After the passage of Measure A, the Sonoma County Cannabis Business Tax on March 7, 2017, businesses engaged in the commercial cannabis industry within the unincorporated areas of Sonoma County are required to pay taxes effective July 1, 2017. Commercial cannabis taxes are calculated and paid each year based on quarterly periods:
- 1st Quarter: July 1 through September 30
- 2nd Quarter: October 1 through December 31
- 3rd Quarter: January 1 through March 31
- 4th Quarter: April 1 through June 30
Our goal is to make this transition as smooth as possible. To that end, this site will provide information relating to how the tax will be applied and how parties interested in operating a cannabis business can pay their taxes. Information covered will include: tax rates, tax forms and due dates, FAQs, and the ability to schedule an appointment with the Tax Collector’s office to pay taxes.
