The Ten-Year Countdown: What Inheriting a Retirement Account Now Costs Your Family in Taxes

For decades, inheriting an IRA came with a meaningful gift embedded in the tax code: the ability to stretch distributions across a beneficiary's lifetime. A 35-year-old who inherited a $500,000 IRA from a parent could take small annual distributions, allow the remainder to continue growing tax-deferred, and convert what might have been a single large tax event into decades of manageable income.

That strategy no longer exists for most beneficiaries. The Setting Every Community Up for Retirement Enhancement Act — the original SECURE Act, passed in late 2019 — eliminated the stretch IRA for the vast majority of non-spouse heirs. Its successor legislation, SECURE 2.0, enacted in December 2022, further refined and in some respects complicated the rules. What remains is a ten-year distribution window that demands attention, planning, and in many cases, a significant recalibration of how families think about inherited wealth.

What the Ten-Year Rule Actually Requires

Under current law, most non-spouse beneficiaries who inherit an IRA must fully distribute the account within ten years of the original owner's death. There is no requirement to take a specific amount each year — the beneficiary has flexibility in timing withdrawals within that window — but the account must be empty by December 31 of the tenth year following the year of death.

The implications depend heavily on the account type and on the circumstances of the original owner's death. If the IRA owner died before reaching their Required Beginning Date (RBD) — the age at which they were required to start taking RMDs, currently age 73 under SECURE 2.0 — beneficiaries have more flexibility. They can choose to take nothing for the first nine years and distribute the entire balance in year ten, or they can spread distributions however they choose across the decade.

However, if the original owner died after their RBD and had already begun taking Required Minimum Distributions, the picture is more complicated. IRS guidance issued in 2022 and finalized in 2024 clarified that in this scenario, beneficiaries must take annual RMDs during years one through nine, in addition to clearing the remaining balance by the end of year ten. Failure to take these annual distributions triggers a penalty — reduced from 50% to 25% under SECURE 2.0, and potentially as low as 10% if corrected promptly, but a penalty nonetheless.

Who Is Exempt — and Who Is Not

The ten-year rule applies to what the IRS designates as "non-eligible designated beneficiaries." This category covers the majority of adult children, grandchildren, siblings, and other individuals who inherit retirement accounts.

Certain beneficiaries retain the ability to stretch distributions over their own life expectancy. These "eligible designated beneficiaries" include:

• Surviving spouses, who may roll the inherited IRA into their own account and treat it as if it were always theirs
• Minor children of the original account owner — though only until they reach the age of majority, at which point the ten-year clock begins
• Disabled or chronically ill individuals, as defined under IRS criteria
• Beneficiaries who are not more than ten years younger than the original owner

For everyone else — which describes the experience of most American families navigating an inheritance — the ten-year rule applies in full.

The Tax Damage Hidden Inside the Clock

The ten-year window sounds generous in the abstract. In practice, it can compress what might have been a lifetime of tax-deferred growth into a decade of taxable income — and if that decade coincides with a beneficiary's peak earning years, the results can be genuinely damaging.

Consider an adult child who inherits a $400,000 traditional IRA at age 45 while earning $175,000 annually. If they distribute the account in equal installments of $40,000 per year, that additional income pushes them deeper into the 32% federal bracket — and potentially into the 35% bracket in higher-income years. Over ten years, the cumulative federal tax burden on those distributions alone could exceed $120,000, before accounting for state income taxes.

The scenario worsens if the beneficiary delays distributions and then faces a large required distribution in year ten. A $400,000 distribution in a single tax year would, in most circumstances, push a significant portion of that income into the highest federal brackets, generating a tax bill that might have been substantially reduced through more deliberate annual planning.

For inherited Roth IRAs, the calculus is different: distributions are generally tax-free, and the ten-year rule still applies, but the tax burden is absent. This is precisely why Roth conversions made by the original account owner during their lifetime can be one of the most impactful gifts they leave to heirs.

Strategies to Reduce the Tax Damage

For beneficiaries already holding inherited IRAs, several approaches can help minimize the tax impact of the ten-year distribution requirement.

Spreading distributions intentionally. Rather than allowing the account to grow and taking a large distribution in year ten, beneficiaries should model distributions across all ten years in a manner that keeps taxable income within manageable brackets. In years with lower earnings — a career transition, a sabbatical, early retirement — larger distributions may be absorbed at lower rates.

Coordinating with other income sources. Beneficiaries who also have deferred compensation, capital gains, or other variable income should model the interaction between those sources and inherited IRA distributions before making withdrawal decisions. The sequencing of income across a ten-year window can meaningfully affect the total tax paid.

Using charitable giving strategically. For beneficiaries who are charitably inclined, Qualified Charitable Distributions (QCDs) are not available for inherited IRAs in the same way they are for owned IRAs. However, large cash charitable contributions in high-distribution years can partially offset the tax impact of required withdrawals.

Considering a Roth conversion conversation with aging parents. Perhaps the most powerful intervention is one that happens before the inheritance occurs. Account owners who convert traditional IRA balances to Roth accounts during their lifetime — particularly in years when their own income is lower — are effectively prepaying tax on behalf of their heirs. The resulting Roth IRA still carries the ten-year rule for non-spouse beneficiaries, but the distributions arrive tax-free.

The Planning Imperative for Families With Significant Retirement Assets

The SECURE Act changes were not retroactive, but every traditional IRA established today will eventually be subject to these rules upon the owner's death. Families with substantial retirement assets — particularly those where one generation has accumulated significant balances in traditional IRAs or 401(k)s — should revisit their estate and beneficiary strategies with these rules explicitly in mind.

Beneficiary designations, trust structures, and Roth conversion timelines all interact with the ten-year rule in ways that can either amplify or substantially reduce the tax burden passed to the next generation. The families who act now, while there is time to plan, will be in a fundamentally different position than those who discover the consequences only after the inheritance has arrived.

The ten-year clock is already ticking for millions of American heirs. For those who have not yet started planning, the most expensive moment to begin is the one after it expires.
