Congress Urges IRS to Clarify Tax Rules for Cannabis Businesses

Congressional lawmakers are demanding the IRS provide immediate tax guidance for cannabis businesses following the Trump administration's decision to reschedule marijuana to Schedule III.

Reps. Steven Horsford (D-NV) and Steve Cohen (D-TN) led a letter to federal officials emphasizing the urgent need for clarity. "State-legal cannabis businesses have been denied ordinary business tax deductions for far too long," the lawmakers wrote, pointing to the immediate impact rescheduling could have on thousands of operators.

The letter comes as the cannabis industry faces mounting questions about how the schedule change affects Section 280E of the tax code—the provision that has cost marijuana businesses billions in excess taxes over the past decade. Under current interpretation, cannabis companies operating under state law cannot deduct standard business expenses like rent, salaries, or marketing costs because marijuana remains federally illegal.

The 280E Problem

Section 280E has been the single largest financial burden for legal cannabis operators since California became the first state to legalize medical marijuana in 1996. The provision prohibits businesses trafficking in Schedule I or II controlled substances from claiming tax deductions.

Industry analysts estimate 280E costs cannabis businesses an effective tax rate of 70% or higher, compared to roughly 30% for comparable businesses in other sectors. A 2023 analysis by Whitney Economics found that cannabis operators paid approximately $1.8 billion in excess federal taxes in 2022 alone due to the provision.

But Schedule III substances—which now includes cannabis under the Trump administration's reclassification—are not subject to 280E restrictions. That technical distinction could fundamentally reshape cannabis business economics overnight.

What Operators Need to Know

The congressional letter highlights several specific areas where businesses need immediate guidance. Chief among them: when exactly can cannabis companies begin claiming standard business deductions?

"The industry is in limbo right now," said Rachel Gillette, executive director of Colorado's Cannabis Business Alliance. "Our members are asking whether they should amend 2024 tax returns, how to handle Q1 2025 filings, and what documentation they need to support these deductions."

The IRS has not yet issued formal guidance on how rescheduling affects 280E compliance. Tax professionals advising cannabis clients say the silence creates significant risk—both for businesses that claim deductions too early and those that wait too long and overpay.

Andrew Kline, a cannabis tax attorney with Perkins Coie, notes that the effective date of rescheduling remains unclear. "Does 280E relief begin when the DEA published its final rule? When that rule takes effect? Or when the scheduling change is formally complete? These aren't academic questions—they have million-dollar implications for our clients."

Industry Response

Cannabis trade organizations have amplified the congressional call for clarity. The National Cannabis Industry Association sent its own letter to Treasury Secretary Scott Bessent last week, requesting expedited guidance.

"This is the most significant tax development in cannabis industry history," said NCIA CEO Aaron Smith. "But without clear direction from the IRS, businesses are flying blind on compliance."

Some larger multi-state operators have already begun adjusting their tax strategies in anticipation of 280E relief. Curaleaf Holdings, one of the nation's largest cannabis companies, mentioned potential tax savings in its most recent earnings call. CFO Ed Kremer estimated the company could see $50-70 million in annual tax relief once 280E no longer applies.

Smaller operators, however, lack the resources to take aggressive tax positions without explicit IRS approval. "We can't afford to guess wrong on this," said Maria Santos, owner of a family-run dispensary in Nevada. "We need the IRS to tell us exactly what we can and cannot deduct, and when."

What Happens Next

The congressional letter requests a response within 30 days, though the IRS is not legally bound to that timeline. Tax guidance typically goes through multiple review stages and can take months to finalize.

Policy experts suggest the IRS may issue interim guidance—possibly in the form of a notice or revenue ruling—while developing more comprehensive regulations. Such interim guidance could provide safe harbors for businesses to begin claiming deductions while formal rules are drafted.

The lawmakers' letter also raises questions about retroactive relief. Could businesses that overpaid taxes in previous years due to 280E file amended returns? The answer could unlock billions in refunds for an industry that has operated under severe tax disadvantages since its inception.

For now, cannabis businesses are left weighing risk against potential reward. Every day without guidance means continued tax uncertainty—and potentially millions in either overpaid taxes or future penalties.
