Iowa HR Compliance Guide for Employers
Iowa employment law guide for small businesses: ICRA 4-employee threshold, wage payment rules, IOSHA, tax updates, and hiring compliance in 2026.
Iowa HR Compliance
ICRA anti-discrimination covers 4+ employees, Iowa WPCL liquidated damages, IOSHA state OSHA plan, $4.35/hr tipped minimum, 3.8% flat income tax, state WARN at 25 employees
Iowa is a moderately employer-friendly state with a right-to-work law dating to 1947 and no paid leave mandate, but several compliance features are significantly more protective than federal law. Those rules are where a small business without an HR department gets caught, and they cost real money when you miss them.
The Iowa Civil Rights Act (ICRA) and its 4-employee threshold mean virtually every business in the state faces anti-discrimination obligations from the very first few hires. The Iowa Wage Payment Collection Law (WPCL), with its liquidated damages formula and mandatory attorney fees, makes intentional paycheck delays expensive. And Iowa's state WARN Act at 25 employees puts advance layoff notice obligations on a large share of small businesses.
This guide covers all major Iowa employer obligations as of 2026, with attention to the rules most commonly misrepresented in compliance resources. Iowa is a State Plan OSHA state (not federal OSHA). The drug testing statute is §730.5 (not Chapter 730A, which does not exist). Gender identity was removed from ICRA effective July 1, 2025, the income tax rate is 3.8% flat (not 3.9%), and local employment ordinances are fully preempted by HF 295 (signed in 2017, not 2019).
What Makes Iowa Different from Other States for HR Compliance
Iowa's compliance environment pairs light regulation with a handful of specific provisions that create outsized risk for small employers who don't know about them. The HR onboarding process in Iowarequires attention to the ICRA threshold, the WPCL wage recovery framework, and the Iowa OSHA (IOSHA) inspection program before the first employee starts.
Three Iowa compliance features are most consequential for small businesses. First, the ICRA 4-employee threshold means a 5-person business faces the full range of state anti-discrimination obligations, including the Iowa Equal Pay Act, the pregnancy leave requirement, and the revised gender identity rules.
Second, the Iowa WPCL's liquidated damages formula means an intentionally withheld $1,000 paycheck costs $50 a day once the 7-day grace period ends. It reaches the full $1,000 cap after 20 more counted days (Sundays and legal holidays are skipped), plus attorney fees. Third, Iowa's state WARN Act at 25 employees requires 30 calendar days' advance notice for layoffs, which puts it well within reach of small businesses.
Iowa Employment Law Fundamentals Every Employer Should Know
At-will employment and its limits
Iowa is an at-will employment state. Neither party is required to explain the reason for termination. Iowa courts recognize two exceptions and have rejected a third. The public policy exception, established in cases including Davis v. Horton (661 N.W.2d 533, 2003), protects employees from discharge for filing workers' comp claims, jury service, whistleblowing, and refusing to commit illegal acts.
The implied contract exception, established in Jones v. Lake Park Care Center (569 N.W.2d 369, 1997), means employee handbook policies can create binding contractual obligations if no conspicuous at-will disclaimer is present. The rejected one is the implied covenant of good faith and fair dealing: Iowa courts have specifically refused to treat it as a separate exception.
Iowa Civil Rights Act overview
Iowa Code Chapter 216 covers employers with 4 or more employees, counting everyone except members of the employer's family. The Iowa Civil Rights Commission has sat within the Iowa Office of Civil Rights since July 1, 2024, and that is where an ICRA complaint goes.
The ICRA filing deadline is 300 days from the incident. A complainant can also get a 60-day administrative release, the right-to-sue letter that moves the claim to court, under §216.16.
Right-to-work
Iowa has been a right-to-work state since 1947 under Iowa Code Chapter 731, one of the first states to enact such a law. Union membership, dues, and fees cannot be required as a condition of employment. Violation is a serious misdemeanor under §731.6.
Hiring and Onboarding Requirements in Iowa
Iowa new hire paperwork includes a state-specific withholding form and a 15-day new hire reporting deadline that is stricter than the federal default.
Background checks
Iowa has no statewide ban-the-box law for private employers. Waterloo's Ordinance 5522, approved November 4, 2019, bars criminal history questions on any employer's job application and, for employers with 15 or more employees, any inquiry before a conditional offer of employment.
The Iowa Supreme Court settled how far that goes in ABI v. City of Waterloo, decided June 18, 2021. The ordinance survives where it regulates the timing of criminal history inquiries, because timing is not a term or condition of employment. It is preempted by §364.3(12), the state preemption statute, where it tries to limit whether an employer may consider criminal history at all.
The federal Fair Credit Reporting Act (FCRA) applies in Iowa with no state additions layered on top. Its seven-year reporting cap covers arrests and civil judgments rather than convictions, which carry no federal time limit, and the cap falls away entirely once the job pays $75,000 or more.
SF 2340 (2024) is an immigration enforcement law and has nothing to do with ban-the-box, despite being cited that way in several compliance summaries.
Non-compete agreements
Iowa has no non-compete statute. Enforceability is governed entirely by common law using the three-factor test from Lamp v. American Prosthetics, 379 N.W.2d 909 (Iowa 1986): is the restriction reasonably necessary to protect the employer's business, is it unreasonably restrictive of the employee's rights, and is it prejudicial to the public interest.
Duration and geography are judged case by case under that test rather than against any fixed limit, and in Lamp itself the covenant was held unenforceable. Pay in hiring is just as lightly regulated: Iowa has no pay transparency law and no salary history ban.
Iowa Wage and Hour Rules That Catch Employers Off Guard
Iowa's wage and hour framework is among the most employee-protective in the Midwest. The WPCL liquidated damages formula and the Iowa tipped minimum wage are the two provisions most frequently applied incorrectly.
Minimum wage and tipped employees
Iowa's minimum wage is $7.25 per hour, matching the federal floor. For tipped employees, Iowa's tip credit is capped at 40% of minimum wage under §91D.1(1)(c), which leaves a cash wage of $4.35 per hour. Federal law lets an employer take a tip credit of $5.12, roughly 71% of the wage, and pay $2.13 in cash, so the Iowa floor is more than double the federal one.
Employers entering Iowa from states that follow the federal tip credit underpay tipped employees on this point constantly. The Iowa provision reaches employees of restaurants, hotels, motels, inns, and cabins who customarily and regularly receive more than $30 a month in tips. If tips plus the cash wage do not reach $7.25 an hour for the workweek, the employer makes up the difference.
Iowa has a minimum wage statute of its own, and the state figure is a fixed $7.25 with no indexing. Section 91D.1(1)(b) requires the state rate or the current federal minimum, whichever is greater, so the federal rate governs if Congress raises it. The Iowa minimum wage page sets out the exceptions that still apply, the tipped and youth rates, and the poster requirement.
An initial employment wage of $6.35 per hour applies for the first 90 calendar days for new hires under §91D.1(1)(d). An employer covered by the federal FLSA may use it only for hires under 20, under the federal youth opportunity wage in 29 U.S.C. 206(g); every other hire at a covered employer must get $7.25 from the first day. The federal rule also bars displacing current staff to make room for youth-wage hires.
The state minimum wage requirements do not reach an enterprise whose annual gross volume of sales or business done is less than $300,000, unless it falls in a carve-out. The carve-outs at §91D.1(2)(c) cover laundry and cleaning businesses, construction, hospitals and care institutions, schools, and public agencies at any volume.
No breaks required for adults
Iowa does not require meal or rest breaks for adult employees. Iowa Code §92.7 requires only a 30-minute break for minors under 16 after 5 consecutive hours of work. Toilet breaks are required for all employees under general OSHA standards.
Multiple compliance resources incorrectly state that Iowa requires 10-minute rest breaks and 30-minute meal breaks for all employees. It does not, as the FAQ from the Iowa Department of Inspections, Appeals, and Licensing (DIAL) and other official sources confirm.
Overtime: federal rules with no state layer
Iowa has no overtime statute of its own. Chapter 91D sets the minimum wage and Chapter 91A governs how and when wages are paid, but neither sets a premium rate. That means overtime in Iowa runs entirely on the federal Fair Labor Standards Act (FLSA): time and one-half the regular rate for hours worked beyond 40 in a workweek, per the U.S. Department of Labor.
Three consequences follow for Iowa employers. There is no daily overtime trigger, so a 12-hour Tuesday inside a 38-hour week earns no premium. Weekend, holiday, and night hours carry no state premium either. And the salary test for the executive, administrative, and professional exemptions is the federal $684 per week ($35,568 per year), the figure the Department of Labor restored to the regulations in 2026 after the 2024 increase was vacated in court and then rescinded.
No Iowa statute caps daily or weekly hours for adult employees, so requiring overtime is lawful as long as the premium is paid. Employees under 16 are the exception, with daily and weekly hours capped by Iowa Code §92.7. Because the obligation itself is federal, unpaid overtime is a complaint to the U.S. Department of Labor Wage and Hour Division rather than to DIAL.
Iowa Wage Payment Collection Law (Ch. 91A)
| Rule | Detail |
|---|---|
| Liquidated damages | Owed only where the failure to pay was intentional (§91A.8): 5% of unpaid wages per day, excluding Sundays and legal holidays, after a 7-day grace period; capped at 1× unpaid wages (§91A.2(6)) |
| Maximum recovery | 2× unpaid wages (unpaid wages + full liquidated damages cap) plus court costs and attorney fees, for intentional nonpayment (§91A.8) |
| Attorney fees | Mandatory for prevailing employee in both intentional and non-intentional violations (§91A.8) |
| Wage definition (§91A.2(7)) | Broad: includes vacation pay, holiday pay, sick leave pay, severance pay, pension contributions, health insurance benefits |
| Deduction prohibitions (§91A.5) | Prohibited: cash shortage deductions in shared tills, breakage, bad checks, lost property, tip deductions, PPE costs |
| Conceded amounts (§91A.7) | Employer must pay undisputed wages unconditionally even when other amounts are in dispute |
| Anti-retaliation (§91A.10(5)) | Reinstatement plus back pay for employees retaliated against for exercising WPCL rights |
| Civil penalty | Up to $500 per pay period per violation (§91A.12) |
| Overdraft liability (§91A.3(3)(b)) | Employer pays any overdraft charge created because wages were not paid by the regular payday |
Pay frequency and pay stubs
Iowa requires pay at least monthly, semimonthly, or biweekly on a regular payday, with payment no later than 12 days (excluding Sundays and holidays) after the close of the pay period (§91A.3(1)). Pay stubs must include hours worked, wages earned, and deductions made (§91A.6(4)). FLSA-exempt employees do not need hours worked on the stub. Electronic delivery via portal is permitted.
Keep payroll records for three years in any case, because the FLSA requires it under 29 CFR 516.5. Iowa's own three-calendar-year rule in §91A.6(1) is narrower. It binds an employer only once the DIAL director sends notice, which happens after the employer has paid a wage claim or been assessed a civil penalty.
Iowa Child Labor Rules for Employers Hiring Minors
Iowa child labor law sits in Iowa Code Chapter 92, and the 2023 rewrite under SF 542 left the state limits on 14 and 15 year olds looser than the federal ones. An employer covered by both Chapter 92 and the FLSA follows whichever standard protects the minor more, which in nearly every scheduling decision is the federal standard.
| Rule for 14 and 15 year olds | Iowa (Ch. 92) | Federal (FLSA) |
|---|---|---|
| Hours of the day, school year | 7 a.m. to 9 p.m. | 7 a.m. to 7 p.m. |
| Hours of the day, June 1 through Labor Day | 7 a.m. to 11 p.m. | 7 a.m. to 9 p.m. |
| Maximum on a school day | 6 hours | 3 hours |
| Maximum in a week while school is in session | 28 hours | 18 hours |
| Maximum on a non-school day | 8 hours | 8 hours |
| Maximum in a week when school is out | 40 hours | 40 hours |
| Break | 30 minutes once the shift reaches 5 hours | No federal break requirement |
| Minimum age for most non-farm work | 14 | 14 |
The Iowa column comes from Iowa Code §92.7 and the federal column from Wage and Hour Division Fact Sheet 43. Build the schedule to the stricter column.
A 15-year-old closing at 9 p.m. on a school night is lawful under §92.7 and a federal violation in the same shift, and federal child labor violations carry civil money penalties per minor. FLSA coverage reaches most Iowa businesses through enterprise or individual coverage, so the federal limits are the safer working rule. Our guide to child labor laws covers the federal side in more detail.
Sixteen and seventeen year olds
Iowa Code §92.7A puts 16 and 17 year olds on adult hours: no curfew, no daily cap, no weekly cap under state law. What still binds is the work itself. Section 92.8 prohibits minors from listed hazardous tasks, and the federal hazardous occupation orders apply on top, covering driving on the job, most power-driven equipment, roofing, wrecking, and excavation.
Iowa Code §92.8A lets an employer apply for a waiver so a 16 or 17 year old in an approved work-based learning, internship, or registered apprenticeship program can perform certain otherwise-prohibited tasks under supervision. A state waiver does not lift the federal orders, so the arrangement still has to fit a student-learner or apprentice exemption under the FLSA.
Work permits and proof of age
There is no longer a state work permit to collect. Iowa Code §92.10, which required a permit on file for a minor employee, was repealed in 2023, so nothing has to be filed before a 15-year-old starts a shift.
Keep proof of age in the personnel file regardless. It is the only evidence that the schedule you built was lawful for that worker, and it shows who is owed the 30-minute break in Iowa Code §92.7 that adult employees in Iowa do not get. Detailed state guidance sits with the Department of Inspections, Appeals, and Licensing.
Leave Laws in Iowa
Iowa mandates very little leave for private employers beyond pregnancy leave tied to the ICRA.
| Leave Type | Threshold | Duration | Key Notes |
|---|---|---|---|
| Pregnancy leave (§216.6(2)(e)) | 4+ employees | The period of disability or 8 weeks, whichever is less | No tenure or hours requirement; covers disability from pregnancy, childbirth, or related medical conditions; medical certification may be required |
| Veterans Day leave (§91A.5A) | All employers, veteran employees only | The Veterans Day holiday | Paid or unpaid at employer discretion; employee gives at least one month’s written notice plus discharge papers; employer answers at least 10 days before November 11 |
| Voting leave (§49.109) | All employers | Enough paid time to total 2 consecutive hours | Employee applies in writing before Election Day and the employer picks the hours; nothing is owed if the employee already has 2 consecutive non-working hours while the polls are open |
| Jury duty (§607A.45) | All employers | Duration of service | Job-protected and pay not required; violation is contempt, and a discharged juror has 60 days to sue for reinstatement, up to 6 weeks of lost wages, and attorney fees |
| Military leave (§29A.43) | All employers | Duration of service | Unpaid; reinstatement rights; leave does not affect vacation/sick/bonus accrual; includes Civil Air Patrol |
| Emergency response leave (§100B.14) | All employers | Duration of emergency | Volunteer firefighters, EMS providers, and reserve peace officers who gave written notice; the employer decides whether the employee may leave to respond, and pay may be deducted for the absence |
| Federal FMLA | 50+ employees within 75 miles | 12 weeks unpaid | No Iowa state equivalent for private sector |
| Paid sick leave | No mandate | N/A | No Iowa state paid leave law |
| Domestic violence leave | No standalone statute | N/A | §915.23 protects employees serving as witnesses/parties in DV proceedings from discharge |
Pregnancy leave: 4-employee threshold
Iowa Code §216.6(2)(e) requires employers with 4 or more employees to provide up to 8 weeks of unpaid pregnancy leave. This is broader than federal FMLA in two ways: the 4-employee threshold is much lower than FMLA's 50-employee threshold, and there is no tenure or hours-worked requirement. Leave applies to pregnancy, childbirth, miscarriage, abortion, and related medical conditions. The employer may require medical certification and timely notice.
Anti-Discrimination: Iowa Civil Rights Act Deep Dive
The ICRA's 4-employee threshold is the single most important compliance fact for small Iowa businesses. Once you reach that headcount, ICRA covers you in full, so build your anti-discrimination compliance framework the day you hire your 4th employee.
| Protection | Iowa ICRA | Federal Law |
|---|---|---|
| Employer threshold | 4+ employees (family members excluded): Iowa Code §216.6(6)(a) | 15+ employees (Title VII, ADA); 20+ (ADEA) |
| Age discrimination | Protected from age 18+ (§216.6) | Protected from age 40+ (ADEA) |
| Gender identity | Removed July 1, 2025 (SF 418) | Protected under Title VII per Bostock (2020) for 15+ employers |
| Sexual orientation | Protected (retained after SF 418) | Protected under Title VII per Bostock for 15+ employers |
| Pregnancy | Protected; up to 8 weeks unpaid leave at 4+ employees (§216.6(2)(e)) | Protected; PWFA accommodation at 15+; PDA at 15+ |
| Filing deadline | 300 days from incident (IOCR) | 180 or 300 days (EEOC, deferral state) |
| Damages cap | None specified in ICRA | $50,000 to $300,000 caps under Title VII based on employer size |
| Equal pay | 9+ protected classes (§216.6A); 4-employee threshold; 2× wage differential damages | Sex only (federal EPA); equal work standard |
SF 418 and the removal of gender identity from ICRA
Iowa became the first state to remove an existing gender identity protection from its civil rights law when Governor Reynolds signed SF 418 on February 28, 2025. The law took effect July 1, 2025, removing gender identity from all sections of ICRA and redefining sex as a person's biological sex as either female or male.
Sexual orientation remains a protected class under ICRA. Employers must update anti-discrimination policies, training, and complaint procedures to reflect this change.
The transition window has now closed. ICRA gives a complainant 300 days from the incident, so the last day to file a state gender identity complaint over conduct before July 1, 2025 was April 27, 2026, as the Iowa Office of Civil Rights confirms.
What remains is federal: Title VII continues to protect gender identity under Bostock v. Clayton County (2020) for employers with 15 or more employees. That leaves an Iowa employer of 4 to 14 people outside both regimes on gender identity, and fully inside ICRA on every other ground.
Iowa Equal Pay Act (§216.6A)
Iowa's equal pay law, enacted in 2009, covers 9 protected classes compared to the federal Equal Pay Act's single sex-only standard. It applies at 4 or more employees. Damages are 2 times the wage differential for standard violations and 3 times for willful violations, plus attorney fees. Each paycheck constitutes a new occurrence, similar to the federal Lilly Ledbetter Act. The correct citation is §216.6A; §91A.8 is the WPCL damages section.
Workplace Safety and Workers' Compensation
Iowa requires workers' compensation from the very first employee and operates its own OSHA State Plan.
The Iowa workers compensation page has the detail: the headcount at which coverage becomes mandatory, who is excluded, where to buy the policy, the injury reporting deadlines, and what going without coverage costs.
Iowa OSHA (IOSHA): state plan state
Iowa has operated an OSHA-approved State Plan since its initial approval on July 20, 1973, under Iowa Code Chapter 88, covering private sector workplaces as well as state and local government. IOSHA sits in the Division of Labor Services at the Department of Inspections, Appeals, and Licensing (DIAL), online at dial.iowa.gov/iosha.
IOSHA conducts the private sector safety inspections in Iowa. Federal OSHA's jurisdiction here is limited to federal government operations, USPS, maritime, and certain interstate bridge construction. Free on-site consultation is available to smaller employers, and penalties track the federal amounts across the willful, serious, non-serious, and failure-to-abate categories.
Workers' compensation
Iowa Code Chapters 85, 85A, 86, and 87 require all Iowa employers with one or more employees to carry workers' compensation coverage. You can either buy insurance from a licensed carrier or register as a self-insured employer.
Exemptions from the coverage requirement include sole proprietors, partners, and LLC members (who may elect coverage under §85.1A); up to four corporate officers who knowingly reject coverage under §87.22; nonprofit directors and officers who are not also full-time employees; and certain casual and agricultural employment.
Benefit payments run on a fixed clock. Under Iowa Code §85.30, weekly compensation payments begin on the eleventh day after the injury, and unpaid amounts carry judgment-rate interest from the date they came due.
Going without coverage is expensive in a specific way. Iowa Code §87.21 lets the injured employee sue at law instead, and in that suit the employer's negligence is presumed, the burden of rebutting it sits with the employer, and the common law defenses of contributory negligence, assumption of risk, and the fellow servant rule are all off the table. Willfully and knowingly doing business without coverage is a class D felony under §87.14A.
Required Workplace Postings for Iowa Employers
Iowa employers must display both state and federal required workplace posting notices. State posters are available at Iowa Workforce Development's poster page. Iowa Workforce Development no longer distributes all-in-one posters, so you download each agency's poster separately.
| Required Iowa Poster | Who Must Post |
|---|---|
| Safety and Health Protection on the Job (IOSHA) | All employers; minimum 8.5" × 14" |
| Your Rights Under Iowa’s Minimum Wage | Covered employers |
| Unemployment Insurance Notice | All employers |
| Iowa Smokefree Air Act (No Smoking) | All employers |
Federal required postings include EEO Know Your Rights (EEOC, which also carries the Pregnant Workers Fairness Act notice for employers with 15 or more employees), USERRA, FLSA minimum wage, FMLA (50+ employees), and the Employee Polygraph Protection Act. The federal OSHA Job Safety and Health Protection poster is the exception: Iowa employers must post the IOSHA version instead to meet the safety poster requirement.
Employee Privacy and Data Protection in Iowa
Iowa CDPA: employee data sits outside the consumer definition
The Iowa Consumer Data Protection Act (CDPA; Iowa Code Chapter 715D, SF 262, effective January 1, 2025) explicitly excludes employee data from its scope. Section 715D.1 defines a consumer as a resident acting only in an individual or household context, "excluding a natural person acting in a commercial or employment context." Data collected and processed in the employment relationship is not subject to CDPA consumer rights or employer obligations.
Under §715D.2 the CDPA covers a business that controls or processes the personal data of at least 100,000 consumers in a calendar year, or at least 25,000 consumers where it derives over 50% of gross revenue from selling personal data. Enforcement is by the Iowa Attorney General exclusively, with a 90-day cure period and penalties up to $7,500 per violation; there is no private right of action.
Recording consent (§808B.2) and personnel files (§91B.1)
Iowa is a one-party consent state under §808B.2 (the correct citation; chapter 808A covers school student searches, not recording consent). One party to a communication may record without notifying others. Violation is a Class D felony under §808B.2 and a serious misdemeanor under §727.8 (Eavesdropping).
Personnel file access is a separate right. Iowa Code §91B.1 gives employees the right to access and copy their personnel file, including performance evaluations and disciplinary records, but excluding employment references written about the employee. Iowa has no social media privacy law restricting employer requests for personal account credentials.
Iowa Code §91B.2 gives employers immunity from civil liability when they share work-related information with prospective employers, with exceptions for civil rights violations and malicious or untrue information.
Termination, Separation, and Layoff Compliance
Iowa's separation procedures are governed by the WPCL for final pay timing and by the Iowa WARN Act for mass layoffs.
Final paycheck: same rule for all separations
Iowa Code §91A.4 requires wages to be paid by the next regular payday for the pay period in which they were earned, regardless of whether the separation is a discharge, layoff, or voluntary quit. Commission wages have a 30-day calculation period.
Two related rules can raise what you owe. If the employer's policy provides for pro-rata vacation payout, accrued vacation is wages subject to WPCL enforcement. If a late paycheck creates an overdraft charge on the employee's account, the employer is liable for that charge (§91A.3(3)(b)).
Iowa WARN Act (Ch. 84C): 25-employee threshold
Iowa Code Chapter 84C requires employers with 25 or more employees to provide 30 calendar days' advance written notice before a plant closing or mass layoff. This is significantly lower than the federal WARN Act's 100-employee threshold and 60-day notice period. Iowa Workforce Development provides Rapid Response Services for affected workers. Many businesses in the 25 to 100 employee range are subject to Iowa WARN but not federal WARN.
Iowa mini-COBRA (Ch. 509B)
Iowa Code Chapter 509B provides continuation of insured group health coverage, which matters most for groups below federal COBRA's 20-employee threshold. Duration is up to 9 months (compared to federal COBRA at 18 months). The employee must have been covered for the entire 3 months immediately preceding the termination.
The election window is short. Under §509B.3 the employee must request continuation in writing within 10 days of the later of the termination or the date they were given notice of the right, and even with proper notice the election cannot be made more than 31 days after termination.
Section 509B.5 gives the employer 10 days from termination to send the written notice, in person or by mail to the last known address. Because the employee's 10 days run from the later of termination or notice, a late notice moves the election deadline rather than closing it, and the 31-day cap applies only once proper notice has been given. A missed notice does not forfeit the right: the statute bars denying continuation for lack of proper notice. Contributions are paid monthly in advance to the employer or policyholder, at no more than the group rate.
Payroll Tax and UI Compliance
Iowa payroll registration requires separate registrations with the Iowa Department of Revenue for withholding and Iowa Workforce Development for unemployment insurance (UI). Both require a federal employer identification number (FEIN). The department's withholding guidance is at revenue.iowa.gov.
Iowa income tax: a flat 3.8% rate
SF 2442 (signed May 2024) accelerated Iowa's income tax reform, taking a flat 3.8% rate into effect on January 1, 2025, one year ahead of the schedule in HF 2317 and at a rate 0.1 percentage points lower than HF 2317 had planned. The Department of Revenue confirmed the same 3.8% rate for tax year 2026, applying to every level of taxable individual income.
Withholding runs on Iowa's own certificate. Use the IA W-4 (Form 44-019) for state withholding, and pull the current tables from the department rather than reusing a prior year's. Iowa inheritance tax was fully repealed effective January 1, 2025.
Unemployment insurance after the SF 607 reform
| Parameter | 2025 (pre-SF 607) | 2026 and 2027 (post-SF 607) |
|---|---|---|
| Taxable wage base | $39,500 | $21,100 from January 1, 2027 ($20,400 through December 31, 2026), about half the 2025 base under SF 607 |
| Rate tables | Table 8 (lowest) | Table D (lowest); 4 tables total (A to D) |
| Rate range | 0% to 7.0% (Table 8) | 0.000% to 5.400% |
| Max rate | 9.0% (highest in any table) | 5.4% |
| New non-construction employer rate | ~1.0% | Rank 4 of the table, floor 1.000% |
| New construction employer rate | ~7% | Rank 9 of the table, 5.400% |
SF 607 (signed June 5, 2025, effective July 1, 2025) cut the taxable wage base formula from 66.7% to 33.3% of the average annual wage. The base, $39,500 in 2025, is $21,100 from January 1, 2027 ($20,400 through December 31, 2026), according to Iowa Workforce Development's June 2026 announcement. The Legislative Services Agency fiscal note estimates the reform cuts employer contributions by about $1.18 billion over calendar years 2026 through 2030.
Contribution rates for calendar year 2026 come from Table D, the lowest the law allows, running 0.000% to 5.400% across nine benefit-ratio ranks, and the trust fund review triggered Table D again for 2027. Register with Iowa Workforce Development and keep the UI account current.
On the benefit side, Iowa Workforce Development raised the maximum weekly benefit to $790 (for a claimant with four dependents; $644 with none) for fiscal year 2027, effective the benefit week of July 5, 2026, up from $763.
Building an Iowa-Compliant Employee Handbook
Iowa does not require a written employee handbook, but once policies are established they become enforceable obligations. The implied contract exception to at-will employment means handbook language without a conspicuous at-will disclaimer can create contractual job security claims.
Some Iowa-specific handbook elements are required and others strongly recommended. Place an at-will disclaimer prominently near the beginning of the handbook. Add an ICRA anti-discrimination and harassment policy updated for SF 418 changes (gender identity removed, sexual orientation retained) for employers with 4 or more employees, plus a workers' compensation notice with coverage information and the injury reporting procedure.
Pay and testing policies come next: a drug and alcohol testing policy satisfying all §730.5 written policy requirements if the employer tests, and an Iowa WPCL rights notice covering pay frequency, paydays, and deduction practices.
Leave and benefits policies round out the handbook: pregnancy leave providing up to 8 weeks unpaid leave for employers with 4 or more employees (§216.6(2)(e)); voting leave (paid time to bring the employee to 2 consecutive hours, written request before Election Day); jury duty (unpaid but job-protected); military leave (§29A.43); and a mini-COBRA continuation notice procedure for insured group health plans.
Iowa Cities and Local Compliance
Iowa's HF 295 (signed March 30, 2017) is one of the broadest state employment preemption laws in the country. Iowa Code §331.304(12) for counties and §364.3(12) for cities prohibit all local ordinances on minimum wage, employment leave, hiring practices, employment benefits, scheduling, and any other terms or conditions of employment. County minimum wage ordinances adopted before signing became void and unenforceable on March 30, 2017, reverting those wages to $7.25 per hour.
The Iowa Supreme Court's ABI v. City of Waterloo (2021) decision carved out a narrow exception: cities may regulate the timing of criminal history inquiries but not the substance of what history employers may consider. Waterloo's fair chance hiring ordinance, which reaches employers with 15 or more employees for pre-offer inquiries, survived on those timing grounds.
Iowa Code §216.19 still lets cities prohibit broader or different categories of discrimination than the state act, so some local human rights ordinances may continue to list gender identity. How those local protections hold up after SF 418 and under HF 295 preemption is unsettled, so if your city has such an ordinance, check with counsel.
Iowa vs. Federal vs. Illinois
Iowa sits below Illinois on almost every employer obligation. The exceptions that trip employers up are the WARN headcount threshold and the wage recovery penalties. Illinois is the useful comparison because so many employers run staff across the Mississippi and assume one rulebook covers both.
| Parameter | Iowa | Federal | Illinois |
|---|---|---|---|
| Anti-discrimination threshold | 4 employees (ICRA) | 15 (Title VII); 20 (ADEA) | 1 employee (IHRA) |
| Minimum wage | $7.25/hr (since 2008) | $7.25/hr | $15.00/hr |
| Tipped minimum | $4.35/hr (40% tip credit cap) | $2.13/hr ($5.12 tip credit, about 71% of the wage) | $9.00/hr (60% of MW, 40% tip credit cap) |
| State income tax | 3.8% flat (2025 and 2026) | Federal brackets | 4.95% flat |
| Paid leave mandate | None | None federal | IL PLAWA: 40 hrs/year (2024) |
| State family leave | None private | FMLA (50+) | No general FMLA equivalent; VESSA leave from the first employee |
| OSHA | State plan (IOSHA) | Federal OSHA | Federal OSHA |
| WARN threshold | 25 employees / 30 days | 100 / 60 days | 75 / 60 days (IL WARN) |
| Right-to-work | Yes (since 1947) | N/A | No |
| Mini-COBRA | Insured group policies, 9 months | COBRA: 20+, 18 months | Insured group policies, 12 months |
| Pay transparency | None | None | Required in postings (IL HB 3129) |
| New hire reporting | 15 days | 20 days (federal default) | 20 days |
| Ban-the-box | Local only (Waterloo) | None federal | Statewide (JOQAA) |
| Drug testing law | §730.5 (detailed procedures) | Drug-Free Workplace Act | IL Cannabis Regulation and Tax Act |
The gaps that change a payroll or a policy are the anti-discrimination threshold (Iowa 4 employees against Illinois 1), the minimum wage ($7.25 against $15.00), the paid leave mandate (none in Iowa against 40 hours a year for every Illinois employer), and the WARN threshold (25 employees and 30 days against 75 and 60).
Union rules are where the one-rulebook assumption fails most plainly. Iowa is a right-to-work state and Illinois is not, so a union security clause (a contract term requiring union membership or dues) that is unenforceable at an Iowa location is ordinary at an Illinois one.
Iowa Employment Law Legislative Timeline
The timeline explains why older handbooks and checklists go stale in Iowa. Your next step is short: check your headcount against the ICRA and WARN thresholds, confirm your paydays and final pay practices meet the WPCL, set up state withholding and new hire reporting for every hire, and put the handbook policies above in writing.
Frequently Asked Questions
Does Iowa require E-Verify for private employers?
No. It is voluntary for private employers. Executive Order 15, signed October 8, 2025, aims at the state: departments verify employment eligibility before hiring state employees and verify immigration status or citizenship before granting state occupational and professional licenses. Iowa Code §91C is construction contractor registration, not E-Verify.
What is the Iowa minimum wage?
$7.25/hr, unchanged since 2008, and the federal rate governs if Congress raises it. Iowa allows an initial employment wage of $6.35/hr for the first 90 calendar days, but an FLSA-covered employer may use it only for hires under 20 (the federal youth wage); others must get $7.25. No city can set a higher local rate (HF 295, 2017).
Does the Iowa Civil Rights Act apply to my 5-person business?
Yes. The ICRA threshold is 4 employees, with family members excluded from the count. It covers race, sex, age (18+), disability, sexual orientation, and other classes. Gender identity was removed July 1, 2025.
When must I send an employee's final paycheck in Iowa?
By the next regular payday, for both discharge and voluntary quit (§91A.4). Commission wages: 30 days. Intentional nonpayment draws WPCL liquidated damages of 5%/day after a 7-day grace period, capped at 1× wages, and attorney fees are mandatory for a prevailing employee.
Does Iowa have its own OSHA program?
Yes. Private employers answer to Iowa OSHA (IOSHA), not federal OSHA: it has been a state plan covering the private and public sectors since 1973. Federal OSHA covers only federal operations, USPS, maritime, and certain interstate bridge work in Iowa.
Is gender identity still a protected class in Iowa?
Not under ICRA since July 1, 2025 (SF 418). Sexual orientation remains protected. Federal Title VII covers gender identity for 15+ employers under Bostock (2020).
What are Iowa drug testing requirements?
Testing is voluntary, but an employer that tests needs a written policy satisfying §730.5 (not "Chapter 730A," which does not exist). Split specimen testing, SAMHSA-certified lab confirmation, and employee retest rights within 7 days are required.
Is Iowa an at-will employment state?
Yes. Either party can end the job at any time without giving a reason. Three limits apply: the public policy exception, an implied contract created by handbook language with no conspicuous at-will disclaimer, and the anti-discrimination and anti-retaliation statutes, which in Iowa start at 4 employees.
