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. The symptoms of an impacted sinus infection are similar to that of a regular case of sinusitis but with a higher intensity of pain and discomfort.
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 federal withholding is for income tax and FICA pays the Social Security tax and medicare tax. The FICA tax has to be matched by your employer, so whatever is deducted from your pay for FICA, double the amount is paid to the IRS. FICA is limited to the first $102,000 of earnings.
