IRS Denies Late Mark-to-Market Election for Corporation Due to Hindsight and Lack of Good Faith

Corporation’s $5M Gamble: IRS Rejects Late Mark-to-Market Election Due to Hindsight

A corporation’s attempt to retroactively claim $5 million in securities trading losses under the mark-to-market accounting method was rejected by the IRS, which ruled the taxpayer acted with impermissible hindsight. The IRS denied the corporation’s request for a late election under Section 475(f)(1)—which allows qualifying securities traders to treat gains and losses as ordinary income rather than capital—finding the taxpayer failed to demonstrate good faith in its delayed awareness of the election’s tax benefits. The core issue hinged on the corporation’s strategic timing: it sought to apply the election retroactively only after realizing the magnitude of its losses, thereby exploiting the advantage of hindsight to offset taxable income. The IRS’s denial underscores the agency’s strict enforcement of election deadlines, particularly where taxpayers appear to leverage procedural gaps for tax planning purposes.

The Timeline: How a Corporation’s Securities Trading Losses Snowballed

Executive, the controlling shareholder and CEO of the taxpayer corporation, initiated securities trading activities on behalf of the taxpayer on Date 1, deploying approximately $d—roughly e percent of the corporation’s cash balance at the time—into the market. Executive, leveraging personal experience in securities trading, sought higher returns than passive deposits would yield. The taxpayer’s tax function remained informal until Month 1, when the Tax Director was hired as the internal head of tax matters. Lacking expertise in securities trading tax issues, the Tax Director relied on Accounting Firm A, which had long provided financial audit and tax advisory services to the taxpayer.

On Date 2, the Tax Director met with Tax Advisor, a CPA and tax partner at Accounting Firm A with over e years of experience advising companies in technology, consumer products, and retail. They discussed the taxpayer’s overall tax needs, including the tax implications of its securities trading activities. A follow-up meeting on Date 3 focused specifically on trading volume and frequency, with the Tax Director disclosing details about Executive’s trading activities. Neither Executive nor the Tax Director was aware at the time of the § 475(f)(1) election, which allows qualifying securities traders to use the mark-to-market method of accounting—treating securities as sold at fair market value on the last business day of the tax year, recognizing gains or losses as ordinary income or loss. The Tax Advisor did not mention the election during these discussions.

From Date 1 through Year 2, the taxpayer’s securities trading generated gains, with trading volume increasing over time. However, by Month 2 of Year 2, the tide turned: the taxpayer began incurring substantial losses from its trading activities. Between Date 4 and Date 7, even after accounting for both realized and unrealized gains and losses, the taxpayer faced sizeable net trading losses. Trading continued actively through Date 9, with positions in stocks and options triggering § 1091(a) wash sale rules at times—prohibiting loss deductions when substantially identical securities are repurchased within 30 days.

As losses mounted, the Tax Director communicated the deteriorating situation to the Tax Advisor on multiple occasions. In an email sent on Date 6, the Tax Director inquired about carrying back capital losses to Year 1 under § 165(i), which permits a three-year carryback for certain disaster-related losses. The Tax Advisor responded the same day with detailed guidance on § 165(i) but did not mention the possibility of making a timely § 475(f)(1) election for Year 2.

The taxpayer asserts that it was not informed of the availability of the § 475(f)(1) election until Date 8, the year following Year 2, when Tax Partner, a CPA and senior tax partner at Accounting Firm B, provided occasional international tax advice to the taxpayer, advised of the election’s existence. Following this belated discovery, the taxpayer engaged Accounting Firm B to pursue relief under § 301.9100-3 for a late § 475(f)(1) election. However, the private letter ruling request was not filed with the IRS until Date 11—more than f months after the Tax Partner’s advice and g months after the original election deadline for Year 2.

The taxpayer attributes the delay in seeking relief to the COVID-19 global pandemic, which disrupted internal and external communications. It claims that stay-at-home orders and business disruptions halted in-person meetings, impeded internal coordination among tax staff, and severely limited the Tax Director’s ability to consult with external advisors. The taxpayer maintains that these pandemic-related obstacles prevented timely awareness of the election and hindered the filing of the required relief request.

The Dispute: Taxpayer’s Ignorance vs. IRS’s Hindsight Argument

The taxpayer framed its failure to file a timely § 475(f)(1) election as a product of inadequate advice and pandemic disruptions, arguing that it remained unaware of the election’s availability until Date 8—nearly a year after the Year 2 taxable year’s filing deadline. It claimed the COVID-19 pandemic compounded these issues by halting in-person meetings, stalling internal coordination, and severing external communications with its tax advisor, Tax Partner at Accounting Firm B. The taxpayer emphasized that its decision to seek relief was not driven by hindsight, as the election would have been advantageous at any time, given that corporate capital gains rates did not differ materially from ordinary income rates.

The IRS rejected this narrative, asserting that the taxpayer’s delay in filing the election until after reviewing its trading results demonstrated hindsight. In the IRS’s view, the taxpayer waited to assess its Year 2 losses before pursuing relief, undermining its claim of ignorance. The agency also dismissed the pandemic’s impact as insufficient justification, noting that stay-at-home orders did not preclude the taxpayer from researching the election or communicating with advisors remotely. Crucially, the IRS pointed out that the taxpayer failed to provide concrete evidence—such as contemporaneous records or expert testimony—proving that its decision lacked hindsight. Without such proof, the IRS concluded, the taxpayer’s arguments amounted to post-hoc rationalization rather than a legitimate basis for relief.

IRS’s Legal Gauntlet: Why the Late Election Failed Under § 301.9100-3

The IRS denied relief under § 301.9100-3 for the taxpayer’s late § 475(f)(1) election on two grounds: the taxpayer failed to act reasonably and in good faith, and granting relief would prejudice the government’s interests. The denial hinged on the taxpayer’s inability to rebut the presumption of hindsight under § 301.9100-3(b)(3)(iii) and the mandatory prejudice rule for accounting method elections requiring a § 481(a) adjustment under § 301.9100-3(c)(2)(ii).

(a) Taxpayer did not act reasonably and in good faith

Section 301.9100-3(b)(3)(iii) presumes a taxpayer did not act reasonably and in good faith if specific facts changed after the election’s due date to make the election advantageous, unless the taxpayer provides strong proof that its decision did not involve hindsight. The IRS applied this rule strictly, finding the taxpayer’s continued trading activities and delayed filing created an insurmountable hindsight advantage. The taxpayer filed its late election over six months after the due date, during which it could assess the results of its securities trading and core business operations. Unlike the taxpayer in Vines v. Commissioner, who filed within two months and ceased trading, this taxpayer engaged in ongoing trading activities, allowing it to determine whether the election would yield tax benefits based on realized losses. The IRS rejected the taxpayer’s argument that the lack of a corporate capital gains rate differential negated hindsight, noting that corporations still benefit from accelerating losses to offset ordinary income, particularly when trading results are known. The IRS also cited Acar v. United States, Knish v. Commissioner, and Kholi v. Commissioner, where courts denied relief for late § 475(f) elections filed months or years after the due date, emphasizing that continued trading and knowledge of financial results constituted classic hindsight-driven decisions.

(b) Granting relief would prejudice the interests of the government

Under § 301.9100-3(c)(2)(ii), the government’s interests are deemed prejudiced if an accounting method regulatory election requires a § 481(a) adjustment, unless unusual and compelling circumstances exist. The IRS found no such circumstances here. The § 475(f)(1) election would have triggered a § 481(a) adjustment to account for unrealized gains or losses in securities held at the beginning of the election year, altering the taxpayer’s tax liability across multiple years. The IRS rejected the taxpayer’s pandemic-related arguments, noting that stay-at-home orders did not preclude remote research or advisor consultations. The IRS emphasized that millions of taxpayers adapted to remote work during the pandemic, and the taxpayer failed to demonstrate concrete impediments to timely filing. Without unusual and compelling circumstances, the IRS concluded that granting relief would prejudice the government by allowing the taxpayer to retroactively alter its tax liability based on known outcomes.

The Bottom Line: What This Ruling Means for Traders and Advisors

The IRS’s denial of the taxpayer’s late § 475(f)(1) election under § 301.9100-3 underscores the critical importance of timely filing regulatory elections, particularly for securities traders seeking mark-to-market accounting. Section 475(f)(1) allows qualifying traders to treat securities as sold at year-end fair market value, converting capital gains and losses into ordinary income—an advantage that requires strict compliance with election deadlines. The IRS’s refusal to grant relief in this case highlights the high bar for demonstrating good faith under § 301.9100-3, where even pandemic-related disruptions failed to meet the threshold for "unusual and compelling circumstances."

Tax advisors must prioritize proactive election management, ensuring clients are aware of deadlines and the irreversible nature of § 475(f)(1) elections. The IRS’s skepticism toward pandemic-related excuses—even in cases where remote work was feasible—signals a broader trend of strict enforcement of election rules. Relief under § 301.9100-3 remains limited, with the 6-month automatic extension serving as the primary safeguard for late filers. For traders and their advisors, this ruling serves as a cautionary tale: hindsight-driven decisions carry significant tax risk, and the IRS will not tolerate retroactive adjustments absent extraordinary justification.

While this private letter ruling (PLR) is non-precedential, it may signal the IRS’s evolving stance on late elections and trader status. Similar cases are likely to arise as the IRS continues to scrutinize securities trading activities, particularly in the wake of increased cryptocurrency trading and high-frequency strategies. Taxpayers and advisors should anticipate further guidance—or litigation—clarifying the boundaries of § 475(f)(1) eligibility and the limits of relief under § 301.9100-3.
