Yes, you can name a trust as the beneficiary of your retirement account, like an IRA or 401(k). This move creates a direct conflict between your desire for ironclad control over your legacy and the challenging tax laws you must follow.
The core problem is a clash between your goals and federal tax law, specifically Internal Revenue Code Section 401(a)(9). This rule, radically changed by the SECURE Act of 2019, largely ended the “stretch IRA” and created a strict 10-year payout for most heirs. For many trusts drafted before 2020, this change created a devastating “tax trap” that can force a massive lump-sum payout, potentially erasing a huge chunk of the inheritance.
This is a major issue, as Americans held over $37 trillion in retirement accounts in 2023. A single error on a beneficiary designation form—a document that legally overrides your will—can cause irreversible financial damage to your family. This guide will break down everything you need to know into simple, actionable steps.

Deconstructing the Decision: The Players, the Asset, and the Tool
To figure out if naming a trust is the right move for you, you first need to understand the three key pieces of the puzzle.
The Key Players: Grantor, Trustee, and Beneficiary
Every trust has three main roles. While you might play all three roles at first in a simple plan, it’s vital to know how they differ.
The Grantor is you—the person who creates the trust and puts assets into it. You are the architect, working with an attorney to write the rulebook that says exactly how your money should be handled.
The Trustee is the manager you pick to follow your rulebook. This person or institution has a legal duty to manage the trust’s assets wisely and always act in the best interest of the beneficiaries.
The Beneficiary is the person or group the trust was created for. They are the ones who will ultimately get the money from the trust, according to the rules you, the Grantor, set up.
The Key Asset: The Retirement Account (and its Superpower)
Your IRA or 401(k) is a special kind of asset. It doesn’t pass to your heirs through your will. Instead, it goes to whomever you named on a simple document called a beneficiary designation form.
This form is a binding contract between you and the company holding your account. It is more powerful than your will. If your will leaves everything to your spouse, but your old IRA form names your sibling, your sibling gets the IRA.
The Key Tool: The Trust
A trust is like a detailed instruction manual for your money. It’s a legal container you create to hold assets for your beneficiaries. Instead of leaving money directly to a person, you leave it to the trust, and your trustee must follow your specific instructions.
The “See-Through” Trust: Your Golden Ticket to Tax Benefits
The IRS has one set of rules for human beneficiaries and another, much harsher set for non-human entities. A person is a “Designated Beneficiary” and can often get better tax treatment. An entity, like your estate or a poorly drafted trust, is a “Non-Designated Beneficiary” and gets hit with the worst payout rules, forcing a quick withdrawal and a huge tax bill.
Luckily, the IRS offers a critical exception. If your trust meets four strict tests, the IRS will “look through” the trust and treat your human beneficiaries as if you named them directly. This is called a “See-Through Trust,” and qualifying is the most important first step.
The Four Unbreakable IRS Rules for a See-Through Trust
Your trust must pass all four of these tests. Failing even one means it becomes a Non-Designated Beneficiary, and the worst tax rules apply.
- The Trust Must Be Valid Under State Law. This means your trust must be properly created according to the laws of your state. A do-it-yourself trust that misses a key state rule will fail this test immediately. The consequence is that the trust is treated as a Non-Designated Beneficiary, forcing a rapid and tax-heavy payout.
- The Trust Must Become Irrevocable at Your Death. A revocable trust, which you can change while you’re alive, must have language that automatically makes it unchangeable the moment you die. The IRS needs to know the rules are locked in. The consequence of failure is, again, the trust becomes a Non-Designated Beneficiary, triggering accelerated taxes.
- The Beneficiaries Must Be Identifiable Individuals. The trustee must be able to identify every possible person who could benefit from the trust, and they must all be human beings. If a non-individual, like a charity, is even a remote possibility to inherit the retirement funds, the entire trust can be disqualified. The consequence is losing see-through status and facing a massive tax bill.
- Proper Paperwork Must Be Sent to the IRA Custodian. Your trustee has a strict deadline: they must give the IRA custodian (like Fidelity or Schwab) a copy of the trust or a list of all beneficiaries by October 31st of the year after your death. Missing this deadline is unforgiving. Even with a perfect trust, failing to provide the paperwork on time makes it a Non-Designated Beneficiary.
A New World Order: How the SECURE Act Rewrote the Rules
Before 2020, the “stretch IRA” allowed a young heir to take small required minimum distributions (RMDs) over their entire lifetime, letting the account grow tax-deferred for decades. The Setting Every Community Up for Retirement Enhancement (SECURE) Act of 2019 completely changed this strategy.
The 10-Year Rule: A Ticking Clock for Your Heirs
For most people who are not a surviving spouse, the stretch IRA is gone. It has been replaced by the 10-Year Rule. This rule is simple: the entire inherited retirement account must be completely empty by the end of the 10th year after the original owner’s death. This forces a much faster payout, which can push heirs into higher tax brackets.
The VIP List: Who Are the “Eligible Designated Beneficiaries” (EDBs)?
The SECURE Act created a special protected class of heirs called Eligible Designated Beneficiaries (EDBs). These individuals are exempt from the 10-Year Rule and can still use a life expectancy payout, just like the old stretch IRA.
The five types of EDBs are:
- The Surviving Spouse
- Minor Children of the Account Owner (but not grandchildren)
- Disabled Individuals
- Chronically Ill Individuals
- Anyone Not More Than 10 Years Younger Than You
The Critical Choice: Conduit vs. Accumulation Trusts
After creating a see-through trust, you must decide how it will handle IRA withdrawals. This is a high-stakes choice between two main types: conduit and accumulation.
Conduit Trusts: The Simple (But Now Dangerous) Pass-Through
A conduit trust is like a simple pipe. The trust document legally forces the trustee to immediately pass any money withdrawn from the IRA directly to the beneficiary in the same year. The trustee cannot hold onto the funds.
The Conduit Trust “Tax Trap”: How a Good Plan Went Bad
The 10-Year Rule created a huge problem for many conduit trusts. The issue is that for many heirs, the 10-Year Rule does not require any withdrawals in years one through nine. The only rule is that the account must be empty by the end of year ten.
This creates a nightmare scenario. The conduit trust’s rules say it can only pass through required distributions. Since nothing is required for nine years, the trustee is forced to withdraw 100% of the IRA in year ten and immediately give that massive, taxable lump sum to the beneficiary, potentially pushing them into the highest tax bracket.
Accumulation Trusts: The Fortress of Control and Protection
An accumulation trust gives the trustee flexibility. The trustee can receive an IRA distribution and decide whether to pay it to the beneficiary or keep it inside the trust for future needs. This provides maximum control and protects the money from the beneficiary’s creditors, lawsuits, or a divorce.
The Accumulation Trust “Tax Bite”: The High Price of Control
This control has a steep cost: brutal tax rates. Any taxable income the trust keeps is taxed at compressed trust tax brackets. In 2025, a trust is projected to hit the top 37% federal tax rate after earning just over $15,000. A married couple might not hit that same rate until their income is over $700,000.
Tale of the Tape: Conduit vs. Accumulation After the SECURE Act
| Feature | Conduit Trust | Accumulation Trust | | :— | :— | | Distribution Mandate | All IRA withdrawals must be paid out to the beneficiary immediately. The trustee has no choice. | The trustee can choose to pay out withdrawals or keep them in the trust for later use. | | Asset Protection | Weak. Once the money is distributed, it is exposed to the beneficiary’s creditors and legal issues. | Strong. As long as the money stays in the trust, it is generally shielded from the beneficiary’s creditors. | | Post-SECURE Act Risk | EXTREMELY HIGH. Can become a “tax trap” under the 10-Year Rule, forcing a huge lump-sum payout in year 10. | More flexible, but any money kept in the trust is hit with very high tax rates, which can shrink the inheritance. | | Best Use Case | Now very limited. Mainly for an Eligible Designated Beneficiary (EDB) where a lifetime stretch is still possible. | Beneficiaries who need long-term protection (minors, spendthrifts, special needs) where control is the top priority. |
Real-World Blueprints: When a Trust Is the Unbeatable Choice
Here are three common situations where a trust is essential.
Scenario 1: The Modern Blended Family
Michael is in his second marriage to Susan and has two children from his first marriage. He wants to provide for Susan but also ensure his $2 million IRA eventually goes to his kids. If he names Susan directly, she gets full control and can leave the money to her own children, disinheriting Michael’s.
The Trust Solution: Michael creates an accumulation trust and names it as the IRA beneficiary.
| Provision in Trust | Outcome for Heirs |
| The trustee must pay all income from the trust to Susan for her lifetime. | Susan gets a steady income to live on, fulfilling Michael’s goal of supporting her. |
| The trust names Michael’s two children as the only people to receive the money after Susan’s death. | Michael’s children are guaranteed to inherit what’s left. Susan cannot change this. |
| The trust includes a spendthrift clause. | The money in the trust is protected from any of Susan’s potential creditors or lawsuits. |

Scenario 2: Protecting a Loved One with Special Needs
Maria has a son, David, who has a disability and relies on government benefits like SSI and Medicaid. These programs have strict asset limits, so a direct inheritance of Maria’s $500,000 401(k) would disqualify him from receiving essential support.
The Trust Solution: Maria works with an attorney to create a Third-Party Special Needs Trust (SNT) and names it as the 401(k) beneficiary.
| Planning Step | Benefit Preservation |
| Name the SNT as the beneficiary, not David directly. | The money is owned by the trust, not David. It doesn’t count against his asset limits, so his benefits are safe. |
| Draft the SNT as an accumulation trust. | The trustee can hold the money and use it for supplemental needs that benefits don’t cover, like therapy or a special van. |
| Ensure the trust qualifies for the EDB “stretch.” | Because David is disabled, he is an EDB. The trust can stretch the 401(k) payouts over his entire life, minimizing taxes. |
| Avoid the “Poison Pill.” | The attorney makes sure the trust has no language allowing a payout to a non-disabled person during David’s life, which would kill the stretch. |
Scenario 3: Guarding Against Youthful Indiscretion
Frank’s 22-year-old daughter, Emily, is not good with money. He wants to leave her his $750,000 IRA but fears she will spend it all quickly. If he names her directly, she gets total control and can withdraw everything at once.
The Trust Solution: Frank sets up an accumulation trust and names it as the IRA beneficiary.
| Distribution Strategy | Long-Term Result |
| The trustee is directed to give Emily the inheritance in stages: one-third at age 30, one-third at 35, and the final third at 40. | Emily is protected from her own financial immaturity. The inheritance is preserved for her long-term security. |
| The trust allows the trustee to pay for Emily’s health and education needs before the staged payouts. | Emily’s essential needs are covered, but her access to large sums of cash is controlled by a responsible trustee. |
| The trust includes strong asset protection language. | The money held in the trust is shielded from Emily’s potential creditors or a future divorce until it is paid out to her. |

Navigating the Minefield: Critical Mistakes to Avoid
- Mistake #1: Naming Your Estate as the Beneficiary. This is the worst choice. It forces the IRA into the public and expensive probate process and triggers the most punishing tax rules.
- Mistake #2: Forgetting the Spousal Rollover. A surviving spouse can roll an inherited IRA into their own, which is the best possible tax outcome. Naming a trust as the primary beneficiary forfeits this powerful option forever.
- Mistake #3: Using an Outdated Conduit Trust. A pre-SECURE Act conduit trust can become a tax trap, forcing a massive lump-sum payout in year 10 that decimates the inheritance.
- Mistake #4: The Accidental Charity Remainder. Naming a charity as a backup beneficiary within your trust can disqualify it from see-through status, forcing a rapid and tax-heavy payout.
- Mistake #5: Failing to Update Beneficiaries. Life events like divorce or death change everything. An old beneficiary form could send your entire IRA to an ex-spouse, no matter what your will says.
Your Strategic Checklist: The Do’s and Don’ts of Naming a Trust
| Do’s | Don’ts |
| ✅ DO hire an experienced estate planning attorney. (Why: This is too complex for a DIY approach; the risks are too high). | ❌ DON’T name your estate as a beneficiary. (Why: It guarantees probate and the worst possible tax outcome). |
| ✅ DO name your spouse as the primary beneficiary. (Why: This preserves the incredibly valuable spousal rollover option). | ❌ DON’T assume your will controls your IRA. (Why: The beneficiary designation form is legally superior and will win). |
| ✅ DO review your beneficiary forms every 3-5 years. (Why: Life changes can make old plans obsolete and cause huge problems). | ❌ DON’T use a pre-2020 conduit trust without a legal review. (Why: It is likely a “tax trap” waiting to happen under the SECURE Act). |
| ✅ DO confirm your trust meets all four “see-through” rules. (Why: Failing even one rule leads to harsh tax penalties). | ❌ DON’T name a charity as a remainder beneficiary without expert advice. (Why: It can disqualify the entire trust from favorable tax treatment). |
| ✅ DO choose your trustee very carefully. (Why: This person or company is responsible for carrying out your exact wishes). | ❌ DON’T forget to name contingent (backup) beneficiaries. (Why: If your primary heir is gone, your IRA could default to your estate). |

Weighing Your Options: The Pros and Cons of Using a Trust
| Pros | Cons |
| 👍 Ultimate Control: You can set the rules for how the inheritance is used for decades, protecting it from bad decisions or outside threats. | 👎 High Cost & Complexity: A properly drafted trust is expensive to set up, and a professional trustee will charge ongoing management fees. |
| 👍 Powerful Asset Protection: Money held in a trust is shielded from a beneficiary’s creditors, lawsuits, and divorce settlements. | 👎 Loss of Spousal Rollover: Naming a trust as the primary beneficiary prevents a surviving spouse from using their best and most tax-friendly option. |
| 👍 Solves Blended Family Issues: It’s the perfect tool for second marriages, letting you provide for a new spouse while ensuring your kids inherit the rest. | 👎 Punishing Tax Rates: Income kept inside an accumulation trust is taxed at the highest federal rates on very small amounts of money. |
| 👍 Essential for Special Needs Planning: It’s the only way to provide for a disabled loved one without kicking them off vital government benefits. | 👎 Administrative Headaches: The trustee has major legal and tax reporting duties that are complex and time-consuming. |
| 👍 Protects Minor Children: It avoids a public court guardianship and lets you decide when a young heir is mature enough to receive their inheritance. | 👎 Potentially Faster Payouts: If the trust has multiple beneficiaries, the payout schedule is based on the oldest person’s age, which can speed up taxes for younger heirs. |
From Blueprint to Reality: A 4-Step Guide to Implementation
Step 1: Assemble Your Professional Team This is not a solo project. You need a coordinated team of an estate planning attorney, a CPA or tax advisor, and a financial advisor to get this right.
Step 2: Draft the Trust Document Work with your attorney to create the trust. This is where you’ll decide who will be the trustee, who the beneficiaries are, and whether it will be a conduit or accumulation trust.
Step 3: Complete the Beneficiary Designation Form After the trust is signed, you must update the beneficiary designation form with your IRA custodian. You must name the trust precisely, for example: “The Trustee of the Jane Smith Revocable Trust, dated March 15, 2025”.
Step 4: The Trustee’s Post-Death Duties After your death, the trustee must notify the IRA custodian and provide the required trust documents before the critical October 31st deadline. They will then work to set up the inherited IRA and begin managing distributions according to your rules.
The Local Angle: Why State Law Still Matters
While federal tax law sets the rules for IRA distributions, the trust itself is a legal entity created under your state’s laws. The very first IRS rule is that the trust must be valid under state law. This is why working with a qualified attorney in your state is absolutely essential.
Frequently Asked Questions (FAQs)
- Can my spouse still do a spousal rollover if a trust is the beneficiary? No. The spousal rollover is only available if the spouse is named directly on the IRA form. Naming a trust, even one for the spouse’s sole benefit, forfeits this powerful option.
- Are the rules different for a Roth IRA versus a Traditional IRA? Yes. The distribution rules are the same, but the tax treatment is different. Qualified withdrawals from an inherited Roth IRA are completely tax-free, while Traditional IRA withdrawals are taxed as ordinary income.
- Is a trust worth the cost for a small IRA? No, probably not. For smaller IRAs, the legal and administrative fees can eat up a large part of the inheritance, making simpler options a better choice.
- What happens if I name my minor grandchild as a direct beneficiary? Yes, this causes problems. A court must appoint a guardian to manage the money, which is public and costly. The child then gets the entire amount as a lump sum at age 18 or 21.
- Should I review my beneficiary designations regularly? Yes. You should review them every 3-5 years and after any major life event like a marriage, divorce, or death. An outdated form can cause your legacy to go to the wrong person.
