Contact the plan administrator that runs the 529 plan that you want to join. (All plans have websites and toll-free numbers to help you get the information you need.) Plan administrators may be state agencies or companies established solely for the purpose of running a 529 plan, or they may be investment firms. In any case, the plan administrator operates under the authority of each state government, such as the state treasury department. The plan administrator will send you a packet of information that includes enrollment materials, along with a program description. Read the information thoroughly and make sure you understand the plan’s rules before you enroll.
In addition, be sure to check the enrollment period for the plan. Many states offer open enrollment, meaning you can join the plan at any time. Other states have shortened enrollment periods, such as October to January.
Note: Investors should consider the investment objectives, risks, charges, and expenses associated with 529 plans before investing. More information about 529 plans is available in each issuer’s official statement, which should be read carefully before investing. Also, before investing, consider whether your state offers a 529 plan that provides residents with favorable state tax benefits.
