Testing Laboratories
Accounting for Illinois Cannabis Testing Laboratories
A testing laboratory approved by IDOA is selling analytical results, not cannabis, and that distinction changes the tax analysis substantially. The real accounting challenges here are capital intensity, instrument utilization and sample throughput economics — inventory costing barely enters the picture.

Financial challenges specific to this license type
Expensive equipment
Lab instruments carry steep purchase and upkeep costs, which puts depreciation strategy and financing structure at the center of the financial model.
Cost per sample run
Profitability comes down to samples processed per instrument and per analyst. Cost per sample by test panel is the number that actually matters operationally.
Recognizing service revenue
Revenue is recognized as the testing gets performed, with careful handling of prepaid test packages, rush-fee pricing and retest obligations.
Where 280E lands
A lab's relationship to 280E turns on the specific facts of its license and how it handles samples — document the conclusion rather than assuming it's favorable by default.
