The Trustee’s Election.

The deadline is not in the statute but in the regulations: an election under section 1361(e) must be filed within the period prescribed for a qualified subchapter S trust election, which is the 16-day-and-2-month period beginning on the day the S corporation stock is transferred to the trust. Treas. Reg. § 1.1361-1(m)(2)(iii); Treas. Reg. § 1.1361-1(j)(6)(iii)(A); see Rev. Proc. 2013-30, § 2.02(1).

In the space of a week this summer, the IRS released two private letter rulings in which exactly that had happened, and in which the corporation had to go to the National Office to get its status back. Both taxpayers received relief. Neither result was automatic, neither was cheap, and neither is precedent for anyone else. The rulings are worth reading closely because the structure they describe — an operating company taxed as an S corporation, with its shares spread across a set of family trusts — is one of the most ordinary arrangements in private wealth planning, and the failure they describe is one of the most ordinary administrative lapses.

PLR 202635005 was released on August 28, 2026; the letter itself is dated June 2, 2026. PLR 202635005 (released Aug. 28, 2026; dated June 2, 2026; PLR-119581-25). According to the facts submitted, a State corporation (identified only as X) had previously elected S status. On a single date, shares of X were transferred to each of five trusts. X represented that each trust qualified as an electing small business trust (“ESBT”) on that date, but the trustees never made the elections under § 1361(e)(3). The consequence, as the ruling states it, is that X had ineligible shareholders on the transfer date, and its S election terminated on that date.

Chief Counsel concluded that the termination was inadvertent within the meaning of § 1362(f) and that X would be treated as continuing to be an S corporation from the transfer date onward. The relief carried conditions: within 120 days of the letter, the trustees had to file ESBT elections effective as of the transfer date, and the trusts had to file returns (including amended returns) for all open years reflecting ESBT treatment, with a copy of the ruling attached.

PLR 202634010, released a week earlier on August 21, 2026 and dated May 22, 2026, involved a sharper version of the same problem. PLR 202634010 (released Aug. 21, 2026; dated May 22, 2026; PLR-120307-25). Shares were transferred to six trusts in three waves, two trusts at a time, on three separate dates. None of the six trustees filed a timely ESBT election. The S election terminated on the first transfer date, and the ruling notes that each later wave would independently have terminated it had it not already ended. Relief was again granted, but on heavier terms: ESBT elections for all six trusts effective as of their respective transfer dates, timely amended returns by the trusts and their beneficiaries for all open years, and, as an adjustment under § 1362(f)(4), a payment of an amount redacted in the public copy, due within 45 days. The ruling adds a sentence that every trustee should read slowly:

In that event, X was required to notify the service center that its S election had terminated on the first transfer date.

Both letters close with the standard reservations. Chief Counsel expressed no view on whether the corporations were otherwise eligible to be S corporations or whether the trusts were otherwise eligible to be ESBTs, and neither ruling verified the facts submitted; each is “subject to verification on examination.” Each is also directed only to the taxpayer that requested it and, under § 6110(k)(3), may not be used or cited as precedent. PLR 202635005, at 4; PLR 202634010, at 5; 26 U.S.C. § 6110(k)(3).

Subchapter S is a tax regime built for owners who are people. A “small business corporation” may not have more than 100 shareholders, may not have a nonresident alien shareholder, may have only one class of stock, and, most relevant here, may not have as a shareholder anyone who is not an individual, other than an estate, certain exempt organizations, and the trusts specifically described in § 1361(c)(2). 26 U.S.C. § 1361(b)(1).

That list of permitted trusts is short. It includes a grantor trust whose deemed owner is a U.S. citizen or resident; certain trusts for a limited two-year period after the deemed owner’s death or after stock is transferred under a will; voting trusts; and the ESBT. 26 U.S.C. § 1361(c)(2)(A)(i)–(v). Separately, § 1361(d) permits a qualified subchapter S trust (“QSST”), but the QSST is a narrow instrument: it must have only one income beneficiary, must distribute (or be required to distribute) all of its income to that beneficiary, and may not distribute corpus to anyone else during that beneficiary’s lifetime. 26 U.S.C. § 1361(d)(3); see Rev. Proc. 2013-30, § 2.02(1).

Those QSST requirements are close to the opposite of how a protective family trust is drafted. A discretionary trust with several beneficiaries, a spendthrift clause, and a trustee who decides whether and when to distribute cannot be a QSST. For that trust, once any grantor-trust status has ended, the ESBT is usually the only door into Subchapter S. And the ESBT is, by statute, an electing trust: one of the three elements of the definition is that “an election under § 1361(e) applies to such trust.” 26 U.S.C. § 1361(e)(1)(A)(iii), as quoted in PLR 202635005, at 3. A trust can satisfy every substantive requirement — only eligible beneficiaries, no interest acquired by purchase — and still be an ineligible shareholder because the paper was never filed.

The election is the trustee’s to make, not the corporation’s or the beneficiaries’. 26 U.S.C. § 1361(e)(3). It is filed as a signed statement with the service center where the S corporation files its return, and it must be filed within the same period the regulations prescribe for a QSST election: the 16-day-and-2-month period beginning on the day the stock is transferred to the trust. Treas. Reg. § 1.1361-1(m)(2)(i), (iii), as summarized in PLR 202634010, at 3; Rev. Proc. 2013-30, § 2.02(1).

Two features make this a genuine single point of failure. First, the consequence under § 1362(d)(2) is automatic: an S election terminates whenever the corporation ceases to be a small business corporation, and the termination is “effective on and after the date of cessation.” 26 U.S.C. § 1362(d)(2)(A)–(B). No notice is sent. The corporation keeps filing Forms 1120-S, the shareholders keep reporting pass-through income, and the problem sits undetected until a buyer’s diligence team, an auditor, or a new adviser asks to see the elections. Second, the obligation falls on a party who may never have been involved in the corporation’s tax compliance. The company’s return preparer may not know the trust exists as a shareholder; the trustee may assume the company’s advisers handled it.

The rulings do not describe the tax that would have followed had relief been denied, and the numbers in any given case turn on its facts. The general shape is not in doubt. A corporation whose S election has terminated is a C corporation for the years that follow. Its income is taxed at the corporate level, and distributions that the shareholders treated as tax-free pass-through amounts may instead be dividends. Absent consent from the Secretary, a corporation whose election terminates generally cannot re-elect S status for five taxable years. 26 U.S.C. § 1362(g). If the business is later sold, the difference between an asset sale out of an S corporation and one out of a C corporation can be substantial. In a long-lapsed case, the exposure compounds year over year.

That is why both taxpayers went to the trouble of a ruling.

The IRS has for years offered a way to fix late ESBT and QSST elections without a letter ruling. Rev. Proc. 2013-30 consolidated earlier procedures and describes itself as providing “the exclusive simplified methods” for relief for late S corporation, ESBT, QSST, and QSub elections. Rev. Proc. 2013-30, § 1. Relief under it is granted in lieu of the letter ruling process, and user fees do not apply. Id. § 3.01.

The procedure has four general gates. The trust must have been intended to be an ESBT (or QSST) as of the effective date. The request must be made within 3 years and 75 days after that effective date. The failure to qualify must have been “solely because the Election Under Subchapter S was not timely filed” by its due date. And, for a termination caused by a missed ESBT or QSST election, the failure must have been inadvertent, with the corporation and the person seeking relief having “acted diligently to correct the mistake upon its discovery.” Id. § 4.02(1)–(4). The late election is filed with a statement explaining the inadvertence and the corrective steps, signed under penalties of perjury, and must be labelled at the top as filed pursuant to the revenue procedure. Id. § 4.03(1), (3).

Neither ruling says why the taxpayer did not use Rev. Proc. 2013-30, and it would be speculation to assign a reason to either. The redacted dates make it impossible to tell from the public copies whether the 3-year-and-75-day window had closed. What can be said is that the revenue procedure itself directs an entity that does not meet its requirements to seek a letter ruling instead, id. § 3.02, and that the common reasons a taxpayer ends up in the ruling process are the ones its gates imply: the lapse was discovered too late; the trust had some other qualification defect beyond the missing election; or returns were not filed consistently with the intended treatment. Practitioner commentary has observed that, unlike late S corporation elections, the relief period for late ESBT and QSST elections under the revenue procedure cannot be extended beyond 3 years and 75 days, so a lapse found after that point must go through the letter-ruling process. How S elections go wrong and how to fix them, The Tax Adviser (May 2025) (noting also that Rev. Proc. 2022-19 later expanded the categories of S corporation errors the IRS will address without a ruling; the current status of any window should be confirmed before relying on it). The conditions in PLR 202634010, requiring amended returns by the beneficiaries and a separate payment, suggest — though the ruling does not say so — that at least some years had not been reported in a manner consistent with ESBT treatment.

The ruling route is not trivial. The same commentary reported that the user fee for a § 1362(f) request received after February 1, 2025 was $43,700, and that the IRS issued 148 such letter rulings in 2024. Id. (user fees are revised periodically in the first revenue procedure of each year; the current figure should be confirmed before any filing). To that fee add professional time to assemble the facts, shareholder consents to adjustments, the wait — in PLR 202635005, roughly six and a half months passed between the request letter of November 17, 2025 and the ruling — and the post-ruling compliance with its own deadlines.

Section 1362(f) lets the Secretary treat a terminated corporation as an S corporation if the circumstances were inadvertent, corrective steps were taken within a reasonable period after discovery, and the corporation and every person who was a shareholder during the relevant period agree to whatever adjustments the Secretary requires. 26 U.S.C. § 1362(f). The regulations put the burden of proving inadvertence on the corporation. As Rev. Proc. 2013-30 summarizes them, it tends to establish inadvertence that the terminating event was not reasonably within the corporation’s control and was not part of a plan to terminate, or that it happened without the corporation’s knowledge “notwithstanding its due diligence to safeguard against such an event.” Rev. Proc. 2013-30, § 2.02(2) (summarizing Treas. Reg. § 1.1362-4(b)).

That last phrase is worth dwelling on. Relief for a missed election is generous in practice, but it is framed as relief for a lapse that occurred despite reasonable care. A structure with no process for identifying new trust shareholders and calendaring their elections is not in the strongest position to say so.

None of this changes the creditor-protection analysis of a well-built trust. A valid discretionary trust with an independent trustee remains what it was the day before an election was missed; a tax-status problem at the operating company is not, in itself, a crack a creditor can walk through.

But planners who build these structures should be candid about where the weak points of a mature trust actually tend to lie. They are rarely in the drafting. They are in the administration. A trust whose trustee cannot show that it tracked the shares it holds, filed the elections those shares required, and reported consistently afterward is a trust whose administration invites questions: from the IRS, from a buyer, from beneficiaries who bear the cost of a retroactive C corporation, and, in a contested setting, from anyone looking for evidence that the trustee was not really in charge. An independent trustee’s value is not only that it says no to the settlor. It is that it does the unglamorous things — the calendar, the filings, the confirmations — that make the structure’s substance match its paper.

The rulings also point to a quieter risk. Depending on the instrument and governing law, a trustee that fails to file may face questions in its own right from beneficiaries who absorb the cost of the lapse or of the cure. A trustee that has held operating-company S stock for years without confirming its elections may be carrying that risk whether or not anyone has noticed yet.

These are general observations; how any of them applies depends on the governing instrument, the corporation’s history, and the facts of each transfer.

1. Treat every transfer of S stock into a trust as a tax event with its own deadline. The 16-day-and-2-month period runs from the transfer, not from year-end or the return due date. Gifts, sales to grantor trusts, decanting, division of a trust into separate shares, and funding of sub-trusts at a death can each create a new shareholder and a new clock.
2. Watch the moment grantor-trust status ends. A grantor trust is a permitted shareholder while the deemed owner is alive, and for two years after death. 26 U.S.C. § 1361(c)(2)(A)(i)–(ii). The switch from grantor to non-grantor status, whether by death, release of a power, or otherwise, is exactly when a family trust most often needs an ESBT or QSST election and most often lacks one.
3. Match the election to the instrument. A discretionary, spendthrift, multi-beneficiary trust generally cannot be a QSST. If the trust is meant to stay discretionary, the ESBT is the route, and its income-tax cost — the S portion of an ESBT is taxed at the trust level under its own rules — belongs in the planning conversation before the stock moves, not after. See 26 U.S.C. § 641(c).
4. Confirm, do not assume. Obtain a copy of each election as filed, with proof of filing, for the trust file and the corporation’s file. In diligence on an existing structure, ask for the election for every trust on the shareholder ledger, including trusts that have held shares for many years.
5. If a lapse is found, time matters. Rev. Proc. 2013-30 is available only within 3 years and 75 days of the intended effective date and only when the missed election was the sole defect. After that, the ruling process is the path, with a user fee, adjustments, and conditions that can void the relief if not met.
6. Read the conditions of any ruling as deadlines. In PLR 202634010 the payment was due in 45 days and the elections and amended returns in 120. A ruling that is null and void for missed conditions leaves the corporation where it started, with less time.

The two rulings end well for the taxpayers who asked. They end well, though, only because someone found the lapse, assembled the facts, persuaded Chief Counsel that it was inadvertent, and then met a new set of deadlines. The relief exists for those who discover the problem and pursue it; a trust that never looks does not benefit from it.

For families whose operating businesses sit inside protective trusts, the lesson is not that the structure is fragile. It is that the structure is administered, and that administration includes a two-month-and-sixteen-day calendar entry that nobody else is going to make.

This note is for general information and discussion. It is not tax or legal advice for any person or structure, and private letter rulings may not be relied on or cited as precedent by anyone other than the taxpayers who received them. The treatment of any trust holding S corporation stock turns on its terms and facts and should be reviewed with qualified tax counsel.
