How to File a DBA in New Jersey: Alternate and Trade Names

To file a DBA in New Jersey, you first need to know which of three filings actually applies to your business, because New Jersey does not use one universal “doing business as” form. LLCs, corporations, and limited partnerships file an alternate name with the state Division of Revenue and Enterprise Services. Sole proprietors and general partnerships file a trade name with the county clerk in each county where they operate. The label DBA itself is reserved for out-of-state businesses that need a different operating name in New Jersey because their home-state name is already taken here.¹²

Pick the wrong path and you get turned away. An LLC owner cannot file at the county clerk’s office, and a sole proprietor cannot file with the state.

Which Filing Applies to You

LLC, profit corporation, nonprofit corporation, or limited partnership → alternate name, filed with the state.
Sole proprietor or general partnership operating under any name other than the owners’ personal names → trade name, filed with the county clerk.
Business formed in another state whose legal name is already taken in New Jersey → DBA, filed as part of your foreign entity authorization.

Check Name Availability First

New Jersey requires business entity names to be distinguishable from other active registrations, so a duplicate or near-duplicate alternate name will be rejected.³

If you are filing at the state level, run your proposed name through the Business Name Availability search operated by the Division of Revenue and Enterprise Services.⁴ Sole proprietors and general partnerships should call or visit the county clerk’s office directly. Trade names live in county records and do not appear in the state database.

Filing an Alternate Name (LLCs, Corporations, Limited Partnerships)

Use Form C-150G, Registration of Alternate Name, filed with the Division of Revenue and Enterprise Services. You can submit online through the state’s business amendments portal, by mail, or by fax.¹

The form asks for:

Your entity’s legal name as registered with the state.
Your New Jersey 10-digit business identification number.
State and date of formation (and, for foreign entities, date of New Jersey authorization).
The proposed alternate name.
A brief description of the business activity you will conduct under that name.
A prior-use disclosure: whether you have already used the name in New Jersey, and if so, since when.

The filing fee is $50.⁵ The prior-use question has money attached to it. If you have been operating under the name before registering, you owe an additional $50 for each year of unauthorized use, and a partial year counts as a full year.¹ Three and a half years of unregistered use means $50 plus $200 in back fees.

Filing a Trade Name (Sole Proprietors and General Partnerships)

If you run a sole proprietorship or general partnership and want to operate under anything other than the owners’ personal names, register a trade name with the county clerk in every New Jersey county where you conduct business.⁶ This is a county filing, not a state filing.

You will generally need:

The proposed trade name.
The full legal names and residential addresses of all owners.
The business address.
Signatures from all owners, usually in front of a notary or attorney.

Some county offices offer notary services on-site for a small extra charge. Filing fees vary by county but tend to run around $50. County processing is slower than the state’s online portal, so plan on at least a couple of weeks.

Out-of-State Businesses: The True DBA

An out-of-state business only needs a New Jersey DBA when its home-state name is already taken by an active New Jersey entity. First, check whether your exact legal name is available here. If it is, you register to do business in New Jersey under that name and you are done. If it is not, you search for an available DBA name and register it as part of your foreign entity authorization filing.² You do not pick a DBA proactively.

What Happens If You Skip Registration

Operating under an unregistered name has consequences beyond the back-fee math. The most serious one: your business may lose the ability to bring lawsuits in New Jersey courts for any transactions conducted under the unregistered name. You can still defend yourself against suits, but you cannot initiate them until the proper certificate is on file.⁷

For LLCs, failure to register within 60 days of being notified of the obligation carries a state penalty of $200 to $500. Filing a certificate with a false statement about when you started using the name, to reduce the back fees, carries the same $200 to $500 penalty.⁷ Corporations face a parallel structure: the regular filing fee multiplied by the number of years of unauthorized use.⁸

Register before you start using the name. Catching up later is more expensive, and it can block you from enforcing contracts in court.

Renewing an Alternate Name

Alternate name registrations for LLCs, corporations, and limited partnerships are valid for five years from the filing date.¹ The state sends a reminder between one and four months before expiration, but do not rely on it. Renew within the 90-day window before expiration using Form C-150R, Renewal of Registration of Alternate Name, online or by mail.⁹

Renewal fees:

Profit corporations: $25.
Nonprofit corporations, LLCs, and limited partnerships: $50.

Miss the deadline and keep using the name, and the $50-per-year back-use penalty restarts.

Trade names filed at the county level do not follow the same five-year cycle. Ask your county clerk about renewal or re-filing rules, which vary by county.

Amending or Canceling Your Registration

If your business address, ownership, or other details change, update the filing. State-level alternate names can be amended through the Division of Revenue’s business amendments portal or by submitting an updated Form C-150G. For county-level trade names, contact the county clerk where you registered; procedures differ.

When you stop using the name, file a termination certificate rather than letting the registration sit. For profit corporations, the form is the Certificate of Termination of Corporate Alternate Name, with a $75 fee.¹⁰ LLCs and limited partnerships should contact the Division of Revenue for the applicable termination form and fee; the $75 corporate form does not cover them. Sole proprietors and general partnerships cancel a trade name by filing a dissolution of the business name certificate with their county clerk, with fees set by the county.

A DBA Is Not Trademark Protection

Registering an alternate name or trade name gives you the right to operate under the name. It does not stop anyone else from using the same or a similar name for their own business. If you want exclusive rights to the name, that is a separate process: a New Jersey state trademark protects the name within the state, and a federal trademark through the U.S. Patent and Trademark Office protects it nationwide. Different applications, different fees, different legal standards. The DBA tells the government who you are. A trademark tells competitors to stay away.
