The 10-Year Countdown: What Inherited IRA Beneficiaries Must Do Right Now to Avoid a 25% IRS Penalty

When someone inherits an individual retirement account, the emotional weight of the moment tends to overshadow the administrative urgency. That is understandable. It is also financially dangerous.

The rules governing inherited IRAs changed dramatically with the original SECURE Act in 2019 and were further refined by SECURE 2.0 in late 2022. Together, these legislative changes eliminated a distribution strategy that millions of Americans had relied upon for decades and replaced it with a compressed timeline that carries significant penalties for noncompliance. If you inherited a retirement account from someone who died after December 31, 2019, there is a strong possibility that a mandatory 10-year distribution window is already running—and that you may not have been told.

The Stretch IRA Is Gone

Prior to 2020, most non-spouse beneficiaries could elect what practitioners called the "stretch IRA" strategy. This approach allowed beneficiaries to take required minimum distributions based on their own life expectancy, potentially spreading withdrawals—and the associated tax burden—over several decades. A 35-year-old inheriting a $500,000 IRA from a parent could, under the old rules, take modest annual distributions for 40 or more years, allowing the bulk of the account to continue growing tax-deferred.

The SECURE Act eliminated this option for most beneficiaries. In its place, Congress imposed a single rule for the majority of inheritors: the entire account must be distributed within 10 years of the original owner's death. There are no required annual distributions during those 10 years—but by the end of year 10, the account balance must reach zero.

The tax implications of this compression are substantial. A beneficiary who inherits a $400,000 traditional IRA and withdraws the entire balance in year 10 could face a significant income spike in that year, potentially pushing them into a higher bracket and triggering phase-outs or surcharges they would not otherwise encounter.

Not All Beneficiaries Face the Same Rules

The 10-year rule applies broadly, but it does not apply universally. The legislation created a category called Eligible Designated Beneficiaries (EDBs), who retain access to more favorable distribution options.

EDBs include:

• Surviving spouses, who can treat the inherited IRA as their own, roll it over into their own IRA, or take distributions over their own life expectancy.
• Minor children of the original account owner, who may use the stretch method—but only until they reach the age of majority, at which point the 10-year clock begins.
• Disabled individuals, as defined under IRS guidelines.
• Chronically ill individuals, under specific criteria.
• Beneficiaries who are not more than 10 years younger than the deceased, such as a sibling or a close-in-age friend named as beneficiary.

If you do not fall into one of these categories, you are a Non-Eligible Designated Beneficiary (NEDB) subject to the 10-year rule. If you are not a designated beneficiary at all—for instance, if the estate is named as beneficiary—a five-year rule may apply instead, depending on whether the original owner had already begun required minimum distributions.

The Annual Distribution Question: Still Unresolved, Still Consequential

One of the most frustrating aspects of the post-SECURE Act environment is that a critical interpretive question remained in dispute for years. The IRS proposed regulations in 2022 suggested that NEDBs who inherit from an owner who had already started required minimum distributions must take annual withdrawals during the 10-year window—not simply wait until year 10. This position was contested by tax professionals and confusing to beneficiaries.

The IRS waived penalties for missed annual distributions in 2021, 2022, 2023, and 2024 while it finalized the rules. Final regulations were published in 2024, and the annual distribution requirement for applicable NEDBs is now in effect beginning in 2025. Beneficiaries who assumed the 10-year rule meant they had a decade of flexibility with no annual obligations may now find themselves facing a compliance gap.

The practical implication: if you inherited a traditional IRA from someone who was already taking required minimum distributions before their death, and you are not an EDB, you likely must take annual distributions based on your own life expectancy from the IRS Single Life Expectancy Table—and the full balance must still be gone by year 10.

Calculating What You Owe and When

For beneficiaries subject to annual distribution requirements, the calculation begins with the prior year-end account balance divided by the appropriate life expectancy factor from IRS Publication 590-B. The life expectancy factor is reduced by one each subsequent year.

For example, a 45-year-old beneficiary inheriting in 2023 would reference the IRS table for a remaining life expectancy of approximately 38.8 years. The required distribution for the first applicable year would be the December 31 account balance divided by 38.8. The following year, the divisor drops to 37.8, and so on—while the 10-year endpoint remains fixed.

The penalty for failing to take a required distribution was reduced by SECURE 2.0 from 50 percent to 25 percent of the amount not withdrawn—still a severe consequence. If the error is corrected within two years, the penalty drops further to 10 percent. But these corrections require proactive engagement with the IRS and, in most cases, professional guidance.

Strategic Considerations for Managing the Tax Burden

The 10-year window, while constraining, does offer planning opportunities. Beneficiaries are not required to take equal annual distributions—they can front-load or back-load withdrawals based on their anticipated income trajectory.

A beneficiary who expects significant income growth over the next decade may be better served by taking larger distributions earlier, when their marginal rate is lower. Conversely, someone approaching retirement who expects income to decline in years six through ten might defer heavier withdrawals to that period.

For Roth IRA beneficiaries, the calculus differs. Inherited Roth IRAs are also subject to the 10-year rule for NEDBs, but qualified distributions from Roth accounts remain tax-free. The strategic imperative there is to allow the account to grow for as long as possible within the window, then withdraw the full balance in year 10 without income tax consequences—provided the five-year holding rule has been met.

What to Do If You Are Already Behind

If you inherited a retirement account after 2019 and have not yet consulted a tax professional about your distribution obligations, the time to act is now. The IRS penalty waiver periods have ended. The rules are final. The clock is running.

Start by identifying which beneficiary category applies to you, confirming whether the original owner was already taking required minimum distributions, and determining the year of death—which establishes when your 10-year window began. From there, a qualified tax advisor can model distribution scenarios and help you minimize the income tax impact of what is, in most cases, an unavoidable withdrawal obligation.

An inherited IRA is a gift. Treating it as anything less than a time-sensitive tax planning matter is the one decision that can undo much of its value.
