Choosing the right business name is more than just a branding decision; it’s a legal requirement that influences how your company operates, registers, and pays taxes. Whether starting your first business or managing multiple brands under one entity, understanding the difference between a trade name, a DBA, and your legal name helps you stay compliant and protected.
What is a trade name?
A trade name is the public-facing name a business uses to identify itself in the marketplace. It may also be called an assumed name, fictitious name, or “doing business as” (DBA) name. In simplest terms, a trade name is any name that differs from the entity’s legal or ‘true name.’
For example, a company officially registered as “Book Sellers LLC” might run its stores and website using the trade name “Children’s Book Depot.” The trade name appears on storefronts, business cards, and marketing materials, reflecting how the business presents itself publicly, even if it differs from the registered legal name.
Trade names enable businesses to build a recognizable brand without establishing a separate legal entity. Nonetheless, simply using a trade name does not provide exclusive rights. To establish exclusive rights to a name, a trademark registration can be filed.
What is a DBA?
You need to register a business certificate if your business operates under a name different from its legal name. The “legal name” is the official name used when registering the business or, for sole proprietors, the owner’s personal legal name. A DBA (“Doing Business As”) is the formal registration that connects a trade name to its legal owner or entity. This registration publicly identifies who is behind the business name.
Each state calls this filing something different, but the intent is the same: to disclose ownership and ensure transparency. Businesses use DBAs to:
- Brand new products or services under one entity
- Market with more flexibility
- Protect privacy (especially for sole proprietors)
- Avoid the cost of forming multiple entities
Although it allows businesses to operate under new names, a DBA doesn’t provide legal protection like a trademark, or new business entity formation does.
What is a legal name?
A legal name is the name officially registered with the state or IRS. For individuals, it’s their personal name. The name shown on incorporation or formation documents is used on tax forms, contracts, and other official records for businesses. For instance, A corporation registered as Lucy’s Food Emporium LLC could operate a DBA called Lucy’s Sip and Read Coffee Shop. Your legal name identifies the formal business entity, while trade names and DBAs help present your brand to the market.
What is a trademark?
A trademark can protect the name of your business, goods, and services nationally. Trademarks prevent others in the same (or similar) industry in the United States from using your trademarked names. For example, if you were an electronics company and wanted to call your business Springfield Electronic Accessories and one of your products Screen Cover 5000, trademarking those names would prevent other electronics businesses or similar products from using those same names.
Businesses in every state are subject to trademark infringement lawsuits, which can prove costly. That’s why you should check your prospective business, product, and service names against the official trademark database, maintained by the United States Patent and Trademark Office.
Is there a difference between a trade name and a DBA?
“DBA” and “Trade Name” are often used interchangeably, but can have specific meanings depending on the jurisdiction. The terminology can be confusing because different terms may indicate “elective” DBAs versus “forced” DBAs. A “forced” DBA refers to a name registered by an entity in a foreign jurisdiction when its legal name cannot be used there. Other terms for DBAs and trade names include:
- Assumed name
- Elected name
- Fictitious name
Recent changes to Delaware DBAs
Delaware’s House Bill 40, signed February 7, 2025, moves trade name (DBA) registration from a county-based system to a new, statewide online process run by the Delaware Division of Revenue. This change is designed to simplify filings. However, anyone with an existing county-level trade name must re-register under the new system, potentially creating uncertainty for current name holders as the transition takes effect in early 2026. (LEGIS.DELAWARE.GOV)
Starting February 2, 2026, Delaware will move all trade name registrations online, using the Delaware One Stop system. This new approach means you’ll no longer need to file papers or visit multiple county offices—everything is done in one place, and notarization isn’t required. Here are some FAQs from revenue.delaware.gov; click the link to learn more.
What documentation is required to register a DBA in Delaware?
To register a DBA in Delaware, you need to provide the legal name and address of the entity, the proposed trade name, names and addresses of ownership, date of formation, and nature of business. Additionally, any LLC or Corporation entity that is not actively transacting business in Delaware will be required to provide a Certificate of Good Standing from the Delaware Division of Corporations and may be required to provide other additional documentation.
What determines an owner needing to provide name and address for a DBA?
Ownership is defined as “Officers, Directors, or shareholders with over 10% of equity”. This is consistent with the Division of Revenue definition for other License tax types.
What changes does the online process bring to Delaware’s DBA application?
The required fields for the DBA application will remain the same as they were with the Courts. DBA registration is now available online and is managed statewide rather than by individual counties. The process also now requires a business license in Delaware.
How much does DBA registration cost?
The fee remains $25, but the DBA is now registered statewide, eliminating the need to pay multiple fees per county.
Is notarization required for trade name applications?
Notarization is no longer required as of February 2, 2026. All applications will be processed online.
Do trade names need to be renewed?
No, trade names in Delaware do not have a regular expiration and do not require renewal as long as they are used by a business with an active business license or trade name only license. If a license is not maintained for three or more years, the Trade Name will revert to the available pool, and the business will be notified.
Trade Name, DBA, and Assumed Name Requirements Nationwide
DBA rules differ significantly by state, so checking the specific requirements before choosing a business name is essential. For example, Florida requires you to renew your registration every five years. In Texas, filings are handled through local county offices. California mandates publishing a notice in the newspaper, while some states simplify the process by only requiring paperwork and a fee. Please get in touch with us for detailed information about your state.
Specific industries also face unique hurdles. Real estate investors might have to file separate DBAs for each property they manage. If you’re in financial services, you may need additional paperwork to verify business ownership and meet extra legal standards.
