Adult-use retail sales carry three charges. First, a 10.75 percent state cannabis excise tax under M.G.L. Chapter 64N. Then the 6.25 percent state sales tax, applied to the transfer price plus excise. Finally, a local option tax of up to 3 percent where the host community has adopted it. Combined, that reaches roughly 20 percent in most major cities. Medical sales are exempt from all three. Separately, a host community may charge a Community Impact Fee, which is assessed on gross sales rather than profit and negotiated locally.

A Community Impact Fee is charged by a host community in relation to the actual costs that a marijuana establishment imposes on it. It sits outside the excise and sales tax stack and is assessed on gross sales rather than on profit. Because it is negotiated locally, two operators in neighbouring towns can carry very different fixed costs on identical revenue. It belongs in your pricing model and expansion analysis, so treat it as a cost of doing business in that municipality rather than as a tax line.

IRC 280E disallows ordinary business expense deductions on federal returns for businesses trafficking in controlled substances. Cost of goods sold remains deductible, so the planning lives in how much of your spend can be properly classified as COGS. Following the April 2026 rescheduling of state-licensed medical cannabis to Schedule III, operators holding both medical and adult-use licences now run two federal tax regimes at once. Adult-use activity stays under 280E, which makes the split between the two an accounting question rather than an operational one.

An Act Modernizing the Commonwealth's Cannabis Laws took effect in April 2026. The Act reduced the Cannabis Control Commission from five commissioners to three, all appointed by the Governor. Retail licence caps rose from three to six, though non-equity operators face a lower limit during the first two years. Medical marijuana licensees no longer face the vertical integration requirement. Adult-use delivery expanded statewide, reporting requirements tightened for businesses carrying debt, and the Commission must now study the excise tax rates and hemp-derived cannabinoid products.

Possibly, but model the tax effect first. Medical Marijuana Treatment Centers previously had to grow and process what they sold. With that requirement removed, an operator can separate cultivation, manufacturing, and retail into distinct entities. That changes cost of goods sold allocation, creates transfer pricing between related parties, and shifts how much spend stays deductible under IRC 280E. A structure that looks cleaner operationally can produce a worse tax outcome, so the analysis should come before the filing.

The Commission's social consumption regulations took effect in January 2026, creating supplemental, hospitality, and event organizer licence categories. On-site consumption mixes cannabis revenue with hospitality revenue, and the two carry very different treatment under IRC 280E. Food, beverage, and service revenue that does not involve trafficking in a controlled substance is not subject to the same disallowance. Separating those revenue streams cleanly from the first day of operation is far easier than reconstructing the split later.

For a licensed operator, yes. Massachusetts cannabis accounting turns on details a generalist misses. A generalist CPA typically does not build cost of goods sold allocation around IRC 280E, will not know how the Community Impact Fee behaves, and has no experience reconciling METRC inventory against a general ledger. The consequence is usually one of two outcomes: overpaying federal tax through missed COGS opportunities, or taking aggressive positions that do not survive examination. Neither is visible until it costs money.

Yes. Multi-state operators are a core part of the practice, and the complexity usually sits in the differences between states rather than within any one of them. Massachusetts, Maine, Connecticut, and New York each treat cannabis tax differently, and state conformity to IRC 280E varies. We handle the consolidated picture alongside each state filing.

We start with an onboarding review. That surfaces any 280E, COGS, or compliance issues needing attention from prior years. Next we build a transition plan, request records from your existing accountant, and set a date for the handover. Most transitions happen between filing periods, though we regularly pick up mid-year where a return is outstanding or a deadline is at risk.
