What is the difference between an Employer account and a Third-Party account?

The option to register for an Employer Account means you are accessing the New Jersey Employer Services Portal to obtain or provide information regarding your company and its employees. Please be aware if you are a Third-Party Company or person such as a bookkeeper or payroll company registering an account on behalf of an Employer, the Employer must register you to do business of their behalf. To do business in the Portal, an Employer must complete their own registration and accept their own Terms of Agreement.

The option to register for a Third-Party Account means you are not the Employer, rather a company or person (s) such as a bookkeeper, payroll company, or health plan administrator, given authority by an Employer to handle a specific responsibility on their behalf.

Please Note - It may be appropriate for a Third-Party Company to register for both Account Types. Registering a Third-Party account would allow the Third-Party Company to receive a request from another Employer to work on their behalf.

What is the role of the Account Administrator?

The Account Administrator has the authorization to:

  • Request additional Users to have access to online functions
  • Manage additional Users for the registered company
  • Maintain all contact information for the registered company
  • Approve or Deny requests for a Third-Party Company to work on behalf of an Employer

After the Account Administrator receives notification that the account has been approved, individuals designated, by the administrator, will receive email notification with instruction to complete their registration to enable access.

  • Payroll: The company representative assigned as a Payroll User is authorized to report employee new hires.

What are the roles of a Third-Party company?

Be aware that Users within a Third-Party Company have a two-part assignment.

The main difference between those two User Types:

A Third Party can manage the Third-Party Company information and manage requests from Employers.

The second role for Third Party Users is assigned by the Employer. When an Employer requests a Third-Party Company to work on their behalf, they allow them access for Payroll and Medical.
