Complete 2025 Guide to 280E & COGS
The cannabis industry has evolved from a black market operation to a legitimate multi-billion dollar sector, yet it faces unique accounting challenges that no other industry encounters. With medical marijuana now legal in 38 states and recreational use permitted in 24, cannabis businesses must navigate a complex web of federal tax restrictions, state regulations, and traditional accounting principles. This comprehensive guide addresses the critical accounting requirements for medical marijuana businesses in 2025, with particular focus on Section 280E compliance and Cost of Goods Sold (COGS) optimization.

Understanding Section 280E: The Cannabis Tax Burden
Section 280E of the Internal Revenue Code represents the single most significant financial challenge facing cannabis businesses today. Enacted in 1982 following a court case involving a cocaine trafficker who successfully claimed business deductions, this provision prohibits businesses trafficking in controlled substances from deducting ordinary business expenses from their federal taxes.
Since marijuana remains a Schedule I controlled substance under federal law, all state-legal cannabis businesses fall under 280E restrictions. This means while a traditional business might pay an effective tax rate of 15-30%, cannabis businesses often face effective tax rates of 70% or higher. The impact is devastating: a cannabis retailer generating $2 million in revenue with $1.5 million in total expenses might owe $400,000 in federal taxes, compared to just $100,000 for a non-cannabis business with identical financials.
The only exception within 280E allows for the deduction of Cost of Goods Sold (COGS). This narrow allowance has transformed COGS optimization from a routine accounting practice into a survival strategy for cannabis businesses. Every dollar properly allocated to COGS directly reduces taxable income, making the difference between profitability and bankruptcy for many operators.
Maximizing COGS: Your Primary Tax Strategy
Cost of Goods Sold becomes the lifeline for cannabis businesses operating under 280E restrictions. The IRS allows COGS deductions because they're considered adjustments to gross receipts rather than business expense deductions. Understanding what qualifies as COGS versus ordinary business expenses requires careful analysis and documentation.
For cannabis cultivators and manufacturers, COGS includes direct materials like seeds, growing medium, nutrients, and packaging materials. Direct labor costs for cultivation, harvesting, trimming, and processing qualify as COGS. Indirect production costs such as facility rent for grow spaces, utilities for cultivation areas, quality testing required for production, and depreciation on cultivation equipment also fall under COGS.
Retailers face more restrictions but can still include inventory purchase costs, transportation and handling fees directly related to acquiring inventory, and certain labor costs associated with inventory management. The key distinction lies in activities that directly relate to acquiring or producing inventory versus those that support sales or general business operations.
Cannabis businesses must implement sophisticated inventory tracking systems that capture all allowable COGS elements. This includes tracking labor hours by function, allocating overhead costs between production and non-production activities, and maintaining detailed documentation for every expense claimed as COGS. The difference between aggressive and conservative COGS allocation can mean hundreds of thousands in tax savings annually.
Essential Accounting Practices for Compliance
Successful navigation of cannabis accounting requires implementing robust systems and practices that go beyond traditional bookkeeping. The stakes are higher when every transaction faces potential federal scrutiny and state regulatory review.
Segregation of activities becomes paramount. Cannabis businesses should separate production activities from retail operations whenever possible, ideally through distinct legal entities. This separation allows for cleaner COGS allocation and may provide opportunities for the production entity to operate with lower 280E impact. Track employee time meticulously, distinguishing between COGS-eligible activities like cultivation and processing from non-deductible activities like marketing and sales.
Documentation standards must exceed typical business requirements. Every expense requires clear documentation showing its business purpose and relationship to COGS if applicable. Maintain contemporaneous records rather than attempting to reconstruct allocations during tax preparation. Create standard operating procedures for expense classification and ensure all accounting staff understand 280E implications.
Cash management presents unique challenges since many financial institutions remain hesitant to serve cannabis businesses. Those that do obtain banking services must maintain meticulous records of all cash transactions. Implement dual control procedures for cash handling, conduct daily cash reconciliations, and use video surveillance to document cash management processes. Consider hiring armored car services for large cash deposits to maintain clear audit trails.
State vs. Federal Requirements: Navigating Dual Systems
Cannabis businesses operate in a unique regulatory environment where state legality conflicts with federal prohibition. This creates dual compliance obligations that significantly complicate accounting practices.
Most states with legal cannabis programs don't apply 280E restrictions to state taxes, allowing standard business deductions. This means maintaining two sets of books: one for federal reporting under 280E restrictions and another for state reporting with full deductions. This dual system requires sophisticated accounting software capable of managing multiple tax treatments for the same transactions.
State regulations often impose additional requirements including seed-to-sale tracking systems that monitor every plant and product throughout the supply chain. These systems generate massive amounts of data that must integrate with financial reporting. States may require specific reporting formats, submission schedules, and audit procedures that differ from federal requirements.
Sales tax compliance adds another layer of complexity. Cannabis businesses typically face higher tax rates than other retailers, with some jurisdictions imposing taxes exceeding 30% on retail sales. These taxes may apply at multiple levels - state, county, and city - each with different rates, exemptions, and filing requirements. Medical marijuana often faces different tax treatment than recreational products, requiring systems to distinguish between customer types and product categories.
Technology Solutions and Best Practices
Modern cannabis accounting demands specialized technology solutions designed to handle industry-specific requirements. Generic accounting software lacks the functionality to manage 280E calculations, dual reporting requirements, and integration with state tracking systems.
Cannabis-specific ERP systems have emerged to address these needs. These platforms integrate point-of-sale systems with inventory management, compliance reporting, and financial accounting. They automate COGS calculations based on predefined rules, generate compliant reports for various jurisdictions, and maintain audit trails that satisfy both state and federal requirements.
Implementing these systems requires careful planning and configuration. Map your chart of accounts to clearly separate COGS-eligible expenses from operating expenses. Configure automated workflows that route expenses to appropriate categories based on vendor, description, or other criteria. Establish approval hierarchies that ensure proper review before finalizing COGS allocations.
Regular reconciliation becomes critical when managing complex systems. Reconcile inventory counts between physical counts, seed-to-sale tracking, and financial records at least monthly. Review COGS allocations quarterly to ensure consistency and compliance. Conduct mock audits annually to identify weaknesses before regulators or tax authorities discover them.
Accounts Receivable Challenges
The cannabis industry's cash-heavy nature doesn't eliminate accounts receivable challenges. Business-to-business transactions between cultivators, manufacturers, and retailers often involve payment terms, creating collection challenges unique to the industry.
Without access to traditional banking services, many businesses struggle to process payments efficiently. Electronic payments may be unavailable, forcing reliance on cash or cash equivalents. This creates security risks and complicates reconciliation processes. Businesses extending credit must implement robust collection procedures since legal remedies for non-payment may be limited.
Collection strategies must account for the inability to use traditional tools like credit cards or ACH transfers. Some businesses have found success with cryptocurrency payments or third-party payment facilitators designed for cannabis transactions. Others maintain strict cash-on-delivery policies to eliminate collection risk entirely.
Bad debt reserves require special consideration under 280E. While bad debt expenses aren't deductible as operating expenses, they may reduce gross receipts if properly documented. This makes timely write-offs and accurate aging reports essential for tax optimization.
Professional Support and Expertise
The complexity of cannabis accounting makes professional expertise invaluable. General practitioners often lack the specialized knowledge required to optimize 280E positions or navigate state-specific requirements. Cannabis-focused accounting firms have emerged to fill this gap, offering expertise in COGS optimization, multi-state compliance, and audit defense.
When selecting professional support, evaluate their specific cannabis experience, understanding of both federal and state requirements, and track record with businesses similar to yours. Ask about their approach to COGS allocation, experience with IRS audits, and relationships with state regulators.
Consider engaging multiple specialists for different needs. A cannabis-focused CPA for tax planning and compliance, a CFO consultant for financial strategy and systems implementation, and specialized collection agencies familiar with industry challenges can form a comprehensive support team.
Preparing for the Future
The cannabis accounting landscape continues evolving rapidly. Federal legalization proposals could eliminate 280E restrictions overnight, fundamentally changing financial strategies. States continue refining their regulatory frameworks, potentially adding new requirements or modifying existing ones. Banking reform might improve access to financial services, reducing cash management burdens.
Businesses must build flexibility into their accounting systems to adapt to these changes. Maintain detailed records that would support full deductions if 280E disappears. Implement systems scalable enough to handle multi-state expansion. Develop relationships with financial institutions positioned to serve cannabis businesses when regulations permit.
