Maine Weed & Cannabis Tax in 2026: 14% Rate & 280E
What the 14% adult-use rate covers, the 5.5% medical rate, how excise differs, and where §280E fits
The short answer
Retail sales: one 14% adult-use rate
Maine Revenue Services Instructional Bulletin 61, last revised December 22, 2025, says retail sales of adult-use cannabis and adult-use cannabis products are taxed at 14% beginning January 1, 2026. The rate applies to flower, concentrates, edibles, tinctures, topicals, plants, seedlings, and seeds sold as adult-use cannabis or adult-use cannabis products.
“Maine weed tax” and “Maine marijuana tax” are informal names for this same rate: the statute taxes adult-use cannabis regardless of the label. The 14% replaces the general 5.5% sales-tax rate on those items rather than adding to it.
Edibles do not receive a second prepared-food tax. MRS states that an edible cannabis product is taxed at the adult-use cannabis rate. Prepared food without cannabis and unrelated merchandise are classified separately under the sales-tax rules.
Medical marijuana sales: the general 5.5% rate
The 14% adult-use rate does not reach every cannabis sale. 36 M.R.S. §1811(1)(D)(5) applies the elevated rate to cannabis and cannabis products “if sold by a person to an individual who is not a qualifying patient.” Medical marijuana sold to registered qualifying patients — through registered dispensaries or caregivers under Title 22 — therefore falls under the general 5.5% sales-tax rate rather than the 14% adult-use rate.
This distinction is why outdated summaries that stack “10% + 5.5%” or apply a single rate to all cannabis are wrong: the rate depends on whether the sale is adult-use or to a qualifying patient.
Cultivation excise tax is separate
The excise tax in 36 M.R.S. §4923 is imposed on specified sales or transfers by adult-use cultivation facility licensees. It is not another percentage charged to the retail customer.
| Item | Rate |
|---|---|
| Flower | $223 per pound or fraction |
| Trim | $63 per pound or fraction |
| Immature plant or seedling | $1 each |
| Mature plant | $23 each |
| Seed | $0.20 each |
Section 4923 also addresses multiple-license transfers and an exemption for sales or transfers to another licensed cultivation facility. Operators should apply the current statutory text to the actual transaction rather than assume every wholesale movement is taxed the same way.
Federal §280E and Maine’s state subtraction
The IRS cannabis FAQ, reviewed April 26, 2026, says IRC §280E disallows deductions or credits for a business that sells or otherwise traffics marijuana. The IRS also says properly calculated cost of goods sold may reduce gross receipts under IRC §471. That is not the same as treating ordinary operating expenses as deductible.
Maine has its own income-tax adjustments. 36 M.R.S. §5122(2)(PP) and §5200-A(2)(BB) provide subtractions for otherwise allowable business expenses disallowed under federal §280E for defined Maine cannabis businesses. These provisions do not rewrite the federal return, and the applicable Maine section depends on the taxpayer’s filing posture.
Practical compliance boundary
- Use 14% as the adult-use cannabis sales-tax rate; do not add 5.5% or a prepared-food rate to the same cannabis item.
- Apply the general 5.5% rate to medical marijuana sold to registered qualifying patients.
- Classify non-cannabis merchandise separately under MRS guidance.
- For cultivation transfers, check the current §4923 transaction rule and exemptions.
- Keep federal §280E treatment distinct from any Maine subtraction and have a qualified tax professional apply the correct return instructions.
Frequently asked questions
How much is the weed tax in Maine?
14%. For retail sales on or after January 1, 2026, 36 M.R.S. §1811 makes 14% the applicable state sales-tax rate for adult-use cannabis and adult-use cannabis products. Maine statute taxes “adult use cannabis”; “weed” and “marijuana” are informal terms for the same products, so the same 14% rate applies.
Is Maine’s weed tax charged on top of regular sales tax?
No. 36 M.R.S. §1811 sets 14% as the applicable state sales-tax rate for adult-use cannabis and adult-use cannabis products — it replaces, rather than stacks on, the general 5.5% rate for the same item. General merchandise sold by a dispensary, such as paraphernalia and apparel, remains subject to the general sales-tax rate under Maine Revenue Services guidance.
What tax do medical marijuana patients pay in Maine?
Medical sales are not subject to the 14% adult-use rate. Under 36 M.R.S. §1811(1)(D)(5), the elevated rate applies to cannabis and cannabis products sold to an individual who is not a qualifying patient; sales of medical marijuana to registered qualifying patients fall under the general 5.5% sales-tax rate. Confirm your transaction treatment with a Maine tax professional.
Did Maine’s marijuana tax go up in 2026?
Yes. The adult-use cannabis sales-tax rate rose from 10% to 14% for sales occurring on or after January 1, 2026, per 36 M.R.S. §1811 as amended by PL 2025, c. 87 and PL 2025, c. 388, Pt. F. The same budget also revised cultivation-level excise-tax rates under 36 M.R.S. §4923.
Are Maine cannabis edibles taxed at 14% or at the prepared-food rate?
Adult-use cannabis edibles are adult-use cannabis products and are taxed at the 14% adult-use cannabis sales-tax rate. Maine Revenue Services Instructional Bulletin 61 distinguishes them from prepared food that does not contain cannabis, which is classified separately.
What are Maine’s 2026 adult-use cannabis excise-tax rates?
Beginning January 1, 2026, Title 36 §4923 sets rates of $223 per pound of flower, $63 per pound of trim, $1 per immature plant or seedling, $23 per mature plant, and 20 cents per seed. The excise tax is a cultivation-level tax, distinct from the 14% retail sales tax.
Do consumers pay the Maine cannabis excise tax at the register?
No. The excise tax in 36 M.R.S. §4923 is imposed on specified sales or transfers by adult-use cultivation facility licensees, not on retail customers. A consumer buying adult-use cannabis pays the 14% sales-tax rate; the excise tax is settled at the cultivation level.
Does IRC §280E still matter to a Maine cannabis business?
Yes. Current IRS guidance says §280E disallows deductions or credits for a business that sells or traffics marijuana, while properly calculated cost of goods sold may reduce gross receipts. Maine statutes provide a state income subtraction for otherwise allowable expenses disallowed federally under §280E, but eligibility and calculation depend on the taxpayer and return.
