The Michigan Department of Treasury has officially published the assumed wholesale-to-retail markup rate for the wholesale marijuana tax period covering April 1 to June 30, 2026. Licensed cannabis businesses now have clear guidance on the 50% markup used to calculate the state excise tax on marijuana products.
This quarterly update provides essential clarity for retailers, processors, and growers across Michigan. The assumed markup percentage is a key component in determining the taxable wholesale price of cannabis products, ensuring consistent and accurate tax calculations during the second quarter of 2026.
For licensed operators, the Michigan Wholesale Marijuana Tax Guidance is critical for compliance and cash-flow planning. The Treasury’s announcement helps businesses avoid under- or over-reporting of tax liabilities and supports smooth operations as the industry continues to mature under Michigan’s regulated cannabis framework.
Businesses are encouraged to review the full guidance and update their accounting systems accordingly before the April 1 effective date.
