Multistate Employer Registration Form for New Hire Reporting
If you are an employer with employees in two or more states and you want to report all new hires to one state, you must register with the U.S. Department of Health and Human Services. You have two options to register.
Note: To report new hires to a single designated state or territory, you must register as a multistate employer.
How to Register as a Multistate Employer or Make Changes to a Previous Registration
Option 1: Register as a new user on the Office of Child Support Enforcement (OCSE) Child Support Portal or login to access the Multistate Employer Registration (MSER).
Option 2: Fill out and email this form to [email protected].
Note: If you are a third-party provider, your clients must have employees in two or more states to register as a multistate employer.
Reporting Requirement
Federal law (42 U.S.C. § 653A(b)(1)(A)) requires employers to provide the following information about newly hired or rehired employees to the State Directory of New Hires in the state where the employee works:
Employee’s name, address, Social Security number, and the date of hire (the date services for remuneration were first performed by the employee)
Employer’s name, address, and Federal Employer Identification Number (FEIN)
If you are an employer with employees working in two or more states, and you will transmit the required information or reports magnetically or electronically, you can use this form to designate one state where any employee works to transmit all new hire reports to the State Directory of New Hires.
