Does an Inherited IRA Continue to Grow? (w/Examples) + FAQs

Yes, an Inherited IRA continues to grow. The assets inside keep earning interest, dividends, and capital gains on a tax-deferred basis (or tax-free inside an Inherited Roth IRA) until the money is withdrawn. But the growth window is no longer unlimited for most people. The SECURE Act of 2019 and the follow-up SECURE 2.0 Act of 2022 compressed the payout period, which means the compounding clock runs faster than it used to.

The governing rule is Internal Revenue Code §401(a)(9), which sets required minimum distribution (RMD) deadlines for beneficiaries. The IRS Final Regulations issued in July 2024 confirm that most non-spouse beneficiaries must empty the account within 10 years, and many must take annual RMDs during that window. Missing an RMD triggers a 25% excise tax under IRC §4974, which drops to 10% if corrected on time.

According to Cerulli Associates, roughly $124 trillion in wealth will transfer through 2048, and a large share will flow through Inherited IRAs. That scale makes understanding the growth mechanics a financial survival skill, not a niche concern.

What an Inherited IRA Actually Is

An Inherited IRA (also called a Beneficiary IRA) is a retirement account that holds assets passed from a deceased owner to a named beneficiary. The account is titled in a specific way — for example, “Jane Doe, deceased, IRA FBO John Doe, beneficiary” — as required by IRS Publication 590-B. The titling matters because a mistitled account can be treated as a full taxable distribution in the year of death.

The account keeps its tax character. A Traditional Inherited IRA grows tax-deferred, and every dollar withdrawn counts as ordinary income under IRC §408(d). A Roth Inherited IRA grows tax-free, and qualified withdrawals are fully tax-free if the original owner’s Roth was open for at least five years, as explained in the IRS Roth IRA guidance.

The beneficiary cannot add new contributions to the Inherited IRA. The only money inside is what the decedent left, plus earnings. The consequence of trying to contribute is that the deposit becomes an excess contribution subject to a 6% annual penalty under IRC §4973. A common misconception is that you can “merge” an Inherited IRA into your own IRA. Only a surviving spouse can do that through a spousal rollover, and the election is irrevocable once exercised.

Tax-Deferred vs. Tax-Free Growth

Tax-deferred growth means the IRS does not tax dividends, interest, or capital gains inside the Traditional Inherited IRA each year. The tax hits only when money leaves the account. The consequence is faster compounding because 100% of earnings stay invested, but the beneficiary owes ordinary income tax (not capital gains rates) on every distribution.

Tax-free growth inside an Inherited Roth IRA is even more powerful. The earnings escape federal income tax entirely if the five-year rule is met. A real example is Carlos, age 40, who inherits a $300,000 Roth from his mother. If the account earns 7% annually for 10 years, it grows to roughly $590,000, and Carlos owes zero federal income tax on the full distribution.

A common misconception is that Roth Inherited IRAs have no RMDs. Under the 2024 Final Regulations, non-spouse Roth beneficiaries must still empty the account within 10 years, even though Roth owners themselves never had lifetime RMDs under SECURE 2.0 Section 325.

Why the Account Keeps Growing

The investments inside the Inherited IRA do not freeze on the date of death. Stocks keep paying dividends, bonds keep paying interest, and mutual funds keep reinvesting. The custodian — Fidelity, Schwab, Vanguard, or another — simply retitles the account and continues to execute trades as directed by the new beneficiary.

The beneficiary chooses the investments. A conservative 34-year-old named David might shift a $500,000 Inherited IRA into a 60/40 stock-bond mix, while his 78-year-old aunt would likely prefer a 30/70 allocation. Both strategies are legal, and both accounts keep growing between distributions.

The consequence of leaving money fully invested until year 10 is maximum compounding, but it also means a massive taxable distribution in the final year. That lump sum can push a beneficiary into the 37% federal bracket under IRC §1, which is why spreading withdrawals often beats a final-year dump.

The Three Beneficiary Classes Under the SECURE Act

The SECURE Act created three beneficiary categories, and the category you fall into controls how long the account can keep growing. The IRS Final Regulations of July 2024 locked in the mechanics after years of confusion.

The rule exists because Congress wanted to stop the “stretch IRA” strategy, where a young beneficiary could drain an Inherited IRA over a 50-year life expectancy and compound the tax deferral across generations. The consequence is that most non-spouse beneficiaries now have a strict 10-year growth window.

A common misconception is that the 10-year rule always means “no withdrawals until year 10.” The Final Regulations clarify that if the decedent died after their required beginning date (RBD), the beneficiary must take annual RMDs and empty the account by year 10.

Eligible Designated Beneficiaries (EDBs)

An Eligible Designated Beneficiary is the most favored class. Under IRC §401(a)(9)(E)(ii), EDBs include surviving spouses, minor children of the decedent (until age 21), disabled individuals, chronically ill individuals, and beneficiaries not more than 10 years younger than the decedent.

EDBs can stretch distributions over their own life expectancy using the Single Life Table in Treasury Regulation §1.401(a)(9)-9. This means decades of continued tax-deferred growth. A real example is Maria, age 52, who is only 8 years younger than her late brother. Because she is “not more than 10 years younger,” she qualifies as an EDB and can stretch the $400,000 Inherited IRA across her 33.4-year life expectancy.

The consequence of missing the EDB documentation deadline — September 30 of the year after death — is loss of EDB status and forced default into the 10-year rule. A common misconception is that adult children automatically qualify as EDBs; they do not, unless they are disabled or chronically ill under IRC §72(m)(7).

Designated Beneficiaries (10-Year Rule)

A Designated Beneficiary is any named human who is not an EDB. Adult children, grandchildren, nieces, nephews, and most friends fall into this bucket. The account must be fully distributed by December 31 of the 10th year after the year of death, per IRC §401(a)(9)(H).

If the decedent died before their RBD (generally age 73 under SECURE 2.0), the beneficiary can skip annual RMDs and wait until year 10. If the decedent died after their RBD, the 2024 Final Regulations require annual RMDs during years 1 through 9, plus a full drain in year 10. The IRS waived the penalty for missed 2021–2024 RMDs under Notice 2024-35, but enforcement began in 2025.

The consequence of ignoring annual RMDs in 2025 and later is the 25% excise tax on the shortfall, reduced to 10% if corrected within the two-year correction window under SECURE 2.0 Section 302.

Non-Designated Beneficiaries

A Non-Designated Beneficiary is typically an estate, a non-qualifying trust, or a charity. Because these entities have no “life,” the IRS applies either the 5-year rule (if the owner died before RBD) or the “ghost life expectancy” method based on the decedent’s remaining life expectancy (if death occurred after RBD).

The 5-year rule forces full distribution by December 31 of the fifth year after death. The consequence is a much shorter growth window and a potentially huge tax bill compressed into a short period. A real example is the Smith Family Trust, a non-qualifying trust that inherits a $600,000 IRA from 68-year-old Robert; the trust must empty the account by year five, and the trust’s 37% compressed bracket under IRC §1(e) swallows much of the growth.

A common misconception is that all trusts are treated the same. A properly drafted “see-through” trust that meets the four requirements of Treas. Reg. §1.401(a)(9)-4 can qualify as a Designated Beneficiary and use the 10-year rule.

How the 10-Year Rule Affects Growth (Real Math)

The 10-year rule does not stop growth — it caps the time growth can happen tax-deferred. Inside that window, the money keeps compounding. Let’s walk through three scenarios with real numbers using a starting balance of $500,000 and an assumed 7% annual return.

Withdrawal Strategy 10-Year Outcome
Wait until year 10, take full lump sum ~$983,576 withdrawn, likely taxed at 37% federal
Take equal annual distributions (~$71,000/yr) ~$712,000 total withdrawn, spread across lower brackets
Take RMDs only (if required), then lump-sum year 10 ~$850,000 total, middle-ground tax efficiency

Scenario 1: The Patient Heir

Jennifer, age 45, inherits a $500,000 Traditional IRA from her father who died at age 68 (before his RBD). Because her father died before RBD, Jennifer can skip annual RMDs and let the account grow untouched. At 7% annual growth, the account reaches about $983,576 by year 10.

The consequence is that Jennifer takes a single massive distribution in year 10, which pushes her into the top 37% federal bracket. She also may trigger the 3.8% Net Investment Income Tax indirectly by increasing her AGI. She nets roughly $580,000 after federal and state tax.

Scenario 2: The Balanced Drawdown

Action Tax Outcome
Jennifer withdraws ~$71,000 each year for 10 years Stays in 24% bracket most years
Account still grows on the remaining balance Total withdrawn: ~$710,000
Effective federal tax: ~22% blended Net after tax: ~$554,000

Scenario 3: The Roth Advantage

Carlos, age 40, inherits a $300,000 Roth IRA. He lets it grow for the full 10 years at 7%, reaching about $590,000. Because qualified Roth distributions are tax-free under IRC §408A(d), Carlos keeps every dollar.

The consequence of this strategy is maximum tax-free compounding. The common misconception is that Roth heirs must take annual RMDs — they do not, because the original Roth owner is deemed to have died before their RBD for RMD purposes, per the July 2024 Final Regulations.

Spousal Inherited IRAs: A Different Universe

A surviving spouse has options no other beneficiary gets. Under IRC §408(d)(3)(C)(ii)(II), a spouse can roll the inherited assets into their own IRA, treat the IRA as their own, or keep it as an Inherited IRA. Each choice changes the growth timeline.

The spousal rollover resets the account into the surviving spouse’s name. From that point, the account follows the spouse’s own RMD schedule starting at age 73 under SECURE 2.0 Section 107. The consequence is decades of additional tax-deferred growth, but the spouse loses the ability to withdraw penalty-free before age 59½.

A common misconception is that a spouse must roll over immediately. The spouse can wait, and SECURE 2.0 Section 327 (effective 2024) lets the surviving spouse elect to be treated as the deceased spouse for RMD purposes, which is often favorable when the deceased was younger.

Example: The Widow’s Choice

Susan, age 60, inherits a $1,000,000 IRA from her 75-year-old husband. If she rolls it into her own IRA, she avoids RMDs until her own age 73, gaining 13 more years of tax-deferred growth. At 7% annual return, the account reaches about $2.4 million before her first RMD.

If Susan keeps it as an Inherited IRA, she must take annual RMDs immediately based on her husband’s schedule. The consequence is less compounding, but she can access the money before age 59½ without the 10% early-withdrawal penalty under IRC §72(t)(2)(A)(ii).

State Tax Treatment of Inherited IRA Growth

Federal rules are uniform, but state taxes vary wildly. The growth inside the account is not taxed by states while it stays in the IRA, but distributions are another story.

Pennsylvania generally exempts Inherited IRA distributions from state income tax for beneficiaries over 59½ under the commonwealth’s retirement income exclusion. Illinois similarly excludes qualified retirement distributions. Florida, Texas, Tennessee, and six other states have no state income tax, so growth and distributions are entirely state-tax-free.

California, New York, and New Jersey fully tax Inherited IRA distributions as ordinary income. The New Jersey tax treatment is especially painful because New Jersey did not allow a deduction for the original contributions, so beneficiaries must track basis to avoid double taxation.

Community Property Wrinkles

In community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — a surviving spouse may already own half the IRA. The consequence is that only half the account is technically “inherited,” and the other half belongs to the spouse outright under state law. A common misconception is that community property law overrides federal IRA beneficiary designations. It does not — Egelhoff v. Egelhoff, 532 U.S. 141 (2001), confirmed that ERISA and federal IRA beneficiary rules preempt conflicting state law.

Creditor Protection of Inherited IRA Growth

The growth inside an Inherited IRA is not protected from the beneficiary’s creditors under federal bankruptcy law. In Clark v. Rameker, 573 U.S. 122 (2014), the U.S. Supreme Court ruled unanimously that Inherited IRAs are not “retirement funds” within the meaning of 11 U.S.C. §522(b)(3)(C) and are therefore reachable in bankruptcy.

The consequence is serious. A beneficiary who files Chapter 7 may lose the entire Inherited IRA to creditors, including all post-death growth. A real example is Ruth Heffron’s daughter Heidi, whose $450,000 Inherited IRA was the exact account at issue in Clark; the bankruptcy trustee seized the account after Heidi filed Chapter 7.

Some states — including Florida, Texas, Ohio, and Arizona — have passed statutes that exempt Inherited IRAs from state creditor claims. A common misconception is that these state protections also apply in federal bankruptcy; they sometimes do, if the beneficiary files in a state that allows opt-out under 11 U.S.C. §522(b)(2).

Common Mistakes That Kill Inherited IRA Growth

Beneficiaries lose real money every year by mishandling these accounts. Here are the biggest traps.

  • Taking a lump-sum distribution in year one — This destroys 9 years of compounding and usually triggers the top federal bracket, costing tens of thousands in avoidable tax.
  • Rolling an Inherited IRA into your own IRA (non-spouse) — This is a prohibited rollover under IRC §408(d)(3)(C); the entire balance becomes immediately taxable.
  • Missing the October 31 trust documentation deadline — If a trust is the beneficiary, failure to deliver trust documents to the custodian by October 31 of the year after death disqualifies the trust from see-through status.
  • Ignoring annual RMDs post-2024 — The IRS waiver ended; a missed 2025 RMD triggers the 25% excise tax on the shortfall.
  • Mistitling the account — Any retitling that removes “deceased” or “FBO” language can be deemed a full taxable distribution by the custodian.
  • Forgetting the five-year Roth clock — If the original Roth was open less than five years, earnings withdrawn are taxable under IRC §408A(d)(2)(B).
  • Naming the estate as beneficiary — The estate is a non-designated beneficiary, collapsing the growth window to five years and often forcing probate.
  • Failing to split multiple beneficiaries by December 31 — If heirs don’t create separate Inherited IRAs by December 31 of the year after death, all must use the oldest beneficiary’s life expectancy.
  • Overlooking state income tax withholding — Some states like Kansas and Maine require mandatory withholding that reduces reinvestable growth.
  • Disclaiming without a qualified disclaimer — A disclaimer that fails the nine-month rule under IRC §2518 is treated as a taxable gift.

Do’s and Don’ts for Maximum Growth

Do’s

  • Do retitle the account correctly with “deceased” and “FBO” language because custodians can freeze mistitled accounts.
  • Do project your 10-year tax burden early because spreading withdrawals almost always beats a year-10 lump sum.
  • Do split the IRA by December 31 of the year after death because each beneficiary then gets their own clock.
  • Do consider Roth conversions of your own money during low-income years because Inherited Traditional IRA withdrawals will inflate your AGI.
  • Do coordinate with a CPA or CFP® because the interaction of federal, state, and beneficiary class rules is genuinely complex.

Don’ts

  • Don’t cash out in year one because you forfeit nine years of compounding and often pay the top marginal rate.
  • Don’t name minor grandchildren directly because a UTMA account or trust is almost always better for control and protection.
  • Don’t rely on outdated “stretch IRA” advice because the stretch is gone for most non-spouse beneficiaries after 2019.
  • Don’t forget the October 31 trust documentation deadline because missing it disqualifies see-through treatment.
  • Don’t commingle inherited assets with your own IRA because the commingled amount becomes fully taxable.

Pros and Cons of Holding an Inherited IRA

Pros

  • Continued tax-deferred or tax-free growth because the account retains its IRA tax character.
  • No 10% early-withdrawal penalty at any age because IRC §72(t)(2)(A)(ii) waives the penalty for beneficiaries.
  • Flexibility to time withdrawals within the 10-year window because beneficiaries can match distributions to low-income years.
  • Possible eligible designated beneficiary stretch because EDBs can extend growth over decades.
  • Roth Inherited IRA tax-free compounding because qualified distributions escape federal income tax entirely.

Cons

  • Compressed 10-year window for most heirs because SECURE Act ended the lifetime stretch.
  • No creditor protection in bankruptcy because of Clark v. Rameker.
  • Ordinary income tax on every Traditional distribution because capital gains rates do not apply.
  • Annual RMDs now required if the decedent died after RBD, reducing flexibility.
  • No new contributions allowed because the account is frozen to decedent-sourced assets only.

The Process: Claiming and Maintaining the Account

Step one is to notify the custodian of the death and provide a certified death certificate. The custodian opens a new Inherited IRA account titled in the proper FBO format. The consequence of delay is that the custodian may freeze trading until proper documentation is on file.

Step two is to decide on the distribution method before the first RMD deadline. For most non-spouse beneficiaries, the first RMD (if required) is due December 31 of the year after the year of death, per IRS Publication 590-B. Missing this deadline starts the 25% excise tax clock.

Step three is to submit IRS Form 5329 if any RMD is missed. Filing Form 5329 with a reasonable-cause statement can secure a waiver of the excise tax. A common misconception is that the waiver is automatic — it is not; the IRS must approve the request in writing.

FAQs

Does an Inherited IRA keep earning interest and dividends after the owner dies?

Yes. Investments inside the account continue to earn interest, dividends, and capital gains. The custodian retitles the account and keeps it invested under the new beneficiary’s direction until distributions occur.

Do I have to take all the money out of an Inherited IRA immediately?

No. Most beneficiaries have 10 years to empty the account under the SECURE Act, and Eligible Designated Beneficiaries can stretch distributions over their own life expectancy for much longer growth.

Can I contribute new money to an Inherited IRA to boost growth?

No. Only the decedent’s original assets plus earnings can remain in the account. New contributions are excess contributions subject to a 6% annual penalty under IRC §4973.

Does a Roth Inherited IRA grow tax-free forever?

No. It grows tax-free, but non-spouse beneficiaries must still empty the account within 10 years under the 2024 Final Regulations, even though withdrawals are federally tax-free.

Can I roll an Inherited IRA into my own IRA?

No, unless you are the surviving spouse. A non-spouse rollover is a prohibited transaction that makes the entire balance immediately taxable as ordinary income.

Do I owe the 10% early withdrawal penalty if I’m under 59½?

No. IRC §72(t)(2)(A)(ii) waives the 10% early-withdrawal penalty for all beneficiary distributions, regardless of the beneficiary’s age at the time of withdrawal.

Are Inherited IRAs protected from my creditors in bankruptcy?

No, under federal law per Clark v. Rameker, 573 U.S. 122 (2014). Some states, including Florida and Texas, protect Inherited IRAs from state-law creditor claims by statute.

Do I have to take annual RMDs during the 10-year window?

Yes, if the decedent died after their required beginning date. The 2024 Final Regulations require annual RMDs in years 1–9 plus full distribution by December 31 of year 10.

Can multiple beneficiaries split one Inherited IRA for better growth?

Yes. If heirs create separate Inherited IRAs by December 31 of the year after death, each beneficiary uses their own clock and life expectancy for RMD and growth purposes.

Does the state where I live affect how much of the growth I keep?

Yes. States like Pennsylvania and Illinois exempt qualifying retirement distributions, while California and New Jersey fully tax them as ordinary income on top of federal tax.

Can a trust be the beneficiary without killing the growth window?

Yes, if it qualifies as a “see-through” trust under Treas. Reg. §1.401(a)(9)-4 by meeting the four requirements and delivering trust documents to the custodian by October 31 of the year after death.

Does the five-year rule still exist after SECURE Act?

Yes. The five-year rule still applies when the beneficiary is a non-designated beneficiary such as an estate, charity, or non-qualifying trust, and the decedent died before reaching their required beginning date.
