Earnings deducted from an employee’s paycheck for the payment of taxes, benefits, or withholdings are known as payroll deductions. Payroll deductions are both required and optional. Since certain deductions are made pre-tax, and others are made post-tax, the sequence in which they are taken out of paychecks is also important.
Employees can donate revenue automatically to an ongoing cost or investment through payroll deduction arrangements. Some payroll deduction arrangements may also include systematic, voluntary payroll deductions for the acquisition of common stock.
