Enter an IF function in cell G3 on the Payroll Details worksheet to calculate the Social Security tax. Social Security funds are used by the government to provide income for people who are retired, a beneficiary of a retiree, or disabled. An employer must withhold 4.2% of an employee's weekly pay for Social Security. However, an employee is only taxed up to $100,000. The logical test of the IF function should assess if the value in the Pay Year to Date column is greater than or equal to 100000. If the logical test is true, the output of the function should be zero. Otherwise, the function should multiply the value in the Gross Pay This Week by 4.2%. Copy and paste the function into the range G4:G22.
