The ruling found the levy violated the federal Internet Tax Freedom Act by targeting only electronic commerce.
Maryland's tax court struck down the state's digital advertising tax on Friday, ruling the levy violated the federal Internet Tax Freedom Act by applying only to electronic commerce. The tax, the first of its kind in the nation, was invalidated in a group of decisions issued by the court.
The court found that Maryland's tax structure improperly targeted digital advertising platforms while exempting traditional media and other forms of commerce. The ruling centered on the interpretation of the Internet Tax Freedom Act, which restricts states from imposing discriminatory taxes on electronic transactions.
The Maryland digital advertising tax had been designed to generate revenue from large technology companies operating advertising platforms in the state. The tax court's decision removes the levy from the state's tax code and sets a legal precedent that may affect similar efforts in other jurisdictions.
The ruling came in a consolidated set of cases heard by Maryland's tax court. The decisions were issued Friday and address the constitutional and statutory questions raised by taxpayers challenging the tax.
The Internet Tax Freedom Act, which the court cited as the basis for its ruling, prohibits states from imposing taxes that discriminate against electronic commerce. The Maryland tax court determined that by singling out digital advertising while leaving other advertising channels untaxed, the state had crossed that legal threshold.
The decision eliminates a revenue stream Maryland had projected from technology companies with substantial digital advertising operations. The tax had been structured to apply based on the volume of digital advertising revenue generated within the state.
The Deployment Angle

Family offices holding stakes in digital media platforms, ad-tech companies, or e-commerce businesses should reassess state tax exposure in light of Maryland's failed levy. The ruling establishes that digital-only taxes face federal preemption risk under the Internet Tax Freedom Act, which narrows the range of state-level regulatory costs to underwrite when evaluating tech-sector investments.
For families considering direct ownership of digital advertising businesses or platform equity, the decision reduces one category of jurisdiction-specific tax risk. It does not, however, eliminate the broader trend of state revenue departments targeting technology companies through sales tax nexus rules and apportionment formula adjustments. Those remain live underwriting concerns.
Families deploying capital into programmatic joint ventures with sponsors active in digital media should pressure-test whether the sponsor's tax structuring accounts for state-level discrimination claims. The Maryland precedent suggests that carve-outs for electronic commerce create litigation risk, which translates to reserve requirements and cash-flow volatility for operating companies.
Avoid platform investments in jurisdictions that have proposed Maryland-style digital advertising taxes but have not yet faced judicial review. The legal cost of challenging discriminatory levies, even when successful, erodes returns. Better to direct capital toward sponsors and geographies with settled tax frameworks or toward asset classes where state tax treatment is uniform across delivery channels.
