Cannabis Businesses Face Uncertainty Over Retroactive 280E Tax Relief After Rescheduling

The recent decision by Acting Attorney General Todd Blanche to reschedule medical marijuana to Schedule 3, while leaving adult-use cannabis on Schedule 1, has sparked widespread debate across the cannabis industry regarding the future of Section 280E tax obligations. As reported by MJBizDaily, this move has created a glimmer of hope for cannabis businesses long burdened by excessive tax bills, but major questions remain about when and how relief might be applied, including the possibility of retroactive refunds

For years, cannabis accountants and legal experts have speculated that Section 280E relief would only apply prospectively following federal rescheduling. However, the latest order encourages the Secretary of the Treasury to consider providing retrospective relief from Section 280E for years in which operators held qualifying medical marijuana licenses. This has led many in the sector to argue that, logically, if marijuana now qualifies as a Schedule 3 substance, "280E never should have applied." Yet, as the article notes, the logistical and administrative hurdles for the IRS to process potentially billions in refunds are significant

The financial stakes are substantial. Citing a Whitney Economics study, MJBizDaily reports that the cannabis industry has paid approximately $15 billion in excess 280E taxes since 2018 alone, with companies publicly acknowledging at least $1.6 billion in taxes they believe are not owed. Despite this, the Treasury and IRS have not yet indicated whether they will allow for retroactive relief, only confirming that any changes will likely begin with the 2026 tax year. This leaves operators in a state of limbo, unsure whether they can reclaim prior payments or must simply look forward to future tax relief

Eligibility for retroactive relief depends heavily on the statute of limitations for tax filings. Generally, businesses have three years from the date of filing or two years from the date of payment to amend returns and seek refunds. As the article highlights, "if a taxpayer did not take some action to preserve the statutes, such as filing a protective claim or perhaps taking the leap and filing an amended return, that taxpayer has lost its ability to claim a refund of any overpaid tax." The complexity deepens for dual licensees in adult-use states, as regulatory guidance is still pending on how to allocate expenses between medical and adult-use operations

Industry experts caution that, while awaiting official guidance, cannabis operators are not entirely powerless. Businesses can challenge the IRS’s interpretation of 280E by meeting the "reasonable basis standard," which requires positions to be supported by recognized tax authorities. Even if unsuccessful, such positions can protect taxpayers from penalties if they act in good faith with proper documentation. As one legal expert cited by MJBizDaily explained, "Reasonable basis is not unilaterally determined by the IRS, and a position can indeed meet the standard even if the IRS claims it does not."

From OG Lab’s perspective, the evolving tax landscape for cannabis businesses underscores the importance of proactive legal and financial strategies. The potential for retroactive 280E relief could reshape industry profitability and level the playing field for medical operators, but significant uncertainties remain, especially for adult-use businesses. Industry participants should closely monitor forthcoming IRS and Treasury guidance, as well as ongoing litigation, as the outcome will have far-reaching implications for the entire sector
