California Cannabis Business Taxes: A 2026 Guide
When California rolled out its first cannabis taxes alongside adult-use sales in January 2018, the structure was complicated and heavy: a 15% excise tax plus a separate cultivation tax charged per dry-weight ounce. The framework has been overhauled significantly since then. Here is how California cannabis taxes actually work in 2026 — and why the changes matter for your margins.
How the Tax Structure Changed
| Tax | 2018 | 2026 |
|---|---|---|
| Cultivation tax | $9.25/oz flower, $2.75/oz leaves | Repealed (AB 195, 2022) |
| Excise tax | 15% on retail | 15% through 2028 (AB 564 rolled back the 19% hike) |
| State sales tax | 7.25% base | 7.25% base plus local rates |
| Collected by | Distributor remits to CDTFA | Retailer collects and remits to CDTFA |
Permits Still Come First
Before making any sales, a cannabis business must obtain a seller's permit from the California Department of Tax and Fee Administration (CDTFA). That permit is a prerequisite for state licensing through the Department of Cannabis Control. The registration step has not gone away — it remains the foundation that ties your sales activity to the state's tax system.
The Excise Tax in 2026
The headline change customers feel is the excise tax. It briefly rose to 19% on July 1, 2025, but AB 564 — signed in September 2025 — reversed that increase and set the rate back to 15% of gross retail receipts through 2028, a move aimed at helping legal operators compete with the illicit market. Retailers now collect the excise tax directly at the point of sale and remit it to the CDTFA, rather than routing it through distributors as the original 2018 system required.
The Cultivation Tax Is Gone
One of the most significant reforms was the repeal of the cultivation tax. Under the original framework, growers paid a per-ounce levy — $9.25 for flower and $2.75 for leaves — regardless of whether the product sold or at what price. AB 195 eliminated that tax in 2022, removing a major fixed cost that had squeezed cultivators in a market with falling wholesale prices. Today there is no separate cultivation tax to calculate or remit.
Filing in Practice
All cannabis businesses that make sales must file sales and excise tax returns electronically and pay the CDTFA directly. You are required to file and report your sales numbers even in periods where none of your sales are taxable. Because penalties for late or inaccurate filing are steep, a POS that captures tax data cleanly at every transaction is essential — keeping your California cannabis business audit-ready and your returns accurate without manual reconciliation.
An Honest Take
California's tax history is a case study in learning the hard way. The 2018 structure taxed cultivators on weight they had not yet sold, stacked levies on top of one another, and handed the illicit market a built-in price advantage. Repealing the cultivation tax and freezing the excise rate at 15% were overdue corrections, not gifts. For operators, the lesson is to build tax handling into daily operations rather than treating it as a quarterly scramble — the rules will keep shifting, and the businesses that track every dollar in real time are the ones that survive the next change.
