TECH GROUPS, CHAMBER CHALLENGE MARYLAND DIGITAL TAX: 

TECH GROUPS, CHAMBER CHALLENGE MARYLAND DIGITAL TAX: A trio of technology trade groups joined by the U.S. Chamber of Commerce sued in Maryland on Thursday to challenge a recently enacted tax on digital advertisers, POLITICO’s Bernie Becker reports. In a complaint filed in U.S. District Court of Northern Maryland, the Chamber, the Internet Association, NetChoice and the Computer & Communications Industry Association “called Maryland’s new tax ‘illegal in myriad ways,’ charging it runs afoul of both the Internet Tax Freedom Act,” a 1998 law that bars states from implementing discriminatory taxes on electronic commerce, and the Constitution’s Commerce Clause.”
