All public utilities subject to Iowa Code chapter 476 are required to file an annual report by April 1 that covers operations for the immediately preceding calendar year. Annual reports covering calendar year 2023 are to be filed in IUB 24/7, where companies will also review and edit their company profile and attest the information is up-to-date. See 199 Iowa Administrative Code (IAC) 23.1(2) for more information on filing requirements.

NOTE: 2023 Annual Report forms are now available; see below.

Gas, electric, and water utilities, and competitive natural gas pipeline companies:

Once the annual report is submitted in IUB 24/7 and a review of the report is completed, your report is shown as Accepted in the Company Record.

How to find your company number

The IUB has assigned a company number to each company in its database. To find that company number, run a Company Search from the IUB’s electronic filing system. On the Company Search page, fill in the company name and click on search. If you are not sure how the company name appears in the IUB database, you may search by industry type to get a list of all the companies in that industry. If the search results return more than one company, click on Summary next to your company. The company summary page will include the company number as part of the information about the company.
