Insurance Letter 532


To communicate to insurance carriers and self-insured employers the new assessment rate. This includes information regarding deadlines and reminds insurance carriers and self-insured employers that interest will accrue on all unpaid balances after 30 days. The Worker’s Compensation Administrative Assessment is issued annually.


Section 102.75, Wis. Stats., authorizes the department to assess and collect the administrative costs for the Wisconsin Worker’s Compensation Act from worker’s compensation insurance carriers and self-insured employers. Each company's indemnity amount is determined by summing the amounts paid for each claim "first closed" in the previous calendar year. Indemnity includes payments for temporary total and partial disability, permanent total and partial disability, compromises, death benefits and funeral expenses, paid holidays, supplemental benefits, disfigurement, and vocational rehabilitation.

The Worker’s Compensation Administrative Assessment rate is calculated by dividing the current state fiscal year’s operating costs by the total indemnity payments from carriers and self-insured employers for claims "first closed" in the previous calendar year. The total indemnity paid for 2020 "first closed" claims was $215,614,166. The Worker’s Compensation Division’s (WCD) net operating revenue to be collected for State Fiscal Year (SFY) 2022 is $12,804,550. Based on the calculation ($12,804,550 divided by $215,614,166), the general assessment rate is 5.939%. The resulting rate is rounded up to avoid a budget shortfall.

Self-insured employers pay the 5.939% general assessment rate plus an additional 1.755% to cover administrative costs of operating the self-insured employers program for a total of 7.694%. The self-insured employer invoice also includes the $200 self-insured renewal fee for the period of July 1, 2021 through June 30, 2022.

Each company's assessment amount is determined by multiplying its 2020 "first closed" claims' total indemnity payments by the rate indicated. Each company's claim detail listing is available at Administrative Assessments; click on Assessment Reports. You will need your DWD/WISCONSIN Logon Account ID and password.
