Cannabis Tax Due Dates

On April 5, 2022 the Board of Supervisors approved a resolution extending the Cannabis Business Tax Payment Deadlines for Cannabis Cultivation from January 31, 2022 and April 30, 2022 to May 31, 2022. Cultivators will have until May 31, 2022 to pay the 1st installment/2nd quarter AND the 2nd installment/3rd quarter without penalties or interest. 

This extension does not effect the Cannabis Business Tax Payment due date for Cannabis Supply Chain Operations (Retail/Dispensary and Manufacturing) which is April 30, 2022. Supply Chain Operators will have until April 30, 2022 to pay the 2nd quarter. The 3rd quarter tax deadline is April 30, 2022. 

Please note: These extensions do not effect the tax liability that is due in any way. The 4th quarter due date remains July 31, 2022.

Cannabis Tax Ordinance Amendments

On April 19, 2022 the Board of Supervisors adopted an ordinance amending the County's Cannabis Business Tax Ordinance (codified in Sonoma County Code Chapter 35). The Ordinance accomplishes the following:
  • Reduce the cultivation tax rates by 45% effective July 1, 2021 with a sunset on the reduction on June 20, 2023. 
  • Amend lanugage for consistency and clarification, including clarifying language regarding operator audits and providing financial records, including gross receipts data, to County consultants.

Continuing Multi-tenant Cannabis Land Uses

Multi-tenant Ordinance (No. 6356) Section III(a) states “The expiration date for each zoning permit is hereby extended for 5 years from the date the permit was issued, except that a zoning permit will expire if the use ceases for a continuous period of one year.”   Under this provision, if a multi-tenant cannabis operator wishes to forgo a growing season without expiring their permit, the operator must demonstrate the use has not ceased by maintaining their local cannabis cultivation permit and state cultivation license, maintaining title or lease of the land, paying inspection fees, allowing inspections, complying with BMPs, requesting canopy verifications as needed, and filing tax statements.

Cannabis Equity Program

The Governor's Office of Business and Economic Development (GO-Biz), in partnership with the Department of Cannabis Control, provides Cannabis Equity Grants Program for Local Jurisdictions. This program seeks to advance economic justice for populations and communities disproportionately affected by cannabis prohibition by providing funding to local jurisdictions that are committed to promoting equity in the legal cannabis marketplace and eliminating barriers to entering the regulated cannabis industry.
