I bonds — when do they mature?

How long are you able to keep I bonds without having to cash them in and report interest like 30 years for series EE bonds

Terry Says:  You must cash in the I-bonds on their “final maturity date” — 30 years from the date of issue.  If you want specifics, go to the savings bond inventory valuation program at www.SavingsBonds.com, insert the date you purchased the bond and it will give you the final maturity date.  You can cash them early, but be sure to get a “cash-in” report from the same website, so you don’t miss out on an interest payment.
