Today, McDermott Will & Emery filed suit in Maryland federal court on behalf of a number of leading trade associations against Maryland Comptroller Peter Franchot, challenging the state’s recently enacted 10% gross receipts “tax” applicable to digital advertising revenue. The plaintiffs in the suit are the US Chamber of Commerce, the Internet Association, NetChoice and the Computer and Communications Industry Association. The suit asks that the court invalidate Maryland’s punitive imposition as violating several provisions of the US Constitution and the Internet Tax Freedom Act.

A file-stamped copy of the complaint is available below:



The complaint alleges that Maryland’s focus on internet advertising services (the tax does not apply to traditional advertising) discriminates against the internet, violating the Internet Tax Freedom Act. Next, because Maryland’s new law burdens and penalizes conduct occurring outside Maryland, it violates the Commerce and Due Process Clauses of the US Constitution. The complaint alleges that the characteristics of the imposition and the circumstances surrounding its enactment demonstrate a clear purpose and intent to punish out-of-state digital advertising companies for their extraterritorial activities.

The case is Civil No. 21-cv-410 (D. Md., filed February 18, 2021). Michael B. Kimberly, Paul W. Hughes, Stephen P. Kranz and Sarah P. Hogarth of McDermott, Will & Emery’s Washington, DC, office represent the plaintiffs.

Practice Note: The filing of this suit sends a signal to other states, like New York, Connecticut and Montana, where similar proposals are under consideration. Policymakers in those other states should recognize that following Maryland’s lead will only lead to the courthouse.
