime because you crossed 40 for the week, not because any day ran long.

This is one of the most common points of confusion. A handful of states (such as California, Alaska, Nevada, and Colorado) impose daily overtime after 8 or 12 hours. Iowa is not one of them. In Iowa, a 10-hour shift followed by a short week with no overall total above 40 hours generally produces no overtime at all under the law.

The 40-Hour Workweek Rule in Iowa

Because Iowa defers to the FLSA, the building block for overtime is the workweek: a fixed, recurring period of 168 hours (seven consecutive 24-hour days). An employer can choose when that week starts, but once set it should stay consistent. Overtime is calculated week by week. Employers generally cannot average two weeks together — if you work 30 hours one week and 50 the next, you are owed 10 hours of overtime for the second week even though the two-week average is only 40.

The overtime rate is 1.5 times your regular rate of pay, which is not always just your base hourly wage. The regular rate must include most non-discretionary bonuses, shift differentials, and commissions. For example, a production or warehouse worker in Iowa who earns an attendance or output bonus may have an overtime rate slightly higher than 1.5 times the base hourly figure, because the bonus must be folded into the regular rate before the multiplier is applied.

Minimum Wage Context

Iowa's minimum wage is tied to the federal floor. As of 2026, Iowa's minimum wage is $7.25 per hour — the same as the federal FLSA minimum of $7.25 — and Iowa law prohibits cities and counties from setting a higher local minimum. Tipped employees may be paid a lower cash wage (around $4.35 per hour) as long as tips bring them up to the full minimum. Because these figures can be adjusted, confirm the current numbers with Iowa Workforce Development before relying on them. Overtime is calculated on the actual regular rate, which for most workers is well above the minimum wage.

Who Is Exempt From Overtime in Iowa

Since Iowa follows the FLSA, the exemptions are the federal ones. The most common are the "white-collar" exemptions, which require both a salary test and a duties test — a job title alone never makes someone exempt:

• Executive: employees whose primary duty is managing the business or a department, who regularly direct at least two full-time employees, and who have authority over hiring and firing.
• Administrative: employees whose primary duty is office or non-manual work directly related to management or general business operations, exercising independent judgment on significant matters.
• Professional: employees in fields requiring advanced knowledge (such as law, medicine, accounting, or engineering) or recognized creative work.
• Outside sales and certain computer professionals.

To qualify for most of these exemptions, the employee must be paid on a salary basis above the federal salary threshold. That threshold has changed in recent years and remains subject to litigation and rulemaking, so verify the current dollar figure with the U.S. Department of Labor rather than assuming an old number still applies. Other FLSA exemptions cover certain agricultural workers, some transportation employees regulated by the Motor Carrier Act, and specific seasonal operations — categories that matter in Iowa given the state's large farming and trucking sectors.

Being paid a salary does not by itself make you exempt. Many salaried Iowa workers are still entitled to overtime because their actual job duties do not meet the legal test. Misclassification — labeling a worker "salaried exempt" or an "independent contractor" to avoid overtime — is a frequent source of wage claims.

How to Recover Unpaid Overtime in Iowa

If you believe you are owed overtime, you have two main paths, and you can often pursue them together.

1. The federal route (FLSA). You can file a complaint with the U.S. Department of Labor's Wage and Hour Division, which enforces overtime nationwide, or you can file a private lawsuit. Under the FLSA, the statute of limitations is two years, extended to three years if the violation was willful. Successful claims can recover the unpaid overtime plus an equal amount in liquidated (double) damages, along with attorney's fees.

2. The Iowa route (Wage Payment Collection Law). Iowa Code Chapter 91A, the Iowa Wage Payment Collection Law, requires employers to pay all wages owed, including earned overtime, on regular paydays. You can file a wage claim with the Iowa Division of Labor, part of Iowa Workforce Development, or sue in state court. Chapter 91A allows recovery of unpaid wages and, where the employer acted intentionally, additional liquidated damages plus court costs and attorney's fees.

Practical steps strengthen any claim:

• Keep your own record of hours worked each day and week, including start and end times and unpaid work performed off the clock.
• Save pay stubs, schedules, time sheets, and any written communications about hours or pay.
• Act promptly — because the limitations clock runs continuously, waiting can permanently cut off the oldest weeks of unpaid overtime.
• Note that the FLSA prohibits retaliation against workers who assert overtime rights; firing or punishing someone for complaining can create a separate legal claim.

Where to Verify Iowa's Rules

For state wage-claim procedures, minimum wage updates, and filing forms, the authoritative Iowa source is Iowa Workforce Development and its Division of Labor. For overtime coverage, exemptions, and the salary threshold, the U.S. Department of Labor, Wage and Hour Division is the controlling federal authority. Because both the federal salary threshold and minimum wage figures can change, always confirm the current numbers directly with these agencies before acting. When state and federal rules overlap, the law that is more favorable to the worker generally applies — but for overtime specifically, Iowa adds nothing beyond the federal 40-hour standard.

Federal law and local ordinances may also apply. Federal laws like the Fair Labor Standards Act set a national floor, and your city or county may add protections (such as a higher local minimum wage or paid sick leave). Check both alongside Iowa state law.
