Using a name other than your legal business name? Here’s what a DBA (Doing Business As) actually means in New York.
If you’ve chosen a business name that’s different from your personal name or your company’s legal name, you may need to file a DBA, also known in New York as an assumed name. A DBA does not create a new business entity—it simply allows an existing person or entity to legally operate under a different name.
For example:
- John Smith wants to operate as Empire Home Inspections → likely needs a DBA.
- Hudson Property Group LLC wants to market its renovation division as Hudson Kitchens → the LLC may need to file an assumed name.
Understanding the difference between forming a business and registering a DBA can save you from filing the wrong paperwork.
What is a DBA?
A DBA stands for “Doing Business As.” In New York, the official term is assumed name. It allows a business to conduct business, advertise, accept payments, and build a brand using a name other than its legal name.
A DBA is commonly used when:
- A sole proprietor wants a professional business name instead of their personal name.
- An LLC launches a new product or service under a different brand.
- A corporation operates multiple brands without creating separate companies.
Importantly, a DBA is not the same thing as forming an LLC or corporation.
Do You Need A DBA?
The answer depends on your business structure.
| Business type | Need a DBA? | Where to file |
|---|---|---|
| Sole proprietor using only your own legal name | No | No filing |
| Sole proprietor using a trade name | Yes | County Clerk |
| General partnership using a business name | Usually yes | County Clerk |
| LLC using its exact legal name | No | No filing |
| LLC using another brand name | Yes | NY Department of State |
| Corporation using another brand name | Yes | NY Department of State |
New York separates DBA filings based on the type of business. Sole proprietorships and general partnerships file locally with the county clerk, while LLCs, corporations, and limited partnerships file a Certificate of Assumed Name with the New York Department of State.
County filing vs. state filing in New York
This is one of the most common points of confusion.
Sole proprietors and general partnerships
If you’re operating as an individual or general partnership under a trade name, you generally file a Business Certificate with the county clerk in the county where your business operates. In New York City, each borough has its own county clerk.
Example: Maria Lopez starts a catering business called Golden Table Catering in Brooklyn. Because she’s a sole proprietor using a trade name, she would file with the Kings County Clerk.
LLCs and corporations
If you’ve already formed an LLC or corporation and want to operate under another name, you file a Certificate of Assumed Name with the New York Department of State—not the county clerk. The filing identifies your legal entity, the assumed name, and the counties where you’ll conduct business.
Example: ABC Construction LLC wants to advertise its roofing division as Empire Roofing. The LLC remains the legal entity; the assumed name simply authorizes the alternate brand.
DBA vs. LLC: What’s the difference?
Many new business owners mistakenly believe a DBA creates a company. It doesn’t.
| DBA (Assumed Name) | LLC or Corporation |
|---|---|
| Alternate business name | Separate legal entity |
| Does not create liability protection | Can provide liability protection |
| Does not change ownership | Establishes the legal business |
| Used for branding and operating under another name | Used to legally organize the business |
If your goal is protecting personal assets, forming an LLC or corporation—not filing a DBA—is typically the relevant legal step. A DBA only changes the name under which business is conducted.
What information is included in an assumed name filing?
While the required form differs by entity type, New York filings generally identify:
- The legal name of the business or owner
- The assumed (DBA) name
- The principal business address
- The county or counties where business will be conducted
- The authorized signer for the business entity
For LLCs and corporations, the assumed name becomes effective upon filing with the Department of State.
Choosing the right filing
A DBA can be an excellent branding tool, but it’s important to file the correct document with the correct office. Whether you’re starting a sole proprietorship, expanding an LLC with a new brand, or operating multiple business names, the filing requirements depend on your legal structure—not simply the name you want to use.
If you’re unsure whether your business should file an assumed name, form a new entity, or take another legal step, speaking with a New York business attorney can help ensure your filing matches your business goals.
