HARRISBURG, Pa.—In a major victory for Pennsylvania’s arts community, a proposal to extend the state sales tax to cultural performances and venues, including museums, has died in the Legislature.

Cultural advocates statewide had strongly opposed the plan, first announced last month and intended to generate an additional $100 million to $120 million in revenue. The plan was to create a special fund for cultural institutions and the arts, with the fund getting the bulk of the ticket-tax revenue. That revenue would have been used to support institutions previously subsidized by the general fund, such as museums, theaters, and zoos. The tax proposal was defeated when the Pennsylvania House of Representatives passed a revenue bill last week. Still, state support for the arts has been greatly cut back and even eliminated in the case of historical museums and sites.
