The 10-Year Inherited IRA Rule That's Crushing Retirees' Legacies

The SECURE Act Eliminated the Stretch IRA

Before the SECURE Act took effect in 2020, a non-spouse beneficiary who inherited an IRA could spread distributions over their own remaining life expectancy. A 45-year-old inheriting from a parent with a 38-year IRS life expectancy factor could take distributions of roughly 2.6% of the balance annually - small enough to be barely noticeable on a typical tax return. The SECURE Act eliminated this for most non-spouse beneficiaries. The new rule: if you inherit an IRA from someone who died after December 31, 2019, and you are not the surviving spouse, a minor child, chronically ill, disabled, or no more than 10 years younger than the deceased, you must empty the inherited IRA within 10 years of the date of death. That sounds manageable on the surface. Ten years is a lot of time. But the IRS added a critical clarification in final regulations issued in 2024: if the original account owner had already reached their required beginning date (typically April 1 of the year after they turn 73), the beneficiary must also take annual RMDs during the 10-year period, based on the beneficiary's own life expectancy. This means many inheritors face the worst of both worlds: annual required distributions throughout the 10-year period, and a full liquidation requirement at the end. They cannot simply wait until year 10 and take it all then. For a $500,000 inherited IRA, the practical math: if annual RMDs run approximately $20,000-$25,000 throughout the decade, plus a substantial final distribution at year 10 of whatever remains, the tax burden is compressed and unavoidable.

The Tax Impact on Peak-Earning Heirs

The timing problem makes the SECURE Act change particularly harsh for the typical inheritor. Most adult children who inherit IRAs from their parents are in their 40s to 60s - often in their peak earning years, when their own salary income already places them in the 22-32% federal bracket. Here is what that looks like in practice. A 48-year-old professional earning $150,000 per year inherits a $600,000 IRA from a parent who passed at 78. Under the 10-year rule with annual RMDs required: The annual RMD for a 48-year-old beneficiary with a 36-year life expectancy factor would be approximately $16,700 in year one, growing over the 10-year period. But the final distribution in year 10 - whatever remains in the account - could easily be $300,000 to $400,000, depending on account growth. In the years of annual RMDs, the inheritor adds $16,700 to their $150,000 salary, pushing total taxable income to approximately $166,700 - firmly in the 24% bracket. Federal tax on that $16,700 is approximately $4,000. In the final year of forced distribution - suppose $350,000 remains - that $350,000 adds to the inheritor's $150,000 salary, creating $500,000 of taxable income. The marginal rate on the $350,000 inherited IRA distribution would be 32-35%, costing approximately $112,000-$122,500 in federal tax on that final distribution alone. From a $600,000 inheritance, the heir might net $430,000-$450,000 after 10 years of taxes on distributions - a real cost of $150,000-$170,000 to the IRS. Compare this to the pre-SECURE stretch approach where the annual distributions would have been small enough to potentially fall in the 12-22% range throughout.

Exceptions to the 10-Year Rule

Not everyone is subject to the 10-year rule. The SECURE Act created a category called 'Eligible Designated Beneficiaries' who can still use the lifetime stretch: Surviving spouses can treat the inherited IRA as their own and apply normal IRA rules, including delaying RMDs until their own RMD start age. This is the most favorable treatment available. Minor children of the account owner (not grandchildren) can use the stretch until they reach the age of majority (18-21 depending on state law), at which point the 10-year clock starts. Disabled or chronically ill individuals can still use their life expectancy for distributions. Beneficiaries who are no more than 10 years younger than the deceased can use their own life expectancy (this typically applies to siblings or friends of similar age). For everyone else - the vast majority of adult children and grandchildren inheriting from a parent or grandparent - the 10-year rule applies with full force. It is also worth noting that there is no estate tax step-up in basis for inherited IRA assets. Stock in a taxable brokerage account gets a step-up in basis at death, eliminating capital gains on all appreciation during the deceased's lifetime. An inherited IRA does not - every dollar is ordinary income when distributed, going all the way back to the original contributions.

What the Account Owner Can Do Now

The most powerful thing you can do to protect your heirs from the SECURE Act's 10-year rule is Roth conversion before you die. A Roth IRA is also subject to the 10-year rule for non-spouse beneficiaries - but Roth distributions are income tax-free. Your heirs face the same compressed timeline, but without the tax bill. For a $500,000 traditional IRA converted to Roth before death, your heirs inherit $500,000 of tax-free wealth. Yes, you pay income tax on the conversion - but you do it at your tax rate, and you may be in a lower bracket than your children will be when they inherit. The tax arbitrage is the core of the strategy: pay a lower rate now, so your heirs pay zero. Another approach is naming a charitable trust or donor-advised fund as partial beneficiary. Charitable beneficiaries can receive IRA distributions without income tax, allowing you to redirect some of your charitable giving through tax-efficient IRA assets while leaving Roth or life insurance assets to family heirs. Finally, understanding the exact 10-year rule requirements for your specific situation - whether annual RMDs within the 10 years are required based on whether you have already reached your required beginning date - is essential for your estate plan. The rules are detailed enough that the difference in your planning can save your heirs tens of thousands of dollars.

What Heirs Should Do After Inheriting

If you have already inherited an IRA under the 10-year rule, your primary decisions are about distribution timing - specifically, when within the 10 years to take distributions to minimize your tax burden. If annual RMDs are required, you must take them each year regardless. But for any amounts beyond the required minimum, you have flexibility. The key question: in which years is your income lowest? If you expect your income to drop significantly in years 6-10 - perhaps because you retire, lose a job, or have a sabbatical year - that is when to take larger discretionary distributions from the inherited IRA. Conversely, in your highest-earning years, take only the required minimum. Do not accelerate distributions into years when your marginal rate is 32-35%. Also consider whether contributing to other tax-advantaged accounts in the same year can offset some of the inherited IRA distribution. If you receive a large inherited IRA distribution in a year when you are also maximizing a 401(k) at $32,500 (if you are 50+), the 401(k) deduction partially offsets the inherited IRA income. The bottom line for both account owners and their heirs: the SECURE Act made inherited IRAs significantly more tax-expensive. The window to address this is now - either through pre-death Roth conversions by the account owner, or through strategic distribution timing by the heir.
