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).
FICA taxes are somewhat unique in that there is required withholding from an employee's wages as well as an employer's portion of the taxes that must be paid. The Federal Insurance Contributions Act (FICA) is the federal law that requires you to withhold three separate taxes from the wages you pay your employees. FICA is comprised of: 1  a 6.2 percent Social Security tax; 2  a 1.45 percent Medicare tax (the âregularâ Medicare tax); and. 3  beginning in 2013, a 0.9 percent Medicare surtax when the employee earns over $200,000.
