Cannabis businesses operating within incorporated cities should consult with city authorities

SAN LUIS OBISPO COUNTY — During its Tuesday, June 20, meeting, the San Luis Obispo County Board of Supervisors voted to reduce the Cannabis Business Tax (CBT) rate to 6 percent, a reduction that will apply to transactions that occur on or after July 1.

Back in 2018, San Luis Obispo County voters approved the CBT, a measure applicable to cannabis businesses operating within the county’s unincorporated areas. This voter-approved measure stipulates an automatic 2 percent increase in the cannabis tax rate each July 1, up to a maximum of 10 percent, unless the Board of Supervisors votes to hold or reduce the tax rate.

Starting from July 1, all cannabis business transactions taking place in the county’s unincorporated areas will be taxed at the revised rate of 6 percent. CBT reporting and remittance for the July period will be due on or before August 31. It is important to note that CBT returns for the June 2023 period (due on or before July 31) will still be assessed at the current 8 percent CBT rate.

Please note: Cannabis businesses operating within the seven incorporated cities in the County should consult with their respective city authorities regarding tax obligations.
