Cannabis Tax Information

Overview of the Statewide Cannabis Tax

The statewide Cannabis Tax is a tax that is imposed on retail sales of cannabis plant materials, cannabis edible products, and cannabis (other than cannabis plant material or cannabis edible products) by a cannabis retailer, hybrid retailer, or micro cultivator and is based upon the amount of tetrahydrocannabinol (THC) per milligram of said products.

It is important to note that retail sales of cannabis for adult use are authorized to begin at 10:00 a.m. on Tuesday, January 10, 2023.

Calculation of the Statewide Cannabis Tax

There are three different tax rates under the statewide Cannabis Tax. The applicable tax rate is determined by the type of product that is being sold. To this end, the statewide Cannabis Tax is imposed on the following products at the following rates:

  • Cannabis plant materials: Six hundred twenty-five-thousandths of one cent ($0.00625) per milligram of total THC, as reflected on the product label;
  • Cannabis edible products: Two and seventy-five-hundredths cents ($0.0275) per milligram of total THC, as reflected on the product label; and
  • Cannabis, other than cannabis plant material or cannabis edible products: Nine-tenths of one cent ($0.009) per milligram of total THC, as reflected on the product label.

The statewide cannabis tax is in addition to the municipal level cannabis tax and the Sales and Use taxes. The example below illustrates the application of all three taxes:

Example: Chocolate Bar (100 mg of total THC/20 servings of 5 mg each)
Sales Price: $30.00

Municipal Level Cannabis Tax

Each sale of cannabis made by a cannabis retailer, hybrid retailer, or micro-cultivator that is subject to the statewide Cannabis Tax is also subject to the municipal level cannabis tax.

Although DRS is not responsible for collecting the municipal level cannabis tax, the Department does play a role in the administration of this tax.

Each such municipality must provide contact information to DRS. Any and all questions related to the municipal level cannabis tax should be directed to the municipality in which the retailer, hybrid retailer, or micro-cultivator is operating.
