When a retirement account passes to an adult child, a sibling, or a friend, the tax rules that once let heirs draw the money down slowly over a lifetime are largely gone. For most people who inherit a traditional IRA today, the entire balance has to come out within ten years, and every dollar pulled from that account counts as ordinary taxable income. Handled carelessly, that compressed window can push a middle-income heir into a higher bracket and quietly return a large slice of the inheritance to the government.
What the Ten-Year Rule Actually Requires
The change traces to the SECURE Act, which reshaped how inherited accounts are treated. Under the current framework spelled out by the IRS, if the original owner died after the end of 2019, most non-spouse beneficiaries must empty the inherited account by the close of the tenth year after the year of death. The rule applies whether the account is a traditional IRA, a Roth IRA, or an inherited 401(k)-style plan, and it holds regardless of the beneficiary’s own age.
The practical trap is the tax treatment. A traditional inherited IRA has never been taxed, so withdrawals are taxed as income to the heir in the year they are taken. An heir who lets the balance sit untouched for nine years and then withdraws it all at once can face a single enormous taxable event, layered on top of wages or other retirement income. The IRS guidance for IRA beneficiaries lays out the timeline, but it does not soften the arithmetic: ten years is the outer limit, not a suggestion to wait.

The Heirs Who Can Still Stretch Withdrawals
Not everyone is bound by the ten-year clock. The law carves out a category the IRS calls eligible designated beneficiaries, and they may still spread distributions across their own life expectancy. That group includes a surviving spouse, a minor child of the original owner, a beneficiary who is disabled or chronically ill, and any beneficiary who is not more than ten years younger than the person who died.
Those exceptions matter because they can dramatically lower the annual tax hit. A disabled heir or a sibling close in age, for example, may be able to take much smaller yearly withdrawals rather than clearing the account inside a decade. A minor child gets special treatment only until reaching the age of majority, at which point the ten-year rule generally kicks in for whatever remains. Everyone outside these narrow categories should assume the ten-year deadline applies.
The Penalty for Ignoring a Required Withdrawal
Inside the ten-year window, some beneficiaries also owe annual required minimum distributions, depending on whether the original owner had already reached the age when withdrawals were mandatory. Missing one of those required amounts carries its own cost. The IRS imposes an excise tax on the shortfall — the portion that should have been withdrawn but was not. That penalty is charged on top of the ordinary income tax the heir will still owe when the money finally comes out.
There is a measure of grace built in. As the IRS distribution FAQs explain, the penalty can be reduced when the mistake is corrected promptly, and the agency can waive it entirely for a reasonable error if the account holder takes the missed amount and files the proper form. Still, relying on forgiveness is a weak plan. An heir who does not know whether annual withdrawals are required should confirm the account owner’s date of death and age at death before assuming the ten-year deadline is the only thing to watch.
Why Spreading Withdrawals Beats a Final-Year Cliff
The smartest defense against the tax bill is usually to move money out steadily rather than waiting. Taking roughly even withdrawals across the ten years lets an heir fill up the lower tax brackets each year instead of stacking a decade of income into one return. A retiree who inherits an account and is temporarily in a low-income year — before claiming Social Security, or during a gap between jobs — may want to accelerate withdrawals into that window while the tax rate is low.
Roth inheritances change the calculation. Because a Roth IRA was funded with money already taxed, an inherited Roth generally comes out tax-free, so the ten-year rule becomes a question of timing rather than tax cost, and letting the balance grow untouched until year ten can make sense. For a traditional account, the opposite instinct usually wins. The heirs who lose the most are the ones who treat the ten-year rule as permission to do nothing, then discover in the final year that the entire inheritance is taxable at once. Anyone weighing an inherited account against other income should map out the withdrawals early, ideally with a tax professional who can model the bracket effects year by year.
