How to Update Beneficiaries on Retirement Accounts in 2026
⏱ 12 min read · 2,348 words
If you haven't checked the beneficiary forms on your IRA, 401(k), or pension in the last five years, there's a real chance the wrong person will inherit your money. Not because of a will that needs updating. Not because of probate delays. Because a beneficiary designation you filled out 20 years ago maybe when you first got hired, maybe when you opened your first IRA still sits on file somewhere. And that form overrides everything else.
I've sat across the table from people who remarried in their 60s and assumed their new spouse would automatically inherit their retirement accounts. They're wrong. Many advisors have seen adult children discover their father's second wife someone they barely knew inherited his entire 401(k) because he never changed the form after his divorce was finalized. That's not a mistake you can fix after the fact.
This article walks through exactly how to update beneficiaries on retirement accounts in 2026, which forms you need, and what happens if you skip this step. It's a 20-minute task that most people put off until it's too late.
Why Most People Don't Update Their Beneficiaries Until Something Goes Wrong
Retirement account beneficiary forms feel like paperwork you fill out once and forget. The problem is that life doesn't work that way. You get divorced. You remarry. Your adult child gets married and you want to split the account between them and your new daughter-in-law. A sibling you named as a backup beneficiary passes away before you do.
Most financial advisors will tell you to review beneficiaries every few years. That's good advice. But almost no one does it. Why? Because nothing forces you to. There's no annual reminder. No expiration date. The form just sits in a file at your plan provider until someone asks for it after you die.
Here's what makes this harder: beneficiary rules are different for IRAs, 401(k)s, pensions, and annuities. Some accounts let you update online. Others require a notarized signature on a paper form mailed to an office in another state. If you have three retirement accounts, you might need three different processes.
How to Update Beneficiaries on Retirement Accounts. Step by Step
The exact process depends on who holds your account. But the basic steps are the same across most providers.
Step 1: Log in to your account online. Most large providers. Fidelity, Vanguard, Schwab, TIAA let you update beneficiaries directly through their website. Look for a section called "Beneficiaries," "Estate Planning," or "Account Settings." If you can update online, do it. It's faster and you'll get instant confirmation that the change went through.
Step 2: If online updates aren't available, request the form. Some older 401(k) plans and pension systems still require paper forms. Call your plan's customer service number or download the form from their website. The form is usually called a "Beneficiary Designation Form" or "Change of Beneficiary Form."
Step 3: Fill out the form completely. You'll need each beneficiary's full legal name, Social Security number, date of birth, and relationship to you. If you're naming multiple beneficiaries, assign a percentage to each. The total must add up to 100%. If one beneficiary dies before you do and you haven't updated the form, their share typically goes to your other named beneficiaries not to their heirs. Plan for that possibility by naming contingent (backup) beneficiaries.
Step 4: Get the form notarized if required. Some plans require notarization. Some don't. The form will tell you. If you need a notary, most banks offer free notary services to account holders. UPS stores and some public libraries also have notaries available for a small fee.
Step 5: Mail or upload the form and confirm receipt. If you're mailing a paper form, send it via certified mail with tracking. Follow up two weeks later to confirm the provider received it and processed the change. Ask for written confirmation. Keep a copy of the updated form in your files at home.
What Happens If You Don't Update After a Divorce
Divorce decrees don't automatically update your retirement account beneficiaries. This point cannot be emphasized enough this enough. Your divorce might say your ex-spouse gets nothing. Your will might leave everything to your kids. None of that matters if your ex-spouse is still listed as the beneficiary on your 401(k) form.
Federal law protects spousal rights to certain retirement accounts. If you're legally married when you die, your spouse is entitled to at least 50% of your 401(k) or pension unless they signed a waiver. But once you're divorced, that protection ends and whoever is on the form inherits the account.
Take someone who worked 30 years in municipal government, earning around $58,000 a year toward the end of his career. He got divorced at 62, two years before he retired. His divorce decree clearly stated his ex-wife would receive half the marital home and a portion of his pension but nothing from his deferred compensation account. He died at 68, never having updated the beneficiary form on that account. His ex-wife inherited the full $240,000 balance. His adult daughter got nothing. The courts upheld the beneficiary designation.
This is how to split an IRA in divorce after retirement: you don't split it by updating a will or relying on a divorce decree. You update the beneficiary form immediately after the divorce is finalized. That's the only document that matters.
Naming a Trust vs. Naming Individuals
You can name a trust as the beneficiary of your retirement accounts. Some estate planning attorneys recommend this if you want more control over how the money is distributed after you die. For example, you might want the money doled out in installments to a child who's bad with money, or you might want to protect the inheritance from a beneficiary's creditors.
But naming a trust has tax consequences. If the trust isn't set up correctly, your heirs might lose the ability to stretch IRA distributions over their lifetime. Since the SECURE Act passed in 2019, most non-spouse beneficiaries have to empty an inherited IRA within 10 years anyway. But trusts add complexity and legal fees. For most people in their 60s and 70s, naming individuals as beneficiaries is simpler and gives your heirs more flexibility.
If you're considering a trust, talk to an estate attorney who understands the SECURE Act rules. Don't name a trust as beneficiary just because someone told you it's "more sophisticated." It might cost your heirs more in taxes than it saves in probate fees.
What You Might Not Know About Contingent Beneficiaries
Most people fill out the "Primary Beneficiary" section and stop there. They skip the "Contingent Beneficiary" section entirely. That's a mistake.
Contingent beneficiaries inherit your account if all your primary beneficiaries die before you do. If you don't name contingent beneficiaries and your primary beneficiaries are gone, the account typically goes to your estate. That triggers probate, which means delays, legal fees, and less control over who gets what.
Name at least one contingent beneficiary. If you're naming your spouse as primary, name your adult children as contingent. If you're naming multiple children as primary, name your grandchildren or a charity as contingent. Think through what happens if everyone on the first line is gone.
How Inflation Affects Fixed-Income Retirees and Why This Matters
If you're living on a pension or annuity that doesn't adjust for inflation, your purchasing power erodes every year. That's how inflation affects fixed-income retirees. You might be tempted to leave a smaller percentage of your IRA to family and convert more of it into a guaranteed income stream for yourself.
One option is a qualified longevity annuity contract, or QLAC. A QLAC is a deferred annuity you buy with IRA or 401(k) dollars. You give the insurance company a lump sum now, and they start paying you a guaranteed monthly income at age 80 or 85. QLACs reduce your required minimum distributions because the money you put into the QLAC doesn't count toward your RMD calculation.
The catch: once you buy a QLAC, that money is locked in. You can't change your mind and leave it to your kids instead. Some QLACs offer a death benefit if you die before payments start, but many don't. If protecting an inheritance is important to you, a QLAC might not fit your goals. This is another reason to think carefully about beneficiary designations before you convert IRA dollars into annuities.
When to Review Your Beneficiary Forms (and How Often)
Review your beneficiaries every time one of these happens:
- You get married or divorced: Update within 30 days. Don't wait.
- A beneficiary dies: Even if they were listed as secondary, remove them and update your contingent list.
- You have a child or grandchild: Decide now whether you want them included. Don't leave it ambiguous.
- You retire and roll a 401(k) into an IRA: The beneficiary designation doesn't transfer automatically. You fill out a new form when you open the IRA.
- You turn 73 and start RMDs: This is a natural time to review everything. Once you're taking required minimum distributions, it's worth confirming your beneficiaries are still correct.
If none of those apply, review beneficiaries every three to five years. Set a calendar reminder for your birthday. It takes 20 minutes.
What Happens If You Never Update Your Beneficiaries
If you die without a valid beneficiary on file, your retirement account goes to your estate. Your estate goes through probate. Probate is public, slow, and expensive. It also means your account might not go where you intended.
Your will might say your IRA goes to your daughter. But if your IRA beneficiary form is blank or invalid, the IRA follows your state's intestacy laws instead. In most states, that means your spouse gets everything if you're married. If you're not married, it goes to your children equally even if you wanted to leave different amounts to different kids.
Probate also delays access to the money. Instead of your beneficiaries receiving the funds within a few weeks, they might wait six months to a year while the estate is settled. During that time, the account continues to generate taxable income, but no one can touch it.
This is avoidable. Fill out the form.
Why You Should Keep a Copy of Your Beneficiary Forms at Home
Financial institutions lose paperwork. Mergers happen. Systems get updated and old records don't transfer cleanly. Many advisors have seen cases where a plan provider had no record of a beneficiary form on file, even though the account holder swore they mailed it in years ago.
When you update a beneficiary form, keep a copy in a file at home. Mark it clearly: "IRA Beneficiary. Updated March 2026." Store it with your other estate documents. Tell your executor or power of attorney where the file is. If there's ever a dispute about who was named, your copy is evidence.
Also keep a list of every retirement account you own, the account numbers, and the name of the institution. Your heirs can't claim an account they don't know exists.
Updating Your Beneficiaries Is Not the Same as Updating Your Will
Most people assume their will controls everything they own. It doesn't. Retirement accounts, life insurance policies, and payable-on-death bank accounts all pass directly to the named beneficiaries. They bypass your will entirely.
You can write in your will that your IRA goes to your son. But if your daughter is listed as the beneficiary on the IRA form, your daughter gets the money. The will doesn't override the form. The form is the binding document.
If you update your will, update your beneficiary forms at the same time. Make sure they're consistent. If they conflict, the beneficiary form wins every time.
Closing Thoughts
Updating beneficiaries on your retirement accounts is one of the simplest estate planning tasks you can do, and it's also one of the most commonly skipped. The form you filled out 20 years ago might still be on file, even if everything in your life has changed since then.
Check your accounts this month. Log in online if you can, or call your plan provider and request the current beneficiary information. If anything is outdated or wrong, fix it now. If you've never named a contingent beneficiary, add one. If you got divorced and never updated the form, do it today.
This isn't about probate law or estate taxes. It's about making sure the people you want to inherit your retirement savings actually get it. Twenty minutes now prevents years of legal disputes later.
Frequently Asked Questions
Q: Can I name a minor child as the beneficiary of my IRA?
A: Yes, but the money will be managed by a court-appointed guardian until the child turns 18 (or 21 in some states). If you want more control, consider naming a trust as beneficiary instead, with instructions for how the money should be used. Otherwise, your 18-year-old could inherit $300,000 with no restrictions.
Q: What happens if I name multiple beneficiaries but don't assign percentages?
A: Most plan providers will split the account equally among all named beneficiaries. If you want an unequal split, you must specify percentages. If you write "50% to my son, remainder to my daughter," and your son dies before you, your daughter typically inherits 100% not 50%.
Q: Do I need to update beneficiaries on my pension if I'm already receiving monthly payments?
A: It depends on the pension payout option you chose when you retired. If you selected a single-life annuity, payments stop when you die and there's no beneficiary. If you chose a joint-and-survivor option, your named survivor continues receiving payments. You usually can't change that election after retirement starts.
Q: Will my spouse automatically inherit my 401(k) even if I name someone else?
A: Under federal law (ERISA), your spouse has rights to your 401(k) or pension unless they sign a written waiver. Even if you name your adult child as beneficiary, your spouse can claim at least 50% of the account. IRAs don't have the same rule you can name anyone as beneficiary without spousal consent.
Q: How long does it take for a beneficiary to receive the money after I die?
A: If the beneficiary form is current and complete, most plan providers release funds within 2 to 6 weeks after receiving a certified death certificate and completed claim forms. If there's a dispute, missing paperwork, or the account goes to your estate, it can take 6 months to a year.
