Which of the following is NOT a required employee deduction?

Workers' Compensation is generally not considered a required employee deduction in the same way that Federal Tax, State Tax, and Social Security taxes are. These three are required deductions mandated by federal and state laws, impacting an employee's take-home pay.

Federal Tax is deducted from employees’ wages based on their income level and filing status as determined by the IRS. State Tax follows similar principles but varies by state, with specific rates and regulations dictating the amount deducted from an employee’s paycheck.

Social Security taxes are contributions to the federal program that provides retirement, disability, and survivor benefits, and it is similarly required by law for all employees.

In contrast, Workers' Compensation insurance is typically provided by employers to cover employee liabilities resulting from work-related injuries or illnesses. While it is crucial for protecting both employees and employers, the costs associated with Workers' Compensation do not come out of employees' gross wages and thus is not classified as a deduction from paychecks. This differentiates it from the other listed options, solidifying why it does not fit within the context of required employee deductions.
