Does Oregon follow Section 280E?

Not fully. Section 280E still applies to your federal return, but Oregon allows licensed recreational businesses a subtraction on the Oregon return for expenses disallowed federally, which meaningfully reduces the Oregon side of the bill.

Is the 17% marijuana tax deductible?

It is a tax you collect from the consumer and remit to the state, so it is a liability rather than an expense. Treating it as revenue overstates your top line and distorts every margin figure downstream.

Do cannabis businesses owe Oregon Corporate Activity Tax?

Yes, if commercial activity exceeds the statutory threshold. Because CAT is calculated on receipts rather than income, it can be owed in a year the business shows a loss, which is why we model it quarterly.

Can you fix prior-year returns?

Often, yes. Missed Oregon subtractions, misclassified cost of goods sold and unreported CAT are the three issues we amend most frequently, subject to the statute of limitations for each year.

Cannabis Tax Planning Oregon | Federal, State & CAT Strategy

Cannabis Tax Planning Oregon — Federal, State and Local, Planned Together

An Oregon cannabis business faces at least four tax regimes at once: federal income tax distorted by Section 280E, Oregon income tax with its own treatment of disallowed expenses, the 17% marijuana retail tax plus local option, and the Corporate Activity Tax on commercial activity. Planning any one of them in isolation produces a bad answer.

Federal returns prepared from the costing, not around it

We prepare federal returns for C corporations, S corporations, partnerships and their owners directly from the inventory costing we maintain during the year. Cost of goods sold is supported by production records, payroll allocations and Metrc data rather than by a year-end percentage estimate that nobody can defend two years later.

The Oregon subtraction for federally disallowed expenses

Oregon decouples from Section 280E for licensed recreational businesses, allowing a subtraction on the Oregon return for ordinary business expenses that federal law disallowed. Retail wages, rent on non-production space, marketing and professional fees can therefore reduce Oregon taxable income even though they cannot reduce federal taxable income.

Claiming it correctly requires a clean bridge between the federal disallowance schedule and the Oregon return. We build that reconciliation as part of the engagement so the subtraction is documented if the Oregon Department of Revenue looks at it.

Marijuana retail tax and local option tax

Retailers collect 17% state marijuana tax, plus up to 3% local option where a city or county has adopted one — Portland, Salem, Eugene, Bend, Medford, Springfield and many others have. We keep those filings on schedule, reconcile them to point-of-sale data and to the general ledger, and make sure the liability is never mistaken for revenue in your margin reporting.

Corporate Activity Tax and quarterly estimates

The Oregon CAT applies to commercial activity above the statutory threshold and is calculated on receipts, not profit, which makes it particularly punishing for a high-revenue, thin-margin cannabis operation that has not planned for it. We model CAT alongside the federal 280E effect and set quarterly estimates that reflect both, so tax payments are funded rather than improvised.
