Inherited a 401(k)? Learn who actually handles it, your options by relationship type, the SECURE Act 10-year rule, and what to do if no beneficiary was named.
When Jennifer's father passed away last spring, she found a 401(k) statement in his filing cabinet and froze. She had no idea who to call. Her father's attorney had explained probate and the will. The financial advisor was focused on the investment accounts. Nobody had explained the 401(k), what it was, who was supposed to claim it, or what the rules were.
Here's what this guide covers: who actually handles a 401(k) after someone dies, what your options are based on your relationship to the deceased, and a rule change that took effect in 2025 that most people haven't heard about. If you're also settling the broader estate, you'll want to read the section at the end, because the 401(k) is just one piece of what's waiting for you.
Most families hit the same wall. A 401(k) can be one of the most valuable assets a person leaves behind. Knowing how to handle a 401(k) after someone dies—the rules, the options, and the pitfalls—can mean the difference between a smooth claim and a costly mistake.
In most cases, no.
Does the Executor Handle the 401(k)?
, not through the will, not through probate court. The person named on the beneficiary designation form is the one who contacts the plan administrator and handles the claim.
The executor's role here is limited. You may help locate the account paperwork, notify the plan administrator of the death, and assist the beneficiary in gathering required documents. But the decisions belong to the beneficiary.
The exception: If no beneficiary was ever named, or if all named beneficiaries have already died, the 401(k) typically enters the estate. In that case, the executor takes over and handles it through the probate process. (This is covered in detail below, it's a situation you want to identify quickly.)
Start here: find out who is named as beneficiary. That one fact determines everything else.
Before you can do anything, you need to find the account.
Start with the obvious: paper files, filing cabinets, email folders, and financial statements. Look for IRS Form 5498, which is mailed annually to retirement account holders and lists the institution and account type. Old tax returns may also reference the account.
If you can't find documentation, contact the deceased's employer HR department directly. For older accounts from past jobs, search the National Registry of Unclaimed Retirement Benefits, a free database where employers register accounts of former employees they've lost contact with.
Keep in mind: there is no single government database of 401(k) accounts. If your loved one worked multiple jobs over the years, there may be separate accounts at multiple institutions. Check every employer from at least the past 10 years.
Once you've found the account, notify the plan administrator, the financial institution or company that manages the 401(k).
For an active employer plan, start with HR. For a rolled-over or individual account, contact the financial institution directly. Have the following ready before you call:
The plan administrator will confirm your status as beneficiary and send you a claims packet. This packet explains the distribution options available to you. Those options depend significantly on your relationship to the account holder, which brings us to the most important section.
Expect 4 to 12 weeks for the full process, from first contact to receiving funds. Submitting complete paperwork upfront is the fastest way to avoid delays.
This is where 401(k) inheritance gets genuinely complicated. The rules are different for spouses, non-spouse beneficiaries, and a small category of people who qualify for exceptions.
Spouses have more flexibility than anyone else. Your three main options are:
Don't rush this decision. Spouses have time. Talk to a financial advisor before choosing.
Adult children, siblings, parents, and other non-spouse beneficiaries face stricter rules under the SECURE Act of 2019.
Your main options are:
The critical rule for non-spouse beneficiaries: the 10-year rule. You must fully withdraw the inherited 401(k) within 10 years of the account holder's death. There is no option to stretch distributions over your lifetime, unless you qualify as an eligible designated beneficiary (see below).
The penalty for violating the 10-year rule is a 50% excise tax on any amount that should have been withdrawn but wasn't. That's not a number to ignore.
Certain beneficiaries are exempt from the 10-year rule and can take distributions over their lifetime instead:
If you fall into one of these categories, the rules are more favorable. Work with a financial advisor to determine your specific situation and optimal strategy.
Here's the part that trips up many families, and that most articles skip entirely.
The original SECURE Act introduced the 10-year rule for non-spouse beneficiaries. Then SECURE Act 2.0 added a clarification that changed how the rule works in practice. The change took effect in 2025.
The old assumption: Most people assumed the 10-year rule just meant you had to empty the account by year 10. You could let it sit and take one big distribution at the end.
The actual rule starting in 2025: If the person who died had already reached their required beginning date, meaning they were already legally required to take annual minimum distributions from their own account, then you as a non-spouse beneficiary must also take annual required minimum distributions during the 10-year window. You cannot wait until year 10 and take it all at once.
The required beginning date is generally April 1st of the year after the account holder turns 73.
In plain language: if your parent was 75 when they died, they had already started taking required distributions. That means you need to take annual withdrawals too, every year until the account is empty or the 10-year window closes.
If your parent was 65 when they died and hadn't started required distributions, you have more flexibility. You can take distributions on your own schedule within the 10-year window.
This rule is new, and many families, and even some advisors, aren't fully aware of it. Before you decide on a distribution strategy, talk to a CPA or financial advisor who is current on the SECURE Act 2.0 regulations.
Inheriting a 401(k) does not trigger an immediate tax bill. Taxes apply when you take distributions.
Here's how it works by account type:
One important relief for beneficiaries: there is no 10% early withdrawal penalty for inherited accounts, regardless of your age. Even if you're 35 years old taking distributions from an inherited 401(k), the early withdrawal penalty doesn't apply.
The main risk for non-spouse beneficiaries is tax bunching, taking large distributions in years when your own income is already high. For a sizeable account, a financial advisor can help you spread distributions across the 10-year window in a way that minimizes the tax hit each year.
For specific tax advice, work with a CPA. This section gives you the framework. Your accountant gives you the numbers.
This is the scenario families least want to find themselves in, and it happens more often than you'd expect.
David's family found out the hard way. His mother had set up her 401(k) 22 years earlier and named her first husband as beneficiary, a husband she had divorced 18 years before she died. By the time she passed, her ex-husband had also died. There was no contingent beneficiary listed. The account defaulted to the estate.
What followed was eight months of probate proceedings before the family could access any of the funds. Legal fees reduced the final amount. The tax treatment available to named beneficiaries didn't apply.
If no beneficiary was ever named, or all named beneficiaries have predeceased the account holder, the 401(k) typically enters the estate and goes through probate. The executor must be appointed by the court, and the account can be frozen until probate resolves.
What to do if this is your situation:
The practical lesson for anyone who is still alive and reading this: check your retirement account beneficiary designations today, and name a contingent beneficiary. It costs nothing and takes ten minutes.

Most 401(k) inheritance errors are irreversible and expensive. Here's what to watch for:
Once the 401(k) is located, the beneficiary is notified, and the claim is in motion, most executors feel like they've cracked the hardest part. The financial accounts are moving forward.
Here's what nobody tells you: the executor's work is far from done.
Beyond financial accounts, the average executor manages more than 70 account closures, cancellations, and government notifications. Utilities are still running. Streaming subscriptions are still billing. Social Security, Medicare, and the DMV all need to be notified. Social media accounts need to be closed or memorialized. Credit bureaus need a deceased alert. The employer needs to coordinate a final paycheck and benefits closure.
None of that gets handled by the financial advisor. None of it gets handled by the probate attorney. It lands on the executor, along with everything else.
AnnCare handles those 50+ non-financial closures directly, and coaches you through the financial ones like bank accounts and investment transfers. Everything for $699 flat, no hourly billing, no percentage of the estate. See what's included in AnnCare's executor assistance service and whether it's right for your situation.
Handling a 401(k) after someone dies comes down to three questions: Who is the named beneficiary? What is their relationship to the deceased? And had the account holder already started required minimum distributions?
Here's a quick recap of what's most important:
Get a financial advisor and CPA involved before choosing your distribution method. The decisions made in the first few weeks have consequences that last a decade.
Once the 401(k) strategy is set, use our executor checklist for the first 30 days to work through the rest of the estate systematically. Most executors are surprised by how much administrative work remains after the financial accounts are handled. If 80 hours of phone calls, paperwork, and coordination sounds like more than you can take on right now, AnnCare handles that work for you, for $699 flat.
