Lawmakers Push California Marijuana Tax Hike Extension

California lawmakers are advancing a plan to delay the state’s controversial marijuana tax increase, offering temporary relief to licensed cannabis businesses already facing stiff competition from the illicit market. The proposed California marijuana tax hike extension, introduced by Assembly member Matt Haney, passed a key Senate committee this week and would postpone the new excise rate until October. Although the higher tax rate officially took effect on July 1, supporters of the bill argue the industry needs more time to stabilize.

California Senators Back Five-Year Cannabis Tax Freeze

California lawmakers are moving to pause the state’s controversial marijuana excise tax increase, which took effect on July 1. A key Senate committee has approved Assembly Bill 564, a measure that would delay implementation of the 4% tax hike for five years in a move supporters say is essential to keeping the legal market alive.

The California marijuana tax hike extension, sponsored by Assembly member Matt Haney (D-San Francisco), passed the Senate Revenue and Taxation Committee in a 5-0 vote on Wednesday. While the bill won’t undo the tax increase that just took effect, it would push the next scheduled hike back to October and reset the framework for future adjustments.

“California has not given the legal cannabis industry a chance to grow into its potential,” Haney told the committee, warning that high taxes are driving consumers back to the illicit market. “The legal industry needs a lifeline.”

Cannabis Tax Rate Jumps Despite Broad Pushback

The state’s cannabis excise tax rose from 15% to 19% on July 1 under a recent budget measure. Haney and other lawmakers had pushed to include his tax freeze proposal in the budget itself, which would have made the California marijuana tax hike extension effective immediately. But Senate leadership declined to include it.

Senate President Mike McGuire (D-Healdsburg) said that while he agrees the cannabis tax structure has failed, freezing the rate could create budget gaps for programs funded by marijuana revenue. Those programs include community reinvestment grants, law enforcement training, and substance use education.

Despite that pushback, the standalone bill is gaining traction. It now moves to the full Senate for further consideration.

How the Extension Would Work

Under the proposed California marijuana tax hike extension, the state would revise how it sets the cannabis excise rate. Instead of using a fixed percentage, the California Department of Tax and Fee Administration (CDTFA) would work with the Department of Finance to estimate how much revenue the previous year’s tax generated. The goal is to collect a similar amount going forward, without increasing the burden on legal operators.

The bill also requires CDTFA to file an annual report beginning December 1, 2026. That report would show the gain or loss in cannabis tax revenue due to the delayed hike. Lawmakers say this approach balances the need for tax stability with the state’s ongoing budget concerns.

Legal Industry Cites Growing Pressure

California’s legal marijuana businesses have long warned that they are overtaxed and overregulated. In many parts of the state, local taxes and licensing fees stack on top of state excise taxes, making legal products far more expensive than illicit ones.

Supporters of the California marijuana tax hike extension argue that the state’s legal operators are being squeezed out, despite being the only ones paying into public health and community programs. Haney said his bill is about giving these businesses a fair shot at survival.

State Continues Using Marijuana Revenue for Public Programs

Even as lawmakers debate the excise tax rate, California continues to invest cannabis tax dollars in social equity and community initiatives. In June, the Governor’s Office of Business and Economic Development awarded $52 million in grants to nonprofits and local health agencies. These grants are part of the California Community Reinvestment Grants program, now in its seventh round.

The state is also seeking new research proposals to evaluate the long-term impacts of cannabis legalization. Officials say these efforts will help inform future policy decisions, including those related to taxation.

Conclusion

With the new excise rate already in place, the California marijuana tax hike extension may not offer immediate relief. Still, the bill signals growing recognition that the state’s legal cannabis industry is nearing a tipping point. If lawmakers want to keep licensed businesses afloat and protect long-term tax revenue, stabilizing the current system is a necessary first step. Whether AB 564 becomes law this fall could determine the future shape of California’s legal marijuana market.
