  • Your legal name
  • The Social Security Number (that is if the business owner has no employees and is the sole proprietor) – a sole proprietor has the option of registering with either an Employer Identification number or a Social Security Number 
  • The Employer Identification Number (EIN). Any owner who lacks the EIN should apply for one with the IRS.
  • The starting date of the business 
  • And the business mailing address

Employer Tax Obligations

To begin with, you first have to fully understand who an employer is as defined by the IRS. According to the IRS, an employer can be a person, a corporation, or an organization that hires individuals to perform some service as skilled workers or employees.

A Massachusetts employer’s responsibilities include:

  • Ensuring that the business is registered with the Massachusetts Revenue Department so as to withhold the employees’ wages income taxes. You may learn more about the type of taxes that you’re supposed to register for by visiting the Business Taxes. 
  • Asking every employee to hand in a completed federal form W-4, which is the Employee Withholding Allowance Certificate.
  • If required, ask the employees to hand in a completed Massachusetts Employee’s Withholding Exemption Certificate, also known as Form M-4. An M-4 is only important when one of your employees feels the need to claim a different withholding exemption number. 
  • Withholding child support payments and/or tax from the employees’ paychecks or independent contractors, and forwarding those finances to the Revenue Department, if ordered to do so by a court or the Revenue Department. 
  • Making sure that they file the quarterly reports of wages that have been paid to every employee who lives or is employed in Massachusetts. 
  • Ensuring all the employees have a wage, Tax Statement, and Form W-2 by the 31st of January, or within 30 days in a case where the employment gets terminated before the year ends. The W-2 form has to indicate: the sum of all wages paid, the total Medicare taxes withheld and Social Security, the total amount of Massachusetts and federal income tax withheld for the prior year, and file copies of the Massachusetts Department of Revenue’s W-2 forms, if required. The information obtained from the W-2 has to be filed with the Social Security Administration. 
  • Fulfilling the state employment security tax obligations and registering with the Massachusetts Unemployment Department.
  • Ensuring all the employees in your organization have the workers’ compensation insurance before they start working for you.
