How Medical Cannabis Is Taxed in Hartford
Qualifying registered medical patients are exempt from the 10.75% state cannabis excise and the 6.35% state sales tax. In practice that trims roughly $17.10 off every $100.00 spent versus an adult-use purchase in Hartford, though the 3% Hartford cannabis business tax may still apply depending on the local ordinance.
Why Is Cannabis Taxed This Much in Hartford?
Cannabis in Hartford carries layers of tax that ordinary retail goods never see. Connecticut adds its 10.75% cannabis excise on top of ordinary sales tax, and Hartford then collects an additional 3% cannabis business tax on licensed retailers — a cost dispensaries pass through to the customer. That stacking is why the register total at a Hartford dispensary can run noticeably higher than the same product in a lower-tax Connecticut city or across the state line.
Connecticut is replacing its THC-potency tax (0.625¢/mg on flower, 0.9¢/mg on edibles, 2.75¢/mg on other products — roughly 10–15% of retail) with a flat 10.75% excise on gross receipts effective October 1, 2026, under a 2026 law. Combined with 6.35% state sales + 3% municipal tax, the effective rate runs ~20–26% under either structure. Medical cannabis is exempt.
