An NJ Business Registration Certificate is proof that a business is registered with the New Jersey Division of Revenue. You need one to work as a contractor or subcontractor for the State or other New Jersey public agencies, for casino licensing, and as an unincorporated construction contractor. Most private businesses never need it.
That last line saves a lot of wasted time. The certificate isn't a general business licence, and it isn't something every New Jersey business must hold. This guide uses the Division of Revenue and Enterprise Services page on the certificate, read in October 2026.
Who needs a Business Registration Certificate
| Situation | Certificate needed? |
|---|---|
| Contractor or subcontractor doing business with the State of New Jersey or another public agency | Yes, under N.J.S.A. 52:32-44 |
| Licensure with the Casino Control Commission | Yes |
| Unincorporated construction contractor working in New Jersey | Yes, under Chapter 85, P.L. 2006 |
| Private business selling only to other businesses or consumers | No |
| Nonprofit contracting with a public agency | Not subject to the proof of registration requirement, though it may still need to register for tax |
The 15% exception for small public contracts
Here's the rule most contractors miss. Even on public work, the certificate isn't required when the value of a single contract is less than 15% of the contracting agency's bid threshold, or when the total of your contracts with that agency in a fiscal year stays below 15% of its bid threshold. Bid thresholds are listed by the Division of Purchase and Property under agency information. So a one-off small job for a town may not need it, but a run of small jobs can tip you over.
Two purposes, one certificate
- Proof of valid business registration for public contracting.
- Proof of registration for unincorporated construction contractors, under the rules defined in N.J.S.A. 54A:7-1.2.
How to get the certificate, step by step
- Check the online business registration inquiry to see if your business is already registered.
- If you're a registered vendor but never received the certificate, download it online.
- If you aren't registered and need the certificate, complete Form NJ-REG.
- If you're a corporation, LLC, limited partnership or LLP, first get legal authority to operate in New Jersey, usually by filing a Certificate of Incorporation or Formation with the Division.
- If you're an individual or an unincorporated construction contractor with no business tax or employer obligations, you can use the shorter Form REG-A instead of NJ-REG.
One catch on that last step. If you've created a business entity, such as an LLC, you can't use REG-A, even if you're a one-person business.
Out-of-state companies and casino suppliers
If your company is formed outside New Jersey but contracts with public agencies there, or has tax nexus in the state, you must get legal authority to operate in New Jersey before you submit Form NJ-REG. That usually means filing with the Division first, then registering. Casino suppliers are the other group that often needs the certificate, because proof of registration is required for licensure with the Casino Control Commission. If you're quoting for work in that industry, sort the certificate out before the paperwork reaches the regulator.
REG-A or NJ-REG?
| Form | Who uses it |
|---|---|
| NJ-REG | Most businesses, including corporations, LLCs and partnerships, and anyone with tax or employer obligations |
| REG-A | Individuals or unincorporated construction contractors with no business tax or employer obligations |
What the certificate isn't
People mix this up with other New Jersey paperwork. The Business Registration Certificate isn't your company formation document, it isn't a sales tax certificate, and it isn't a licence to trade. It's proof that the Division of Revenue has your business on its register, used by public buyers and the casino regulator. You can be fully registered and trading in New Jersey without ever downloading it.
Before you bid on public work
- Check whether the contract, or your total contracts with that agency this fiscal year, crosses 15% of its bid threshold.
- If it does, look yourself up on the online registration inquiry.
- Download the certificate if you're registered, or file NJ-REG or REG-A if you aren't.
- Keep a copy with your bid documents, and check that every subcontractor on the job has one too, because the rule covers subcontractors as well.
Getting help
The Division's Customer Contact Center helps with registration on 609.292.9292. You can submit Form NJ-REG online, but the Division asks you to read its notes first, because an entity that has tax nexus in New Jersey or contracts with public agencies must already have legal authority to operate in the state.
Common mistakes
- Assuming every New Jersey business needs the certificate.
- Using REG-A when the business is an LLC.
- Filing NJ-REG before an out-of-state company has authority to operate in New Jersey.
- Ignoring the 15% rule and losing a public contract on paperwork, or assuming it applies after several small contracts in one year.
If you're forming the company first, my guide to starting an LLC walks through it, and my certificate of good standing guide covers another document public buyers often ask for.

My verdict
If you sell to the public sector in New Jersey, work in casino services or run an unincorporated construction business, get the certificate before you bid. If you don't, you probably don't need one. Check the registration inquiry first, because many registered vendors already qualify and only need to download it.
