Employer coverage threshold — 4 employees
The Iowa Civil Rights Act applies to employers who regularly employ four or more individuals. For purposes of this threshold, individuals who are members of the employer's family are not counted as employees. This 4-employee minimum is lower than the 15-employee threshold under federal Title VII, meaning Iowa's discrimination protections reach some smaller employers not covered by federal law.

Protected classes under the Iowa Civil Rights Act — employment context
The Iowa Civil Rights Act prohibits employment discrimination based on age, race, creed, color, sex, sexual orientation, national origin, religion, and disability. Pregnancy discrimination is also prohibited. Gender identity, which had been a protected class since 2007, was removed from Chapter 216 effective July 1, 2025, and is no longer protected under state law. These protections apply to employers who regularly employ four or more individuals, a lower threshold than the 15-employee minimum under federal Title VII.

Complaint filing deadline — 300 days under Iowa Code § 216.15(13)
A person claiming discrimination under the Iowa Civil Rights Act must file a verified written complaint with the Iowa Office of Civil Rights within 300 days of the alleged discriminatory or unfair practice. Iowa Code § 216.15(13) states that a claim under the Act "shall not be maintained unless a complaint is filed with the [agency] within three hundred days after the alleged discriminatory or unfair practice occurred." This administrative filing is a mandatory prerequisite to any subsequent court action under Iowa Code § 216.16.
The 300-day deadline runs from the date of the discriminatory act itself, or in cases of continuing violations constituting a pattern or practice, from the most recent act within the pattern. Iowa Administrative Code § 161-3.2(1) provides that "all alleged continuous violations that constitute a pattern or practice are timely if the most recent act occurred within 300 days of filing the complaint." The filing period is subject to waiver, estoppel, and equitable tolling depending on the facts and circumstances of the case, which can suspend the running of the deadline. Iowa Admin. Code § 161-3.2(2).
Comparison to federal deadline. Iowa's 300-day requirement aligns with the extended federal EEOC deadline in deferral jurisdictions. Iowa and the EEOC maintain a work-sharing agreement, so filing with one agency and requesting cross-filing with the other is sufficient; dual filing is unnecessary. For employers with 4–14 employees (covered by Iowa but not federal Title VII), the complaint must be filed with the Iowa Office of Civil Rights, as federal law covers only employers with 15 or more employees.
Administrative exhaustion and right to sue. After filing with the agency, a complainant may request an "administrative release" (commonly called a right-to-sue letter) once the complaint has been on file for at least 60 days. Iowa Code § 216.16(2)(b) conditions the right to commence a district court action on the issuance of the release. The statute directs that the agency shall attempt at least a preliminary screen within the first 120 days. Iowa Code § 216.16(7).
Once the release is issued, a lawsuit in Iowa district court must be filed within 90 days of the release date. Iowa Code § 216.16(4) provides that "[a]n action authorized under this section is barred unless commenced within ninety days after issuance by the [agency] of a release under subsection 3." This is a strict statute of limitations; missing the 90-day window bars the claim. If a complainant obtains a release, the agency is barred from further action on that complaint. Iowa Code § 216.16(4).
Effective date of agency renaming. As of July 1, 2024, the Iowa Civil Rights Commission became administratively based within the Iowa Office of Civil Rights. The statutory references to "commission" in Iowa Code Chapter 216 remain unchanged as of the 2025 Code; practitioners should treat the terms interchangeably.
