Ohio Cannabis Tax Guide: 2026 Edition

Federal Rescheduling Developments & Section 280E in 2026

Section 280E addresses a trade or business consisting of trafficking in a Schedule I or II controlled substance. A proposed rule, hearing or announcement is not enough to establish a taxpayer's treatment. Confirm the effective federal classification, the covered activity, relevant dates and IRS guidance before taking a position; this guide does not certify the final disposition of federal proceedings as of October 16, 2026. Where 280E applies, ordinary deductions can be disallowed while properly determined cost of goods sold reduces gross receipts in calculating gross income. Preserve inventory support and model the cash effect separately from book profit.

Defending Deductions Against 280E With Cost Allocation

Because Section 280E reaches deductions but not cost of goods sold, the entire defense rests on which costs are properly inventoriable and whether the allocation supporting that classification existed contemporaneously. Producers apply full absorption costing under Treasury Regulation Section 1.471-11, which capitalizes direct materials, direct production labor, and a defined set of indirect production costs. Resellers such as dispensaries are limited to invoice cost and certain acquisition costs. A vertically integrated Ohio group must run both models and prove the line between them.

• Capture facility, department, and cost-center codes at the point of entry rather than reconstructing allocations at year end.
• Use measurable drivers: square footage from a current facility plan for occupancy, sub-metered kilowatt hours for production utilities, timecard hours for labor and supervision.
• Keep selling, marketing, delivery, general administrative, and interest costs firmly outside inventory; attempting to shelter them is the fastest route to an adjustment with penalties.
• Retain a written costing policy, approved before the year begins, and apply it without mid-year changes made to chase a result.

280E COGS Isolation & an Ohio Cannabis Chart of Accounts

COGS isolation means separating inventory cost from operating expense and supporting each movement with source records, not creating a deduction by renaming an account. Use distinct accounts for purchased inventory, production work in process, finished goods, eligible direct production labor, allocable production overhead, retail wages, administrative wages and selling costs. Maintain location, department and legal-entity dimensions so a production facility's costs do not disappear into a dispensary's expense pool. Producers and resellers need different inventory analyses under the applicable Section 471 rules.

• Separate adult-use and medical revenue; keep sales tax and adult-use excise collected in distinct liability accounts rather than revenue or COGS.
• Reconcile beginning inventory plus supported additions less ending inventory to COGS, explaining transfers, shrink and adjustments separately.
• Tie purchase invoices, freight support, production timecards and batch records to the inventory rollforward and written costing policy.
• Keep CAT, municipal tax provisions, payroll withholding payables and operating expenses outside inventory unless a specific applicable rule supports different treatment.
• Review retail vs. production labor by actual duties; account labels alone do not establish federal tax eligibility.

Medical and Adult-Use Cost-Allocation Models

Ohio dual-use facilities need separate medical and adult-use sales records under the current Chapter 3796 framework. Adult-use excise tax is addressed in Section 3796.40, effective March 20, 2026. The two channels have different customer documentation and excise treatment, but channel labels alone do not determine federal 280E treatment or create a sales-tax exemption. Preserve revenue and tax-category detail while applying inventory methods based on actual business activity.

Ohio's 10% Adult-Use Excise Tax

Ohio Revised Code Section 3796.40 imposes a 10% excise tax on adult-use marijuana retail sales, in addition to applicable sales and use tax. Qualifying medical-program sales are outside this adult-use excise; that distinction is not a general medical sales-tax exemption. Reconcile adult-use taxable sales, excise collected and remittances by reporting period. Keep the liability separate from sales revenue and operating cash planning. The Ohio Department of Taxation administers adult-use marijuana tax reporting; verify current return instructions and due dates before filing.

• Separate ledger accounts for excise tax collected, excise tax remitted, and any timing difference between the two.
• Point-of-sale tax configuration reviewed after every product catalog change, price change, or software update.
• Monthly reconciliation of taxable gross receipts per the point-of-sale system to revenue per the financial statements, with documented reconciling items.
• Retained filing confirmations and payment records tied to the corresponding period close package.

State and Local Sales Tax Variation

Ohio's state sales tax rate is 5.75%, and counties and transit authorities add permissive rates on top of it, producing a combined rate that varies by delivery location rather than by the seller's headquarters. For a single-store dispensary the combined rate is a constant that still must be verified when county rates change. For a multi-location operator or any licensee making deliveries, the rate is a function of the destination, and the system must be configured to source each transaction correctly. Errors here compound quietly: an under-collected rate becomes an assessment against the operator, not the customer.

Commercial Activity Tax (CAT) & Municipal Net Profit Taxes

Ohio's Commercial Activity Tax (CAT) is based on Ohio taxable gross receipts, not net profit, so a loss does not necessarily eliminate liability. For 2025 and later, Ohio Department of Taxation guidance provides a $6 million annual exclusion and a 0.26% rate on taxable receipts above that exclusion. Review receipts sourcing, statutory exclusions and combined or consolidated group treatment before assuming each entity gets a separate exclusion. Municipal net profit taxes are a separate calculation: review Chapter 718 adjustments, entity treatment, nexus, apportionment and the relevant city's administration. Do not assume the federal 280E disallowance flows through unchanged into every municipal return. Maintain a book-to-federal-to-municipal reconciliation with support for each adjustment.

Filing Calendar, Estimates, and Cash Planning

Build the tax calendar from current account-specific requirements: sales and adult-use excise returns, CAT registration and quarterly filings where required, federal and municipal estimates, annual returns and payroll deposits. Do not rely on outdated CAT annual-filer thresholds. Where Section 280E applies, federal estimates require a tax-adjusted projection rather than book profit alone. Reserve cash for those obligations and segregate collected sales and excise tax from operating cash; reconcile each return to the ledger and retain filing and payment confirmations.

• Maintain a written tax calendar with owners, due dates, and confirmation of filing retained in the period close file.
• Compute federal estimates from a 280E-adjusted forecast updated at least quarterly.
• Segregate collected transaction taxes from operating cash.
• Reconcile every filed return to the general ledger before it is submitted, not after.

Examination Exposure and Recordkeeping

Cannabis returns draw scrutiny at both the federal and state level, and the questions are predictable: how was cost of goods sold computed, what allocation drivers were used, when were they documented, do inventory quantities agree to the state monitoring system, and do reported gross receipts agree to the point-of-sale records and the excise filings. Every one of those questions is answerable in advance. Reconcile monitoring-system quantities to inventory at the package level each period, tie point-of-sale gross receipts to excise and sales tax filings and to financial statement revenue, retain manifests and destruction records, and keep the costing policy and allocation support in the same file as the return. Records maintained contemporaneously are evidence. Records assembled after a notice are argument.
