How to File the NJ-REG New Jersey Business Registration Form

To file the NJ-REG, submit New Jersey’s Business Registration Application online at njportal.com/DOR/BusinessRegistration at least 15 business days before you start doing business in the state. There’s no fee for the NJ-REG itself, and completing it is what makes you eligible for the Business Registration Certificate you’ll need for any public contract, state grant, or tax credit.¹²

The form registers your business with the Division of Revenue and Enterprise Services for the specific state taxes that apply to you: sales and use tax, employer withholding, and any industry-specific taxes.

When You Have to File and Who’s Covered

File at least 15 business days before your first day of business in New Jersey. The Division of Taxation applies this to any person or entity doing business in the state, including individuals selling at flea markets or craft shows and nonprofit organizations.¹

You need to register if any of these describe you:

You sell taxable goods or services in New Jersey and must collect sales tax.
You have employees and must withhold payroll taxes.
You contract with New Jersey state agencies, counties, municipalities, local school boards, or state colleges and universities. Under N.J.S.A. 52:32-44, contractors and subcontractors must present a Business Registration Certificate before any contract, purchase order, or agreement is awarded.³

A physical location isn’t required. Out-of-state sellers must register once they cross either threshold in the current or prior calendar year: more than $100,000 in gross revenue from New Jersey sales, or 200 or more separate transactions delivered into the state.⁴

Form Your Entity First If You’re an LLC or Corporation

If your business is a corporation, LLC, limited partnership, or limited liability partnership, you can’t file the NJ-REG until you’ve filed your formation documents. Domestic entities file a Certificate of Formation; out-of-state entities file a Certificate of Authority. The fee is $125 for for-profit entities and foreign nonprofit corporations, or $75 for domestic nonprofit corporations. Filing runs through the state’s Business Formation portal, and once it’s processed you receive a ten-digit Business Entity ID that the NJ-REG requires.²

Sole proprietorships and general partnerships skip formation entirely and go directly to the NJ-REG, using a federal EIN (or, for sole proprietors without employees, a Social Security Number) as the identifier.⁵

What to Have Ready Before You Start

The online form can’t be saved mid-session, so pull everything together first.

Federal EIN. Corporations, LLCs, and limited partnerships need one. You can apply through the IRS online and receive it immediately.⁶ Sole proprietors without employees may use an SSN, though the state recommends getting an EIN regardless.⁷

Business Entity ID. The ten-digit number assigned when your formation certificate was processed. General partnerships and sole proprietorships don’t have one.⁵

NJ Business Code and NAICS code. The NJ Business Code is a state-specific classification from the Division of Revenue’s published list. The NAICS code is a six-digit federal classification searchable on the Census Bureau’s NAICS site. Picking the wrong code can cause confusion later about which tax obligations apply to you.⁸

Tax type selections. During the form you’ll flag which taxes apply. The common ones:

Sales and Use Tax, if you sell taxable goods or services. New Jersey’s rate is 6.625% on most tangible personal property, specified digital products, and certain services.⁹
Employer Withholding Tax, if you pay employees.
Specialty taxes tied to your industry, such as the Petroleum Products Gross Receipts Tax or the Litter Control Fee, which applies to manufacturers, wholesalers, distributors, and retailers of litter-generating products sold in New Jersey.¹⁰

S Corporation documents. If your business has elected federal S Corp or Qualified Subchapter S Subsidiary status, have the federal election letter and each shareholder’s SSN or EIN handy. If you’ve applied to the IRS but haven’t received the acceptance letter, skip that section during initial registration and update it later through the state’s online S Corporation application.⁸

File the Form Online

Go to njportal.com/DOR/BusinessRegistration. The portal validates entries as you go, which catches typos and mismatched ID numbers before they become processing delays. When you submit, you’ll receive a confirmation number. Save it. You’ll also gain access to NJ Premier Business Services, the state’s portal for electronic tax filing, payments, and account history.⁸¹¹

If You Have to File on Paper

A paper NJ-REG goes by mail to the Division of Revenue, Trenton, NJ 08625-0628. Paper processing takes several weeks rather than days, so use this route only if you can’t file electronically.

Get Your Business Registration Certificate

Once the NJ-REG is processed, print your Business Registration Certificate through the state’s online BRC lookup. You enter your Name Control (the first four characters of your business name) along with either your Taxpayer ID or Business Entity ID.¹²

Format the Taxpayer ID as twelve digits: your nine-digit federal EIN followed by three zeros (or your three-digit suffix if you have one). The Business Entity ID is entered with all ten digits, leading zeros included. No spaces, dashes, or slashes.¹²

The certificate is what proves you’re registered and in good standing when you bid on public contracts or apply for state grants and tax credits.²

Updating or Closing Your Registration

Once you’re registered, most changes go through Form REG-C-L. You can file it online to update your mailing address, add or end tax eligibilities, switch between year-round and seasonal cycles, adjust electronic fund transfer payment registrations, replace a temporary tax/employer ID with the official one, or update filing status for partnerships and sole proprietorships. Two situations require a paper REG-C-L: registering an additional location, and reporting a purchase or sale of the business with new owners.¹³

REG-C-L doesn’t cover everything. If you change your legal structure — a sole proprietorship converting to an LLC, for example — the state treats the result as a new business, and you’ll need to file formation documents and a fresh NJ-REG. Amendments to original charter documents like certificates of incorporation also fall outside REG-C-L.¹³

If you stop operating and no longer need to collect sales tax, file Form C-6205-ST with the Division of Taxation to request non-reporting status. To end individual tax eligibilities without fully closing, use REG-C-L online. Simply not filing returns will generate penalties and collection activity.¹³

What Happens If You Don’t File

Failure to register results in penalties and fees on taxes owed to the state.⁷ An unregistered business also can’t obtain a Business Registration Certificate, which shuts it out of any contract with a state agency, county, municipality, school board, or state college.³ And a business that has been collecting sales tax without being registered is holding money that legally belongs to the state, with no authorized channel to remit it. The 15-business-day advance filing requirement is designed to set up your tax accounts before your first taxable transaction, so file early rather than after the fact.¹
