Beneficiary Designations: Why They Can Override Your Will

Jonathan Leonard • October 16, 2026

Many people spend real time and money getting a will right, then forget about the beneficiary forms they filled out years ago when they opened a retirement account or bought life insurance. Those forms often matter more. For many accounts, whoever is named on the form receives the money, regardless of what your will says. Here's how beneficiary designations work and what's worth checking.

Key Takeaways

  • Retirement accounts, life insurance, and accounts with a transfer-on-death registration generally pass to the named beneficiary, not through your will.
  • An outdated form can send money to an ex-spouse, a deceased relative, or your estate instead of the people you intended.
  • In most employer retirement plans, your spouse must be your primary beneficiary unless they sign a written waiver.
  • Who you name affects how quickly heirs must withdraw inherited retirement money and the taxes they pay on it.
  • New Jersey's inheritance tax depends on the beneficiary's relationship to you: close family is exempt, while siblings and others can owe tax.

Why the Form Usually Wins

A beneficiary designation is a contract between you and the financial institution holding the account. When you die, the institution pays whoever is listed on the form on file. FINRA notes that a transfer-on-death or other beneficiary form supersedes your will, which is why it recommends making sure your designations conform to your estate plan.

The accounts this usually covers include IRAs, 401(k)s and 403(b)s, annuities, life insurance, and bank or brokerage accounts with a payable-on-death or transfer-on-death registration. For many retirees, those accounts hold most of their assets. A will that's perfectly up to date can end up controlling only a small part of what you leave behind.


The upside is that assets passing by beneficiary designation generally skip probate, the court process for settling an estate, so heirs can often receive them faster. The trade-off is that the form does exactly what it says, even when that's no longer what you'd want.

Common Mistakes Worth Checking

  • Never updating after a life change. Marriage, divorce, a death in the family, or a new grandchild are all reasons to review every form. A Department of Labor advisory council found that plans differ on whether a divorce automatically removes an ex-spouse as beneficiary, and noted that plans can generally rely on the form on file. (Source: dol.gov/sites/dolgov/files/ebsa/pdf_files/2012-current-challenges-and-best-practices-concerning-beneficiary-designations-in-retirement-and-life-insurance-plans.pdf, U.S. Department of Labor, ERISA Advisory Council report on beneficiary designations)
  • Leaving it blank. With no living beneficiary named, the account may go to your estate under the plan's default rules. That can mean probate, and for retirement accounts, less flexibility for heirs on withdrawals.
  • No contingent beneficiary. If your primary beneficiary dies before you and there's no backup listed, you're back to the plan's default.
  • Naming a minor directly. Financial institutions generally can't pay a large sum straight to a child, which can mean a court-supervised arrangement. A trust or custodial arrangement is often worth discussing with an estate attorney instead.
  • Assuming the will fixes it. Writing "my IRA goes to my children" in a will generally doesn't change who receives an IRA with a different name on the form.

Spouses and Employer Plans

Employer retirement plans have an extra rule. In many plans covered by federal law, your spouse is typically required to be your primary beneficiary unless they sign a waiver giving up that right. (Source: finra.org/investors/investing/investment-accounts/retirement-accounts, FINRA, Retirement Accounts) IRAs generally don't have the same federal requirement, so rolling a 401(k) into an IRA can change which rules apply. If you're remarried or have children from an earlier marriage, it's worth confirming what each plan requires before assuming your form says what you think it does.

How Your Choice Affects Your Heirs' Taxes

Who you name also affects how inherited retirement money is taxed. A surviving spouse generally has the most flexibility, including the option to treat an inherited IRA as their own. Most other beneficiaries who inherited after 2019 must empty the account within 10 years, and some must take withdrawals every year along the way. (Source: irs.gov/retirement-plans/plan-participant-employee/retirement-topics-beneficiary, IRS, Retirement Topics: Beneficiary) We cover those rules in more detail in our post on Required Minimum Distributions.


Withdrawals from an inherited traditional IRA are taxed as income to the beneficiary, so a large balance left to a child in their peak earning years can be taxed at a higher rate than it would be for someone in a lower bracket. That's one reason some families coordinate beneficiary choices with Roth conversion decisions, though a conversion carries its own upfront tax cost.

The New Jersey Piece

New Jersey no longer has an estate tax, but it still has an inheritance tax, and it depends on who receives the money. Spouses, civil union and domestic partners, children, stepchildren, parents, grandparents, and grandchildren (Class A) are exempt. Siblings and sons- or daughters-in-law (Class C) get a $25,000 exemption, then pay 11% to 16% on the rest. Most other people, including nieces, nephews, and friends (Class D), pay 15% on the first $700,000 and 16% above that. Charities are exempt.

That makes the name on a beneficiary form a state tax decision as well as a personal one. If you plan to leave money to a sibling, niece, nephew, or friend, it's worth understanding the inheritance tax before you finalize the form. Your estate planning attorney can explain how it applies to each type of account.

Where This Fits Into Your Bigger Retirement Picture

Beneficiary forms are some of the simplest documents in your financial life and some of the easiest to forget. A review takes an afternoon: list every account and policy, request the current designation from each institution, and compare them against your will and your wishes. It's a natural part of estate planning and worth repeating after any major life change.
