Insurance Letter 538


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 2021 "first closed" claims was $313,465,586. The Worker’s Compensation Division’s (WCD) net operating revenue to be collected for State Fiscal Year (SFY) 2023 is $13,408,891.61. Based on the calculation ($13,408,891.61 divided by $313,465,586), the general assessment rate is 4.278%. The general assessment rate was calculated using three decimal places rounded up to provide an accurate rate.

Self-insured employers pay the 4.278% general assessment rate plus an additional 1.245% to cover administrative costs of operating the self-insured employers program for a total of 5.523%. The self-insured employer invoice also includes the $200 self-insured renewal fee for the period of July 1, 2022 through June 30, 2023.

Each company's assessment amount is determined by multiplying its 2021 "first closed" claims' total indemnity payments by the rate indicated. Each company's claim detail listing is available online; click on Assessment Reports. You will need your DWD/WISCONSIN Logon Account ID and password.

In addition to funding standard operating expenses, this year's General Assessment includes $500,000 pursuant to Statute 102.81(1)(c), which requires the Department to transfer funds to the Uninsured Employer's Fund (UEF) for any UEF claims in excess of $1,000,000. Section 102.81 (1) (c), was created by 2015 Wis. Act 55, effective Jan. 1, 2016. This is the first year in which a UEF claim was determined to meet the criteria under the law. The law caps the total transfer at $500,000 in a calendar year.
