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 1st through Sept 30th
- 2nd Quarter October 1st through December 31st
- 3rd Quarter January 1st through March 31st
- 4th Quarter April 1st through June 30th.
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.
