IRS Rules on Inadvertent Termination of S Corporation Status Due to Funding Agreements

IRS Grants Relief for Inadvertent Termination of S Corporation Status

The IRS ruled in PLR-101721-26 that an S corporation’s termination of status was inadvertent under § 1362(f) and granted relief, provided the taxpayer complies with the conditions set forth in the ruling. The IRS concluded that the termination resulted from an unintentional violation of S corporation eligibility rules—specifically, the presence of ineligible shareholders and a potential second class of stock—rather than tax avoidance or retroactive planning. Relief under § 1362(f) remains valid only if the taxpayer maintains the corrected structure and adheres to the representations made in the ruling.

Funding Agreements Trigger Potential Termination of S Corporation Status

The potential termination of Sub’s S corporation election arose from funding agreements that inadvertently violated eligibility rules under the Internal Revenue Code. Sub, a domestic corporation incorporated under State 1 law, initially elected S corporation status effective Date 1, with individuals A and B owning 100% of its stock. On Date 2, Sub entered into a funding agreement with C, a business entity ineligible to own S corporation stock under § 1361(b)(1)(B), which restricts S corporation shareholders to individuals, estates, certain trusts, and tax-exempt organizations. A subsequent funding agreement with D on Date 3—also an ineligible shareholder—compounded the issue.

These funding agreements posed dual risks under § 1361(b)(1)(D), which prohibits S corporations from having more than one class of stock unless the differences are solely in voting rights. The agreements potentially created a second class of stock by granting C and D disproportionate economic rights or conversion features that materially altered their interests relative to A and B’s common stock. The agreements’ terms were not disclosed in the ruling, but the IRS later noted that their structure could have triggered a termination of Sub’s S election under § 1362(d)(2), which mandates termination if an S corporation violates eligibility requirements.

To address perceived structural issues, Sub’s owners pursued a reorganization under § 368(a)(1)(F), a transaction designed to qualify as a reorganization where one corporation acquires the stock of another in a manner that results in the target becoming a subsidiary. On Date 4, X, a newly formed corporation under State 2 law, was created. On Date 5, A and B contributed all of Sub’s stock to X, causing Sub to become a subsidiary of X. X then elected to treat Sub as a Qualified Subchapter S Subsidiary (“QSub”) under § 1361(b)(3)(B), effective Date 5, which requires 100% ownership of the subsidiary by an S corporation. On Date 6, Sub converted to a State 2 limited liability company, and X contributed all of its membership interests in Sub to A Corp, an association taxable as a corporation.

The reorganization and QSub election were structured in reliance on Rev. Rul. 64-250, 1964-2 C.B. 33 and Rev. Rul. 2008-18, 2008-1 C.B. 674, which address S corporation eligibility in reorganizations and QSub elections. However, the funding agreements’ potential to create a second class of stock and involve ineligible shareholders threatened the validity of Sub’s S election and X’s QSub election. The taxpayer later represented to the IRS that the circumstances leading to the potential termination were inadvertent and not motivated by tax avoidance or retroactive planning, but the agreements’ structural flaws remained unresolved at the time of discovery.

IRS Rules Termination Was Inadvertent Under § 1362(f)

The IRS analyzed the taxpayer’s situation under § 1362(f), which permits relief from an inadvertent termination of an S corporation election if the corporation meets four statutory conditions. First, the termination must result from a failure to meet § 1361(b) requirements (e.g., single-class-of-stock rule) or a termination under § 1362(d)(2). Here, the funding agreements threatened Sub’s S status by creating a second class of stock under § 1361(b)(1)(D), which prohibits corporations from having more than one class of stock unless the differences are only in voting rights. The IRS noted that Treas. Reg. § 1.1361-1(l)(1) defines a second class of stock as any stock that confers materially different distribution or liquidation rights, and the agreements in question altered economic rights in a way that violated this standard.

Second, the IRS required the taxpayer to demonstrate that the circumstances were “inadvertent” within the meaning of § 1362(f)(2). The taxpayer represented that the termination risk was not motivated by tax avoidance or retroactive planning but arose from structural flaws in the agreements that were not immediately apparent. The IRS accepted this representation, concluding that the error was unintentional rather than deliberate. This aligns with prior guidance such as Rev. Rul. 64-250, which emphasizes continuity of eligibility and the IRS’s willingness to grant relief where compliance failures are not willful.

Third, the taxpayer had to take corrective action “within a reasonable period” after discovering the issue, as required by § 1362(f)(3). While the ruling does not specify the exact timeline, it implies the taxpayer acted promptly to address the structural flaws, consistent with Treas. Reg. § 1.1362-4(a), which requires steps to restore eligibility or obtain necessary consents. Finally, the taxpayer and affected shareholders agreed to make adjustments as required by the IRS under § 1362(f)(4) and Treas. Reg. § 1.1362-4(d), which allows the Commissioner to impose conditions to ensure consistent tax treatment.

The IRS concluded that the termination was inadvertent and granted relief, treating Sub as an S corporation from Date 2 to Date 5, provided the election was otherwise valid. Similarly, the IRS ruled that X’s QSub election, which may have been ineffective due to Sub’s failure to meet § 1361(b)(3)(B) requirements (100% ownership by an S corporation), was also inadvertent and granted relief for the period from Date 5 to Date 6, subject to the same conditions. The ruling remains valid only if the parties comply with a specific condition: none of the affected parties may treat C and D as holding equity in Sub for federal tax purposes, including determining holding periods under § 1202. Failure to adhere to this condition renders the ruling null and void, and Sub must notify the IRS if the condition is not met.

Conditions and Limitations of the IRS Ruling

The IRS imposed strict conditions to ensure the ruling’s validity under § 1362(f), which permits relief for inadvertent S corporation terminations. The ruling remains valid only if X, Sub, A, B, C, and D refrain from treating C and D as holding equity in Sub for any federal tax purposes, including the determination of holding periods under § 1202. This condition is explicitly tied to the IRS’s authority under § 1.1362-4(d), which governs the procedural requirements for inadvertent termination relief. The IRS warned that failure to adhere to this condition renders the ruling null and void, effectively reinstating the S corporation termination as of Date 2.

If the condition is violated, Sub must notify the service center with which it filed its S corporation election that its election terminated on Date 2 and that its QSub election on Date 5 was ineffective. This notification requirement ensures the IRS can promptly address any noncompliance, preventing continued reliance on an invalid ruling. The IRS further clarified that the ruling is non-precedential under § 6110(k)(3), meaning it cannot be cited as authority in other cases. This limitation underscores the ruling’s narrow applicability, restricting its use to the specific facts presented.

Implications for Taxpayers and Advisors

The IRS’s narrow ruling in PLR-101721-26 underscores the perils of funding agreements that inadvertently create a second class of stock under § 1361(b)(1)(D), which prohibits S corporations from having more than one class of stock unless the differences are limited to voting rights. The ruling’s non-precedential status under § 6110(k)(3) means it cannot be cited as authority in other cases, but it offers a window into the IRS’s current enforcement priorities. Taxpayers and advisors must treat this as a cautionary tale rather than a safe harbor.

Funding agreements—particularly convertible debt, SAFEs, or preferred stock—pose the highest risk of triggering an inadvertent termination of S corporation status. The IRS has consistently held in recent guidance, such as CCA 202212010, that even minor deviations in economic rights can violate the single-class rule, rendering the corporation ineligible for S status. Advisors should scrutinize these instruments to ensure they do not function as de facto equity with disproportionate rights. For example, a SAFE that converts into shares with different liquidation preferences or a convertible note with a fixed dividend could inadvertently create a second class of stock, as seen in IRS Letter Ruling 202312001.

Monitoring compliance with S corporation requirements is not optional but a continuous obligation. The IRS’s decision in T.C. Memo. 2021-12 demonstrates that delays in correcting violations—even those caused by unintentional errors—can disqualify a corporation from relief under § 1362(f), which permits waivers for inadvertent terminations. Taxpayers must act promptly upon discovering a violation, whether it involves an ineligible shareholder, a prohibited class of stock, or a failed QSub election. The IRS’s requirement in Treas. Reg. § 1.1362-4(a) that corporations file a written request for relief, detailing the error and corrective steps, means that proactive monitoring is the only way to avoid irreversible tax consequences.

Relief under § 1362(f) remains available, but it is not guaranteed. The IRS’s grant of relief in IRS Letter Ruling 202301001 hinged on the taxpayer’s ability to demonstrate that the error was unintentional and corrected within a reasonable timeframe. Taxpayers should document every step taken to rectify a violation, including redeeming noncompliant stock or amending shareholder agreements, to strengthen their case for relief. Advisors should also be aware that the IRS’s Rev. Proc. 2022-19 provides automatic relief for certain minor violations, such as late S election filings, but this does not extend to structural issues like a second class of stock.

Reorganizations involving S corporations and QSubs require meticulous structuring to avoid unintended terminations. The IRS’s clarification in Rev. Rul. 2008-18 that a QSub election terminates if the parent S corporation loses its status underscores the fragility of QSub elections in transactions. Advisors must ensure that reorganizations under § 368(a)(1)(F) or other provisions preserve the parent’s S status and that QSub elections are re-filed if necessary. The IRS’s refusal in PLR-101721-26 to opine on the validity of the reorganization highlights the need for pre-transaction planning to avoid reliance on post-facto rulings.

While this ruling is non-precedential, its practical takeaways are clear: funding agreements must be drafted with extreme care, compliance must be monitored in real time, and relief under § 1362(f) is a last resort, not a safety net. Advisors should treat this ruling as a reminder that the IRS’s scrutiny of S corporation eligibility is intensifying, and that proactive due diligence is the only way to mitigate risk.
