Talk to a Cultivation CPAWhy Cultivators Need Different Accounting
Cannabis cultivation accounting is bookkeeping, tax, and cost reporting built for a licensed grower. A dispensary buys finished product and resells it. A cultivator produces the product, so every plant on the floor carries rent, power, labor, nutrients, and equipment wear that build up over weeks before the first sale.
That difference drives the federal tax bill. A producer can include much more of its spending in cost of goods sold (COGS) than a reseller can. Under Section 280E, COGS is the main cost an adult-use business can still subtract on its federal return. Growers who book their costs the way a store would often pay tax on money they never made.
Grow accountants also handle problems retail rarely sees: crop cycles, yield swings, plant waste, wholesale pricing, farm payroll, and state taxes charged at the first sale. See how this fits with our full range of cannabis CPA services.
You May Need a Grow Accountant If:
- Your federal tax bill looks far larger than your profit
- Your books expense grow-room rent and power instead of costing them into inventory
- You cannot say what one pound of flower costs you to produce
- Your Metrc counts and your inventory ledger disagree
- You hold medical and adult-use licenses, or grow in more than one state
Are your grow costs landing in COGS?

Batch & Yield Cost Reporting
We report cost per batch, per room, and per pound, so you can see which strains and harvests make money and which do not.
Outsourced CFO
We build crop-cycle cash forecasts, capital budgets, and pricing models for wholesale buyers. See our outsourced CFO services.
Audit Readiness
We keep the costing method, allocation schedules, Metrc reconciliations, and tax filings organized so an IRS or state review moves faster.
Section 471 COGS for Cannabis Growers
Section 471 of the Internal Revenue Code governs inventory. Treasury Regulation 1.471-3 sets two different cost rules. For goods a business buys, cost is mainly the invoice price plus the freight and other charges needed to take possession. For goods a business produces, cost includes raw materials, direct labor, and the indirect production costs needed to make the product.
Regulation 1.471-11 adds the full absorption method for producers. It lists indirect production costs such as repairs, maintenance, utilities, rent, indirect labor, and depreciation on production assets. A grower who follows it can move a real share of grow-room rent, lighting and HVAC power, cultivation labor, and equipment depreciation into inventory. Those costs then reach COGS when the crop sells.
Selling, marketing, and general office costs stay out. That line matters, so the allocation needs a clear basis, such as square footage for rent or metered usage for power.
Does Section 263A Apply?
Not for a business subject to 280E. In Patients Mutual Assistance Collective Corp. v. Commissioner, 151 T.C. 176 (2018), the Tax Court held that the uniform capitalization rules of Section 263A do not help a 280E taxpayer. Those rules only capitalize costs that would otherwise be deductible, and 280E makes them nondeductible. The Ninth Circuit affirmed in 2021. Growers therefore rely on Section 471 and the producer rules in Regulation 1.471-11, not 263A.
Indirect Grow Costs We Allocate
- Rent or occupancy cost for grow, dry, and cure rooms
- Electricity, water, and HVAC for production areas
- Wages for cultivation, trimming, and harvest staff
- Depreciation on lights, benches, and climate equipment
- Nutrients, growing media, and production supplies
- Repairs and maintenance on production assets
- Quality control and required lab testing
Batch Costing, Waste & Seed-to-Sale Reconciliation
Annual totals hide the story of a grow. We assign costs to each harvest batch as it moves from clone or seed through veg, flower, dry, cure, and packaging. When the batch is weighed, its cost spreads across the usable flower, trim, and biomass it produced. A strong harvest lowers your cost per pound. A failed one shows up as a clear loss instead of a hidden one.
Waste needs the same care. Plants and material destroyed under state rules leave inventory, and the records should show when, how much, and why. Clean destruction logs support the write-off and match what the regulator sees.
Most states require a seed-to-sale tracking system such as Metrc. We reconcile Metrc package and plant counts to your inventory ledger each month. Differences get investigated while they are still small, because a gap between the two is a common audit finding.
What Your Monthly Package Should Show
- Cost per pound by batch, room, and strain
- Work-in-process value for plants still growing
- Finished goods tied to Metrc counts
- Destroyed and wasted material, with dates and weights
- Medical and adult-use activity tracked separately
- State cultivation or wholesale tax owed and paid
280E and Schedule III for Cultivators in 2026
Section 280E blocks federal deductions for ordinary business expenses when a business traffics in a Schedule I or II drug. Adult-use cannabis is still Schedule I, so adult-use growers can only subtract COGS on the federal return. That is why the full absorption method is worth so much to a grower.
On April 28, 2026, marijuana under a state medical license moved to Schedule III. A cultivator that grows for the licensed medical market is no longer subject to 280E on that activity going forward. Treasury has said its forthcoming guidance will apply relief to the full tax year that includes the effective date. We are watching for that guidance.
Dual-license growers face the hardest work. Revenue and costs now need a documented split between medical and adult-use activity, by room, batch, or another defensible basis. Federal rescheduling of all cannabis is not settled either. A DEA hearing ran from June 29 to July 15, 2026 and was paused on September 29, 2026 pending a GAO report.
Dual-License Checklist
- Tag each batch as medical or adult-use at the start
- Pick an allocation basis for shared rooms and staff
- Track sales by license type in the ledger
- Document the method before the return is filed
- Revisit the split when federal guidance arrives
State Cultivation Taxes: Examples
Many states tax cannabis at the grower or wholesale level, often at the first sale or transfer. The rules below show how much they vary. Our cannabis tax rates by state guide covers more markets.
The Cannabis Cultivation Privilege Tax is 7% of gross receipts from the first sale of cannabis by a cultivation center or craft grower.
Since January 1, 2026, a 24% wholesale marijuana tax applies to the wholesale price of adult-use marijuana at its first sale or transfer to a retailer. Industry groups are challenging it in court, but it took effect on schedule.
Cultivation facilities owe a 15% wholesale excise tax on the first wholesale sale. Affiliate sales use the state's fair market value. Other sales use the actual sales price.
Since January 1, 2026, Class 1 cultivators pay a Social Equity Excise Fee of $2.50 per usable ounce of recreational cannabis sold or transferred, reported monthly on Form SF-100.
Retail marijuana carries a 15% excise tax at its first transfer from a cultivation facility. The tax base is the state's quarterly average market rate or the actual price, whichever applies.
California ended its cannabis cultivation tax for cannabis first sold or transferred on or after July 1, 2022. Growers there still face licensing costs and other state rules.
Payroll, CapEx & Cash Flow for Growers
Agricultural payroll. The IRS directs employers who pay wages to farmworkers to report federal withholding, Social Security, and Medicare on Form 943. Classifying cultivation staff correctly affects which return you file and how the labor flows into inventory. Our article on Form 943 for cannabis cultivators explains when it applies.
Capital spending and depreciation. Lights, HVAC, dehumidifiers, and buildouts cost a lot up front. Depreciation on production equipment can belong in inventory cost, so the asset records and the costing method need to agree. Read about common cultivation CapEx mistakes before your next expansion.
Seasonal cash flow. Cash goes out every day of a crop cycle and comes in only after harvest and sale. Outdoor growers may see one large harvest a year. We forecast cash by cycle so payroll and tax payments never catch you short.
Receivables. Wholesale buyers often pay late. Aging reports, credit limits, and steady follow-up protect your cash. See our cannabis accounts receivable guide.
Wholesale pricing and margins. With a true cost per pound, you know your floor price for each strain and grade. Our article on inventory accounting choices that affect margins shows where growers lose profit.

Cannabis Cultivation Accounting FAQs
What do grow accountants do?
Grow accountants keep the books for licensed cannabis cultivators, cost harvests into inventory, reconcile inventory to the state tracking system, prepare federal and state returns, and file cultivation or wholesale taxes. Many also provide CFO work such as crop-cycle cash forecasts and cost per pound reporting.
How do cannabis growers calculate COGS under Section 471?
Growers are producers, so Treasury Regulations 1.471-3(c) and 1.471-11 apply. Cost includes raw materials, direct labor, and indirect production costs such as grow-room rent, utilities, indirect labor, repairs, and depreciation on production equipment. Selling and general office costs stay out of inventory.
Does Section 263A apply to cannabis cultivators?
Not to activity subject to 280E. In Patients Mutual Assistance Collective Corp. v. Commissioner, 151 T.C. 176 (2018), the Tax Court held that Section 263A only capitalizes costs that would otherwise be deductible, so it does not help a 280E taxpayer. Growers rely on Section 471 and the full absorption rules instead.
What cultivation taxes do cannabis growers pay?
It depends on the state. Examples include Illinois's 7% cultivation privilege tax, Michigan's 24% wholesale marijuana tax since January 1, 2026, Nevada's 15% wholesale excise tax, Colorado's 15% excise tax on the first transfer, and New Jersey's $2.50 per ounce Social Equity Excise Fee. California repealed its cultivation tax as of July 1, 2022.
How does Schedule III affect cannabis cultivators?
Since April 28, 2026, marijuana under a state medical license is Schedule III, so 280E no longer applies to that medical activity going forward. Adult-use cannabis is still Schedule I, so 280E still applies to adult-use growing. Dual-license growers need a documented split of revenue and costs.
Do you work with multi-state cannabis cultivators?
Yes. We work with growers that hold licenses in more than one state. We handle each state's cultivation tax rules and consolidate reporting across facilities and entities so owners can compare results side by side.
