Inherited IRA Rules: 10-Year Deadline & Tax Strategies

Inherited IRA Distribution Rules: The 10-Year Deadline, Pro-Rata Trap, and Tax-Efficient Withdrawal Strategies Under SECURE 2.0

Inheriting an IRA can create a surprisingly complicated tax problem. You may have up to 10 years to empty the account, but the best withdrawal schedule depends on the original owner’s date of death, RMD status, the type of IRA, your beneficiary classification, and your expected taxable income.

For many non-spouse beneficiaries, the central rule is straightforward: the inherited IRA must be empty by December 31 of the tenth year after the owner’s year of death. The difficult decisions occur inside that window. Some beneficiaries must take annual required minimum distributions, or RMDs, while others can choose when to withdraw. Traditional IRA distributions can increase taxable income, and poorly documented after-tax contributions can cause the same dollars to be taxed twice.

This article explains the federal rules generally. It is not individualized tax, financial, or legal advice.

Inherited IRA Distribution Rules at a Glance

The SECURE Act generally placed most non-spouse beneficiaries who inherit an IRA from someone dying after 2019 under a 10-year distribution rule. SECURE 2.0 subsequently changed several retirement rules, including the ages at which account owners begin their own RMDs, but it did not eliminate the inherited-account deadline.

• Traditional inherited IRA: Distributions are generally ordinary taxable income, except for any properly documented after-tax basis.
• Inherited Roth IRA: Qualified distributions are generally tax-free, although the account may still have to be emptied within 10 years.
• Non-spouse inherited IRA: The beneficiary generally must keep the assets in a properly titled inherited IRA and cannot roll them into or combine them with the beneficiary’s own IRA.
• Spouse-inherited IRA: A surviving spouse has additional options, potentially including treating the IRA as the spouse’s own, completing a spousal rollover, or remaining an inherited-account beneficiary.

Inherited IRA withdrawals generally qualify for an exception to the 10% additional tax on early distributions, even when the beneficiary is younger than age 59½. That exception does not make a traditional IRA withdrawal income-tax-free. The taxable portion still enters the beneficiary’s federal gross income and may also be subject to state income tax.

The principal planning questions are whether annual RMDs apply, how withdrawals will affect tax brackets and income-based costs, whether the account contains after-tax basis, and how much must be distributed before the year-10 deadline.

Who Must Follow the 10-Year Inherited IRA Rule?

Most individual beneficiaries who do not qualify as “eligible designated beneficiaries” are subject to the 10-year rule. These non-eligible designated beneficiaries commonly include adult children, siblings, nieces, nephews, and friends.

Eligible designated beneficiaries

An eligible designated beneficiary may qualify to calculate distributions using a life-expectancy method instead of immediately becoming subject to the standard 10-year rule. This category generally includes:

• A surviving spouse.
• The deceased owner’s minor child, generally until the child reaches age 21. A 10-year distribution period generally begins at that point.
• A disabled individual who meets the applicable tax-law definition.
• A chronically ill individual who meets the applicable statutory requirements.
• An individual who is not more than 10 years younger than the deceased owner.

These exceptions are not interchangeable. Surviving spouses have choices that other eligible designated beneficiaries do not have, while the exception for a minor applies only to the deceased owner’s child—not to every minor named as a beneficiary.

Documentation requirements and special rules can be important for disabled and chronically ill beneficiaries. Trusts named as beneficiaries also require separate analysis. The result may depend on whether the trust qualifies as a see-through trust, the trust’s terms, and the identities of its beneficiaries.

IRAs inherited from owners who died before January 1, 2020, generally remain governed by the pre-SECURE Act rules. Beneficiaries already using a life-expectancy schedule should not automatically switch to the newer 10-year framework without confirming which rules apply.

How the 10-Year Deadline Works Under SECURE 2.0

An inherited IRA subject to the 10-year rule must generally be fully distributed by December 31 of the tenth calendar year following the owner’s year of death.

Example: If an IRA owner dies during 2026 and the beneficiary is subject to the 10-year rule, year one is 2027 and year ten is 2036. The inherited account generally must have a zero balance by December 31, 2036.

The deadline does not necessarily mean the beneficiary can ignore the account until year ten. Whether annual distributions are also required generally depends on whether the original owner died before or on or after the owner’s required beginning date.

Owner died on or after the required beginning date

When the owner died on or after the required beginning date, a beneficiary subject to the 10-year rule generally must take annual life-expectancy-based RMDs during years one through nine and distribute the entire remaining balance by the end of year ten.

The IRS provided transition relief from the excise tax for certain missed annual inherited-account RMDs for 2020 through 2024. That relief addressed specified annual distributions during the transition period; it did not extend the year-10 deadline or waive other distributions that were otherwise required.

The transition relief ended with the 2024 tax year. For 2025 and subsequent years, annual inherited-account RMDs are mandatory when the annual-RMD rule applies. Beneficiaries in this category should obtain the applicable calculation rather than relying solely on the final year-10 deadline.

If the owner had not taken the full RMD required for the year of death, the beneficiary may also need to complete that year-of-death RMD. This obligation should be checked promptly because it is separate from the beneficiary’s RMDs in later years.

Owner died before the required beginning date

If the owner died before the required beginning date, a non-eligible designated beneficiary generally does not have annual RMDs during years one through nine. The beneficiary may choose the timing and amount of withdrawals, provided the account is completely distributed by the end of year ten.

The applicable starting age is not always simply “age 73.” It depends on the owner’s birth year and the law in effect. Confirm both the owner’s age and whether the owner had reached the technical required beginning date.

For inherited Roth IRAs, the original owner is generally treated as having died before the required beginning date because Roth IRA owners do not take lifetime RMDs. A beneficiary subject to the 10-year rule can therefore generally leave the account intact during years one through nine but must empty it by the end of year ten.

Traditional vs. Roth Inherited IRA Tax Treatment

Traditional inherited IRAs

Distributions from a traditional inherited IRA are generally included in ordinary taxable income. For example, a fully taxable $50,000 withdrawal can increase adjusted gross income by $50,000. That increase may affect the beneficiary’s marginal tax rate, state taxes, estimated-tax obligations, deductions, credits, and income-based Medicare premiums.

The 10% early-distribution tax generally does not apply to distributions made to a beneficiary after the owner’s death. A non-spouse beneficiary should take distributions directly from the properly titled inherited account and should not attempt a rollover into a personally owned IRA.

Assets remaining in the inherited account can continue growing tax-deferred during the distribution period. Deferral can be valuable, but allowing nearly the entire balance to accumulate for a final-year withdrawal can create a much larger taxable-income spike.

Inherited Roth IRAs

Qualified Roth IRA distributions are generally free from federal income tax. The beneficiary should nevertheless confirm when the decedent first funded a Roth IRA because the original owner’s Roth five-year qualification period generally carries over to the inherited account.

If the five-year requirement has not been satisfied, withdrawn earnings may require additional analysis. Roth contributions are generally recovered before earnings, but the custodian may not have complete historical contribution information. Obtain the decedent’s records rather than assuming every dollar is automatically qualified.

A qualified inherited Roth IRA can often be left invested until late in the 10-year period to preserve potential tax-free growth. Earlier distributions may still be reasonable when the beneficiary needs cash, wants to reduce investment risk, or has another higher-priority use for the money.

The Inherited IRA Pro-Rata Trap: Basis, Form 8606, and Multiple Accounts

After-tax basis arises when an IRA owner makes nondeductible contributions to a traditional IRA. Those contributions were already taxed, so the corresponding portion of a later distribution should not be taxed again. The beneficiary, however, must be able to substantiate the decedent’s remaining basis.

A beneficiary generally cannot instruct the custodian to distribute only the tax-free basis while leaving all taxable dollars invested. Each distribution is divided between taxable and nontaxable amounts under the applicable pro-rata calculation.

In simplified form:

Tax-free percentage = remaining after-tax basis ÷ total applicable IRA value

Example: Assume an applicable inherited IRA pool contains $20,000 of remaining basis and has a total value of $100,000 for the calculation. The tax-free percentage is 20%. A $10,000 distribution would be approximately $2,000 nontaxable and $8,000 taxable, subject to the precise Form 8606 calculation, account values, distributions, and any other required adjustments.

The aggregation rules need careful handling. For a taxpayer’s personally owned IRAs, the pro-rata calculation generally considers that person’s traditional, SEP, and SIMPLE IRAs. An inherited IRA with basis is generally handled separately from the beneficiary’s personally owned IRAs, and inherited IRAs received from different decedents may also require separate calculations.

The practical lesson is to coordinate all relevant accounts and Forms 8606 without automatically combining every IRA into a single denominator. A tax professional can determine the correct grouping based on account ownership, the source of the inherited assets, and the decedent’s basis records.

Useful supporting records include:

• The decedent’s prior Forms 8606.
• Tax returns reporting nondeductible traditional IRA contributions.
• Account statements showing contributions, conversions, and distributions.
• Records of any distributions taken during the year of death.
• Documents establishing the Roth IRA’s original funding date.
• The beneficiary’s separate Forms 8606 for personally owned IRAs.

Custodians track account values and distributions, but they may not know the decedent’s remaining after-tax basis. Without reliable records, a beneficiary could inadvertently report the entire distribution as taxable and pay tax twice on the same dollars.

Tax-Efficient Withdrawal Strategies for Years 1 Through 10

No single withdrawal pattern is best for every beneficiary. The objective is generally to manage total taxes over the full distribution period while satisfying annual RMDs, when applicable, and meeting the final deadline.

Equal annual withdrawals

Dividing the initial balance by 10 provides a simple planning baseline. For example, a beneficiary might initially model $50,000 per year from a $500,000 inherited traditional IRA. A more useful projection recalculates the schedule annually for investment returns, required distributions, changing tax brackets, and other income.

This approach can reduce the risk of a final-year tax spike, although it may not take full advantage of unusually low-income years.

Front-loading distributions

Larger early withdrawals may make sense when the beneficiary currently has low taxable income but expects higher wages, business profits, pensions, personal RMDs, or Social Security income later. Front-loading may also reduce exposure to possible future tax-rate increases, although future tax law cannot be predicted reliably.

Potential planning windows include a sabbatical, a year with deductible business losses, an early-retirement period, or the years between retirement and claiming Social Security. The beneficiary should still model how a larger withdrawal affects state taxes, credits, deductions, and estimated payments.

Back-loading distributions

Smaller early withdrawals and larger later withdrawals may be reasonable when current income is unusually high and is expected to decline. This approach also preserves more tax-deferred or tax-free growth inside the account.

Back-loading requires regular monitoring. Strong investment returns can leave a much larger balance than expected, and annual RMDs must still be taken when the owner died on or after the required beginning date.

Waiting until year ten

A final-year withdrawal may be effective for a qualified inherited Roth IRA because it maximizes the time available for potential tax-free growth. For a traditional inherited IRA, however, waiting can compress years of taxable distributions into a single return.

A large withdrawal may push part of the distribution into higher federal and state tax brackets. For beneficiaries enrolled in Medicare, higher modified adjusted gross income can also increase income-related monthly adjustment amounts, or IRMAA. Medicare generally uses tax-return information from two years earlier, so a year-10 distribution may affect premiums later.

Model the entire tax picture

An annual projection should include wages, self-employment income, capital gains, pensions, Social Security, deductions, credits, state taxes, investment income, and distributions from other retirement accounts. It should also estimate withholding or quarterly payments to reduce the risk of an underpayment penalty.

Charitably inclined beneficiaries should not assume that a qualified charitable distribution, or QCD, is available from an inherited IRA. QCD rules generally apply to an eligible IRA owner, and there is not clear, broadly applicable support for a non-spouse beneficiary treating a direct payment from an inherited IRA as a QCD. A beneficiary may instead consider taking a taxable distribution and making a separate charitable gift, but the tax result depends on deduction eligibility and other circumstances. Obtain professional advice before treating any inherited-account transfer as a QCD.

What to Do Next With an Inherited IRA

1. Confirm the facts. Record the owner’s date of death, birth date, account type, required beginning date, year-of-death RMD status, and your beneficiary classification.
2. Title the account correctly. A non-spouse beneficiary should generally use a properly titled inherited IRA and should not roll the assets into a personally owned IRA.
3. Confirm both distribution requirements. Ask whether annual RMDs apply and obtain written confirmation of the final December 31 year-10 deadline.
4. Check the year-of-death RMD. Determine whether the owner completed it and whether a beneficiary must withdraw any shortfall.
5. Separate beneficiary accounts promptly. When multiple beneficiaries are named, separate inherited accounts generally should be established by December 31 of the year following the owner’s death to preserve beneficiary-specific treatment where available.
6. Locate basis records. Obtain prior Forms 8606, nondeductible contribution records, Roth funding history, conversion records, and information about earlier distributions.
7. Run a multiyear projection. Compare equal, front-loaded, and back-loaded withdrawals under reasonable income and investment assumptions.
8. Plan for payments. Include federal and state withholding or estimated-tax payments when selecting a distribution amount.
9. Revisit the plan annually. Income, portfolio values, tax law, Medicare status, and personal circumstances can change before year ten.

The most important practical step is to avoid treating the 10-year rule as permission to postpone planning. Confirm the annual distribution requirements early—especially now that the 2020-through-2024 penalty relief has ended—preserve evidence of after-tax basis, and choose withdrawals using annual federal and state tax projections. A qualified tax professional or financial planner familiar with inherited retirement accounts can help apply the rules to the specific estate, beneficiary, and account involved.
