What a Cannabis Return Requires
Preparation begins with the books. If inventory is not reconciled, if COGS is a plug, or if the general ledger does not separate inventoriable from non-inventoriable cost, the return cannot be prepared defensibly no matter how skilled the preparer.
We start with a pre-return diagnostic: inventory rollforward tied to track-and-trace, gross receipts tied to POS and to excise filings, payroll tied to filed returns, and a review of every account that feeds the 280E computation. Only then does the return itself get built.
- Federal returns for C corporations, S corporations and partnerships
- California franchise and income tax returns with state adjustment schedules
- Multi-entity consolidations and intercompany eliminations
- Owner-level planning coordinated with the entity return
Book-to-Tax Differences in Cannabis
Cannabis returns carry a set of differences that most preparers rarely encounter together: 280E disallowance at the federal level, California's non-conformity to 280E, inventory capitalization differences between book and tax methods, and depreciation differences where California does not follow federal bonus rules.
Each difference is scheduled and carried forward so the deferred picture stays coherent from year to year, and so a change of preparer never resets the analysis to zero.
Estimated Payments and Cash Tax Management
Because the federal tax base is gross profit, cannabis operators owe tax in years they lose money on a book basis. Prior-year safe harbors are unreliable in a business growing or contracting quickly, and a missed estimate compounds fast with penalties and interest.
We forecast the cash tax obligation quarterly against actual gross margin, coordinate it with excise and local tax due dates, and set aside the funding requirement in advance. In a cash-intensive industry with constrained credit, tax funding is a treasury problem as much as a tax problem.
Filing Positions and Disclosure
Some positions in cannabis tax are settled, some are contested, and a few are genuinely aggressive. We tell you which is which, quantify the exposure, and document the support before filing. Where a position warrants disclosure, we disclose it deliberately rather than by accident.
That transparency is the point. An operator should know exactly which portion of a refund or a low effective rate is durable and which portion is a position that may be adjusted on examination.
Prior-Year Cleanup and Amended Returns
Many California operators arrive with several years of returns prepared without a cannabis-specific methodology — full expense deductions taken federally, COGS understated, inventory never reconciled. Sometimes the right answer is an amended return; sometimes it is a method change; sometimes it is to leave the closed year alone and fix the process going forward.
We evaluate the exposure, the statute of limitations position, and the practical risk of drawing attention, and give a clear recommendation instead of a reflex.
The Federal and California Returns Diverge on Purpose
A licensed California operator files a federal return in which most operating expenses are disallowed and a California return in which they are not. California decoupled from 280E for licensed commercial cannabis activity, so ordinary and necessary business expenses are generally deductible for state purposes. The result is two returns with materially different taxable income and a permanent difference schedule that has to be maintained deliberately.
The preparation workflow reflects that. We compute inventoriable cost and federal taxable income from the cost accounting records, then compute the California result from the book expense base, then reconcile the difference in a schedule that carries forward. Operators who prepare the federal return and back into the state return produce inconsistencies that compound across years.
Entity type layers on top. Pass-through owners receive K-1s carrying income far above distributable cash because of the disallowance, so owner-level estimated payments and distribution policy have to be planned together with the entity return, not after it.
- Federal return driven by inventory accounting and permitted COGS
- California return computed on the book expense base with conformity differences scheduled
- Owner-level K-1 impact and distribution planning for pass-throughs
- Estimated payments modeled on current-year margin, not prior-year safe harbor
Filing Season Runs All Year
By the time the year closes, the return is largely determined. What we control during the year is the quality of the inventory records, the classification discipline in the chart of accounts, the substantiation file, and the estimated payment schedule. A quarterly review that recomputes the projected effective rate on actual results costs a fraction of what a March surprise costs.
We also coordinate the state and local filings that sit alongside the income tax returns: CDTFA sales and use tax, excise obligations where they apply, local cannabis business tax in cities like Los Angeles, Oakland and San Jose, payroll filings and information returns. Missed local filings generate penalties that are small individually and meaningful in aggregate, and they surface during license renewal.
