Inherited IRA and RMD Rules 2026: The SECURE Act 10-Year Trap

One overlooked rule can turn an inheritance into a tax bill

When someone inherits a parent’s or spouse’s IRA, the first instinct is almost always the same: “I’ll just let it ride like my own retirement account.” My read is that this is exactly where people get burned. The SECURE Act, effective for deaths after 2019, rewrote the rulebook. The old “stretch IRA,” where you sipped from the account over your entire lifetime, is off the table for most beneficiaries today.

Here is the blunt version: the biggest danger with an inherited IRA is not the tax rate, it’s the timing. Miss the deadline to empty the account, or skip a required annual withdrawal you didn’t know you owed, and you get hit twice — an excise tax on what you failed to take out, plus a pile of taxable income crammed into too few years. This guide walks the rules in the order you actually need them, whether you just inherited an account or you’re planning ahead for your heirs.

This is information, not tax or investment advice. Precise dollar figures and your specific answer belong with IRS.gov and a CPA. With that said, let’s get into it.

Figure out your beneficiary type first

Inherited IRA rules branch entirely on who you are. The IRS sorts beneficiaries into three tiers, and getting this wrong throws off everything downstream.

Beneficiary type	Examples	Withdrawal rule
Eligible designated beneficiary (EDB)	Spouse, minor child of owner, disabled or chronically ill person, someone ≤10 years younger than owner	Can still stretch over life expectancy
Designated beneficiary (non-EDB)	Adult children, grandchildren, nieces/nephews, friends	10-year rule
Non-designated beneficiary	Estate, most trusts, charities	5-year rule or owner’s remaining life expectancy

The punchline: most adult children land in that middle tier and are stuck with the 10-year rule. The classic case is a 45- or 55-year-old inheriting a parent’s IRA, and no, they cannot stretch it.

One wrinkle inside the EDB group: a minor child of the owner can use the life-expectancy method until they reach the age of majority (21 for this purpose), and then the 10-year clock starts. A grandchild does not qualify as an EDB even if they’re a minor. Only the owner’s own child does.

The 10-year rule’s hidden trap: annual RMDs

Plenty of people assume “10 years to empty it” means they can leave it untouched for nine years and yank it all out at the end. That assumption is precisely what caused years of confusion until the IRS finalized its regulations. The answer turns on when the owner died.

The dividing line is whether the owner had reached their required beginning date (RBD). Under SECURE 2.0, the RMD age is 73 (rising to 75 in 2033), and the RBD is generally April 1 of the year after the owner turns 73.

When the owner died	Annual RMD in years 1–9	Year 10
On or after RBD	Yes, annual RMD required	Empty the account
Before RBD	Not required	Empty the account
Roth IRA inherited	Not required	Empty the account

So if your parent died at an age where they were already taking RMDs, you inherit a double obligation: take at least the minimum each year starting in year one, and still drain the account by the end of year ten. Skipping those early-year RMDs because nobody mentioned them is one of the most common — and most avoidable — mistakes out there.

Small mercy: the IRS waived the penalty on missed annual RMDs during the years the rules were unsettled (roughly 2021–2024). Those waivers aren’t permanent, so from 2025 onward you should plan as if the rules apply in full.

Spouses get more doors: three paths

A surviving spouse sits in the best seat in the house, with options no other beneficiary gets. Which door you pick shapes decades of tax flow, so it’s worth slowing down here.

Option one: roll it into your own IRA (spousal rollover or transfer). You fold the inherited assets into your personal IRA, and from that point it’s treated as yours — RMDs start at your own RMD age (73), not the deceased’s. If you’re younger than the person you inherited from and don’t need the cash now, this usually wins on deferral, and you get to name your own beneficiaries.

Option two: keep it as an inherited IRA. If you’re under 59½ and need to tap the money, this is often smarter. Withdrawals from an inherited IRA skip the 10% early-withdrawal penalty regardless of your age. It can also help if the deceased spouse was younger than you, letting you base RMD timing on their age.

Option three: take a lump sum. If you need the money now, you can pull it all, but that spikes your taxable income for the year and can push you into a much higher bracket. On a large balance, a chunk simply evaporates to taxes. The lump-sum-versus-spread math mirrors the logic in annuity buyout: lump sum vs annuity.

SECURE 2.0 also added an election letting a surviving spouse be treated as the deceased owner for RMD purposes, which can push the start of RMDs out further. If you’re a spouse, run this option into the comparison too.

What non-spouses must never do

For non-spouse beneficiaries — especially adult children inheriting a parent’s IRA — the fatal mistakes almost all come from moving the account the wrong way.

1) Merging it into your own IRA. Non-spouses can’t do this. Attempt it and the IRS treats the whole balance as distributed and taxable that year, with no undo button.

2) A 60-day rollover. Inherited IRAs don’t allow the 60-day rollover. The only way to move one is a direct trustee-to-trustee transfer. Take a check in hand and try to redeposit it, and you’ve triggered full taxation.

3) Titling the account wrong. An inherited IRA has to be retitled in a specific format, typically “[Deceased’s name] IRA (deceased [date]) FBO [beneficiary’s name].” Botch the title and the account may not be recognized as an inherited IRA at all.

4) Combining accounts from different decedents. An inherited IRA from your father and one from your mother can never be merged. Keep them separate, each running its own clock.

5) Ignoring successor-beneficiary rules. If you inherit an IRA and later die, the next person in line generally continues your remaining 10-year window rather than getting a fresh one. Plenty of people wrongly believe the clock resets.

If a lump sum leaves you short on cash to cover the resulting tax bill, don’t scramble into expensive borrowing — personal loan vs HELOC shows why the total cost matters. Better still, spread withdrawals across years so the tax never lands all at once.

Inherited Roth IRAs: no tax, but still a deadline

Inherited Roth IRAs get written off as “tax-free, so who cares,” and that’s only half right.

Because a Roth owner never takes RMDs during life, the owner is always treated as having died “before the RBD.” That means a non-spouse beneficiary owes no annual RMD in years one through nine — but still has to empty the account by the end of year ten.

On taxes, if the account met the five-year holding requirement, withdrawals are generally federal-income-tax-free. That points to a clear strategy: with no tax due, there’s no reason to rush. You’re usually better off leaving the money to compound tax-free and pulling it in year ten.

If you want to see why a Roth is such a powerful vehicle all the way through to inheritance, a self-directed IRA for real estate investing shows how far the account type can stretch when it’s structured deliberately.

The catch worth repeating: tax-free does not mean deadline-free. Blow past the year-ten mark and you’re squarely in penalty territory just like anyone else.

Missed an RMD? Penalty and how to fix it

The most common accident is simple: “I didn’t know I owed an annual RMD.” The good news is SECURE 2.0 softened the penalty and left a correction path open.

Item	Detail
Old penalty	50% excise tax on the missed amount
Current penalty	Reduced to 25%
If corrected promptly	Drops to 10% within the correction window
How to fix	Withdraw the missed amount immediately → file Form 5329 → attach a reasonable-cause statement

In practice, the moment you discover the miss, take the shortfall out and file Form 5329 requesting a waiver. If the IRS accepts your reasonable cause — an honest oversight, illness, bad advice — it frequently waives the penalty. The key is self-correcting the instant you notice, rather than sitting on it until an audit surfaces it.

Inherited IRA action checklist

Turning the rules into steps in the right order is how you avoid the traps.

• Confirmed the owner’s date of death and whether it was before or after their RBD
• Classified yourself as EDB or non-EDB
• Identified whether the account is Traditional or Roth
• Retitled the inherited IRA in the correct format
• Moved it only via trustee-to-trustee transfer (never took a check)
• Determined whether annual RMDs apply during the 10-year window
• Kept accounts from different decedents separate
• Built a multi-year withdrawal plan to spread the tax on large balances
• Checked state income tax treatment where you live

Any box you can’t check with confidence is a box to run past a CPA or enrolled agent.

A common failure to learn from

Here’s a pattern that shows up constantly. A 55-year-old inherits a sizable Traditional IRA from her father, who died at an age when he was already taking RMDs. She hears “just empty it within 10 years” and takes nothing out for the first three years. Only at tax time does she learn she missed the annual RMDs for years one through three.

Then a second problem stacks on top. She now has to pull a large balance out over the remaining seven years — and she’s a high earner in her peak career, so those withdrawals pile onto her top marginal bracket. Had she started small, steady withdrawals from year one, she could have used the lower brackets each year and cut her total tax bill substantially. This is where knowing the rules versus not knowing them shows up as real dollars.

The lesson is plain: an inherited IRA isn’t just about when you empty it, but when you start and how much you pull each year. Deferring isn’t always the winning move.

Plan for the money once it’s out

An inherited IRA is, ultimately, an account you’re required to drain on a schedule. So it pays to decide in advance where the proceeds go. If you’re spreading withdrawals over several years, you can map out moving each year’s chunk into dividend or growth assets in a taxable account.

The tax mechanics of selling and reinvesting connect to the principles in the capital gains tax guide, and if you’re weighing where to redeploy, a dividend-focused approach like the SCHD dividend ETF guide is one option. And if the inheritance arrived alongside a broader tax mess — back taxes, unfiled years — the IRS Fresh Start program is worth a look before the IRA distributions push your income higher.

Boiled down, the whole thing comes to three moves: pin down your beneficiary type, decide whether annual RMDs apply based on the death date, and build a tax-spread withdrawal plan inside the 10-year window. Nail those three and you head off almost every disaster. And on a big balance, as always, running it past a professional is money well spent.
