What Happens to Your 401(k) When You Die?

7 min read

When you die, your 401(k) doesn't go through your will and it usually doesn't go through probate. It goes to whoever is named on the beneficiary form held by your plan administrator. What happens next depends almost entirely on who that person is.

If your spouse is the beneficiary

A surviving spouse has the most options, and generally the best ones:

  • Roll it into their own IRA. The money is then treated as if it were always theirs — no immediate tax, and withdrawals follow their own timeline.
  • Keep it as an inherited account. Useful if the surviving spouse is under 59½ and needs access, because inherited-account withdrawals avoid the 10% early-withdrawal penalty.
  • Take it as a lump sum. Simple, but the whole amount from a traditional 401(k) is taxable income in one year, which can push them into a much higher bracket.
In most workplace plans your spouse is automatically the beneficiary unless they have signed a written, notarised waiver. Naming someone else on the form is not enough on its own.

If someone other than a spouse inherits

Since the SECURE Act, most non-spouse beneficiaries — adult children, siblings, friends — fall under the 10-year rule: the entire account must be emptied by the end of the tenth year after the year of death. The old "stretch" option, which let people spread withdrawals across their lifetime, is gone for most people.

A narrower group, called *eligible designated beneficiaries*, can still stretch withdrawals over their life expectancy. That includes minor children of the account holder (until they reach majority), disabled or chronically ill beneficiaries, and anyone not more than 10 years younger than the account holder.

Traditional 401(k) withdrawals are taxed as ordinary income to the person receiving them. Roth 401(k) withdrawals are generally tax-free, but the 10-year deadline still applies.

If nobody is named

If the beneficiary form is blank, or every named person has died, the plan's default rules take over. That usually means the money goes to your estate — and then it does go through probate, it is exposed to your creditors, and the payout window typically shortens to five years instead of ten. It is the worst outcome available, and it happens purely by omission.

What your family actually has to do

  1. Contact the plan administrator — not the employer's HR desk, though HR can tell them who it is.
  2. Provide a certified copy of the death certificate and proof of identity.
  3. Choose a distribution option in writing. This choice is often irreversible, so it's worth taking advice first.
  4. Open an inherited IRA if rolling over, and make sure it's titled correctly — a mis-titled rollover can be treated as a full taxable distribution.

The problem nobody plans for

All of that assumes your family knows the account exists. The average person changes jobs many times, and old workplace plans are quietly left behind. Plan administrators don't hunt for beneficiaries — after a long period of no contact, balances are often rolled into a default IRA or handed to the state as unclaimed property. If you've lost track of an old plan yourself, our guide on how to find an old 401(k) walks through the free search tools.

The fix on your side is simple: keep a current list of every retirement account, who administers it, and who's named on it — somewhere your family can actually reach. That's what a digital inheritance vault is for, and it never stores your login details.

Frequently asked questions

Does a 401(k) go through probate?

Not if a living beneficiary is named — it passes directly to them. It only enters probate if the beneficiary form is blank or every named beneficiary has died, in which case it defaults to your estate.

How long does a beneficiary have to withdraw an inherited 401(k)?

Most non-spouse beneficiaries must empty the account within 10 years of the year of death. Spouses and certain eligible designated beneficiaries have longer options.

Is an inherited 401(k) taxable?

Withdrawals from an inherited traditional 401(k) are taxed as ordinary income to the beneficiary. Roth 401(k) withdrawals are generally tax-free, though the 10-year deadline still applies.

Can my spouse be cut out of my 401(k)?

Usually not by default. Most workplace plans require a spouse to sign a notarised waiver before someone else can be named as the primary beneficiary.
