Trulieve Cannabis Corp. has filed amended federal tax returns with refund claims for several of its business entities for 2019, 2020, and 2021.

In total, Trulieve is claiming a refund of $143 million from taxes paid that it believes it does not owe, although the company noted there is no guarantee of receipt. 

Trulieve said it filed the refund based on legal interpretations that challenge its tax liability under Section 280E of the Internal Revenue Code, which prohibits businesses that sell Schedule I or Schedule II substances from deducting ordinary business expenses. The company did not elaborate on the legal interpretations in a news release.

Some U.S. states have decoupled its tax rules from Section 280E of the Internal Revenue Code, allowing legal cannabis companies to deduct certain business expenses. They include  Arkansas, California, Colorado, Hawaii, Louisiana, Maryland, Massachusetts, Maine, Michigan, Minnesota, Mississippi, Missouri, Montana, New Mexico, New York, Oregon, Texas, Vermont and Virginia, accounting and consulting firm Armanino reported.
