Naming a Trust as IRA Beneficiary in PA

Naming a trust as the beneficiary of an IRA or 401(k) is one of the most consequential (and most frequently botched) estate planning decisions. Done correctly, it provides control over who receives the money, when they receive it, and protection from creditors and divorcing spouses. Done incorrectly, it accelerates the entire tax bill and defeats the purpose.

The rules governing this area are primarily federal (the SECURE Act of 2019, SECURE 2.0 Act of 2022, and IRS final regulations (TD 10001, July 2024)) but the Pennsylvania inheritance tax consequences add a layer of complexity that national planning guides routinely miss.

The Basic Problem

When you name an individual as IRA beneficiary, the IRS knows exactly who it is dealing with: a person with an age and a life expectancy. Distribution rules follow from there. When you name a trust , the IRS cannot see through the entity to the beneficiaries; unless the trust qualifies as a “see-through trust” (sometimes called a “look-through trust”).

If the trust does not qualify, the entire IRA must be distributed within 5 years of the account owner’s death (if the owner died before the required beginning date) or over the owner’s remaining life expectancy. That is usually far worse than the 10-year rule that applies to most designated beneficiaries.

See-Through Trust Requirements

A trust qualifies as a see-through trust if it meets four requirements under Treasury Regulation § 1.401(a)(9)-4:

• The trust is valid under state law (or would be but for the fact there is no corpus)
• The trust is irrevocable or becomes irrevocable upon the account owner’s death
• The trust beneficiaries are identifiable from the trust instrument
• A copy of the trust instrument is provided to the plan administrator by October 31 of the year following the year of the owner’s death

Pennsylvania’s Uniform Trust Code (20 Pa.C.S. Ch. 77) readily satisfies the “valid under state law” requirement. The more critical question is how the trust is structured: as a conduit trust or an accumulation trust.

Conduit Trusts

A conduit trust requires the trustee to distribute all retirement account distributions immediately to the trust beneficiary. The money passes through the trust like a conduit. Because the IRS can identify the ultimate beneficiary and ignore the trust, the beneficiary’s status (eligible or non-eligible designated beneficiary) determines the distribution timeline.

Advantage: Simplicity. The trust qualifies as see-through, and the distribution period is clear. Distributions are taxed at the beneficiary’s individual rate, not the compressed trust rate.

Disadvantage: No asset protection. Once the RMD passes through to the beneficiary, it is theirs; exposed to creditors, divorcing spouses, and spending. Under the SECURE Act’s 10-year rule, the entire account must be distributed (and passed through) within 10 years, potentially requiring large distributions to a beneficiary you wanted to protect.

Accumulation Trusts

An accumulation trust allows (but does not require) the trustee to retain distributions inside the trust rather than passing them through. This preserves asset protection and gives the trustee discretion over timing and amounts.

Advantage: Control and protection. The trustee decides when and how much the beneficiary receives, protecting against creditors, immaturity, and poor judgment.

Disadvantage: Tax compression. Amounts retained in the trust are taxed at trust income tax rates, which reach the top federal bracket (37%) at just $16,000 (2026, per Rev. Proc. 2025-32). Additionally, all “countable beneficiaries” of the trust matter for determining the distribution timeline; if any beneficiary of an accumulation trust is not a designated beneficiary (for example, if a charity or the estate is a remainder beneficiary), the account owner is treated as having no designated beneficiary, so the 5-year rule or the owner’s remaining life expectancy applies instead of the 10-year rule. One narrow exception matters in special needs planning. If the trust is an applicable multi-beneficiary trust, meaning no one other than the disabled or chronically ill beneficiary has any right to the account until that beneficiary dies, a charitable organization described in IRC § 408(d)(8)(B)(i) is treated as a designated beneficiary for the limited purpose of qualifying the trust. Treas. Reg. § 1.401(a)(9)-4(g).

The SECURE Act’s Impact

Before the SECURE Act, conduit trusts were the standard recommendation because the “stretch IRA” allowed distributions over the beneficiary’s life expectancy. The SECURE Act replaced the stretch with a 10-year distribution requirement for most non-spouse beneficiaries. This fundamentally changed the analysis:

Under the stretch, a conduit trust passed out small annual amounts over decades; manageable. Under the 10-year rule, the entire account must be emptied within 10 years, which means a conduit trust now forces potentially large lump sums to the beneficiary within that window; undermining the protection the trust was meant to provide.

This has made accumulation trusts more attractive for families who prioritize control over tax efficiency, especially when the beneficiary has creditor issues, a special needs situation, or is simply young.

Pennsylvania Inheritance Tax

Here is where national planning guides fall short. Pennsylvania taxes inherited retirement accounts based on the beneficiary’s relationship to the decedent , not the trust itself. Under 72 P.S. § 9116, the applicable rates are:

• Spouse: 0%
• Lineal descendants (children, grandchildren): 4.5%, except that a transfer to or for the use of the decedent’s child age 21 or younger from a natural, adoptive, or step parent is taxed at 0% where the parent died after December 31, 2019 (72 P.S. § 9116(a)(1.4))
• Siblings: 12%
• All others: 15%

When an IRA passes through a trust, the tax is calculated based on who ultimately receives the distributions. With a conduit trust, this is straightforward; the conduit beneficiary’s relationship determines the rate. With an accumulation trust, the analysis is more complex because the trustee has discretion over who receives what.

PA inheritance tax on a traditional IRA or 401(k) is generally computed on the date-of-death value of the full value of the account , at the beneficiary’s relationship rate, not as distributions are taken. The return and payment are due within nine months of death (with a discount if paid within three months), so for most accounts the tax is an upfront cost rather than one spread over the next 10 years. There is an important PA-specific exception, however: a traditional IRA or 401(k) is exempt from PA inheritance tax if the non-disabled owner died before age 59 1/2, in which case the tax on that account is $0. The Department of Revenue has not published a Roth-specific rule. Applying the same before-59 1/2 test the Department applies to traditional accounts, the contributions portion of a Roth IRA is generally treated as taxable at any age, because the owner could always withdraw contributions without penalty, while only the earnings portion gets the benefit of the before-59 1/2 exemption. Confirm the treatment with the Department before filing.

Which Structure Is Right?

There is no universal answer. The choice depends on competing priorities:

Tax efficiency favors conduit trusts, since income is taxed at the beneficiary’s individual rate rather than the compressed trust rate. Asset protection favors accumulation trusts, since the trustee controls the timing and amount of distributions. Simplicity favors naming individuals directly, with no trust complexity at all. And for eligible designated beneficiaries (surviving spouses, minor children, and disabled or chronically ill individuals) who can still stretch distributions, a conduit trust remains a more workable structure.
