HARRISBURG – The Pennsylvania Senate majority leader suggests a tax increase will likely be necessary to pass a state budget for the soon-to-start fiscal year. Senate Majority Leader Dominic Pileggi said Tuesday that it will be a challenge to pass a budget without the higher spending level that a tax increase would support. Lagging state tax collections and several other assumptions have torn a substantial hole in Gov. Tom Corbett’s proposed $29.4 billion budget plan. The governor’s office says new revenue will be necessary to support new money for public schools and human services aid. The new fiscal year starts July 1.
