How to Start a Business in Trenton

Trenton is the state capital and a city working hard to grow its small-business base, and opening a business here follows the same path as anywhere in New Jersey, with a few local steps on top. Here is how to go from an idea to open for business.

Step 1: Choose your structure

Your first decision is what kind of business entity to be. Only an LLC, corporation (C-Corp or S-Corp), limited partnership, or limited liability partnership forms a legal entity with the state. A sole proprietor or general partnership does not form an entity, though if you want to operate under a name other than your own, you can register a trade name with the Mercer County Clerk. The structure you pick affects your taxes, your paperwork, and your personal liability, so it is worth a conversation with an accountant.

Step 2: Name it and get an EIN

Check that your business name is available through the state, then get an Employer Identification Number (EIN) from the IRS. The EIN is free, you can get it online at irs.gov, and you will need it to file taxes, hire employees, and open a business bank account.

Step 3: Register with New Jersey

New Jersey runs a single portal, Business.NJ.gov, that walks you through formation and registration. If you are forming an entity, you file your formation documents with the Division of Revenue and Enterprise Services; the filing fee is $125 for most businesses. Then, and this part applies to everyone, you must file Form NJ-REG to register for state tax and employer purposes. Registration itself is free, and it should be done within 60 days of forming your business. The state’s Division of Revenue page lays out the steps by business type.

Step 4: Handle local licenses and zoning

State registration is not the finish line. Depending on your industry, the City of Trenton may require a mercantile license or specific permits, and any physical location has to comply with city zoning. Confirm the requirements with the city before you sign a lease or open your doors. Because those rules are set locally, it helps to understand how city government works; our guide to following Trenton City Council shows where ordinances get made. Once you are operating from a property, you will also want to understand how New Jersey property taxes work, since they will be part of your cost of doing business.

Step 5: Get local help, and it is free

You do not have to figure this out alone. The New Jersey Small Business Development Center, SCORE, and the economic-development nonprofit Greater Trenton all offer free guidance to new business owners. And if a city service issue comes up as you set up, our guide on how to report a problem to the city points you to the right department.

Trenton’s central location, between New York and Philadelphia and served by rail, is a real asset for a new business, as we cover in getting around Trenton. More coverage is in our Business section.
