Testing Laboratories
Accounting for California Cannabis Testing Laboratories
Testing laboratories sell analytical services rather than cannabis products, which changes the tax analysis substantially. The accounting challenges are capital intensity, instrument utilization and sample throughput economics rather than inventory costing.

Financial challenges specific to this license type
Capital equipment intensity
Analytical instruments carry high acquisition and maintenance costs, making depreciation strategy and financing structure central to the financial model.
Cost per sample
Profitability depends on throughput per instrument and per analyst. Cost per sample by test panel is the operating metric that matters.
Revenue recognition
Service revenue is recognized as testing is performed, with attention to prepaid packages, rush fees and retest obligations.
Tax treatment
A laboratory's relationship to 280E depends on the specific facts of its licensing and handling, and the position should be documented rather than assumed favorable.
