the 280E Playbook: Cannabis Taxes, Rescheduling, and Schedule III Transition — What Every Operator Should Bring to Their CPA

The federal government just changed the most punishing tax in American business. Here is what it means for you, and what it does not.For decades, Section 280E has done something no other tax does. It taxes cannabis businesses on money they never get to keep. It denies the ordinary deductions every other company takes for granted, including rent, payroll, marketing, and security, and it leaves operators paying tax on close to the top line instead of the bottom line. In 2026, that finally started to change, and the change is still in motion.The 280E Playbook is the operator's field guide to the transition. Written by a J.D., it explains in what the April 2026 rescheduling did, who it helped, who it left behind, and what to do next. This is the book you read first, and then bring to the professional who files your return.Inside, you will get a clear, current answer to: - What the April 2026 Schedule III order actually changed, and what it left untouched- Why medical and recreational operators are now on opposite sides of a federal tax line- Whether your business qualifies for relief, with a simple way to find your category- The retroactive refund question everyone is asking, and why waiting is not a strategy- Which deductions survive, how cost of goods sold works, and where the real traps are- How the June 2026 hearing, the court challenges, and the politics could still move the line- A concrete action plan to take to your CPA, before the clock runs outWhy this book, and why nowMost cannabis tax books were written years ago, before any of this happened. This one is built for the moment. It is a living transition guide, current as of June 2026, that tells you what is settled, what is still in play, and how to make decisions when the law itself is moving.It is honest about what nobody knows yet. It does not oversell the relief, it does not promise refunds, and it does not pretend the story is finished. What it does is hand you the map, the legal and strategic picture every operator needs before making a single move.A note on what this is: This book is legal and strategic education. It is not legal advice and it is not tax advice. Every number belongs to your CPA. Think of it as the briefing you bring to the table.If you run a dispensary, cultivation, processing, or ancillary cannabis business, or you advise one, and you want to understand the biggest shift in cannabis taxation in a generation, start here.
