U.S. Savings Bond Series

U.S. savings bond series, including Series EE and Series I bonds, with different accrual, redemption, and tax features.

U.S. savings bond series are retail Treasury programs with program-specific interest, redemption, tax, and ownership rules. The series label matters because Series I Bonds, Series EE Bonds, and older discontinued series do not behave the same way.

Use this branch when the question is how a U.S. savings bond earns interest, when it can be redeemed, whether it is still issued, and how the owner should verify official Treasury rules. These pages are educational and should not be read as individualized savings, tax, or investment advice.

For inflation-linked retail savings bonds, start with Series I Bond. For marketable inflation-linked Treasury securities, compare with Treasury Inflation-Protected Securities.
