Retro Program Rules

The rules governing Retrospective Rating can be found in the Washington Administrative Code (WAC):

2023 Rulemaking - Insurance Tables Updates

The Retrospective Rating Program (Retro) is undertaking rulemaking to update its insurance tables in accordance with WAC 296-17B-010. The intent of the insurance table review is to ensure fairness and equity in the distribution of retrospective rating adjustments. The last update to Retro’s insurance tables occurred in 2017.

The L&I actuaries have completed their review of the insurance tables which have subsequently been independently reviewed by an outside actuarial firm, Oliver Wyman.

This current rulemaking has an anticipated effective date of October 1, 2023.
