Proposed Class Action - Colorado Marijuana Excise Tax
Colorado MED licensees may have a claim for refunds of overpaid excise tax — plus 10% annual interest, compounding from the date of first collection.
Years of inflated tax.
Find out if you may have a claim for a refund.
For years, Colorado's MED inflated the marijuana excise tax rate to as much as 17 times what the market actually paid. Their own data team admitted it in writing. The Governor's office reviewed the data and approved publication of the inflated rate anyway. If you held a Colorado MED license, you may have a claim for a refund - with 10% annual interest, going back to the date of first collection.

The case seeks refunds of excise tax allegedly overpaid under the unlawful methodology, going back to the date of first collection.
Mandated by Colorado Constitution Art. X, § 20(1) for unlawful tax collections, calculated from the date of first collection.
The lawsuit seeks to stop audit referrals and penalties premised on the alleged unlawful AMR.
The lawsuit asks the court to require a separate AMR for each statutory category and public quarterly transparency on transaction-level data.
Three claims being filed: TABOR violation · ultra vires conduct · procedural due process violation. Outcomes depend on court rulings; nothing on this page is a guarantee of recovery.
Are You Eligible?
Vertically integrated operators got hit hardest. They're required to use the published AMR for internal transfers, so every dollar of inflation lands directly on their tax bill - no retail buyer to absorb it.
The Smoking Gun
On March 8, 2025, MED's Data Analytics Manager admitted in writing that the Department was blending categories the regulation requires to be calculated separately - and that the inflation was roughly 17x the actual market rate. Nine days later, after review by the Department's Executive Director and the Governor's office, MED published the inflated rate anyway.
Add Your Name
If you held a Colorado MED license at any point during the affected period - even if you've since exited the market - you may have a claim. Counsel for the proposed class will review your information and reach out to confirm eligibility.
