Payroll Taxes and Other Payroll Deductions Payable
As a co-employer, we generally assume responsibility for the withholding and remittance of federal and state payroll taxes and other payroll deductions with respect to wages and salaries paid to our WSEEs. As of September 30, 2023 and December 31, 2022, payroll taxes and other payroll deductions payable were $518.1 million and $556.1 million, respectively. The balance at September 30, 2023 includes $149.3 million of funds we received in late September 2023 from the Internal Revenue Service for employee retention tax credits claimed by our PEO clients under the COVID relief programs, that were distributed to clients in early October 2023.
