Inherited IRA Tax Treatment for Beneficiaries

The tax burden on an inherited IRA depends on two factors: whether you inherited a traditional (pretax) or Roth (post-tax) account, and which category of beneficiary you fall into. Spouses have the most flexibility; non-spouse beneficiaries face stricter distribution windows and ongoing income tax.

Spouse vs. non-spouse beneficiary: the fundamental split

The IRS treats inherited IRAs very differently depending on your relationship to the deceased account owner. A spouse has rights a sibling, child, or unrelated beneficiary does not. This distinction is the entry point to understanding your tax obligation.

Spouse beneficiary rules

If you are the surviving spouse, you can elect to treat the IRA as your own. This election is the most tax-efficient path for most spouses because it resets the clock: you become the new owner and can delay distributions until your own required minimum distributions (RMDs) begin at age 73 (as of 2023). You also gain full access to the account, including contributions and conversions, without immediate distribution pressure.

Alternatively, a spouse can keep the account as an “inherited IRA” in the deceased’s name and take distributions as a beneficiary. This approach is slower to liquidate but offers strategic flexibility if you do not need the money immediately.

Non-spouse beneficiary rules

Non-spouse beneficiaries—adult children, siblings, grandchildren, trusts, or friends—must distribute the inherited account under different rules. The SECURE Act (2019) and its 2022 amendment, SECURE 2.0, reshaped the timeline: most non-spouse beneficiaries must empty the account within ten years after the owner’s death. Within that ten-year window, the IRS does not mandate annual minimum distributions. However, by December 31st of the tenth year, the entire balance (including earnings) must be withdrawn.

A few narrow exceptions (spouse, disabled beneficiary, chronically ill beneficiary, or a beneficiary within ten years of the deceased’s age) can use life-expectancy-based distributions instead, stretching the timeline over decades.

Traditional IRA inheritance: all distributions are taxable

When a beneficiary inherits a traditional IRA, every withdrawal is ordinary income to the beneficiary. The deceased owner never paid tax on the contributions (they were deductible) or the earnings. The beneficiary now bears that tax liability.

If the deceased owner had begun RMDs before death, the beneficiary must take at least the distribution the owner would have taken in the year of death. For subsequent years, the ten-year rule applies (or life-expectancy for eligible beneficiaries).

The traditional IRA does not distinguish between contributions, conversions, and earnings when distributing to a beneficiary. It is all pretax money, so it is all taxable at the recipient’s ordinary income tax rate. This can lead to a large bunching of income in a single year if the beneficiary withdraws a lump sum.

Roth IRA inheritance: tax-free to eligible beneficiaries

A beneficiary who inherits a Roth IRA has a key advantage: the earnings portion of the account is often tax-free. This is true as long as the Roth account was owned for at least five tax years before the owner’s death. If it was not, earnings are taxable to the beneficiary; contributions and conversions remain tax-free.

The five-year rule is tied to the account as a whole, not the beneficiary. If the owner opened the Roth in 2020 and died in 2024, the five years have elapsed, and any beneficiary gets tax-free earnings. If they opened it in 2023 and died in 2024, the account is not “seasoned,” and beneficiary distributions of earnings face tax.

Non-spouse beneficiaries inherit the same ten-year distribution window as with a traditional IRA. The advantage is that they can access contributions and conversions tax-free throughout, and if the five-year rule is satisfied, earnings are also tax-free—even though they must withdraw the full balance by year ten.

Inherited 401(k) plans: stricter withholding

An inherited 401(k) (or other employer plan) follows similar tax rules but with a wrinkle: the plan trustee may impose automatic 20% federal withholding on distributions. A spouse who rolls the plan into an inherited IRA or treats it as their own can avoid this withholding. Non-spouse beneficiaries cannot roll to their own IRA; they must take distributions directly from the plan, triggering withholding unless the plan allows transfers to a beneficiary IRA.

The order of withdrawal and planning

When you inherit a Roth IRA, the withdrawal ordering rule still applies: contributions and conversions come out first (tax-free), then earnings. You cannot cherry-pick earnings to leave behind. However, because most of the account under normal circumstances comes out tax-free (if the five-year rule is met), this ordering is less painful than it would be for the account owner.

For a traditional IRA, there is no special ordering—all distributions are taxable regardless of composition.

Calculating the tax burden: examples

Example 1: Non-spouse inherits a traditional IRA. Uncle Joe dies, leaving a $500,000 traditional IRA to his nephew. The nephew has ten years to empty it. If he withdraws $50,000 per year, each withdrawal is fully taxable at his marginal tax rate (say, 32%). He owes about $16,000 in tax per withdrawal, or $160,000 over ten years (ignoring growth). If he waits and takes a lump sum of $500,000 in year ten, he faces a much higher marginal rate, potentially 37%, and state taxes.

Example 2: Spouse beneficiary with a Roth. Jane’s husband dies, leaving her a $300,000 Roth IRA that was opened in 2010. She elects to treat it as her own. The five-year rule is satisfied. She can withdraw the entire balance tax-free if she chooses, or leave it untouched until age 73 (her RMD age), at which point she can spread distributions. She has no forced distribution timeline.

Example 3: Non-spouse, Roth with inadequate seasoning. Matt inherits a Roth IRA opened in 2023 by his mother; she dies in 2024. The account has $100,000 in contributions and $5,000 in earnings. The five-year rule is not met (only 1.5 years old). Matt can withdraw the $100,000 contributions tax-free. The $5,000 earnings are taxable as ordinary income. He must empty the account by the end of year ten.

Income bunching and tax management

Beneficiaries often face a trade-off: take modest annual distributions (staying in a lower bracket) or take a lump sum (simplifying bookkeeping but risking a higher bracket). The inherited IRA cannot be divided between beneficiaries after inheritance (except through careful trust structuring), so timing decisions rest with a single person.

Some beneficiaries pair inherited-IRA withdrawals with low-income years, investment losses, or tax-loss harvesting in other accounts to minimize the impact. Others accept the higher tax bill as a one-time event.
