What are my Marijuana Excise Tax Obligations?
Per RCW 69.50.535 and WAC 314-55-089, all licensees are required to remit to the Washington State Liquor Control Board (WSLCB) an excise tax of 25 percent on all taxable sales of marijuana, marijuana concentrates, useable marijuana, and marijuana-infused products. This tax is specific to marijuana sales and does not include transportation costs or retail sales tax amounts.
