Beginning Rates

New employers begin at a standard rate depending on the type of business activity. For rate year 2020the rate consists of only the base rate. There are no surcharges in effect for 2020. However, between 2004-2012, the standard rate consisted of three components: a base rate, a solvency surcharge and a surtax. For the years 2013 through 2017, the standard rate consisted of two components: a base rate and a bond principal rate.

Employers in construction-related industries may be subject to a different base rate. The surcharges are the same, though. Contact UI Employer Services for more information on beginning base rates for employers in construction-related industries.
