Somewhere in a drawer or shoebox, a savings bond from your parents may have quietly hit a wall years ago, stopped earning entirely, and already triggered a tax bill nobody filed. Here is how to find out if yours is…

If you inherited a shoebox of paper savings bonds from a parent or grandparent, some of them may have quietly stopped paying you years ago. U.S. savings bonds do not earn interest forever. They hit a hard stop called final maturity, and for the Series EE, Series I, and Series HH bonds most families still hold, that stop lands at exactly 30 years from the issue date printed on the face. Treasury’s Bureau of the Fiscal Service continues to report billions of dollars in matured, unredeemed savings bonds sitting in circulation. Once a bond reaches year 30, it stops accruing interest and can generate a tax bill you never saw coming.
Year 30 Is a Hard Wall
When a savings bond reaches final maturity, it stops earning interest. For Series EE bonds issued from 1980 onward, the final maturity point is 30 years from the issue date. Series I bonds, first offered in 1998, also reach final maturity at 30 years. Series HH bonds had a 20-year term, and the last ones still outstanding stopped earning interest in 2024. Older Series E bonds ran for either 30 or 40 years, depending on when they were issued, and the final Series E bonds stopped paying in 2010. If your bond is more than 30 years old, it is no longer earning anything.
Where the Rule Is Written
The maturity terms for savings bonds are in 31 CFR Parts 351, 359, and 360, the Treasury regulations governing Series EE, Series I, and legacy series. For the current earning period, the Series I composite rate is 4.26%, made up of a 0.9% fixed rate and a 1.67% semiannual inflation rate, applicable to bonds issued from May 1, 2026, through October 31, 2026. A bond past year 30 earns none of that.
Tax Trap Most Holders Miss
Most savings bond owners elect deferred reporting, meaning they do not pay federal income tax on the interest as it accrues each year. Under IRS Publication 550 and Internal Revenue Code Section 454, the deferred interest becomes taxable in the year the bond is cashed, or the year it reaches final maturity, whichever comes first. A bond that hit year 30 in 2022 already triggered a taxable event, even if nobody cashed it, and the interest should have been reported that year (it is one of several quiet IRS rules that drain retirement money without warning, and we mapped the rest in a free tax trap guide). Bring the bonds and dates to a CPA.
Who This Actually Affects
Paper savings bonds are basically a relic now. The Treasury stopped selling them at banks back in 2012, except for a small carve-out that lets people buy I bonds with their tax refund. The folks holding them today are almost always heirs, surviving spouses, or adult children clearing out a parent’s house. How the bond is titled makes all the difference. If it is in your parent’s name alone, it has to go through the estate. If it has a co-owner or a POD beneficiary listed, it transfers directly to that person and can usually be cashed in with just a death certificate.
Sequence to Run This Week
- Sort the bonds by series letter and issue date printed on the face. Anything older than 30 years is no longer earning.
- Run each serial number through Treasury Hunt at TreasuryDirect.gov, the official search tool for matured, unredeemed bonds.
- Use the TreasuryDirect Savings Bond Calculator to confirm the current value and whether interest is still accruing.
- Redeem paper bonds at your bank if you have an established account there. Banks may cap over-the-counter redemptions, often at $1,000 for non-customers. Larger amounts, inherited bonds, or estate redemptions go through FS Form 1522, mailed to the Treasury with a certified death certificate and notarized signatures.
- If any bonds are still earning and you have qualifying college costs, ask your CPA about the education interest exclusion under IRC Section 135, which has income phase-outs, filing-status restrictions, and requires the bond owner to have been at least 24 at issuance.
Opportunity Cost While You Delay
A matured bond earns nothing. The 10-year Treasury yield sits at 4.79% as of September 2, 2026; the FDIC national average 12-month CD pays 1.71% as of August 1, 2026; and the CPI reading of 332.8 for July 2026 keeps eroding the purchasing power of cash that is not working. The bond in the drawer is losing ground every month you leave it there.
