Washington Application for Group Retrospective Rating (WAR) is a program offered by the Washington State Department of Labor and Industries (L&I) that provides a discount or rebate to employers who purchase workers' compensation insurance through the L&I program. WAR allows employers to receive a discount on their workers' compensation premium based on their claims history. The WAR program is available to employers with at least 25 employees or a total annual payroll of $500,000 or more. There are two types of Washington Application for Group Retrospective Rating: Experience Rating and Transitional Rating. Experience Rating is a program that rewards employers for good safety records. Employers must have a three-year history of safe workplace practices, as well as a three-year history of claims and losses. The employer's premium rate is determined by their claims experience over the three-year period. Transitional Rating is a program that helps employers transition to the WAR program. Employers who have not been in business for three years or do not have three years of claim history can use Transitional Rating to get a discounted premium rate. The premium rate is determined by the employer's estimated future claims experience. Overall, the WAR program helps employers reduce costs by rewarding them for having a good safety record and helping them transition to the program.
