Go to the IRS website and apply for a federal identification number, which will become your New Jersey taxpayer identification number. All LLCs with multiple owners, or members, or that have employees must have this number. An LLC with a sole member and no employees, in most cases, will not need this number and the sole member can use his Social Security number. Complete the application online or apply by phone, mail or fax.
Access the Treasury Department's website to obtain the New Hire Reporting Form if this is the first time the LLC is registering. Download and print the form. Enter your federal employer identification number. Mail the completed form to the New Jersey New Hire Operations Center in Trenton, or access the center's website to register new hires online.
Obtain the business registration packet from the Treasury Department's website or by calling the client registration hotline at 609-292-9292 to request it. The packet contains the two forms you need to register, Business Registration Form (NJ-REG) and Public Records for Filing New Business Entity. You can also register by completing both forms online at the New Jersey Business Gateway Service website.
Review the instructions to identify the documents and information your LLC will need to answer the questions on both forms. For example, the instructions will tell you the New Jersey Business Code and Municipality Code for your LLC. Also know the date you formed the business and date you plan to open. Know whether you will be paying wages to employees who live outside New Jersey and if you will be collecting sales tax.
Fill out the NJ-REG form in the packet. Download and print the form or access the online version. Enter your federal identification number. Enter the 10-digit NJ Business Corporation Number. Have the form signed by an owner, partner or officer of the LLC.
Download and print the Public Records Filing for New Business Entity form in the same packet, or access the form online. Complete the application, which requires a $125 fee. Send the completed NJ-REG and Public Records Filing forms to the Division of Revenue along with the check covering the fee, or submit both applications online.
Confirm the registration status of the business by obtaining a Business Registration Certificate. New businesses can receive the certificate by answering “yes” to the question that asks about contractor and subcontractor issues if your LLC intends to render services to the state, local government, public and charter schools or to state colleges and universities. If you have previously registered, submit an online form or send a request by email or regular mail to the Division of Revenue.
