Comcast Lawsuit Argues New Washington Tax on Advertising Is Illegal
Comcast contends the law discriminates against internet ads by taxing them while exempting traditional media, potentially reducing state tax revenue by $475 million over four years, officials said.
- On September 9, Comcast initiated legal action in Thurston County to challenge Washington state's SB 5814, which will start imposing taxes on advertising services beginning October 1.
- The law, approved by the state legislature in April and enacted with the governor’s signature the following month, expands business taxes to help finance a $9 billion budget package.
- Comcast argues the law disproportionately taxes internet advertising while exempting most offline ads, violating the federal Internet Tax Freedom Act's ban on discriminatory taxes.
- Mikhail Carpenter stated striking the advertising tax could reduce revenue by roughly $475 million over four fiscal years, and Comcast warned the tax harms businesses, consumers, and the economy.
- If Comcast wins, it may prompt significant changes to the state budget and open the door to contesting comparable digital service taxes in other states.
