§471-11 / §280E COGS Review & Adjustment Memo

More cost belongs in COGS — defensibly

Under §280E, only cost of goods sold survives for Northgate's plant-touching entities, so the entire recoverable position is how much legitimate production cost is captured in COGS. The cultivation entity is a producer and may absorb a full range of indirect production costs under Treas. Reg. §1.471-11 — costs it is currently leaving on the deduction side, where §280E disallows them. The recomputation moves those costs into COGS, applies a defensible medical/adult-use allocation, and leaves a clean audit trail.

The operation and its costs

Facts below are as reported by the operator and are illustrative; they are verified during the engagement.

Client summary

A boutique California grow — roughly 10,000 sq ft of canopy, about $620,000 in annual gross receipts — with both medical and adult-use cultivation designations and an adult-use retail license. Cultivation is a producer; retail is a reseller; the two are governed by different COGS rules.

Business lines

• Cultivation — plant-touching producer; full-absorption COGS under §1.471-11.
• Retail — plant-touching reseller; limited COGS (invoice + freight-in) under §1.471-3.
• Holding — ancillary, non-plant-touching; ordinary deductions allowed (separate trade or business).

Revenue streams

Bulk adult-use flower (majority), medical flower, and trim/biomass from cultivation; retail counter sales; intercompany rent to the holding entity. The medical and adult-use split drives the allocation study.

Cost structure

Direct production costs (seeds/clones, grow labor, nutrients) are captured; the gaps are indirect production costs — cultivation facility rent and utilities, indirect labor, depreciation on grow equipment, quality control, and supervisory time — that §1.471-11 permits a producer to absorb but that Northgate currently expenses (and therefore forfeits under §280E).

The costing method, step by step

COGS methodology (§471-11(c))

As a producer, Northgate Cultivation applies the full-absorption method of Treas. Reg. §1.471-11. Under §1.471-11(c)(2), indirect production costs fall in three buckets: category 1 costs that must be inventoried, category 3 costs that need not be, and category 2 costs included only if the taxpayer's financial statements treat them as inventoriable (the book-conformity rule). The review works each GL account into the correct category and pulls the category 1 and elected category 2 costs into COGS.

Allocation assumptions

Two allocations run. First, the medical vs adult-use split — both plant-touching, so this allocates shared production cost between product lines on a canopy square-footage basis, the more defensible measure for cultivation. Second, the §280E line vs non-§280E line split — shared overhead is allocated between the plant-touching businesses (COGS-only) and the ancillary holding business (deductible), on the separate-trade-or-business principle of CHAMP. Bases are documented, not assumed.

Expense classification review

Each expense account is reviewed and reclassified: production vs period, direct vs indirect, §1.471-11 category, and §280E line vs non-§280E line. A sample is pulled and tested (Exhibit D). Misclassified period costs stay out of COGS — over-inclusion is as much an exam risk as under-inclusion.

Risk areas

• Over-inclusion. Pushing non-production period costs into COGS invites disallowance; the method is defensible only if the line holds both ways.
• Book conformity. Category 2 costs must match financial-statement treatment (§1.471-11(c)(2)(iii)); inconsistency undercuts the position.
• Change in method. Correcting the costing method may require a §446 change with a §481(a) adjustment rather than a simple restatement.
• Reseller reach. Retail COGS cannot be inflated beyond §1.471-3; only cultivation gets full absorption.

Recommended adjustments

Reclassify the identified indirect production costs into cultivation COGS under §1.471-11; apply the square-footage and CHAMP allocations; leave retail COGS on §1.471-3; document each move to the account and authority. Detail and owners are in Recommendations and Exhibit A.

Implementation notes

Implement via a corrected chart of accounts (Exhibit C) and, where the correction is a method change, a Form 3115 with the §481(a) adjustment. Where a position departs from a regulation, disclose on Form 8275-R. Prior-year corrections are filed only within the §6511 window and only where defensible.

Final conclusions

A materially larger, defensible COGS position is available to the cultivation entity under §1.471-11 — not by stretching §263A, but by correctly absorbing indirect production costs the operator already incurs. The retail entity's COGS is correctly limited. The method, once corrected, carries into both the go-forward transition and any prior-year claim.

§280E / COGS issue register

Controlling authority or evidence type is flagged for each item. Conclusions are illustrative and not asserted until run against real books. Exposure bands are order-of-magnitude illustrations, not estimates for any taxpayer.

Adjustments, with owner and deadline

Owners and targets are placeholders; real sequencing follows the sample review.

• Do not rely on §263A to pull additional costs into COGS — it does not apply where §280E denies the deduction.
• Do not inflate retail (reseller) COGS beyond §1.471-3.
• Keep period costs out of COGS — over-inclusion is an exam risk.
