Maryland did what legislatures are supposed to do: it found a way to make the wealthiest corporations in human history contribute to the public infrastructure on which their profits depend. On Aug. 14, the Maryland Tax Court handed those corporations a gift, striking down the state’s digital-advertising tax as unconstitutional and ruled it in violation of the federal Internet Tax Freedom Act. The tech giants who sued—Apple, Peacock TV, and Google—can now expect refunds of every penny they paid, plus interest, a combined exposure of roughly $535 million flowing back to some of the most cash-rich entities on the planet while Maryland schools, roads, and hospitals wait.
The law itself was modest by design. Passed in 2021, it levied a graduated surcharge on digital-advertising receipts: companies pulling in at least $100 million in global annual revenue paid 2.5 percent, scaling up to 10 percent for those exceeding $15 billion. That structure was a deliberate concession to progressive taxation—the bigger your global haul, the more you owe on the slice of advertising revenue you extract from Maryland’s digital audience. It was not subtle about its targets, nor did it need to be. The companies taxed could afford it many times over.
The court’s reasoning rested on three pillars, each more protective of corporate interests than the last. First, the Internet Tax Freedom Act: the court held that Congress intended to immunize all internet services from state taxation unless comparable non-digital services faced equivalent levies. Second, the dormant Commerce Clause: because the tax rate was pegged to global revenue rather than in-state activity alone, the court concluded that Maryland was “unquestionably” taxing activity outside its borders. Third, in the Peacock TV proceeding, the court found a First Amendment violation, reasoning that distinguishing digital from other advertising amounted to a content-based distinction on speech.
Read together, these holdings amount to a doctrine that the Constitution and a 1998 federal statute conspire to make it virtually impossible for a state to impose any meaningful levy on the digital economy’s advertising pipeline—a pipeline that routes billions of dollars of commerce through Maryland residents’ screens every day. The companies involved never disputed that they earn substantial revenue from Maryland audiences. Their argument was that the state had no right to calculate its tax using the only revenue figure that reflects the full scope of their digital-advertising operations: global revenue. The court agreed, and in doing so codified the principle that tech corporations’ worldwide earnings are a jurisdictional shield, not a measure of their market dominance.
Lawmakers in Illinois, Utah, and Washington should take notice—not as a warning, but as a challenge to draft better. Utah taxes digital advertising under a global-revenue threshold. Illinois separates digital from other forms of advertising in its tax code. Washington includes digital advertising in its sales-tax regime. Each will now face the same constitutional gauntlet Maryland’s law just ran. But the answer is not retreat. It is precision: drafting statutes that tie revenue calculations to verifiable in-state economic activity, that survive Commerce Clause scrutiny, and that do not hand courts an easy First Amendment off-ramp.
The most revealing detail in the Maryland saga is what lawmakers did in 2026. As the litigation wound toward its conclusion, the legislature passed a rule reducing the interest rate on refunds that courts might eventually order. Critics called it a vote of no-confidence in the state’s own law. It was something more practical: an attempt to limit the financial damage of a judicial decision that would force taxpayers to compensate corporations for the privilege of being taxed. The interest adjustment was the responsible move—tightening fiscal exposure while the legal questions remain unresolved.
Maryland has not indicated whether it will appeal. It should, and aggressively. The alternative is to return half a billion dollars to companies whose combined market capitalization exceeds the gross domestic product of most nations, and to confirm that the digital economy operates under a de facto tax exemption no other sector enjoys. Democrats across the country will keep pushing for digital-economy accountability. States tempted to follow Maryland’s lead should draft their laws with more care, yes—but they should not mistake a single court’s interpretation for a permanent constitutional barrier. The law was a first draft. The principle behind it— that the digital economy owes its fair share—remains as sound as ever.
