Michigan Cannabis Sales Tax in 2026

The 3 Taxes You Owe, Who Pays, and Every Deadline

Cannabis operators are managing three separate Michigan Cannabis Sales Taxes in 2026:

• A 24% wholesale excise tax on certain adult-use cannabis sales and transfers

• A 10% retail excise tax on adult-use retail sales

• A 6% Michigan sales tax on taxable retail purchases

These taxes apply at different points in the supply chain, involve different responsible parties, and require different records. The goal is direct: separate each tax obligation, connect every transaction to supporting documentation, and meet every filing deadline.

This guide explains the 2026 Michigan cannabis tax structure, including the new wholesale tax, transition-year relief, and the compliance systems you need to avoid preventable errors.

The three Michigan Cannabis Sales Taxes in 2026

Tax	Rate	Who is legally responsible?	When it applies
Wholesale Marijuana Tax	24%	The wholesaler or other entity making the first taxable transfer to a retailer	Wholesale sale, qualifying transfer, or retail-ready packaging beginning January 1, 2026
Marijuana Retailers Excise Tax	10%	The adult-use retailer	Retail purchase by a customer
Michigan sales tax	6%	The retailer collecting tax at the point of sale	Non-exempt retail sale of tangible personal property

The 24% wholesale tax does not replace the existing retail taxes. It applies upstream, while the 10% excise tax and 6% sales tax apply at retail.

Review the Michigan Department of Treasury’s official wholesale marijuana tax guidance and MRE tax information. Then build your reporting workflow around the correct tax. Separate the tax streams.

1. The new 24% wholesale marijuana tax

The wholesale tax took effect January 1, 2026, under the Comprehensive Road Funding Tax Act. Revenue goes to Michigan roads and bridges, including the neighborhood road fund and a comprehensive road funding fund.

Who owes the 24% wholesale tax?

The tax is legally imposed on the wholesaler, the marijuana establishment making the first sale or transfer of adult-use cannabis to a retail licensee.

It applies to:

• The first sale or transfer from a grower, processor, or other marijuana establishment to a retailer

• Cannabis cultivated and processed by a retailer for its own retail sale, including qualifying microbusiness activity

• Transfers from a medical provisioning center to an adult-use retailer

• Transfers from medical inventory to adult-use inventory by a dual licensee

• Retail-ready packaging by a qualifying seed-to-sale business

The wholesaler remains responsible for calculating, reporting, and remitting the tax even if it passes the tax through to the retailer on an invoice. An unpaid customer invoice does not automatically eliminate the wholesaler’s liability.

Identify the legally responsible entity for every taxable transfer.

Six wholesale tax traps Michigan operators must avoid

1. Treating the tax as the retailer’s obligation

The retailer may ultimately bear the economic cost if the wholesaler passes the tax through. However, the wholesaler is legally responsible for remitting the tax to Treasury.

Your invoice should clearly identify the product price, applicable charges, tax treatment, and transaction date. Document responsibility and pass-through terms.

2. Using a processor license to avoid tax

A company holding both processor and retailer licenses cannot automatically avoid the wholesale tax by purchasing retail-ready products under its processor license.

If the product will not undergo further processing, rebranding, or another legitimate transformation, sell it under the retailer license and treat it as taxable.

Match the license capacity to the actual transaction.

3. Missing medical-to-adult-use transfers

Wholesale sales of medical cannabis generally are not subject to the 24% tax. However, a transfer from medical inventory to adult-use inventory by a dual licensee is taxable.

Daily transfers or transfers made concurrently with individual retail sales do not avoid the tax. You must also track these transfers in METRC.

Reconcile medical and adult-use inventory movement.

4. Using the wrong price for related-party transactions

For unrelated parties, the tax is generally based on the actual price paid by the retailer.

For related parties, or a business growing and selling its own product, Treasury uses a quarterly average wholesale price list. That price may differ from your internal transfer price.

Check the current quarterly price list before calculating liability.

5. Excluding shipping and other invoice charges

For non-affiliated transactions, the taxable wholesale price includes applicable taxes, fees, shipping, handling, and other charges reflected in the invoice, bill of sale, purchase order, or related sales document.

Some bona fide services may be excluded when they are:

• Unrelated to acquiring the cannabis

• Separately stated

• Commercially reasonable

• Supported by a current contract or service agreement

• Not used to artificially reduce the cannabis price

• 
  

Review every invoice line before filing.

6. Misallocating mixed inventory

If a processor mixes inventory purchased before and after January 1, 2026, the processor does not receive a partial exemption when making a taxable sale to a retailer.

A sale to a retailer on or after January 1, 2026, is fully taxable on the entire sale price. No allocation is based on when the processor originally purchased the inventory.

A limited transition example exists: if a retailer purchased cannabis from a wholesaler on December 30, 2025, and resold it to another retailer on January 4, 2026, the January transaction is not taxable because the first sale to a retail licensee occurred before the effective date.

Track first taxable transfer dates, not just inventory purchase dates.

How the 24% wholesale Michigan Cannabis Sales Tax is calculated

Unrelated parties

For non-affiliated parties, the starting point is generally:

Actual price paid by the retailer × 24%

The taxable amount may include qualifying charges reflected in transaction documents. Prohibited discounts, volume discounts, rebates, or exclusivity-related reductions may not reduce the taxable wholesale price.

Related parties and self-supply operations

For affiliated businesses and seed-to-sale retailers, use Treasury’s quarterly average wholesale price.

The calculation generally requires you to:

• Identify the product category

• Confirm the applicable unit of measurement

• Use the average wholesale price for the quarter of the taxable event

• Multiply the taxable quantity by that price

• Apply the 24% tax rate

• Retain records supporting the category, quantity, date, and ownership relationship

• 
  

The taxable event occurs when ownership transfers to the retailer according to the contract or standard business practice. For seed-to-sale operations, the event occurs when the product is packaged as a final retail-ready unit.

Reconcile price, quantity, ownership, and date.

2026 Michigan cannabis tax deadlines

24% wholesale tax transition-year calendar

For 2026, Treasury requires good-faith quarterly payments:

• April 20, 2026: Q1 activity

• July 20, 2026: Q2 activity

• October 20, 2026: Q3 activity

• January 20, 2027: Full 2026 quarterly returns, remaining Q1–Q3 balance, and the full Q4 amount

  
  

Treasury will waive penalties and interest for the first three quarters of 2026 if you:

• Pay at least 75% of the final tax owed for each quarter by the applicable quarterly deadline

• File all required 2026 returns

• Pay the remaining balance, including the full Q4 liability, by January 20, 2027

Beginning in 2027, quarterly returns and full payment will be due each quarter. The good-faith partial-payment transition approach will no longer apply.

Calculate quarterly liability before each payment date.

10% Marijuana Retailers Excise Tax

The 10% MRE tax applies to adult-use retail sales and is filed quarterly on the Marihuana Retailers Excise Tax Quarterly Return, Form 5676.

For 2026 activity, the standard deadlines are:

• April 20, 2026: Q1

• July 20, 2026: Q2

• October 20, 2026: Q3

• January 20, 2027: Q4

  
  

The 10% tax supports distributions to municipalities and counties based on the number of licensed retail stores. In 2026, those distributions totaled approximately $93.7 million, averaging about $54,017 per licensed store.

File the MRE return separately from your sales tax return.

6% Michigan sales tax

The 6% state sales tax applies to non-exempt retail sales of tangible personal property, including adult-use cannabis sales.

Your filing frequency, monthly, quarterly, or annual, is assigned by Treasury. Generally:

• Monthly returns and payments are due by the 20th of the following month

• Quarterly returns and payments are due by the 20th of the month following the quarter

• The annual 2026 sales tax return is due February 28, 2027

  
  

For a quarterly filer, the 2026 schedule is:

• April 20, 2026: Q1

• July 20, 2026: Q2

• October 20, 2026: Q3

• January 20, 2027: Q4

Confirm your assigned filing frequency and current forms through the Michigan Treasury sales and use tax page.

Why this is a METRC and documentation problem

Michigan cannabis tax compliance is not only a tax-preparation issue. It is also an operational systems issue.

Your records should connect:

• METRC inventory movements

• Package creation and retail-ready dates

• Medical-to-adult-use transfers

• Wholesale invoices and purchase orders

• Shipping and handling charges

• Related-party ownership information

• Product categories and units of measure

• Contract terms controlling when ownership transfers

• Returns, credits, destroyed product, and chargebacks

• Quarterly tax calculations and payments

A disconnected process creates measurable risks: duplicate taxation, missed taxable transfers, incorrect pricing, unsupported deductions, and late filings.

Social Equity Solutions helps Michigan operators build documented systems through Michigan cannabis compliance consulting, METRC setup and operational support, compliance binders, standard operating procedures, and ongoing tracking workflows.

The goal is not to create more paperwork. The goal is to create a verified, trackable record that your operator, compliance team, and tax professional can use together.

Build the reconciliation system before the deadline arrives.

How to prepare now

Use this process for each filing cycle:

• Identify every taxable retail sale and wholesale transfer

• Separate adult-use and medical inventory

• Confirm whether the parties are affiliated

• Verify the applicable Treasury average wholesale price

• Reconcile invoices to METRC records

• Review shipping, handling, discounts, and service charges

• Calculate each tax separately

• Have a qualified tax professional review the return

• Submit payment and retain confirmation

• Store the supporting records in your compliance binder

Start the quarterly close early.

Frequently Asked Questions

Does the 24% wholesale tax replace the 10% retail excise tax?

No. The 24% wholesale tax applies upstream to qualifying wholesale sales and transfers. The 10% MRE tax and 6% sales tax apply at the retail transaction.

Does the retailer pay the 24% wholesale tax?

The wholesaler is legally responsible for calculating and remitting the tax. A wholesaler may pass the cost through to the retailer, but that does not transfer the wholesaler’s legal filing responsibility.

Is medical cannabis subject to the 24% wholesale tax?

Generally, no. The exception is a transfer from medical inventory to adult-use inventory by a dual licensee. That transfer is taxable and must be tracked in METRC.

Are processor-to-processor sales taxable?

A processor-to-processor bulk distillate sale generally is not subject to the wholesale tax because it is not the first sale or transfer to a retail-licensed entity.

What happens if inventory purchased before 2026 is mixed with post-2026 inventory?

A processor’s sale to a retailer on or after January 1, 2026, is fully taxable on the entire sale price. The processor does not allocate the sale based on when the inventory was purchased.
