IRS Grants Extension for Late Section 336(e) Election in S Corporation Stock Disposition

IRS Allows Late §336(e) Election: A Lifeline for S Corporation Shareholders

The IRS granted a non-precedential extension under §301.9100-3 to an S corporation’s shareholders and purchaser, permitting a late §336(e) election after missing the original deadline tied to the target’s tax return due date. Section 336(e) allows certain stock dispositions to be treated as asset sales for tax purposes, avoiding the tax inefficiencies of a stock sale. The relief came with strict conditions: the parties had 60 days from the ruling date to execute the required agreement and 120 days to amend their tax returns.

The Taxpayer's Dilemma: Why the §336(e) Election Was Missed

On Date 1, an individual purchaser acquired all the stock of S Corporation Target from its shareholder in a transaction later represented to qualify as a qualified stock disposition under §1.336-1(b)(6). A §336(e) election—which permits certain stock dispositions to be treated as asset sales for tax purposes—was required to be made by the due date (including extensions) of the target’s federal income tax return for the taxable year that included the disposition date. However, no timely election was filed.

The parties subsequently submitted a request for relief under §301.9100-3, seeking an extension of time to enter into the required agreement and file the election statement. In their representations, the parties, company officials, and tax professional explained that the failure to timely comply arose from a combination of administrative oversight and miscommunication among the parties’ advisors. They further attested that the request for relief was filed before the IRS had discovered the missed deadline, and that none of the parties sought to alter a return position subject to an accuracy-related penalty under §6662.

The IRS's Rationale: Good Faith and No Prejudice to the Government

The IRS granted the extension under its discretionary authority under §301.9100-3, which permits relief for late regulatory or statutory elections when the taxpayer demonstrates reasonable cause, good faith, and no prejudice to the government. Section 301.9100-3(a) explicitly requires that the Commissioner be satisfied the taxpayer acted reasonably and in good faith, and that granting relief would not prejudice the government’s interests.

The parties satisfied these requirements through sworn affidavits and representations explaining that the failure arose from administrative oversight and miscommunication among advisors—circumstances the IRS has historically recognized as reasonable cause. The request was filed before the IRS had initiated any examination or discovered the missed deadline, eliminating any risk of altered return positions or penalties under §6662. Critically, the IRS confirmed that granting relief would not result in tax liabilities lower than if the election had been timely made, a core condition of §301.9100-3 relief.

The Conditions: 60 Days to Comply, 120 Days to Amend Returns

The IRS imposed strict conditions for granting relief under §301.9100-3, which allows late elections when the taxpayer demonstrates reasonable cause. To comply, the S Corporation Target and Shareholder must enter into a written, binding agreement under §1.336-2(h)(3)(i) and file the Election Statement under §1.336-2(h)(3)(iii) within 60 days of the PLR’s date. The Election Statement must be attached to the S Corporation Target’s tax return for the taxable year including the transaction date. If filing electronically, the taxpayer may satisfy this requirement by attaching a statement to the return that includes the PLR’s date and control number (PLR-116212-25).

Additionally, the IRS required that a copy of the PLR itself be attached to the tax return. Within 120 days of the PLR’s date, all relevant parties must file or amend returns to report the transaction consistently with the §336(e) election for the taxable year in which the transaction occurred and any affected years. This deadline ensures that the election’s tax consequences are reflected in the correct reporting periods.

Crucially, the extension is conditioned on the aggregate tax liabilities for all years affected by the election not being lower than they would have been if the election had been timely made. The IRS explicitly noted that this condition accounts for the time value of money, meaning any tax deferral benefits from a late election are disallowed. While the IRS confirmed that granting relief would not result in lower tax liabilities, it expressed no opinion on the actual tax liabilities for the years involved, leaving open potential disputes over valuation or basis allocation. Taxpayers must therefore ensure their amended returns reflect the election’s full tax impact without understating liabilities.

What’s Off the Table: IRS Expresses No Opinion on Key Issues

The IRS declined to opine on three critical interpretive gaps in the late §336(e) election ruling. First, it expressed no opinion on whether the stock disposition qualified as a “qualified stock disposition” under §1.336-1(b)(6), leaving open the possibility that the transaction might not meet the 80% vote-and-value threshold or the 12-month window. Second, the agency reserved judgment on all other tax consequences arising from the §336(e) election itself, including the allocation of basis, the recognition of gain or loss, and the impact on the target’s earnings and profits—issues that could trigger disputes over valuation or character of income. Third, the IRS declined to address the tax consequences of making the election late under any other Code section, such as potential penalties under §6651 for failure to file or accuracy-related penalties under §6662, or the interplay with state tax regimes that do not conform to federal relief provisions.

The ruling’s silence underscores its non-precedential nature—it binds only the requesting taxpayer and offers no safe harbor for similar fact patterns. Even with relief granted under §301.9100-3, penalties and interest continue to accrue from the original due date, as the IRS made clear that granting relief does not waive statutory interest under §6601. Taxpayers seeking certainty on these unresolved issues must either secure a private letter ruling with broader scope or face the risk of future examinations and potential disputes.

Implications for S Corporations: A Cautionary Tale and a Path Forward

The IRS’s late-election relief under §301.9100-3 offers a lifeline for S corporations and their shareholders who miss the §336(e) election deadline, but it comes with critical caveats. Taxpayers must act within 12 months of the original due date to file a late election, demonstrating reasonable cause—such as advisor error or miscommunication—and proving no tax avoidance motive. Even with relief granted, interest continues to accrue under §6601 from the original due date, as the IRS explicitly clarified that relief does not waive statutory interest. Penalties for late elections, including the 5% per month failure-to-file penalty under §6651, remain a risk if relief is denied or the 12-month window lapses.

This ruling underscores the perils of missed deadlines in stock dispositions, where a qualified stock disposition (QSD)—defined under Treas. Reg. §1.336-1(b)(6) as the sale of ≥80% of a corporation’s stock within 12 months—can trigger unintended tax consequences if an §336(e) election is overlooked. For S corporations, the stakes are particularly high: a deemed asset sale under §336(e) may accelerate gain recognition that flows through to shareholders under §1366, while also potentially triggering the 21% built-in gains tax (BIG tax) under §1374 if the S corporation was previously a C corporation. The ruling serves as a reminder that §336(e) is not a one-size-fits-all tool—taxpayers must weigh its benefits against alternatives like a stock sale or the §338(h)(10) election, which requires a corporate buyer.

The non-precedential nature of this PLR—binding only the requesting taxpayer—highlights the need for broader certainty. Taxpayers facing similar fact patterns must either secure their own PLR or risk future examinations and disputes. The IRS’s silence on unresolved issues, such as the interplay between §336(e) and passive investment income (PII) rules under §1362(d)(3), leaves room for ambiguity. S corporations in industries with high PII or AE&P balances should proceed with caution, as excessive PII could jeopardize their S status.

For the broader M&A landscape, this ruling signals that the IRS remains open to granting relief for late elections when taxpayers act in good faith, but it does not signal a relaxation of enforcement. The 60-day compliance window and 120-day amended return requirement outlined in the ruling suggest that taxpayers should proactively monitor election deadlines and document reasonable cause for any delays. In an era where stock dispositions are increasingly complex—particularly in private equity carve-outs or family-owned S corporations—this PLR serves as both a cautionary tale and a strategic guide for navigating the tightrope of tax elections.
