Roth IRA Trust: See-Through Rules, 10-Year Payout, and Taxes

Yes, you can name a trust as the beneficiary of your Roth IRA, and the account will keep its tax-free character if the trust is drafted correctly. The catch is that a Roth IRA trust beneficiary follows a different set of distribution rules than an individual, and getting the structure wrong can shorten the payout window to five years or push investment earnings into the highest federal tax bracket. The SECURE Act and the final Treasury regulations that took effect January 1, 2025 changed the mechanics enough that any trust drafted before 2020 needs a fresh look.

When a Trust Is Worth the Trouble

Naming a person directly is simpler and almost always the better choice when nothing about the beneficiary’s situation demands otherwise. A trust earns its place when you need something an outright inheritance can’t do.

Control over timing is the most common reason. A trust lets you dictate when and how much a beneficiary receives, which matters for young heirs, financially inexperienced ones, or anyone likely to burn through a lump sum. Distributions can be tied to age, education, or specific purchases.

Asset protection is the other major driver. Assets held inside a trust are generally shielded from a beneficiary’s creditors, lawsuits, and divorce settlements in ways that individually owned assets are not. For a beneficiary with a disability, a properly drafted special needs trust can hold inherited Roth IRA funds without disqualifying that person from means-tested benefits like Supplemental Security Income. The Social Security Administration excludes certain trusts established under Section 1917(d)(4)(A) of the Social Security Act from counting as a resource for SSI purposes.¹

If none of that applies, name the individual and move on. The trust layer costs money to draft, money to administer, and can cost tax dollars every year the trust holds investment income.

Making the Trust Qualify as a See-Through Trust

For a trust to be treated like an individual beneficiary rather than a faceless entity, the IRS must be able to look through it and identify the humans behind it. A trust that qualifies is called a see-through trust. A trust that fails is treated as a non-designated beneficiary, which forces the entire Roth IRA to be emptied within five years of the owner’s death.

The Treasury regulations set four requirements:²

The trust is valid under state law, or would be valid except for the fact that it has no assets yet.
The trust is irrevocable, or becomes irrevocable by its own terms at the IRA owner’s death. A revocable living trust satisfies this as long as its terms lock down on death.
Every beneficiary of the trust’s interest in the IRA is identifiable from the trust document. No open-ended classes, and no non-individual beneficiaries like charities or the estate, because only individuals count.
The documentation requirements in the regulations are met.

A widely repeated warning tells trustees they must deliver a copy of the trust to the IRA custodian by October 31 of the year after the owner’s death. That deadline applies to qualified employer plans like 401(k)s. For IRAs, the final regulations clarify that the trust documentation does not need to be provided to the IRA trustee, custodian, or issuer.³ The trust still has to satisfy the see-through rules and the documents should be ready for the IRS if requested, but the old custodian-delivery deadline doesn’t apply to IRAs.

Conduit or Accumulation: The Real Design Choice

Once a trust qualifies as see-through, its internal rules determine what happens to money coming out of the Roth IRA. The choice is really between tax efficiency and long-term control.

Conduit Trust

A conduit trust requires the trustee to pass every distribution from the Roth IRA straight through to the individual beneficiary. Money flows in from the IRA and immediately flows out to the heir. Nothing accumulates inside the trust.

The advantage is simplicity and tax efficiency. Because the funds never sit in the trust, they keep their tax-free character on their way to the beneficiary. The trade-off is that once the money passes through, the beneficiary owns it outright. If creditor protection or spending control was the point of using a trust, a conduit structure undoes that goal the moment funds are distributed.

Accumulation Trust

An accumulation trust gives the trustee discretion to hold Roth IRA distributions inside the trust instead of passing them out. The trustee can invest the funds and decide later when to distribute them. Asset protection and spending control survive intact.

The cost shows up on the tax return. The Roth IRA distributions themselves are still tax-free, but any dividends, interest, or capital gains those funds generate inside the trust are taxed at the trust’s own rates. Those rates are heavily compressed. In 2026, a trust hits the top 37% federal bracket on taxable income above $16,000.⁴ An individual doesn’t reach that bracket until income exceeds roughly $626,000. That gap can eat through returns quickly.

Choose a conduit trust when the beneficiary is a competent adult and the goal is preserving the tax-free benefit. Choose an accumulation trust when the beneficiary genuinely needs protection from creditors, from their own habits, or from losing government benefits, and the tax drag is an acceptable price.

The 10-Year Distribution Rule

Before the SECURE Act, most non-spouse beneficiaries could stretch inherited IRA distributions over their own life expectancies. That option is gone for most heirs. The law now requires the entire inherited Roth IRA to be fully distributed by the end of the tenth calendar year after the original owner’s death.⁵ The 10-year rule applies whether the trust is a conduit or an accumulation trust.

Inherited Roth IRAs have one significant advantage here. Because Roth IRA owners are never required to take distributions during their lifetimes, the owner is always treated as having died before their required beginning date. That matters because the final Treasury regulations, effective January 1, 2025, require annual distributions during the 10-year period only when the original owner died on or after their required beginning date.⁶

In practice, a trust that inherits a Roth IRA can leave the money invested and growing tax-free for the entire 10 years and withdraw everything in year 10. Nothing has to come out along the way. For an inherited traditional IRA, the math is worse because annual withdrawals may be required and each one is taxable. The Roth-plus-trust combination is at its most powerful for younger beneficiaries who benefit most from a full decade of tax-free growth.

With a conduit trust, the trustee empties the Roth IRA by year 10 and passes every dollar through to the beneficiary. With an accumulation trust, the Roth IRA still has to be emptied by year 10, but the distributed funds can stay inside the trust indefinitely after that. The IRA disappears at the 10-year mark; the trust continues, and the trustee still controls when the beneficiary sees any of it.

Who Can Still Stretch: Eligible Designated Beneficiaries

A narrow group of beneficiaries can still take distributions over life expectancy instead of being forced into the 10-year window. The tax code calls them eligible designated beneficiaries:⁵

A surviving spouse of the account owner.
A minor child of the account owner. Grandchildren and other minor relatives do not qualify.
A disabled individual as defined under federal tax law: unable to engage in any substantial gainful activity due to a medically determinable condition expected to result in death or be of long-continued and indefinite duration.⁷
A chronically ill individual: someone certified by a licensed health care practitioner as unable to perform at least two activities of daily living for at least 90 days, or requiring substantial supervision due to severe cognitive impairment.⁸
An individual not more than 10 years younger than the account owner, such as a close-in-age sibling or friend.

Qualification is measured as of the date of the account owner’s death. For a trust to use life expectancy payouts, every beneficiary of that trust must independently qualify. If even one named beneficiary falls outside these categories, the whole trust drops to the 10-year rule. Sloppy drafting causes real damage here: a trust naming both a disabled child and a healthy adult child as beneficiaries loses the stretch for both.

A minor child’s status is also temporary. Under the regulations a child counts as a minor until age 21, regardless of state law. Once the child turns 21 the 10-year clock starts, and the account must be fully distributed by the end of the year the child turns 31.

The Five-Year Holding Period

Roth IRA distributions are only fully tax-free if the account has satisfied a five-year holding period. The clock starts on January 1 of the first tax year the original owner made any Roth IRA contribution. Contributions come out tax-free regardless, but earnings can be taxable if the account hasn’t been open five years when withdrawn.⁹

For most inherited Roth IRAs this is a non-issue. If the original owner opened the account more than five years before death, everything comes out tax-free. If the owner died within the first five years, earnings may be taxable to the trust or its beneficiaries. The beneficiary inherits the original owner’s holding period, so what matters is when the owner first contributed, not when the beneficiary withdraws. It matters most for younger owners and for people who converted a traditional IRA to a Roth shortly before death.

When a Trust Isn’t the Right Answer for a Spouse

A surviving spouse who inherits a Roth IRA directly has options no trust can match:⁹

Roll the Roth IRA into their own. The account becomes theirs, with no lifetime required distributions, and the original owner’s five-year clock carries over.
Keep it as an inherited account and delay distributions until the deceased spouse would have turned 73, then take them over the survivor’s own life expectancy.
Elect the 10-year rule and distribute everything within 10 years.

A trust cannot roll an inherited Roth IRA into another IRA. Naming a trust as beneficiary instead of the spouse directly sacrifices that flexibility. The trade-off can still be worth it in second-marriage situations where children from a prior marriage need protection, or when the surviving spouse has creditor exposure. For a straightforward marriage, adding a trust between the account and the spouse usually costs more than it delivers.

Trust Tax Rates and Filing

An accumulation trust holding Roth IRA distributions will generate taxable investment income. The distributions themselves are tax-free, but dividends, interest, and capital gains earned inside the trust after the money leaves the IRA are not.

Trust brackets are designed to be punitive. In 2026 a trust reaches 37% at just $16,000 of taxable income.⁴ An individual doesn’t reach that rate until well over $600,000. The trustee can blunt the impact by distributing income to the beneficiary, which shifts the tax to the beneficiary’s lower individual rate, but distributing defeats the point of an accumulation trust.

Any trust with gross income of $600 or more in a tax year must file Form 1041.¹⁰ The trustee is personally responsible for timely filing and payment. When income is distributed, Schedule K-1 passes it through to the beneficiary’s individual return. Even a conduit trust may need to file in years when it briefly holds funds that generate income before passing them through.

Penalty for Missing the 10-Year Deadline

Failing to fully distribute an inherited Roth IRA by the end of year 10 triggers an excise tax of 25% on the amount that should have been withdrawn but wasn’t.¹¹ If the shortfall is corrected within two years, the penalty drops to 10%. SECURE Act 2.0 set those rates, replacing the previous 50% penalty that applied before 2023. Because a Roth IRA trust generally has no annual withdrawal obligation during the 10 years, the practical risk is simply forgetting the deadline and leaving money in the account past it.

How to Name the Trust as Beneficiary

The mechanics are straightforward. Complete a beneficiary designation form with your IRA custodian, entering the trust’s name, the date it was established, and the trustee’s name in place of an individual’s information. Some custodians provide a dedicated section for trust beneficiaries; others accept a written attachment.

A few points that trip people up:

The beneficiary form controls, not your will. Whatever your will says about your IRA is irrelevant. The designation on file with the custodian decides who inherits.
The trust must already exist. You can’t create it through the beneficiary form itself.
Divorce, the death of a beneficiary, or a new child should prompt a review of both the trust terms and the beneficiary designation. The two documents drift out of sync easily.
Trusts drafted before 2020 were built around the old stretch IRA rules. Distribution provisions written for life-expectancy payouts can produce strange results under the 10-year framework. An attorney experienced in retirement account planning should review any trust that hasn’t been updated since the SECURE Act.

Naming a trust as a Roth IRA beneficiary is a decision where the legal fees for getting it right are a small fraction of the tax cost of getting it wrong. The trust structure, the beneficiary designations, and the distribution terms all need to agree with each other, and the margin for error under the current rules is narrower than it used to be.
