Michigan’s 24% wholesale tax on marijuana generated tens of millions less than expected in its first four months, according to a new report from the Michigan Treasury Department.
The tax took effect Jan. 1 and was projected to generate $420 million a year to pay for road and infrastructure improvements. A state treasury report shows the new tax brought in only about $34 million in the first four months of 2026, $70 million less than the $105 million expected.
