Inherited IRA Rules After SECURE Act 2.0: What Your Family Needs to Know
The 10-year rule. The annual RMD trap. The exceptions. And the strategies that can save your family $50,000+ in unnecessary tax.
If you inherit a retirement account from a parent, the rules that govern what you can do with it are some of the most complex in the entire tax code. They've changed twice in the past five years (SECURE Act in 2019, SECURE 2.0 in 2022), and they catch families off guard with surprise tax bills that could have been avoided with even modest planning.
This explainer covers what happens when you inherit a traditional IRA, Roth IRA, or 401(k) under the rules in effect as of 2024-2026. (Important: rules continue to evolve; always confirm specifics with a tax professional in your state at the time of inheritance.)
The 10-year rule, plainly
For most non-spouse beneficiaries who inherit a retirement account after January 1, 2020, the inherited account must be fully distributed within 10 years of the original owner's death.
That's the headline rule. It replaced the old "stretch IRA" provision that let beneficiaries take distributions over their entire lifetime, smoothing the tax hit over decades. Now: 10 years, and the entire balance must be out.
Why this matters: a $500,000 inherited Traditional IRA used to be tax-smoothed over 30–40 years. Now it has to come out in 10. If your other income is high during those 10 years, the additional distributions can push you into much higher tax brackets. A typical American family might pay $40,000–$80,000 more in cumulative federal income tax than they would have under the old rules.
The annual RMD trap (most beneficiaries miss this)
Here's the part that's most commonly misunderstood: depending on whether the original owner had reached their Required Beginning Date (RBD), you may also have to take annual minimum distributions DURING the 10-year window — not just empty the account by year 10.
Specifically:
- If the original owner had NOT yet reached their RBD (typically age 73 for most retirees, or 75 for those born after 1959), you can wait until year 10 and take it all then if you want.
- If the original owner HAD reached their RBD, you must take an annual RMD each year of the 10-year window, calculated using your life expectancy table — AND empty the account by year 10.
The IRS finalized this interpretation in regulations issued in 2024. Many beneficiaries (and even some tax preparers) missed the annual RMD requirement during the years of confusion. Penalty for missing an RMD: 25% of the amount that should have been distributed (reduced to 10% if corrected promptly).
Action: if you inherited a retirement account in 2020-2024 from someone who had already started taking RMDs, talk to a CPA immediately about whether you owe back RMDs.
The "Eligible Designated Beneficiary" exceptions
Certain beneficiaries are exempt from the 10-year rule and can still use the old stretch-IRA approach. These are called "Eligible Designated Beneficiaries" (EDBs):
- Surviving spouse. Has the most flexibility — can roll the account into their own IRA, treat it as inherited, or take a stretch.
- Minor child of the original owner. Can use the stretch until reaching the age of majority (varies by state, typically 18 or 21), then the 10-year clock starts.
- Disabled beneficiary. Defined by IRS standards; can use the stretch for life.
- Chronically ill beneficiary. Similar to disabled but with different qualification criteria.
- Beneficiary not more than 10 years younger than the original owner. Typically a sibling or close-in-age friend.
If you fit one of these categories, you should specifically claim Eligible Designated Beneficiary status with the IRA custodian. Custodians don't always offer the option proactively — you may need to ask.
Inherited Roth IRA — different math, same 10-year clock
Inherited Roth IRAs are tax-free for the beneficiary (assuming the 5-year holding period was satisfied by the original owner before death). But they're still subject to the 10-year rule.
Strategy: because inherited Roth distributions are tax-free, the optimal play is usually to wait until year 10 and take the full distribution then. This maximizes the time the assets keep growing tax-free.
Unlike inherited Traditional IRAs, inherited Roth IRAs do NOT have an annual RMD requirement during the 10-year window, regardless of the original owner's RBD status.
Special case: surviving spouse
If you're the surviving spouse, you have more options than any other beneficiary:
- Spousal rollover. Roll the inherited IRA into your own IRA. It becomes your account, with your RBD, your RMD calculation, your beneficiaries. Most flexible long-term.
- Treat as inherited. Keep it as an inherited IRA. Useful if you're under 59½ and need to take distributions without the 10% early-withdrawal penalty.
- Disclaim the inheritance. Decline the inheritance within 9 months of death. The IRA then passes to the contingent beneficiary (often the kids). This is sometimes a tax-planning move when the surviving spouse is well-funded and the kids could benefit more.
Strategies that save real money
Three strategies that estate-planning attorneys and CPAs use to optimize inherited retirement accounts:
1. Distribute in low-income years
If you have variable income (consulting, sabbatical year, between jobs, retirement transition), take larger distributions from an inherited Traditional IRA in those years to fill up the lower tax brackets. Then take less in high-income years.
2. Roth conversion of the original owner's IRA before death
If the original owner is still alive and has the ability to do Roth conversions, doing them BEFORE death (subject to the 5-year rule) can convert what would have been a taxable inherited Traditional IRA into a tax-free inherited Roth. This works best when the original owner is in a lower tax bracket than the beneficiaries will be.
3. Charitable beneficiary
For retirement accounts left to charity, the charity receives the full balance income-tax-free (charities don't pay income tax). For families with both charitable goals AND heirs, it can be more efficient to leave the IRA to the charity and other assets to the heirs.
What to do this week
- If you recently inherited a retirement account: talk to a CPA about whether you owe back RMDs and what your 10-year distribution plan should look like. Cost: typically $300–$800 for an initial planning meeting. Savings: often $5,000–$50,000+.
- If your parents have significant retirement assets: have the conversation about beneficiary designations. Make sure contingent beneficiaries are named. If you might qualify as an Eligible Designated Beneficiary, document the qualification basis now.
- If you have your own retirement accounts: review your beneficiary designations annually. Verify primary AND contingent are named. Verify they match your current wishes.
