The CT Community Nonprofit Alliance asked Thursday for a share of projected future budget surpluses — more than $460 million over the next five years — to mitigate more than a decade of under-funding.

Despite predictions that Connecticut’s rainy day fund could continue to grow through 2024, the nonprofits’ big ask puts the sector on a collision course with Gov. Ned Lamont and many legislators over the state spending cap.

“Through more than a decade of tough budgets, while the need for services has only increased — nonprofits have had their budgets frozen or reduced,” said Gian-Carl Casa, president and CEO of the alliance. “Today we’re asking that the governor and the legislature provide us with the means to continue to help half a million people across the state.”
