In a landmark decision, Maryland’s pioneering digital advertising tax has been invalidated by the state’s tax court, which has also directed the reimbursement of funds collected from major technology companies. This ruling has garnered attention nationwide as other states contemplate similar fiscal measures.
The Maryland Tax Court determined that the digital ad tax contravenes the federal Internet Tax Freedom Act, the First Amendment, and the commerce and due process clauses of the U.S. Constitution. This decision is a significant development for states that have been monitoring Maryland’s approach, which was projected to generate approximately $250 million annually to support an extensive K-12 education initiative.
As part of the court’s ruling, companies like Apple, Google, and Peacock TV can expect refunds on taxes paid under the now-overturned law. The tax targeted revenues from digital ads displayed within the state, imposing a 2.5% tax on firms earning over $100 million globally, with the rate escalating to 10% for those with annual global gross revenues of $15 billion or more.
Proponents of the legislation argued for the necessity of modernizing Maryland’s tax system to adapt to evolving advertising strategies. However, legal challenges from Big Tech entities, such as Meta and Amazon, were swift, arguing the law unfairly targeted their industry.
Previously, the 4th U.S. Circuit Court of Appeals found a portion of the law unconstitutional for restricting companies from informing customers about the tax, a violation of free speech, according to Judge Julius Richardson.
Maryland’s legislative leaders, Senate President Bill Ferguson and House Speaker Joseline Pena-Melnyk, have expressed their disagreement with the court’s decision, anticipating further legal proceedings. They emphasized their commitment to ensuring the state’s tax framework aligns with the contemporary economy.
“We remain committed to ensuring that Maryland’s tax system is fair, sustainable, and reflects today’s economy,” they stated. “We will continue working with the Attorney General and Comptroller as this matter proceeds through the courts.”
The court highlighted that regulating interstate commerce falls under the jurisdiction of Congress, not state legislatures. It criticized the tax’s reliance on global revenue metrics rather than local advertising income.
The federal Internet Tax Freedom Act, which prohibits taxes on e-commerce if similar offline services remain untaxed, played a crucial role in the court’s decision. The court noted that digital advertising is not sufficiently distinct from traditional advertising forms like print or billboard ads, thereby extending the tax exemption to digital ads.
