The maturity date for retirement savings bonds is indeterminate and may be different for each bond issued, but shall not exceed the sum of an original maturity period of 20 years and an extended maturity period of 10 years. The retirement savings bond purchased by the designated Roth IRA custodian on behalf of a program participant will mature at the earlier of 30 years from the date the bond is first issued to the custodian on behalf of the program participant or when the total value of the bond held on behalf of the program participant reaches $15,000.00. The designated Roth IRA custodian will submit a request for redemption of retirement savings bonds upon maturity.
