Maryland Court Strikes Down US Digital Ad Tax in Win for Big Tech

Key Facts

1A Maryland tax court invalidated the state's digital advertising tax and ordered refunds of collected payments.

2The tax targeted companies with over $100 million in global revenue at rates between 2.5% and 10%.

In a move reflecting the growing legal challenges to local tax legislation targeting the tech sector, a Maryland tax court has struck down the first digital advertising tax in the United States. According to reports, the court invalidated the state's tax on digital ad revenues and ordered the refund of collected payments. The tax targeted companies with global revenues exceeding $100 million at rates ranging from 2.5% to 10%, with the court ruling that the measure violated the federal Internet Tax Freedom Act and the U.S. Constitution.

This ruling alleviates potential financial pressure on tech giants such as Google and Apple, which faced tax liabilities estimated in the hundreds of millions. Per market data, these instruments closed at varying levels on August 18, 2026, with AAPL at $310.565 and GOOGL at $343.41501. Peer performance remained relatively stable according to market data, with META closing at $550.0846 and MSFT at $481.65 on the same date.

Investors are now watching whether this ruling sets a precedent that discourages other U.S. states from implementing similar digital advertising taxes. At the close of August 18, 2026, GOOGL was trading near its daily high of $344.14, while AAPL moved within a range of $305.74 to $311.49. With no immediate related catalysts in the upcoming economic calendar, market focus remains on the potential for state authorities to appeal the decision.
