LANSING — Michigan Treasury officials are pushing back against claims that the state’s new 24% wholesale marijuana tax is underperforming, arguing that it is simply too early to judge a tax that took effect less than six months ago. The Michigan 24% marijuana tax has become a flashpoint since it took effect earlier this year.
The comments come as Michigan’s cannabis industry continues a legal battle seeking to overturn the tax, a dispute that has been fast-tracked to the Michigan Supreme Court.
Michigan 24% Marijuana Tax: By The Numbers
- 24% wholesale marijuana tax took effect Jan. 1, 2026.
- Lawmakers projected the tax would generate roughly $420 million annually for road funding.
- Michigan cannabis consumers purchased more than $715 million in marijuana products during the first quarter of 2026.
- Treasury collected more than $34 million in wholesale marijuana tax revenue during the first quarter.
Treasury officials said early collection figures should not be used to draw conclusions about the long-term performance of the tax.
“The Wholesale Marijuana Tax is a complex tax,” Treasury said in a statement provided to MITechNews. “Our goal was to bring industry stakeholders to the table right from the beginning so we can collectively create a tax system that is fair and equitable for all taxpayers.”
Treasury added that several factors affect the collection of any newly implemented tax and cautioned against annualizing first-quarter results.
“It is far too early to draw any conclusions about the revenue it will generate based on first quarter collections,” the department said.
State Still Expects Significant Road Funding
The wholesale marijuana tax was approved last year as part of a broader road funding package championed by Gov. Gretchen Whitmer and legislative leaders.
Supporters argued that Michigan’s rapidly growing cannabis industry should contribute additional funding to transportation infrastructure.
Treasury emphasized that the state’s legal cannabis market remains one of the largest in the nation.
According to the department, Michigan recorded more than $715 million in retail cannabis sales during the first three months of 2026.
“Once the tax on wholesale ramps up and collections begin in full, the tax will provide a significant boost for road funding,” Treasury said.
Industry Continues Constitutional Challenge Over Michigan 24% Marijuana Tax
While Treasury is defending the tax’s revenue potential, the cannabis industry continues to challenge its legality.
The Michigan Cannabis Industry Association and several operators have filed lawsuits arguing that lawmakers improperly amended Michigan’s voter-approved marijuana law.
Industry attorneys contend the Legislature failed to obtain the three-fourths supermajority vote required to amend a voter-approved initiative under the Michigan Constitution.
A separate lawsuit challenges the structure of the tax itself.
Those cases remain active and are headed to the Michigan Supreme Court for a decision.
What’s Next?
The state’s defense of the tax sets up an increasingly important debate over both its financial impact and constitutional validity.
Treasury maintains the tax needs more time before its success can be evaluated.
Industry groups argue the levy is harming an already struggling market facing falling prices, oversupply and shrinking profit margins.
For now, the state’s newest cannabis tax remains in effect, generating road funding while its future is debated in both the marketplace and the courts.
Conclusion:
The Michigan 24% marijuana tax still faces an uncertain future. Treasury officials say early revenue numbers are not enough to judge the tax’s success. However, industry groups warn the levy is hurting an already struggling market. Meanwhile, constitutional challenges are now headed to the Michigan Supreme Court. For now, the Michigan 24% marijuana tax remains in effect, generating funds for roads while its legality is decided in court.
