IRS Grants Extension for Late §336(e) Election in S Corporation Stock Sale

IRS Allows Late Election to Treat S Corporation Stock Sale as Asset Sale

In a rare and narrowly tailored decision, the IRS granted a private letter ruling (PLR-114045-25) allowing a taxpayer to retroactively elect under §336(e) to treat a stock sale as an asset sale, despite missing the regulatory deadline. The taxpayer requested §9100 relief—a discretionary extension under §301.9100-3—to file a late §336(e) election, which would recharacterize the sale of S Corporation Target’s stock as a deemed asset sale for federal income tax purposes. The stakes were high: without the election, the transaction would trigger immediate capital gains tax for the seller and deny the purchaser a stepped-up basis in the target’s assets. The IRS’s decision, while granting relief, underscores the strict standards for such relief and the non-precedential nature of PLRs.

The Taxpayer's Dilemma: A Late Election with High Stakes

On Date 1, individuals acting as Purchasers acquired all outstanding stock of S Corporation Target from Shareholder in a transaction represented as a qualified stock disposition (QSD) under §1.336-1(b)(6). The parties structured the deal with the intent to treat the stock sale as an asset sale for federal income tax purposes, leveraging the potential benefits of a §336(e) election—a provision allowing certain stock dispositions to be treated as deemed asset sales. However, despite their intent, the parties failed to timely file the §336(e) election or execute the required Agreement by the statutory deadline.

The stakes were immediate and severe. Without the election, the transaction would be taxed as a stock sale, triggering capital gains tax for Shareholder on the sale proceeds. Meanwhile, the Purchasers would inherit the Target’s carryover tax basis in its assets—limiting future depreciation and amortization deductions. Conversely, a valid §336(e) election would recharacterize the transaction as an asset sale, allowing the Purchasers to obtain a stepped-up basis in the Target’s assets while potentially subjecting Shareholder to ordinary income treatment on certain asset categories (e.g., inventory, receivables) and exposing the Target to built-in gains tax if it had previously been a C corporation.

Faced with the missed deadline, the parties sought §9100 relief under §301.9100-3, requesting an extension of time to file the late election and Agreement. The request carried significant risk: if denied, the transaction would be locked into its default tax treatment, with no recourse to reverse the consequences.

The §336(e) Election: A Timely Requirement with Strict Deadlines

The §336(e) election allows corporate sellers to treat a stock sale as an asset sale for tax purposes, avoiding double taxation on corporate-level gains. This election is governed by strict timing and procedural rules under Treasury Regulation §1.336-2(h)(3), which require precise compliance to avoid default tax treatment.

A qualified stock disposition (QSD) under §1.336-1(b)(6) is the transaction that triggers eligibility for the §336(e) election. To qualify as a QSD, the sale, exchange, or distribution of stock must meet three core requirements: (1) the seller must own at least 80% of the target corporation’s voting power and value immediately before the disposition, (2) the seller must lose control (ownership drops below 80%) as a result of the transaction, and (3) the disposition must be taxable (not part of a tax-free reorganization under §368). The election cannot apply if the transaction is already subject to a §338(h)(10) election.

For the election to be valid, the seller must satisfy three procedural requirements under §1.336-2(h)(3). First, all shareholders of the S corporation target—including those who do not dispose of stock—must enter into a written, binding agreement with the S corporation on or before the due date (including extensions) of the target’s federal income tax return for the year of the disposition. Second, the S corporation must retain a copy of this agreement. Third, the S corporation must attach a §336(e) election statement to its timely filed (including extensions) federal income tax return for the same tax year. The election statement must include specific information, such as the names and EINs of the parties, the date of the QSD, and a declaration that the election is being made under §336(e).

Failure to meet these requirements results in the transaction being treated as a standard stock sale, with no asset sale treatment. This means the seller recognizes capital gain or loss based on the difference between the sale price and its tax basis in the stock—not the underlying assets. For the purchaser, the target’s assets retain their historic tax basis, eliminating the potential step-up in basis that would have been available had the election been properly made. In the case of an S corporation that was previously a C corporation, this default treatment also exposes the target to built-in gains tax under §1374 if appreciated assets are sold within the recognition period.

§9100 Relief: The IRS's Discretion to Grant Extensions

The IRS’s authority to grant extensions for regulatory elections stems from §301.9100-3, which permits discretionary relief when a taxpayer fails to make a regulatory election within the prescribed deadline. Unlike statutory elections—which are explicitly authorized by statute and subject to stricter rules—regulatory elections derive their authority from Treasury regulations. The scope of §9100 relief is broad in theory but narrow in practice, as it applies only to elections where the IRS has delegated authority to set deadlines through regulation.

To qualify for relief under §301.9100-3, the taxpayer must demonstrate three conditions: first, that the failure to act was the result of reasonable action taken in good faith, such as reliance on professional advice or a genuine misunderstanding of the law; second, that the request for relief was filed promptly upon discovery of the error; and third, that granting the extension would not prejudice the interests of the government. The IRS interprets "no prejudice" strictly, meaning the government must retain the ability to assess and collect tax without administrative burden or loss of revenue. In the context of the PLR, the parties argued that their delay resulted from a miscommunication between advisors, that the election was filed before the IRS discovered the error, and that the government’s interests remained intact since the statute of limitations had not expired.

The IRS evaluates these conditions through representations and affidavits submitted by the taxpayer, tax professionals, and company officials. These documents must provide a detailed factual narrative explaining the circumstances of the failure, the steps taken to comply, and the reasons why relief should be granted. The IRS does not grant such relief lightly; its general reluctance stems from the need to maintain uniformity in tax administration and prevent taxpayers from exploiting procedural errors to avoid tax liability. However, when the record shows clear evidence of reasonable cause and no harm to the government, the IRS may exercise its discretion to extend the deadline. In this case, the parties submitted sworn statements and representations to establish that their actions met these stringent requirements.

IRS Grants Relief: The Rationale Behind the Decision

The IRS concluded that the parties acted reasonably and in good faith, that granting relief would not prejudice the government’s interests, and that the requirements of §§301.9100-1 and 301.9100-3 were satisfied. Under §301.9100-3, the IRS may extend a regulatory deadline when the taxpayer demonstrates reasonable cause and the government’s interests remain unaffected. Here, the parties submitted sworn statements and representations establishing that their delay in making the §336(e) election was not willful, that they acted promptly upon discovery of the error, and that the government retained full ability to assess and collect any tax owed.

The relief granted is narrowly conditioned. The parties have 60 days from the date of this letter to enter into a written, binding agreement under §1.336-2(h)(3)(i) and for the S Corporation Target to file the Election Statement under §1.336-2(h)(3)(iii), attaching it to its tax return for the year of the transaction. A copy of this letter—or a statement referencing its control number (PLR-114045-25)—must accompany the return. Within 120 days of this letter, all relevant parties must file or amend returns to reflect the election for the year of the transaction and any affected years. The relief is further conditioned on the parties’ aggregate tax liabilities not being lower than they would have been had the election been timely made, taking into account the time value of money.

The IRS emphasized that it relied on the parties’ representations in granting relief but cautioned that the Director’s office must verify all essential facts during audit. No opinion was expressed regarding the taxpayers’ tax liabilities, the qualification of the transaction as a “qualified stock disposition,” or any other tax consequences arising from the election or its late filing. The ruling is non-precedential under §6110(k)(3) and applies only to the requesting taxpayers. Penalties and interest, if applicable, remain unaffected by this relief.

Implications: What This Ruling Means for Taxpayers and Advisors

This ruling underscores the narrow applicability of late §336(e) election relief under §9100, serving as a cautionary tale rather than a precedent-setting precedent. Because the PLR is non-precedential under §6110(k)(3) and applies only to the requesting taxpayers, it offers no binding authority for other cases. Taxpayers and advisors must recognize that §9100 relief remains a rare and discretionary remedy, granted only when the IRS determines no prejudice to government interests exists—a determination that hinges on meticulous documentation and factual verification during audit.

The decision also highlights the critical importance of timely elections. Missing the §336(e) filing deadline—even by a single day—can expose taxpayers to penalties and interest, as the ruling explicitly notes that such liabilities remain unaffected by relief. This underscores the risks of relying on §9100 relief as a fallback, particularly given the IRS’s stringent requirements for reasonable cause and the potential for statute-of-limitations issues to derail relief requests. Advisors should counsel clients to treat regulatory deadlines as absolute, documenting every step of the election process to preemptively support any future relief requests.

For transactions involving S corporations, the ruling carries additional weight. While §336(e) elections are often used in M&A to achieve a step-up in asset basis, the implications for S corps—particularly those with former C corporation assets subject to the built-in gains tax under §1374—can be complex. Taxpayers must weigh the benefits of a stepped-up basis against potential BIG tax liabilities and shareholder-level tax consequences. The IRS’s emphasis on verifying "essential facts" during audit further signals that thorough due diligence—including representations about the transaction’s structure and tax consequences—is essential when seeking relief.

Finally, the ruling serves as a reminder of the IRS’s broad discretion in granting §9100 relief. The agency’s willingness to approve relief in this case does not signal a shift toward leniency; rather, it reflects the specific facts presented. Taxpayers and advisors should approach late elections with extreme caution, recognizing that §9100 relief is a last resort, not a standard compliance tool. The broader context of §336(e) elections in M&A transactions remains unchanged: strict adherence to deadlines and meticulous recordkeeping are the surest paths to avoiding costly missteps.
