Roughly 70% to 80% of eligible households claimed the state’s $250-per-child tax rebate before the application period closed Sunday, Gov. Ned Lamont’s office reported Monday. A total of 238,668 low- and middle-income households claimed the benefit on behalf of 369,883 children. That means $92.5 million or 74% of the $125 million that legislators appropriated for the program would be distributed.
