This bill would update federal rules for retirement plans offered by schools, charities, and nonprofit organizations. Right now, these 403(b) retirement plans have fewer investment options compared to 401(k) plans that many private companies offer. This bill would let 403(b) plans access more types of investment funds, similar to those available to private sector workers, as long as an employer or responsible party checks and approves the options. The aim is to give employees more ways to grow their retirement savings and possibly reduce fees, while still making sure their interests are protected.
