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. (However, as the owner you are required to make individual estimated income tax payments if you expect to owe more than $400 in Massachusetts income tax on the income you receive from the business. See Sole Proprietorships, Estimated Payments.)
The amount you withhold from your employees for state income tax purposes should be based on Form M-4 , Massachusetts Employee's Withholding Exemption Certificate (submitted to you by each employee), and on Circular M , Massachusetts Income Tax Withholding Tables. A detailed explanation of how to use the tables or a percentage method for automated payroll systems is provided in Circular M.
The Internal Revenue Service and Social Security Administration also require employers to withhold federal income tax and Social Security contributions from employee wages. Resources for obtaining additional information about your federal obligations are listed in the section of this guide.
