HARRISBURG, Pa. (AP) — Republican lawmakers are advancing a $3 billion tax cut, their newly unveiled counterproposal to a budget proposal from Democratic Gov. Josh Shapiro as each side offers a competing vision for how to use a massive cash surplus. The legislation cutting taxes on income and electric service passed the Republican-controlled Senate on a 36-14 vote Tuesday. Republicans said it would be the largest tax cut in the state’s history. In the coming weeks, budget negotiations could revolve around Shapiro’s bid to boost spending by $3 billion, versus the Republican counterproposal to cut taxes by $3 billion. Democrats warn that the Senate GOP’s tax bill won’t pass in the Democratic-controlled House.
