Prepared for the named operator under a limited-scope diagnostic engagement. This example is illustrative and does not constitute tax or legal advice to any reader; no client relationship is created by viewing it. A real §280E Risk Review is delivered in writing by a credentialed Enrolled Agent and is not a signed return, a filed refund claim, or an audit defense — those are scoped and engaged separately under an engagement letter and, where representation is involved, a Form 2848. Federal cannabis scheduling and IRS guidance are changing rapidly in 2026; positions are verified against current authority before any return is signed.

02 · Executive Summary

What the numbers say, in one paragraph

Northgate runs a mixed medical/adult-use cultivation business in California alongside a small adult-use retail license and a non-plant-touching holding entity. On the figures provided, the operating cultivation entity carries a thin cost-of-goods-sold position and a medical-versus-adult-use allocation with no square-footage support — together the largest recoverable exposure. Cash-reporting hygiene under §6050I and Schedule III transition readiness are live but secondary. No active IRS matter was reported, so audit-defense, trust-fund, and collections work are monitored rather than engaged.

Key exposure — illustrative

An under-absorbed COGS method appears to be inflating the §280E disallowance on the order of $60,000–$150,000 per year, with a further $25,000–$70,000 tied to the unsupported medical/adult-use allocation. Controlling authority is flagged below; these are illustrations of the mechanism, not conclusions, and are confirmed only against real books.

03 · Facts

The situation as presented

Facts below are as reported by the operator for the diagnostic and are illustrative. They are not independently verified in a $375 diagnostic; verification is part of any downstream engagement.

Business overview

A boutique California grow — roughly 10,000 sq ft of canopy and on the order of $620,000 in annual gross receipts — operating from a single location. Cultivation and retail sit in separate licensed entities; a third entity holds the real estate and brand IP and touches no plant.

License posture detail

The operating entity holds both a medical and an adult-use cultivation designation (Mixed). A separate adult-use microbusiness license covers retail. Both licensed entities are plant-touching and therefore within the reach of §280E; the holding entity is ancillary and non-plant-touching, and on these facts sits outside §280E's scope. §280E is not asserted uniformly across the group — it is applied to the trade or business that traffics, entity by entity.

Revenue streams

  • Bulk flower — adult-use channel (majority of receipts)
  • Medical flower — medical channel
  • Trim / biomass sold to manufacturers
  • Intercompany rent to the holding entity (non-cannabis, ancillary)

Cash profile

Cash-intensive, as is typical for the segment: a meaningful share of receipts arrive as cash, including individual receipts above $10,000. Books are reconstructed from POS, Metrc, and bank records; the reconciliation is partial, and Form 8300 filing history is incomplete on the records provided.

04 · Analysis

Reading the exposure

§280E exposure summary

IRC §280E denies deductions and credits to a trade or business that consists of trafficking in Schedule I or Schedule II controlled substances. Cannabis remains a Schedule I substance federally, so ordinary operating deductions of the plant-touching entities are disallowed. What survives is cost of goods sold — a return of capital, not a deduction — so the entire game is how much legitimate production cost is defensibly captured in COGS.

COGS defensibility snapshot

As a producer (cultivator), Northgate's inventoriable costs are governed by the full-absorption method of Treas. Reg. §1.471-11(c). The COGS as presented appears to exclude several categories of indirect production cost that §1.471-11(c) allows a producer to absorb into inventory — the single most common way a grow overpays under §280E. This is a §471-11 costing question and is distinct from the small-business §471(c) method election, which is addressed separately in the return-disclosure workflow.

Cash / §6050I exposure

A person who receives more than $10,000 in cash in a trade or business must report it on Form 8300 under IRC §6050I. The records provided suggest filings may be missing or late. Penalties apply per unfiled or late report, and the exposure escalates sharply where the failure is treated as intentional disregard.

Payroll / §6672 exposure

Employment-tax deposits appear current on the facts provided. Flagged for completeness: where trust-fund taxes are withheld and not paid over, responsible persons face the trust fund recovery penalty under IRC §6672. On these facts the exposure reads low and is monitored, not engaged.

Collections / lien exposure

No assessed federal balance was reported. Absent an assessed liability, the federal tax lien under IRC §6321 and levy under IRC §6331 machinery is not engaged. Monitored so that any new assessment is caught before enforced collection begins.

Transition-window posture — Schedule III readiness

§280E reaches only Schedule I and Schedule II substances. If cannabis is rescheduled to Schedule III, §280E would cease to apply to the cannabis trade or business going forward — the single largest change on Northgate's horizon. The transition window is the period around that change, and it is where a mixed operator gains or loses the most.

Position now: (1) maximize defensible COGS under Treas. Reg. §1.471-11(c) while §280E still bites; (2) prepare the books to deduct ordinary operating expenses on a go-forward basis the moment rescheduling is effective; (3) evaluate — carefully — whether prior-year §471 corrections support a defensible amended return, noting that retroactive relief is contested and the IRS is pushing back. This posture is why the diagnostic routes to Transition Planning first.
