Portland, Maine Cannabis Tax Rate
14% totalAdministering agencies: Maine Revenue Services · Updated for 2026

Every major Maine city tracked here carries the same combined rate, because Maine does not let cities add their own cannabis tax on top of the state rate. On a typical $100.00 dispensary purchase that works out to roughly $14.00 in tax, or about $114.00 out the door.
Portland is Maine’s largest city; Maine levies a 14% adult-use cannabis sales tax statewide (raised from 10% in January 2026) with no local-option cannabis tax.

Maine taxes adult-use cannabis with a cannabis-specific sales tax at the register — raised from 10% to 14% effective January 1, 2026 by the state budget. A weight-based excise at the cultivation level (reduced and extended to pre-rolls by 2026 legislation) is paid upstream and embedded in shelf prices. Maine has no local option cannabis tax.
