Full-absorption costing for a biological production cycle
A Cultivation Facility license produces inventory on a schedule set by plant biology, not the calendar. Clones root, vegetate, flower, and get harvested on staggered timelines across multiple rooms, which makes standard month-end costing methods a poor fit unless the accounting system is built around production phases and harvest batches from the start.
IRC 471 requires full-absorption costing, meaning direct costs like nutrients and trim labor and indirect costs like grow-light electricity, HVAC, dehumidification, and facility depreciation should all be capitalized into inventory. Cultivators who expense these costs as incurred, rather than capitalizing them into cost of goods sold, forfeit deductions that 280E would otherwise allow — a mistake that shows up as an inflated tax bill, not an audit flag, which is why it so often goes unnoticed.
Plant and harvest tracking through METRC
Every plant in a Colorado cultivation facility carries a METRC tag from clone or seed through harvest, destruction, or transfer, with phase changes and waste logged as they happen. When a harvest batch's recorded weight doesn't reconcile against the plant count and phase history in METRC, it creates a variance that's difficult to explain retroactively — and that MED inspectors, lenders, and potential buyers all know to look for.
We build harvest batch reconciliation into the monthly close: METRC plant and harvest reports get compared against the cost accounting system's batch records so wet weight, dry weight, trim, and waste all tie together before the numbers get finalized.
- Batch-level cost tracking tied to METRC harvest lot numbers
- Documented waste and destruction procedures matching MED requirements
- Cost-per-pound reporting broken out by strain, room, and harvest cycle
The Average Market Rate and excise tax exposure
The 15% marijuana excise tax applies to the first transfer of retail marijuana from a cultivation facility. When that transfer happens at arm's length to an unrelated retailer, the actual sale price sets the tax base. When product transfers between commonly owned cultivation and retail or manufacturing licenses, the Department of Revenue's quarterly published Average Market Rate applies instead.
Vertically integrated operators need a documented, consistent methodology for which rate applies to which transfer, because inconsistent treatment across transfers is one of the more visible red flags in a DOR excise tax examination.
Turning yield data into a real cost-per-pound number
Owners, lenders, and potential investors all want to know the true cost per pound by strain and by room — not a blended facility average that hides which strains are actually profitable and which are being subsidized. That requires tying labor hours, utility usage, nutrient cost, and facility overhead to specific harvest batches, not just totaling expenses for the month.
Once that cost data exists, it feeds directly into pricing decisions, strain selection, and capacity planning — turning the accounting function from a compliance obligation into an operating tool.
