The CDTFA (California Department of Tax and Fee Administration) is charged with determining the California excise markup amount every six months.
Earlier this year it was raised from 60% to 80%. The CDTFA has now released its determination for what the markup will be for June-December 2020 and it will remain 80%.
Distributors of cannabis products are responsible to calculate and collect the excise tax from retailers. You can find out more about cannabis tax rates and calculations at CDTFA.ca.gov
