HARRISBURG — The Pennsylvania House and Senate moved toward a showdown over competing spending and tax plans Monday, with the fate of suffering counties, schools and social services agencies hanging in the balance of a 5-month budget stalemate.

In bipartisan votes, the Senate overwhelmingly passed a $30.8 billion spending plan — which could come with a full-year tax increase of more than $1.2 billion — and legislation to cut costs and overhaul benefits in Pennsylvania’s two mammoth public-sector pension systems.

Gov. Tom Wolf, a Democrat, supports both bills, his office said. However, the fate of both was uncertain in the House.

A House vote today was possible on a competing $30.3 billion budget bill that contained hundreds of millions of fewer dollars for education and human services.

It emerged after the House Republican majority rebelled over the weekend, objecting to the size of the spending and tax increases in a deal their leadership negotiated with Wolf and Senate leaders.

Senate leaders said it was time to end the stalemate and defended their plan as the kind of compromise necessary to get Wolf’s signature.

“Eventually we are judged by our results. It’s nice to be for something, but if you never get anything passed or signed, what good are you?” Senate Majority Leader Jake Corman, R-Centre, told reporters after the vote.

If the House sends a different plan, Corman said, “hopefully it’s something that can get support in both chambers and get a signature by the governor.”

The 11th-hour standoff erupted over the weekend, after top lawmakers vowed to remain in the Capitol until they end the stalemate with Wolf. Many lawmakers were left wondering Monday how the impasse will end, considering the large differences between the House GOP and the plan supported by the Senate and Wolf.

The House GOP budget bill passed the Appropriations Committee in a party-line vote Monday. House Democrats said they had little time to get a look at the rushed House GOP budget bill and said Wolf opposes it.

“Sending this plan to the governor would be a total non-starter,” said Allegheny County Rep. Joe Markosek, the ranking Democrat on the Appropriations Committee.

Wolf has insisted on a tax increase to deliver a record boost in aid to public schools and narrow a long-term budget deficit. As a trade-off, he had agreed to sign legislation long-sought by Senate Republicans to scale back public pension benefits and by House Republicans to allow private businesses to sell wine or liquor outside the state-controlled system.
