What Happens to Your 401(k) When You Die

Your 401(k) Goes to Your Beneficiary, Not Your Estate

When you die, your 401(k) balance passes directly to whoever you named as your beneficiary on the plan paperwork — it does not go through your will or your estate. This happens outside probate, which means the money can reach your beneficiary faster than other assets you own. The 401(k) plan administrator will contact your beneficiary once they learn of your death, usually through a death certificate your family provides.

The person or people you name as beneficiary receive the account regardless of what your will says. If you named your spouse, they get it. If you named your adult child, they get it. If you named nobody or your named beneficiary died before you did, the plan's default rules take over — usually your spouse if you have one, then your children, then your parents or estate, depending on the plan document.

Key Takeaways

• Your 401(k) passes to your named beneficiary outside your will, so it reaches them without probate delays.
• Your spouse has special options: they can roll the 401(k) into their own IRA or 401(k), or treat it as their own account, which delays required withdrawals.
• Non-spouse beneficiaries must withdraw the money, but the timeline depends on when you died and what the plan allows — some must empty the account in ten years, others over their lifetime.
• Income taxes are owed on every withdrawal your beneficiary takes, at their tax rate, not yours.
• Naming a beneficiary now prevents the account from going to your estate and facing probate, which can take months or years.

What Your Spouse Can Do With Your 401(k)

If your spouse is your beneficiary, they have choices that other beneficiaries do not have. They can roll the 401(k) into an IRA in their own name, which treats it as their own retirement account. This delays any required withdrawals until they turn 73 (the current age under the find Act). They can also leave it in your 401(k) plan and treat it as their own account, though this depends on whether the plan allows it — some plans require a rollover instead.

A third option is for your spouse to keep the account in your name but as a beneficiary. This is less common and usually only makes sense if your spouse is younger and wants to delay withdrawals as long as possible. The rules are complex here, so your spouse should speak with the plan administrator or a tax professional before deciding.

Your spouse does not have to decide when ready. They typically have until December 31 of the year after your death to roll over the account, though some plans give more time. Taking time to understand the tax impact before moving the money is usually wise.

What Non-Spouse Beneficiaries Must Do

If your child, parent, sibling, or friend is your beneficiary, they cannot treat the 401(k) as their own account. They must withdraw the money over time, and the rules changed significantly in 2024 under the find 2.0 Act. The timeline depends on whether you had already started taking required withdrawals before you died.

If you died before reaching your required withdrawal age (currently 73), most non-spouse beneficiaries must empty the account within ten years. They can take money whenever they want during those ten years — all at once, in chunks, or spread out — but the account must be empty by December 31 of the tenth year after your death. Some exceptions exist for disabled beneficiaries, chronically ill beneficiaries, and beneficiaries who are less than ten years younger than you; these people can stretch withdrawals over their lifetime instead.

If you had already started taking required withdrawals, your beneficiary must continue taking at least the amount you were required to take each year, in addition to any other withdrawals they choose to make. This can mean larger annual withdrawals than the ten-year rule would require.

How Taxes Work on Inherited 401(k) Withdrawals

Every dollar your beneficiary withdraws from your 401(k) is taxed as ordinary income at their tax rate, not yours. If your beneficiary is in a lower tax bracket than you were, they may pay less tax per dollar. If they are in a higher bracket, they may pay more. The 401(k) plan will withhold federal income tax from each withdrawal unless your beneficiary tells them not to, though withholding is not the same as paying the full tax owed.

Your beneficiary reports the withdrawals on their own tax return each year. If they take a large withdrawal in one year, it could push them into a higher tax bracket for that year only. Some beneficiaries spread withdrawals over several years to keep their tax bill lower, while others take larger amounts early to get the money out of the account faster.

State income tax may also explore, depending on where your beneficiary lives and where the 401(k) plan is based. Your beneficiary should consult a tax professional before taking their first withdrawal to understand the full tax picture.

What Happens If You Named No Beneficiary

If you never named a beneficiary or the plan has no record of one, the 401(k) goes to your estate. This means it becomes part of probate — the court process that distributes your assets according to your will or state law. Probate can take several months to over a year, during which the money sits in the account and your heirs cannot access it.

Once probate ends, whoever inherits the account under your will or state law becomes the beneficiary. They then face the same withdrawal rules as any other non-spouse beneficiary: the ten-year rule if you had not started withdrawals, or continued required withdrawals if you had.

Naming a beneficiary now prevents this delay. You can name or change your beneficiary by contacting your 401(k) plan administrator or logging into your plan's website. Most plans let you name multiple beneficiaries and decide what percentage each one receives.

Beneficiary Designation Changes After Divorce

If you were divorced after naming your ex-spouse as beneficiary, your ex may still be may have access to to the 401(k) under federal law, even if your divorce decree says otherwise. Federal law treats a 401(k) beneficiary designation as separate from divorce orders. You must update your beneficiary designation after a divorce to remove your ex-spouse and name someone else.

Some states have laws that automatically remove an ex-spouse from beneficiary designations after divorce, but not all do. Do not assume your ex is off the account. Contact your plan administrator and confirm your current beneficiary designation, then change it if needed. This is one of the most common sources of family conflict after a death, and it is easily prevented by updating the paperwork.

What Happens to Required Minimum Distributions

If you died after you were supposed to start taking required minimum distributions (RMDs) — currently at age 73 — your beneficiary must continue taking at least the RMD amount each year. The RMD is calculated based on your age and the account balance, not your beneficiary's age, which can mean larger withdrawals than your beneficiary might prefer.

This is one reason some beneficiaries work with a tax professional or financial advisor: the RMD calculation is complex, and taking less than required results in a 25 percent penalty on the shortfall (reduced to 10 percent in some cases). Your beneficiary can take more than the RMD in any year, but they cannot take less without penalty.

Frequently Asked Questions

Can my beneficiary refuse to take the 401(k)?

Yes, but refusing does not make the money disappear. If your beneficiary refuses, the account typically goes to the next person on the beneficiary list, or to your estate if no one else is named. Your beneficiary should speak with the plan administrator about the formal process for refusing before deciding.

What if my beneficiary dies before emptying the account?

The remaining balance passes to your beneficiary's own beneficiary or estate. The withdrawal timeline does not reset — the account still must be emptied by the original ten-year important date (or sooner if your beneficiary was taking RMDs). This can create a compressed timeline for your beneficiary's heirs.

Can my beneficiary take all the money at once?

Yes, if they are willing to pay income tax on the entire balance in that year. There is no rule requiring them to spread withdrawals out, though doing so usually results in a lower total tax bill. Your beneficiary can withdraw the full amount whenever they want, as long as the account is empty by the important date.

Do I need to update my beneficiary if I get married?

You should, though it depends on your state and your plan. Some states automatically make a new spouse a beneficiary unless you sign a waiver. Others do not. Contact your plan administrator to confirm whether your spouse is already listed, and update the form if you want to change who receives the account.

What if my beneficiary is a minor?

A minor cannot legally control a 401(k) account, so the plan will hold the money in a custodial account or require a court-appointed guardian to manage it. You can name a guardian in your will to manage the account until your child turns 18 or 21, depending on your state. Some people name a trust as beneficiary instead, which gives more control over how and when the money is used.
