Cannabis Taxation & 280E

Overview

Here's the problem: cannabis is still illegal at the federal level, which means standard tax deductions don't apply to cannabis businesses. IRC Section 280E (26 U.S.C. 280E) blocks you from writing off rents, marketing, salaries, and most other things normal businesses take for granted. This drives effective tax rates way higher than you'd expect.

This isn't optional knowledge. If you don't plan for 280E from day one, it will catch you off guard when you're filing. The good news: it can be managed, and Maine's state-level deductions help.

Section 280E Definition Explained

Section 280E was originally enacted to prevent drug traffickers from deducting business expenses. Because cannabis remains illegal at the federal level, cannabis businesses-even those fully compliant with state law-are subject to this provision.

What 280E Actually Means for Your Business:

• No normal deductions - rent, utilities, marketing, most salaries. Gone.
• Only COGS is deductible - what you paid for the product you sold. That's it.
• Effective tax rate is higher - don't believe the "70-90%" headlines. With good COGS management, you're usually looking at 40-60% effective rates in practice.
• Applies to everyone - cultivation, manufacturing, retail, medical caregivers. If you touch cannabis, 280E applies.

Hidden Challenge: The All-or-Nothing Trap

Watch out for this one: 280E applies to your entire business if any part of it touches cannabis. If you own a coffee shop and a dispensary under the same LLC, the IRS can argue 280E applies to the coffee shop too. Keep separate businesses under separate legal entities.

Cost of Goods Sold (COGS): Your Only Real Deduction

When 280E kills your deductions, COGS is what you have left. In a dispensary, this is basically what you paid for your inventory - the flower, concentrates, edibles on your shelves. If you bought it for $1,500/lb and sold it for $3,000/lb, your taxable income is $1,500/lb. That's your COGS lifeline.

Vertical Integration Changes the Math

If you own cultivation too, you can often push more costs into COGS - labor, power, nutrients - because those are "production" expenses. A dispensary with its own grow can legally lower its taxable income more than a store that just buys from a cultivator. This is why most serious Maine operators eventually move toward vertical integration. See our Cultivation Guide for details on Tier licensing.

Maine State Taxes: The Good News

Here's the split to understand: Maine is not the IRS. On your Maine state return, you can deduct normal business expenses. This makes a real difference - your state tax burden is closer to a normal business.

What Maine Collects (per M.R.S. Title 28-B):

• Sales Tax: 14% on adult-use cannabis sales (effective January 1, 2026) Source: Maine OCP Compliance Guidelines, 2026
• Excise Tax: Per-pound fee - $335 per pound of flower, different rates for other product types Source: M.R.S. Title 28-B, 2025
• Income Tax: Maine corporate rates apply, and you can take normal deductions here

Local X-Factor: Maine's State Tax Deduction Advantage

What sets Maine apart from most other states: Unlike the federal government, Maine allows cannabis businesses to take normal business deductions on your Maine state tax return. This includes rent, payroll, marketing, and operating expenses - the same deductions any Maine business takes.

The practical impact: If your dispensary has $500K in revenue and $300K in expenses (rent, staff, marketing), you pay Maine state tax only on the $200K profit - not the full $500K. In most other cannabis states, you'd pay tax on $500K at the federal level, then get crushed by 280E eliminating your $300K deductions.

Under M.R.S. Title 28-B 301, Maine has explicitly separated its cannabis income tax framework from federal 280E treatment, giving Maine operators a meaningful edge in net profitability compared to operators in states without similar provisions.

The Financial Impact — Real Numbers

Let's look at what 280E actually costs a Maine dispensary. Here's a realistic scenario for a $500K revenue operation:

The Maine advantage: on your state return, you deduct the $150K in operating expenses. On your federal return, you cannot. This means your total tax burden is significantly lower than a cannabis operator in a state that doesn't decouple from 280E.

280E and Maine Municipal Taxes

Some Maine municipalities impose local taxes based on net income. The question operators ask: does 280E apply at the local level? The answer depends on how the municipality calculates its tax base. Most Maine towns that impose local business taxes follow the state's income tax framework — which means they allow the same deductions Maine allows. This is another layer of Maine's tax advantage.

However, if your municipality calculates its tax based on federal taxable income (before state adjustments), 280E could apply at the local level too. Check with your town's tax assessor or a Maine cannabis CPA to understand your specific situation.

Book-to-Tax Differences for Maine Cannabis

The difference between your book income (what your accounting software shows) and your tax income (what you report to the IRS) creates deferred tax items. This is a technical area, but understanding it matters for financial planning:

Your CPA should prepare a book-to-tax reconciliation annually. This is not optional — it's how you defend your 280E positions if the IRS audits you.

How to Position for an IRS Audit

IRS audits of cannabis businesses are thorough and increasingly common. The IRS has a dedicated cannabis audit program. Here's what you need to be ready for:

• Metrc-to-financial reconciliation: The IRS will pull your Metrc data and compare it to your POS and accounting records. Any discrepancy is a red flag.
• COGS documentation: Every dollar you claim as COGS must be documented. Invoices, receipts, inventory logs, cultivation records. If you can't prove it, it's not deductible.
• Entity separation proof: If you have a management company separate from your licensed entity, the IRS will scrutinize the relationship. Inter-company agreements, arm's-length pricing, and separate bank accounts are essential.
• Safe harbor positions: Some 280E positions have IRS safe harbors. Your CPA should know which ones apply and whether you qualify.

Hiring a Cannabis-Savvy CPA in Maine

This is not the place to save money. A general CPA who doesn't understand 280E, Metrc, or Maine's cannabis tax framework will cost you far more in missed deductions and compliance errors than a cannabis-specialized CPA charges in fees.

What to look for in a Maine cannabis CPA:

• Experience with 280E: They should be able to explain COGS maximization strategies without hesitation
• Maine-specific knowledge: Understanding of Maine's state-level decoupling, local tax treatment, and OCP reporting requirements
• Metrc familiarity: They should know how to reconcile Metrc data with financial records
• Entity structuring expertise: Ability to advise on management company vs. licensed entity separation
• Audit defense experience: They should have handled IRS cannabis audits before

How to Actually Reduce Your 280E Burden

Here's what's working for Maine operators who stay profitable:

1. Track Every Gram - Your POS needs to match Metrc exactly. Use systems designed for cannabis, not generic retail software.
2. Separate Entities - Keep your "Management Company" (where you pay yourself, do marketing, etc.) separate from your Licensed Entity. This isolates non-cannabis expenses from 280E exposure.
3. Maximize COGS - Work with a cannabis CPA to attribute every legitimate cost to production. This isn't cheating - it's making sure you're not overpaying.
