What is an inherited IRA RMD?

When you inherit an Individual Retirement Account (IRA) from a deceased family member, friend, or anyone who named you as a beneficiary, you become subject to Required Minimum Distribution (RMD) rules. These rules determine how quickly you must withdraw money from the inherited account, which directly affects both your annual tax liability and long-term estate planning options.

An inherited IRA is sometimes called a beneficiary IRA and functions differently from a regular IRA that you open and contribute to yourself. The most important distinction is that you cannot make new contributions to an inherited IRA, and you must begin taking distributions according to IRS rules, regardless of your age.

Understanding these rules is essential because failing to take required distributions can result in substantial penalties, while taking distributions too quickly may push you into higher tax brackets unnecessarily. The rules are also different depending on your relationship to the original account owner, when they passed away, and whether they had already begun taking their own required minimum distributions.

The SECURE Act of 2019 fundamentally transformed inherited IRA rules, eliminating the popular "stretch IRA" strategy for most non-spouse beneficiaries. This legislation was one of the most significant changes to retirement account rules in decades and affected millions of Americans who expected to inherit retirement accounts.

How the SECURE Act changed everything

Before the SECURE Act (deaths before 2020)

Prior to the SECURE Act, beneficiaries could "stretch" distributions from an inherited IRA over their entire remaining life expectancy. This was an extraordinarily powerful estate planning tool because it allowed heirs to minimize their annual tax burden while keeping the bulk of the inherited assets growing tax-deferred for decades.

For example, a 30-year-old who inherited a 500,000IRAcouldtakerelativelysmallrequireddistributionsoverthenext50+yearsbasedontheirlifeexpectancy.Inthefirstyear,theRMDmightbelessthan500,000 IRA could take relatively small required distributions over the next 50+ years based on their life expectancy. In the first year, the RMD might be less than 10,000, leaving the remaining balance to continue growing tax-deferred. Over time, the account could potentially grow to several times its original value, even while taking required distributions.

This stretch strategy was particularly valuable for heirs in their peak earning years, as it allowed them to defer most of the inherited wealth until retirement when they might be in a lower tax bracket.

After the SECURE Act (deaths after 2019)

The SECURE Act dramatically shortened the distribution timeline for most beneficiaries by introducing the 10-year rule. Now, most non-spouse beneficiaries must withdraw the entire inherited IRA balance within 10 years of the original owner's death.

Beneficiary TypeDistribution Rule
SpouseCan treat as own IRA or use life expectancy method
Eligible Designated Beneficiary (EDB)Can still use life expectancy stretch
Non-Eligible Designated Beneficiary (NEDB)Must empty account within 10 years
Non-designated beneficiary (estates, charities)5-year rule typically applies

This change has profound tax implications. Instead of spreading distributions over 30, 40, or 50+ years, most beneficiaries must now compress all taxable distributions into just 10 years. For large inherited IRAs, this can push beneficiaries into higher tax brackets and result in significantly more taxes paid overall.

Understanding beneficiary categories

The IRS divides beneficiaries into several categories, each with different rules. Understanding which category you fall into is the first step in determining your distribution requirements.

Spouse beneficiaries

Surviving spouses have the most flexibility of any beneficiary type. They essentially have four different options for handling an inherited IRA:

Option 1: Treat the IRA as your own You can redesignate the inherited IRA as your own IRA. This is often the best choice for spouses under age 73 who don't need immediate access to the funds. You won't be required to take RMDs until you reach age 73, and you can name your own beneficiaries. This option provides maximum flexibility and continued tax-deferred growth.

Option 2: Roll over to your own IRA This is functionally similar to treating the IRA as your own. You transfer the inherited IRA funds into your existing IRA or a new IRA in your name. The funds become subject to normal IRA rules, including the 10% early withdrawal penalty if you're under 59½.

Option 3: Remain as beneficiary You can choose to remain as the beneficiary of the inherited IRA rather than treating it as your own. This option is particularly valuable if you're under age 59½ and need access to the funds, because distributions from an inherited IRA are not subject to the 10% early withdrawal penalty regardless of your age. RMDs are based on your life expectancy using the Single Life Expectancy Table.

Option 4: Take a lump sum distribution You can withdraw the entire balance at once. This is rarely advisable due to the massive tax hit, but may make sense in specific situations, such as when the inherited amount is small or you have significant losses to offset the income.

Eligible Designated Beneficiaries (EDBs)

Certain beneficiaries are exempt from the 10-year rule and can still use the more favorable life expectancy method. These Eligible Designated Beneficiaries include:

Minor children of the decedent: Children who have not yet reached the age of majority (21 in most states) can stretch distributions over their life expectancy. However, once they reach the age of majority, the 10-year clock starts. Importantly, this exception only applies to the decedent's own children, not grandchildren, nieces, nephews, or other minor relatives.

Disabled individuals: People who meet the IRS definition of disabled (unable to engage in substantial gainful activity due to a physical or mental condition expected to result in death or be of long, continued, and indefinite duration) can use the life expectancy method indefinitely.

Chronically ill individuals: Those certified by a licensed healthcare practitioner as being unable to perform at least two activities of daily living for at least 90 days, or requiring substantial supervision due to cognitive impairment, qualify for the stretch provision.

Individuals not more than 10 years younger than the decedent: This category often includes siblings, partners close in age, or older friends. The logic is that these beneficiaries have a similar life expectancy to the original owner anyway.

Non-Eligible Designated Beneficiaries (NEDBs)

Most beneficiaries fall into this category and are subject to the 10-year rule:

  • Adult children of the decedent
  • Grandchildren
  • Siblings (if more than 10 years younger)
  • Nieces and nephews
  • Friends
  • Domestic partners who aren't legally married
  • Most other individual beneficiaries

The 10-year rule explained

The 10-year rule is the default distribution requirement for Non-Eligible Designated Beneficiaries. While the basic concept is simple—empty the account within 10 years of the original owner's death—the details are more nuanced than many people realize.

Calculating your deadline

The 10-year period begins the year after the original owner's death. If the owner died in 2023, you have until December 31, 2033, to withdraw all funds from the inherited IRA.

Final Distribution Year=Year of Death+10\text{Final Distribution Year} = \text{Year of Death} + 10

Annual RMD requirements within the 10-year period

One of the most confusing aspects of the 10-year rule is whether you must take annual distributions or can simply wait until year 10 to withdraw everything. The answer depends on whether the original owner had already started taking their own RMDs:

Original Owner's StatusAnnual RMDs Required?Strategy
Died before reaching RMD age (under 73)NoFlexibility to distribute any amount in any year
Died after reaching RMD age (73+)YesMust take annual RMDs based on life expectancy, plus empty by year 10

This distinction is critical for tax planning. If the original owner died before starting RMDs, you have complete flexibility in how you distribute the funds over the 10-year period. You could take nothing for nine years and withdraw everything in year 10, or spread distributions evenly, or front-load or back-load distributions based on your income situation.

However, if the original owner had already started RMDs, you must take at least the minimum distribution each year, calculated using your life expectancy. The account must still be completely emptied by the end of year 10.

The 2025 RMD reset

The IRS caused significant confusion when implementing the SECURE Act's 10-year rule. Initially, many practitioners believed that beneficiaries subject to the 10-year rule had no annual RMD requirement regardless of when the original owner died. The IRS then proposed regulations indicating annual RMDs were required in certain situations.

Due to this confusion, the IRS waived the annual RMD requirement for 2021, 2022, 2023, and 2024 for beneficiaries subject to the 10-year rule. Starting in 2025, beneficiaries must begin taking annual RMDs if the original owner had already started their RMDs.

Year InheritedFirst Year RMDs Required
20202025
20212025
20222025
20232025
20242025

If you inherited an IRA from 2020-2024 and the decedent was taking RMDs, you need to start taking distributions in 2025. The good news is that missed RMDs during 2021-2024 will not be subject to penalties due to the IRS waiver.

RMD calculation methods

Basic formula

The formula for calculating your required minimum distribution from an inherited IRA is straightforward:

RMD=Account Balance (December 31 of prior year)Life Expectancy Factor\text{RMD} = \frac{\text{Account Balance (December 31 of prior year)}}{\text{Life Expectancy Factor}}

The account balance is determined as of December 31 of the year before the distribution year. For example, to calculate your 2025 RMD, you would use your account balance as of December 31, 2024.

Single Life Expectancy Table

The IRS provides the Single Life Expectancy Table (found in IRS Publication 590-B) for inherited IRA RMD calculations. Here are selected values from the table:

Beneficiary AgeLife Expectancy FactorBeneficiary AgeLife Expectancy Factor
2560.25531.6
3055.26027.2
3550.36523.0
4045.57019.2
4540.87515.6
5036.18012.3

Determining your initial life expectancy factor

For non-spouse beneficiaries, you look up your age in the year after the owner's death to find your initial life expectancy factor. This is true even if you didn't actually take a distribution that year.

Reducing life expectancy each year

For non-spouse beneficiaries using the life expectancy method, you don't look up a new factor each year. Instead, you reduce your initial factor by one for each subsequent year:

Current Year Factor=Initial FactorYears Since Initial Year\text{Current Year Factor} = \text{Initial Factor} - \text{Years Since Initial Year}

For example, if your initial factor was 40.8 (age 45), your factor in year 3 would be 40.8 - 2 = 38.8.

Spouse beneficiaries who choose to remain as beneficiaries (rather than treating the IRA as their own) can recalculate their life expectancy each year by looking up their current age in the table. This is more favorable because life expectancy doesn't decrease by exactly one year for each year of age.

Detailed example calculations

Example 1: NEDB when decedent was taking RMDs

Scenario:

  • Inherited IRA balance: $500,000 (as of December 31, 2024)
  • Beneficiary: Adult child, age 45 in the year after death
  • Year of death: 2023
  • Current year: 2025
  • Original owner was age 78 (had been taking RMDs)

Step-by-step calculation:

  1. Look up life expectancy for age 45: 40.8 years
  2. This becomes the initial factor (for 2024, year after death)
  3. For 2025 (year 2), reduce by 1: 40.8 - 1 = 39.8 years
  4. Calculate 2025 RMD: 500,000÷39.8=500,000 ÷ 39.8 = **12,563**

Additional requirements:

  • Must take at least $12,563 in 2025
  • Account must be completely emptied by December 31, 2033
  • Can take more than the RMD in any year

Example 2: NEDB when decedent had not started RMDs

Scenario:

  • Same as above, but original owner was age 65 (had not started RMDs)

Result:

  • No annual RMD requirement
  • Account must be emptied by December 31, 2033
  • Complete flexibility in timing and amounts
  • Strategic approach: 500,000÷9remainingyears500,000 ÷ 9 remaining years ≈ 55,556 per year

Tax planning consideration: If the beneficiary expects lower income in years 7-10, they might take minimal distributions in years 1-6 and larger distributions in years 7-10 when they're in a lower tax bracket.

Example 3: Spouse beneficiary treating IRA as own

Scenario:

  • Surviving spouse, age 58
  • Inherited IRA balance: $750,000
  • Chooses to treat as own IRA

Result:

  • No RMD required until age 73
  • If spouse needs funds before age 59½, would be subject to 10% early withdrawal penalty
  • Can name new beneficiaries
  • Maximum flexibility and continued tax-deferred growth

Example 4: Eligible Designated Beneficiary (disabled)

Scenario:

  • Disabled adult child, age 40
  • Inherited IRA balance: $300,000
  • Year of death: 2024

Calculation:

  1. Qualifies as EDB, can use life expectancy method
  2. Initial factor at age 41 (year after death): 44.8 years
  3. 2025 RMD: 300,000÷44.8=300,000 ÷ 44.8 = 6,696
  4. Can stretch distributions over entire life expectancy
  5. No 10-year rule applies

Penalties for missing RMDs

The IRS takes missed required minimum distributions seriously, though the penalties have become more forgiving under recent legislation.

SECURE 2.0 Act penalty changes

The SECURE 2.0 Act of 2022 reduced the penalty for missed RMDs:

SituationPenalty Rate
Missed RMD (standard penalty)25% of the amount not withdrawn
Corrected within 2 years during correction window10% of the amount not withdrawn
Previous rule (before 2023)50% of the amount not withdrawn

How to correct a missed RMD

If you realize you've missed an RMD, take these steps:

  1. Take the missed distribution immediately. Withdraw the amount you should have taken as soon as possible.

  2. File Form 5329 with your tax return. This form reports the missed RMD and calculates the penalty.

  3. Request a penalty waiver by attaching a letter explaining the reasonable cause for missing the distribution. The IRS frequently waives penalties when the shortfall was due to reasonable error and you've taken steps to remedy the situation.

  4. Pay any applicable penalty if the waiver is not granted.

Common reasonable causes that may qualify for penalty relief include illness, death of a family member, natural disasters, postal delays, or errors by financial institutions.

Tax planning strategies for inherited IRAs

Smart distribution planning can save thousands of dollars in taxes over the distribution period. Here are key strategies to consider:

Spread distributions to manage tax brackets

Instead of taking large distributions in some years and nothing in others, consider spreading distributions relatively evenly to avoid pushing yourself into higher tax brackets. Model your expected income for each year of the 10-year period and plan distributions accordingly.

Coordinate with other income sources

Consider how inherited IRA distributions interact with your other income:

  • Years with large capital gains might not be ideal for big IRA distributions
  • If you're between jobs, that might be a good year for larger distributions
  • Years when you're maximizing retirement contributions might handle additional IRA income better due to the deduction

Consider state tax implications

Some states don't tax retirement income at all, or have lower rates than federal taxes. If you're planning to relocate to a lower-tax state, it might make sense to delay larger distributions until after the move.

Bunch deductions strategically

If you itemize deductions, consider bunching charitable contributions or other deductible expenses in years when you take larger inherited IRA distributions to offset the additional income.

Roth conversion consideration for spouses

Spouses who treat an inherited IRA as their own might consider converting some or all to a Roth IRA over time. This accelerates taxes but can provide tax-free growth and distributions later, plus eliminate future RMD requirements.

Inherited Roth IRAs

Roth IRAs have special rules that make them particularly valuable to inherit:

Key differences from traditional IRAs

  • Qualified distributions are completely tax-free
  • The 10-year rule still applies for non-eligible designated beneficiaries
  • No annual RMD requirement during the 10-year period
  • Growth continues tax-free until distributed

The 5-year rule for Roth IRAs

For distributions from an inherited Roth IRA to be fully tax-free, the original owner must have had a Roth IRA open for at least 5 years. The 5-year period starts January 1 of the year of the first contribution or conversion to any Roth IRA owned by the decedent.

If the 5-year requirement isn't met, earnings (but not contributions or conversions) may be taxable when distributed.

Optimal strategy for inherited Roth IRAs

Because Roth IRA distributions are tax-free and there's no annual RMD requirement (just the 10-year deadline), the optimal strategy is typically to leave the money in the account as long as possible to maximize tax-free growth. Wait until year 10 to take distributions, unless you need the funds sooner.

Special situations

Multiple beneficiaries

When multiple people inherit a single IRA, they can split it into separate inherited IRAs by December 31 of the year following the owner's death. This is strongly recommended because:

  • Each beneficiary can use their own life expectancy for calculations
  • Distribution decisions are independent
  • Tax planning can be tailored to individual situations
  • Avoids conflicts between beneficiaries with different financial needs

Trust beneficiaries

When an IRA is left to a trust rather than individuals directly, special rules apply:

See-through trusts that meet certain requirements allow the IRS to "look through" to the individual beneficiaries for determining distribution rules. The trust must be valid under state law, irrevocable upon the owner's death, and the beneficiaries must be identifiable.

Non-qualifying trusts that don't meet see-through requirements are generally subject to accelerated distribution rules, typically requiring complete distribution within 5 years.

Trust beneficiaries face complex rules and should always consult with an estate attorney and tax professional.

Estate as beneficiary

When an IRA has no designated beneficiary and passes through the estate, the 5-year rule typically applies if the owner died before starting RMDs. If the owner had started RMDs, distributions can be based on the owner's remaining life expectancy.

Common mistakes to avoid

Missing the December 31 deadline: RMDs must be taken by December 31 each year. There's no grace period for inherited IRAs.

Not separating accounts when there are multiple beneficiaries: Failing to split an inherited IRA by December 31 of the year after death means all beneficiaries must use the oldest beneficiary's life expectancy.

Spouse treating IRA as own when under 59½: This triggers the 10% early withdrawal penalty on any distributions before age 59½.

Ignoring state tax implications: State taxes can significantly affect total taxes owed on distributions.

Waiting too long under the 10-year rule: Taking the entire distribution in year 10 may push you into much higher tax brackets than spreading distributions over multiple years.

Summary

Inherited IRA RMD rules have become significantly more complex since the SECURE Act. Key points to remember:

  1. The SECURE Act changed everything for deaths after 2019, eliminating the stretch IRA for most beneficiaries
  2. The 10-year rule now applies to most non-spouse beneficiaries, requiring complete distribution within 10 years
  3. Annual RMDs may be required during the 10-year period if the original owner had started taking RMDs
  4. 2025 is the first year that annual RMDs are required for those who inherited from 2020-2024
  5. Spouse beneficiaries have the most flexibility with four different options
  6. Eligible Designated Beneficiaries (minor children, disabled, chronically ill, those close in age) can still stretch distributions
  7. The penalty for missing RMDs is 25%, reduced to 10% if corrected quickly
  8. Tax planning is essential to minimize the overall tax burden over the distribution period
  9. Inherited Roth IRAs offer tax-free growth and distributions, making them especially valuable

Given the complexity of these rules and the significant tax implications, consulting with a qualified tax professional or financial advisor is strongly recommended. They can help you develop a distribution strategy tailored to your specific situation, other income sources, and overall financial goals.
