A retirement account beneficiary designation is the form on file with your plan or IRA custodian that names who inherits the account when you die, and it legally overrides whatever your will says. The person listed on that form gets the money, full stop. Getting the form right takes a few minutes; getting it wrong can route your savings to an ex-spouse, tie your family up in probate, or trigger a tax bill that a different choice would have avoided.
Who You Can Name
Most plans let you name almost anyone: a spouse, child, sibling, friend, domestic partner, or any other individual. You can also name a trust, which is useful when you want to control how the money is spent over time rather than handing over a lump sum. Charities are eligible too, and because qualified nonprofits don’t owe income tax on distributions, naming one can carry a tax advantage.
You can name your estate, but it’s almost always the wrong call. Estate-routed money goes through probate, which is public, slow, and exposed to creditor claims, and it can lose the more favorable payout timelines available to a named individual. Unless you have a specific reason to send the account through probate, name a person, trust, or charity directly.
One boundary worth flagging: if your intended beneficiary is a non-U.S. citizen living abroad, retirement distributions to foreign persons are generally subject to 30% federal income tax withholding unless a tax treaty between the U.S. and their country of residence provides a lower rate.1Internal Revenue Service. Plan Distributions to Foreign Persons Require Withholding
Primary and Contingent Beneficiaries
Every beneficiary form has two tiers. Primary beneficiaries are first in line. Contingent beneficiaries inherit only if every primary beneficiary has died before you or disclaims the money. Skipping the contingent line is a common mistake: if your primary beneficiary predeceases you and you never update the form, the account can default to your estate and land in probate anyway.
You can split each tier among multiple people by percentage. Three children at roughly 33% apiece is a typical setup. The percentages within each tier have to total exactly 100%, or the institution will reject the form. Unequal shares are allowed; nothing in the law requires beneficiaries to receive equal portions.
Most forms also ask you to choose between “per stirpes” and “per capita” for what happens if a named beneficiary dies before you. Per stirpes sends that person’s share down to their own children. If you named three children equally and one dies first, per stirpes routes that one-third to their kids rather than to your other two children. Per capita instead redistributes the deceased beneficiary’s share among the surviving beneficiaries at that tier. Forms default one way or the other; check yours and override the default if it doesn’t match what you want.
Spousal Consent Rules
Federal law treats employer plans and IRAs very differently here, and mixing them up is one of the most common ways beneficiary forms go wrong.
401(k), 403(b), and Pension Plans
For employer plans governed by ERISA, your surviving spouse is automatically entitled to the full account balance. To name anyone else as primary beneficiary, your spouse must sign a written waiver witnessed by a plan representative or a notary public.2U.S. Department of Labor. FAQs About Retirement Plans and ERISA The statute also requires the couple to have been married for at least one year before spousal protections apply.3Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans
If you submit a form naming a non-spouse beneficiary without a valid waiver, the plan administrator will override your designation and pay the spouse. This happens most often when someone fills out a form at a new job before getting married and never revisits it afterward.
Traditional, Roth, SEP, and SIMPLE IRAs
IRAs are not covered by ERISA, so there’s no federal requirement that your spouse consent to a non-spouse beneficiary. You can generally name whoever you want. The exception is the nine community property states, where your spouse has an ownership interest in IRA contributions made during the marriage and must waive that community property right before the IRA can pass entirely to someone else. Many IRA custodians in those states build a spousal consent line into the form for this reason.4Internal Revenue Service. Publication 555 – Community Property
After a Divorce
Divorce does not automatically strip your ex-spouse off your beneficiary form. The Supreme Court settled this in Kennedy v. Plan Administrator for DuPont, holding that an ERISA plan administrator’s job is to follow the beneficiary designation on file, not to interpret divorce decrees or waivers filed outside the plan’s own procedures.5Justia US Supreme Court. Kennedy v Plan Administrator for DuPont Savings and Investment Plan The participant in that case had a divorce decree in which his ex-spouse waived rights to his retirement account, but he never updated the form. The plan paid the ex-spouse the full balance, and the Court said the administrator did exactly what the law required.
Some plans include a provision that revokes designations upon divorce, but many large national plans don’t, because they have no reliable way to know whether a divorce has occurred.6U.S. Department of Labor. Current Challenges and Best Practices Concerning Beneficiary Designations in Retirement and Life Insurance Plans If you get divorced, update every retirement account beneficiary form yourself. Don’t assume the decree handles it.
If You Want to Leave the Account to a Minor
Naming a child under 18 directly creates a problem most parents don’t see coming. A minor can’t legally take ownership of an inherited IRA or accept a plan distribution, so a court typically has to appoint a guardian or conservator of the estate before the child gets anything. That means cost, delay, and a judge making decisions you could have made yourself.
Two cleaner options exist. The first is naming a custodian under the Uniform Transfers to Minors Act, which lets a named adult manage the money on the child’s behalf until they reach the age of majority under state law, without court involvement. You can set this up directly on most beneficiary forms. The second is naming a trust for the child’s benefit, which gives you more control over when and how the money gets distributed.
Minor children of the account holder also get favorable treatment on the payout side. They qualify as “eligible designated beneficiaries,” meaning the 10-year distribution clock doesn’t start until the child reaches the age of majority. After that, the standard 10-year drawdown period applies.7Internal Revenue Service. Retirement Topics – Beneficiary This applies only to the account holder’s own children, not grandchildren or other minor relatives.
How the Money Gets Paid Out and Taxed
The SECURE Act reshaped inherited retirement accounts. For account holders who die in 2020 or later, most non-spouse beneficiaries must empty the entire inherited account by the end of the tenth year following the year of death.7Internal Revenue Service. Retirement Topics – Beneficiary This replaced the older “stretch IRA” strategy that let beneficiaries take distributions over their own life expectancy.
Whether you have to take annual distributions during those 10 years depends on whether the original owner had already started their required minimum distributions before death. If they died before their RMD start date, you can distribute the account however you want inside the 10-year window. If they had already begun RMDs, you must take annual distributions in years one through nine based on the IRS life expectancy tables, and still empty the account by year 10.
Who Escapes the 10-Year Rule
Five categories of beneficiaries can still stretch distributions over their own life expectancy:7Internal Revenue Service. Retirement Topics – Beneficiary
- A surviving spouse, who can also roll the account into their own IRA or treat the inherited account as their own.
- A minor child of the account holder, exempt until reaching the age of majority.
- A disabled individual, as defined under the IRS disability rules.
- A chronically ill individual, as certified by a licensed health care practitioner.
- Any individual not more than 10 years younger than the account holder, which often covers siblings close in age or older friends.
Everyone else, including most adult children, falls under the 10-year rule.
Traditional vs. Roth Tax Treatment
Every dollar distributed from an inherited traditional IRA or pre-tax 401(k) is taxed as ordinary income in the year the beneficiary receives it. No capital gains treatment, no step-up in basis. Taking a large inherited traditional IRA as a lump sum can push the beneficiary into a much higher bracket, so spreading distributions across the 10-year window is often the better move.
Inherited Roth accounts are more forgiving. Withdrawals of contributions are always tax-free. Earnings are also tax-free if the original owner held the Roth for at least five years before death, measured from the beginning of the tax year of the first contribution.7Internal Revenue Service. Retirement Topics – Beneficiary If the Roth is younger than five years at the owner’s death, earnings the beneficiary withdraws may be taxable, though no early withdrawal penalty applies. The 10-year drawdown still applies to inherited Roths for non-spouse beneficiaries, but the tax-free nature of the distributions takes most of the pressure off the timing.
Filling Out and Submitting the Form
For each person you name, have their full legal name, Social Security number (or Taxpayer Identification Number for a trust or charity), date of birth, and current mailing address ready. Missing or inaccurate fields are the most common reason submissions get rejected. Most plan administrators offer the form through a secure online portal or through your employer’s HR department.
Digital forms usually validate as you go, flagging percentages that don’t total 100% or required fields left empty. For paper forms, print clearly in black ink and double-check Social Security numbers, since transposed digits create real problems at claim time. After you submit, confirm the updated designation appears on your next account statement. That confirmation is your proof the institution recorded your instructions.
Online portals timestamp submissions automatically. For paper forms, use certified mail or get a receipt from HR so you have proof of delivery.
When to Review What’s on File
A beneficiary form filled out at age 25 can quietly become a disaster if it never gets touched again. Certain events should trigger an immediate review:
- Marriage. Your new spouse gains automatic rights to ERISA-governed accounts, and you likely want to add them to your IRAs too.
- Divorce. As above, the form doesn’t update itself. You have to do it.
- Birth or adoption of a child. New children aren’t automatically added to existing designations.
- Death of a named beneficiary. If your primary dies and you don’t update the form, the assets pass to your contingent, or to your estate if you never named one.
- Remarriage. A new spouse has ERISA protections that may override existing designations on employer plans, but your IRA forms won’t update on their own.
Even without a major life change, reviewing your designations every two to three years catches small issues: an outdated address, a beneficiary you’d now prefer to replace, or a per stirpes election you didn’t realize was missing. The form takes minutes to update. Fixing the consequences of an outdated one can take years.
