HARRISBURG, Pa. (AP) — The Pennsylvania state budget is due in two days. The finishing touches are being put on the $43 to $44 billion spending plan, but negotiations have hit a snag over education funding and it is unclear whether lawmakers and the governor will beat the clock before the state loses some of its spending authority in three days.

No main spending bill has been unveiled, and hundreds of pages of budget-related legislation remained under wraps on Tuesday. Closed-door talks were still going on as top Republican lawmakers remained tightlipped, even with rank-and-file Republicans in the House and Senate, saying they didn’t want to undermine their negotiating strategy.

“We’re having meetings today and I think that we’re getting to a good spot,” Senate Majority Leader Kim Ward, R-Westmoreland, said in brief comments in a Capitol hallway between meetings.

Work was unlikely to be done before the weekend and Wolf has generally stayed out of sight in the Capitol.

Without new budget legislation signed into law by Friday, the state will lose the authority to make some payments, although it could be weeks before any effect on services is felt.

Still, the approaching budget deadline has begun to revive memories of protracted, monthslong budget fights between Wolf and the Republican-controlled Legislature in 2015 and 2017 that inflicted lasting stress on counties, schools and social services agencies, and precipitated another credit downgrade.

“When you’re still talking three days before the deadline, that’s a stalemate,” said Rep. Frank Ryan, R-Lebanon.

The talks revolve around the amount of money Wolf is seeking for public schools, after he asked for almost $1.8 billion more for instruction, operations and special education, or about 21% more. Of that, $300 million was set aside for the 100 poorest public school districts and $200 million for special education.

Wolf’s budget secretary Greg Thall says a historic surplus warrants the historic investment in kids that Gov. Wolf is seeking.

“We have $18 billion in the bank we’re gonna have a $10 billion surplus and we’re squabbling over a billion dollars,” Thall said.

Republican state Senator Ryan Aument says they are committed to investing dollars into schools, but it is a question of how much and what they are committing themselves to in the years to come.

Thall would not discuss what sort of concessions Republican lawmakers were seeking from Wolf, saying only that “the list they’ve asked for is long and ridiculous.”

However, he said the state is awash in billions of dollars in surplus revenue and that lawmakers should act to help “people who are struggling in the economy.”

The budget is being negotiated against the backdrop of Wolf pursuing a number of policy goals unilaterally that Republicans broadly oppose, and Republicans say they have raised those matters in closed-door talks as they seek concessions.

Those include Wolf’s plan to toll up to nine interstate bridges, subject charter schools to stronger ethics, accounting and admissions standards and require fossil fuel-fired power plants to pay a price for every ton of carbon dioxide they emit.

Republican leaders are willing to send more money to public schools, but perhaps one-third to one-half of the amount Wolf requested. The state must be wary of overspending with an economic slowdown possibly on the way, they say.

Greasing the skids this year is a massive influx of tax receipts leaving the state’s bank accounts flush with — by some estimates — $12 billion in reserves and surpluses, boosted by inflation and an economy juiced with federal pandemic subsidies.

Despite the state’s brimming bank accounts, budget makers are not discussing a broad-based tax cut in sales or income as part of the budget.

Cutting corporate taxes, however, is a central part of budget talks, as is expanding the state’s property tax and rent rebate program, which is open to people 65 and over, widows and widowers 50 and over and disabled people 18 and over.

In a long-term stalemate, the state is legally bound to make debt payments, cover Medicaid costs, issue unemployment compensation payments, keep prisons open and meet biweekly payrolls, state officials said.

But Wolf’s administration could postpone payments to vendors, such as utilities, insurers, suppliers and landlords, and put off paying discretionary items, such as tax credits, grants and public school aid.
