The best time to cash out I bonds is after they’ve been held at least one year, ideally past the five-year mark so you avoid the three-month interest penalty, and always on the first business day of a month that follows a low-earning stretch in the bond’s rate cycle. Get those three things aligned and you keep every dollar the bond earned for you. Get them wrong and you can hand back some of the strongest months of interest the bond ever paid.
The Two Rules That Set the Floor
Nothing about timing matters until you clear the first hurdle: an I bond cannot be redeemed at all during its first 12 months. There is no hardship access and no early-withdrawal option outside a federally declared disaster area.1eCFR. 31 CFR Part 359 – Offering of United States Savings Bonds, Series I – Section: 359.6 If there’s any real chance you’ll need the money inside a year, an I bond is the wrong place for it.
After 12 months you can redeem whenever you want, but cashing out before the bond turns five costs you the last three months of interest. The Treasury pays you as if you had redeemed three months earlier than you actually did. Your principal is protected, so the penalty can never dip below what you originally paid.2eCFR. 31 CFR Part 359 – Offering of United States Savings Bonds, Series I – Section: 359.7
Once the bond passes its fifth birthday, the penalty is gone for good. You keep everything.
Time the Penalty to Land on Weak Months
The three months you forfeit aren’t averaged across the bond’s life. They are specifically the three calendar months immediately before your redemption. That’s the lever you can pull.
I bond earnings combine a fixed rate that stays with the bond for its entire life and a variable inflation rate that resets every six months from the bond’s own issue date, not from the Treasury’s May 1 and November 1 announcement dates.3TreasuryDirect. I Bonds Interest Rates Because the inflation piece can swing hard from one six-month period to the next, one stretch of your bond’s life may pay meaningfully more than the next.
Say a bond earned a strong rate through April and then reset lower in May. Redeeming in May, June, or July would sacrifice three months of the high-rate stretch as the penalty. Waiting until August pushes the penalty forward onto the weaker months of May, June, and July, and the strong months already earned stay in your pocket. To use this, you need to know your specific bond’s reset dates, which run from its issue date rather than the Treasury’s announcement calendar.
Past the five-year mark, none of this matters and you can leave whenever you like.
Cash Out on the First Business Day of the Month
Interest on an I bond accrues monthly and is credited on the first day of each month; there is no partial-month interest.4TreasuryDirect. Questions and Answers about Series I Savings Bonds – Section: REDEMPTION AND REISSUE A bond cashed on March 2 pays the same as one cashed on March 28.
So redeem early in the month. You collect that month’s full credit and can move the money into an account where it starts earning again, instead of leaving it idle for three or four weeks with nothing to show for the wait.
How Long You Can Keep Holding
I bonds earn interest for 30 years from the issue date. After that they stop growing entirely. Electronic bonds in TreasuryDirect are automatically cashed at maturity and the proceeds land in a Certificate of Indebtedness inside your account, which pays nothing. Paper bonds sit there unless you submit them yourself.5TreasuryDirect. I Bonds
Maturity also forces a tax event. If you deferred reporting the interest (the default), every accumulated year of it becomes reportable income in the year the bond matures, whether you cash it out or not.6TreasuryDirect. Tax Information for EE and I Bonds A forgotten bond in a drawer can produce a very ugly tax bill decades later. Track the 30-year date.
Between year five and year thirty, there’s no penalty pressure to redeem. Hold as long as the bond’s composite rate compares favorably to what you could earn elsewhere.
Match the Redemption to the Right Tax Year
I bond interest is subject to federal income tax but exempt from state and local income taxes.7eCFR. 31 CFR Part 359 – Offering of United States Savings Bonds, Series I – Section: Appendix D Most bondholders defer reporting the interest until the year they cash out or the bond matures. That deferral is a timing tool: if you expect a lower bracket in a specific future year (retirement, a career gap, a sabbatical), redeeming in that year can meaningfully cut the tax bite.
You can instead elect to report interest annually as it accrues, but the election covers all savings bonds you own and any you later buy, and reversing it requires IRS permission. For most people, deferral wins.
The Education Savings Bond Exclusion
If you use the redemption proceeds to pay qualified higher education expenses in the same tax year, you may exclude the interest from federal income tax entirely. Qualified expenses are tuition and required fees at eligible institutions; room, board, and books do not count.8Office of the Law Revision Counsel. 26 USC 135 – Income from United States Savings Bonds Used to Pay Higher Education Tuition and Fees
Several conditions have to line up:
- The bond must have been issued to someone who was at least 24 years old at the time of purchase.
- Married couples must file jointly. Filing separately disqualifies you regardless of income.
- Total redemption proceeds (principal plus interest) cannot exceed the qualified expenses paid that year. If proceeds exceed expenses, the excludable interest shrinks proportionally.
- For tax year 2026, the exclusion phases out for single filers with modified adjusted gross income between $101,800 and $116,800, and for joint filers between $152,650 and $182,650. Above those ceilings, no exclusion is available.9Internal Revenue Service. Revenue Procedure 2025-32 – Section: 4.17
The exclusion is claimed on IRS Form 8815.10Internal Revenue Service. Form 8815 – Exclusion of Interest From Series EE and I U.S. Savings Bonds Issued After 1989 Timing traps hit hard here. Cashing out in December to cover a January tuition bill splits the proceeds and the expense across two tax years and can void the exclusion. Redeem in the same calendar year you pay the qualifying tuition.
Narrow Exceptions to the Timing Rules
Two situations open doors that are otherwise closed, and it’s worth knowing where they don’t apply.
If you live in an area covered by an official federal disaster declaration, the 12-month lock lifts. For electronic bonds, you call TreasuryDirect at 844-284-2676 or submit a certified FS Form 5512 with “DISASTER” written on the envelope and the top of the first page. For damaged or contaminated paper bonds, FS Form 1048 does the same job.11TreasuryDirect. Savings Bonds Affected by a Disaster Absent a disaster declaration, there is no hardship waiver.
If the bondholder dies and the bond names a surviving co-owner or beneficiary, ownership passes directly to that person without going through probate, and they can cash, reissue, or continue holding it.12TreasuryDirect. Death of a Savings Bond Owner The 12-month lock and the five-year penalty still apply to the bond itself; death doesn’t reset them.
Getting the Money Out
Electronic bonds redeem through TreasuryDirect. Log in, open ManageDirect, choose “Redeem securities,” pick the bond, and select the bank account for the deposit. Partial redemptions are allowed with a $25 minimum and at least $25 left in the bond, which lets you pull just what you need and leave the rest earning.13TreasuryDirect. How Do I…? – Section: Redeem Securities Funds typically arrive at your bank within a couple of business days.
Paper bonds have to be cashed at a financial institution. Banks are required to redeem for their established account holders with proper ID but are not obligated to serve non-customers, and the Secret Service advises them to decline for customers with accounts under 12 months old.14TreasuryDirect.

Call ahead; not every branch handles savings bonds, and some cap the amount per visit.
