New Jersey Form NJ-REG is the Business Registration Application that every person or entity doing business in New Jersey must file with the New Jersey Division of Revenue and Enterprise Services (DORES) to register for state taxes, employer obligations, and to receive a Business Registration Certificate (BRC). You must file NJ-REG at least 15 days before you start collecting sales tax and within 60 days of forming a business entity in the state, or you risk penalties, blocked tax filings, and the inability to bid on public contracts.
According to the New Jersey Department of the Treasury, the state processes more than 75,000 new business registrations every year, and a significant share are rejected on first submission for missing NAICS codes, mismatched ownership data, or incorrect “begin date” entries. This article walks you through each line of the current online NJ-REG (and the paper PDF version) so you file once, correctly, the first time.
Here’s what you’ll learn:
- 📋 Exactly how to complete every section of NJ-REG, line by line, using the official field names from the online NJ-REG portal.
- 🧾 Three real-world filer scenarios — a sole proprietor, an LLC with employees, and an out-of-state corporation — with full sample entries.
- ⚠️ The most common mistakes filers make on Section H (employer registration) and the sales tax checkbox, and how to avoid them.
- 💵 The deadlines, fees, and penalties tied to NJ-REG, including the $200–$1,000 foreign-entity fines for late filing.
- 🛠 How to file through the online portal, by mail, or in person, and what to keep as proof of filing.
What Form NJ-REG Is and Who Must File It
Form NJ-REG is the official tax and employer registration application for the State of New Jersey, administered by the Division of Revenue and Enterprise Services under the Department of the Treasury. The form serves three jobs at once. It registers your business for New Jersey tax purposes, sets up your accounts for sales tax, withholding tax, and unemployment insurance, and produces the Business Registration Certificate (BRC) required for any public contracting work in the state.
Every entity doing business in New Jersey must file. That includes corporations, S-corps, LLCs, LLPs, limited partnerships, general partnerships, sole proprietors, and self-employed individuals making occasional sales, as the NJ Division of Taxation explains for vendors. It also includes nonprofits, contractors performing public works, and out-of-state (“foreign”) entities with New Jersey nexus. Even a freelancer who sells one taxable item at a craft fair must register before that first sale.
The statutory authority comes from N.J.S.A. 54:32B (the Sales and Use Tax Act), N.J.S.A. 43:21 (the Unemployment Compensation Law), and N.J.S.A. 54:50 (general state tax administration). The plain-English meaning is that New Jersey requires every business to identify itself, declare what taxes it will owe, and provide ownership information so the state can collect what it is owed. The consequence of skipping registration is steep, as Onal Gallant’s guide on NJ business registration notes — foreign LLCs face $200 fines per partial year of unregistered activity, and foreign corporations and LPs face penalties ranging from $200 to $1,000. A real-world example is a Pennsylvania contractor who completes three jobs in Bergen County over two years without registering. That contractor cannot sue an unpaid client in New Jersey court until they register and pay back fines. A common misconception is that small “side hustles” are exempt — they are not.
Before You Start: Documents and Information You Need
NJ-REG looks short, but the form pulls data from at least eight other documents. Gather everything below before you open the online registration portal, or you’ll be forced to restart your session. The portal does not let you save and return.
- Federal Employer Identification Number (EIN). Every corporation, LLC, LLP, LP, and partnership must have one. Sole proprietors without employees may use an SSN but should still apply for an EIN through the IRS EIN Assistant. Without an EIN (or SSN where allowed), the system blocks submission.
- New Jersey Business Entity ID (10-digit number). Issued when you file your Public Records Filing for New Business Entity (Certificate of Formation/Authorization). LLCs, corporations, and LPs cannot complete NJ-REG without this number, available through the NJ Business Formation portal.
- Exact legal business name and trade name (DBA). Must match the Public Records Filing letter-for-letter. A typo here causes a “name mismatch” error and forces a paper amendment later.
- NAICS code (6 digits). The federal North American Industry Classification System code that best describes your primary activity. Pulling the wrong code triggers wrong tax-account setup (e.g., missing the construction industry contractor flag).
- Date business activities began or will begin in New Jersey. This is the “begin date” and it controls when filings are due. Picking a date in the past creates back-tax exposure.
- Anticipated first payroll date if you will hire W-2 employees. This opens your withholding and unemployment insurance accounts.
- Estimated annual gross sales and whether you’ll collect New Jersey sales tax. This determines whether you receive a Certificate of Authority.
- Names, titles, SSNs, addresses, and percentage ownership of each owner, partner, member, or officer. Required in the disclosure section. Missing or partial owner data is the single most common cause of rejection.
- Business street address (not just a P.O. Box). New Jersey requires a physical location. P.O. Boxes are allowed only as the mailing address.
- A working email address and phone number for the business contact who will receive your BRC and Certificate of Authority.
If any item is missing, the application either errors out, generates a wrong account type, or returns a BRC that cannot be used for public contracting bids. The fix later is a Registration Change and Amendment filing, which delays everything by 2–4 weeks.
Where to Get the Form and How to Access It
The fastest, free, and recommended path is the State of New Jersey Online Tax/Employer Registration on the NJ Portal, operated by DORES. This is the live online NJ-REG and replaces most paper filings. The portal is open 24/7 and issues a confirmation number the instant you submit. You should bookmark it because the portal does not allow saving partial sessions.
For filers who cannot use the online tool — for example, certain foreign entities with no EIN yet, or filers requiring wet-ink signatures — a paper Form NJ-REG PDF packet is available. The paper packet contains the registration form (page numbered NJ-REG (8-15) on the most recent revision), instructions, and supplemental schedules. Always confirm the revision date printed in the lower-left corner of page 1 before filing; using an outdated revision is grounds for rejection.
If your business is an unincorporated individual contractor with no employees and no sales tax exposure, you may file the simpler Form REG-A instead, also covered in the same packet. Nonprofits seeking sales tax exemption file NJ-REG and then submit Form REG-1E separately. For tax-only registration changes after initial filing, use the online Registration Change Service. For amendments to ownership or entity structure, use Form REG-C-L (legal name/entity) or REG-C-EA (entity amendment), depending on the change.
You can also get help by phone. The DORES Business Registration Services Office at 609-292-9292 (Option 1) answers field-by-field questions Monday through Friday, 8:30 a.m. to 4:30 p.m., as listed on the NJ Division of Taxation vendor information page. Email questions go to taxrevops@treas.nj.gov.
Step-by-Step: How to Fill Out NJ-REG Line by Line
The online NJ-REG is grouped into ten sections, A through J. The paper version uses the same section letters. Follow the order on the form — skipping ahead and returning often resets prior fields in the online portal.
Section A: Reason for Filing
What this field asks in plain English. Section A asks why you are submitting the form. The choices include “Original application for a new business,” “Application for a new location of an existing registered business,” “Amended application,” and “Application for reinstatement.”
How to answer it. Check exactly one box. New filers almost always check Original application for a new business. If you are adding a new branch or location to a business already registered with DORES, check Application for a new location.
A specific example answer. Maria Lopez is opening a new home-staging LLC in Newark. She checks Original application for a new business and writes her start date 07/01/2026 in the adjacent date field.
A nuance or edge case. If you previously dissolved a New Jersey entity and are forming a brand-new entity (even with the same trade name), you still check Original application, not Reinstatement. Reinstatement applies only to the same legal entity returning from suspended status.
A common mistake on this field and its direct consequence. Filers checking Amended application when they really mean Original triggers DORES to look for a prior registration that does not exist, which freezes the application until a manual reviewer clears it.
A misconception people hold about this field. Many filers think that filing the Public Records Filing for an LLC counts as the “original application” referenced in Section A. It does not. Section A refers to NJ-REG itself, not the entity formation filing.
Section B: Business Identification — Legal Name, Trade Name, and FEIN
What this field asks in plain English. Section B asks for your full legal business name, any trade name (DBA) you use publicly, and your Federal EIN.
How to answer it. Type the legal name exactly as it appears on your IRS EIN confirmation letter (CP 575) and your New Jersey Public Records Filing. Use uppercase if the official record is uppercase. Trade names go in the DBA box only if your DBA is registered with the county clerk (sole props) or is the same as your legal name (LLCs/corps).
A specific example answer. LOPEZ HOME STAGING LLC in the legal name box. Maria’s Home Staging in the trade name box. 87-1234567 in the FEIN box, exactly as IRS issued it.
A nuance or edge case. If your legal entity has special characters (commas, periods, ampersands), match them precisely. Smith, Jones & Co., LLC is not the same as Smith Jones and Co LLC in the DORES match logic.
A common mistake on this field and its direct consequence. Entering the EIN with dashes when the system expects a 9-digit string (or vice versa) returns a “Federal ID not recognized” error and ends the session.
A misconception people hold about this field. Filers often believe a sole proprietor’s SSN is interchangeable with an EIN here. It is — but only for sole proprietors with no employees. Once you hire your first W-2 worker, you must amend Section B to your EIN.
Section C: Business Type and Entity Classification
What this field asks in plain English. Section C asks what type of business entity you are: sole proprietor, partnership, LLC, corporation, S-corp, nonprofit, etc.
How to answer it. Check the single box that matches your formation documents. LLCs taxed as partnerships still check LLC. LLCs that elected S-corp status check LLC and complete the S-corp box at the bottom.
A specific example answer. Marcus Johnson formed a multi-member LLC. He checks Limited Liability Company, then enters his NJ Business Entity ID 0450123456 and his date of formation 03/15/2026.
A nuance or edge case. If you operate under a fictitious name as a sole proprietor (a “trade name”), check Sole Proprietor — not “DBA,” which is not a recognized entity type. Trade name registration is a separate filing at the county level.
A common mistake on this field and its direct consequence. Marking Corporation for a single-member LLC because it “feels professional” causes DORES to set up a CBT (Corporation Business Tax) account that must then be closed manually, delaying your BRC.
A misconception people hold about this field. Many filers think the federal tax classification (e.g., disregarded entity vs. S-corp) controls Section C. It does not. New Jersey Section C reflects the state-law entity type, not federal tax election.
Section D: Mailing and Business Address
What this field asks in plain English. Section D asks where the business is physically located in New Jersey and where DORES should mail tax notices.
How to answer it. Enter the physical street address in the Business Location fields. Use the Mailing Address fields only if mail goes somewhere different — such as a P.O. Box or accountant’s office.
A specific example answer. Janet Park lists her physical location as 128 Bloomfield Ave, Suite 3, Montclair, NJ 07042 and her mailing address as P.O. Box 91, Montclair, NJ 07042.
A nuance or edge case. If you operate from home, use the home address. If you have a virtual office or coworking space, the lease must show the business as a tenant for the address to qualify. Pure mail-drop addresses (UPS Store boxes labeled as suites) often trigger a manual review.
A common mistake on this field and its direct consequence. Putting a P.O. Box in the Business Location field causes the system to flag the registration as “no physical presence,” which can delay the Certificate of Authority by weeks.
A misconception people hold about this field. Filers think changing the address later is fine. It is — but only via the online Registration Change Service. Updating address with the IRS does not flow to New Jersey.
Section E: NAICS Code and Description of Business Activity
What this field asks in plain English. Section E asks for the 6-digit NAICS code that best describes what your business actually does, plus a short narrative description.
How to answer it. Look up your NAICS code at census.gov/naics. Pick the most specific 6-digit code, not the 2-digit sector. In the description box, write a one-sentence plain description: Residential interior staging and decluttering services for real estate listings.
A specific example answer. Maria Lopez enters 541410 (Interior Design Services) and the description above.
A nuance or edge case. If you have two distinct lines of business (say, retail sales and consulting), choose the code for the activity producing the most revenue. You can list secondary NAICS later through a registration change.
A common mistake on this field and its direct consequence. Choosing a generic code like 999999 or 541990 when a more specific code exists can mis-route your file and exclude you from industry-specific tax credits.
A misconception people hold about this field. Filers believe the NAICS code is permanent. It isn’t — you can update it after a pivot, but the original code is what determines your initial tax account configuration.
Section F: Business Activity Begin Date
What this field asks in plain English. Section F asks the exact date you started or will start operating in New Jersey.
How to answer it. Use MM/DD/YYYY format. Pick the date you actually opened the doors, accepted a first customer, hired a first employee, or signed a first contract — whichever came first.
A specific example answer. Carlos Rivera, an out-of-state Delaware corporation expanding into NJ, enters 06/01/2026 — the date his first sales rep started taking NJ orders.
A nuance or edge case. If you formed your LLC months before any actual activity, do not use the formation date. Use the actual operations start date. Otherwise, you’ll owe minimum tax for “dormant” months you never operated.
A common mistake on this field and its direct consequence. Backdating to the formation date triggers retroactive Sales and Use Tax, withholding, and CBT minimum tax obligations. Each missed quarterly filing carries a $100 minimum penalty.
A misconception people hold about this field. Filers think future-dating the begin date avoids the 15-day pre-sales-tax requirement. It can — but only if the date is genuinely accurate. DORES cross-checks bank account opening dates and merchant processor activations.
Section G: Sales and Use Tax Registration
What this field asks in plain English. Section G asks whether you’ll collect New Jersey sales tax, whether you sell taxable services, and whether you’ll buy items for resale.
How to answer it. Check Yes for “Will you collect New Jersey Sales Tax?” if you sell tangible personal property, prepared food, or specified taxable services in New Jersey. Provide the start date for sales tax collection (must be within 15 days of submitting NJ-REG, per the NJ Division of Taxation vendor rules).
A specific example answer. Aisha Brown opens an Etsy-fulfilled candle company shipping from Jersey City. She checks Yes, lists 07/15/2026 as her sales tax start date, and checks Yes on the resale certificate question because she buys wax wholesale.
A nuance or edge case. Out-of-state sellers triggering economic nexus ($100,000 in NJ sales or 200 transactions per year) must register here too, per N.J.S.A. 54:32B. Marketplace facilitators handle some of this, but direct-to-consumer sales still require your own Certificate of Authority.
A common mistake on this field and its direct consequence. Checking No on sales tax because you “only sell online” leads DORES to issue no Certificate of Authority. The first time you collect $1 of NJ sales tax without a certificate, you owe a penalty plus interest on every taxable sale, as outlined in this New Jersey sales tax permit guide.
A misconception people hold about this field. Filers think the resale certificate is automatic. It is not — you must check the resale box in Section G to receive resale certificate (Form ST-3) authority.
Section H: Employer Registration (Withholding and Unemployment)
What this field asks in plain English. Section H asks whether you have or expect to hire W-2 employees in New Jersey, and the date wages first will be paid.
How to answer it. Check Yes for “Will you have employees in New Jersey?” only if you’ll issue W-2s to workers performing services in NJ. Enter the first payroll date in MM/DD/YYYY format. The system opens a Withholding Tax (NJ-927) account, an Unemployment Insurance account, and a Disability Insurance account simultaneously.
A specific example answer. Marcus Johnson hires his first office assistant. He checks Yes, enters 08/01/2026 as his first payroll date, and confirms his estimated annual NJ wages at $60,000.
A nuance or edge case. Independent contractors (1099 workers) do not count as employees here. But misclassifying a worker triggers an audit under the New Jersey “ABC Test” (N.J.S.A. 43:21-19(i)(6)), which can reclassify and assess back UI taxes.
A common mistake on this field and its direct consequence. Checking No because you “only pay yourself as the owner” of an LLC — when in fact the LLC has elected S-corp status and pays you a W-2 salary — leaves you without a withholding account. Your first payroll then bounces back, and you face penalties for late employer registration.
A misconception people hold about this field. Filers think federal W-4 setup also handles the New Jersey side. It doesn’t. New Jersey requires its own NJ-W4 process tied to the account opened through Section H.
Section I: Public Contracts, Special Industries, and Other Tax Types
What this field asks in plain English. Section I asks whether your business is subject to specialized New Jersey taxes — Cigarette Tax, Motor Fuels, Alcoholic Beverage Tax, Litter Tax, public works contracting, and similar industry overlays.
How to answer it. Check every box that applies. Most general filers leave this section blank. Construction contractors who plan to bid on public contracts must check the Public Works Contractor box and complete supplemental Form PW-1.
A specific example answer. Janet Park, a divorce attorney, leaves Section I blank. Carlos Rivera’s Delaware corporation, which sells e-cigarette liquids, checks the Tobacco Products Wholesale Sales Tax box.
A nuance or edge case. Some boxes (alcoholic beverage, motor fuels) require additional licensing through other agencies (ABC, Motor Fuel Tax Bureau) before NJ-REG can finish processing.
A common mistake on this field and its direct consequence. Skipping the Litter Tax box for businesses that sell qualifying products (paper, food, soft drinks, etc.) means you’ll under-report and face back-tax assessments under N.J.S.A. 13:1E-216.
A misconception people hold about this field. Filers think Section I is “advanced” and only relevant to large companies. Many small retail and food businesses owe Litter Tax — it’s the most overlooked tax in the state.
Section J: Owner, Partner, Officer, or Member Disclosure
What this field asks in plain English. Section J asks for the name, title, SSN, home address, and percent ownership of every owner, partner, member, or officer.
How to answer it. List each person on a separate line. Include first name, middle initial, last name, SSN (no dashes), title (Member, Partner, President, etc.), home address, and ownership percentage. Percentages must total 100% for partnerships and LLCs.
A specific example answer. Marcus Johnson and his co-founder Priya Shah each own 50% of their LLC. Marcus enters MARCUS JOHNSON, SSN 123456789, Member, 50%, with his home address. He adds Priya on the next line: PRIYA SHAH, SSN 987654321, Member, 50%.
A nuance or edge case. Single-member LLCs list one person at 100%. Corporations list officers (President, Treasurer, Secretary) even if they hold no equity, because New Jersey requires officer disclosure for tax assessment notices.
A common mistake on this field and its direct consequence. Listing percentages that don’t sum to 100% (e.g., two members at 40% each) is the most common cause of NJ-REG rejection. The system stops processing and you must restart Section J.
A misconception people hold about this field. Filers think trust- or holding-company-owned interests can be summarized as “Trust 100%.” They cannot — you must list the trustee or controlling individual by name and SSN.
Signature and Certification
What this field asks in plain English. The final block asks an authorized officer, partner, or owner to certify under penalty of perjury that the information is accurate.
How to answer it. Type your full name, title, and date in the e-signature block on the online portal. On paper, sign in blue ink and date.
A specific example answer. Maria Lopez, Sole Member, 06/15/2026.
A nuance or edge case. Tax preparers, attorneys, and CPAs may sign for clients only if they have a Power of Attorney (Form M-5008-R) on file with DORES. Otherwise, the owner must sign personally.
A common mistake on this field and its direct consequence. Letting a bookkeeper sign without a POA voids the application. DORES treats unsigned applications as never filed, which retroactively invalidates the begin date.
A misconception people hold about this field. Filers think an electronic signature on the online portal is somehow less binding than wet ink. It carries identical legal weight under the New Jersey Uniform Electronic Transactions Act.

How to File the Completed Form
NJ-REG accepts three filing channels, each with different fees, processing times, and proofs of filing. Pick the channel that fits your situation, and keep the confirmation number forever — you’ll need it every time you log in to file taxes.
Online (recommended). Use the State of New Jersey Online Tax/Employer Registration portal. There is no fee for NJ-REG itself — the only fees are entity formation ($125 for-profit, $75 domestic nonprofit) paid earlier through the NJ Business Formation portal. Processing is immediate for the BRC and Certificate of Authority, both downloadable as PDFs at the end of the session. Save the confirmation number and the PDFs as your proof of filing.
By mail. Print the paper NJ-REG packet, complete it in blue or black ink, and mail it to Client Registration Bureau, NJ Division of Revenue and Enterprise Services, P.O. Box 252, Trenton, NJ 08646-0252. There is no filing fee. Processing time is 4–6 weeks. Send by USPS Certified Mail with Return Receipt; the green card is your proof of filing.
In person. Walk-in service is available at 33 West State Street, 5th Floor, Trenton, NJ 08608, Monday through Friday, 8:30 a.m. to 4:30 p.m. There is no fee. Same-day processing is available if you arrive before 3:00 p.m. The clerk hands you a stamped copy as your proof of filing.
Fax is no longer accepted for NJ-REG as of the most recent revision. Filers who previously used fax must switch to online or mail. For phone help, call DORES at 609-292-9292 (Option 1) as listed on the vendor information page.
What Happens After You File
Within minutes (online) or weeks (mail), you’ll receive your New Jersey Tax ID Number — a 12-digit identifier that begins with your FEIN plus a 3-digit suffix. You will also receive your Business Registration Certificate (BRC), required for any New Jersey state contracting or grant work. If you registered for sales tax in Section G, you’ll also receive a Certificate of Authority that you must display at every place of business and event where you sell, per the NJ Division of Taxation vendor rules.
DORES then sets up your tax accounts behind the scenes. You’ll receive separate welcome letters for each account: Sales and Use Tax (ST-50/ST-51), Employer Withholding (NJ-927), Unemployment Insurance (WR-30), and Corporation Business Tax (CBT-100/CBT-100S) if applicable. Each letter contains a filing schedule and a PIN. You should login at the Sales and Use Tax filing portal within 30 days and create a master account to consolidate your filings.
Annual maintenance kicks in immediately. Every domestic and foreign entity must file an Annual Report with DORES on the last day of the entity’s anniversary month, paying a $75 filing fee. Missing the Annual Report twice in a row leads to administrative dissolution or revocation of authority. Updates to your address, ownership, NAICS, or any other field must flow through the Registration Change and Amendment service, not a new NJ-REG.
Mistakes to Avoid When Filling Out the Form
These are the errors DORES sees most often. Each one delays your BRC, costs money, or both.
- Filing NJ-REG before the Public Records Filing. The system rejects you because there’s no NJ Entity ID yet.
- Wrong NAICS code. Triggers wrong account configuration and missed industry tax credits.
- Mismatched legal name. Even one-character differences vs. the IRS CP 575 letter cause “name mismatch” rejection.
- Backdated begin date. Creates retroactive sales, withholding, and CBT minimum tax obligations and penalties.
- P.O. Box in the business location field. Flags the file as having no physical presence in New Jersey.
- Owner percentages not totaling 100%. Stops Section J processing entirely.
- Skipping the resale certificate box. Means you cannot legally buy goods tax-free for resale.
- Checking “No” to sales tax when you actually sell taxable items. Operating without a Certificate of Authority triggers per-sale penalties.
- Forgetting Section H for S-corp owner-employees. Results in no withholding account and bounced first payroll.
- Skipping Section I Litter Tax. Many small retailers and food sellers owe it and don’t know.
- Wet-ink signing on a paper form with the wrong color. DORES requires blue or black; pencil or red is rejected.
- Bookkeeper signing without POA on file. DORES voids the application as unsigned.
Do’s and Don’ts
The following list distills 30 years of NJ-REG filings into the rules that consistently save filers from rework and penalties.
- Do form your entity first via the NJ Business Formation portal before opening NJ-REG, because NJ-REG requires your Entity ID.
- Do print or screenshot your confirmation number the second the portal shows it, because you’ll need it for every future tax filing.
- Do match your legal name byte-for-byte to your IRS CP 575 letter, because DORES uses exact-match logic.
- Do pick the most specific 6-digit NAICS code, because it controls which tax credits you qualify for.
- Do display your Certificate of Authority at every selling location, because field auditors check.
- Do save the BRC PDF in the cloud, because public-contract bidders need to attach it to every solicitation.
- Don’t use a P.O. Box in Section D’s business location field, because it fails the physical-presence test.
- Don’t backdate Section F’s begin date, because it creates retroactive tax liability.
- Don’t check Amended in Section A on a first-time application, because there’s nothing to amend.
- Don’t treat 1099 contractors as employees in Section H, because misclassification triggers ABC-test audits.
- Don’t skip Section I if you sell paper, food, or soft drinks, because the Litter Tax applies to you.
- Don’t assume federal IRS changes propagate to NJ, because they don’t — you must amend NJ-REG separately.
Pros and Cons of Filing on Your Own vs. With Help
Filing NJ-REG yourself saves money but exposes you to errors that cost more later. Hiring a CPA or attorney costs upfront but reduces rework and audit risk. Below is the honest trade-off.
- Pro of filing solo: No professional fees — NJ-REG is free, and the online portal walks you through the form.
- Pro of filing solo: Faster, because you don’t wait on a third party’s calendar.
- Pro of filing solo: You learn your own tax accounts, which helps with later filings.
- Pro of filing solo: You can iterate quickly if you make a small typo, since the Registration Change service is also free.
- Pro of filing solo: You retain control of confidential ownership data.
- Con of filing solo: You may miss the NAICS or sales tax nuance and pay penalties.
- Pro of professional help: A CPA spots S-corp election issues, public-works flags, and Litter Tax exposures before submission.
- Pro of professional help: Attorneys handle complex foreign-entity nexus and protect against authority-to-do-business fines.
- Pro of professional help: Professionals carry malpractice insurance, so misfilings have a backstop.
- Pro of professional help: They draft and store the M-5008-R Power of Attorney needed for ongoing representation.
- Pro of professional help: They coordinate the Public Records Filing, EIN, and NJ-REG in the right order.
- Con of professional help: Fees range from $250 to $1,200 depending on entity type and complexity.
Filing Online vs. by Mail at a Glance
The choice between online and paper changes timing, fees, and proof of filing. The table below shows where the two channels diverge.
| Filing Method | Key Differences |
|---|---|
| Online via NJ Portal | No fee; instant BRC and Certificate of Authority; downloadable PDFs as proof; available 24/7 |
| Paper by mail | No fee; 4–6 weeks processing; certified mail green card as proof; required for filers without an EIN ready |
FAQs
Is there a fee to file NJ-REG?
No. NJ-REG itself is free. Entity formation through the Public Records Filing carries a $125 fee for for-profit entities and $75 for domestic nonprofit corporations.
Do I need an EIN before filing NJ-REG?
Yes. Corporations, LLCs, LPs, LLPs, and partnerships must have an EIN. Sole proprietors with no employees may use an SSN, but an EIN is recommended.
How long does it take to receive my Business Registration Certificate?
Yes, processing time matters. Online filings produce the BRC immediately as a downloadable PDF. Paper filings take 4–6 weeks via mail.
Can I file NJ-REG before I form my LLC?
No. You must complete the Public Records Filing for the entity first, because NJ-REG requires the 10-digit NJ Business Entity ID issued at formation.
What do I write in Section A if I’m opening a second location?
Yes, you check Application for a new location of an existing registered business in Section A and reference your existing NJ Tax ID in the prompt below.
Do I write my SSN or EIN in Section B?
Yes, if you’re a sole proprietor with no employees, your SSN is allowed. Entities and any business with employees must use the EIN.
What if my owner percentages don’t total 100% in Section J?
No, you cannot submit. The system rejects the form until all member, partner, or shareholder percentages sum to exactly 100%.
Do I need to register for sales tax if I only sell online?
Yes, if you have New Jersey nexus — physical, employee, or economic ($100,000 in sales or 200 transactions per year) — you must register and collect.
Can my accountant sign NJ-REG for me?
No, not without a Form M-5008-R Power of Attorney on file with DORES. Otherwise an owner, partner, or officer must sign personally.
What happens if I file NJ-REG late?
Yes, penalties apply. Foreign LLCs face $200 per partial year of unregistered activity. Foreign corporations and LPs face $200–$1,000 fines plus back taxes and interest.
Do I need to refile NJ-REG every year?
No. NJ-REG is a one-time registration. You only file an Annual Report (with a $75 fee) each year on the last day of your anniversary month.
What if I check the wrong NAICS code?
Yes, you can fix it. Use the Registration Change and Amendment service to update the NAICS code. The change is free.
Is the online NJ-REG the same as the paper version?
Yes, the sections (A through J), field labels, and information requested are identical. The online version simply auto-validates and issues certificates immediately.
Do nonprofits file NJ-REG?
Yes. Nonprofits file NJ-REG, then file Form REG-1E separately to apply for sales tax exemption under N.J.S.A. 54:32B-9.
