Iowa business insurance: requirements and costs

Iowa requires workers' comp from an employer with a single covered employee, with no headcount threshold,⁠4⁠8 and a willful, knowing failure to insure is a class D felony.⁠7 Premiums come from private insurers using NCCI's advisory rates. NCCI filed an average -2.5% for January 1, 2026 and a further -2.1% for January 1, 2027.⁠1⁠2 Iowa has no state fund and no statutory disability or paid-leave program.

Iowa Code ch. 85 applies to employers unless an exclusion in s. 85.1 removes the worker. The exclusions are narrow: household help and casual workers who earn less than $1,500 from the employer in the prior 12 months, and farm workers where the employer's prior-year cash payroll to non-exempt workers was under $2,500 (family members of the farm operator stay excluded regardless).⁠4 Section 87.1 then requires every covered employer to insure the liability with an organization approved by the Commissioner of Insurance, or to qualify for relief such as an approved group self-insurance plan.⁠8⁠9 An uninsured employer who is asked for proof by the workers' compensation commissioner and cannot give it is liable for an injured worker's claim under the common law as modified by statute.⁠8 Owners are treated differently from staff. Proprietors, LLC members and partners are outside the system unless they elect coverage by buying a policy that names them, and those who do not elect must sign a written nonelection, and up to four officers of a corporation can sign a written rejection that is attached to the policy.⁠5⁠6

Prices are set by the market, anchored on NCCI. For January 1, 2026 NCCI filed an overall average change of -2.5% to both the voluntary advisory rate level and the assigned risk rate level, built on selected annual loss-ratio trends of -4.5% for indemnity and -3.5% for medical claims.⁠1 The Iowa Insurance Division lists an order for the January 1, 2026 effective date, and its August 2025 notice of the next filing describes the 2026 rates as the "current rates" that took effect that day; we could not read the order text, so we do not state an approved percentage.⁠2⁠3 For January 1, 2027 NCCI has filed -2.1%, with a trend selection of -4.0% for both indemnity and medical.⁠16 The same page shows no order for 2027 yet.⁠3 Any of these figures is an average for the state; your class code, experience modification and carrier's schedule rating decide your own bill.

The official cost data place Iowa slightly above the middle. NASI estimates Iowa employers paid $1.02 per $100 of covered wages for comp in 2023, against $1.22 in 2019, a 16% drop by our calculation, the same as the national fall from $1.17 to $0.98.⁠12 Oregon's 2024 ranking, built on manual rates in effect January 1, 2024, puts Iowa 19th most expensive of 51 jurisdictions at an index of $1.21 per $100 of payroll, 110% of the median. Neighbors Nebraska ($1.12) and South Dakota ($1.13) rank below it, while Minnesota ($1.25), Missouri ($1.31), Illinois ($1.34) and Wisconsin ($1.42) rank above.⁠13 Health coverage is the sharper constraint for small firms. AHRQ's 2025 survey found 30.7% of Iowa private-sector establishments in firms under 50 employees offered health insurance, against 32.1% nationally. Those that did offer it averaged $8,572 for single coverage, about 5% below the $9,034 small-firm national figure by our calculation, with the employee share at $2,150 against $1,924.⁠14

Iowa auto liability is fault-based and no PIP is required. A driver may not operate a vehicle on Iowa highways without financial liability coverage in effect and proof of it in the vehicle, and the statutory floor is the 20/40/15 set out in s. 321A.1.⁠10⁠11 That floor is a minimum, not a measure of what a contract or a serious injury claim will demand.

Workers’ compensation in Iowa

Every employer with an employee not excluded by s. 85.1 must insure its comp liability; there is no minimum number of employees.⁠4⁠8 Household workers and casual workers are covered once they earn $1,500 or more from the employer in the prior 12 months, and farm employers once prior-year cash payroll to non-exempt workers reaches $2,500.⁠4

Who is exempt

  • Household workers and purely casual workers earning under $1,500 from the employer in the 12 months before the injury (s. 85.1(1)-(2))
  • Agricultural workers where the employer's prior-year cash payroll to non-exempt workers was under $2,500; the farm operator's spouse, parents, siblings, children and stepchildren are excluded either way
  • Up to four corporate officers (president, vice president, secretary, treasurer) who knowingly and voluntarily sign a written rejection (ss. 85.1(5), 87.22); family farm corporations are carved out
  • Proprietors, LLC members, LLP members and partners are not covered unless they elect coverage under s. 85.1A

Buying coverage and who sets the rates

Employers buy from an insurer approved by the Commissioner of Insurance, or get relief through an approved group self-insurance plan.⁠8⁠9 Employers that cannot find a voluntary policy use the assigned risk market, whose rates NCCI files with the Iowa Insurance Division.⁠1

Groups of employers may form self-insurance associations under conditions set by the insurance commissioner, and the commissioner must approve each plan before it starts.⁠9

Penalties for going without

An employer subject to the comp chapters may not engage in business without insurance or approved relief. A person who does so willfully and knowingly commits a class D felony.⁠7 An employer that cannot show proof of coverage when the commissioner asks is liable for injuries under the common law as modified by statute.⁠8

Oregon’s biennial comparison of workers’ comp rates puts Iowa’s index for rates in effect on 1 January 2024 at $1.21 per $100 of payroll, 10% above the national median of $1.09 (rank 19 of 51, where 1 is the most expensive). The index prices the same 50 risk classes, weighted by Oregon payroll, in every state, so it compares rate levels rather than what employers actually pay. Compare every state.

Commercial auto in Iowa

Every vehicle registered in Iowa, including business vehicles, must carry at least 20/40/15 in liability limits (bodily injury per person / per accident / property damage, in thousands of dollars). Official source.

Iowa's definition of proof of financial responsibility is $20,000 for one person's injury or death, $40,000 for two or more people in one accident and $15,000 for property damage.⁠10 Drivers must have financial liability coverage in effect and carry proof in the vehicle.⁠11 No PIP requirement applies. The 2026 Iowa Code text keeps these limits.

Trucks and buses used in interstate commerce must also meet federal minimums of $750,000 to $5 million: see commercial auto minimums and what commercial auto costs.

Other Iowa rules that affect insurance costs

Owner and officer coverage is a choice you document

A sole proprietor, LLC member or partner is outside the comp law unless a policy specifically names them,⁠5 and one who does not elect coverage must sign a written nonelection attached to the policy (or witnessed and filed with the commissioner if no policy exists).⁠6 A corporate officer who rejects coverage must sign a written rejection attached to the policy, or witnessed by two disinterested people and filed with the workers' compensation commissioner if no policy exists; no more than four officers per corporation can opt out.⁠6 A contractor or lender that asks for proof of coverage on you as an owner will see this election in the policy.

Motor carriers and owner-operators

A motor carrier that contracts with an owner-operator acting as an independent contractor under s. 85.61(12)(c) need not insure its comp liability for that owner-operator, and may buy coverage and charge the owner-operator the premium. The carrier must require a certificate of comp coverage for the owner-operator's own employees.⁠8
