Iowa overtime laws are, in practice, federal law. The state has no separate overtime statute, so the Fair Labor Standards Act (FLSA) sets the rules for nearly every worker in Iowa: if you’re non-exempt, your employer owes you at least 1.5 times your regular rate for every hour over 40 in a single workweek. Iowa Code Chapter 91A controls how and when wages must actually be paid, and it gives you a state-level route to collect unpaid overtime, but the overtime obligation itself comes from federal law.1Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours
The 40-Hour Weekly Trigger
Overtime kicks in at 40 hours within a fixed seven-day period that your employer chooses. Every hour past 40 must be paid at 1.5 times your regular rate. Earn $20 an hour and your overtime rate is $30. Salaried but non-exempt? The salary gets converted to an hourly equivalent and the same math runs.
Iowa follows the weekly standard, not a daily one. A 12-hour Monday shift does not, by itself, trigger overtime. Only the cumulative weekly total matters. Your employer picks the seven-day window and has to keep it consistent; shifting it to dodge overtime is not allowed. Each workweek also stands alone. Your employer cannot average a 45-hour week with a 35-hour week and call it even. You are owed five hours of overtime for that first week.2U.S. Department of Labor. Wages and the Fair Labor Standards Act
What Your Regular Rate Actually Includes
The 1.5 multiplier does not apply to your base hourly wage alone. It applies to your “regular rate,” which the FLSA defines to include almost all compensation for the week: non-discretionary bonuses, shift differentials, and commissions get folded in. Only a narrow statutory list of payments (discretionary gifts, certain benefit-plan contributions) can be excluded.3U.S. Department of Labor. Fact Sheet 56A: Overview of the Regular Rate of Pay Under the Fair Labor Standards Act
An example shows how much this changes the number. Say you earn $18 an hour and your employer pays a $200 production bonus for the week. That bonus is spread across all hours worked to find the true regular rate. Fifty hours worked means the bonus adds $4 an hour ($200 ÷ 50), lifting your regular rate to $22. The overtime premium on those 10 extra hours is calculated on $22, not $18. Employers who miss this calculation owe back pay.
Who Is Exempt From Overtime
Not every worker qualifies. The FLSA carves out several exempt categories, and because Iowa has no separate overtime law, the federal exemptions apply unmodified.
White-Collar Exemptions
Executive, administrative, professional, and outside sales employees can be exempt if they pass both a salary test and a duties test. After a federal court vacated the Department of Labor’s 2024 rule, the salary floor reverted to the 2019 level: $684 per week, or $35,568 per year.4U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemption Anyone paid less than that is automatically non-exempt, whatever their job duties look like. A separate “highly compensated employee” test kicks in at $107,432 per year in total compensation.5U.S. Department of Labor. Fact Sheet 17G: Salary Basis Requirement and the Part 541 Exemptions Under the Fair Labor Standards Act
Clearing the salary threshold is not enough. The duties test is where employers most often get exemptions wrong. An executive employee must primarily manage the business or a recognized department and regularly direct the work of at least two full-time employees.6U.S. Department of Labor. Fact Sheet 17A: Exemption for Executive, Administrative, Professional, Computer and Outside Sales Employees Under the Fair Labor Standards Act An administrative employee must perform office work directly tied to management or general business operations and exercise independent judgment on significant matters. A professional role requires advanced knowledge in a specialized field gained through extended education. Outside sales employees primarily work away from the employer’s premises.7Office of the Law Revision Counsel. 29 USC 213 – Exemptions
Job titles do not control the analysis. Your employer cannot label you an “assistant manager” and skip overtime if most of your time goes to stocking shelves or running a register. The actual day-to-day work is what counts.
Agricultural and Seasonal Workers
Many agricultural workers are outside both the federal overtime framework and Iowa’s Chapter 91A protections. The FLSA itself exempts a large share of farm labor from overtime, and Iowa Code 91A separately excludes family members living on the farm, owner-operators and their resident relatives exchanging labor, and neighboring farmers swapping work.8Iowa Legislature. Iowa Code 91A.2 – Definitions Workers at seasonal amusement parks, recreational camps, and similar operations can also be exempt if the business runs no more than seven months per year or meets a revenue-seasonality test.7Office of the Law Revision Counsel. 29 USC 213 – Exemptions
Can Your Employer Give You Comp Time Instead of Pay?
Private employers in Iowa cannot substitute paid time off for overtime cash. The FLSA does not allow it. Even if you would prefer the time off, your employer has to pay money. No handshake agreement, no written policy, changes that.
Government employers are the exception. State agencies, counties, cities, and school districts may offer compensatory time at 1.5 hours off for each overtime hour, but the arrangement must be established before the work is performed. Most public employees can bank up to 240 hours; workers in public safety or emergency response can accrue up to 480. Beyond the cap, additional overtime has to be paid in cash. When a public employee leaves, unused comp time is paid out at the final regular rate.1Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours
Hours You May Not Realize Count
Whether time pushes you past 40 often turns on activities that do not feel like “real work.” The FLSA has specific rules.
Your normal commute is never compensable. Travel between job sites during the workday always counts. If you are sent on a special one-day assignment to another city, the travel is compensable, minus what you would normally spend commuting.9U.S. Department of Labor. Fact Sheet 22: Hours Worked Under the Fair Labor Standards Act Overnight travel is compensable when it falls during your normal working hours, even on a day you would not usually work.
Employer-required training and meetings count as work time unless every one of four conditions is met: the session is outside normal hours, attendance is truly voluntary, the content is not directly related to your job, and you do no other work during it. Miss any one and the time is compensable. A mandatory Saturday safety training is paid time.
On-call time depends on how restricted you are. If you must stay at the workplace or so close that you cannot use the time for your own purposes, you are “engaged to wait” and the hours count. If you only need to leave a phone number and can otherwise go about your life, you are “waiting to be engaged” and the time generally does not count.10U.S. Department of Labor.

How to Recover Unpaid Overtime
You have two routes, and the right one depends on how much you are owed and how long ago the wages came due.
The Iowa DIAL Wage Claim
The Iowa Department of Inspections, Appeals, and Licensing (DIAL) accepts wage claims through its Wage and Child Labor unit, but only when all three conditions are met:
- Less than one year (365 days) since the wages were due.
- The total owed is under $6,500.
- All work was performed in Iowa.
You file using the Iowa Wage Claim Form on the DIAL website, available in English and Spanish.11Department of Inspections, Appeals, & Licensing. How Do I File a Wage Claim Pay stubs, personal time logs, and any employment agreement or handbook strengthen the claim. If DIAL finds the employer intentionally withheld wages, it can pursue the unpaid amount plus liquidated damages and attorney fees.12Iowa Legislature. Iowa Code 91A.8 – Damages Recoverable by an Employee Iowa’s liquidated damages under Chapter 91A accrue at 5 percent of unpaid wages per day (excluding Sundays, holidays, and the first seven days), capped at the total amount unpaid.13Iowa Legislature. Iowa Code 91A – Wage Payment Collection
A Federal FLSA Lawsuit
If your claim exceeds $6,500 or you have already passed Iowa’s one-year deadline, you can sue in federal or state court under the FLSA. The federal statute of limitations is two years from the date the overtime should have been paid, extending to three years for willful violations.14Office of the Law Revision Counsel. 29 USC 255 – Statute of Limitations
A successful FLSA claim recovers the unpaid overtime plus an equal amount in liquidated damages, doubling what you are owed. The employer can avoid the liquidated damages piece only by proving both good faith and reasonable grounds to believe it was complying with the law.15Office of the Law Revision Counsel. 29 USC 260 – Liquidated Damages Courts also award reasonable attorney fees to workers who win, so hiring a lawyer generally does not require money up front.16Office of the Law Revision Counsel. 29 USC 216 – Penalties
Retaliation Is Illegal
The FLSA prohibits your employer from firing, demoting, cutting hours, or otherwise punishing you for filing a wage complaint, starting a legal proceeding, or testifying about overtime violations. The protection covers oral and written complaints, and most courts extend it to internal complaints made to a supervisor rather than a government agency.17U.S. Department of Labor. Fact Sheet 77A: Prohibiting Retaliation Under the Fair Labor Standards Act
If retaliation happens, the remedies include reinstatement, back pay for lost wages, and liquidated damages equal to that lost pay. The protection also outlasts the employment relationship: a former employer who gives a bad reference or interferes with new employment because you filed a claim is violating the same provision.
