Cannabis Tax Audit Defense

Cannabis tax audit defense isn't a luxury in an industry the IRS scrutinizes more closely than almost any other. Because cannabis businesses operate under IRC 280E, a single audit can put years of deductions, your cash position, and even your peace of mind at risk. It also puts the burden of proof squarely on you. The good news: with the right records and the right partner, an audit becomes something you're prepared for, not something that blindsides you.

Why Cannabis Businesses Get Audited

Cannabis operators face audit exposure that ordinary businesses simply don't. Under 280E, you can't deduct normal operating expenses, so the IRS pays unusually close attention to the one area where deductions are allowed: your Cost of Goods Sold (COGS). Books that mix personal and business spending, inventory that isn't tracked from seed to sale, or COGS allocations you can't substantiate are exactly what trigger adjustments, penalties, and interest. When the notice arrives, you typically have weeks, not months, to produce clean and defensible records.

Note: as of April 2026, state-licensed medical cannabis has moved to Schedule III and is no longer subject to 280E, while adult-use operations remain under Schedule I, so where you fall determines your exposure, and we'll help you pin that down.

How Our Cannabis Tax Audit Defense Works

Our approach combines proactive preparation with hands-on support. We review your chart of accounts, inventory, and COGS methodology against what IRC 280E and 471 actually permit, then strengthen weak documentation before it ever becomes a liability. If you're already under examination, we organize your substantiation, help you respond to IRS information document requests, and work alongside your tax attorney or represent your financials directly so you're never facing an examiner with a shoebox of receipts and a guess.
