What Is the Inherited IRA 10-Year Rule Under SECURE 2.0?

The SECURE Act, originally signed in 2019, eliminated the “stretch IRA” strategy for most beneficiaries. Previously, non-spouse beneficiaries could stretch distributions over their entire life expectancy. This allowed decades of tax-deferred growth. The SECURE 2.0 Act, enacted in 2022, made further modifications that impact 2026 planning.

For 2026, the inherited IRA 10-year rule applies to most designated beneficiaries who inherit traditional IRAs, Roth IRAs, 401(k)s, and other qualified retirement accounts. The rule requires complete distribution within 10 calendar years. However, the distribution schedule within that period depends on critical factors.

Three Categories of Beneficiaries

Understanding beneficiary classification is fundamental to advising clients on the inherited IRA 10-year rule. The IRS recognizes three distinct categories:

• Eligible Designated Beneficiaries (EDBs): Surviving spouses, minor children, disabled individuals, chronically ill individuals, and beneficiaries no more than 10 years younger than the deceased account owner may use life-expectancy payout rules.
• Non-Eligible Designated Beneficiaries: Adult children and most other individual beneficiaries face the standard 10-year rule.
• Non-Designated Beneficiaries: Estates, charities, and certain trusts follow different distribution schedules based on the owner’s required beginning date.

Impact on Tax Planning Engagements

For CPAs building advisory practices, the inherited IRA 10-year rule creates substantial planning opportunities. Clients need guidance on distribution timing to minimize tax impact. A beneficiary in a high-income year may want to delay distributions. Conversely, lower-income years present opportunities to accelerate distributions at favorable rates.

Who Qualifies as an Eligible Designated Beneficiary?

Eligible designated beneficiary (EDB) status is the most valuable classification for inherited IRA planning. EDBs can stretch distributions over life expectancy rather than facing the compressed 10-year timeline. For 2026, understanding EDB qualification criteria is essential for CPAs serving high-net-worth clients with substantial retirement assets.

Surviving Spouse Beneficiaries

Surviving spouses receive the most favorable treatment. They can roll inherited IRAs into their own accounts, treat the account as their own, or take life-expectancy distributions as a beneficiary. This flexibility allows strategic planning based on age differences and income needs.

Minor Children of the Account Owner

Minor children qualify as EDBs only until reaching the age of majority. Once the child reaches age 18 (or 21 in some states), the 10-year rule clock begins. This transition point requires careful planning to avoid unexpected tax acceleration.

Disabled and Chronically Ill Beneficiaries

The chronically ill pathway to EDB status represents a significant planning opportunity often overlooked by tax professionals. Under IRC §7702B(c)(2), an individual qualifies as chronically ill if a licensed healthcare practitioner certifies they meet specific criteria within the preceding 12 months.

Importantly, chronically ill status does not require Social Security disability approval. A beneficiary earning $100,000 annually may still qualify if they require substantial supervision due to cognitive impairment. This applies to many individuals on the autism spectrum or with other conditions affecting independent living.

EDB Category	Qualification Requirements	Distribution Option
Surviving Spouse	Legally married to decedent	Rollover, own account, or life expectancy
Minor Child	Under age of majority (18-21)	Life expectancy until majority, then 10-year rule
Disabled	SSA disability determination	Life expectancy stretch
Chronically Ill	Healthcare practitioner certification under IRC §7702B(c)(2)	Life expectancy stretch
Within 10 Years	Not more than 10 years younger than decedent	Life expectancy stretch

How Does the Required Beginning Date Impact Distribution Requirements?

The required beginning date (RBD) is the critical pivot point that determines distribution requirements for non-EDB beneficiaries. For 2026, understanding RBD timing is essential for accurate client guidance on the inherited IRA 10-year rule.

Current RBD Rules for 2026

SECURE 2.0 changed the RMD starting age. For 2026, most account owners must begin taking RMDs at age 73. For younger individuals who will reach age 74 after 2032, the RMD age increases to 75. This creates planning complexity when advising clients on pre-death IRA strategies.

Death Before Required Beginning Date

When the account owner dies before reaching their RBD, non-EDB beneficiaries face the 10-year rule without annual RMD requirements during years 1-9. The entire account must be distributed by December 31 of the 10th year following death. This provides maximum flexibility for tax planning across the decade.

CPAs can help clients optimize by analyzing projected income across the 10-year window. Distributions can be front-loaded in low-income years, back-loaded to maximize deferral, or spread evenly based on cash flow needs.

Death On or After Required Beginning Date

The rules change dramatically when the owner dies on or after their RBD. Non-EDB beneficiaries must take annual RMDs during years 1 through 9, calculated using the beneficiary’s life expectancy or the decedent’s remaining life expectancy (whichever is longer). The remaining balance must be distributed by December 31 of year 10.

This creates less planning flexibility. However, it also creates advisory opportunities. Use our inherited IRA calculator to model annual RMD requirements and project the 10-year tax impact for clients facing this scenario.

Year-of-Death RMD Considerations

One commonly missed requirement is the year-of-death RMD. If the account owner died after their RBD but before taking the full RMD for the year of death, the beneficiary must satisfy this distribution. This is separate from the beneficiary’s own distribution obligations.

What Are the 2026 RMD Penalty Provisions Under SECURE 2.0?

SECURE 2.0 significantly reduced the excise tax penalty for missed RMDs. Previously, beneficiaries faced a punishing 50% penalty on any RMD shortfall. The 2026 penalty structure provides more favorable treatment while still encouraging compliance.

Current Penalty Structure

The default excise tax for a missed RMD in 2026 is 25% of the amount that should have been distributed but was not. However, if the beneficiary corrects the shortfall promptly, the penalty reduces to 10%. The penalty applies to the shortfall amount, not the entire account balance.

Importantly, the excise tax is in addition to ordinary income tax owed on the eventual distribution. This creates a dual tax burden that CPAs must help clients avoid through proper planning and monitoring.

IRS Penalty Relief for 2020-2023 Inherited IRAs

The IRS provided penalty relief for certain beneficiaries who inherited accounts between 2020 and 2023. During this transition period, the rules regarding annual RMDs for 10-year rule beneficiaries were unclear. Many beneficiaries did not take annual RMDs during years 1-9.

The IRS relief means these beneficiaries may not owe excise tax for missed annual RMDs during the relief period. However, the accounts must still be emptied by the applicable 10-year deadline. Any remaining balance after December 31 of the 10th year is subject to excess-accumulation excise tax rules.

Penalty Scenario	2026 Excise Tax Rate	Correction Opportunity
Missed annual RMD (default)	25% of shortfall	Reduced to 10% if timely corrected
Failed to empty by year 10	25% of remaining balance	Limited correction window
2020-2023 inheritance (relief period)	0% for missed annual RMDs years 1-9	Must still empty by year 10

How Do Inherited Roth IRAs Differ from Traditional IRAs?

 

 

While inherited Roth IRAs are subject to the same post-death distribution rules as traditional IRAs, the tax treatment creates fundamentally different planning opportunities. For CPAs advising business owners and high-net-worth clients, understanding these distinctions is critical.

Tax-Free Distribution Advantage

Most qualified Roth IRA distributions are completely income-tax-free to the beneficiary. This includes all earnings if the original account owner satisfied the five-year rule. This creates a significant wealth transfer advantage compared to traditional IRAs, where every dollar is taxed as ordinary income.

However, the inherited IRA 10-year rule still applies. Non-EDB beneficiaries must empty inherited Roth IRAs within 10 years. The strategic difference is that beneficiaries should maximize deferral since distributions are tax-free. Delaying until year 10 maximizes tax-free growth.

SECURE 2.0 Changes to Employer Roth Accounts

SECURE 2.0 eliminated lifetime RMDs from designated Roth accounts in employer plans beginning in 2024. Account owners no longer must take RMDs from Roth 401(k)s or Roth 403(b)s during their lifetime. This makes employer Roth accounts more attractive for wealth transfer planning.

However, inherited Roth accounts from employer plans remain subject to post-death distribution rules. Beneficiaries still face the 10-year rule or annual RMD requirements based on the owner’s RBD status.

What Planning Strategies Should CPAs Recommend to Clients?

The inherited IRA 10-year rule creates opportunities for CPAs to deliver high-value tax strategy services. These planning engagements can command premium fees while generating significant client savings.

Pre-Death Roth Conversion Strategies

For clients with substantial traditional IRA balances, systematic Roth conversions before death can dramatically reduce the tax burden on beneficiaries. Converting during the window between retirement and RMDs (typically age 62-73) allows clients to fill lower tax brackets.

For 2026, a married couple filing jointly can access the 12% bracket up to $96,950 of taxable income after their $32,200 standard deduction. Strategic conversions of $60,000-$80,000 annually during this window can convert hundreds of thousands at favorable rates.

Special Needs Trust Planning

For families with disabled or chronically ill children, naming a properly drafted special needs trust as beneficiary can preserve both EDB status and government benefit eligibility. This strategy requires coordination with estate planning attorneys but can save over $1 million in taxes on a $500,000 inherited IRA.

Multi-Year Distribution Modeling

CPAs should model distribution scenarios across the full 10-year window for beneficiaries. Consider projected income, tax bracket changes, state residency changes, and other deductions. The optimal distribution schedule may involve:

• Front-loading distributions during low-income years (sabbaticals, between jobs, early retirement)
• Splitting distributions between spouses when filing jointly to manage bracket creep
• Timing distributions to maximize other tax benefits (education credits, premium tax credits)
• Coordinating with charitable giving strategies for high-income beneficiaries

Qualified Charitable Distribution Alternative

For charitably inclined beneficiaries over age 70½, qualified charitable distributions (QCDs) from inherited IRAs can satisfy RMD requirements while excluding the distribution from taxable income. For 2026, QCDs are limited to $105,000 annually (adjusted for inflation), but can be a powerful tool for beneficiaries who do not need the income.

What Common Mistakes Must CPAs Help Clients Avoid?

The complexity of the inherited IRA 10-year rule creates numerous opportunities for costly errors. CPAs who help clients avoid these mistakes deliver immediate, measurable value.

Transfer Method Errors

Non-spouse beneficiaries cannot roll inherited IRAs into their own accounts. The account must be transferred via trustee-to-trustee transfer into a properly titled inherited IRA. A mistake here can trigger immediate taxation of the entire account balance.

Assuming No Annual RMDs Apply

Many beneficiaries and advisors incorrectly assume the 10-year rule means no distributions are required until year 10. This is only correct if the owner died before their RBD. If death occurred on or after RBD, annual RMDs are mandatory during years 1-9.

Overlooking Chronically Ill EDB Status

Many CPAs default to the SSI/SSDI disability route without exploring the chronically ill pathway. This leaves substantial tax savings on the table for families with beneficiaries who require supervision but do not qualify for Social Security disability benefits.

Uncle Kam in Action: CPA Saves Client $180,000 with EDB Strategy

Client Profile: Sarah, a CPA in Dallas, was advising the Martinez family on a $650,000 inherited traditional IRA. The beneficiary was their 28-year-old son, Miguel, who has high-functioning autism. Miguel works part-time in a supervised setting and lives independently with support.

The Challenge: The family assumed Miguel would face the standard 10-year distribution rule. With Miguel in the 24% federal bracket, forced distributions over 10 years would generate approximately $156,000 in federal tax alone. The family was prepared to accept this outcome.

The Uncle Kam Solution: Sarah recognized that Miguel might qualify as chronically ill under IRC §7702B(c)(2). She coordinated with Miguel’s healthcare providers to obtain certification that he requires substantial supervision due to cognitive impairment. This qualified Miguel as an eligible designated beneficiary.

Using Uncle Kam’s tax planning software, Sarah modeled a life expectancy distribution strategy. Miguel could stretch the inherited IRA over his 55.5-year life expectancy (based on IRS tables). Annual distributions start at approximately $11,700 and increase gradually.

The Results:

• Total Tax Savings: $180,000+ in federal tax over Miguel’s lifetime
• Advisory Fee: $4,500 for planning and implementation
• First-Year ROI: 40x return on investment
• Ongoing Revenue: $1,800 annually for monitoring and annual distribution planning

The Martinez family was thrilled with the outcome. Sarah gained three referrals from the family’s network and established a recurring advisory relationship. By understanding the inherited IRA 10-year rule nuances and exploring all EDB categories, Sarah delivered life-changing value.

Frequently Asked Questions

Can a beneficiary change the distribution schedule after inheritance?

No. The beneficiary classification and distribution requirements are determined at the time of the account owner’s death. The beneficiary’s choices are limited to distribution timing within the applicable rules. However, strategic distribution planning within those constraints can generate significant tax savings.

What happens if a minor child EDB reaches the age of majority?

When a minor child beneficiary reaches the age of majority (18 or 21 depending on state law), the 10-year rule clock begins. The account must be fully distributed by December 31 of the 10th year after reaching majority. This transition requires careful planning to avoid unexpected tax acceleration during the child’s early earning years.

Do inherited Roth 401(k)s follow the same rules as inherited Roth IRAs?

Yes. Inherited Roth accounts from employer plans follow the same distribution rules. The 10-year rule applies to non-EDB beneficiaries. However, qualified distributions remain tax-free. Beneficiaries should consider rolling inherited Roth 401(k)s to inherited Roth IRAs for more investment options and potentially lower fees.

How does the chronically ill certification process work?

A licensed healthcare practitioner must certify that the individual meets one of three tests under IRC §7702B(c)(2) within the preceding 12 months. The most common pathway is certification that the individual requires substantial supervision to protect against health or safety threats due to severe cognitive impairment. No Social Security disability determination is required.

Can trusts qualify as eligible designated beneficiaries?

Trusts themselves are not EDBs. However, a properly drafted “see-through” or “conduit” trust can allow the individual trust beneficiary’s status to determine distribution rules. For disabled or chronically ill beneficiaries, special needs trusts can preserve EDB status while protecting government benefit eligibility. This requires careful drafting by an estate planning attorney experienced in these rules.

What should CPAs do if they discover a client missed annual RMDs in prior years?

Take immediate corrective action. Distribute the missed amount as soon as possible. File IRS Form 5329 to report the shortfall and request penalty waiver for reasonable cause. For 2026, the penalty is 25% of the missed amount (10% if timely corrected). The IRS may waive penalties entirely if reasonable cause is demonstrated, particularly during the 2020-2023 transition period when the rules were unclear.

How do state income taxes affect inherited IRA planning?

State tax treatment varies significantly. Some states do not tax retirement distributions. Others have high rates. If the beneficiary is considering relocation, strategic distribution timing around the move can generate substantial state tax savings. Additionally, some states have separate inheritance or estate tax rules that may apply to larger accounts.

Can beneficiaries disclaim inherited IRAs to achieve better tax outcomes?

Yes. A qualified disclaimer allows a beneficiary to refuse the inheritance within nine months of the account owner’s death. The account then passes to the contingent beneficiary named in the beneficiary designation form. This can be useful if the primary beneficiary is in a high tax bracket and the contingent beneficiary is in a lower bracket or qualifies as an EDB.
