Medical Cannabis Federal Taxation Seminar

Are you thinking about applying for a medical marijuana dispensary or cultivation facility license in Arkansas?

The IRS 280E statute is a major hurdle for cannabis businesses when tax time comes around because it states that only expenses that are considered Cost of Goods Sold (COGS) are able to be deducted for federal income tax purposes. This can lead to much higher federal income tax burdens when compared to normal, non-cannabis businesses.

Sarah A. Vestal, PhD, a revenue agent with the Internal Revenue Service with a specialty in cannabis taxation, will educate prospective dispensary and cultivation facility applicants on the ins and outs of IRS code 280E and will provide examples of how the IRS actually conducts audits of cannabis businesses. Robert J. Clock, CPA, an Arkansas accountant on the board of the ACIA, will talk about the implications of 280E from the tax accounting perspective.

A question and answer segment will follow their presentation.

Please join us Tuesday, September 5th from 6pm to 7pm.

RSVP at the Facebook event page or by emailing Info@ARcannabis.org.
