The Inherited IRA 10-Year Rule (and the 2024 Final Regs)

If you inherited an IRA from someone who died after December 31, 2019, you are not playing by the old rules. The stretch IRA, which let most beneficiaries take small distributions over their own life expectancy, is largely gone. What replaced it is more complicated than most people realize, and the IRS spent four years clarifying exactly how it works.

What the 10-Year Rule Actually Requires

The SECURE Act (effective January 1, 2020) eliminated the lifetime stretch for most non-spouse beneficiaries. In its place came a single requirement: the inherited IRA must be fully distributed by December 31 of the tenth year following the year of the original owner's death.

That sounds simple. The complication is whether annual distributions are also required inside that ten-year window, and the answer depends on how old the original account owner was when they died.

If the original owner died before their Required Beginning Date (RBD), which for most people is April 1 of the year after they turn 73, the beneficiary has complete flexibility. They can take nothing for nine years and drain the entire account in year ten. No annual minimums apply.

If the original owner had already passed their RBD and was actively taking RMDs, the picture changed with the 2024 final regulations. Under Treasury Regulation 1.401(a)(9)-5, finalized in July 2024, non-eligible designated beneficiaries in this situation must take annual RMDs in years one through nine, calculated on their own life expectancy, and then distribute whatever remains by the end of year ten. Both requirements apply simultaneously.

Eligible designated beneficiaries (surviving spouses, minor children of the deceased, disabled or chronically ill individuals, and beneficiaries not more than ten years younger than the owner) still have access to life-expectancy stretching and are not subject to the ten-year rule in the same way.

The Rules, the Penalty Relief, and the Watchouts

The IRS created an awkward situation between 2020 and 2024. The SECURE Act statute was unclear about whether annual RMDs were required when the original owner had passed RBD. The IRS proposed the annual-RMD requirement in 2022 regulations, then issued a series of penalty waivers covering 2021, 2022, 2023, and 2024 for beneficiaries who skipped those distributions while the rules were unsettled. Those waivers are now expired. The 2024 final regulations are the operative rules going forward, and beneficiaries should not assume ongoing relief will be granted.

A few other watchouts worth knowing:

• The ten-year clock runs from the year of death, not the year you open the inherited IRA. If you inherited in 2021, your deadline is December 31, 2031, regardless of when you established the account.
• Successor beneficiaries (someone who inherits an already-inherited IRA) face their own ten-year window, generally starting from the original beneficiary's death, not the original owner's death.
• Roth IRAs inherited from someone who died after their RBD are also subject to the ten-year rule for non-eligible designated beneficiaries, though the annual RMD requirement inside the ten-year window generally does not apply to inherited Roths because Roth owners have no RBD.

If you miss the ten-year deadline, the penalty is 25% of the amount that should have been distributed (reduced to 10% if corrected within the correction window under SECURE 2.0 rules).

A Worked Example: When Front-Loading Makes Sense

I had a client (this is illustrative, not a specific case) in her mid-40s who inherited a $400,000 traditional IRA from her father, who had died at 76 and was already taking RMDs. Under the 2024 final regs, she faced required annual distributions in years one through nine and a final distribution in year ten.

Her annual RMD in year one was roughly $19,000 based on her single life expectancy from the IRS uniform tables. That covered the floor. But her taxable income from her job left room before hitting the 24% bracket. Rather than taking only the minimum, we modeled taking $55,000 per year for the first several years, filling the bracket, and leaving a smaller residual balance to clear in year ten.

The logic is straightforward. Every dollar left in a traditional inherited IRA grows tax-deferred but will eventually be taxed as ordinary income. If her income rises substantially in her 50s, those later distributions land in a higher bracket. Pulling more forward while rates are relatively favorable reduces the total tax cost over the distribution window.

This kind of bracket-filling analysis lives squarely in what we call the Harvest stage of a retirement plan, where the sequence and timing of distributions determines after-tax outcomes. You can read more about how RMDs and inherited accounts fit into that framework on the parent page, RMDs and QCDs: The Required-Distribution Rules That Shape Retirement Income After 73.

How This Connects to the Soil Layer of Your Plan

Inherited IRA strategy is ultimately a tax-architecture problem. The question is not just "when do I have to take money out" but "in what order, at what amounts, and in which years does taking money out cost the least." That is the Soil layer of a well-built plan: the decisions you make about account structure and tax exposure that shape every dollar that flows through for the next decade.

For beneficiaries who also hold their own retirement accounts, the interaction between inherited IRA distributions, their own future RMDs, and any Roth conversion strategy compounds the complexity. These plans should not be built in isolation.

Frequently Asked Questions

Does the 10-year rule apply to a spouse who inherits an IRA?

No. A surviving spouse is an eligible designated beneficiary and can roll the inherited IRA into their own IRA, treating it as if it were always theirs. They are not subject to the ten-year rule.

What if I inherited the IRA before 2020?

If the original owner died before January 1, 2020, the old stretch rules apply to your account. You continue taking distributions based on your original life-expectancy calculation. The SECURE Act changes do not apply retroactively to pre-2020 inheritances.

Can I convert an inherited IRA to a Roth?

No. Non-spouse beneficiaries cannot convert an inherited traditional IRA to a Roth. Only a surviving spouse who rolls the inherited IRA into their own account can then do a Roth conversion.

What happens if I miss an annual RMD inside the 10-year window?

The penalty is 25% of the shortfall (the amount you should have taken but did not). SECURE 2.0 reduced the old 50% penalty. The penalty drops to 10% if you correct the error within a two-year correction window.

Are there state income tax considerations on inherited IRA distributions?

Yes. Several states do not conform to federal retirement-income exclusions, meaning inherited IRA distributions that are fully taxable federally may also be taxable at the state level without any special treatment. Pennsylvania, for example, taxes inherited IRA distributions differently from original owner distributions. Verify your state's rules.

What is the Required Beginning Date for purposes of the 10-year rule analysis?

For most IRA owners, the RBD is April 1 of the year following the year they turn 73 (under SECURE 2.0, which raised the age from 72 effective for those born after 1950). Whether the original owner had passed that date at death determines whether annual RMDs apply inside your ten-year window.

What to Do Next

1. Confirm when the original IRA owner died and whether they had passed their Required Beginning Date. That single fact determines whether you owe annual distributions inside your ten-year window.
2. Pull your inherited IRA statements and calculate the remaining balance. If you have been taking only the minimum (or nothing, relying on the now-expired penalty waivers), model the tax cost of different distribution schedules across the remaining years.
3. Map your projected taxable income for each year in the distribution window. Identify years where there is room below a bracket threshold and consider front-loading distributions into those years.
4. If you also hold your own traditional IRA or 401(k), bring both accounts into the analysis together. Distributions from each interact in ways that are easy to optimize in advance and expensive to fix after the fact.
