The Scale of the Problem Is Larger Than Most People Realize
The numbers here are not estimates drawn from surveys or extrapolations. They come from official Treasury data. Treasury reported $35.1 billion in matured, unredeemed savings securities as of July 31, 2026, and that total has grown steadily from $7.8 billion back in January 2001. The trend has been moving in one direction for more than two decades, and it shows little sign of reversing on its own.
The U.S. Department of the Treasury is holding approximately 80 million matured U.S. savings bonds. Many of the people who purchased them, or who inherited them from a parent or grandparent, simply do not know these bonds exist or have long forgotten their exact details. The money is still legally theirs, but it is sitting idle.
Savings Bonds Do Not Earn Interest Forever
One of the most persistent misconceptions about savings bonds is that they just keep growing. They do not. One of the biggest misconceptions is that savings bonds continue growing forever. Most Series EE and Series I savings bonds earn interest for up to 30 years before reaching final maturity. Once that point arrives, the bond stops growing entirely, even though it still retains its redemption value.
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. The date is printed right on the face of the paper certificate, though most holders never think to check it against a calendar.
Which Series Have Already Gone Completely Silent
All Series E savings bonds have matured and stopped earning interest. Series EE bonds issued from January 1980 through May 1994 are no longer earning interest. These represent a substantial share of the paper bonds still held in American households today.
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. For holders of any of these series, there is no longer a reason to wait. The bonds have reached their ceiling.
Year 30 Arrives Quietly, With No Warning From Treasury
The thing that makes this problem so persistent is the absence of any notification system. When savings bonds reach final maturity and cease earning interest, the Bureau does not notify the bondholder. For those fully matured bonds remaining unredeemed, there is no active program by the Bureau to locate the bondholders and pay them.
A Series EE bond purchased in 1995 hit its 30-year mark in 2025. That bond no longer accrues a single cent of additional interest. Holders who tucked certificates into a safe deposit box decades ago and forgot about them are now losing the time value of that money every month they wait to redeem. There is no alarm. No letter. No email. The bond simply goes quiet.
The Tax Trap That Catches Heirs Off Guard
The financial silence of a matured bond is one problem. The tax implications are another. 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.
This means that if a bond matured in 2020 and the holder never cashed it, the accumulated interest from decades of growth technically became reportable income in 2020 – not whenever the holder eventually gets around to redeeming it. If the bond has reached final maturity, Treasury’s rule makes deferred interest reportable in the final-maturity year even if the bond is never cashed. Heirs who inherit old bonds and are unaware of this rule can find themselves facing an unexpected tax situation.
The answer is usually yes – but only federal income tax, and only on the interest, never on the original principal. The interest on Series EE and Series I U.S. savings bonds is federally taxable, but it is completely exempt from state and local income tax.
The Paper Bond Era That Created This Backlog
To understand why so many bonds have been forgotten, it helps to know when they were issued and how. The bonds were issued on paper until 2002, when the government launched electronic versions that redeem automatically at maturity. The government stopped issuing paper bonds altogether in 2014. That means every bond still sitting in a drawer today is almost certainly a paper certificate from a different era, one that required the holder to take action.
Most savings bonds accrue interest until maturing over a 20- to 40-year time period. When these bonds mature and cease to pay interest, it has been up to the buyer to remember to redeem the matured bond decades after the initial purchase. Expecting someone to track a paper instrument for 30 or 40 years, across moves and estates and generations, is a tall order. Many people simply did not manage it.
Congress Has Pushed Back, Legislating a Path to Recovery
The sheer scale of unredeemed bonds has drawn attention from lawmakers on both sides of the aisle. In June 2024, Representatives Sean Casten and Ann Wagner led 23 of their colleagues in a bipartisan letter urging the Department of Treasury to collaborate with states to return the more than $30 billion that the Treasury currently holds in unclaimed savings bond assets to bondholders.
The Unclaimed Savings Bond Act became law as part of the annual federal funding bill. This will help Americans claim over $29 billion in matured, unredeemed savings bonds currently held by the U.S. Treasury, including an estimated $215 million belonging to Mississippians. Under the new framework, Treasury is required to provide states with information about matured and unclaimed bonds so the states can use unclaimed property programs to help find the owners or heirs of the original owners and help them redeem their assets.
Treasury Hunt Is Gone – Here Is What Replaced It
For years, the primary tool for finding lost or matured bonds was a website called Treasury Hunt. That option is no longer available. The USDT previously had a Treasury Hunt website for people to find and claim unredeemed or matured Treasury securities. It was shut down on September 30, 2025, as part of the SECURE Act 2.0, which improved the search capabilities for consumers, with the USDT sharing bond information with state unclaimed property divisions to help citizens find and redeem matured securities.
The transition means that the search process now runs primarily through state-level programs. The National Association of Unclaimed Property Administrators (NAUPA) is an affiliate of the National Association of State Treasurers, covering unclaimed property programs for all 50 states, the District of Columbia, and the Commonwealth of Puerto Rico, as well as several foreign jurisdictions. The organization works to reunite unclaimed assets with rightful owners. Checking your state’s unclaimed property database at MissingMoney.com or your individual state treasury website is now the first practical step.
How to Redeem a Matured Paper Bond Today
Matured savings bonds do not expire: they stop earning interest at final maturity but remain redeemable at full value. That is worth repeating. The bond still has monetary worth, even if it stopped growing years ago. The accumulated value is fully accessible.
For paper bonds, the redemption process goes through a financial institution or directly through the Treasury. 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. For larger redemptions, submitting bonds directly to Treasury Retail Securities Services is the more reliable route. After you cash a bond, you’ll receive IRS Form 1099-INT showing the total taxable interest. If a bank processes the redemption, the 1099-INT comes from that bank, typically by January 31 of the following year.
The Quiet Cost of Doing Nothing
There is a real financial cost to leaving a matured bond untouched, beyond the obvious fact that it is no longer growing. Once a bond reaches year 30, it stops accruing interest and can generate a tax bill you never saw coming. Meanwhile, the purchasing power of that frozen sum erodes with every passing year of inflation.
Savings bonds that have reached final maturity no longer earn interest, so every day they sit unredeemed is a day your money does nothing. The proceeds could be reinvested, placed in a higher-yield account, or used for qualified education expenses, which can potentially reduce the federal tax burden on the interest under IRC Section 135. In Fiscal Year 2023 alone, NAUPA returned over $5 billion to rightful owners. The mechanisms to claim that money are there. The only remaining variable is whether holders choose to use them.
The Takeaway
A savings bond that stopped earning interest in 2010 or 2018 or even last year is not lost money, but it is money going to waste. The Treasury is not going to call. There is no automatic payout. The entire system, by design, requires the holder to act.
The good news is that the legislative and administrative landscape has shifted in recent years, making it somewhat easier for individuals and heirs to trace what they own. Checking your state’s unclaimed property database, reviewing any old paper certificates against their issue dates, and consulting the TreasuryDirect savings bond calculator are all concrete, free steps. The bonds are patient. Whether their owners remain patient to the point of never cashing them is the only real question left.
