Beneficiary Designations: The Estate Planning Documents Most People Forget
A 401(k) form filled out on your first day at a startup can override a carefully drafted will. Here is why beneficiary designations deserve a regular review.
Most people think of an estate plan as a will or a trust. In practice, a large share of a Silicon Valley household's wealth passes outside both. Retirement accounts, life insurance, and many brokerage and bank accounts transfer according to the beneficiary form on file with the institution, regardless of what a will says. For a tech professional who has changed employers, rolled over accounts, married, or had children, those forms may be years out of date.
Which assets pass by designation
A 401(k), IRA, Roth IRA, health savings account, and employer life insurance policy each carry a beneficiary designation. Brokerage and bank accounts can carry transfer-on-death or payable-on-death instructions that work the same way. California also allows a revocable transfer on death deed for a home, which must be signed before two witnesses, notarized, and recorded within 60 days, and which has no effect if the property is held in joint tenancy or community property with right of survivorship and the other owner survives.
These assets bypass probate and are not governed by your will. If the designation is blank or names someone who has died, the account usually falls to the plan's default rules or to your estate, which can mean a court process and, for retirement accounts, a less favorable payout schedule.
Why the tax rules make this matter more for retirement accounts
Since the SECURE Act, most non-spouse beneficiaries of an IRA or 401(k) must empty the account by the end of the tenth year after the owner's death, according to the IRS beneficiary guidance. Every dollar withdrawn from a pre-tax account is taxable income to the beneficiary. A surviving spouse has more flexibility, including rolling the account into their own IRA, and eligible designated beneficiaries such as minor children, disabled or chronically ill individuals, and people not more than ten years younger than the owner can stretch distributions longer.
The practical consequence is that who you name changes the tax outcome. Naming an adult child in peak earning years compresses a large pre-tax balance into a decade of high-bracket income, especially in California, which taxes ordinary income at rates up to 13.3%. Naming a trust can preserve control over how and when a beneficiary receives money, but a trust not drafted to qualify as a "see-through" trust may face worse treatment. Naming a charity for pre-tax dollars, while leaving Roth and taxable assets to family, is one approach some households consider because a charity pays no income tax.
Common mistakes
A few patterns show up repeatedly.
An ex-spouse remains the named beneficiary on a 401(k) from a prior employer, and federal law governing employer plans may honor that form even after a divorce.
A new parent never adds contingent beneficiaries, so if both spouses die together the account passes through the estate.
A minor child is named directly, which generally requires a court-appointed guardian and hands the money over outright at 18.
A living trust is created but the accounts still name individuals, so the trust's provisions never apply to the largest assets.
Each can be fixed in minutes once identified, which is why an annual review is worthwhile.
Coordinating with the rest of the plan
Beneficiary forms and estate documents should tell a consistent story. If a trust is meant to hold assets for young children, the contingent beneficiary on retirement accounts should usually be that trust, drafted with retirement account rules in mind. For married couples, a 401(k) generally must name the spouse as primary beneficiary unless the spouse consents in writing, a rule that does not apply to IRAs. Community property principles in California may also give a spouse an interest in an account regardless of the form.
Equity compensation adds one more layer. Unvested RSUs and options are governed by the plan document, which may not allow transfer at death, and vested shares held at a plan administrator may need their own designation or transfer-on-death instruction.
A short checklist
Gather every account statement and confirm the primary and contingent beneficiaries on each, along with current names and percentages. Check that designations line up with your will or trust, and revisit them after any marriage, divorce, birth, death, or job change. Keep copies with your estate documents so your executor or trustee can find them.
