Beneficiary Designations: 401(k), IRA, HSA & Life Insurance

Beneficiary Designations Explained: How to Coordinate Your 401(k), IRA, HSA, and Life Insurance in 2026

A carefully written will does not necessarily determine who receives your retirement accounts, health savings account, or life insurance proceeds. These assets generally transfer under beneficiary forms and the terms of the applicable plan, account, or policy. If a designation is missing or outdated, a substantial part of your estate could go to an unintended person or become subject to estate administration.

A beneficiary designation audit helps ensure that your 401(k), IRA, HSA, and life insurance support one coordinated plan. That does not mean naming the same beneficiaries or using the same percentages on every account. The goal is to make deliberate choices based on family needs, taxes, account rules, and how each asset transfers after death.

This article provides general educational information for U.S. readers, not individualized legal, tax, or financial advice. Federal law, state law, plan documents, account agreements, and personal circumstances can change the result.

Why Beneficiary Designations Can Matter More Than Your Will

Assets such as 401(k)s, IRAs, HSAs, life insurance policies, annuities, payable-on-death accounts, and transfer-on-death accounts generally pass by contract. When a valid beneficiary designation is on file, the provider normally pays the named beneficiary without following the distribution instructions in the account owner’s will.

Consider someone who divorces, remarries, and signs a new will leaving everything to the current spouse. If an old retirement-account form still names the former spouse, the plan administrator or custodian may be required to pay the former spouse. Signing a new will does not automatically replace the beneficiary form.

Outdated or incomplete forms can also cause problems when:

• A named beneficiary has died and no contingent beneficiary is listed.
• A former spouse remains listed after a divorce.
• A child was born or adopted after the designation was completed.
• The owner used an unclear description such as “my children.”
• The owner assumed a revocable trust controlled the account even though the trust was never named on the provider’s form.
• No valid beneficiary is listed, requiring the provider to apply its default provisions.

The outcome is not universal. Account agreements, employer-plan documents, insurance contracts, federal ERISA requirements, and state law can all affect who receives an asset. Some state laws may revoke certain former-spouse designations after divorce, but relying on automatic revocation is risky, particularly when federal law controls an employer plan.

The Core Beneficiary Terms to Know

Primary beneficiary

A primary beneficiary is the first person or entity entitled to receive an asset after the owner’s death. The owner may name one primary beneficiary or divide the asset among several people, trusts, charities, or other permitted recipients.

Contingent beneficiary

A contingent beneficiary receives the asset if no primary beneficiary is eligible to receive it under the provider’s rules. Naming a contingent beneficiary can reduce the risk that the asset defaults to the owner’s estate after the primary beneficiary dies first or disclaims the inheritance.

Percentage allocation

When multiple beneficiaries are named at the same level, the form usually requires a percentage for each. Primary allocations normally must total 100%, and contingent allocations generally must total 100% separately.

One simple designation might read:

• Spouse as primary beneficiary: 100%
• Child A as contingent beneficiary: 50%
• Child B as contingent beneficiary: 50%

Do not assume that the provider will divide an account equally when percentages are omitted. An incomplete form may be rejected or interpreted under the plan’s administrative procedures.

Default beneficiary provisions

A plan, account, or policy may specify who receives the asset when no valid designation exists. Its default order might begin with a surviving spouse, followed by children, other relatives, or the owner’s estate. Each provider can use different provisions, so the default should be confirmed from the controlling documents.

Individuals, trusts, and estates

Naming an individual is often administratively straightforward, but the individual generally receives direct control of the proceeds. Naming multiple individuals allows the owner to allocate percentages, although the form should address what happens if one beneficiary dies first.

A properly drafted trust may provide management, creditor protection, or distribution controls for children, beneficiaries with special needs, or family members who should not receive unrestricted control. Trust designations are more complex for retirement accounts because the trust’s terms and federal tax requirements can affect distribution options and deadlines.

Naming an estate may fit a specific estate plan, but it can also bring the asset into probate, expose it to estate creditors, increase administrative costs, and reduce planning flexibility. It should be a deliberate decision rather than the accidental result of leaving a form blank.

Per stirpes versus per capita

Per stirpes generally means that a deceased beneficiary’s share passes to that beneficiary’s descendants. If two children are named equally and one dies first leaving two children, those grandchildren would typically divide their parent’s 50% share.

Per capita generally divides the asset among the beneficiaries who survive at the specified generation or level. Definitions can vary by provider and state law, so review the language on the actual form instead of relying only on the label.

Where the provider permits, record each beneficiary’s full legal name, date of birth, address, relationship, and requested identifying information. Precise information makes it easier for the provider to identify and locate the intended recipient.

How 401(k) Beneficiary Rules Work in 2026

Most private-sector 401(k) plans are governed by the federal Employee Retirement Income Security Act, or ERISA. Married participants generally face federal spousal-protection rules. A surviving spouse is ordinarily entitled to the account unless the spouse properly consents to the designation of another beneficiary under the plan’s procedures.

Consent commonly must be written and witnessed by a plan representative or notary. A casual letter, prenuptial agreement, divorce decree, revocable trust, or statement in a will may not satisfy the plan’s beneficiary procedures.

These federal protections distinguish many employer plans from IRAs, which generally do not have the same federal spousal-consent requirement. State marital-property law can still affect an IRA, however.

For each 401(k), take these practical steps:

1. Download or request the current Summary Plan Description.
2. Request confirmation of the beneficiary designation on file from the plan administrator.
3. Verify whether electronic designations are accepted and whether spousal consent is required.
4. Confirm how the plan handles divorce, remarriage, deceased beneficiaries, and incomplete allocations.
5. Save the provider’s confirmation, not merely a blank or submitted form, with the estate-planning records.

If no valid beneficiary is listed, the plan applies its default order. The account might pass to a surviving spouse, children, or the participant’s estate. Payment to an estate can require probate and may affect the account’s distribution timeline. The controlling plan documents, rather than the participant’s will alone, determine the result.

IRA Beneficiaries: Spouse, Children, Trust, or Estate

Traditional and Roth IRAs generally pass according to the beneficiary designation maintained by the IRA custodian. A will normally controls an IRA only if the estate becomes the beneficiary under the designation or custodial agreement.

Surviving spouse

A surviving spouse has options that are not generally available to other beneficiaries. Depending on the circumstances, a spouse may be able to treat the IRA as the spouse’s own, complete a spousal rollover, or maintain an inherited IRA.

The best option can depend on the spouse’s age, cash needs, required minimum distributions, the original owner’s age at death, and possible early-withdrawal consequences. A spouse should understand the tax effects before moving or retitling the account.

Children and other non-spouse individuals

Many non-spouse beneficiaries must empty an inherited IRA by the end of the tenth year after the original owner’s death. The 10-year deadline does not always mean that a beneficiary can wait until year 10 without taking earlier distributions.

Under the IRS final regulations issued in July 2024, annual required minimum distributions are mandatory during the 10-year period when the original account owner died on or after the owner’s required beginning date. The remaining balance generally must still be distributed by the end of year 10. Beneficiaries should calculate each deadline carefully rather than treating the rule as a single withdrawal deadline.

Certain eligible designated beneficiaries may qualify for different distribution treatment. These categories include:

• A surviving spouse.
• A minor child of the original account owner.
• A disabled individual who satisfies the applicable requirements.
• A chronically ill individual who satisfies the applicable requirements.
• An individual who is not more than 10 years younger than the original owner.

For this purpose, a minor child of the account owner generally receives eligible-designated-beneficiary treatment only until age 21, regardless of the age of majority under state law. After the child turns 21, the 10-year rule generally begins for the remaining inherited balance.

Inherited Roth and traditional IRAs can produce different income-tax results even when similar distribution deadlines apply. Qualified Roth distributions may be tax-free, while traditional IRA distributions are generally taxable to the extent they represent untaxed income. Beneficiaries should verify account-specific deadlines and tax treatment under current IRS guidance.

Penalties for missing inherited IRA RMDs

Enforcement matters in 2026. The IRS provided penalty relief for certain missed inherited-account RMDs for tax years 2021 through 2024, but that relief has ended. Beneficiaries subject to annual RMDs should not assume another waiver applies.

The excise tax for failing to withdraw a required amount is generally 25% of the shortfall. It may be reduced to 10% when the failure is corrected within the applicable two-year correction window. A beneficiary who discovers a missed distribution should contact a qualified tax professional promptly to determine the required withdrawal, correction procedure, tax filing, and whether reasonable-cause relief may be available.

Trust or estate

A properly drafted trust may be appropriate for a minor, a beneficiary with special needs, a blended family, or someone who should not receive unrestricted access to a large account. The IRA custodian may request the trust document or specified certifications. The trust must satisfy detailed federal requirements to receive certain beneficiary treatment.

Naming an estate can create additional administration and may reduce the distribution flexibility available when an individual is named directly. It should generally be a planned choice, not the unintended consequence of an incomplete designation.

HSA Beneficiaries Have Different Tax Consequences

An HSA may resemble another investment account, but its treatment after death depends heavily on whether the beneficiary is the account owner’s spouse.

If the beneficiary is the surviving spouse, the account generally becomes the spouse’s HSA. The spouse can continue using the account for qualified medical expenses under the applicable HSA rules.

If the beneficiary is not the spouse, the account generally stops being an HSA on the owner’s date of death. Its fair market value generally becomes taxable income to the beneficiary. If the estate is the beneficiary, the account value is generally included as income on the deceased owner’s final federal income-tax return.

The taxable amount for a non-spouse beneficiary may be reduced by qualified medical expenses incurred by the deceased owner and paid by the beneficiary within one year after death, provided the statutory requirements are satisfied. The beneficiary should retain invoices, explanations of benefits, and proof of payment.

Coordinate the HSA designation with the person likely to handle final medical expenses and with the broader estate plan. Because administrators use different forms and procedures, confirm whether the provider permits multiple beneficiaries, contingent beneficiaries, or trust designations.

Life Insurance and Retirement Accounts Should Tell the Same Story

Life insurance proceeds generally follow the policy’s beneficiary form and usually avoid probate when a valid living beneficiary is named. Proceeds are commonly received free of federal income tax, although interest, estate-tax issues, transfer-for-value rules, and other exceptions may require professional review.

Primary and contingent beneficiaries should reflect the purpose of the policy, which might include:

• Replacing income for a surviving spouse.
• Paying a mortgage or other household obligations.
• Funding education or childcare.
• Providing immediate liquidity while retirement accounts remain invested.
• Supporting children from a prior relationship.

Directly naming a minor can create legal and administrative problems because an insurer generally cannot make a large payment directly to a child. A custodial arrangement, court-appointed guardian, or properly drafted trust may be needed.

Direct payment to a beneficiary receiving means-tested public benefits may also disrupt eligibility. A special-needs trust may be appropriate, but it requires specialized legal drafting and an exact match between the trust’s legal name and the policy paperwork.

Naming a trust can provide control and protection, but the trust must be properly drafted, active when required, and correctly identified on the insurer’s form. Creating a trust without updating the policy designation may leave the intended plan incomplete.

Coordination does not require identical percentages on every asset. For example, a spouse might receive 100% of the life insurance to provide immediate cash for household expenses, while adult children receive designated shares of retirement assets. The combined plan can support the family’s goals without dividing every account the same way.

A 2026 Beneficiary Designation Audit Checklist

1. Build a complete inventory

List every asset that may transfer under a beneficiary or registration form:

• 401(k), 403(b), 457, Thrift Savings Plan, and other workplace plans
• Traditional, Roth, SEP, and SIMPLE IRAs
• HSAs
• Life insurance policies
• Pensions and annuities
• Payable-on-death bank accounts
• Transfer-on-death brokerage accounts and securities

2. Obtain current confirmations

Request the current beneficiary confirmation from every provider. Do not rely on memory, an old statement, or a copy of a form that may never have been accepted. Confirm that each designation is active in the provider’s records.

3. Check names, percentages, and instructions

• Primary beneficiary percentages total 100%.
• Contingent beneficiary percentages total 100%.
• Names match each beneficiary’s current legal identity.
• Addresses, dates of birth, and other identifying details are current.
• Deceased beneficiaries have been replaced where appropriate.
• Per stirpes or per capita instructions match the intended result.
• Any required spousal consent has been completed under the plan’s procedures.

4. Review after major life events

Recheck the forms after marriage, divorce, remarriage, birth, adoption, death, retirement, a job change, an account rollover, or a major revision to a will or trust. An updated will or divorce decree should not be treated as proof that every beneficiary form changed automatically.

5. Compare the forms with the full estate plan

Review beneficiary designations alongside the will, trust, powers of attorney, insurance coverage, and plans for final expenses. Evaluate the combined result rather than reviewing each account in isolation.

For example, confirm that the intended guardian or trustee can manage assets for a child, that enough liquid money will be available for immediate expenses, and that the beneficiary arrangement does not undermine planning for a family member with special needs.

6. Escalate complex situations

Consult qualified estate-planning and tax professionals before naming a trust, estate, minor child, or beneficiary with special needs. Professional review is also valuable for blended families, large estates, charitable gifts, creditor concerns, substantial retirement balances, and beneficiaries who live outside the United States.

What to Do Next

1. Complete an inventory of every account and policy with a beneficiary designation.
2. Download or request the current confirmation from each provider.
3. Correct missing beneficiaries, outdated names, and incomplete percentage allocations.
4. Store accepted confirmation records with your estate-planning documents.
5. Schedule an annual review and another review after every major life event.
6. Verify inherited-account deadlines, required distributions, and current 2026 tax rules before taking action.

The most effective beneficiary plan is not necessarily complicated. It is documented, current, and coordinated. A short annual review can prevent an old form from overriding years of otherwise careful estate planning—and can give beneficiaries clearer instructions when they need them most.
