Recreational marijuana in Massachusetts is taxed at a combined rate of up to 20%, made up of three separate charges collected at the register: the 6.25% state sales tax, a 10.75% state excise tax, and a local option tax of up to 3%. Patients with a valid medical marijuana card pay none of these. Cannabis businesses, meanwhile, face a federal tax rule that denies them most ordinary business deductions, which pushes effective federal rates far above what other retailers pay.
What You Pay at the Register
Three taxes stack on every recreational cannabis purchase. The dispensary collects all three on a single receipt and forwards the money to the state and the host municipality.
The first is the regular Massachusetts sales tax of 6.25%, applied the same way it is to most retail goods.1Mass.gov. Sales and Use Tax for Businesses It covers flower, edibles, concentrates, and every other adult-use product.
The second is a 10.75% excise tax on the total sales price. This one applies only to recreational marijuana and sits on top of the sales tax, bringing the state-level rate to 17%.2General Court of Massachusetts. Massachusetts General Laws Part I, Title IX, Chapter 64N, Section 2
The third is a local option tax. Cities and towns that host cannabis retailers can add up to 3% on top of the state rates.3General Court of Massachusetts. Massachusetts General Laws Chapter 64N, Section 3 – Local Tax Option A municipality that imposes the full 3% pushes the total to 20% of the purchase price, and most host communities do levy the maximum. That revenue goes directly to the municipality.
Beyond what shows up on a receipt, retailers also pay their host city or town a Community Impact Fee of up to 3% of gross annual sales, capped at eight years and tied to actual costs the business imposes on the municipality.4Cannabis Control Commission Massachusetts. Guidance on Community Impact Fees You will not see this one itemized, but it influences shelf prices.
Medical Patients Pay Nothing
If you hold a valid Massachusetts medical marijuana card, your purchases are exempt from all three taxes: the 6.25% sales tax, the 10.75% excise tax, and any local option tax.5Mass.gov. Marijuana Retail Taxes FAQs In a town that levies the full local rate, that is a 20% price difference against the same product sold on the adult-use side.
The state treats medical cannabis the way it treats prescription medication. The Department of Revenue has confirmed in a formal directive that the sales tax exemption for prescription medicine applies to marijuana sold to a qualifying patient, or that patient’s personal caregiver, with a physician’s written certification.6Massachusetts Department of Revenue. Directive 15-1 – Sales Tax Exemption for Medical Marijuana Dispensaries check the patient’s active card and government-issued ID before applying the exemption.
The state exemption does not carry over to your federal return. The IRS says that amounts paid for controlled substances not legal under federal law cannot be included as deductible medical expenses, even where state law allows the use.7Internal Revenue Service. Publication 502 – Medical and Dental Expenses So patients save at the register but cannot write those costs off at tax time.
Where the Money Goes
Massachusetts collected roughly $289 million in state cannabis tax revenue in fiscal year 2025, drawn from about $1.65 billion in adult-use sales.8Cannabis Control Commission Massachusetts. Massachusetts Adult-Use Cannabis Sales Generated $1.65 Billion in 2025
Revenue from the 10.75% excise flows into the Marijuana Regulation Fund. From there, 15% is allocated to the Cannabis Social Equity Trust Fund, which supports grants and no-interest or forgivable loans for businesses in the state’s equity programs. The other 85% is appropriated through the annual state budget and can fund the Cannabis Control Commission, substance addiction services, agricultural resources, municipal police training, and public safety programs.9Cannabis Control Commission Massachusetts. Cannabis Revenue Flow in Massachusetts Host municipalities with at least one social equity retailer also receive quarterly payments equal to 1% of total sales from those retailers.
Sales tax collections go into the state’s general fund like any other retail sales tax, and local option revenue stays with the city or town that imposed it.
The Federal Problem for Cannabis Businesses
If you operate a dispensary, cultivation site, or manufacturer, state taxes are the smaller part of the picture. Federal tax law treats you very differently from any other legal retailer.
Section 280E of the Internal Revenue Code bars any deduction or credit for expenses tied to a business that traffics in Schedule I or Schedule II controlled substances.10Office of the Law Revision Counsel. 26 U.S. Code 280E – Expenditures in Connection With the Illegal Sale of Drugs Marijuana remains Schedule I under federal law, so every state-licensed cannabis business is caught. Rent, payroll, marketing, insurance, and most other ordinary operating costs cannot be deducted. Effective federal tax rates on cannabis companies routinely land between 50% and 70% of gross profit.
The one allowance is cost of goods sold. Cannabis businesses can subtract the direct cost of acquiring or producing their inventory when calculating gross income. For retailers, that typically means the invoice price paid to a cultivator or manufacturer plus transportation. For cultivators and manufacturers, it extends to direct materials, direct labor, and certain indirect production costs like utilities, rent on growing facilities, and equipment maintenance.11Internal Revenue Service. Cannabis Reporting – Recreational, Medical, Illegal Marketing, advertising, selling expenses, and general administrative overhead remain fully non-deductible.
Rescheduling Could Change This
The Department of Justice proposed in May 2024 to reschedule marijuana from Schedule I to Schedule III, which would end the Section 280E problem entirely. The rulemaking is still pending. Until it is finalized, Section 280E still applies, and 2025 returns should be filed accordingly.
Cash Reporting Rules
Most banks still avoid cannabis clients, so the industry runs largely on cash. That triggers federal reporting rules other retailers rarely deal with.
Any business that receives more than $10,000 in cash from a single transaction, or from related transactions, must file IRS Form 8300 within 15 days.12Internal Revenue Service. Instructions for Form 8300 – Report of Cash Payments Over $10,000 Received in a Trade or Business For a busy dispensary, that can mean frequent filings. The same $10,000 threshold applies under FinCEN rules, and cannabis businesses do not get the exemptions available to other cash-heavy industries.13Financial Crimes Enforcement Network. BSA Expectations Regarding Marijuana-Related Businesses
Paying federal taxes in cash adds its own friction. A cannabis business making a cash payment to the IRS must schedule an in-person appointment at a Taxpayer Assistance Center 30 to 60 days in advance, bring the exact amount, and have it counted on site in exchange for a receipt. Payments over $10,000 prompt a confirmation call from the IRS before the appointment, and not every Taxpayer Assistance Center accepts cash.14Internal Revenue Service. What to Expect When You Pay Cash at an IRS Office
Filing the State Return
Before opening, a dispensary must register with the Massachusetts Department of Revenue through MassTaxConnect, which happens after the Cannabis Control Commission issues a Notice to Commence Operations. Licensed delivery operators register as vendors and collect the same taxes.5Mass.gov. Marijuana Retail Taxes FAQs
Marijuana retailers file monthly, regardless of sales volume. Returns are due on or before the 30th day of the month following the collection period and must be filed electronically.15Mass.gov. 830 CMR 64N.1.1 – Marijuana Retail Taxes A single form covers the sales, excise, and local option tax. Medical sales are not reported on the marijuana tax return.
Retailers must keep records that separate recreational from exempt medical sales, including the exact amount collected for each tax component, and preserve them at least three years after the return’s due date or filing date, whichever is later.16Massachusetts Department of Revenue. 830 CMR 62C.25.1 – Record Retention Failing to collect or remit can bring penalties and interest.
