Increasing defined benefit accrual for specified years of service in the state retirement systems.

HB 1790 increases retirement benefits for Washington state employees in multiple retirement systems (including those for public employees, teachers, and law enforcement). It adds an extra 0.5% of an employee's average final salary per year for service beyond 30 years, effective for future service. This applies specifically to employees who reach 30+ years of service after the bill takes effect. The change modifies existing retirement formulas in statutes covering various state retirement plans (RCW 41.32.760, 41.32.840, 41.35.400, 41.35.620, 41.40.620, and 41.40.790).
