The U.S. Treasury recommends cashing all savings bonds that have reached final maturity because that is when they stop earning interest. However, the Treasury has extended original maturity dates from 10 to 30 years, making it harder to know when final maturity occurs. Additionally, different issues and series have different earning lifetimes. However, the Treasury supplies a number of guidelines and tools to facilitate your calculation of the final maturity date.

Collect all series A, B, C, D, F, G, J and K paper bonds. These old bonds have all reached final maturity and have stopped earning interest.

Set aside all series E and H bonds. They have reached final maturity.

Examine the issue date on the paper HH bonds. Add 20 years to the issue date to determine the date of final maturity.

Check the issue date of the paper EE bonds. Add 30 years to the issue date to determine the final maturity for the EE bonds.

Check the issue date of the paper I bonds. The final maturity of the I bonds is 30 years from the date of issue.

Log onto your Treasury Direct account to find the final maturity date of your electronic EE and I bonds. Enter your secure password to access complete information on your electronic portfolio, including maturity date and interest earnings.
