Series EE bonds mature at 30 years from the issue date

A Series EE savings bond stops earning interest exactly 30 years after you buy it. That date is printed on your bond—if you bought one on March 15, 2024, it matures on March 15, 2054. After that date, the bond no longer grows in value, even if you keep holding it.

The maturity date matters because it marks the end of the earning period. The U.S. Treasury guarantees that a Series EE bond will at least double in value over those 30 years, but only if you hold it for the full term. Once maturity arrives, that may provide stops applying.

You can cash in a Series EE bond anytime after you own it for one year. If you cash it in before 30 years have passed, you will owe a penalty: the loss of the last three months of interest. This penalty applies whether you cash it in at year 2 or year 29. The penalty is the same—three months' worth of earnings disappear.

Key Takeaways

  • Series EE bonds stop earning interest at exactly 30 years from the purchase date, which is printed on the bond itself.
  • The Treasury guarantees a Series EE bond will at least double in value over the full 30-year period, but this may provide ends at maturity.
  • Cashing in a bond before maturity costs you three months of interest, no matter whether you cash it in at year 2 or year 29.
  • After maturity, you can still hold the bond, but it will not earn any additional interest and should be cashed in or redeemed.
  • You cannot extend a Series EE bond past 30 years—once it matures, the earning period is finished.

What happens to your bond value at the 30-year mark

On the maturity date, your bond stops growing. If the bond has earned enough interest to double in value, it will have reached its full may provide amount. If interest rates were low during your holding period and the bond has not yet doubled, the Treasury will add a one-time payment to bring it up to exactly double the purchase price—this is the doubling may provide in action.

After maturity, the bond's value is locked. It will not increase by even one cent, no matter how long you hold it. The interest rate that was being applied to your bond—whether it was 1.5%, 2%, or something else—stops working on the maturity date.

Why you should cash in a mature bond

Once a Series EE bond matures, there is no reason to keep it. It is earning zero interest. The money is sitting idle when you could move it to a savings account, money market account, or another investment that continues to earn.

Mature bonds can be cashed in at most banks or through the Treasury's TreasuryDirect website. The process is straightforward: you provide proof of ownership and your Social Security number, and the Treasury sends you a check or deposits the money directly to your bank account. There is no penalty for cashing in a mature bond—the three-month interest penalty only applies if you cash in before the 30-year mark.

If you have lost track of a bond or cannot locate the physical certificate, you can still redeem it through TreasuryDirect by setting up an account and registering the bond. The Treasury keeps records of all registered bonds, so you do not need the paper certificate to claim what you own.

The difference between maturity and the doubling may provide

These two concepts are related but separate. The doubling may provide means the Treasury promises your bond will be worth at least twice what you paid for it. The maturity date is when the bond stops earning interest and the may provide period ends.

In most cases, a Series EE bond reaches double value before the 30-year maturity date arrives. Current interest rates determine how fast this happens. When rates are higher, bonds double faster. When rates are lower, it takes longer. If a bond has not doubled by year 30, the Treasury adds a lump-sum adjustment on the maturity date to make up the difference.

Once maturity arrives, the doubling may provide no longer applies. If you somehow still held the bond past year 30 (which you should not), the Treasury would not add any more money to it, and it would not earn interest.

How to find your bond's maturity date

The maturity date is printed directly on the bond certificate. Look for the issue date—the month and year you purchased it—and add 30 years. That is your maturity date.

If you own bonds through TreasuryDirect (the online system where you buy bonds electronically), log into your account and view your holdings. The maturity date is listed for each bond. TreasuryDirect also sends you email reminders as bonds approach maturity, though these reminders typically arrive a few months before the date.

For paper bonds, you can also contact the Treasury directly or visit the TreasuryDirect website to look up a bond by its serial number if you have misplaced the certificate.

What to do if you have already passed the maturity date

If you own a Series EE bond that matured years ago, it is still worth the value it reached at maturity. The bond has not lost value—it simply stopped growing. You can cash it in at any time with no penalty, because the three-month interest penalty only applies to bonds cashed in before maturity.

There is no deadline for cashing in a mature bond. You can hold it indefinitely without losing money, but you are also not earning anything. The practical choice is to cash it in and move the money somewhere it can continue to work for you.

If you have multiple bonds that matured at different times, you can cash them in one at a time or all at once—the choice is yours. Some people cash in mature bonds gradually to spread out the tax impact, since the interest earned on savings bonds is subject to federal income tax in the year you redeem them.

Tax considerations when a bond matures

The interest you earned on a Series EE bond is subject to federal income tax. You do not owe tax until you cash in the bond, so if you hold a bond for 30 years and then redeem it, you will owe tax on all 30 years of interest in that single tax year.

Some people space out redemptions of mature bonds across multiple years to keep their taxable income lower in any single year. This is a legitimate strategy, but it means keeping money in a non-earning bond while you wait. You should discuss the tax timing with a tax professional if you have a large number of mature bonds.

You can also report the interest on a Series EE bond each year as you earn it, rather than waiting until redemption. This requires filing Form 8815 with your tax return. If you choose this route, you will owe tax gradually instead of all at once, but you must be consistent—you cannot switch methods partway through holding the bond.

Frequently Asked Questions

Can I keep a Series EE bond after it matures?

Yes, you can hold it indefinitely, but it will not earn any interest. The bond's value is locked at maturity. There is no benefit to keeping it, and you should cash it in to move the money to an account or investment that continues to earn.

What if I cash in my bond one day before maturity?

You will lose three months of interest. The penalty is the same whether you cash in at year 2 or year 29. If your bond is about to mature, wait the extra day and cash it in after maturity to avoid this penalty.

Does the maturity date change if I do not cash in my bond?

No. The maturity date is fixed at 30 years from the issue date, regardless of whether you cash in the bond or hold it. Holding the bond past maturity does not extend the earning period.

How do I know if my old bond has matured?

Add 30 years to the issue date printed on the bond. If that date has passed, the bond has matured. You can also check TreasuryDirect or contact the Treasury to confirm the maturity date and current value.

Can I redeem a Series EE bond after maturity without the original certificate?

Yes. The Treasury keeps records of all registered bonds. You can redeem a mature bond through TreasuryDirect using your Social Security number and proof of ownership, even if you no longer have the paper certificate.
