When Do Savings Bonds Mature?

“Maturity” trips people up because savings bonds have two different milestones:

Final maturity by series

After final maturity

The bond's value is frozen. Every month you keep holding it, inflation erodes real value, and the IRS technically expects the accumulated interest to be reported in the year of final maturity even if you haven't cashed the bond — a rule that surprises many estates. The practical move: identify matured bonds, cash them, and reinvest.
