When an IRA owner dies without a named beneficiary, the account almost always falls into the deceased owner’s estate, goes through probate, becomes reachable by the owner’s creditors, and must be emptied on an accelerated timeline that drives up the income tax the heirs eventually pay. That is what happens to an IRA without a beneficiary in the typical case, and every piece of it is avoidable with a single form filed with the custodian.
Who Actually Inherits First
Before probate enters the picture, the IRA custodian checks its own account agreement. Every custodian has a default beneficiary hierarchy that kicks in when the owner hasn’t filed a designation form. A typical default order names the surviving spouse first; if there is no spouse, the account goes to the owner’s estate. Some custodians insert children or other relatives into the chain, but many skip straight to the estate when no spouse exists. The specifics depend entirely on the language in the custodial agreement the owner signed when opening the account.
That default language decides whether the IRA ever touches the probate system at all. If the custodian’s agreement sends the account to a living spouse, that spouse can roll it into their own IRA and the story ends there. If the default points to the estate, everything below applies.
Probate Takes Over
Once the IRA is payable to the estate, the custodian will not release the funds until it receives proof that someone has legal authority over the estate. That proof comes as Letters Testamentary when there is a will, or Letters of Administration when there isn’t. Obtaining either requires filing a petition in probate court.
Probate timelines vary by jurisdiction, but most estates take nine to twelve months to close, and contested or complex estates can run two years or longer. The IRA sits frozen while the court supervises the process. The estate pays court filing fees, publication costs to notify creditors, appraisal fees, and attorney fees. In states with statutory fee schedules, attorney compensation is calculated as a percentage of the gross estate value, which can mean thousands of dollars on a mid-sized IRA before anyone inherits.
Probate also makes the IRA’s value public. The executor must file an inventory of estate assets, including the IRA balance, with the court, and those filings are open to anyone. A properly designated beneficiary avoids all of this because the IRA transfers privately, outside the court system entirely.1Internal Revenue Service. 5.5.2 Probate Proceedings
Creditors Reach the Account
Once the IRA enters the probate estate, it joins the pool of assets available to pay the deceased owner’s debts. Before heirs receive anything, the estate must satisfy outstanding obligations: medical bills, credit card balances, taxes, and funeral costs. If other liquid assets fall short, the executor may liquidate IRA funds to cover those debts. An IRA that passes directly to a named beneficiary generally stays out of reach of the decedent’s creditors because it never becomes estate property.1Internal Revenue Service. 5.5.2 Probate Proceedings
The Five-Year Distribution Deadline
The most damaging consequence of an IRA payable to an estate is the compressed payout window. Under Treasury regulations, an estate is not a “designated beneficiary” because only an individual qualifies for that status.2eCFR. 26 CFR 1.401(a)(9)-4 – Determination of the Designated Beneficiary That classification matters because the SECURE Act’s ten-year rule and life-expectancy options are available only to individual beneficiaries. An estate follows the older, pre-2020 rules.3Internal Revenue Service. Retirement Topics – Beneficiary
The exact deadline depends on whether the IRA owner had reached the Required Beginning Date for required minimum distributions, which is April 1 of the year after the owner turns 73.4Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs)
- If the owner died before the Required Beginning Date, the entire IRA must be emptied by December 31 of the fifth year after death. No annual withdrawals are required during that window, but the account must be fully depleted by the deadline.5Internal Revenue Service. Required Minimum Distributions for IRA Beneficiaries
- If the owner died on or after the Required Beginning Date, distributions continue over the deceased owner’s remaining single life expectancy, recalculated each year. This can extend the timeline beyond five years, but it is still shorter than what an individual designated beneficiary would receive.5Internal Revenue Service. Required Minimum Distributions for IRA Beneficiaries
Compare that to the options a named individual would have. A surviving spouse can roll the IRA into their own account and delay distributions until their own Required Beginning Date. Non-spouse individual beneficiaries get a ten-year window under the SECURE Act. The five-year deadline for estates is the most punishing timeline the tax code imposes on inherited IRAs.
Failing to withdraw enough in any given year triggers an excise tax equal to 25% of the shortfall between the required distribution and the amount actually taken.6Office of the Law Revision Counsel. 26 USC 4974 – Excise Tax on Certain Accumulations in Qualified Retirement Plans The penalty drops to 10% if the shortfall is corrected within two years by withdrawing the missed amount and filing a corrected return. Even with the reduced penalty, the underlying income tax on the distribution still applies.
The Tax Bill Gets Larger
Every dollar distributed from a traditional IRA is taxed as ordinary income, whether it goes to the estate or passes through to the heirs. The IRA’s balance is Income in Respect of a Decedent: money the owner earned but never paid tax on. That income keeps its character after death, so whoever receives it owes income tax at their own marginal rate.7Internal Revenue Service. Publication 559 (2025), Survivors, Executors, and Administrators
The compressed deadline makes the bill worse than it needs to be. Cramming an entire IRA balance into five tax years instead of spreading it over a decade or longer can push heirs into higher brackets. For 2026, the top federal rate is 37% on income above $640,600 for single filers and $768,700 for married couples filing jointly.8Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 A $500,000 IRA split across five years generates $100,000 of additional taxable income annually. Stacked on top of an heir’s regular salary, bracket creep becomes real.
If the estate retains the distribution rather than passing it through to heirs, the estate itself pays the income tax. Estate income tax brackets compress far more aggressively than individual brackets, which makes keeping large distributions inside the estate even more expensive.
Federal estate tax is a separate issue and will not affect most families. IRA assets are included in the gross estate regardless of whether a beneficiary is named, but the 2026 basic exclusion is $15 million per individual under the One, Big, Beautiful Bill signed into law on July 4, 2025.9Internal Revenue Service. What’s New – Estate and Gift Tax For the rare estate that owes both estate tax and income tax on the same IRA funds, heirs can deduct the portion of federal estate tax attributable to those distributions under the Income in Respect of a Decedent deduction.7Internal Revenue Service. Publication 559 (2025), Survivors, Executors, and Administrators
Roth IRAs Without a Beneficiary
Roth IRAs follow the same distribution timeline as traditional IRAs when no beneficiary is named. An estate inheriting a Roth IRA must still empty the account within five years if the owner died before the Required Beginning Date. The tax treatment is better: withdrawals of contributions from an inherited Roth are tax-free, and most withdrawals of earnings are also tax-free. The exception is a Roth account that was less than five years old at the time of death, in which case the earnings portion may be taxable.3Internal Revenue Service. Retirement Topics – Beneficiary
The tax-free treatment softens the blow, but the forced liquidation still destroys years of potential tax-free growth. A named individual beneficiary would get a full ten years to drain the Roth, and a surviving spouse who rolls it into their own Roth gets longer still. Losing five or more years of compounding inside a tax-free account is a real cost even when no income tax is owed.
How to Avoid All of This
Filing a beneficiary designation form with your IRA custodian is the single step that prevents everything above. Name both a primary and a contingent beneficiary. The contingent inherits if the primary dies before you, which keeps the IRA from defaulting to the estate through the custodian’s agreement.
Beneficiary designations override your will. If your will leaves the IRA to your spouse but the custodian’s form still names an ex-spouse, the ex-spouse inherits the account. This mismatch is the most common planning failure, and it happens constantly after divorce, remarriage, or the death of a previously named beneficiary. Pull up the form after any major life event and confirm it still matches what you want.
