Cannabis growers in parts of Sonoma County will see tax rate rise while others to pay less

The Sonoma County Board of Supervisors is poised to give final approval Tuesday to new business tax rates for cannabis cultivators in unincorporated areas of the county that would nearly double the top rate for indoor growers.

The new rates, which received tentative approval last week, would maintain the current tax structure on cultivators, which calculates the amount owed based on the square footage of canopy permitted to be grown.
