Hidden Risks of Naming a Trust as Your IRA or 401(k) Beneficiary

EXECUTIVE SUMMARY
Naming your trust as the beneficiary of your IRA or 401(k) can be a powerful estate planning tool, but it comes with significant complexities and trade-offs.
Recent IRS regulations, particularly the final regulations issued in July 2024, have made several significant changes affecting individuals who have named a trust as the beneficiary of their IRA or 401(k). These changes address required minimum distributions (RMDs), beneficiary classifications, documentation requirements, and tax implications.
If you have a trust, it may no longer be prudent to name your trust as your 401(k) or IRA beneficiary. You may need to consult with your estate planning attorney to confirm that naming your trust as the beneficiary is still a valid designation.
If your trust document is over five years old, you may need to consult your estate planning attorney to modify your trust or update your beneficiary designations to avoid unintended accelerated distribution timeframes or subject the distributions to steep trust tax rates.
Before discussing the latest tax regulations and the implications of naming a trust as your IRA or 401(k) beneficiary, let’s look at the pros and cons of doing so:
PROS OF NAMING A TRUST AS AN IRA BENEFICIARY
• Control Over Distributions: A trust allows you to set specific terms for how and when assets are distributed. This is particularly useful if your beneficiaries are minors, have special needs, or may not be financially responsible [9][10][11][12].
• Protection for Vulnerable Beneficiaries: Trusts can protect beneficiaries who are minors, disabled, or have issues with creditors, addiction, or poor financial decision-making [9][13][14][11][12].
• Asset Protection: A trust can safeguard assets from a beneficiary’s creditors, divorce, or lawsuits [10][12].
• Estate Planning for Blended Families: Trusts can ensure assets are distributed according to your wishes, such as providing for a spouse during their lifetime with the remainder going to children from a previous marriage [13][14][10][12].
• Privacy: Distributions through a trust avoid probate, keeping your estate details private [10].
• Special Needs Planning: A properly structured trust can provide for a beneficiary with special needs without disqualifying them from government benefits [14][10][11].
• Contingency Planning: Trusts can specify what happens if a beneficiary dies before receiving their full share, offering more control over the ultimate disposition of assets [12].
CONS OF NAMING A TRUST AS AN IRA BENEFICIARY
• Accelerated Taxation and RMD Rules: Trusts are subject to Required Minimum Distributions (RMDs) based on the oldest beneficiary’s life expectancy, which can accelerate withdrawals and taxes compared to naming individuals directly [9][13][11].
Under the SECURE Act, most non-spouse beneficiaries, including trusts, must withdraw the entire account within 10 years, eliminating the “stretch IRA” for most cases [14][10][11].
• Potential for Higher Taxes: Trusts reach the highest federal income tax rate much faster than individuals. If the trust accumulates income instead of distributing it, this can result in significantly higher taxes [15][10].
• Loss of Spousal Rollover: Naming a trust as beneficiary means a surviving spouse cannot roll the account into their own IRA, losing the ability to defer taxes over their lifetime [14].
• Increased Complexity and Cost: Administering a trust as a retirement account beneficiary involves more paperwork, legal compliance, and potentially higher administrative costs [13][15][10].
• Risk of Non-Compliance: If the trust is not drafted correctly as a “see-through” (or “look-through”) trust (see below), it may trigger even more accelerated distribution rules, such as the five-year distribution rule [15][11].
• Plan Restrictions: Some employer plans may not allow trusts as beneficiaries or may require lump-sum distributions, which could trigger full immediate taxation [13].
• No Probate Avoidance for Trust Assets: While retirement accounts avoid probate when a beneficiary is named, naming a trust does not provide additional probate avoidance for the retirement account, though it does for assets distributed from the trust [11].
When Naming a Trust as Beneficiary Makes Sense
• You have minor, disabled, or financially irresponsible beneficiaries.
• You want to control the timing and amount of distributions.
• You need to protect assets from creditors or divorce.
• You have a blended family and want to ensure specific inheritance outcomes.
• You have a beneficiary who relies on government benefits.
When It May Not Be Advantageous
• Your beneficiaries are financially responsible adults.
• You want to maximize tax deferral and minimize complexity.
• Your spouse is the primary beneficiary and would benefit from rollover options.
KEY TAX CHANGES AND THEIR EFFECTS
Before the SECURE Act, passed in December 2019, IRA beneficiaries enjoyed a long “stretch” of time to take distributions from the IRAs they inherited. In general, beneficiaries could distribute the inherited IRA assets over the remainder of their lifetimes using the IRS required minimum distribution rules.
That stretch was largely eliminated for most IRA beneficiaries who inherited an IRA from a decedent starting in 2020. It took the IRS over 4 1/2 years from the passage of the SECURE Act to finalize regulations surrounding distributions from post-2019 inherited IRAs.
1. Required Minimum Distributions (RMDs) and the 10-Year Rule
As mentioned above, the SECURE Act and its subsequent regulations essentially eliminated the "stretch IRA" for most non-spouse beneficiaries, including trusts, replacing it with a 10-year payout rule. This means that, in most cases, all funds in an inherited IRA or 401(k) must be distributed by the end of the 10th year following the account holder's death.
If the account owner died after their required beginning date (RBD), annual RMDs must be taken during years 1–9, with the entire balance distributed by year 10.
If the account owner died before their required beginning date (RBD), annual required minimum distributions (RMDs) are not required in years 1–9. Instead, the entire inherited IRA or retirement account balance must be distributed by the end of the 10th year following the year of the original owner’s death.
The RBD for most IRA owners is 70-1/2 to age 73 (soon to be age 75). Remember that the “M” in RMD is the minimum you must distribute. Depending on the size of the IRA, more than the minimum distribution will often make more sense.
Only "Eligible Designated Beneficiaries" (EDBs), such as spouses, minor children (until age 21), disabled or chronically ill individuals, or beneficiaries less than 10 years younger than the decedent, can still use the stretch distribution based on their life expectancy.
2. Trust Types and Beneficiary Analysis
The IRS continues to recognize "see-through" (or "look-through") trusts, which allow the trust's individual beneficiaries to be treated as the IRA's beneficiaries for RMD purposes.
To qualify as a see-through trust under IRS rules, the trust must meet specific criteria that allow its beneficiaries to be treated as direct beneficiaries of an inherited IRA or 401(k). These requirements ensure the trust can utilize stretch distributions or the 10-year rule based on beneficiary status (i.e., EDB or non-EDB).
Here are the key requirements of a see-through trust:
a. Validity Under State Law
The trust must be legally valid in the state where it was created. This typically requires proper execution, witnessing, and notarization of the trust document.
b. Irrevocability Upon Death
The trust must either be irrevocable from inception or become irrevocable upon the account owner’s death. Revocable trusts that convert to irrevocable status at death are acceptable.
c. Identifiable Beneficiaries
All trust beneficiaries must be clearly named, identifiable, and eligible individuals (e.g., people, not charities or other entities). This ensures the IRS can "see through" the trust to determine distribution timelines based on beneficiary life expectancies or the 10-year rule.
If a trust is not a see-through trust, it may be considered a:
-
Conduit Trust: All IRA distributions must be immediately passed to the trust's beneficiaries. Taxes are paid at the beneficiaries' individual rates, but the 10-year rule generally applies unless all beneficiaries are EDBs.
OR
-
Accumulation (Discretionary) Trust: Distributions can be retained in the trust, which pays taxes at higher trust tax rates. All trust beneficiaries are considered when determining the payout period, and the 10-year rule usually applies.
The Final Regulations allow trusts that split into separate subtrusts for each beneficiary upon the account holder's death to apply RMD rules based on each subtrust's beneficiary status. This can preserve stretch treatment for EDBs even if other beneficiaries are subject to the 10-year rule.
3. Documentation Requirements
For IRAs, the IRS has eliminated the requirement for trustees to provide detailed trust documentation to the IRA custodian. Now, only a list of trust beneficiaries and their entitlements may be required, greatly simplifying compliance for see-through trusts.
Some documentation requirements remain for 401(k) and other employer plans, but they have been simplified.
4. Tax Consequences
As mentioned above, trusts reach the top income tax bracket much faster than individuals. In 2024, trust income over $15,200 is taxed at 37%, whereas individuals do not hit this rate until much higher income levels. This can result in significant tax bills if IRA distributions are accumulated in a trust rather than paid to beneficiaries.
Lump-sum distributions or failing to comply with the new rules can result in accelerated taxation and potential penalties.
5. Special Provisions and Clarifications
The IRS clarified that if a trust divides into separate subtrusts immediately upon the account owner's death, each subtrust is analyzed separately for RMD purposes.
If trust terms or beneficiaries are modified after the account owner's death (by September 30 of the following year), these changes will affect RMD calculations as if they were always part of the original trust.
Payments made "for the benefit of" a beneficiary (such as to a custodial account for a minor) are treated as direct payments to the beneficiary for RMD purposes.
PRACTICAL CONSIDERATIONS
Most trusts named as IRA or 401(k) beneficiaries will now face the 10-year payout rule, with fewer opportunities for long-term tax deferral.
Under the new rules, trusts must be carefully analyzed and possibly restructured to maximize tax efficiency and achieve estate planning goals.
Simplifying documentation requirements reduces administrative burdens for IRA trusts, but not necessarily for employer plans.
High trust tax rates make accumulation trusts less attractive for holding retirement assets over the long term.
ACTION MAY BE REQUIRED
If your IRA or 401(k) names your trust as a beneficiary, it’s advisable to consult with your estate planning attorney to ensure that, in light of the recent tax regulations, naming the IRA as beneficiary is still prudent.
If you’re unsure your trust is considered a see-through trust, consult with your estate planning attorney to determine if the trust must be modified to ensure that the 10-year distribution for beneficiaries remains intact. Otherwise, that 10-year period might be inadvertently shortened to five years, or worse, subject distributions to overly steep trust tax rates.
Whether you have a trust or have named your trust as a beneficiary of your IRA or 401(k), now is a good time to check the beneficiary designations on all of your retirement accounts and insurance policies to ensure they are up to date and reflect all of your recent life changes. If something should happen to you, your loved ones will be most grateful.
