An IRA is part of an estate for tax purposes but usually not for probate. When the account owner dies, the IRA passes directly to whoever is named on the beneficiary designation form, skipping the probate court entirely. For federal estate tax, though, the IRS still counts the full value of the account in the deceased owner’s gross estate. And separately from either of those, the person who inherits a traditional IRA generally owes ordinary income tax on every dollar they withdraw.
Those three tracks — probate, estate tax, income tax — get tangled together in most explanations. Keeping them apart is the whole game.
Probate and Estate Tax Are Different Questions
Probate is the court process that validates a will and transfers assets the deceased owned in their sole name. An IRA doesn’t go through it because the beneficiary designation form is a contract with the custodian: the beneficiary shows up with a death certificate and receives the funds. No court, no executor, no waiting for a will.
The federal gross estate is a tax concept, not a probate list. The IRS includes assets the person owned or controlled at death regardless of how those assets transfer to heirs. An IRA counts. Life insurance often counts. Jointly held property counts. So an IRA can bypass probate completely and still sit inside the taxable estate.
One consequence people miss: the beneficiary form beats the will. If the will leaves everything to your daughter but the IRA form still lists an ex-spouse, the ex-spouse gets the IRA. Reviewing beneficiary designations after a divorce, remarriage, or the death of someone named on the form matters more than updating the will itself.
When an IRA Does Fall Into Probate
The IRA loses its non-probate status when there’s no valid beneficiary. That happens if the owner never filled out the form, if every primary and contingent beneficiary died before the owner, or if the form was improperly completed. In those situations, the custodian pays the IRA to the estate under the plan document’s default provisions.
Once inside the estate, the IRA is treated like any other probate asset. It’s exposed to court fees, administrative costs, and the deceased owner’s creditors. The distribution timeline also shrinks. If the owner died before their required beginning date for minimum distributions, the estate generally has to empty the account within five years. If the owner died on or after that date, distributions come out over the deceased’s remaining statistical life expectancy, which is usually shorter than the five-year window.1Internal Revenue Service.

Either way, the income tax bill hits faster than it would with a named individual beneficiary. Keeping a current beneficiary designation on file is the simplest way to prevent this.
Federal Estate Tax on an IRA
Every IRA is included in the owner’s gross estate at its fair market value on the date of death. Whether that triggers actual tax depends on the exemption.
The current basic exclusion amount is $15 million per person, adjusted annually for inflation.2Office of the Law Revision Counsel. 26 USC 2010 – Unified Credit Against Estate Tax Married couples can effectively double that through portability: the surviving spouse can use any unused portion of the deceased spouse’s exemption. Because of these thresholds, federal estate tax touches fewer than 1% of estates. For almost every IRA beneficiary, income tax is the tax that actually matters.
For estates large enough to owe federal estate tax, the IRA creates a real double-tax problem. It inflates the estate, then the beneficiary owes income tax on withdrawals. Federal law offers a partial fix: the beneficiary can claim an income tax deduction for the share of estate tax attributable to the IRA.3Office of the Law Revision Counsel. 26 USC 691 – Recipients of Income in Respect of Decedents The calculation is involved, and most beneficiaries in that position work with a tax professional.
Income Tax on What the Beneficiary Withdraws
Distributions from an inherited traditional IRA are taxed as ordinary income at the beneficiary’s own rate.3Office of the Law Revision Counsel. 26 USC 691 – Recipients of Income in Respect of Decedents The money went into the account pre-tax, so the IRS collects when it comes out.
Inherited IRAs also miss the step-up in basis that resets the cost basis on inherited houses and taxable brokerage accounts. The tax code specifically excludes property that represents income in respect of a decedent.4Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent The beneficiary inherits a zero basis on the deductible portion of the account and pays tax on every dollar distributed.
Inherited Roth IRAs are the exception. Because the original owner funded the Roth with after-tax dollars, qualified distributions come out tax-free to the beneficiary.5Internal Revenue Service. Retirement Topics – Beneficiary The beneficiary still has to follow the distribution timing rules, but the withdrawals themselves generally carry no income tax.
The 10-Year Rule and How Long You Have to Withdraw
Before 2020, most beneficiaries could stretch distributions over their own life expectancy. The SECURE Act of 2019 replaced that with a much tighter timeline for most non-spouse beneficiaries.5Internal Revenue Service. Retirement Topics – Beneficiary
The general rule is now the 10-year rule: the entire inherited IRA must be emptied by December 31 of the tenth year after the original owner’s death.5Internal Revenue Service. Retirement Topics – Beneficiary How you spread withdrawals across those years depends on when the owner died. If the owner had already reached their required beginning date, the beneficiary must take annual minimum distributions in years one through nine and clear the balance by the end of year ten. If the owner died before that date, the beneficiary has more flexibility about timing within the window.
The required beginning date for most IRA owners is April 1 of the year after they turn 73.6Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs)
Because the 10-year rule pushes all the money out in a short period, beneficiaries who inherit a large traditional IRA need to think about bracket management. Spreading withdrawals across the ten years is almost always better tax-wise than waiting until the final year and taking a huge lump.
Missing a required distribution triggers an excise tax of 25% of the shortfall. The rate dropped from 50% under the SECURE 2.0 Act, and if the beneficiary corrects the missed distribution within two years and files a return reflecting the correction, the penalty drops to 10%.7Office of the Law Revision Counsel. 26 USC 4974 – Excise Tax on Certain Accumulations in Qualified Retirement Plans The IRS has historically been willing to waive the penalty for genuine mistakes when the beneficiary corrects the error promptly.8Internal Revenue Service.

Who Is Exempt From the 10-Year Rule
A narrow group of beneficiaries, called eligible designated beneficiaries, can still stretch distributions over their own life expectancy:5Internal Revenue Service. Retirement Topics – Beneficiary
- A surviving spouse, who has the most flexibility of any beneficiary.
- A minor child of the deceased owner, who uses the life expectancy method until age 21 and then switches to the 10-year rule, emptying the account by age 31.
- A disabled individual, as defined by the IRS.
- A chronically ill individual, with medical certification.
- An individual not more than ten years younger than the deceased owner, which often covers siblings or partners close in age.
Everyone else, including adult children, grandchildren, friends, and most trusts, falls under the 10-year rule.
Options for a Surviving Spouse
A surviving spouse has three options no other beneficiary gets. First, they can roll the inherited IRA into their own IRA. This spousal rollover treats the account as if the surviving spouse had always owned it, so required minimum distributions don’t begin until that spouse turns 73.6Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs)
Second, the spouse can keep the account as an inherited IRA and take life expectancy distributions. Third, the spouse can use the 10-year method.
The rollover is usually the best choice for a spouse who doesn’t need the money right away, because it maximizes tax-deferred growth. But a spouse under age 59½ who needs access to the funds is often better off keeping it as an inherited IRA, because inherited IRAs avoid the 10% early withdrawal penalty that applies to a spouse’s own IRA.
Naming a Trust as the Beneficiary
Some owners name a trust as IRA beneficiary to control how heirs receive the money, usually because a beneficiary is a minor, has special needs, or isn’t trusted to manage a large sum. For the trust to work with an IRA, it must qualify as a “see-through” trust, meaning it is valid under state law, becomes irrevocable at the owner’s death, has identifiable beneficiaries, and is documented to the custodian by October 31 of the year after death.
Trusts come in two main varieties for this purpose. A conduit trust passes IRA distributions straight through to the beneficiary. An accumulation trust lets the trustee hold distributions inside the trust. Both generally follow the 10-year rule for non-spouse beneficiaries.
The catch with accumulation trusts is the tax math. Income retained inside a trust hits the top federal income tax bracket at just over $15,000 of taxable income, while an individual doesn’t reach that bracket until income exceeds roughly $600,000. IRA distributions held inside the trust get taxed at those compressed rates, and that cost is often the piece of an estate plan that goes wrong.
Inherited IRAs Aren’t Protected From Creditors
An IRA you build yourself receives strong protection from creditors in bankruptcy. An inherited IRA does not. In 2014, the U.S. Supreme Court ruled unanimously in Clark v. Rameker that inherited IRAs are not “retirement funds” under federal bankruptcy law and can be reached by a beneficiary’s creditors.9Justia Law. Clark v. Rameker, 573 US 122 (2014)
So if you leave a large IRA to an adult child who later faces a lawsuit or bankruptcy, those funds may be exposed. It’s one of the stronger arguments for naming a properly structured trust rather than an individual, particularly for large accounts. Some states have added their own protections for inherited IRAs, so the actual exposure depends on where the beneficiary lives. When an IRA drops into the estate because no valid beneficiary exists, those funds also lose their protected status and become available to the deceased owner’s creditors during probate.
State Estate and Inheritance Taxes
Federal estate tax is only half the picture. Twelve states and the District of Columbia impose their own estate taxes, and six states levy inheritance taxes, with one state imposing both.10Tax Foundation. Estate and Inheritance Taxes by State, 2025 State exemption thresholds are often much lower than the federal one. Some start as low as $1 million, which means the IRA’s inclusion in the taxable estate is far more likely to produce actual tax at the state level than at the federal level.
Inheritance taxes work differently from estate taxes. Instead of taxing the estate as a whole, they apply to each beneficiary individually, often at rates that depend on the relationship to the deceased. A spouse or child may pay nothing while a distant relative or unrelated person pays a significant percentage. If you or the deceased lived in a state with either tax, the combined federal and state treatment is worth reviewing with a professional before you take distributions.
