Yes, retirement accounts can be placed in a trust, but the rules are complicated and mistakes can cost your family tens of thousands of dollars. Under federal tax law, when you name a trust as the beneficiary of an IRA or 401(k), different distribution requirements kick in that determine how fast your heirs must withdraw the money and pay taxes on it. A recent study found that over 60% of people with retirement accounts do not have proper beneficiary designations in place, leaving their estates vulnerable to unnecessary taxes and family conflict.

Understanding Retirement Accounts and Trusts: The Core Issue
Retirement accounts like IRAs and 401(k)s are special under federal law. The Internal Revenue Code Section 401 and related provisions created rules that allow you to delay paying taxes on your money while it grows inside these accounts. However, these same rules require that when money leaves the account—either during your life or after death—it must follow strict withdrawal timelines.
When you name a person as the beneficiary directly, the rules are straightforward. But when you name a trust instead, the IRS imposes additional requirements that treat the trust and its beneficiaries as the account holder. The problem is that trusts do not die like people do—they can last for decades or even generations—and the IRS uses this fact to determine how fast money must come out of the account.
The governing statute that creates this problem is the Employee Retirement Income Security Act (ERISA), which controls how retirement benefits must be distributed. When a trust owns a retirement account, ERISA rules interact with state trust law to create complexity that trips up families and advisors alike.
The Relationship Between Retirement Accounts, Trusts, and Tax Law
Retirement accounts come in several types, and each type has different rules about who can be the beneficiary and how distributions work. IRAs (Individual Retirement Accounts) include Traditional IRAs, Roth IRAs, SEP IRAs, and SIMPLE IRAs. Then there are employer-sponsored plans like 401(k)s, 403(b)s, and pension plans.
Trusts also come in different types. A revocable living trust lets you change it while you are alive, but it becomes irrevocable (locked) after you die. An irrevocable trust cannot be changed once created, even by the person who made it. Some trusts are “see-through” trusts that allow the IRS to look at who will eventually receive the money, while others are not.
The key relationship works like this: when you name a trust as beneficiary of a retirement account, the trust becomes the legal owner of the benefits. This means the trust’s terms—not the account’s original rules—control how money gets distributed. Under the SECURE Act passed in 2019, the distribution rules changed drastically for most beneficiaries who inherit retirement accounts after 2019. If a trust is the beneficiary, the type of trust matters enormously in determining whether your heirs get the money slowly over their lifetimes or must take it all out within ten years.
Why People Put Retirement Accounts in Trusts
Most people do not put the entire retirement account itself into a trust. Instead, they name the trust as the beneficiary of the account, which is different. The account stays in its normal form at the bank or investment firm, but the trust receives the money when the account owner dies. This approach preserves the tax benefits of the retirement account while giving the trust control over how the money is used after death.
People choose this path for several important reasons. First, it provides control over money for heirs who cannot be trusted to manage large sums—such as young children, spendthrift adults, or people with addictions. Second, it can provide protection from creditors in some situations, because the trust controls the money rather than the individual. Third, it can help manage taxes by spreading withdrawals across multiple years instead of forcing heirs to take everything at once.
A trust can also help coordinate money from multiple sources. For example, if someone dies with a $500,000 IRA, a house worth $300,000, and $100,000 in savings, a trust can manage all these assets together and make distributions according to a single plan. Without a trust, the IRA might go to one beneficiary, the house to another, and the savings to a third, creating unequal outcomes and family disputes.
The Three Most Popular Scenarios and What Happens
Scenario One: Using a See-Through Trust to Control Distributions to Spendthrift Heirs
Sarah is 55 years old and has a $400,000 traditional IRA. She has two adult children: Michael, who is financially responsible, and Jennifer, who has struggled with debt and has been sued by creditors twice. Sarah wants to leave money to both but fears Jennifer will spend it all immediately and lose everything in lawsuits. She decides to name a see-through trust as the beneficiary of her IRA, with instructions that distributions go to each child based on their needs, not a 50-50 split.
| What Happens | The Result |
|---|---|
| Sarah names the trust as IRA beneficiary | The trust becomes the legal owner of IRA proceeds when Sarah dies |
| Trustee receives the $400,000 when Sarah dies | The trustee must start taking distributions based on Jennifer’s life expectancy |
| Trustee distributes only what Jennifer needs each year | Jennifer gets money for her needs but the bulk stays protected in the trust |
| Any money left in trust is protected from Jennifer’s creditors | Creditors cannot touch what remains because Jennifer does not directly own it |
The key advantage here is that Sarah’s trust terms override the default rule that would give all the money directly to Jennifer as soon as Sarah dies. Under IRS regulations for see-through trusts, if the trust names Jennifer as the beneficiary, the IRS will calculate the required distribution based on Jennifer’s life expectancy—potentially 40+ years. This stretches out the tax payments and lets the account continue growing tax-free on the undistributed balance.
Scenario Two: The Second Marriage Situation Where a Trust Protects the Original Family
Robert, age 62, has $600,000 in a 401(k) from his career as an engineer. He was married to Michelle for 30 years but divorced five years ago. He recently married Karen and wants to leave money for Karen’s security but ensure that any remaining balance eventually goes to his adult children from his first marriage. Without a trust, he would have to choose: either leave everything to Karen (risking that his children get nothing) or leave everything to his children (leaving Karen with no support).
| Decision | What Happens Next |
|---|---|
| Robert names Karen as sole 401(k) beneficiary | Karen inherits the full $600,000 and can do anything with it; children get nothing |
| Robert names his children as 401(k) beneficiaries | Karen has no claim; she must be supported from other assets if any exist |
| Robert names his trust as 401(k) beneficiary | The trust can distribute to Karen for life, then to his children after her death |
In the third scenario, the trust acts as a coordinator between competing interests. The trust terms specify that Karen receives income from the account during her lifetime—perhaps $20,000 per year—while the principal stays protected. After Karen dies, the remaining balance passes to Robert’s children. This solves the problem without forcing Robert to choose between his current wife and his original family.
Scenario Three: Using an Irrevocable Life Insurance Trust (ILIT) to Fund a Retirement Account Replacement
David, age 50, realizes his retirement accounts may not be enough to leave his family in secure financial condition. He also wants to minimize estate taxes, which become a problem when someone’s total assets exceed $13.61 million (as of 2024). He creates an irrevocable life insurance trust and has the trust own a $2 million life insurance policy on his life. The policy will pay $2 million to the trust when David dies, and the trust terms allow the trustee to use this money to purchase David’s retirement accounts from his estate.
| Step in the Process | What This Accomplishes |
|---|---|
| Irrevocable trust is created and owns the life insurance | The $2 million policy death benefit is not taxed as part of David’s estate |
| Policy pays the trust $2 million when David dies | The trust has cash available to buy retirement accounts from the estate |
| Trust purchases the IRA or 401(k) from the estate | The retirement account’s value is funded from insurance proceeds, not taxable |
| Heirs inherit the account but with less estate tax impact | The distribution is stretched over many years based on trust terms |
This strategy works because the death benefit of a life insurance policy owned by an irrevocable trust is excluded from the taxable estate, while a policy owned by the individual is included. By having the trust own the policy, David removes the insurance proceeds from taxation, creating more money for his family.
The SECURE Act Changed Everything
On January 1, 2020, the SECURE Act fundamentally changed how retirement account beneficiaries must withdraw money. Before this law, beneficiaries could stretch withdrawals over their entire lifetimes—potentially 50+ years. After the SECURE Act, most non-spouse beneficiaries must withdraw the entire account within 10 years, even if they are much younger than the account owner.
This change hit trusts particularly hard. If a trust is the beneficiary, the trust does not have a “life expectancy” in the way a person does. The IRS must therefore look at the oldest beneficiary whose name appears in the trust document, which often means a much shorter withdrawal window than the old law allowed.
SECURE 2.0 Act (2022) added more complexity by creating exceptions for certain types of trusts. If a trust is designed specifically to work with retirement accounts and meets strict technical requirements, called a “Designated Beneficiary Trust” (DBT), the trustee might qualify for better distribution rules. However, most existing trusts do not meet these requirements and must use the 10-year withdrawal rule instead.
How Different Trusts Affect Distribution Rules
See-Through Trusts and the “Look-Through” Rule
A see-through trust (also called a conduit trust) is named for the IRS’s ability to “see through” the trust to the actual people who benefit from it. When calculating how fast distributions must happen, the IRS looks at the oldest beneficiary named in the trust and uses that person’s age to determine the withdrawal timeline.
Imagine a trust that benefits both a 35-year-old daughter and a 70-year-old father. The IRS uses the father’s age (oldest), not the daughter’s age, to calculate required distributions. This means the account must be distributed faster than if the daughter were the sole beneficiary. The advantage of this trust type is that only the current beneficiaries matter for the calculation—charitable organizations or future beneficiaries do not count.
Accumulation Trusts and the Compressed Tax Rate Problem
An accumulation trust is designed to hold money inside the trust rather than distributing it all to beneficiaries every year. The trust receives distributions from the retirement account and can decide to keep some money invested and growing inside the trust. This sounds advantageous, but accumulation trusts face a serious tax disadvantage: trust income is taxed at higher tax rates than individual income.
In 2024, a trust reaches the top federal income tax bracket (37%) when its income exceeds $14,600. An individual does not reach the top bracket until income exceeds $578,100. This means that if a trust holds retirement account distributions instead of passing them through to beneficiaries, the money gets taxed at punitive rates. For example, $100,000 in distributions to an accumulation trust could result in $37,000 in federal taxes, whereas the same $100,000 distributed to an individual beneficiary might result in only $24,000 in taxes depending on that person’s other income.
Conduit Trusts and the Catch-Up Advantage
A conduit trust takes the opposite approach: it must distribute to beneficiaries any money it receives from the retirement account. This requirement sounds restrictive, but it creates a tax advantage. By passing money through to the beneficiary rather than keeping it in the trust, the conduit trust avoids the compressed tax rate problem.
However, conduit trusts have their own limitation under SECURE 2.0: they no longer stretch distributions over the beneficiary’s lifetime as the old law allowed. Instead, the beneficiary must take the full amount within 10 years. The advantage of a conduit trust is that it forces money out to beneficiaries rather than accumulating inside the trust at high tax rates.
Irrevocable Trusts and the Income Tax Trap
An irrevocable trust cannot be changed once created, not even by the person who made it. This permanence is powerful for asset protection—if creditors cannot touch the money, it is truly protected. However, irrevocable trusts that are beneficiaries of retirement accounts face severe tax complications.
When an irrevocable trust receives distributions from a retirement account and does not pass the money through to individual beneficiaries, the trust must pay income tax at the trust’s rates, not the beneficiary’s rates. In many cases, this results in double taxation: once at the trust level when the money is distributed from the retirement account, and again when the trustee eventually distributes it to the beneficiary. Some irrevocable trusts are designed to avoid this by including “conduit” language that forces distributions to beneficiaries, but not all do.
Special Needs Trusts and the Preserve-Benefits Strategy
A special needs trust (SNT) is designed for a beneficiary with disabilities who receives government benefits like SSI (Supplemental Security Income) or Medicaid. If this person inherits money directly, the inheritance might disqualify them from these benefits, leaving them worse off financially. A special needs trust can be the beneficiary of a retirement account, and the trustee can use distributions for the beneficiary’s needs while preserving their government benefits.
The key rule is that the trustee must spend distributions for the beneficiary’s health, education, maintenance, and support, but cannot pay for things government benefits already cover. For example, the trustee can pay for dental work (not covered by Medicaid), but should not pay for basic medical care (covered by Medicaid). This requires careful management, but it allows a person with disabilities to inherit an IRA or 401(k) without losing crucial government support.
How to Name a Trust as Beneficiary
Naming a trust as the beneficiary of a retirement account requires specific steps, and details matter enormously. The account custodian (the bank, brokerage, or insurance company holding the account) has its own forms and rules, and they often have different requirements than the IRS does.
The first step is to contact the custodian and request the official beneficiary designation form for that specific account. Do not use a generic form from the internet or from your trust document. Each custodian has slightly different requirements, and using the wrong form can result in the beneficiary designation being rejected or interpreted incorrectly.
On the form, the beneficiary section should be filled out exactly like this: “The [Name] Trust dated [Date of Trust Creation], as amended.” Do not use “my trust” or “family trust” unless that is the formal name. The custodian needs the exact legal name and creation date so they can verify the trust actually exists and identify which version of the trust document they are looking at if there are amendments.
Many custodians require a copy of the trust document to process the beneficiary designation. The IRS allows custodians to ask for this, and most major custodians do require it. Provide a certified copy if possible, or at least an official copy from your attorney. Some custodians only require what is called a “Certificate of Trust,” which is a shorter document that certifies the trust exists and includes the trust’s authority provisions without exposing the full trust document (which may contain personal information about other beneficiaries).
After submitting the form and trust document, the custodian will typically confirm receipt and process the change. Keep a copy of the confirmation for your records. Many people make the mistake of assuming the change went through without getting written confirmation, then their family later discovers the beneficiary designation was never actually changed.
Critical IRS Requirements for See-Through Trusts
For a trust to be treated as a “see-through” trust by the IRS, the trust document must meet specific requirements outlined in IRS Regulation 1.401(a)(9)-4. If the trust does not meet these requirements, the trust is treated as a non-see-through trust, which triggers much faster distribution rules.
The first requirement is that the trust must be valid under state law. This sounds obvious, but it means the trust must be properly created and executed according to the laws of the state where the account owner lives or where the trust is governed. A trust created in one state might not be valid in another state. Many trusts are governed by the laws of the state where they are created, but you should verify this with your attorney.
The second requirement is that the trust must be irrevocable or will become irrevocable at the death of the account owner. A revocable living trust automatically becomes irrevocable when the person dies, so this requirement is satisfied. However, some other trusts allow the person who created them to keep the ability to change them even after death (through their estate), which fails this requirement.
The third requirement is that the beneficiaries of the trust must be identifiable. The IRS must be able to determine who will receive distributions from the retirement account and in what order. A trust that says “distribute to my children in whatever amounts the trustee decides” might fail this test because the IRS cannot determine the precise order of who will actually receive money. The trust should specify which children, in what percentages or amounts, and when they receive distributions.
The fourth requirement is that the trust document must require that all retirement account distributions be paid to the trust. Some trusts are drafted to allow the account owner to change their mind and have distributions paid directly to individual beneficiaries instead of to the trust. If the trust allows this flexibility, it fails the see-through requirements. The trust must be mandatory—distributions must go to the trust, not elsewhere.
Mistakes to Avoid When Placing Retirement Accounts in Trusts
Mistake #1: Naming a Non-See-Through Trust
The single most common mistake is naming a trust as beneficiary without ensuring the trust meets the see-through requirements. If the trust does not qualify, the IRS treats the trust itself as the beneficiary, not the people inside it. Since a trust has no life expectancy, the required distribution timeline is calculated based on the life expectancy of the oldest beneficiary, and in many cases, this forces faster withdrawals than needed.
The consequence is that heirs must withdraw more money per year, accelerating income taxes. If a trust is structured poorly, the full account balance might be required to be withdrawn within 5-10 years instead of being stretched over 30+ years. This can mean an extra $50,000 to $200,000 in taxes depending on the account size and the beneficiaries’ tax brackets.
Mistake #2: Failing to Update the Trust After SECURE 2.0
Many trusts were created before 2022 and do not include the language needed to qualify as a “Designated Beneficiary Trust” under SECURE 2.0. These old trusts may not work as the owner intended. For example, a trust created in 2015 with a goal of stretching distributions over a beneficiary’s lifetime now gets the 10-year rule instead because it does not have DBT language.
The consequence is that the retirement account must be fully distributed within 10 years, even if the beneficiary is young, rather than over their lifetime. Updating the trust document to add DBT language can restore the stretch-out benefit. However, some trusts cannot be updated because of irrevocable provisions, which means the original goal cannot be achieved.
Mistake #3: Including Charitable Beneficiaries in a See-Through Trust
Some people want to benefit charity along with their family members, so they create a trust that names both their children and their favorite charity as beneficiaries. However, including a charity disqualifies the trust from being a see-through trust because a charity has no life expectancy. The IRS must calculate the required distributions based on the oldest human beneficiary, which often causes faster withdrawals.
The consequence is that the family must withdraw the account faster, accelerating income taxes. A better approach is to name individual family members as the trust beneficiaries and handle charitable giving separately through a different mechanism, such as naming the charity directly as a beneficiary of a small portion of the account or using the Qualified Charitable Distribution rules (available for individuals age 70½ and older).
Mistake #4: Not Providing the Trust Document to the Custodian
Many people create a trust, name it as the retirement account beneficiary on the form, and assume they are done. However, the custodian needs a copy of the trust document to verify the trust meets IRS requirements. If no copy is provided, the custodian might treat the trust as non-see-through and use the default (faster) distribution rules.
The consequence is that when the account owner dies, the heirs discover the trust was not properly recognized, and they must take distributions faster than intended. By the time they realize the mistake, it is too late to fix it. The solution is simple: always provide a copy of the trust document to the custodian when naming the trust as beneficiary, and keep written confirmation that it was received and approved.
Mistake #5: Creating a Trust That Conflicts With Spousal Rollover Rights
If the account owner is married, the spouse has special rights under federal law. The spouse can roll over the entire retirement account into their own IRA, treating it as if they always owned it. This gives the spouse complete control and flexibility. However, if the beneficiary designation names a trust instead of the spouse, the spouse loses this right.
The consequence is that the spouse cannot roll over the account, and instead must take distributions according to the trust terms. If the trust requires all money to be distributed within 5 years, the spouse cannot prevent this and may face a large tax bill. Many financial advisors recommend naming the spouse directly as the primary beneficiary of at least a portion of the account and using a trust as the secondary (contingent) beneficiary, which preserves the spouse’s rollover option.
Mistake #6: Using Outdated Trust Language That Does Not Meet Current IRS Standards
Trust documents created before 2020 often contain language that does not align with current IRS standards. For example, an old trust might say “distribute to my children in equal shares” without specifying their names, ages, or order. The current IRS requirements are stricter about beneficiary identification, and an old trust might not survive IRS scrutiny.
The consequence is that the trust might not be recognized as a see-through trust, forcing the family to use faster distribution rules. Updating the trust document to include current language is relatively inexpensive compared to the tax cost of using the wrong distribution rules. Many attorneys recommend having trusts reviewed every 3-5 years to ensure they comply with current law.
Do’s and Don’ts When Using Trusts With Retirement Accounts
Do’s
Do name your spouse as the primary beneficiary if you are married. The spouse has unique privileges, including the right to roll over the account into their own IRA and inherit the spouse’s longer life expectancy for calculations. This is almost always the most flexible and tax-efficient option for married couples.
Do use a see-through trust as a secondary (contingent) beneficiary. If your spouse survives you but you want to protect money for your children, name your spouse as primary beneficiary and the trust as contingent. This preserves the spouse’s flexibility if needed while protecting money for your children if both of you pass away together.
Do ensure the trust document includes all names and identifies all beneficiaries clearly. The IRS must be able to determine exactly who will receive money and when. Vague language like “my heirs” or “my descendants” can cause the trust to lose see-through status.
Do provide a copy of the trust document to the custodian. Do not assume the custodian will accept the beneficiary designation without reviewing the trust. Getting written confirmation that the custodian received and approved the trust document prevents problems later.
Do review the trust document and beneficiary designations every 3-5 years. Tax law changes frequently, and a trust created 10 years ago might not meet current requirements. Regular reviews catch problems before they become expensive mistakes.
Don’ts
Don’t name your revocable living trust as the beneficiary of your entire retirement account. While a revocable living trust is convenient for other assets (avoiding probate on your house, for example), it creates unnecessary tax complexity for retirement accounts. The trust will not be recognized as see-through if it does not meet specific IRS requirements, and most basic revocable living trusts do not meet them without special language.
Don’t include multiple generations in the trust without considering the tax consequences. If the trust benefits both adult children and grandchildren, the IRS uses the oldest beneficiary’s age to calculate distributions. This forces withdrawals faster than if only the adult children were beneficiaries. Consider separate trusts for different generations.
Don’t assume the trust designation will work the same way as naming an individual beneficiary. The rules for trusts are different—distribution timelines are different, tax treatment is different, and the planning opportunities are different. Working with an attorney who understands retirement account trusts is worth the investment.
Don’t name your trust as beneficiary without making sure it will be irrevocable at your death. If your trust can still be changed after you die (which some complex trusts allow), it will not qualify as a see-through trust. Check your trust document carefully.
Don’t forget to consider state law requirements. Trusts are governed by state law where they are created, and some states have specific requirements about how trusts can own retirement benefits. Make sure your trust complies with your state’s laws.
Pros and Cons of Using a Trust as Retirement Account Beneficiary
| Pros | Cons |
|---|---|
| Provides control over distributions to heirs who cannot manage money responsibly | Distributions may be faster than if beneficiary inherited directly under SECURE Act rules |
| Protects money from creditors or lawsuits involving the heir | Trust must meet strict IRS requirements or distributions accelerate significantly |
| Allows you to benefit multiple family members under one plan rather than choosing between them | Tax rates in trusts are compressed, potentially resulting in higher taxes on accumulated distributions |
| Enables you to provide for heirs with special needs while protecting government benefits | Requires additional legal fees to create and maintain a proper trust document |
| Can reduce estate taxes if structured as an irrevocable trust | Requires naming a trustee who must manage the account and file tax returns for the trust |
| Allows you to manage multiple assets (retirement accounts, real estate, investments) under one coordinated plan | May conflict with spouse’s rights to roll over the account and treat it as their own |
| Can prevent unintended disinheritance in blended family situations | Adds complexity to the beneficiary designation process with custodians |
Special Situations and Exceptions
Inherited IRAs After SECURE Act Requires New Planning
Before 2020, when a beneficiary inherited an IRA, they could set up an “inherited IRA” in their own name and stretch distributions over their lifetime—potentially 50+ years. The SECURE Act ended this for most non-spouse beneficiaries. Now, most beneficiaries must withdraw the entire inherited account within 10 years.
However, certain “eligible designated beneficiaries” still get the stretch option. These include the spouse of the account owner, children under age 18 (until they reach 18), disabled individuals, chronically ill individuals, and beneficiaries who are less than 10 years younger than the account owner. If a trust is the beneficiary and the trust names one of these eligible designated beneficiaries, that person’s status might carry through to the trust, but this depends on how the trust is drafted.
Spousal Inherited IRAs and the Rollover Strategy
When a spouse inherits an IRA, they have a choice that no other beneficiary has. The spouse can roll over the inherited IRA into their own IRA, treating it as if they always owned it. Alternatively, the spouse can keep it as an inherited IRA and take distributions as required.
If the beneficiary designation names a trust and the spouse is the trust beneficiary, the spouse typically cannot do a rollover because the IRA is payable to the trust, not to the spouse directly. However, if the trust is drafted to allow the trustee to distribute the entire IRA to the spouse immediately, the spouse could then roll it over themselves. This requires careful planning and should be discussed with both the attorney drafting the trust and the financial advisor managing the account.
Non-Spouse Beneficiaries and the 10-Year Rule
Under SECURE 2.0, non-spouse beneficiaries who are not eligible designated beneficiaries must withdraw the entire account by the end of the 10th year following the account owner’s death. If a trust is the beneficiary and the trust names these individuals, the 10-year rule applies.
Some trusts are drafted with what is called a “conduit” structure, where distributions must be passed through to individual beneficiaries each year. Others use an “accumulation” structure, where the trustee can decide how much to distribute and how much to keep in the trust. Under the 10-year rule, both structures must ensure the account is fully distributed within 10 years, regardless of whether money flows to beneficiaries or stays in the trust.
Qualified Charitable Distributions and Estate Tax Deductions
People age 70½ and older can make Qualified Charitable Distributions (QCDs) directly from their IRA to a charity without paying income tax on the distribution. This rule is available under IRC Section 408(d)(8). However, if the beneficiary designation names a trust or any non-charitable beneficiary, the account owner cannot use the QCD option because the IRA is not being distributed to the owner themselves.
If charitable giving is important, the account owner should consider naming the charity directly as a beneficiary of a portion of the account or using the QCD option during their lifetime instead of planning for charitable distributions after death through a trust.
Special Needs Trusts, Irrevocable Life Insurance Trusts, and Other Advanced Structures
Special Needs Trusts (SNT) for Disabled Beneficiaries
A special needs trust can be an excellent beneficiary of a retirement account when the potential heir has disabilities. The disabled beneficiary does not own the money directly, so inheriting an IRA does not disqualify them from Medicaid, SSI, or other government benefits. The trustee must use distributions for the beneficiary’s health, education, maintenance, and support—but not for things government benefits already cover.
For example, if a parent has a child with cerebral palsy and wants to leave them money, a special needs trust can be the IRA beneficiary. The trustee can use distributions for physical therapy, specialized equipment, care attendants, or vacations—none of which affect the child’s government benefits. This is much better than leaving the account directly to the child, which would immediately disqualify them from benefits.
The challenge with special needs trusts is that the trustee must carefully track what government benefits cover and what they do not. Paying for something government benefits should have covered can disqualify the beneficiary from those benefits for extended periods. It is advisable to have the trustee work with a special needs planning attorney to ensure proper distributions.
Irrevocable Life Insurance Trusts (ILITs)
An irrevocable life insurance trust owns a life insurance policy on the account owner’s life. When the account owner dies, the policy pays death benefits to the trust. The trust can then use this money to purchase retirement accounts from the estate, pay estate taxes, or make distributions to beneficiaries.
The advantage of an ILIT is that the life insurance death benefit is not subject to estate tax because the trust owns the policy, not the individual. This allows the family to have much more money available after death compared to if the policy were owned by the individual. However, ILIT structures are complex and have strict requirements. The trust must be irrevocable, and the account owner must have no incidents of ownership in the policy.
Because the ILIT is irrevocable, it cannot be changed if laws change or family circumstances change. It also requires the account owner to fund it with cash gifts (to pay policy premiums), which counts against their lifetime gift tax exemption. For these reasons, ILITs are typically used only for wealthy families with large estates and complex planning needs.
Qualified Personal Residence Trusts (QPRT) and Other Advanced Trusts
A qualified personal residence trust allows the account owner to freeze the value of their home for estate tax purposes while retaining the right to live in the house for a specified period. When the period ends, the house passes to beneficiaries at a reduced tax value. QPRTs are powerful tax planning tools but are not typically used as retirement account beneficiaries because they serve a different purpose (reducing estate taxes on real estate).
However, some complex estate plans use multiple trusts working together. One trust might be the retirement account beneficiary, another might hold the house, and another might hold life insurance. A qualified estate planning attorney can design a coordinated structure that works together to minimize taxes and achieve the family’s goals.
The Tax Implications of Different Trust Structures
Income Tax Rates for Trusts Versus Individuals
Trust income is taxed at federal rates that are much steeper than individual rates. In 2024, a trust reaches the maximum federal income tax rate of 37% when taxable income exceeds $14,600. In contrast, an individual does not reach 37% until income exceeds $578,100. This means that if a trust receives retirement account distributions and does not pass them through to beneficiaries, the trust pays significantly more in taxes.
For example, suppose a trust receives $50,000 in distributions from a retirement account in a year. If the trust keeps this money (accumulation trust structure), the trust might owe approximately $18,500 in federal taxes on the $50,000 (37% of the amount over approximately $14,600). If the same $50,000 were distributed to an individual beneficiary in the 24% tax bracket, they would owe approximately $12,000 in taxes. The difference of $6,500 is a direct cost of using an accumulation trust instead of distributing to beneficiaries.
This is why many estate planning attorneys recommend using a “conduit” trust structure for retirement accounts. A conduit trust must distribute to beneficiaries any money it receives from the retirement account, allowing the beneficiary’s personal tax rate to apply instead of the trust’s rate. The downside is that the beneficiary receives the money and can spend it, which removes the protection the trust was meant to provide.
State Income Taxes and Trust Situs
The location of a trust (its “situs”) can affect state income taxes. Some states have no income tax, while others have high income taxes that apply to trust income. Many high-income individuals place trusts in states with no income tax to minimize the total tax burden.
However, moving a trust to a low-tax state is not as simple as just changing the trustee’s location. The state where the account owner lives, the state where the trust document is signed, and the state where the trustee is located all matter. Additionally, many states now have laws that tax trusts if the account owner or any beneficiary is a resident of that state, regardless of where the trust is legally situs.
If using a trust for retirement accounts and trying to minimize taxes, this is an advanced planning point worth discussing with a CPA or tax attorney who understands both trust law and tax law in your specific state.
Estate Tax Considerations and Wealth Preservation
Federal Estate Taxes and the Lifetime Exemption
The federal government taxes large estates when someone dies. In 2024, the first $13.61 million of an estate is exempt from federal estate tax, but amounts above that are taxed at 40%. For married couples, the exemption can be doubled to approximately $27.22 million if the trust is properly structured to use both spouses’ exemptions.
Retirement accounts are included in this calculation. If someone dies with a $10 million IRA and their estate total is $15 million, the $1.39 million over the federal exemption is subject to 40% estate tax, resulting in $556,000 in taxes. Using a trust to transfer the account to a beneficiary does not reduce estate taxes because the account is still included in the taxable estate. However, using an irrevocable trust created during the account owner’s lifetime might exclude the account from the taxable estate if properly structured.
Portability and Married Couples
Married couples can use a strategy called “portability” to effectively double the federal estate tax exemption. When the first spouse dies, the surviving spouse can elect to carry over (port) the unused exemption of the deceased spouse, increasing their own exemption from $13.61 million to approximately $27.22 million.
To use portability, the executor of the deceased spouse’s estate must file an estate tax return (Form 706) even if no estate tax is due. Many people fail to do this because they do not realize it is necessary, and once the deadline passes, the exemption is lost forever. Working with an estate planning attorney and CPA ensures that portability is properly elected if the family’s estate is large enough to benefit from it.
The Step-Up in Basis Strategy
When someone inherits an asset, the basis is “stepped up” to the asset’s value on the date of death. For example, if someone buys a stock for $10,000 and it grows to $50,000 when they die, the heir inherits it with a basis of $50,000. If the heir sells it immediately for $50,000, there is no capital gains tax. This is a powerful tax benefit.
However, retirement accounts like IRAs and 401(k)s do not receive a step-up in basis. When an heir inherits a $500,000 IRA, they inherit the full $500,000 in pre-tax income owed to the IRS. The IRA does not get a fresh start; the full amount is taxable when distributed. Using a trust does not change this rule. Some wealthy individuals use life insurance trusts to create cash that beneficiaries can use to pay the income taxes on inherited retirement accounts, preserving more of the retirement account for the heirs.
How Custodians Handle Trust Beneficiary Designations
What Custodians Need and Why
When a trust is named as the retirement account beneficiary, the custodian (bank, brokerage, insurance company) has a legal responsibility to verify that the trust qualifies as a see-through trust. The custodian can request documentation to confirm the trust meets IRS requirements. Different custodians have different policies, but most major custodians will ask for either a full copy of the trust document or a Certificate of Trust.
The Certificate of Trust is a shorter document that proves the trust exists and includes key information like the trustee’s name and authority, but does not include the full trust terms (which might be sensitive). Many attorneys prepare a Certificate of Trust specifically for this purpose. If the custodian asks for the full trust document, provide it—the custodian is required to keep it confidential.
Common Custodian Issues and Solutions
Some custodians have outdated systems that do not handle trust beneficiary designations smoothly. When attempting to name a trust as a beneficiary, the system might insist on an individual’s Social Security number when the beneficiary is a trust (trusts use EINs instead). This can cause the designation to be rejected or processed incorrectly.
If this happens, contact the custodian’s beneficiary department directly instead of trying to complete the form online or by mail. Explain that the beneficiary is a trust and ask what documentation they need. Many custodians have special procedures for trust beneficiaries even if their online system does not allow it. Persistence and clear communication often resolve these issues.
After submitting a trust beneficiary designation, always follow up in writing to confirm it was processed correctly. Some custodians are slow to process changes, and a written follow-up creates a paper trail. Request written confirmation of the change, and if the custodian cannot provide it immediately, ask for an estimate of when the change will be complete.
Updating Beneficiary Designations When Laws Change
When SECURE 2.0 was passed in 2022, many people realized their trust beneficiary designations no longer worked as intended. If the trust was created before 2022 and does not include “Designated Beneficiary Trust” language, the 10-year distribution rule applies instead of the old stretch-out rule.
To update the beneficiary designation, contact the custodian and request a new beneficiary form. Some custodians allow you to simply update the existing form, while others require a completely new form. File the updated form with a copy of any amended trust documents if the trustee or terms have changed.
Some custodians keep outdated records in their system, so periodically (every few years) verify that the current beneficiary designation matches your intention. You can request a printout of the beneficiary designation on file and compare it to your trust document and attorney’s records. If anything is inconsistent, file a new form to update it.
Real-World Examples: How Trusts Work in Different Situations
Example 1: Simple Trust for Spendthrift Protection
Maria is 60 years old and has three adult children, each with different financial sophistication. Carlos is a financial advisor, Elena is a teacher, and Juan has struggled with impulse spending. Maria has $300,000 in her traditional IRA and wants to provide equally for all three but is concerned Juan will waste his inheritance.
Maria creates a revocable living trust and includes specific language about retirement account distributions. She names the trust as the IRA beneficiary. The trust specifies that the trustee (her brother Ricardo) will distribute to each child according to their needs: Carlos and Elena receive their distributions in a lump sum (or several large payments), while Juan’s distribution is limited to $500 per month plus additional amounts for emergencies approved by the trustee.
When Maria dies, Ricardo receives the $300,000 in the trust. He can invest the money and manage it according to the trust terms. Carlos and Elena each receive approximately $100,000 over 1-2 years. Juan receives $500 per month for life (projected to be 30+ years), with his share of the account continuing to grow inside the trust. If Juan needs a new car, the trustee can approve an additional $15,000 distribution, but the trustee will not approve a distribution for luxury vacation spending.
The tax result depends on how the trust is drafted. If it is a conduit trust that requires distributions to be passed through to the children each year, Elena and Carlos would pay taxes on their distributions at their personal tax rates (roughly 22-24%). Juan would pay taxes on his monthly distribution (roughly $120 per month), keeping more money in the trust. If it is an accumulation trust, the undistributed portions staying in trust would face the higher trust tax rates, reducing the ultimate value.
Example 2: Blended Family Protection Through a Trust
Robert is 62 and has been married to Angela for 8 years. He has two adult children from a previous marriage (David age 35, and Lisa age 32). Robert has a $600,000 401(k) and wants Angela to be secure but also wants to ensure his children ultimately inherit something.
Robert creates a qualified terminable interest property (QTIP) trust that he names as the 401(k) beneficiary. The trust terms specify that Angela receives all income and principal distributions during her life, but when Angela dies, the remaining balance passes to David and Lisa.
When Robert dies, the trustee receives the $600,000. The trustee (Angela or a professional trustee) receives enough distributions from the account to provide Angela with her income while the principal grows. The account might generate $20,000-$30,000 per year in earnings, and the trustee distributes this to Angela. When Angela dies (projected 25 years later), the remaining balance—potentially $1 million or more—passes to David and Lisa.
The tax consequences are complex. The QTIP trust includes the full $600,000 in Robert’s taxable estate at death. However, if the amount is within Robert’s federal estate tax exemption ($13.61 million in 2024), no estate tax is owed. The account must still distribute to the trust according to the IRS timeline (10-year rule under SECURE 2.0), but the trustee can distribute this to Angela or keep it in the trust depending on the trust terms.
Example 3: Special Needs Trust for a Child With a Disability
Tom and Susan have three children: Michael age 28, Jennifer age 26, and David age 24 who has autism and receives SSI and Medicaid. Tom has a $400,000 Roth IRA and wants to provide equally for all three children but is concerned that leaving David money directly will disqualify him from government benefits.
Tom and Susan work with an attorney to create a special needs trust for David and name it as the IRA beneficiary. The trust specifies that distributions are for David’s “health, education, maintenance, and support” but cannot reduce or replace government benefits.
When Tom dies, the trustee receives the Roth IRA. The trustee distributes from David’s share to pay for his needs: $100 per month for David to spend on entertainment, $500 per month for a care attendant (not covered by Medicaid), $5,000 per year for dental work and other needs, and keeps the rest invested for long-term growth.
David’s SSI payment (approximately $900 per month) continues unchanged. David’s Medicaid continues unchanged. Because the trust owns the money, not David directly, his government benefits are protected. Michael and Jennifer receive their distributions directly or through their own trust arrangements.
The Roth IRA has a special advantage here. Roth IRAs do not require distributions during the owner’s lifetime, and distributions to heirs from a Roth IRA are income-tax-free if the account was open for at least five years. This means the trustee can take distributions to pay David’s care without worrying about income taxes, and the balance can continue growing tax-free inside the Roth IRA for decades.
Frequently Asked Questions
Can I put my 401(k) directly into a trust?
No. Your 401(k) employer plan does not allow this. You can name a trust as the beneficiary of the account, but the account itself stays at your employer or with the plan custodian. Upon your death, the trust receives the benefits.
What happens if I die without naming a trust as beneficiary?
No. If no beneficiary is named, the account passes to your estate by default. Your estate must go through probate, and the account money is distributed according to your will or state law. Probate is slow and public. Money likely goes to whoever your will specifies, regardless of their spending habits or financial responsibility.
Does a trust as beneficiary reduce estate taxes?
No. The account is still included in your taxable estate for federal estate tax purposes. However, a trust can reduce income taxes by allowing controlled distributions instead of forcing all money out at once into a high tax bracket.
Can my spouse still roll over the account if a trust is the beneficiary?
No. If the trust is the beneficiary, your spouse cannot do a rollover. Your spouse can only take distributions according to the trust terms. Consider naming your spouse directly as primary beneficiary and a trust as contingent beneficiary instead.
Do I need a special trust for retirement accounts?
No. Any trust can be a retirement account beneficiary if it meets IRS see-through requirements. However, trusts designed specifically for retirement accounts include language that helps avoid common mistakes.
What is a “see-through” trust?
Yes, it exists. A see-through trust meets IRS requirements so the agency can identify the actual beneficiaries and calculate correct distribution timelines. Without see-through status, distribution rules accelerate, costing extra taxes.
What is the difference between a conduit and accumulation trust?
No specific difference in whether they work, but they work differently. A conduit trust must distribute all retirement account distributions to beneficiaries immediately. An accumulation trust can keep money inside the trust. Conduit trusts have tax advantages; accumulation trusts provide more control.
Will my trust be recognized as see-through by the custodian?
It depends on whether your trust meets IRS requirements and whether you provide the trust document to the custodian. Always submit a trust document or Certificate of Trust when naming the trust as beneficiary.
Can I change the trust beneficiary designation later?
Yes. You can change the beneficiary designation on a trust anytime during your life by contacting the custodian and filing a new form. After your death, the beneficiary designation is locked in.
What should the beneficiary designation say exactly?
Include the trust’s exact legal name and date. Use this format: “The [Trust Name] Trust dated [Date], as amended.” Do not use vague language like “my trust” or “family trust.”
If my trust is irrevocable, can a trust still be a beneficiary?
Yes. Irrevocable trusts can be retirement account beneficiaries. However, irrevocable trusts cannot be changed later, and they may have different tax consequences than revocable trusts.
What is a Designated Beneficiary Trust under SECURE 2.0?
It is a trust designed to meet strict IRS requirements under the SECURE 2.0 Act. If your trust qualifies, certain beneficiaries might get better distribution timelines than under the regular 10-year rule.
Does the trust need an EIN (employer identification number)?
Yes, after the account owner dies. During the account owner’s life, the trust uses the owner’s Social Security number. After death, the trustee must obtain an EIN from the IRS to file tax returns for the trust.
What if the trust document says “distribute everything now”?
The account must distribute within the timeline specified by law, not by the trust. The trust cannot speed up distributions; it can only slow them down (or control how money is distributed to beneficiaries). IRS rules determine the minimum distribution speed.
Can a trust inherit both Roth and traditional IRAs?
Yes. A trust can be the beneficiary of multiple retirement accounts. However, track each account separately for IRS reporting. Roth and traditional accounts have different tax rules even if the same trust is the beneficiary.
If I have a living trust that avoids probate on my house, should I name it as IRA beneficiary too?
Not necessarily. Revocable living trusts created to avoid probate might not meet IRS see-through requirements for retirement accounts. Consult your attorney about whether your specific trust qualifies. If not, using a separate trust for the IRA is better.
What happens if the trust beneficiary is my minor child?
Distributions go to the trustee, not directly to the child. The trustee manages the money according to the trust terms and can distribute for the child’s education, healthcare, and needs. When the child reaches the age specified in the trust (typically 18, 21, or 25), they can receive distributions directly.
Does the custodian have to approve my trust before accepting it as beneficiary?
Generally yes. Custodians can request documentation to verify the trust is valid and meets IRS requirements. Provide a copy of the trust document or Certificate of Trust to make approval faster.
If I update my trust, do I need to update the beneficiary designation?
Only if the change affects the beneficiaries or distribution terms. If you update the trust to change the trustee or fix spelling errors but beneficiaries stay the same, the beneficiary designation at the custodian does not need to change. However, always notify the custodian of significant changes.
What if I want to leave different percentages to different children through the trust?
Specify percentages in the trust document. For example, “40% to Sarah, 35% to Michael, 25% to Jessica.” The trust controls the distribution percentages; the beneficiary designation form only names the trust as the beneficiary.
Can I use a trust as beneficiary if I have a small IRA?
Yes, but it might not be worth the cost. If the IRA is small (under $100,000), the legal costs of creating a trust might outweigh the benefits. For larger accounts or families with complications, a trust is more valuable.
What if the trustee dies or is unwilling to serve?
The trust document should name successor trustees. When the primary trustee dies or resigns, the successor takes over. If no successor is willing to serve, a court can appoint a trustee, but this is slow and expensive. Plan ahead and name multiple successor trustees.
Will the beneficiary designation override my will?
Yes. Beneficiary designations on retirement accounts transfer the account directly to the named beneficiary, bypassing your will. If your will says the money goes to your children but the beneficiary form names your trust, the trust receives the account. Always keep beneficiary designations and your will consistent.
