280E Accounting & Tax Compliance for Michigan Cannabis Businesses

280E accounting is the discipline of producing accounting records that can support a cannabis company's federal tax position. It is not a filing service and it is not a strategy sold separately from the books. Where Section 280E applies, the tax outcome a business reports is a direct function of how transactions were recorded, how inventory was accounted for, how costs were classified, and whether the resulting numbers can be traced to evidence.

That makes cannabis tax compliance inseparable from bookkeeping, inventory accounting, cost accounting, cost of goods sold support, the chart of accounts, supporting documentation, tax workpapers, return preparation and cash planning. Each of those is a link in one chain, and the chain is only as strong as the weakest link in it.

Nothing on this page is legal advice, and no accounting method is presented as universally correct. Federal cannabis tax treatment should be evaluated based on current law and the taxpayer's specific facts. What we can commit to is a record that is complete, consistent, reconciled and documented — the conditions under which any tax position, whatever the applicable treatment, can actually be defended.

Section 280E is a provision of the Internal Revenue Code that can disallow the deduction of certain ordinary and necessary business expenses for a trade or business found to consist of trafficking in a controlled substance within the meaning of the statute. Where it applies, cost of goods sold generally remains part of the computation of gross income while other categories of expense may be limited.

Applicability, scope and current federal treatment are legal and tax questions that turn on current authority and a taxpayer's own facts, and they should be evaluated with an advisor at the time of filing rather than assumed from a general statement. For a fuller educational treatment of the provision, its background and how it is commonly discussed, see 280E Explained. This page covers the commercial accounting work.

A 280E accountant makes the financial record capable of supporting the tax position. Depending on scope and applicable law, an engagement may include:

• Reviewing the chart of accounts against the business model
• Reviewing bookkeeping structure and coding consistency
• Reviewing inventory accounting and costing methodology
• Supporting cost of goods sold calculations with records
• Reviewing cost classifications against underlying facts
• Maintaining supporting schedules through the year
• Preparing tax workpapers that tie to the ledger
• Coordinating the books with return preparation
• Identifying unsupported balances and classifications
• Improving documentation and written accounting policy
• Supporting estimated-tax planning during the year
• Helping management understand tax cash requirements

Not every engagement includes all of this. Scope is set after reviewing the entity structure, the current books, the inventory system and prior workpapers. Some operators need a full rebuild; others need a review, a documentation layer and a recurring workpaper process.

Most cannabis tax problems are not tax problems. They are bookkeeping problems that were not visible until a return had to be filed. The failure sequence is consistent:

The constructive version of the same chain is what a functioning engagement builds and then maintains every month:

Year-end tax work becomes materially more difficult when monthly books have not been reconciled. Recurring accounting is the foundation of the whole discipline — see cannabis bookkeeping for how that monthly cycle is run.

The chart of accounts is the instrument that decides what a business can later prove. An account structure built for a generic small business collapses categories that a cannabis operator needs kept apart, and once a year of activity has been coded into it, separating those categories retroactively is expensive and often incomplete.

A workable structure should make it possible to distinguish the material financial categories needed for management reporting, inventory accounting, cost of goods sold, tax workpapers, expense analysis and reporting by location or entity. In practice that usually means deliberate treatment of:

• Revenue, by channel and location where relevant
• Inventory, by stage and by location where relevant
• Cost of goods sold, with supporting detail behind it
• Operating expenses, separated by function
• Payroll, coded by department and activity
• Rent and occupancy, by facility
• Professional fees and administrative cost
• Tax liabilities, by tax type and jurisdiction
• Fixed assets and accumulated depreciation
• Intercompany accounts where multiple entities exist

There is no universal cannabis chart of accounts, and any template presented as one should be treated with suspicion. Structure follows business model: a single-site retailer, a vertically integrated operator and a processor selling wholesale need different levels of detail in different places.

One practitioner point matters more than the rest. Account name does not determine tax treatment. Moving an expense into an account labeled “COGS” does not, by itself, change how that cost should be treated. The underlying facts, the accounting treatment and applicable law are what matter; the account is only where the result is recorded.

Cost classification is the center of gravity for this work. Every dollar a cannabis business spends has to be recorded somewhere, and where it lands determines whether the financial statements describe the business accurately and whether the tax workpapers have anything to stand on. Classification should follow the actual nature of the cost and the appropriate accounting and tax treatment for it — never the treatment that would be convenient.

The categories a cost accountant works through conceptually include inventory-related costs versus period expenses; direct costs versus indirect costs; production-related costs where a production process exists; retail operating costs where the activity is distribution rather than production; payroll; occupancy; purchasing; freight; and packaging where it is properly part of the product rather than a selling cost.

No category is automatically capitalizable and none is automatically deductible. The same expense description can require different treatment at two different companies because the activity behind it differs. What a good system produces is not an aggressive answer but a consistent, documented one that a reviewer can follow.

Cost of goods sold is where accounting and tax meet most directly. It is an accounting measure of the cost of inventory sold during a period, and it can only be as reliable as the inventory and cost records behind it. Where Section 280E applies, that number carries more weight because other expense categories may be limited — which is exactly why it attracts scrutiny and why it has to be supported rather than derived.

This is a conceptual accounting framework, not a universal tax formula for every cannabis business. What may properly enter each element depends on the business model and applicable law, and the amounts must reconcile to inventory records.

In practice, cost of goods sold is affected by the business model, the inventory method in use, purchasing practices, production activity, labor where applicable, overhead treatment where applicable, the quality and frequency of inventory counts, adjustments and write-offs, the costing method chosen and applied consistently, and the documentation standing behind all of it.

A cost of goods sold figure that swings sharply from month to month with no operational explanation is almost always an inventory or costing problem rather than a margin story. Diagnosing that is ordinary accounting work, and it usually has to happen before any tax conversation is worth having.

A retailer's cost structure is comparatively simple to describe and surprisingly hard to prove. Product is purchased, received, held as inventory, sold through a point-of-sale system, and relieved into cost of goods sold. Everything else — staffing the floor, rent, marketing, security, software, delivery — sits outside that chain as operating cost.

The accounting work is proving each arrow: that purchases were received and priced correctly, that inventory on the ledger matches what is actually on the shelf, that recorded sales agree with tender and deposits, and that cost of goods sold reflects units actually sold at costs actually paid.

Retail operators should not assume every operating cost can be moved into cost of goods sold. Relabeling a period expense does not change what it was, and a tax workpaper built on relabeling is the easiest kind to unwind. The retail-side mechanics — point-of-sale, cash, shift and deposit reconciliation, inventory and store-level reporting — are covered on dispensary accounting.

Cultivation is a production business, and production businesses require cost accounting rather than expense tracking. Plants move through stages, costs are incurred continuously against a crop that is not yet finished goods, and the harvest event converts accumulated cost into inventory that will eventually be sold or transferred.

The concepts a cultivator's accounting has to handle include production activity by stage and by room or batch; direct production costs such as nutrients, media and consumables; indirect production costs where appropriate; labor associated with cultivation activity; facility costs including utilities and occupancy allocated on a documented basis; inventory stages from immature plant through growing crop; harvest and the transition to finished inventory; and the costing method used to value it.

There are no blanket capitalization rules here, and cultivation payroll is not automatically cost of goods sold. Treatment depends on the facts of the activity and applicable law. What the accounting system contributes is a defensible record of what was spent, on what activity, and how it was allocated. See cultivation accounting and the cultivator practice for the operational side.

Processing adds a transformation step, and transformation is where inventory accounting gets genuinely technical. Raw biomass and other production inputs enter, labor and overhead are applied, work in process exists at any point in time, yield determines how much finished product results, and finished goods carry the accumulated cost forward until sale.

The accounting record must address raw materials and production inputs, labor applied to production, production overhead where appropriate and allocated on a documented basis, work in process concepts across runs and batches, yield and its variance, the transition to finished goods, the inventory costing method applied, packaging where it is properly a product cost, and the documentation that ties all of it together.

Yield documentation is often the weakest point in a processor's records and the first thing a reviewer asks about. Two runs producing different output from similar input is normal; being unable to show why is not. More on manufacturing accounting, the manufacturer and processor practices.

Inventory is where most cannabis accounting engagements either succeed or quietly fail. The difficulty is that four different views of “inventory” exist in a licensed operation at all times, and they are related without being interchangeable.

Inventory quantity and accounting inventory value answer different questions, and both may require reconciliation. A count that matches the operational system tells you nothing about whether the balance sheet is right; a ledger balance that looks reasonable tells you nothing about whether the product exists. The engagement has to connect them and keep them connected, with variances investigated in the period they arise rather than accumulated into a year-end adjustment nobody can explain.

Operational track-and-trace data is valuable to the accounting record precisely because it is maintained independently for a different purpose. Reconciling it against the ledger tests whether accounting inventory is grounded in reality. It does not, by itself, determine tax treatment.

Where reconciliation breaks, the cause is usually mundane: timing differences, unposted transfers, waste and destruction not reflected in the ledger, packaging conversions, returns, or costing applied to the wrong units. Working those items is described in detail on Metrc reconciliation. We are an independent accounting firm and are not affiliated with, endorsed by, or acting on behalf of any track-and-trace provider or government agency.

Recurring bookkeeping is what makes everything above possible. Consistent coding against a deliberate chart of accounts, inventory entries posted as activity occurs, payroll entered from the register rather than the bank feed, reconciliations completed monthly, a real month-end close, and supporting schedules maintained through the year instead of assembled in March.

Attempting to “fix 280E” only at year-end is a fundamentally harder job when the underlying books are poor. Twelve months of ambiguous coding cannot be resolved from memory, and the records needed to resolve it — receiving documents, count sheets, time detail — are often the first things to disappear. The monthly cycle is described on cannabis bookkeeping.

Payroll is usually one of the largest costs in a cannabis business and one of the most carelessly recorded. The accounting objective is narrow and factual: the general ledger should reflect what was paid, to whom, for what activity, at which location, with employer costs and liabilities recorded correctly.

• Journal entries posted from the payroll register, not the bank feed
• Department and location coding that reflects actual work performed
• Production versus non-production activity distinguished where factually relevant
• Employer payroll taxes and benefit costs recorded separately
• Payroll liability accounts reconciled each period
• Time detail retained to support any allocation applied

Tax treatment of payroll depends on facts and applicable law. Cultivation payroll is not automatically cost of goods sold, and dispensary payroll is not automatically non-deductible. Coding it accurately is an accounting requirement; characterizing it for tax purposes is a separate determination made against current law. See cannabis payroll.

A tax position should be supportable from the underlying records without narrative reconstruction. Documentation is what turns a number in a workpaper into something a reviewer can verify.

• General ledger detail for the periods presented
• Invoices and vendor purchase records
• Receiving documentation tied to purchases
• Inventory reports, counts and cycle count records
• Payroll records and registers with department detail
• Cost schedules supporting inventory valuation
• Written allocation methodology where allocation is applied
• Reconciliation workpapers for material accounts
• Supporting tax schedules for each material adjustment
• Written accounting policies applied consistently
• Period-close support and adjusting entry documentation
• Fixed-asset schedules and depreciation support

Documentation supports a tax position; it does not convert an unsupported position into a valid one. A thick file behind a classification that does not reflect the underlying facts is not protection. The purpose of the documentation layer is to make a correct position verifiable, not to make a doubtful one look settled.

Workpapers are the structured bridge between accounting records and the return. They exist so that every material figure on a filing can be followed back to a schedule, and every schedule back to the ledger.

A workable workpaper set includes the trial balance as presented, inventory records and valuation support, the cost of goods sold computation with its components, each tax adjustment with its basis, supporting schedules for material balance-sheet accounts, and a clear reference trail between them. Each material adjustment should be traceable to support — if a number cannot be sourced, it is not finished.

Tax workpapers should reconcile back to accounting records. When they do not, one of two things is true: the books changed after the workpapers were prepared, or the workpapers were never built from the books in the first place. Both are worth finding before a filing rather than after.

• Inventory balances and valuation
• Cost of goods sold components
• Payroll expense and liabilities
• Fixed assets and accumulated depreciation
• Tax liability accounts by type
• Intercompany accounts across entities
• Cash and bank balances
• Year-end and audit adjusting entries

Monthly discipline is the cheapest form of tax readiness available. Closing every month keeps variances inside a thirty-day window where the people who can explain them are still available and the source documents still exist.

The recurring cycle itself is delivered through cannabis bookkeeping, with reporting output covered under financial reporting.

Year-end tax work is easier, faster and cheaper when records have been maintained throughout the year. Before workpapers begin, the following should be in place:

• Books closed through the final period
• All bank accounts reconciled
• Inventory reconciled and valued with support
• Cost of goods sold supported by cost schedules
• Payroll support complete, including registers
• Fixed-asset schedule current with additions and disposals
• Tax liability accounts reconciled by type
• Entity and intercompany accounts reconciled
• Adjusting entries documented with rationale
• Complete general ledger available for the year
• Trial balance agreeing to the financial statements
• Supporting workpapers organized and referenced

Planning here means visibility and preparation, not schemes. The useful work is estimating taxable income during the year rather than after it, confirming that cost of goods sold support is being built as activity occurs, projecting expected tax obligations under applicable law, setting cash reserves against them, maintaining entity-level financial visibility where multiple entities exist, understanding how inventory decisions affect reported results, and considering the timing of major expenditures from a cash-planning perspective.

We do not present abusive tax-avoidance strategies and we do not imply guaranteed tax savings. Where planning changes an outcome, it is because the accounting supported a correct treatment that would otherwise have gone undocumented, or because management made an operational decision with accurate information in front of them.

Accounting profit and available cash can diverge materially in this industry, and where Section 280E applies that gap can be severe. A business can be profitable on paper, current on every obligation, and still be unable to fund a tax payment it did not model.

The forecast has to hold estimated payments, working capital needs, inventory purchasing cycles, payroll, debt service and planned capital spending in the same view. Where Section 280E applies, expected tax obligations should be included in cash-flow planning rather than treated as a year-end surprise. Forward-looking work lives in cash flow planning and fractional CFO services.

Accounting and return preparation are separate functions that have to be coordinated. The accounting side produces a closed, reconciled, documented record; preparation takes that record and files against current law.

Return preparation itself — filings, elections, deadlines and coordination with federal and state returns — is handled under cannabis tax preparation.

Federal income-tax treatment and Michigan state tax obligations are separate layers of compliance. A federal position under Section 280E does not determine state filing requirements, and state obligations continue regardless of how the federal question resolves. Both should be planned together for cash purposes and kept distinct for compliance purposes.

Michigan-specific rates, filings and administration are covered in the Michigan Cannabis Tax Guide, with transactional filing work under sales tax compliance.

Entity structure affects accounting, reporting, intercompany activity and tax administration, and those effects are real. What structure is not is a magic solution. A management company or a real-estate entity does not automatically change how any activity is treated; substance, actual operations and applicable law govern.

We do not advocate artificial entity splitting and we do not provide legal advice. Where multiple entities already exist, our role is to make each one's books stand on their own, ensure intercompany activity is recorded on both sides, and produce entity-level and consolidated reporting that reconciles. Structuring considerations from an accounting standpoint are discussed under entity structuring, and should be reviewed with qualified legal counsel.

Operators running several locations need comparability before they need consolidation. That means one standard chart of accounts, consistent location coding, inventory tracked by location, cost of goods sold determined by location, shared expenses allocated on a documented basis, payroll coded to the location where work occurred, and workpapers that can be assembled from comparable data.

Consolidated workpapers do not imply that each location files separately; filing structure follows the legal entity structure, not the store count.

Where several legal entities exist, each needs its own complete set of books, its own trial balance, and its own supporting schedules. Intercompany transactions must be recorded on both sides and reconciled; shared costs must be allocated on a documented and consistently applied basis; inventory must be tracked separately where it is separately owned; and tax workpapers must be prepared at the entity level even when management reporting is consolidated.

Intercompany balances that do not agree are one of the most common findings in a multi-entity cleanup and one of the most disruptive to resolve late. Operators running across state lines should also see the multi-state operator practice.

A large share of engagements begin with records that are not in a condition to support anything. Common findings include books months behind, inventory that will not reconcile, unsupported cost of goods sold, an inconsistent chart of accounts, operating expenses mixed with inventory costs, unclear payroll classification, stale balance-sheet accounts, prior tax workpapers that do not tie to the books, intercompany accounts that do not reconcile, and multiple stores or entities recorded together.

Scope is set only after reviewing what actually exists: bank statements, purchasing and receiving records, inventory reports, payroll registers, prior returns and the current ledger. Historical records cannot always be perfectly reconstructed. Where they cannot, the honest outcome is a documented, reasonable position with its limitations stated — not an invented one.

COGS changes dramatically every month.

Investigate inventory valuation, timing of purchase and receiving entries, costing method consistency, and whether adjustments are being posted to COGS rather than investigated.

Inventory doesn't tie to the general ledger.

Compare counts, operational records and the subledger against the ledger balance, then work the differences by category: timing, transfers, waste, conversions, returns and costing errors.

Tax workpapers do not tie to the books.

Determine whether the ledger changed after preparation or the workpapers were built independently, then rebuild the reference trail from trial balance forward.

Payroll is classified inconsistently.

Review the payroll register against department and location coding, confirm entries post from the register, and check whether time detail exists to support any allocation.

Expenses are moved into COGS without support.

Trace the underlying facts of each reclassified cost; account name does not determine treatment, and unsupported reclassification is a risk rather than a benefit.

The chart of accounts is too generic.

Map the account structure against the business model and identify which material categories cannot currently be separated for reporting or workpaper purposes.

Balance-sheet accounts haven't been reconciled.

Build supporting schedules for each material account, identify stale balances, and document the basis for correcting entries.

We only review 280E at tax time.

Move classification and cost support into the monthly close so the year-end position is assembled from maintained records rather than reconstructed.

Different locations use different accounting methods.

Standardize the chart of accounts and costing approach, then restate for comparability before attempting consolidated reporting or workpapers.

Intercompany balances don't match across entities.

Reconcile each intercompany pair, confirm both sides of every transaction were recorded, and establish a recurring monthly intercompany reconciliation.

No two engagements are identical. A single-site retailer with current books and a vertically integrated operator two years behind need very different sequencing, and the process above is a framework rather than a fixed program.

We support licensed cannabis operators across Michigan, working remotely with management teams in Detroit, Grand Rapids, Ann Arbor, Lansing, Flint, Kalamazoo, Sterling Heights, Warren, Troy and Dearborn, as well as cultivation and processing facilities in smaller markets across the state.

Engagements are delivered remotely; we do not maintain branch offices in these markets. Michigan-specific accounting context is collected in the Michigan Cannabis Accounting Guide.
