Do I Have to Pay Tax on Inherited Savings Bonds?

Yes, you generally owe federal income tax on inherited savings bonds, but only on the interest, not the original purchase price. The accrued interest that built up during the original owner’s life is classified as income in respect of a decedent, so it never gets the basis step-up that shelters most inherited property. Someone has to report that interest and pay tax on it. The useful news is that you, the executor, or the estate can choose which of you does the reporting, and that choice often controls how large the tax bill turns out to be.

Why the Interest Is Taxable at All

Most inherited property gets a favorable reset: its tax basis moves up to fair market value at the date of death, wiping out any built-in gain. Savings bond interest works differently. The IRS treats the accrued, untaxed interest as income in respect of a decedent (IRD), meaning the original owner earned it but never reported it on a return, and it must eventually be taxed to somebody.¹ Federal regulations list Series E and EE bond interest held by a cash-method taxpayer as a textbook example of IRD.²

A parent who bought $10,000 in EE bonds twenty-five years ago might leave behind bonds now worth $25,000. The principal is not taxed, but every dollar of that $15,000 in accrued interest is taxable income to someone. Death doesn’t exempt it.

Who Reports the Interest, and When

Three paths exist, and each puts the tax bill on a different taxpayer.

Report It on the Decedent’s Final Return

The executor can elect to include all interest earned through the date of death on the decedent’s final Form 1040. After that election, the beneficiary who later cashes the bond only owes tax on interest earned after the date of death.¹ This option shines when the decedent had low income in the year of death, dropping the interest into a lower bracket than the beneficiary would face.

Report It Through the Estate

If the bonds pass through the estate, the estate can report the accrued interest on its fiduciary income tax return (Form 1041). This works when the estate has deductions available to offset the interest, or when the beneficiary sits in a high bracket. Estates hit the top 37% federal rate at fairly modest income levels, though, so this route doesn’t always help.

Defer and Report When You Redeem

The most common choice: take ownership of the bonds and keep deferring. No income is reported at the time of inheritance. You eventually report all accrued interest when the bond is redeemed or reaches final maturity.³ This preserves tax-deferred compounding but concentrates a potentially large lump of income into a single tax year.

Which Option Costs the Least

Compare marginal tax rates. For 2026, federal brackets for single filers run from 10% on the first $12,400 of taxable income up to 37% on income above $640,600. For married couples filing jointly, the 37% rate begins above $768,700.⁴

Say a parent dies mid-year with only $30,000 of other income, putting them in the 12% bracket as a single filer. The beneficiary earns $200,000 annually and sits in the 32% bracket. On $15,000 of accrued bond interest, reporting on the decedent’s final return saves roughly $3,000 in federal tax compared to letting the beneficiary cash out later. The gap widens with larger bond portfolios.

Deferral makes sense when the beneficiary expects to be in a lower bracket in a future year (retirement, a career gap, a sabbatical) and can time the redemption. Holding the bond also lets interest keep compounding tax-free, which has real value if the bond is still years from maturity.

Avoiding Double Tax When You Finally Cash Out

When you redeem an inherited bond, the paying agent issues a 1099-INT showing all interest earned over the bond’s entire life, including any portion already reported on the decedent’s final return.³ If you don’t back out the previously reported amount, you pay tax on the same interest twice.

The fix is on Schedule B: report the full 1099-INT amount, then subtract the portion previously reported by the decedent on a separate line, with a notation like “interest previously reported by decedent.” Keep a copy of the decedent’s final return showing the exact bond interest figure. You’ll need it years later, when the redemption happens and memories have faded.

The IRD Deduction if Estate Tax Was Paid

If the estate was large enough to actually owe federal estate tax, the bond’s full redemption value was included in the taxable estate, and the same interest can get hit twice: once by estate tax, again by income tax when the beneficiary cashes out. Section 691(c) provides a deduction to prevent that overlap, calculated by comparing the estate tax actually paid with what it would have been if the IRD items had been excluded from the gross estate. Individuals claim the deduction on Schedule A; estates claim it on Form 1041.¹

For 2026, the federal estate tax exemption is $15,000,000 per person.⁵ Most estates fall well below that, so the Section 691(c) deduction is irrelevant to the typical inheritance. If you’re dealing with an estate above the threshold, get professional help; the calculation is intricate enough to justify the fee.

Watch for Bonds That Already Matured

Series EE and Series I bonds reach final maturity 30 years after their issue date, and at that point they stop earning interest entirely.⁶ A bond you’re holding for continued deferral does you no good once it has stopped earning. The tax bill is already locked in, and every extra year of holding just delays it while your money sits idle.

When an electronic bond matures in TreasuryDirect, the funds automatically shift into a non-interest-bearing Certificate of Indebtedness, and a 1099-INT is issued for all lifetime interest.³ Paper bonds past maturity just sit. Check the issue date on every inherited bond before deciding to hold. If it’s more than 30 years old, redeem it.

The Education Exclusion Won’t Help

Savings bond interest can be excluded from income if the proceeds pay for qualified higher education expenses, and beneficiaries sometimes assume that inherited bonds used for a child’s tuition qualify. They don’t. The exclusion requires that the bonds were issued in your name (or jointly with your spouse) and that you were at least 24 years old when they were issued. Bonds inherited from a parent or grandparent were originally issued in someone else’s name and fail the ownership test. Reissuing the bond in your name after death doesn’t cure the problem. The exclusion also phases out at higher incomes: for 2025, it starts phasing out at $99,500 for single filers and $149,250 for joint filers, and disappears entirely at $114,500 and $179,250.⁷ Inherited bonds are taxable regardless of what you spend the money on.

State Tax Treatment

Savings bond interest is exempt from state and local income tax, and that exemption survives inheritance.³ The bonds themselves, however, can be subject to separate state estate or inheritance taxes. Several states impose estate taxes with exemption thresholds well below the federal $15 million level, and a smaller group imposes inheritance taxes based on the beneficiary’s relationship to the decedent, with rates that range from 0% for close relatives up to 18% for unrelated beneficiaries. Rules vary enough by state that checking your own state’s requirements is worth the time.

Timing Redemptions to Keep the Tax Bill Down

If you chose to defer, the question turns to when to cash out. A single-year redemption of a large portfolio can push you into a higher bracket, especially if you already have significant income. A few moves help:

Stagger redemptions across tax years. Multiple inherited bonds cashed one or two per year spread the taxable interest instead of stacking it.
Target low-income years. Retirement, a sabbatical, or a gap between jobs opens a window at a lower bracket.
Check maturity dates first. Anything at or past 30 years should be redeemed regardless of bracket.
Line up other deductions. A year with unusually high medical expenses or charitable giving can partially offset the bond interest.

Series I bonds keep accruing interest at their inflation-adjusted rate while a beneficiary holds them, so there’s a genuine compounding benefit to keeping them if they’re years from maturity and the current rate is competitive. EE bonds issued after May 2005 earn a fixed rate, which makes the hold-versus-cash math more straightforward.

Whatever you decide, hang onto the decedent’s records: purchase date, denomination, series, and any interest already reported on the final return. You’ll need every one of those figures when the 1099-INT arrives.
