Montana Dept. of Revenue Begins Medical Marijuana Provider Tax Process

The Montana Department of Revenue reminds medical marijuana providers to file their first Medical Marijuana Provider tax return and payment by October 15, 2017. The tax return and payment are for the quarter ending September 30, 2017.

Montana’s Medical Marijuana Act, or SB 333, was passed by the 2017 Legislature and creates a tax on the gross revenues of providers of medical marijuana products. The tax is 4% of gross revenues up through the period ending June 30, 2018, and 2% for subsequent years.

Medical marijuana providers should file their tax returns electronically on the department’s website at

The department is accepting any method of payment for this tax, including cash, however we highly recommend electronic or non-cash payment methods. Providers can pay online when they file their return, or send checks and money orders to:

Montana Department of Revenue

PO Box 6169

Helena, MT 59604-6169

Providers can also deliver a cash payment to a drop box in Helena. The department will not accept cash payments at any other locations. The drop box is located at the department’s downtown building, 340 N. Last Chance Gulch, Helena, MT 59601. The lobby is open Monday through Friday from 9 a.m. to 4 p.m., except on holidays.

Additional Steps When Paying by Cash

  1. All cash payments must be in a tamper-evident deposit bag. Enclose the cash in the bag before entering our lobby. The bag must be no larger than 11” x 13.” Do not overstuff the bag – it must fit in the drop box slot. Use more than one bag if your payment does not fit in one. You can buy bags online and office supply stores. 

2. Print a payment voucher from MyRevenue at

3. Include a copy of the voucher in each deposit bag.

4. Write the provider name and ID on each deposit bag.

5. To maintain accuracy, sort cash by denomination. The department will not accept any mutilated or contaminated currency. Exact amount is required. The department is not equipped to make change.
