Do IRA and 401(k) Beneficiaries Override My Will?

Do beneficiary designations on an IRA or 401(k) override my will?

For the account itself, the beneficiary form carries the practical instruction. The IRS says an account owner may generally select a person or entity to receive IRA or retirement-plan benefits, subject to the plan's procedures and restrictions. A will does not supply the retirement plan's beneficiary form.

Workplace-plan rules add a second layer. The U.S. Department of Labor states that, in most defined-contribution plans, a surviving spouse automatically receives benefits when a participant dies before receiving them. A married participant who names another beneficiary generally needs the spouse's signed waiver, witnessed by a notary or plan representative.

The same account-by-account discipline belongs outside retirement plans. The SEC's Investor.gov explains that a transfer-on-death registration sends securities directly to the named person or entity without probate. That direct path is why a will alone is not a complete audit.

Keep the audit narrow and factual: account name, institution, current primary beneficiary, current contingent beneficiary, and date the form was last confirmed. A family change can alter the facts faster than paperwork changes.

Who should I name as the contingent beneficiary on my retirement accounts?

A contingent beneficiary is the named backup when the primary beneficiary cannot receive the account. The form creates a sequence. Leaving the second line blank leaves the outcome to the custodian agreement and plan rules rather than to a stated backup choice.

The right name depends on the account owner's family structure, estate documents, and the plan's limits. The IRS says a beneficiary may generally be any person or entity the owner selects, while also noting that qualified-plan distribution options are set by the plan document. Read the Summary Plan Description for a workplace plan before treating two forms as interchangeable.

Review triggers are plain: marriage, divorce, remarriage, a birth, a death, and a new job. The Labor Department specifically tells participants who marry after enrollment to notify the employer or plan administrator and change plan status. Forms age quietly.

A contingent designation is also a useful cross-check against related plans. A household preparing for a move can face similar record mismatches across assets; the same habit of checking terms before signing appears in this guide to reviewing a rent-to-own home agreement. Names, dates, and governing documents decide more than memory does.

Should I name my trust as the beneficiary of my IRA?

A trust can be named, but it can complicate the inherited-IRA analysis. The IRS Publication 590-B for 2025 says a trust cannot itself be a designated beneficiary for required minimum distribution purposes. Its beneficiaries can be treated as designated beneficiaries only when the trust is valid under state law, becomes irrevocable at death, has identifiable beneficiaries, and required documentation reaches the IRA custodian.

That is not a clerical detail. The IRS notes that multiple beneficiaries or a trust can change the distribution analysis. A trust designation calls for review of the trust language, the IRA agreement, the people who benefit under the trust, and the custodian's documentation requirements before the form is signed.

The ten-year rule raises the stakes. Under IRS guidance for deaths after 2019, a designated beneficiary who is not an eligible designated beneficiary generally must distribute the entire IRA by December 31 of the year containing the tenth anniversary of death. An owner who dies in 2025 creates a deadline of December 31, 2035, according to Publication 590-B for 2025.

Eligible designated beneficiaries have different treatment under the IRS rules. They include a surviving spouse, the owner's minor child, a disabled individual, a chronically ill individual, and a person no more than 10 years younger than the owner. A trust does not erase those categories; it makes identifying the relevant beneficiary analysis more demanding.

Taxable inherited-account distributions are included in gross income, according to the IRS beneficiary guidance. The named recipient and the route through a trust can therefore affect both control of the assets and the distribution framework. A trust is a legal tool, not a shortcut.
