The Wisconsin Compensation Rating Bureau (Bureau) is responsible for establishing, maintaining and administering rules, regulations, classifications, rates and rating plans to govern the transaction of worker's compensation insurance in Wisconsin. The Bureau files with OCI, on behalf of its members every manual of classifications, rules and rates, every rating plan and every modification of any of them proposed for use in this state. Insurance companies writing worker's insurance may not deviate from the approved rates and rating plans.

The approved rates and minimum premium for the last ten years for each classification code is located on the Bureau's web site at https://www.wcrb.org/WCRB/wcrbhome.htm. The rate for each classification code is the amount of premium for each $100 in remuneration provided by an employer to his or her employees. The minimum premium for each classification code is the lowest premium required in order to provide worker's compensation insurance.

The classification code or codes applicable to a business may be found on the declarations page of the employer's worker's compensation insurance policy. For additional information on the classification system used for worker's compensation insurance, please refer to our Consumer's Guide to Worker's Compensation Insurance For Employers.
