Cannabis Taxation

After the passage of Measure A, the Sonoma County Cannabis Business Tax on March 7, 2017, businesses engaged in the cultivation or manufacturing of cannabis/cannabis products within the unincorporated areas of Sonoma County are required to pay taxes. These tax rates are based on several factors including license type and business segment. 

Information and forms for quarterly and semi-annually tax returns can be found on our Cannabis Tax Forms page.
