- Maryland’s Tax Court ruled the state’s first-in-the-nation digital advertising gross receipts tax unconstitutional, ordering refunds to Apple, Google, and Peacock TV (Comcast).
- The tax, enacted in 2021, imposed rates from 2.5% to 10% on annual digital ad revenue exceeding $1 million, targeting companies with global revenues above $100 million.
- The court found the tax violated the federal Internet Tax Freedom Act and the U.S. Constitution’s Commerce Clause, which bars discrimination against interstate commerce.
- Refunds are due to the three named plaintiffs, but the ruling could open the door for other affected companies to seek similar relief, potentially costing Maryland hundreds of millions in annual revenue.
- The decision is a setback for state-level digital taxation efforts, though Maryland officials may appeal to the state’s highest court.
Court Strikes Down Landmark Digital Ad Tax
The tax, first enacted in 2021 over a gubernatorial veto, imposed a graduated rate structure on annual digital advertising revenue exceeding $1 million. Companies with global revenues above $100 million were subject to rates ranging from 2.5% for those earning up to $5 million in Maryland, escalating to 10% for those with over $15 billion in global revenue. The plaintiffs argued that the tax was discriminatory because it applied only to digital advertising, not traditional print, radio, or broadcast advertising, and that it unfairly targeted out-of-state corporations.
Legal Basis: Internet Tax Freedom Act and Commerce Clause
In its ruling, the Maryland Tax Court agreed with the plaintiffs on two primary grounds. First, it held that the tax violated the federal Internet Tax Freedom Act (ITFA), which prohibits discriminatory taxes on electronic commerce. The court reasoned that singling out digital advertising for a unique tax burden, while exempting comparable offline advertising, constituted exactly the kind of discrimination the ITFA was designed to prevent. Second, the court found the tax ran afoul of the Commerce Clause of the U.S. Constitution, which prohibits states from imposing taxes that unduly burden or discriminate against interstate commerce.
The court’s reasoning emphasized that the tax’s structure effectively created a “digital-only” levy, a distinction that could not withstand constitutional scrutiny. “The tax is not a general business tax but a targeted imposition on a specific medium of commerce,” the ruling stated, according to court documents reviewed by financial analysts. The decision orders the Maryland Comptroller’s Office to refund all amounts paid by the three plaintiffs, with interest, though the exact dollar figures were not immediately disclosed in the public summary of the ruling.
Broader Implications for State Digital Taxes
This ruling carries implications well beyond Maryland’s borders. Over the past several years, at least a dozen other states, including Connecticut, Massachusetts, and New York, have considered or proposed similar digital advertising taxes as a way to capture revenue from tech giants that have historically paid little in state corporate taxes. The Maryland decision provides a legal precedent that could be cited by opponents of such measures, potentially chilling legislative efforts in other jurisdictions. However, legal experts note that the ruling is from an administrative tax court, not a state appellate court, and its precedential value may be limited if appealed.
For the companies involved, the refunds are a modest financial win relative to their massive balance sheets, but the strategic victory is more significant. Apple, Google, and Peacock TV (a unit of Comcast) collectively spent millions on legal fees to challenge the tax, viewing it as an existential threat to their advertising business models. The ruling also removes a compliance burden that required these firms to track and allocate digital ad revenue by state, a complex process given the nature of programmatic advertising auctions.
What Happens Next: Appeal Likely
Maryland officials, including Comptroller Brooke Lierman, have not yet publicly commented on whether they will appeal the Tax Court’s decision to the Maryland Court of Special Appeals. Given the revenue at stake—the tax generated approximately $200 million in its first two years of collection, according to state budget documents—an appeal is widely expected. If the decision stands, Maryland would need to find alternative funding sources for the Kirwan Commission education reforms, which were a primary driver for the tax’s enactment.
For investors, the immediate market reaction was muted, as the ruling was largely anticipated by legal observers. However, the decision removes a near-term earnings risk for companies with significant digital advertising exposure. The broader takeaway is that state-level attempts to tax digital services remain legally fragile, and any future proposals will likely need to be structured more carefully to avoid the constitutional pitfalls identified in this case. As of today, August 15, 2026, no appeal has been filed, and the refund process for the named plaintiffs is expected to begin within the coming weeks.
