BULLETIN NO. 21-06
DATE: September 17, 2021
TO:
Insurers writing workers compensation insurance in Idaho
FROM: Dean L. Cameron, Director
SUBJECT: Guidance regarding certain workers compensation rate parameters as a
result of House Bill 78
This bulletin to insurers issuing workers compensation policies provides guidance from the
Idaho Department of Insurance (the “Department”) concerning rating changes to policies
issued or renewed in Idaho on or after January 1, 2022.
House Bill 78, signed by Governor Little on March 12, 2021, revised key provisions of Idaho
Code § 41-1612 Worker’s Compensation Rates – Adherence to Filings, which becomes
effective January 1, 2022. The bill removed mandated minimum premium provisions for
policies as well as removing a fixed payroll amount for rating sole proprietors or partners when
they have elected coverage.
The Department has worked with the National Council of Compensation Insurance (NCCI) to
evaluate the impacts of these changes on the workers compensation market in Idaho. From
those discussions, the Department has established the following guidance for the NCCI to
utilize in their annual filing.
Minimum premium
The minimum premium is not to exceed $400.
Expense constant
The expense constant is to be $100 for every policy. This replaces a lower bound on the
minimum premium.
Payroll to be used when rating sole proprietors and partners who have elected coverage
The payroll is to be equal to 50% of the Average Weekly Wage (AWW), as determined by the
Idaho Department of Labor. The 2021 AWW for Idaho is $842.00, and the 2022 AWW is not
yet released.
