About the Academy

A curriculum built by a practitioner — not a publisher.

The Cannabis Accounting Academy is the education brand of GAC Advisory LLC, a virtual advisory practice led by a licensed CPA. It exists for one reason: cannabis accounting is the hardest niche in tax, and there has never been a serious, federal-first path into it.

The Story

Why this exists.

Cannabis accounting is a field where documentation is the defense — and where there is no established playbook to inherit.

Most accountants meet their first cannabis client unprepared, not through any fault of their own, but because the rules are genuinely different. Under §280E, ordinary deductions vanish. The line between cost of goods sold and operating expense — computed under §471 — becomes the single most important number on the return, and it is audited more aggressively than in any other industry.

Get it wrong, and a client overpays federal tax by six figures, or files a return that cannot survive an examination. Get it right, and you become the practitioner an operator cannot afford to lose.

This Academy is the path I wish had existed — a structured, federal-first curriculum that takes a bookkeeper, EA, or accountant from orientation to a defensible, certifiable practice, and on to CFO- and transaction-level advisory.

The background behind it

Generalized — credibility, not endorsement
01

Auditor at a Big Four firm

Learned defensible documentation under the highest standards.

02

Corporate accounting, technology sector

Managed high-growth complexity in a fast-moving environment.

03

The world's largest asset manager

Handled regulatory and financial reporting at institutional scale.

04

A private-markets affiliate

Built accounting processes, systems, and memos from the ground up.

The Approach

Institutional rigor, applied to the hardest niche in tax.

Cannabis work demands the discipline of audit, the depth of corporate accounting, and the ability to build systems where none exist. That combination is exactly what this curriculum distills — not abstract theory, but the methodology, the charts of accounts, the workpapers, and the mock engagements a practitioner actually uses on a live client.

Every module ships with worked examples, a test bank, and the templates the work requires — so you finish ready to take a client, not merely informed.

What Guides It

Three principles behind every module.

Defensible by default

If a position can't survive an examination, it doesn't belong in the curriculum. Documentation is treated as the deliverable, not an afterthought.

Federal-first, honestly scoped

The core is 100% federal and applies in all 50 states. State specifics are separate add-ons — so the foundation never goes stale.

Built on real systems

Templates, workpapers, and full mock engagements — the same artifacts used in practice — so learning transfers directly to client work.

Start Where You Are

Become the practitioner operators build around.

Whether you're weighing your first cannabis client or building toward Cannabis CFO, there's a clear next step — and it begins with the federal foundation.
