Yes, cannabis dispensaries pay federal taxes, and they pay more of them than almost any other kind of retailer. Under Section 280E of the Internal Revenue Code, a state-licensed dispensary cannot deduct most of the ordinary expenses that reduce a normal business’s taxable income, so it owes federal income tax on a far larger share of revenue than a comparable company in another industry. Effective federal tax rates in the industry routinely exceed 70%.
Why the Federal Bill Is So High
Over 40 states have legalized cannabis in some form, but the federal government still classifies marijuana as a Schedule I controlled substance under the Controlled Substances Act.1Drug Enforcement Administration. Drug Scheduling That classification triggers Section 280E, which says no deduction or credit is allowed for amounts paid in carrying on a business that consists of trafficking in Schedule I or Schedule II controlled substances.2Office of the Law Revision Counsel. 26 USC 280E Expenditures in Connection With the Illegal Sale of Drugs
The IRS applies 280E to every state-legal cannabis operation, from a large multi-state cultivator down to a single-location shop. A state license doesn’t change the federal calculation.
What Dispensaries Can Still Subtract
Section 280E blocks deductions, but it doesn’t change how gross income is calculated. Cost of Goods Sold is not technically a deduction. It’s the calculation that determines gross income in the first place, and courts have consistently upheld that reading. COGS is the single most important lever a dispensary has to reduce its federal tax bill.2Office of the Law Revision Counsel. 26 USC 280E Expenditures in Connection With the Illegal Sale of Drugs
For a dispensary that buys finished products from a cultivator or processor, COGS includes the invoice price of that inventory plus freight and transportation to get it to the store. For a vertically integrated operator that grows its own cannabis, COGS can capture more: seeds and clones, soil and growing media, water, electricity used for cultivation, and the wages of employees who physically grow and harvest the plants. Processing labor, packaging tied directly to production, and inspection costs can also qualify if the business keeps detailed inventory records under Section 471.
The line between COGS and operating expense is where most disputes land. Rent for a cultivation room is arguably part of production costs. Rent for the retail sales floor is an operating expense 280E blocks. Getting the allocation right takes meticulous record-keeping and a tax professional who works in cannabis.
What Dispensaries Cannot Deduct
Everything outside COGS is off limits. For a normal retailer, rent, marketing, insurance, payroll, and professional fees all reduce taxable income. For a dispensary, none of those touch the federal tax bill:
- Rent and utilities allocated to the retail sales floor, administrative offices, or non-production space.
- Marketing, advertising, signage, social media, and branding.
- Wages of budtenders, managers, security, and administrative staff not directly involved in producing or acquiring inventory.
- Legal, accounting, and consulting fees.
- General overhead: banking fees, software subscriptions, office supplies, insurance, point-of-sale systems.
Consider a dispensary with $2 million in revenue, $800,000 in COGS, and $900,000 in operating expenses. It owes federal tax on $1.2 million (revenue minus COGS only), not on the $300,000 in actual profit a normal business would report. At the 21% corporate rate, that’s $252,000 in federal tax on $300,000 of real profit. The business keeps $48,000 before state taxes even enter the picture.
That math is why a dispensary spending heavily on security, compliance staff, or retail buildouts sees none of that investment reduce its federal tax obligation. Operators have called 280E a bigger threat to viability than banking restrictions or local zoning.
Legal Ways to Reduce the 280E Burden
Maximizing Cost of Goods Sold
The most common strategy is capturing every cost that legitimately qualifies as COGS. Smaller cannabis businesses with annual gross receipts below $25 million can elect inventory accounting methods that allow a broader range of costs to be capitalized into inventory rather than treated as operating expenses. That can include purchasing costs, storage and handling, and some reselling costs like inspection and packaging labor. The IRS acknowledged this approach in a 2021 Chief Counsel Memorandum, though the specifics depend on the accounting method the business elects. Adopting the right inventory method with a cannabis-specialized accountant is often the highest-return move a dispensary can make.
Separating Cannabis From Non-Cannabis Activities
If a business runs a legitimate non-cannabis line alongside its dispensary, expenses tied to that separate activity can still be deducted. The Tax Court blessed this in a case involving a San Francisco caregiving organization that provided health services to patients alongside its medical cannabis dispensary; the caregiving was found to be a separate trade or business, and properly allocated expenses were deductible despite 280E.
The catch is that the IRS has successfully challenged this strategy far more often than taxpayers have won. To survive scrutiny, the non-cannabis activity needs its own distinct revenue stream, its own customers or service model, and meticulous records documenting the allocation of shared expenses. Bolting a small café or wellness lounge onto a dispensary and calling it a separate business will not work if the operation is clearly just a sideline to cannabis sales.
Payroll and Cash Reporting Still Apply
280E doesn’t exempt cannabis businesses from employment taxes. Dispensaries still withhold federal income tax from wages, pay the employer share of Social Security (6.2%) and Medicare (1.45%), contribute to Federal Unemployment Tax, deposit on the schedule the IRS assigns, and file Form 941 quarterly and Form 940 annually. Wages for retail and administrative staff are not deductible against income tax, but the business owes the employment taxes on them anyway.
Most national banks and credit unions won’t serve cannabis businesses, so many dispensaries operate largely in cash. Any business that receives more than $10,000 in cash from a single transaction, or from related transactions within a 24-hour period, must file IRS Form 8300 within 15 days.3Internal Revenue Service. Instructions for Form 8300 For a busy dispensary, that form gets filed often, and penalties for missing it are steep, with willful failures reaching criminal territory. Paying the federal tax bill itself can mean transporting large amounts of cash to designated IRS offices equipped to accept it.4Taxpayer Advocate Service.

Audit Risk and Penalties
Cannabis businesses face significantly higher audit rates than other industries. Some estimates put the frequency at roughly five times the rate for similarly sized businesses in other sectors. When the IRS audits a dispensary, it focuses on COGS calculations, the allocation of expenses between production and non-production activities, and cash transaction reporting.
If an audit shows a dispensary claimed deductions 280E prohibits, the IRS assesses the additional tax plus an accuracy-related penalty of 20% of the underpayment.5Internal Revenue Service. Accuracy-Related Penalty Interest accrues on both from the original due date until the balance is paid. Some operators have tried deducting expenses and daring the IRS to audit, but the penalties and interest tend to exceed what the business saved.
What Rescheduling Would Change
In May 2024, the Department of Justice published a proposed rule to move marijuana from Schedule I to Schedule III.6The White House. Increasing Medical Marijuana and Cannabidiol Research Section 280E only applies to Schedule I and Schedule II substances, so a Schedule III classification would let cannabis businesses deduct ordinary operating expenses, claim applicable credits, and dramatically reduce their federal tax liability.2Office of the Law Revision Counsel. 26 USC 280E Expenditures in Connection With the Illegal Sale of Drugs
As of early 2026, the rescheduling process has stalled. An administrative law hearing scheduled for January 2025 was postponed because of an interlocutory appeal within the proceeding, and that appeal remains pending with no briefing schedule set. Until the DEA publishes a final rule and the effective date arrives, marijuana remains Schedule I and 280E applies in full. The IRS has been explicit that businesses should not file returns or refund claims based on the assumption that rescheduling has already taken effect.
Whether dispensaries could file amended returns for prior years if rescheduling goes through is an open question. No formal IRS guidance addresses retroactive relief, and the answer will likely depend on the language of the final rule. Operators should keep thorough records of disallowed expenses in case a window for amended returns eventually opens.
State Taxes Sit on Top
Federal tax is only part of the picture. Dispensaries also owe state income taxes, state and local sales taxes, and in many states special cannabis excise taxes. Some states have decoupled from Section 280E and allow ordinary deductions for state tax purposes; others follow the federal treatment and disallow the same expenses. The variation can be worth tens of thousands of dollars a year, so anyone operating across multiple states needs state-specific advice alongside their federal planning.
