Which of the following is an employer not required to withhold from the paychecks of its employees?

Workers' compensation insurance is not withheld from employees' paychecks in the same manner as federal payroll taxes like Social Security, Medicare, or income tax. Instead, employers are typically responsible for paying for workers' compensation insurance premiums, which provide benefits for employees who are injured in the course of their work. This is a critical distinction, as employees do not see a direct deduction from their pay for workers' compensation, while Social Security, Medicare, and income taxes are systematically deducted each pay period. Understanding this difference is essential for compliance with tax laws and for ensuring that employees are aware of what deductions they can expect from their earnings.
