Quick history of medical marijuana legalization in Oklahoma
Oklahoma voters approved medical marijuana in 2018 through State Question 788.
Since then, the program has grown into one of the largest medical cannabis markets in the country.
Recreational cannabis is still not legal in Oklahoma, so all retail activity is limited to licensed patients and caregivers.
Today, thousands of dispensaries and hundreds of thousands of cardholders make up this regulated market, supported by compliance systems and oversight through the Oklahoma Medical Marijuana Authority (OMMA).

Overview of excise tax, state sales tax, and local add-ons
Every cannabis purchase in Oklahoma comes with unique taxes that are different from standard retail goods.
A 7% state cannabis excise tax applies to all medical marijuana sales at the point of purchase.
On top of that, Oklahoma’s 4.5% state sales tax is added, along with additional city and county local sales taxes, which vary by location.
This combination of taxes contributes millions of dollars each year to state revenue and makes tax compliance an important part of the industry.

Market landscape: dispensaries, patients, and compliance with Metrc
Oklahoma’s cannabis industry is unique for its accessibility.
The state has issued thousands of dispensary licenses and continues to register a large patient base.
To ensure transparency, the state requires cannabis businesses to track inventory through Metrc, a seed-to-sale system that documents every plant and product from cultivation to sale.
This compliance system helps prevent diversion and ensures products move only through the legal marketplace.
For patients, that means purchases at licensed dispensaries such as High Society’s Oklahoma City and Norman shops are fully traceable and compliant with state law.
Federal Tax Treatment of Cannabis
IRS Section 280E and what it means for cannabis businesses
At the federal level, cannabis remains a Schedule I controlled substance.
This means businesses that handle cannabis fall under Internal Revenue Code Section 280E, which limits tax deductions.
Cannabis businesses cannot deduct most ordinary expenses like rent, payroll, or advertising, even if they are fully legal at the state level.
The result is that cannabis companies often face a heavier tax burden than other industries.
Why medical cannabis isn’t deductible on federal returns
For individual taxpayers, the rules are also strict.
Even though many states, including Oklahoma, allow medical marijuana, the IRS does not recognize cannabis as a deductible medical expense.
Patients cannot list medical cannabis purchases as itemized medical deductions on their federal tax returns.
This difference between state legality and federal prohibition is one of the biggest challenges for both patients and businesses.
What’s allowed: Cost of Goods Sold (COGS)
Despite the restrictions of Section 280E, cannabis businesses are allowed to deduct the Cost of Goods Sold (COGS).
This includes the direct costs of producing or acquiring inventory, such as cultivation supplies or wholesale purchasing.
While this deduction does not cover most operational expenses, it is the primary way cannabis businesses reduce their taxable income on federal returns.
For dispensaries across Oklahoma, including High Society’s locations, careful recordkeeping of COGS is essential for compliance.
State Tax Rules on Cannabis Expenses
States allowing deductions for cannabis businesses
Some states have taken steps to ease the tax burden on cannabis businesses.
Colorado, California, Michigan, Montana, Oregon, and several others allow cannabis companies to deduct business expenses on state tax returns, even though those deductions are denied federally.
This helps level the playing field for local operators in those states.
Where Oklahoma currently stands on deductions
As of 2025, Oklahoma does not allow any special state tax deductions for cannabis businesses.
Like all other businesses, dispensaries must pay state income tax, but they cannot offset expenses that are disallowed under federal law.
That means planning around tax liability is especially important for dispensary owners here in Oklahoma.
Why Oklahoma patients can’t deduct medical cannabis as expenses
Medical cannabis purchases in Oklahoma are also not deductible for patients at the state level.
Neither federal nor state tax law recognizes these expenses as deductible medical costs.
This means patients are responsible for the full purchase price plus excise and sales taxes.

Cannabis Taxation in Oklahoma Explained
7% excise tax and how it’s applied
Oklahoma places a 7% excise tax specifically on medical marijuana retail sales.
This tax is calculated on the sales price of cannabis products before additional state and local sales taxes are added.
The excise tax is collected by dispensaries at the time of purchase and remitted to the state.
4.5% state sales/use tax and local variability
In addition to the excise tax, Oklahoma charges a 4.5% state sales and use tax on cannabis purchases.
Local governments—such as Oklahoma City or Norman—may also apply additional municipal or county sales taxes.
These local rates vary, which means the total tax rate at checkout can differ depending on where the dispensary is located.
You can compare products and prices at our High Society dispensaries to find what fits your budget.
Income tax brackets in Oklahoma for 2025
For 2025, Oklahoma applies state income tax rates ranging from 0.25% to 4.75%, depending on taxable income levels.
Cannabis businesses, like all other businesses in Oklahoma, are subject to these rates on their reported net income.
Because federal deductions are restricted by Section 280E, dispensary owners must be mindful that their taxable income for state purposes may not reflect the full range of expenses incurred.
For shoppers, this means the cannabis taxes you pay at the register support not only the state’s medical program but also broader public revenues.
Recordkeeping and Compliance for Cannabis Businesses
OMMA rules and Metrc seed-to-sale requirements
Oklahoma cannabis businesses operate under the strict oversight of the Oklahoma Medical Marijuana Authority (OMMA).
Every licensed dispensary, grower, and processor must use Metrc, the state’s seed-to-sale tracking system.
Metrc documents the full life cycle of cannabis, from cultivation through to the final retail sale, ensuring every product sold in Oklahoma is accounted for.
This system prevents diversion, enforces transparency, and provides the state with a verifiable audit trail.
At High Society’s locations, compliance with OMMA and Metrc is a standard part of daily operations.
Importance of keeping receipts, invoices, and patient records
Recordkeeping goes beyond Metrc.
Dispensaries are required to maintain clear records of every transaction, including receipts, invoices, and patient verification documents.
For patients, this ensures their purchases are logged under a valid medical marijuana card.
For businesses, keeping these documents organized helps verify compliance with tax filings and inventory control.
Strong recordkeeping also helps when customers need proof of purchase or when state regulators conduct reviews.
Audit readiness and avoiding penalties
With cannabis being one of the most heavily regulated industries, audits are a reality.
Businesses that maintain complete sales records, tax filings, and compliance logs are best positioned to pass inspections without issue.
Failing to document transactions properly or misreporting taxes can result in penalties, fines, or even license suspension.
By maintaining audit-ready files, dispensaries protect their business and ensure they can continue serving local patients without disruption.
Practical Tax Planning for Oklahoma Dispensaries
Maximizing COGS to reduce liability
Because federal law limits most business deductions under Section 280E, dispensaries rely on Cost of Goods Sold (COGS) to reduce taxable income.
This includes the direct costs of acquiring or producing inventory, such as wholesale purchases, cultivation supplies, and product testing.
A well-organized COGS strategy ensures dispensaries aren’t paying more tax than necessary.
Careful accounting helps Oklahoma businesses stay competitive in a heavily taxed market.
Filing strategies for dispensary owners
Oklahoma dispensaries file both federal and state income taxes like any other business.
However, they must carefully adjust their filings to account for the restrictions of 280E.
Many owners work with accountants who specialize in cannabis taxation to ensure they’re properly balancing excise, sales, and income tax responsibilities.
Filing accurately and on time also helps dispensaries avoid costly penalties.
Staying updated on legislative changes
Cannabis tax laws evolve quickly, both at the state and federal levels.
Oklahoma legislators may consider reforms in the coming years, and federal changes could shift how deductions work under 280E.
For business owners, staying informed through trusted sources and industry associations is critical.
It ensures compliance today and positions them to adapt quickly if new tax breaks or reporting rules are introduced.
How State Tax Changes Could Impact Patients and Businesses
Potential for reform in Oklahoma
While Oklahoma currently does not offer special deductions for cannabis expenses, that could change in the future.
Other states have updated their tax codes to better support cannabis businesses, and Oklahoma may follow suit as the market matures.
Reform could also impact how patient costs are taxed at the state level.
Lessons from other cannabis-legal states
States like Colorado, California, and Michigan have implemented policies that allow cannabis businesses to deduct expenses on state returns.
These policies provide insight into how Oklahoma might structure future reforms.
Learning from these examples helps dispensary owners and policymakers anticipate what works — and what challenges to avoid.
Advocacy and staying informed
Patients and businesses play an important role in shaping cannabis policy.
By staying active in community discussions and tracking updates from OMMA and the Oklahoma legislature, stakeholders can advocate for fairer tax structures.
Being engaged ensures that when reforms are proposed, the voices of patients and local dispensaries are heard.
