Income Tax Withholding Income tax withholding is the withholding of a portion of employee wages for state and federal income tax purposes. As a general rule, the owner of a business that is incorporated is also considered an employee for withholding tax purposes. If you were the sole proprietor of a business that has no other employees, you would not be considered an employee and would not be required to register for withholding tax.
