Beginning Rates


New employers start paying UI premiums at a beginning rate depending on the type of business activity. For rate year 2024, the rate consists of the beginning rate, the support rate and the solvency surcharge rate.

New employers in construction-related industries may be subject to a different beginning rate. If solvency surcharges are in effect, those surcharges are the same. Contact UI Employer Services for more information on beginning rates for employers in construction-related industries.
