Michigan’s 24% Cannabis Tax Heads to Fast Track—Industry Bleeding Cash as Court Battle Escalates

In an unusual move signaling urgency, the justices directed the Michigan Court of Appeals to take up the case on an expedited track.

For now, however, the tax remains fully in effect.

Pressure Builds Across Michigan’s Cannabis Industry

The lawsuit, led by the Michigan Cannabis Industry Association (MiCIA), argues the tax was imposed in a way that violated what voters approved when they legalized recreational marijuana.

“This is exactly what we’ve been asking for,” said MiCIA spokesperson Rose Tantraphol. “The clock is ticking for cannabis businesses that are struggling all across the state.”

At the center of the fight is a 24% wholesale tax tucked inside the Comprehensive Road Funding Tax Act—a sweeping road funding package passed during a late-night legislative session last fall.

What Is the 24% Cannabis Tax Fight About?

The core dispute comes down to two big questions:

• Did lawmakers overstep voters?
  Cannabis legalization was approved by voters—but the Legislature later added a 24% wholesale tax through separate legislation.
• Is this really a “sales tax” in disguise?
  Michigan caps sales tax at 6%. Plaintiffs argue this 24% levy effectively acts like a hidden sales tax—far above the legal limit.
• Why it matters:
  If the courts agree, the tax could be struck down—and potentially trigger refunds or major policy changes.

Two Legal Fronts, One Big Risk

MiCIA’s challenge has evolved into a two-front legal battle:

• Original lawsuit: Claims lawmakers violated the voter-approved cannabis framework.
• New lawsuit (March): Argues the tax is unconstitutional because it exceeds the state’s 6% sales tax cap.

The case now includes growers, retailers, and even a cannabis consumer—broadening both the legal argument and potential impact.

Courts So Far: No Relief

In December, Sima Patel denied a request to block the tax before it took effect.

That ruling kept the tax in place—and despite the Supreme Court stepping in, nothing changes immediately for businesses.

What the 24% Tax Means in Dollars

Here’s where this gets painful—and why the industry is pushing so hard.

Example: A typical cannabis supply chain transaction

• Grower sells product to retailer: $1,000 wholesale value
• New 24% tax applied: +$240
• Total cost to retailer: $1,240

Now layer on reality:

• Retailers already face price compression (falling cannabis prices statewide)
• Margins are often razor thin (10–20%)
• That extra $240 often gets:
  • Passed to consumers → higher prices
  • Or absorbed → lower profits, layoffs, closures

Scale that up:

• A mid-size operator moving $1 million/month wholesale
• Additional tax burden: $240,000 per month
• Annual hit: nearly $3 million

That’s not theoretical—that’s survival-level pressure.

Legislative Backup Plan in Play

While the courts move, industry advocates are also pushing lawmakers.

State Sen. Jonathan Lindsey (R-Coldwater) has introduced Senate Bill 810, which would repeal the road funding law that created the tax.

For now, the bill remains stuck in committee.

What Happens Next

The Supreme Court didn’t decide the case—but it just sped up the timeline.

That matters because:

• Businesses are already feeling the financial strain
• The longer the tax stays in place, the deeper the damage
• A ruling could come faster than expected—and reshape the industry overnight

Michigan’s cannabis industry is now in a race against the clock:

• If the tax is struck down: Operators could get relief—and possibly refunds
• If it stands: The state locks in one of the highest effective cannabis tax burdens in the country

Either way, this isn’t just a legal fight anymore.

It’s a battle over whether a fast-growing Michigan industry can stay profitable—or gets squeezed into consolidation.
