Maine Cannabis Tax Rate in 2026: 14% Sales Tax & 280E
What the 14% retail rate covers, how excise tax 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.
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.
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.
- 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
What tax rate applies to adult-use cannabis in Maine in 2026?
For retail sales on or after January 1, 2026, Maine applies a 14% sales-tax rate to adult-use cannabis and adult-use cannabis products. This is the applicable state sales-tax rate for those items, not a separate cannabis tax added on top of the general sales-tax rate.
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 distinguishes them from prepared food that does not contain cannabis.
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.
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.
