A Series EE bond is a U.S. Treasury savings bond that is non‑marketable (cannot be bought or sold on an open market), interest‑bearing, and backed by the full faith and credit of the U.S. government. EE bonds are sometimes called “Patriot Bonds” for paper certificates issued after Sept. 11, 2001. They are designed as ultra‑safe, low‑risk savings vehicles and carry a guarantee that the bond will be worth at least twice its original purchase amount at its 20‑year anniversary (the “doubling” guarantee). Some EE bonds continue to earn interest beyond 20 years, up to 30 years from issue.
Key takeaways
– Series EE bonds are non‑marketable U.S. government savings bonds intended for conservative investors.
– EE bonds issued after May 2005 receive a fixed coupon rate set each May 1 and November 1; values increase monthly but interest is posted semiannually.
– EE bonds are guaranteed to at least double in value by 20 years; they may earn interest for up to 30 years total.
– Interest is exempt from state and local taxes but subject to federal income tax, which is typically reported in the year of redemption or maturity.
– Minimum purchase and annual limits apply: $25 minimum; up to $10,000 per person per calendar year for electronic EE bonds (purchase rules differ for legacy paper bonds).
– Bonds must be held at least 12 months before redemption; redeeming within 5 years incurs a penalty equal to the last 3 months of interest.
How a Series EE bond works
– Purchase and form: EE bonds are sold electronically (via TreasuryDirect) at face value. Historically, paper EE (Patriot) bonds were issued at a 50% discount to face value; paper issues are no longer sold by financial institutions but can still be cashed or converted to electronic form.
– Rate setting: For EE bonds issued after May 2005, the Treasury announces a fixed rate semiannually (May 1 and November 1). That fixed rate applies to bonds issued during the subsequent six months. The rate is based on a percentage of long‑term Treasury rates.
– Interest accrual and crediting: Bonds increase in value monthly (interest accrues monthly). Interest is credited/compounded semiannually.
– Guarantee: The Treasury guarantees the bond’s value will at least double from its original purchase value by its 20th anniversary. If interest credited over 20 years hasn’t produced that doubling, the Treasury makes a one‑time adjustment at the 20‑year mark to bring the bond’s value to double the original purchase price.
– Maturity: EE bonds have an interest‑earning life that may extend up to 30 years from issuance; after that they stop earning interest.
Special considerations
– Taxation: Interest on EE bonds is exempt from state and local income taxes. Federal tax is due on the interest and is usually reported in the year you redeem the bond or when it matures (you may elect to report interest annually, but most taxpayers defer reporting until redemption/maturity).
– Liquidity and penalties: You must hold an EE bond at least 12 months. Redeeming within the first five years triggers a penalty of the last three months’ interest. After five years there’s no early‑redemption penalty (but the 12‑month minimum still applies).
– Purchase limits and eligible purchasers: Electronic EE bonds have a $25 minimum and a $10,000 per‑person, per‑calendar‑year purchase limit (electronic). Eligible buyers include U.S. citizens, U.S. residents (for tax purposes) and minors, and U.S. government employees (regardless of citizenship). Rules differ for legacy paper bonds.
– Paper vs electronic: Paper Patriot Bonds (post‑9/11 paper EE) were identical in economic terms to earlier EE bonds except for the “Patriot Bond” label; financial institutions no longer issue paper EE bonds. Paper bonds issued in the past at a discount remain redeemable; holders can also convert paper bonds to electronic form via TreasuryDirect.
Practical steps — buy, hold, convert, and redeem EE bonds
1) Decide whether an EE bond fits your goals
• Use Series EE bonds for capital preservation, predictable government backing, and federal tax advantages on state/local taxes.
• Consider other options (Series I bonds, TIPS, CDs, municipal bonds) if you need inflation protection or higher expected returns.
2) Open a TreasuryDirect account (for electronic EE bonds)
• Go to treasurydirect.gov and set up an individual account (you’ll need your Social Security number, a U.S. address, and a checking or savings account for fund transfers).
• Note: TreasuryDirect is the Treasury’s official platform for buying and holding electronic savings bonds.
3) Purchase an EE bond
• Log in to TreasuryDirect, choose Series EE, enter the purchase amount (minimum $25, then in $25 increments for some offerings), and complete the purchase using your linked bank account.
• Remember the $10,000 electronic annual per‑person limit (confirm current limits on TreasuryDirect, since rules can change).
4) Convert paper EE (Patriot) bonds to electronic (if desired)
• If you hold legacy paper EE bonds, you can convert them to electronic form via TreasuryDirect’s paper conversion process (visit TreasuryDirect for the exact submission procedure and required documentation). Paper bonds can also be cashed at a financial institution if immediate liquidity is desired.
5) Track interest and taxation
• Monitor bond value and accrued interest in your TreasuryDirect account (electronic) or via statements/receipts for paper bonds.
• Plan for federal tax on interest: you will typically report interest income in the year you redeem or when the bond matures. Keep records of purchase dates and amounts for accurate tax reporting.
6) Redeem when needed (and avoid unnecessary penalties)
• You cannot redeem within the first 12 months. If you redeem within the first five years, you forfeit the last three months of interest. After five years there is no federal penalty, but taxes still apply on accrued interest.
• For electronic EE bonds: redeem through TreasuryDirect and receive the proceeds via direct deposit to your linked bank account.
• For paper EE bonds: cash them at a financial institution (if accepted) or submit them for processing as instructed by the Treasury.
Simple example of the 20‑year guarantee
– If you buy an electronic EE bond for $100, the bond must be worth at least $200 at the 20‑year mark. That guarantee means your effective minimum average annual yield over 20 years is roughly 3.53% compounded annually (because 2^(1/20) − 1 ≈ 3.53%). The Treasury either credits sufficient interest over the 20 years or makes a one‑time addition at year 20 to meet the double‑value guarantee.
Important
– Rules, purchase limits, and procedures can change. Always confirm current details (rates, limits, conversion procedures, and tax treatment) on official Treasury resources (TreasuryDirect) or consult a tax advisor for how EE bond interest fits your tax situation.
