Dear Licensees and Taxpayers,

As you may be aware, recent legislation has resulted in changes to the frequency of Average Market Rate (AMR) re-calculation, to how the Retail Marijuana Excise tax on Retail Marijuana is calculated, to the state sales tax exemptions and to the Retail Marijuana Sales tax levied on Retail Marijuana at the point of sale. In addition, the new AMR rates effective July 1, 2017 have been published. Please see the attached AMR fact sheet which is effective for the quarter beginning July 1, 2017, and the attached fact sheets with a brief synopsis of the upcoming changes to taxation. As always, we encourage you and your representatives to stay abreast of all tax and regulatory requirements to remain in compliance.

Here are the highlights of changes. Please read the attached fact sheets for more details about how these changes affect you. You can also find FYI publications about these taxes on the Taxation Division’s website,
