A key component in promoting the highest degree of voluntary compliance on the part of taxpayers is helping them understand and meet their tax responsibilities while also enforcing the law with integrity and fairness to all. This article provides general guidance including frequently asked questions for taxpayers in the marijuana industry.

The page contains sections on:

The page ends with a section titled “More Information” which begins with a link to a frequently asked questions page for the marijuana industry.[2]

The FAQ has the following questions on the page:
