Bonuses for Cost-Cutters Act of 2023 This bill temporarily expands the awards program for cost-saving identifications by federal employees of fraud, waste, or mismanagement to include identifications of surplus salaries and expenses funds. Savings resulting from such identifications shall generally be used for deficit reduction, but agencies may retain up to 10% of such savings for the purpose of paying cash awards to employees for making the identifications. An officer may not receive such award if the officer (1) serves in a position at level one of the Executive Schedule; (2) is the head of an agency; or (3) is a commissioner, board member, or other voting member of an independent establishment.
