If you plan on conducting business with the State or any New Jersey county, municipality, local board of education, charter school, county college, authority, or state college or university, you will be required to be registered with the New Jersey Division of Revenue. In addition, you may be required to submit as part of a public bid or prior to issuing a purchase order a copy of the “proof of registration certificate” to the contracting agency.

To register: Businesses including sole proprietors and general partnerships must complete Form NJ-REG and submit it to the Division of Revenue. The form can be filed online or by mailing a paper form to the Division. Online filing is strongly encouraged.

  • Register online. Click the “online” link and then select “Register for Tax and Employer Purposes.”
  • Download the paper form and instructions
  • Write to the Division at: Client Registration Bureau, PO Box 252, Trenton, NJ 08646-0252.

Note: If you operate a corporation, limited partnership, limited liability company or limited liability partnership and contract with public agencies or have a physical presence in this state, you must obtain legal authority to operate in New Jersey before registering for tax and employer purposes. Generally, this is accomplished by filing an original business certificate with the Division of Revenue, such as a Certificate of Incorporation or Formation. For more information on this subject or call 609.292.9292.

Registering as an individual or as an unincorporated construction contractor:
There is a simplified registration process for individuals doing business with any New Jersey government agency. If you have no tax or employer obligations, you may file Form NJ-REG-A which may be downloaded.

You may also use Form NJ-REG-A if you are an unincorporated construction contractor performing services (Chapter 85, P.L. 2006, defined under N.J.S.A. 54A:7-1.2) in NJ and need to register with the Division of Revenue.

To obtain a copy by mail, call 609.292.9292, or write to the Division of Revenue's Client Registration Bureau at PO Box 252, Trenton, NJ 08646-0252.
