"AARP strongly urges the Department to permit savers to maintain their My RA accounts after achieving $15,000 or 30 years of savings.... [A]lternatively, Treasury should consider offering or transferring accounts to a similar Government program, such as its inflation protected TIPS or I-Bonds.... Another program addition we recommend would be to permit and encourage employer plan cash-outs of small accounts (under $5000) into a MyRA.... Treasury must ensure strong spousal, beneficiary and other protections ... Key consumer protections ... should be provided to all MyRA account holders."
