California Increases Excise Tax Despite Industry Pushback
Effective July 1, 2025, California raised its cannabis excise tax from 15% to 19%. This move came after a proposed bill to freeze tax rates—backed by Governor Gavin Newsom—failed to gain traction in the legislature. The tax hike is meant to recoup lost revenues following the state’s 2022 elimination of the cultivation tax, a move initially intended to support licensed growers and shift consumer demand away from illegal operators.
Despite these intentions, industry leaders have criticized the tax increase, arguing that it places an additional burden on legal businesses already struggling to compete with the state’s persistent and robust illicit market. The United Cannabis Business Association and other advocacy groups have warned that the higher taxes could push more consumers to unlicensed sellers, further undercutting the regulated industry.
California’s cannabis market—one of the largest in the world—has long grappled with overregulation and high operational costs. The latest tax hike is seen by many as a step backward in efforts to stabilize the legal market and transition users away from unregulated channels.
Minnesota Raises Taxes Before Market Launch
Minnesota, which legalized adult-use cannabis in 2023, has yet to launch commercial sales but has already increased its planned excise tax from 10% to 15%. The change was introduced as part of broader fiscal legislation aimed at balancing the state’s budget ahead of retail market rollout, now expected in 2025 or early 2026.
The decision has sparked concern among entrepreneurs and policy experts, who argue that preemptive tax increases could discourage investment and reduce the competitiveness of legal products. With a still-developing regulatory framework and no established consumer base, analysts warn that higher taxes could make it more difficult for Minnesota’s legal market to establish a foothold once sales begin.
Critics also point out that new cannabis markets require competitive pricing in their early stages to successfully draw consumers away from unregulated sources—a point many believe is being overlooked in Minnesota’s fiscal planning.
Maine Imposes Incremental Tax Hike
Maine, which began adult-use cannabis sales in 2020, raised its excise tax from 10% to 14% in an effort to bolster state revenues. While the increase is relatively modest compared to California’s, industry participants in Maine have echoed concerns about the long-term impact of higher taxes on market stability and growth.
Operators in Maine warn that tax increases—especially without corresponding support for business development or enforcement against illegal sellers—could stall momentum in the state’s cannabis sector. Some smaller businesses fear the added tax burden may tip the scales in favor of larger, better-capitalized firms, reducing competition and limiting consumer choice.
National Context and the Elusive “Ideal” Tax Rate
The tax increases in these three states reflect a broader national challenge: determining the “ideal” cannabis tax rate that supports public revenues without undermining the legal industry. States have adopted widely varying tax models, ranging from flat percentage rates on retail sales to weight-based and potency-based taxes. However, there is still no consensus on which model best balances revenue generation with market sustainability.
High tax rates have consistently been linked to the resilience of illicit cannabis markets, especially in jurisdictions where enforcement is limited and legal products are more expensive. Policymakers are under increasing pressure to calibrate tax policy to reflect market conditions, public health concerns, and fiscal needs.
Outlook
As more states look to cannabis as a source of tax revenue, the experiences of California, Minnesota, and Maine will likely serve as key case studies. Their varying approaches and the outcomes of their tax decisions will inform future legislative efforts across the country.
