Marijuana Mogul, Pot Growth Firm Challenge $7.8 Million in Taxes

The Petitions

Two separate petitions filed Wednesday contest IRS deficiency notices totaling $7.8 million across multiple tax years. Court records identify the petitioners as a named cannabis executive and a cultivation-focused entity, though the filings don't disclose the specific tax years under audit or the breakdown of the contested amounts between the two parties. Both cases have been assigned to the U.S. Tax Court's regular docket.

The timing aligns with a broader uptick in 280E litigation. More than 30 cannabis tax cases have reached federal dockets since 2024, according to CannIntel's tracking. The median deficiency in cases that disclose amounts: $2.1 million.

280E Exposure for Cultivation Operators

Cultivation businesses face particularly brutal 280E math because cost of goods sold represents their only allowable deduction. Growers can capitalize direct cultivation costs—nutrients, labor, utilities tied to grow rooms—but can't deduct post-harvest expenses such as packaging, distribution, compliance testing, or general administrative overhead. The result? Effective tax rates routinely exceed 70% of gross profit.

One West Coast MSO disclosed in a 2025 10-K that its cultivation segment paid an average effective rate of 74% under 280E, compared to 38% for its retail operations. That delta explains why vertically integrated operators increasingly allocate revenue and margin to downstream segments through transfer-pricing strategies—a practice the IRS has begun scrutinizing more aggressively.

The Bull Case and the Bear Case

For the petitioners, the bull case hinges on carve-outs and cost-capitalization disputes that have occasionally succeeded in Tax Court. In Patients Mutual Assistance Collective Corp. v. Commissioner (2015), the court allowed a California dispensary to deduct caregiving services as a separate trade or business. In Alterman v. Commissioner (2018), a Colorado grower successfully capitalized a broader set of indirect costs into COGS, reducing taxable income by $340,000.

The bear case is harder to argue with: the IRS wins roughly 80% of litigated 280E disputes, and cultivation cases offer fewer carve-out opportunities than retail or ancillary-service models.

Settlement remains the most common outcome. Of the 22 cannabis tax cases resolved since 2023, 16 settled before trial, according to Tax Court records reviewed by CannIntel.

Investor Implications

Public cannabis companies carry 280E contingent liabilities that rarely surface until an audit letter arrives. Trulieve disclosed a $47 million reserve for uncertain tax positions in its Q2 2026 10-Q, most of it tied to 280E exposure. Curaleaf's reserve: $62 million. These aren't hypothetical. They represent management's estimate of probable cash outflows if the IRS prevails in pending or anticipated disputes.

The risk cuts both ways. A landmark taxpayer win in Tax Court could trigger reserve releases across the sector, flowing straight to net income. An IRS victory with new precedent on cost capitalization could force operators to restate prior years and book additional liabilities.

The Rescheduling Variable

DEA's proposed rescheduling of cannabis to Schedule III would eliminate 280E exposure prospectively, but it does nothing for prior tax years. The proposed rule, published in the Federal Register on May 16, 2024, remains under review following a public comment period that closed in July 2024. No final rule has been issued.

Even if rescheduling takes effect in 2027, the IRS retains authority to audit tax years 2021 through 2026 under the standard three-year statute of limitations (six years if the agency alleges substantial understatement). That means 280E litigation will persist well into the next decade regardless of rescheduling outcomes. For operators with trailing exposure, settlement or litigation are the only paths to resolution.

What Comes Next

The cases will proceed through Tax Court's standard pre-trial schedule: initial conference, discovery, possible summary judgment motions, and trial or settlement. Median time from petition to resolution in cannabis tax cases: 18 months, based on CannIntel analysis of closed dockets since 2020. Parties typically exchange initial disclosures within 60 days and complete fact discovery within nine months.

The Tax Court doesn't publish petitions or deficiency notices, so the specific legal theories and factual disputes underlying the $7.8 million assessment remain undisclosed. Both cases are publicly docketed and will generate additional filings as they move forward.

The Kicker

We'll be watching for three signals: whether either petitioner files a motion for summary judgment on a novel COGS theory, whether the IRS moves to consolidate the cases, and whether settlement talks surface in status reports. Next docket entries are due within 90 days.
