In the 1960s Washington added a retail sales tax that would be charged at any business that offers customers the "opportunity" to dance. According to ABC News, many Washington businesses complain of arbitrary enforcement of the statute. The state legislature is considering a repeal.
Proponents of the repeal say enforcement targets medium-sized venues or taverns, and not places like sports stadiums that often host concerts where people dance. Recently, Century Ballroom in Seattle and was hit with $250,000 bill on back taxes for not adhering to the law.
