The proposed General Assembly Committee Bill No. 5109 aims to overhaul the current Cannabis Total THC Tax by introducing a new excise tax structure effective October 1, 2026. The bill repeals Section 12-330ll of the 2026 supplement to the general statutes and establishes a flat tax rate of 10.75% on gross receipts from cannabis sales by retailers, hybrid retailers, and micro-cultivators. This change eliminates the previous tax rates that were based on the total THC content of various cannabis products, such as plant material and edibles, which were assessed at specific rates per milligram of THC.

Furthermore, the bill delineates the responsibilities of cannabis retailers and cultivators in collecting the new tax at the point of sale, with exemptions for palliative use and transfers to transporters. It introduces penalties for non-compliance, including a 25% penalty on unpaid taxes and interest accruing at 1% per month. The bill also emphasizes electronic filing and payment methods to enhance the efficiency of tax collection. Additionally, it specifies the allocation of tax revenues to various funds, including the Cannabis Social Equity and Innovation Fund and the Cannabis Prevention and Recovery Services Fund, over the fiscal years from 2022 to 2029. The bill clarifies that the term "person" includes various business entities responsible for tax compliance and states that the commissioner will not issue refunds for taxes paid under this new structure.
