Key Takeaways
- The plan administrator, not HR, manages the 401(k) payout process.
- The beneficiary form determines who inherits; it overrides the will.
- Most 401(k)s transfer outside of probate, but missing beneficiaries can cause delays.
- Spouses can often roll over funds into their own account; others must use an inherited IRA.
- Families should keep copies of all correspondence and verify tax implications before withdrawing funds.

A 401(k) can be one of the most valuable financial assets someone leaves behind. Yet, many families don’t know where to start once a loved one passes, who to contact, what paperwork to expect, or how to claim the money.
This guide breaks down exactly how the 401(k) process works after death, step by step, and points out where families often get stuck. So, if you have authority to act, you can move through the process with more clarity and confidence.
Step 1: Reporting the Death
The process usually starts with the family or executor contacting the employer’s HR or benefits department. HR confirms the death with a certified copy of the death certificate and then notifies the plan administrator, which is the financial company that manages the account, such as Fidelity, Vanguard, or Empower.
If you know which company holds the 401(k), you can also contact them directly. They’ll confirm what documentation is needed and begin their verification process.
Plan administrators generally ask for the full name of the person who died, the last four digits of their Social Security number, the employer’s name, and the date of death. Once the death is reported, the account is typically frozen to new transactions, while the balance generally stays invested and can rise or fall in value until the claim is paid.
Step 2: Verifying the Beneficiary
Once the plan administrator receives notice, they locate the beneficiary designation form on file. This document decides who inherits the account and always takes priority over what’s written in the will.
If a beneficiary is listed, that person will be contacted directly. If no one is listed, the plan document often directs the account to the surviving spouse by default, though the order depends on the plan’s terms. If the person wasn’t married, it usually becomes part of the estate, which means the account must pass through probate before it can be distributed.
Who Receives the 401(k) and What Happens Next?
| Situation | Who typically receives the account | What happens next |
|---|---|---|
| Beneficiary listed | The named beneficiary, regardless of what the will says | The plan administrator contacts that person directly |
| Spouse is the beneficiary | The surviving spouse | Funds can be rolled into the spouse’s own retirement account, delaying taxes until withdrawal |
| Non-spouse beneficiary | The named beneficiary | Funds generally move into an inherited IRA and are usually withdrawn within ten years |
| No beneficiary listed, person was married | Often the surviving spouse | The outcome depends on the plan’s terms |
| No beneficiary listed, person was not married | The estate | The account usually passes through probate before it is distributed |
Step 3: Filing the Claim
The beneficiary receives a claim packet or secure online link from the plan administrator. They’ll need to submit:
- A certified copy of the death certificate
- Proof of identity, such as a driver’s license or Social Security number
- Relationship documentation, if requested
- Bank account information for payment or rollover
The plan administrator will also ask how the beneficiary wants to receive the funds. This could be as a lump-sum payment, a rollover into an inherited IRA, or installments over time.
Each option carries different tax effects. A lump-sum payment from a traditional 401(k) is taxed as income in the year it is received, which places the full balance in a single tax year. A rollover into an inherited IRA spreads withdrawals across several years, and installments spread the income in a similar way. Many beneficiaries review the choice with a tax professional first, since a processed distribution generally cannot be undone.
Step 4: Processing and Payout
After the paperwork is submitted, the plan administrator reviews and approves the claim. Once processed, the funds are released based on the payout method chosen.
Payout timing varies by plan. Empower, a major plan administrator, reports that beneficiary claims take about one month after all required documents are received, and other plans can take longer, typically a few weeks to a few months depending on the paperwork. If the funds are rolled into an IRA, the transfer is made directly to the receiving financial institution.
Payment arrives in one of two ways. A direct rollover moves from the plan administrator to the inherited IRA custodian without passing through the beneficiary’s hands. A lump-sum payment is typically issued by check or electronic transfer, and federal income tax is often withheld before the funds arrive, so the amount received can be lower than the account balance. Plan administrators generally send a confirmation or transaction statement once payment is complete, and families commonly keep that record with the estate paperwork and tax documents.
Step 5: Taxes and Reporting
401(k) distributions are reported on Form 1099-R, which the beneficiary receives the following January.
Traditional 401(k) funds are taxed as income when withdrawn. Roth 401(k) funds are typically tax-free, provided the account has met certain holding requirements.
Spouses can roll the funds into their own retirement account, which helps delay taxes until withdrawal. Non-spouse beneficiaries generally move the funds into an inherited IRA and usually withdraw the balance within ten years, as described in IRS Publication 590-B.
Step 6: Where Families Get Stuck
Many families run into the same challenges:
- They aren’t aware that a 401(k) exists, especially from an old employer. Families often find clues in old tax forms, pay stubs, or mail from financial institutions, and then contact the former employer’s benefits department.
- The beneficiary form is missing or outdated, sometimes still naming an ex-spouse. The plan administrator keeps the form on file, so families typically request a copy and ask how the plan treats an outdated designation.
- The employer has merged or closed, making it hard to find the plan administrator. Families often trace the plan through the successor company or through the Form 5500 filings described below.
- Tax rules for rollovers and withdrawals are unclear. Families typically confirm the details with the plan administrator or a licensed tax professional before taking any withdrawal.
If you’re not sure who manages the plan, you can look it up using the Department of Labor’s Form 5500 search tool, which lists plan providers by employer. For older accounts, guides on finding unclaimed retirement benefits and IRS records for asset discovery outline other places to search.
What Has Changed for Inherited 401(k)s in 2026?
Annual withdrawals are now part of the picture for many non-spouse beneficiaries. When the person who died had already begun taking required minimum distributions, the beneficiary generally takes a withdrawal each year during the 10-year period, and the account is emptied by the end of the tenth year.
Penalty relief for missed withdrawals in earlier years no longer applies, so the annual requirement is in effect in 2026. A withdrawal for the current year is generally due by December 31.
As Fidelity’s inherited IRA guidance explains, a missed annual withdrawal can carry an IRS penalty of up to 25%.
The exact schedule depends on the account type, the beneficiary’s relationship, and when the original owner died, which a separate overview of inherited IRA distribution rules covers in more detail.
In practice, a beneficiary who inherits through a 401(k) rollover often confirms with the plan administrator or a tax professional whether yearly withdrawals apply before the first one is due.
