Commercial cleaning and janitorial insurance in Iowa

Iowa's sales tax rule comes first, then registration and proof

Start with tax, because it changes how you register and how you bill. "Janitorial and building maintenance or cleaning" is one of the services Iowa Code 423.2(6) makes taxable, and the Iowa Department of Revenue lists it as a taxable service for non-residential buildings. You charge 6% state sales tax, plus the 1% local option tax where a county or city has adopted it.

The department's rule, 701—211.23 (in effect since August 28, 2024), counts floor cleaning, vacuuming, waxing, interior window washing and restroom cleaning as janitorial work. The key exemption: janitorial services and building maintenance or cleaning performed on, or in connection with, new construction, reconstruction, alteration, expansion or remodeling of a structure aren't taxed. Final cleanup on a builder's project can fall on the exempt side; nightly cleaning of the finished building doesn't. Confirm how a mixed job should be billed with the Iowa Department of Revenue or your CPA.

Registration

Form your entity with the Iowa Secretary of State, then register with the Department of Revenue for a sales tax permit and a withholding account. Iowa Code 423.36 bars furnishing taxable services without that permit. We found no state license for commercial cleaning as a trade, so the permit is the main state-level requirement. Public buyers check it: the Iowa Department of Health and Human Services' janitorial bid form asks for "proof of insurance and registration to do business in the state of Iowa."

We didn't find a general city business license in the major cities. Iowa cities also can't set their own minimum wage, leave or scheduling rules: Iowa Code 364.3(12) bars them, and conflicting ordinances adopted before March 30, 2017 became void on that date. Wage rules for your crews are the same in Sioux City as in Dubuque.

Schools

Iowa Code 279.69 makes districts check court records and the sex offender, child abuse and dependent adult abuse registries for school employees, a term that includes part-time, substitute and contract employees of the district. It doesn't spell out checks for an outside vendor's crew. Guidance for Iowa districts says they may extend checks to contractors on school grounds and may write the vendor's duty to run the checks, and to answer for damages, into the contract. Expect the requirement to come from the district's contract.

Iowa comp starts with your first cleaner

Iowa has no minimum headcount for comp. Every employer covered by the law must insure, or get approval to self-insure, before doing business (Iowa Code 87.1 and 87.14A).

• Class. NCCI files Iowa's comp rates, and contract janitorial payroll usually falls under Code 9014. Iowa uses advisory rates, not loss costs: NCCI's filing for January 1, 2026 lists 9014 at $1.958 per $100 of payroll, with a $375 minimum premium. Each carrier may adopt that rate or deviate from it.
• Owners. Proprietors, LLC members and partners aren't automatically covered. An owner who works in the business substantially full-time can choose coverage by buying a policy that specifically includes that owner (85.1A). A corporation's president, vice president, secretary and treasurer, up to four officers, can reject coverage in writing. The rejection is attached to the policy, or, with no policy, witnessed and filed with the Workers' Compensation Commissioner (87.22).
• Subs. Iowa's contractor registration law (Iowa Code 91C) is aimed at construction, and we found no janitorial 1099 test. Public buyers push comp down the chain anyway: the HHS janitorial solicitation requires the winning bidder "and any subcontractor" to carry comp and employer's liability as Iowa law requires.

Rejection and nonelection forms and a coverage lookup are on the Workers' Compensation Division page of Iowa's Department of Inspections, Appeals and Licensing.

What Iowa agencies and universities ask a cleaning contractor to carry

Iowa public buyers range widely. The HHS solicitation for twice-monthly janitorial service at its Carroll Child Support Services office (a one-year term from July 1, 2025, renewable for up to five more one-year terms) asked the bidder and any sub for:

• general liability on an occurrence basis, including contractual liability: $500,000 each occurrence and $500,000 for the general aggregate, products and completed operations, and personal injury
• auto liability of $500,000 combined single limit, covering any auto plus hired and non-owned
• $500,000 umbrella or excess, and $500,000 property damage
• comp and employer's liability as Iowa law requires, with proof of insurance and registration attached to the bid

Universities ask for more (see Iowa City and Ames below). None of these three documents lists a fidelity bond. When a client does add one, our janitorial bond guide explains how they work, and our contract requirements guide decodes the rest.

Iowa risks that catch cleaning companies off guard

Going without comp, even briefly

An uninsured Iowa employer sued by a hurt worker is presumed negligent and can't argue contributory negligence or assumption of risk (Iowa Code 87.21). Willfully and knowingly running without coverage is a class D felony (87.14A). Even a short lapse between policies leaves you uninsured for any injury in that gap.

Subs who don't match your coverage

The HHS bid and Iowa State's form expect every subcontractor to carry the same coverage you do; Iowa State also lets you cover subs under your own policy. If you hand overflow floor work or a post-construction cleanup to another crew, collect their certificates first. Our specialty cleaning page covers project cleanup work.

Iowa cities and their local wrinkles

Cost factors for Iowa cleaning companies

Iowa's sales tax is charged to your client, not paid out of your premium budget, but it raises the total price a facility manager compares across bids. On the insurance side, some GL policies are rated on your sales, so ask your agent whether the tax you collect should be left out of the sales figure you report. Comp is rated on payroll by class.

Your price depends on the payroll in each class code, your annual sales, the kinds of buildings you clean, how much specialty and chemical work you do, the vehicles your crews drive, your claims history and the limits your contracts require. Published ranges are in our cleaning business insurance cost guide.
