SECURE Act 2.0 in Practice: How Inherited Retirement Account Rules Play Out in Real Estates

The SECURE Act (2019) and SECURE Act 2.0 (2022) fundamentally rewired inherited retirement accounts. The "stretch IRA," which allowed beneficiaries to take distributions over their lifetime, is largely gone. In its place: a 10-year mandatory distribution window for most beneficiaries. But "10 years" is deceptively simple. The actual rules depend on who the beneficiary is, what type of account they inherited, how the account is titled, and whether a trust sits between the beneficiary and the money. Each variable creates different tax and compliance consequences.

This guide walks through the core beneficiary categories, works through four real-world scenarios that expose common failures, and explains the coordination nightmare between estate attorneys, CPAs, and financial advisors.

The Three Categories of Inherited Account Beneficiaries

The SECURE Act created a new classification system. Not all beneficiaries are treated the same.

Eligible Designated Beneficiaries (EDBs)

A handful of beneficiary types still get the old "stretch" treatment. These are called Eligible Designated Beneficiaries.

EDBs include:

• The surviving spouse of the decedent.
• A child of the decedent who has not yet reached majority age (usually 18, or 26 if still in school).
• A parent of the decedent (if the decedent was a minor or dependent).
• A beneficiary who is chronically ill or permanently and totally disabled (as defined by IRS standards).
• A beneficiary who is not more than 10 years younger than the person who died.

For EDBs, the stretch remains. They calculate annual Required Minimum Distributions (RMDs) using their own life expectancy. No 10-year deadline. They can defer distributions across decades.

Critical note: EDB status must be affirmatively established. An account must pass through the beneficiary classification step at the account holder's death. If the beneficiary designation form doesn't clearly state who qualifies as an EDB, or if a trust is named as beneficiary, the account may not recognize the EDB's eligibility. Many inherited accounts have been wrongly classified as non-designated beneficiary accounts because the custodian didn't receive proper documentation.

Non-Spouse Designated Beneficiaries (Non-EDBs)

An adult child, a sibling, a friend, or any non-spouse who doesn't meet the EDB criteria falls here. This is the 10-year rule category.

Rules for non-spouse designated beneficiaries:

• The beneficiary must drain the entire account balance by December 31 of the tenth year following the year of the account holder's death.
• There are NO annual RMDs during years 1 through 9. The beneficiary can take nothing or everything. That's their choice.
• But by year 10, the account must be zero.
• Any distribution taxes as ordinary income, and if the beneficiary is in a high tax bracket and takes a large lump sum, the tax hit is immediate and substantial.

This category is where the most expensive mistakes happen.

Non-Designated Beneficiaries

If the beneficiary designation names an entity that is not a person (for example, the estate, a charity, or a trust that does not "look through" to individual beneficiaries), the account becomes a non-designated beneficiary account. The 5-year rule applies: the entire account must be emptied by December 31 of the fifth year following the death. After that, there's no tax deferral at all.

This is the worst outcome for tax purposes. Non-designated beneficiary accounts are rare if beneficiary designations are done correctly, but they happen when someone names their estate or a poorly drafted trust.

Real Scenario 1: The Adult Child Who Did Nothing for 9 Years

The setup is common. Susan dies on March 15, 2023. Her IRA custodian (Fidelity) shows a balance of $450,000. Her adult son Marcus is named as the sole designated beneficiary. Marcus is 38 years old. He does not qualify as an EDB. He's a non-spouse designated beneficiary.

The custodian sends Marcus a beneficiary notification letter. It says something like: "Your inherited IRA must be distributed by December 31, 2032." Marcus puts the letter in a drawer.

For years 1 through 9 (2023 through 2031), Marcus takes no distributions. He doesn't need the money. His own retirement accounts are solid. The inherited IRA sits there, and because Marcus isn't taking it out, it's still growing. By the end of 2031, year 9, the balance has grown to $495,000.

Then, in September 2032, Marcus's financial advisor finally reviews the account. She realizes there are only three months left. The custodian must send Marcus a 1099-R for the entire $495,000 in December 2032, reported as income on his 2032 tax return.

Marcus, who earns $120,000 a year, suddenly has $615,000 of total taxable income. His effective tax rate on the inherited IRA, combined with his earned income, lands him in the 32% federal bracket (plus 3.8% net investment income tax for high earners, plus state tax in most states). He owes roughly $158,000 in federal and state taxes on the inherited IRA.

That's one-third of the account gone, because Marcus did nothing for nine years and then couldn't avoid a year-10 lump sum.

If Marcus had taken $45,000 per year for ten years (2023 through 2032), he would owe roughly $11,000 per year in taxes, totaling $110,000 across a decade. That's $48,000 less in total taxes. The difference is bracket creep and the tax code's rate structure. Small, regular distributions spread the tax across multiple years and lower brackets.

Malpractice exposure: If an estate attorney or financial planner knows Marcus inherited the account and fails to document the 10-year deadline in writing to the beneficiary, that professional may face a claim if Marcus bundles everything into year 10 and gets hit with a massive tax bill. Documentation is not optional.

Real Scenario 2: The Surviving Spouse (Eligible Designated Beneficiary)

The setup: Tom dies on June 1, 2023. His IRA is worth $280,000. His surviving spouse, Linda, is the named beneficiary.

Linda is an EDB. She gets the stretch. She can calculate her own RMD based on her age and life expectancy. If Linda is 65 at Tom's death, she uses IRS Table II (Uniform Lifetime Table) to calculate her annual RMD. At age 65, the distribution period is 21.8 years. Her RMD in the first year is $280,000 / 21.8 = approximately $12,800. Each subsequent year, her balance goes down, and so does her RMD, unless the account grows.

But there's a catch: Linda has an election to make.

Linda can either:

1. Keep the account in Tom's name as an inherited IRA and take RMDs as the beneficiary.
2. Treat the IRA as her own (spousal rollover) and delay RMDs until her own Required Beginning Date, which is April 1 of the year after she turns 73 (under current rules).

If Linda is in her mid-60s and still working, or if she doesn't need the money yet, rolling over the account to her own IRA can save her years of RMDs. If she takes the rollover, the account is no longer "inherited." It becomes her IRA. She delays RMDs until age 73 or later, and the account title changes from "IRA FBO Tom, deceased 6/1/23 (Linda, beneficiary)" to "Linda's IRA."

Execution problem: Many financial institutions don't proactively offer the spousal rollover option. The notification letter might not mention it. The custodian might not have the form readily available. If Linda doesn't know the election exists, she may remain in inherited account status indefinitely, triggering annual RMDs when a rollover would have been more tax-efficient.

Documentation: The estate attorney should include a checklist in the final accounting memo that reminds the executor or spouse of the spousal rollover decision. The CPA should communicate the tax implications. Linda should receive written notice in plain English of what she's eligible for.

Real Scenario 3: The Disabled Dependent Child (Eligible Designated Beneficiary)

The setup: Robert dies on October 12, 2023. He has a 42-year-old son, David, who has been diagnosed with Down syndrome and receives Supplemental Security Income (SSI) and Medicaid benefits. Robert's IRA balance is $320,000. Robert named David directly as the beneficiary of the account.

David is an EDB. He is permanently and totally disabled. He gets the stretch under SECURE Act rules.

But David is also on SSI and Medicaid. Both programs have strict resource limits. SSI limits resources to $2,000 (for individuals) or $3,000 (for couples). Medicaid limits vary by state but are often around $2,000 to $6,000. Any inherited account owned in David's name, even an inherited IRA, counts as a resource to SSI and Medicaid.

Here's the trap: If David inherits the $320,000 IRA in his own name, he immediately exceeds the SSI and Medicaid resource limits by several hundred thousand dollars. His benefits could be terminated or suspended.

The solution is a Special Needs Trust (SNT), also called a Supplemental Needs Trust. Robert should not have named David directly as the beneficiary. Instead, Robert should have named the SNT as the beneficiary of the IRA.

When the SNT is the beneficiary, the SNT custodian (trustee) can take RMDs based on David's EDB status (David's life expectancy), but the trustee has discretion over distributions to David. The trustee can accumulate income and principal in the trust and use trust assets to pay for items that improve David's quality of life (therapy, equipment, education, entertainment) without triggering SSI or Medicaid disqualification. The trust is a separate legal entity, and the resource rules apply to the trust, not directly to David.

But the SECURE Act complicates this. If a trust is the beneficiary of the inherited account, the IRS must be able to "look through" to the individual beneficiary(ies) of the trust and confirm that the individual is an EDB. The look-through rules require specific trust language: The trust document must provide that trust income is distributable to (or held for the benefit of) an EDB, and the trustee must provide a copy of the trust document to the account custodian.

Many SNTs drafted before the SECURE Act, or drafted by estate planners unfamiliar with post-SECURE Act requirements, fail the look-through test. The result: the account is classified as a non-designated beneficiary account (because the custodian can't confirm an EDB behind the trust), and the 5-year rule applies instead of the stretch.

Professional coordination failure: The estate attorney drafts the SNT. The financial advisor doesn't review the trust language against SECURE Act look-through requirements. The IRA custodian receives a copy of the trust, sees that it doesn't include required language, and treats it as non-designated. By the time anyone notices, a year has passed, and the accounts are classified wrong.

The fix: At David's death planning stage, the estate attorney must ensure the SNT is SECURE Act-compliant. If an existing SNT is not, it must be amended. The custodian must receive explicit documentation that David is an EDB with look-through language in the trust.

Annual RMD calculation for David would be based on his age and life expectancy, not the trust's. The trustee takes the annual RMD, and the remaining balance stays in the trust, protected from SSI/Medicaid resource limitations.

Real Scenario 4: The Conduit Trust vs. Accumulation Trust Disaster

Here's where trust structure and the SECURE Act collide hard.

Patricia died in 2019, before the full SECURE Act rules took effect. Her trust named her daughter Emma as a beneficiary of an inherited 401(k) worth $550,000. Patricia's trust was a "conduit trust."

A conduit trust is a trust that is required (by its language) to distribute all current trust income to beneficiaries annually. It functions as a pass-through. Income comes out of the 401(k), flows through the trust, and goes to Emma. This was the classic trust structure for inherited accounts before SECURE Act 2.0, because the stretch was available to trusts, and annual distributions kept trust tax rates lower.

Under pre-SECURE rules, conduit trusts were ideal. The 401(k) stayed in the trust (or was rolled over to an inherited IRA in the trust's name), and Emma got distributions based on her life expectancy, decade after decade.

But SECURE Act 2.0 changed the rules for trusts. If a trust is the beneficiary of an inherited retirement account, the trust itself must satisfy the EDB criteria, or the 10-year rule applies to the entire account, and RMDs are waived.

Patricia's conduit trust was not an EDB trust. Emma was the beneficiary, but the trust itself didn't qualify. Result: the account gets the 10-year rule. The $550,000 must be distributed by December 31, 2029 (ten years after Patricia's death in 2019).

Here's the tax disaster: A conduit trust distributes all current income to beneficiaries. But under SECURE Act 10-year rules, the trustee can choose the distribution schedule. If the trustee (Patricia's brother, serving as executor) decides to take the entire $550,000 out in year 5, what happens?

The 401(k) distributes $550,000 to the trust. The trust receives it and must distribute it to Emma under conduit language. Emma gets the $550,000, and the 401(k) is done.

But for the years when the trust was holding the inherited 401(k) and receiving distributions of principal (not just income), the trust was accumulating taxable income that wasn't being paid out. The trust, as a separate entity, got hit with income tax on any net income the account generated. Trust tax rates are extremely compressed. A trust reaches the highest federal income tax bracket (37%) at around $14,000 of taxable income (as of 2024). So the trust was paying 37% federal tax on income that would have been taxed at Emma's (probably lower) rate if she owned the account directly.

This is the "acceleration of income at trust rates" problem. The SECURE Act 10-year rule interacts badly with conduit trust language, forcing income through the trust and exposing it to compressed tax rates.

If Patricia's estate attorney had instead drafted an "accumulation trust," which allows the trustee to accumulate income in the trust or distribute it (at trustee discretion), the outcome would have been different. An accumulation trust gives the trustee flexibility. But accumulation trusts still face the 37% tax rate issue if income is retained.

The real solution: New inherited account trusts should be designed as non-conduit, accumulation trusts, with language that gives the trustee express authority to distribute to beneficiaries using a Conduit Exception Trust (CET) or Dynasty Trust structure that minimizes income tax acceleration. But this requires both the estate attorney and the financial advisor to understand SECURE Act 2.0 implications before the account ever enters the trust.

Many trusts drafted before 2023 are now classified wrongly under SECURE Act rules. They're creating tax problems for families and exposing professionals to malpractice claims.

The Inherited Roth IRA Exception

Inherited Roth IRAs have one key advantage: distributions are tax-free. But the SECURE Act 10-year rule still applies to Roth IRAs. The beneficiary must empty the account by year 10.

The tax-free part is the win. If Marcus (from Scenario 1) had inherited a $450,000 Roth IRA instead of a traditional IRA, taking it all out in year 10 would be tax-free. He'd owe zero federal income tax on the $450,000. That's a massive difference.

But there's a wrinkle with inherited Roths: the pro-rata rule doesn't apply.

If someone owns both a traditional IRA and a Roth IRA and does a Roth conversion, the IRS applies a pro-rata rule. They calculate the percentage of traditional vs. Roth across all the person's IRAs, and that percentage applies to the conversion. You can't cherry-pick converting only the after-tax basis.

With inherited Roths, there is no pro-rata rule. Each inherited Roth is treated separately. A beneficiary can inherit a Roth from one person and a traditional IRA from another person, and they don't offset.

Also, inherited Roth IRAs don't have Required Minimum Distributions during the life of the original account owner. Only designated beneficiaries take RMDs. This means if someone funds a Roth at age 70 and never touches it, the Roth owner pays no RMDs during their lifetime. Only the beneficiary deals with RMDs (or the 10-year rule).

For the beneficiary, inherited Roth IRAs allow the same 10-year distribution window as traditional inherited IRAs, but with zero tax. If the beneficiary has funds elsewhere to live on, they can leave the Roth untouched for nine years and then take distributions in year 10, all tax-free. That's useful flexibility for beneficiaries in high-income years or those who want to manage their tax brackets.

The Coordination Challenge: Estate Attorney, CPA, and Financial Advisor

The SECURE Act inherited account rules are not one person's job. They require coordination.

The estate attorney must know the inherited account rules well enough to draft beneficiary designations correctly, recommend SNT structures for disabled beneficiaries, and ensure trust documents include look-through language if trusts are named as beneficiaries.

The CPA must review the inherited account classification immediately after the death, confirm the account is titled correctly, understand what distributions can be taken, and plan the annual RMD strategy to minimize tax across the 10-year (or stretch) window.

The financial advisor must track the calendar, ensure distributions happen on time, confirm that year 10 is being executed (not forgotten like Scenario 1), and alert the other professionals if problems arise.

In practice, these three often don't talk. The attorney files the estate, the CPA does the return, and the financial advisor manages the account. Each assumes the others have handled their part. No one owns the end-to-end timeline.

This is how inherited accounts get misclassified, why conduit trusts accidentally trigger 37% trust tax rates, and why beneficiaries miss 10-year deadlines.

The solution is a simple checklist and a documented distribution plan. Here's what should happen:

1. Within 60 days of death, the attorney should contact the CPA and financial advisor. Share the beneficiary designation documents and account custodian contact information.

2. The financial advisor should obtain a current statement and confirm the account is titled correctly (inherited vs. regular vs. conduit trust, etc.).

3. The CPA should determine the beneficiary classification (EDB, non-EDB, non-designated) and calculate the first-year RMD (if applicable).

4. All three should collaborate on a written distribution plan. This plan should specify the annual distribution amount (if required), any tax elections (like spousal rollover), and the responsible parties. It should be shared with the beneficiary in writing.

5. The attorney should include the distribution plan in the final estate accounting memo. This protects the attorney and alerts the beneficiary.

6. The financial advisor should set an annual reminder in their calendar. Each December, they should confirm that year-end distributions have been taken and that the next year's RMD (if required) is calculated correctly.

7. In year 9 of a non-EDB account, all three should issue an explicit warning to the beneficiary. Year 10 is the final year. The beneficiary must understand the consequences.

Without this coordination, the inherited account rules become a trap.

FAQ

Q: Can a beneficiary take only part of an inherited IRA in the 10-year window and leave the rest?

A: No. Under SECURE Act rules for non-designated beneficiaries, the entire account must be emptied by December 31 of year 10. There's no exception for partial distributions. However, for Eligible Designated Beneficiaries, annual RMDs are required, and the account can span their lifetime, so the 10-year deadline doesn't apply to them.

Q: If my spouse inherits my IRA, can they delay distributions indefinitely?

A: Yes, if they elect a spousal rollover. A surviving spouse who rolls over an inherited IRA to their own IRA delays Required Minimum Distributions until April 1 of the year after they turn 73 (under current law). That can be a deferral of many years. However, the spouse must make this election affirmatively. If they don't, they're treated as a non-spouse designated beneficiary and face the 10-year rule.

Q: What happens if a beneficiary dies before the 10-year deadline is met?

A: The successor beneficiary steps in. If the original beneficiary dies in year 5 with five years left, the successor beneficiary has the remaining five years to empty the account. The clock doesn't reset. This is why beneficiary designations on inherited accounts are critical. If the original inherited account doesn't have a named successor beneficiary, the account may revert to the deceased beneficiary's estate, triggering non-designated beneficiary status and the 5-year rule.

Q: If an inherited IRA sits in a bank, earning almost no interest, do the 10-year RMD rules still apply?

A: Yes. The distribution requirement is based on the calendar clock, not account activity. Even if the account earns $10, the entire balance must be distributed by year 10 (for non-designated beneficiaries). The rate of return doesn't affect the deadline.
