First, check to see whether they are still earning interest. If not, cash them in and invest the money somewhere else. iStockphoto By Kimberly Lankford, Contributing Editor April 19, 2017 QMy parents and grandparents gave me some savings bonds when I was born. How can I figure out if they’re still earning interest? If they aren’t earning interest anymore, how do I cash them in?AThe maturity date depends on the type of savings bond and when it was issued. Most savings bonds earn interest for 30 years, although HH bonds earn interest for 20 years, and old Series E bonds (from November 1965 and earlier) earn interest for 40 years. If you have E bonds or H bonds, they aren’t earning interest anymore; neither are EE bonds issued from January 1980 through April 1987 or HH bonds issued from January 1980 through April 1997. See the full list by date at TreasuryDirect.

If you discover that your savings bonds have matured, you should cash them in and invest the money elsewhere. If you have paper bonds, contact your bank to see if it cashes savings bonds (not all banks do, and some will cash in savings bonds only for customers who have had accounts for at least six months). For more information, see How to Cash in Savings Bonds. Advertisement If you have Series E, EE or I bonds, another option is to use the Smart Exchange at TreasuryDirect to convert your paper savings bonds to electronic bonds, which will make them much easier to monitor and redeem (you can link your TreasuryDirect account to a bank account). For more information, see Converting Paper Savings Bonds to Electronic Form. If you can’t locate a paper bond, you can fill out Form 1048, Claim for Lost, Stolen or Destroyed U.S. Savings Bonds, and the Treasury will search its records. Provide your name and Social Security number (and the purchaser’s Social Security number, if the bond was received as a gift), the approximate issue date (or at least a range of years), the serial number, if available, and any other information you may have, such as the bond series or denomination. If you don’t have all of this information, fill out as much as you can. Get the form certified by a financial institution, and send it to the address listed on the form for the type of bond you’re trying to track down.
