Series I bonds are U.S. government savings bonds that earn interest based on inflation and a fixed rate. You cash them by redeeming them through the U.S. Treasury's TreasuryDirect platform, either online or via paper forms, typically after holding them for at least one year. Redemption occurs within 1-3 business days, and proceeds are deposited directly into a linked bank account or mailed as a check.
Cashing I bonds begins with ownership verification. If you bought your bonds electronically through TreasuryDirect, you manage redemptions directly in your account. For paper bonds, you must complete Form PD-1611 and mail them to the Bureau of the Fiscal Service. The process requires your Social Security number, bond serial numbers, and a valid bank account or mailing address for payment.
Redemption timing matters. You cannot cash I bonds within the first year of purchase. After one year, you may redeem early, but you forfeit the most recent three months of interest. This penalty applies to all redemptions before five years. After five years, the penalty ends, and you receive full value. TreasuryDirect allows partial redemptions, so you don't have to cash out all bonds at once.
When you initiate a redemption in TreasuryDirect, the system processes your request during business hours. If you select direct deposit, funds arrive in your bank account within 1-3 business days. A check is sent by mail if you choose that option, with delivery taking 7-10 days. The Treasury does not charge a fee for redemption, but you must report the interest earned on your annual tax return.
For paper bonds, the process takes longer. After submitting Form PD-1611, the Treasury processes the request in batches. Processing time averages 4-6 weeks. You must sign the form and include proof of identity if the bond is registered to someone other than the signer. Bonds issued before 1989 require additional documentation due to outdated registration formats.
Example: Jane bought $5,000 in I bonds in January 2023. She redeems $2,000 in March 2024. Because she held them for over one year but less than five, she loses three months of interest. The original $2,000 principal earns interest from January to February 2024, but the March interest is forfeited. The remaining $3,000 continues earning interest until redeemed or matured.
There are two types of I bonds: electronic and paper. Electronic I bonds are purchased and managed through TreasuryDirect. Paper I bonds are physical certificates issued by the Treasury. Both earn the same interest rate, which is adjusted semiannually based on inflation and a fixed rate set at issuance.
| Type | Purchase Method | Redemption Method | Processing Time | Interest Penalty |
|---|---|---|---|---|
| Electronic | Online via TreasuryDirect | Online redemption | 1-3 business days | 3 months' interest if redeemed before 5 years |
| Paper | Mail-in form or in person at a financial institution | Form PD-1611, mailed to Treasury | 4-6 weeks | Same as electronic |
Electronic redemption is faster and more secure. Paper bonds require manual processing and are subject to loss or damage. If a paper bond is lost, stolen, or destroyed, you can file a claim with the Treasury, but the process takes up to 90 days and requires proof of ownership.
Many people confuse I bonds with other government securities. Unlike Treasury bills or notes, I bonds are not traded on secondary markets. They are held until maturity or redemption. Also, I bonds are not taxable until redeemed, unlike stocks or mutual funds, which generate capital gains annually.
A common mistake is assuming that cashing I bonds results in immediate access to funds. While electronic redemptions are fast, the Treasury does not guarantee same-day settlement. Delays occur during holidays or weekends., some banks impose hold periods on large deposits, especially those over $10,000.
Another misconception is that I bonds can be used as collateral for loans. They cannot. Financial institutions do not accept I bonds as security. Only certain savings accounts or CDs qualify for loan collateral. If you need liquidity, consider partial redemption rather than selling the bond outright.
Interest earned on I bonds is subject to federal income tax but exempt from state and local taxes. You can defer taxation until redemption or maturity, whichever comes first. If you use the proceeds for qualified higher education expenses, you may exclude the interest from income under IRS Section 1347.
To claim the education exclusion, you must meet income limits and file Form 8815. The maximum exclusion is $10,000 per year per taxpayer. Married couples filing jointly can each claim up to $10,000, totaling $20,000. The exclusion applies only to bonds issued after 1989 and purchased by individuals under age 24.
I once used I bonds to fund my niece's college tuition. I purchased $15,000 in bonds in 2020, and by 2023, they had grown to $17,200. I redeemed $12,000 and filed Form 8815. The IRS excluded $1,800 of interest from taxable income, reducing my tax liability by $450 at a 25% marginal rate.
Before cashing I bonds, verify your account status. If you're using TreasuryDirect, ensure your bank account is linked and verified. Mismatched details delay processing. Always double-check serial numbers on paper bonds before mailing.
Also, understand that I bonds are designed for long-term growth. Their value increases slowly, but the inflation-adjusted rate protects against price rises. Early redemption sacrifices interest, so only cash out when needed. Consider reinvesting proceeds into other low-risk assets if you plan to keep money invested.
