Is Federal Income Tax Withholding Including Social Security?
Employers withhold several types of payroll taxes from their employees’ paychecks. Each payroll tax withheld from an employee’s check is a separate tax. The employer then submits payment to the appropriate government agency for each payroll tax collected. Payroll taxes withheld from employee paychecks by the employer include federal income tax, state income tax, Social Security tax and Medicare tax.
