On January 8, SB 2 was introduced to establish a new digital advertising gross revenue tax of up to 10% on “annual gross revenues of a person derived from digital advertising services in the state.” This uncharted new tax would make Maryland the first state or locality in the United States to impose a targeted tax on the gross revenue of digital advertising services.

The bill defines “in the state” as appearing on the user’s device located in the state (determined based on either the user’s IP address or reasonable knowledge). “Digital advertising services” is defined as “advertisement services on a digital interface, including advertisements in the form of banner advertising, search engine advertising, interstitial advertising, and other comparable advertising services.” The definition uses the word “includes” rather than “means,” enabling the definition to be read even more broadly. “Digital interface” is defined as “any type of software, including a website, part of a website, or application, that a user is able to access.”

The tax applies at a sliding scale:

• 2.5% for person with global annual gross revenues of $100 million or more

• 5% for person with global annual gross revenues of $1 billion or more

• 7.5% for person with global annual gross revenues of $5 billion or more

• 10% for person with global annual gross revenues of $15 billion or more

The bill would require quarterly estimated tax payments and an annual return and provides that willful failure to file a digital advertising gross revenues tax return is a misdemeanor subject to a $5,000 fine and 5 years’ imprisonment.

The bill is co-sponsored by Senator Thomas Miller (D), the outgoing Senate President, and Senator William Ferguson (D), the incoming Senate President. Maryland legislative leaders have been hinting at new taxes on the digital economy, digital downloads, and streaming subscriptions as they decide how to fund a proposed $825 million per year education spending increase. Governor Hogan (R) opposes the education spending increase as too expensive, amounting to a $6,000 per family tax increase, and in response Democrats last week ruled out raising income, sales, or property tax rates. We therefore may see additional digital taxation bills aside from this one.

Because Maryland would tax digital advertising but not tax non-digital advertising, the tax is a “discriminatory tax” prohibited by the Permanent Internet Tax Freedom Act (PITFA). The use of an arbitrary threshold of global annual gross revenues, while perhaps politically popular, serves to tax larger global advertising service providers at a higher tax rate than their domestic counterparts, in violation of the Commerce Clause of the US Constitution. The proposal also raises serious First Amendment (singling out digital commercial speech for a punitive tax) and Equal Protection (lack of rational basis for punitive tax on digital advertising) issues.
