Educational, Tax, and Estate-Planning Disclosure: This article is provided for general educational purposes only. It does not constitute retirement, investment, tax, legal, estate-planning, or financial advice. State Employee Advisor Network is a marketing and referral platform operated by Revenx LLC. SEAN does not administer 401(k) plans, determine beneficiary rights, prepare estate documents, calculate inherited-account distributions, or provide individualized financial recommendations. Official requirements should be confirmed with the applicable plan administrator, IRS, attorney, tax professional, or another qualified source.

A 401(k) beneficiary is the person or entity entitled to receive plan benefits after the participant dies.

Naming beneficiaries is an important administrative step because 401(k) assets may represent a significant part of a household's retirement savings.

Possible beneficiaries may include:

  • Spouse
  • Adult child
  • Minor child
  • Parent
  • Sibling
  • Other individual
  • Trust
  • Charity
  • Estate

However, beneficiary rights are not determined simply by writing someone's name in a will.

401(k) plans operate under federal law and their governing plan documents. Spouses may receive special protections, distribution rules can differ among beneficiaries, and the tax treatment of inherited accounts depends on several factors.

What Is a 401(k) Beneficiary?

A beneficiary is generally a person or entity designated under the plan's procedures to receive the account after the participant dies.

The plan may allow:

  • One primary beneficiary
  • Multiple primary beneficiaries
  • One or more contingent beneficiaries

A participant may also be able to allocate percentages among multiple beneficiaries.

For example:

  • Spouse: 70%
  • Charity: 20%
  • Adult child: 10%

Whether that allocation is permitted and whether spousal consent is required should be confirmed with the plan administrator.

Primary vs. Contingent Beneficiaries

Primary beneficiary

The primary beneficiary is generally first in line to receive the account.

For a married participant, federal spousal protections can affect who may be named.

Contingent beneficiary

A contingent beneficiary generally receives the benefit if no primary beneficiary is entitled to receive it.

This may occur when a primary beneficiary:

  • Dies before the participant
  • Disclaims the inheritance
  • Is otherwise unable to receive the benefit under plan terms

Naming contingent beneficiaries can help avoid uncertainty when the primary beneficiary is no longer available.

Spouses Have Special Rights

The live article correctly recognizes that spouses receive special protection but oversimplifies how the rule works.

The Department of Labor explains that in most 401(k) and other defined-contribution plans, if the participant dies before receiving benefits, the surviving spouse will generally receive them automatically.

If the participant wants someone else to receive the benefit, the spouse generally must consent to the change under the applicable plan procedures.

That consent typically must be witnessed by:

  • A notary, or
  • A plan representative

The plan's own forms should be used.

A participant should not assume an informal letter or will is sufficient to waive a spouse's rights.

Marriage Can Change an Existing Beneficiary Designation

Suppose someone names a parent as beneficiary while single.

The employee later marries but never updates the 401(k).

The new spouse may receive rights under federal law and the plan even though the old beneficiary form still lists the parent.

This is why beneficiary records should generally be reviewed after:

  • Marriage
  • Divorce
  • Remarriage
  • Birth or adoption
  • Death of a beneficiary
  • Retirement
  • Major estate-plan changes

The Department of Labor specifically advises participants who marry after enrolling in a plan to notify the employer or plan administrator and update their status.

What Happens After Divorce?

Divorce requires special attention.

Do not assume a former spouse is automatically removed from every retirement benefit simply because a divorce decree was entered.

Potentially relevant documents can include:

  • Beneficiary form
  • Divorce decree
  • Plan document
  • Qualified domestic relations order
  • Spousal waiver

A qualified domestic relations order, commonly called a QDRO, may assign certain retirement-plan rights to a spouse, former spouse, child, or other dependent.

Because these questions involve plan and legal rights, the administrator and an appropriately qualified attorney may need to be involved.

Who Can Be Named if You Are Single?

An unmarried participant generally has greater flexibility in selecting beneficiaries, subject to plan terms.

Potential choices may include:

  • Children
  • Parents
  • Siblings
  • Friends
  • Trust
  • Charity
  • Estate

The live article suggests virtually anyone can be named.

That is generally directionally correct, but the plan's beneficiary procedures still control.

The participant should confirm that:

  • The beneficiary is permitted
  • The designation is complete
  • Percentages add up correctly
  • The plan accepted the form

Can a Minor Child Be a 401(k) Beneficiary?

Yes, a minor can generally be named when the plan permits it.

The live article says minors cannot inherit a 401(k) directly and that a trust must be created.

That is too absolute.

The larger issue is that a minor generally cannot independently control inherited assets.

Depending on:

  • State law
  • Account value
  • Plan procedures
  • Existing custodial arrangements

the assets may need to be managed through a:

  • Guardian
  • Custodian
  • Trust
  • Other legally authorized arrangement

Court involvement is possible in some cases, but it is not automatic in every situation.

Parents considering a minor beneficiary may want to coordinate the designation with an estate-planning attorney.

Can a Trust Be a Beneficiary?

Yes, when allowed by the plan.

A trust may be considered when there are concerns involving:

  • Minor children
  • Special-needs beneficiaries
  • Asset management
  • Distribution control
  • Estate-planning goals

But trusts introduce additional tax and retirement-plan complexity.

For required minimum distribution purposes, a trust does not automatically receive the same treatment as an individual beneficiary.

Federal rules determine whether trust beneficiaries can be treated as designated beneficiaries.

The trust document and retirement-account beneficiary designation should therefore be coordinated carefully.

What if No Beneficiary Is Named?

This is another area where the live article is too categorical.

If there is no valid beneficiary designation, the plan's default beneficiary provisions generally determine who receives the benefit.

The default could potentially be:

  • Surviving spouse
  • Children
  • Estate
  • Another category specified by the plan

The live article says the account necessarily goes through probate before reaching the default beneficiary.

That is not universally correct.

If the plan document identifies a surviving spouse or another person as the default beneficiary, the benefit may be paid under the plan rather than first becoming a probate asset.

If the estate becomes the beneficiary, probate and estate administration may become relevant.

Employees should review the Summary Plan Description for the actual default-beneficiary rule.

Does a Will Override a 401(k) Beneficiary?

Generally, a will does not simply replace the beneficiary designation maintained by the retirement plan.

401(k) benefits are determined under:

  • Plan terms
  • Valid beneficiary designations
  • Federal spousal protections
  • Applicable QDROs
  • Federal law

Estate-planning documents should therefore be coordinated with retirement-account beneficiary forms rather than treated as substitutes for them.

What Can a Surviving Spouse Do With an Inherited 401(k)?

A surviving spouse generally has more options than many other beneficiaries.

Depending on the plan and circumstances, potential options can include:

  • Leave assets in the employer plan
  • Receive distributions
  • Take a lump sum
  • Complete an eligible rollover to an IRA
  • Roll eligible assets to another qualified plan
  • Use inherited-account treatment

The plan document determines which options are actually available.

The IRS specifically notes that qualified plans may give a spousal beneficiary more choices than a non-spouse beneficiary.

Spousal RMD Rules Are Not Simply “Wait Until 73”

The live article says a surviving spouse can simply delay RMDs until age 73.

That is too broad.

Distribution timing can depend on:

  • Participant's age at death
  • Whether the participant had reached the required beginning date
  • Whether the spouse is the sole beneficiary
  • Whether the spouse keeps inherited treatment
  • Whether assets are treated as the spouse's own
  • Plan terms

A surviving spouse should confirm which set of rules applies before choosing a rollover or distribution method.

Non-Spouse Beneficiaries

A non-spouse beneficiary generally has different rollover options.

Potential choices may include:

  • Lump-sum distribution
  • Leaving funds in the employer plan when permitted
  • Direct transfer to an inherited IRA
  • Distributions under applicable beneficiary RMD rules

A non-spouse beneficiary generally cannot simply roll inherited 401(k) assets into their own personal IRA and treat the money as if they had always owned it.

An eligible direct rollover generally goes to a properly titled inherited IRA.

What Is an Eligible Designated Beneficiary?

Current federal rules distinguish certain beneficiaries from other designated beneficiaries.

An eligible designated beneficiary generally includes:

  • Surviving spouse
  • Minor child of the deceased participant
  • Disabled individual
  • Chronically ill individual
  • Individual not more than 10 years younger than the participant

These beneficiaries may qualify for different distribution treatment.

The live article says people “10 years younger” are exempt.

The more accurate standard is someone not more than 10 years younger than the participant.

Minor Children and the 10-Year Rule

A participant's minor child may initially qualify as an eligible designated beneficiary.

However, that special status does not continue indefinitely.

Once the child reaches the applicable age of majority for these federal rules, the remaining account generally becomes subject to a 10-year distribution period.

This treatment applies specifically to a child of the deceased participant.

It should not automatically be extended to every minor beneficiary.

How Does the 10-Year Rule Work?

For many individual designated beneficiaries who are not eligible designated beneficiaries, the inherited account generally must be fully distributed by the end of the tenth year following the participant's death.

For example, if the participant dies in 2026, the applicable outside deadline generally falls at the end of:

2036

But the live article incorrectly says the IRS never requires annual withdrawals during the 10-year period.

The rule depends partly on when the participant died relative to the required beginning date.

When Annual RMDs May Apply During the 10-Year Period

Final IRS regulations clarify an important distinction.

If the participant dies before the required beginning date and the beneficiary is subject to the 10-year rule, the beneficiary generally does not have to take annual RMDs during years 1 through 9 solely under that rule.

The account must still be fully distributed by the end of year 10.

However, if the participant dies on or after the required beginning date and the beneficiary is subject to the 10-year rule, annual RMDs generally continue during the 10-year period, with the remaining account emptied by the deadline.

That makes the live article's statement that someone can always wait until the tenth year inaccurate.

The 50% Penalty Is Outdated

The live article says failing to empty the account within 10 years creates a 50% penalty.

That reflects older required-minimum-distribution penalty rules.

Current federal law generally provides a 25% excise tax for an RMD shortfall.

The rate may potentially be reduced to 10% when the shortfall is corrected within the applicable correction period.

The actual penalty depends on what distribution was required and whether correction rules apply.

Are Inherited 401(k) Withdrawals Taxable?

Traditional pretax 401(k) distributions are generally taxable to the beneficiary when received.

Tax consequences can depend on:

  • Amount distributed
  • Account's tax character
  • Beneficiary's other income
  • State tax rules

For example, taking an entire traditional 401(k) in one year may create a very different tax result from taking distributions across several years.

That does not mean spreading distributions is always preferable.

Required distributions, cash needs, and tax circumstances should all be considered.

What About an Inherited Roth 401(k)?

Roth treatment requires separate analysis.

Designated Roth accounts generally do not require lifetime RMDs for the original owner under current law.

Beneficiary RMD rules still apply after death.

Qualified Roth distributions may generally be tax-free, but qualification requirements and the age of the Roth arrangement can matter.

A beneficiary should not assume every inherited Roth payment is automatically tax-free.

Early-Distribution Tax for Beneficiaries

The live article says surviving spouses over age 59½ avoid the early-withdrawal penalty.

That misses an important distinction.

Distributions received by a beneficiary after the participant's death generally have a separate exception from the federal 10% additional tax.

Age 59½ is therefore not the only relevant rule.

However, a surviving spouse who rolls inherited assets into an account treated as the spouse's own can later become subject to the ordinary rules applicable to that account.

That can matter when the spouse is younger than 59½.

State Employees May Need Multiple Beneficiary Reviews

A state employee's 401(k) designation does not automatically control other workplace benefits.

Separate beneficiary or survivor elections may exist for:

  • Defined-benefit pension
  • 403(b)
  • Governmental 457(b)
  • 401(a)
  • Life insurance
  • Other employer benefits

A pension may also require a separate survivor election at retirement.

These records should be reviewed individually rather than assuming one beneficiary form covers everything.

Readers can review the site's 403(b) vs. 401(k) comparison for additional employer-plan background.

Final Thoughts

Naming a 401(k) beneficiary is an important part of retirement and estate coordination, but the rules are more detailed than the live article suggests.

Important distinctions include:

  • Spouse vs. non-spouse
  • Eligible designated beneficiary vs. other beneficiary
  • Individual vs. trust or estate
  • Death before vs. after the required beginning date
  • Traditional vs. Roth assets

The plan document is also important because it determines available distribution options and default beneficiaries.

Review beneficiary designations after major life events and coordinate them with pension survivor elections, other retirement accounts, life insurance, and estate documents.

FAQs

Who Can Be a 401(k) Beneficiary?

Depending on plan rules, a beneficiary may be a spouse, child, other individual, trust, charity, estate, or another permitted entity.

Does a Spouse Automatically Receive a 401(k)?

In most 401(k) plans, surviving spouses receive special protection. Naming someone else generally may require valid spousal consent.

Can a Minor Child Inherit a 401(k)?

Yes, but a minor generally cannot independently manage the assets. A guardian, custodian, trust, or other arrangement may be needed.

Does a 401(k) Always Go Through Probate if No Beneficiary Is Named?

No. The plan's default-beneficiary provision determines who receives the account. Probate may become relevant if the estate is the beneficiary.

What Is the 10-Year Rule?

Many designated beneficiaries who are not eligible designated beneficiaries must fully distribute the inherited account by the end of the tenth year after death.

Are Annual Withdrawals Required During the 10-Year Rule?

Sometimes. If the participant died on or after the required beginning date, annual RMDs generally may be required while the account must also be emptied by the end of year 10.

Is the Penalty for Missing an RMD Still 50%?

No. Current federal law generally uses a 25% excise tax, potentially reduced to 10% when correction requirements are satisfied.

When Should 401(k) Beneficiaries Be Reviewed?

Review them after marriage, divorce, remarriage, birth or adoption, death of a beneficiary, retirement, and major estate-plan changes.
