Pennsylvania lawmakers opted for a budget Friday that saves most of the state’s $10 billion in tax surplus and federal stimulus as they brace for an unprecedented fiscal cliff when the good fortune “dries up” come 2024.

The $40.8 billion spending plan socks away $2.5 billion in unexpected sales tax revenue into the state’s nearly depleted Rainy Day Fund and holds back two-thirds of the $7.3 billion in stimulus received from the American Rescue Plan for future deficits, leaving just enough for line item increases to public education, transportation projects and nursing homes, among other priorities.
