Public retirement-actuarially determined contributions.

HB 83 requires Wyoming's public employee retirement system to calculate both employee and employer contribution rates using actuarial methods starting in 2027, replacing fixed percentages. Employees must pay 49.68% of the calculated rate, while employers (excluding firefighter entities) pay 50.32%, based on the system's actuarial valuation of retirement account assets and benefits. The bill mandates annual reports to state officials and local governments by April 15 each year, with contribution rates allowed to change by no more than ±0.5% annually. This directly affects all public employees and employers participating in Wyoming's retirement plan, including state agencies and school districts funded through education grants.
