An additional FICA tax of 0.9 percent will be imposed for employees whose wages are over $ 250,000 (if employee is married and files a joint return); $ 125,000 (for employees who are married and file separately); or $ 200,000 for all other employees.
@ybakos the overhead being, of course, the costs of
additional bureaucracy (corporate tax return, filings with the State, maintaining records, etc),
additional taxes (state corp taxes, payroll taxes that are not part of
FICA), and
additional operational costs (payroll, mainly).
