The NJ-REG form is New Jersey’s combined tax and employer registration application, filed with the Division of Revenue and Enterprise Services to obtain a state tax identification number and a Business Registration Certificate.1Division of Revenue and Enterprise Services. Getting Registered The form itself costs nothing to file. Most businesses, though, have to complete an entity-formation filing first, and that one carries a fee.
Any business that operates in New Jersey — selling taxable goods, hiring employees, or earning income in the state — must register through NJ-REG.2State of New Jersey. New Jersey Business and Employer Registration The registration covers three tax categories: income-based taxes on net profits, sales and use tax if you sell taxable goods or services, and payroll taxes if you have employees.3Business.NJ.gov.

What to Do Before You File
Corporations, LLCs, limited liability partnerships, and limited partnerships must handle two things before submitting the NJ-REG. First, get a federal Employer Identification Number from the IRS. Second, file a certificate of formation or authorization with the Division of Revenue. The formation filing costs $125 for all for-profit entities and foreign nonprofits, or $75 for domestic nonprofits.1Division of Revenue and Enterprise Services. Getting Registered
General partnerships and any business with employees also need an EIN first, but they skip the entity-formation step. Sole proprietors without employees can use their Social Security Number in place of an EIN, though the Division of Revenue recommends getting an EIN anyway.2State of New Jersey.

Information to Have Ready
Before opening the form, gather:
- Your federal EIN or SSN. Corporations, LLCs, and limited partnerships must use their EIN together with their NJ Business Entity ID. Partnerships and sole proprietorships can use either.2State of New Jersey. New Jersey Business and Employer Registration
- Your legal business name, exactly as it appears on formation documents. Any trade name or DBA goes in a separate field.
- A physical business address. A P.O. box alone will not satisfy the primary-address field.
- The date your operations began in New Jersey.
- Your business structure (corporation, LLC, partnership, sole proprietorship, or other). The Division uses this to classify your tax obligations.
- Your six-digit NAICS code describing your industry.
- The tax types you need to register for, such as sales tax collection and payroll withholding.
How to File
Online
The fastest route is the state’s Online Business and Employer Registration Service at njportal.com.4State of New Jersey. Online Tax/Employer Registration The system walks through each section, validates entries in real time, and flags problems before submission. You certify the information at the end and submit electronically. Filing itself is free; associated fees like the $125 formation fee can be paid by credit card or e-check.5Division of Revenue and Enterprise Services. Registry Fee Schedules
Once you submit, the system generates a confirmation receipt with a tracking number. Hold onto it. That receipt is your proof of filing date and your reference for any follow-up. Online registrations are generally processed within a few business days.
By Mail
You can also print and mail a completed NJ-REG to the Division of Revenue and Enterprise Services. The form must be legible and every section filled in; incomplete paper applications get returned. Paper processing takes noticeably longer, often several weeks depending on volume. For mailed payments, check the Division’s current instructions for accepted methods.
What You Receive
After the Division processes your NJ-REG, you get a Business Registration Certificate. This document shows that the Department of the Treasury recognizes your business and that you are registered for state taxes. Your New Jersey tax identification number — your federal EIN with a three-digit suffix — appears on the certificate and is what you’ll use for every state tax filing going forward.3Business.NJ.gov. Register for Taxes
If you indicated on the NJ-REG that you’ll collect sales tax, you’ll also receive a Certificate of Authority to Collect Sales Tax. Display it at your place of business as required.
To verify your registration later or retrieve the certificate, use the Division’s Business Registration Certificate lookup service. You’ll enter your 12-digit tax ID: the nine-digit EIN followed by your three-digit suffix, or three zeros if you don’t have one.6New Jersey Department of Treasury – Division of Revenue.

Keeping the Registration Active
Every registered business entity in New Jersey must file an annual report to stay in active status. The report is due on the last day of the month in which you originally formed your business and carries a $75 filing fee. The state does not send reminders, so track the date yourself. Missing it can lead to revocation of your registration.7Business.NJ.gov. Taxes and Annual Report
If your address, registered agent, or other details change, update them through the annual report or by contacting the Division of Revenue directly. Outdated information causes problems with tax correspondence and compliance notices.
What Happens If You Don’t Register
Operating in New Jersey without filing the NJ-REG exposes your business to penalties and fees on any taxes you owe. Not having an EIN can also prevent you from filing taxes correctly, which triggers further consequences.8Business.NJ.gov. Register Your Business An unregistered business also cannot obtain a Business Registration Certificate, which closes off government contracting work and can create friction with vendors or financial institutions that want proof of state registration.
