Forming an LLC or corporation creates the company. It does not register it for taxes. In New Jersey that is a separate step: Form NJ-REG, the state’s tax and employer registration. NJ-REG sets up your New Jersey taxpayer account, your sales tax permit if you sell taxable goods or services, and your payroll accounts if you have employees. Once it is filed, you can download your NJ business registration certificate.
New Jersey’s Getting Registered page says all individuals and companies doing business in the state must be registered, and the state’s Starting a Business in New Jersey guide asks new businesses to register at least 15 business days before opening. In practice, many owners only discover NJ-REG when a supplier asks for a resale certificate, a public agency asks for their BRC, or the first payroll is due.
We file NJ-REG as part of our business formation services, right after the company is formed and the EIN is issued, or on its own for a business that is already running.
We prepare and file Form NJ-REG online with the right business activity, tax types and start dates. The answers decide which returns New Jersey will expect from you, so a careless registration can leave you with filing obligations you don’t need or missing ones you do. You receive a 12-digit New Jersey taxpayer ID that follows your federal EIN.
In general, every New Jersey business selling taxable goods or services must collect and remit New Jersey sales tax. When NJ-REG shows that you will collect sales tax, New Jersey issues a Certificate of Authority for Sales Tax, your seller permit. It lets you collect sales tax and issue and accept exemption certificates, and it must be displayed at your place of business. We set up your sales tax filing frequency and add the returns to your calendar. For where NJ-REG fits among the other start-up steps, see how to start an LLC in New Jersey.
Every business that operates in New Jersey registers through NJ-REG. The certificate itself, often called the BRC, is required in specific cases listed on the Division of Revenue’s Business Registration Certificate page:
Companies formed outside New Jersey, for example a Delaware or Wyoming LLC, must have authority to operate in New Jersey before filing NJ-REG.
If your business adds a new tax type, changes its name, address or officers, or changes its activity, the registration must be updated. A change of ownership, a merger or a new location calls for a new NJ-REG. We handle those filings when they come up.
Business registration sits in the middle of a short chain. First, form your New Jersey LLC or other entity and get the EIN. Then register through NJ-REG. After that, the recurring work begins: NJ sales tax returns, payroll filings if you have employees, the yearly NJ annual report, and books that hold everything together.
Most of our registration clients are small businesses in New Jersey such as shops, restaurants and contractors, and many keep us on for monthly bookkeeping once the registration is done.
