Series EE bonds mature after 30 years, meaning they can earn interest for that period of time. EE bonds are sold for half of face value and the U.S. Treasury Department guarantees they will reach face value after 20 years. Bonds must be owned for at least one year before redemption.
Tomâs response. It depends on what you mean by maturity. Final maturity â when they stop earning interest â is 30 years after the issue date for all Series EE and I Savings Bonds, as well as for all Series E bonds that are still earning interest. For Series HH and H Savings Bonds, final maturity comes after 20 years. Series EE bonds also have an original maturity date â when they will be worth at least double your original investment. Series I, H, and HH bonds are all sold at face value and donât have this feature.
