Built because
no one else
did it right.

The industry deserved
a real firm.

420Ledger started from a conversation that kept repeating itself. Every dispensary owner we talked to described the same situation: their accountant used standard QuickBooks, didn't understand 280E, and told them to "hope for the best" at tax time. The result was tens of thousands of dollars in preventable overpayment, year after year.

Cannabis is not a general business category with a few unusual line items. It operates under IRC §280E, a federal statute that disallows the deductions every other business takes for granted — salaries, rent, utilities, marketing. The only path to a defensible tax position is a correctly structured chart of accounts, precise COGS allocation, and documentation that survives IRS scrutiny. None of that comes from retrofitting a generic accounting workflow.

So we built the infrastructure from scratch. A purpose-built accounting platform with 280E compliance, multi-state cannabis excise tax logic, MSO consolidations, and payroll integration all native to the system. Then we built a firm around it. No legacy processes carried over from a general accounting practice. No software retrofitted with a cannabis add-on. Every workflow, every category, every report format was designed specifically for plant-touching businesses.

We are headquartered in New Jersey — one of the most complex cannabis regulatory environments in the country — with deep expertise in NJ Cannabis Regulatory Commission compliance, quarterly SEEF filings, and the NJ CBT treatment of 280E disallowance. We serve clients in 27 states, including multi-state operators whose books span multiple regulatory regimes simultaneously.

420Ledger is not a CPA firm. We are a PTIN-registered, EFIN-authorized tax preparation and bookkeeping firm that works exclusively in cannabis. That focus is deliberate. The cannabis accounting space has no room for part-time attention — the rules are too consequential, and they change too fast.
