Business Trade Names

After opening a Certificate of Trade Name with your County Clerk, you still have a few steps to go to ensure your business is in compliance with State laws. Registering your business with the state is the next step.

ALL new businesses must register with the State of New Jersey for tax and employer purposes.   You must file Form NJ-REG to be registered for tax and employer purposes*. Online registration is available at the Division of Revenue’s website: or paper forms are also available.
* unincorporated construction contractors performing work in NJ also must apply for a Business Registration Certificate.

Filing Form NJ-REG ensures that your business is registered under the correct tax identification number and that you will receive the proper returns and notices. Normally, you will use your federal identification number (FEIN) as the New Jersey tax identification number. A business with employees must obtain a FEIN. If you do not have a federal identification number for your business, you may apply for one as you fill out the online NJ-REG or you may apply directly to the IRS online. A sole proprietorship or partnership can use the social security number of the owner if there are no employees. Once you have registered, your business will receive forms, returns, instructions, certificates and other information required for on-going compliance with New Jersey State taxes. Many of the filings for the business will be able to be completed online.

The NJ-REG must be filed within 60 days of filing the new business.
