A Connecticut proposal that would overhaul how the state taxes marijuana has been scheduled for a public hearing on March 11 in the Joint Committee on Finance, Revenue and Bonding.
House Bill 5109, introduced by State Representative Jason Rojas (D), would eliminate the state’s current potency-based THC tax and replace it with a flat 10.75% excise tax on marijuana sales.
Under current law, Connecticut imposes a tax based partly on the total THC content of marijuana products. That means items with higher potency face higher tax rates, a structure that differs from the percentage-based systems used in several other states.
HB 5109 would remove the THC-based tax entirely and instead apply a single 10.75% excise tax to marijuana purchases. Supporters of the proposal say a flat-rate system could simplify compliance for businesses and provide consumers with more predictable pricing.
The measure reflects a broader discussion among lawmakers about whether potency-based taxes create unintended effects in the marketplace, including price differences driven by tax formulas rather than consumer demand.
A similar proposal has already been introduced in the Senate by State Senator Jason Perillo (R), titled Senate Bill 59. Both bills have been referred to the Joint Committee on Finance, Revenue and Bonding.
