Inherited IRA Complete Guide

An honest framework for the decisions at hand. Not tax or investment advice — your specifics matter.

The SECURE Act 10-year rule basics

• For deaths after December 31, 2019: most non-spouse beneficiaries must deplete inherited IRA within 10 years of the original owner's death.¹
• Eligible Designated Beneficiaries (EDBs) preserve the stretch option: (1) surviving spouse, (2) minor child of decedent until age of majority (then switches to 10-year), (3) disabled individual, (4) chronically ill individual, (5) beneficiary not more than 10 years younger than decedent.¹
• 2024 IRS final regulations (T.D. 10001): non-EDBs whose decedent had already started Required Minimum Distributions (was past their Required Beginning Date) must take annual RMDs in years 1-9 AND fully deplete by year 10. If decedent died before RBD, no annual RMDs — just full depletion by year 10.²
• RMD penalty relief is over. The IRS waived the 25% excise tax for missed annual RMDs during 2021-2024 while the rules were finalized.³ Starting 2025, missed RMDs trigger the 25% excise tax (10% if corrected within 2 years).

Spousal rollover vs inherited IRA

• Spousal rollover: only available to a surviving spouse. Roll to your own IRA. Uses your own age for RMDs. Most common choice.⁴
• Inherited IRA (spouse as EDB): keep separate. Spouses as EDB are exempt from the 10-year rule and can stretch RMDs over their own life expectancy. Critically: distributions from an inherited IRA are exempt from the 10% early-withdrawal penalty at any age under IRC § 72(t)(2)(A)(ii).⁵
• If spouse is under 59½ and needs access: stay with inherited IRA temporarily (penalty-free), then roll to own when past 59½.
• If significant wealth difference: spousal rollover may push you into higher future RMDs once you hit your own RBD (age 73-75 depending on birth year under SECURE 2.0).⁶

Withdrawal strategy within the 10-year window

• Default 'equal 10-year payments': simple but suboptimal for most.
• Front-loaded: take larger withdrawals in low-income years, smaller in high-income years.
• Back-loaded: defer into year 10 — works only if future brackets likely to be lower (semi-retirement, gap year).
• The biggest mistake: doing nothing and taking a lump sum in year 10 — often the highest-tax outcome.

Roth conversions during the inherited-IRA window

• You cannot Roth-convert a non-spouse inherited IRA. Only the original owner's surviving spouse (who treats the IRA as their own) can execute a Roth conversion from formerly-inherited funds.⁷
• The coordinated play: annual withdrawals from inherited IRA pay your tax bill + Roth conversions from your own traditional IRA move future growth into tax-free territory.
• Particularly powerful if inherited IRA is large relative to your own retirement assets, and you still have low-bracket years before Social Security/RMDs arrive.

Inherited Roth IRA — different rules

• Still subject to 10-year depletion rule for non-spouse beneficiaries.¹
• BUT: qualified distributions are tax-free (Roth treatment preserved).
• Strategy: let it compound tax-free the full 10 years, withdraw lump in year 10. Maximum tax-free growth.
• 5-year rule exception: if you inherit a Roth IRA that's less than 5 years old (measured from original owner's first Roth contribution), earnings portion is taxable until the 5-year clock is met. Usually not an issue for mature Roths.⁸
• Annual RMDs during the 10-year window are NOT required for inherited Roth (because original Roth owners had no RMDs) — only the year-10 depletion.

Trust beneficiaries

• Complex rules depending on trust type. Look-through trusts (conduit vs accumulation) have different treatment.
• Conduit: trust must distribute everything out; beneficiary tax rates apply. Simpler for 10-year rule.
• Accumulation: trust can retain funds; highly compressed trust tax brackets apply. Often disadvantageous.
• Specialist attorney + advisor review essential — trust-beneficiary inherited IRAs are easy to mishandle.
