Savings Bond Final Maturity

Final maturity is the end of a savings bond's interest-earning life: the date after which the bond's redemption value stops growing no matter how long it is held. For the two series Treasury sells today, Series EE and Series I, it falls 30 years after the issue date. The term is Treasury's own and appears in the savings bond regulations at 31 CFR part 353, where section 353.31(a) says interest on a Series HH bond "ceases at final maturity". How long the period runs depends on the series, and within one series it can depend on when the bond was issued, so the date has to be worked out from the certificate rather than assumed. Final maturity is also the point at which two separate things stop being true at once: the bond stops paying, and the deferral of federal income tax on the interest ends.

The interest-earning life is 30 years for both current series, and Treasury states it in the same words on both pages. Asked how long an EE bond earns interest, TreasuryDirect answers "30 years (unless you cash it before then)", and the I bond page gives the identical answer. IRS Publication 550 describes both series the same way, saying Series EE bonds "have a maturity period of 30 years" and that Series I bonds are "inflation-indexed bonds issued at face value with a maturity period of 30 years." The 20-year doubling guarantee that EE bonds carry is a separate feature about the rate rather than about the clock, and it belongs to the Series EE page.

Older series are all finished, and knowing which is which saves a pointless wait. Publication 550 states that all Series E bonds have matured and are no longer earning interest, that all Series H bonds have matured, and that all HH bonds reached final maturity and stopped earning interest in August 2024. TreasuryDirect's page on historical and retired bonds fills in the maturity periods behind those statements: Series A through D ran 10 years, Series F and G ran 12 years, and Series E ran 40 years for bonds issued from May 1941 through November 1965 and 30 years for those issued from December 1965 through June 1980. All of them are listed as no longer earning interest. So a certificate found in a drawer from any series other than EE or I is certainly done, and an EE bond issued more than 30 years ago is done too.

The tax rule is the reason the date matters even to someone in no hurry for the money. Publication 550 gives cash-method taxpayers two ways to report savings bond interest. Method 1: "Postpone reporting the interest until the earlier of the year you cash or dispose of the bonds or the year in which they mature." Method 2 is to report the annual increase in redemption value as interest each year. Most people use Method 1 by default, because the publication says that if you do not choose Method 2 you must use Method 1. Read the first method carefully and the trap is visible: the deferral ends at the earlier of two events, and maturity is one of them. Nobody has to cash anything for the interest to become reportable.

Treasury says the same thing in its own words, which is worth knowing because its main tax page appears to say something different. TreasuryDirect's page on tax information for EE and I bonds is answering the question of when the money arrives, and it answers correctly: "For a paper bond, this happens when you cash the bond. For an electronic bond, it happens either when you cash the bond or when the bond finishes its 30-year life." That is about receipt, not about reporting. On its HH bond page, where the point cannot be avoided, Treasury states the reporting rule directly: deferred interest on a 2004-dated HH bond "will be reportable in the 2024 tax year, even if you do not redeem your bond", and "the deferred interest is reportable to the IRS in the year it reaches final maturity or the year it's redeemed, whichever occurs first." The two agencies are answering two questions, and on the question of reporting they agree.

The gap between those two facts is this page's whole point, and it lands hardest on paper. An electronic bond is redeemed by Treasury automatically at the end of its 30-year life, so the money and the tax liability arrive together and a Form 1099-INT follows. A paper certificate is not paid automatically. It reaches final maturity, stops earning, and continues to sit wherever it is, while the accrued interest has become reportable for that year. The holder can end up owing federal income tax on interest they have not physically received, and can end up owing it for a year they have long since filed. The fix is not complicated, which is why the date is worth checking rather than assuming: find the issue date and redeem the bond in the year it matures, or at least know that the year has arrived.

Two smaller mechanics worth carrying. An accrual-method taxpayer has no choice at all: Publication 550 says interest must be reported each year as it accrues, and reporting cannot be postponed until receipt or maturity. And Treasury's own regulations put a deadline on claiming a lost bond, one that differs by series because a different part of the regulations governs each. For definitive, meaning paper, Series EE and HH bonds, 31 CFR 353.29(c) provides that "no claim filed six years or more after the final maturity of a savings bond will be entertained unless the claimant supplies the serial number of the bond", and 31 CFR 315.29(c) says the same for the older definitive bonds it governs, Series E among them. Paper Series I bonds sit under 31 CFR part 360, and its rule is stricter rather than merely different: section 360.29(c) provides that "any claim filed 10 years or more after the maturity of a savings bond will be barred", with no serial-number exception at all. So recording serial numbers keeps an EE or HH claim alive past the six-year point, and for a Series I bond nothing does once the ten years have run.

How to find the date. Every paper certificate prints its issue date, and Publication 550 notes that the issue date assigned to a bond is the first day of the month in which it was purchased, which can be earlier than the day someone remembers buying it. Add the series' maturity period to that date. For an electronic bond the account shows the maturity date directly. TreasuryDirect's Savings Bond Calculator does the same job for a paper bond and also reports what it is currently worth.

The sequence is the same for every savings bond. It is issued on the first day of the month it was bought. It accrues interest for the period its series carries, 30 years for a Series EE or Series I bond. On the anniversary that ends that period it reaches final maturity and stops earning. If it is electronic, Treasury redeems it and pays the proceeds into the owner's account. If it is paper, nothing happens until it is presented. Either way, the accrued interest becomes reportable for that tax year under the IRS's Method 1, unless the owner had already been reporting it annually under Method 2.

A hypothetical showing the exposure, with invented amounts. Wesley holds a paper Series EE bond with an issue date of June 1994. Adding the 30-year maturity period, the bond reaches final maturity in June 2024 and stops earning. Suppose he paid $500 for it and its redemption value at that point is $2,000. The accrued interest is $2,000 minus $500, which is $1,500. Because he never elected to report the interest annually, he is on Method 1, and Method 1 ends the deferral at the earlier of redemption and maturity, so the $1,500 is reportable on his 2024 federal return whether or not the certificate ever left the drawer. Had the bond been electronic, Treasury would have redeemed it in June 2024, the $2,000 would have reached his account, and a Form 1099-INT would have arrived the following January reporting the same $1,500. The dollar figures are made up; the timing and the arithmetic are the point.

Pros

• The date is knowable in advance and never moves. Issue date plus the series' maturity period is the whole calculation.
• For an electronic bond, Treasury does the work: the bond is redeemed at final maturity and the tax reporting follows the money.
• Reaching final maturity does not put the money at risk. A matured bond is still payable in full; it has simply stopped growing.
• Treasury's Savings Bond Calculator answers both questions for a paper bond at once, the current value and the maturity date.

Cons

• A paper bond past final maturity earns nothing and is paid to nobody, so the holder loses return for every year it stays unpresented.
• The federal tax on the accrued interest comes due in the maturity year whether or not the bond was cashed, which can mean tax on money not received.
• Nothing prompts the holder of a paper bond. There is no notice and, since September 2025, no Treasury search tool to catch a forgotten one.
• Discovering the problem years later means amending a return rather than filing one, because the reportable year was the maturity year.
• Claiming a lost bond gets harder with time, and the deadline depends on the series. After six years past final maturity a paper EE or HH claim needs the serial number, which is precisely what a lost bond takes with it, and a paper Series I claim is barred outright ten years after maturity.
