What happens if I move from one state to another?
You have a choice of leaving your money in the existing plan or rolling it over into the plan of your new state. Assets of one 529 plan can be transferred tax-free to another 529 plan for the same beneficiary once during a 12-month period. There may, however, be state tax implications when you transfer from one 529 plan to another. Also, if you decide against changing plans after moving, you may lose any state tax deduction on future contributions and state tax exemptions on withdrawals made to the plan offered by your former home state. (The money invested will still grow tax-deferred.) Your new state also may offer favorable tax treatment for investments made in its plan. As a result, when moving, you should investigate the tax implications of each state's plans. An account owner does have the option of establishing accounts in more than one state for the same beneficiary.

Where can I find more information on 529 plans?
Many mutual fund company websites provide information on education savings programs they offer. Individuals seeking additional information on prepaid tuition plans and college savings plans may want to visit the website of the College Savings Plans Network, an affiliate of the National Association of State Treasurers, at www.collegesavings.org. Additional information about 529 plans and their regulation is available through the websites of the Municipal Securities Rulemaking Board (www.msrb.org), which regulates the offer and sale of such plans, and of the NASDR (www.nasdr.org), which regulates broker-dealers.
