An impacted sinus infection is when the pressure from the sinus infection begins to affect other parts of the body, such as the teeth, the eyes and the brain.

An employer's federal payroll tax responsibilities include withholding from an employee's compensation and paying an employer's contribution for Social Security and Medicare taxes under the Federal Insurance Contributions Act (FICA).
The chief distinction is that state withholding is based on state-level taxable income and federal withholding uses federal taxable dollars. State withholding rules tend to vary among the states, while federal withholding rules are consistent everywhere throughout the United States. How Withholding Works. Both state and local governments may impose withholding on wage income, but only based on the state taxes; they may not withhold federal income taxes. Employers can be required to automatically deduct withholding from their employees' paychecks for federal and state income taxes and Social Security taxes.
