Montana passed HB 788 in 2023, decoupling from IRC §280E for state income tax purposes starting in 2024. Montana cannabis operators can now deduct ordinary business expenses on their MT state return — but federal 280E still applies. Dual-method accounting is required, and 420Ledger is built for exactly this complexity.
Book a Free ConsultationMontana's 280E decoupling is a significant financial benefit for MT operators — but it introduces accounting complexity that requires precise dual-method bookkeeping. 420Ledger structures Montana cannabis books to capture the full benefit of state decoupling while maintaining federal 280E compliance.

Montana is one of only a handful of states that has formally decoupled from federal IRC §280E. Starting January 1, 2024, Montana cannabis operators may deduct ordinary and necessary business expenses on their Montana state income tax return — including rent, wages, marketing, professional fees, and other expenses that federal 280E disallows.
Federal 280E still applies in full. Montana operators must still prepare their federal returns under 280E rules — maximizing COGS and accepting the disallowance of other operating expenses at the federal level. The state-level decoupling only reduces your Montana income tax burden.
Yes. Montana passed HB 788 (2023), which decoupled from IRC §280E for Montana state income tax purposes, effective for tax years beginning January 1, 2024. Montana cannabis operators can deduct ordinary and necessary business expenses on their MT state return — even though federal 280E still applies and disallows those deductions on the federal return. This requires maintaining dual-method accounting.
Yes. Federal IRC §280E still applies to Montana cannabis operators regardless of the state decoupling. Montana operators must still prepare federal returns under 280E rules — maximizing COGS and accepting the disallowance of other business expenses at the federal level. The MT state decoupling only affects your Montana state income tax return.
Montana imposes a 20% cannabis tax on adult-use retail sales. There is no separate state sales tax on cannabis. Medical cannabis is taxed at a lower rate (4%). The 20% retail rate must be tracked and remitted to the Montana Department of Revenue.
Montana's 280E decoupling requires dual-method accounting: your books must support both a federal calculation (280E applies, COGS only deductible) and a Montana state calculation (all ordinary business expenses deductible). Your chart of accounts must clearly separate COGS from other operating expenses, and your accountant must prepare two separate income calculations at tax time.
Montana is one of only a handful of states that has decoupled from federal 280E for state tax purposes — a significant financial benefit for MT operators. Combined with a 20% flat adult-use retail cannabis tax and no separate state sales tax on cannabis, Montana's structure is unique and requires an accountant who understands both the federal 280E calculation and the state-decoupled calculation. Most general accountants are not equipped for this.
Flat monthly rates. All plans include federal 280E analysis, MT state decoupling calculation, monthly close, and MT tax tracking.
Montana's 280E decoupling is a real tax benefit — but only if your books are structured to capture it. Let 420Ledger set up your dual-method accounting correctly.
