DBA Registration Form

A DBA Registration Form in the United States submits the applicant's details to the relevant authority for the approval it seeks.

The legal requirement to register fictitious business names derives from state statutes. California Business and Professions Code §§ 17900-17930 govern fictitious business name registration in California, requiring county-level filing and newspaper publication for four consecutive weeks. Texas Business & Commerce Code §§ 71.001-71.209 govern assumed name registration in Texas, requiring filing with the county clerk in each county where the business maintains a registered office or principal place of business, with additional state-level filing for LLCs, corporations, and limited partnerships. New York General Business Law §§ 130-135 require sole proprietors and general partnerships to file certificates of assumed name with the county clerk, while corporations, LLCs, and limited partnerships file with the New York Department of State. Florida Statutes § 865.09 requires filing with the Florida Department of State, Division of Corporations, and newspaper publication.

A DBA Registration Form is distinct from several other business name filings that are sometimes confused with it. A corporate name reservation — filed with a state secretary of state — reserves the right to use a specific name for an entity being formed, but does not register a fictitious name for existing operations. A trademark registration — filed with the US Patent and Trademark Office (USPTO) under the Lanham Act (15 U.S.C. § 1051) — provides nationwide exclusive rights in a mark for specific goods and services, but does not substitute for the state-level DBA filing required by state law. A state entity name registration — the name under which an LLC or corporation is formed with the secretary of state — is the entity's legal name, not a DBA; the DBA is any additional name used in commerce that differs from the registered entity name.

DBA registrations are also called fictitious business names, assumed names, trade name certificates, or "doing business as" filings depending on the state. The IRS recognizes DBA names for federal tax purposes — a business may use its DBA name on invoices and in correspondence while filing taxes under its legal entity name and Employer Identification Number (EIN). State tax authorities, including the California Department of Tax and Fee Administration (CDTFA), the Texas Comptroller of Public Accounts, and the New York Department of Taxation and Finance, similarly recognize DBA names for sales tax permit and business license purposes.

A US DBA Registration Form is needed whenever a person or business entity conducts business under a name that differs from its legal name, in any US state that requires fictitious business name registration — which includes all 50 states, though the specific requirements and filing locations vary.

A sole proprietor whose legal name is John Smith and who operates a landscaping business under the name "Green Horizon Landscaping" must file a DBA in their state and county before using that business name in commerce, opening a bank account in the business name, or entering into contracts under the business name. Without the DBA filing, California Business and Professions Code § 17918 prohibits the sole proprietor from maintaining a lawsuit in California courts arising from transactions conducted under the unregistered name.

An LLC or corporation that wants to operate under a name other than its registered entity name — for example, "Tech Solutions LLC" operating a consumer-facing service under "QuickFix Tech" — must file a DBA in each state where it conducts business under the assumed name. Texas requires this filing with both the county clerk (for each county of operation) and the Texas Secretary of State. Delaware-registered entities operating DBAs in New York must register with the New York Department of State.

Franchisees operating under a franchisor's brand name — which is typically not the franchisee's legal entity name — often need DBA filings to operate legally under the franchise brand in their local market. For example, an LLC formed as "Johnson Family Restaurants LLC" operating a franchise under a national brand name must file a DBA in the applicable state.

Professional service providers — attorneys, physicians, accountants, and engineers in California, New York, Texas, and other states — who operate professional corporations or LLCs and wish to use a DBA for marketing purposes must confirm that their state's professional licensing board permits the use of assumed names and that any DBA is not misleading to the public. California Business and Professions Code § 17918.5 provides specific rules for professional corporations.

A DBA is also necessary when a business changes its operating name without dissolving and reforming the legal entity — a common scenario for businesses rebranding or expanding into new product lines. Rather than forming a new entity for each product line, many businesses file multiple DBAs under a single legal entity, reducing administrative complexity while maintaining separate brand identities.

A properly completed US DBA Registration Form must contain specific information required by the applicable state statute. While forms vary by state and county, the following elements appear in virtually all jurisdictions.

The fictitious business name section states the exact trade name or assumed name being registered, spelled exactly as it will appear in commerce — including punctuation, capitalization, and any stylized elements. Many state offices reject filings with names that are deceptively similar to already-registered names, and the registrant should search existing registrations at the state secretary of state's online business name database before filing. The California Secretary of State's business search portal, the Texas Secretary of State's SOSDirect system, and the New York Division of Corporations entity search are the standard starting points for these searches.

The registrant identity section identifies who is registering the DBA. For sole proprietors, this is the individual owner's full legal name, home address, and in many states, date of birth. For general partnerships, it is the full legal names and addresses of all partners. For LLCs and corporations, it is the entity's full legal name as registered with the state, the entity's state of formation, the registration/charter number, and the name and title of the authorized signatory executing the filing.

The principal place of business section states the physical street address where the business principally operates under the DBA name — not a P.O. Box, in most states. For businesses with multiple locations, the principal location is typically used. California requires separate registration in each county where the business operates, making the principal place of business address determinative of the correct filing county.

The commencement of business section, required in some states, states the date the registrant began or intends to begin operating under the fictitious name. California requires this date on the Fictitious Business Name Statement.

The notarization or acknowledgment section, required in many states, requires the registrant's signature to be notarized or acknowledged before an authorized official. The notary must verify the signatory's identity and witness their signature. Some states, including Florida and Colorado, accept online filing without notarization.

The publication requirement — required in California (4 weeks in a local newspaper of general circulation), New York (6 weeks for New York City counties, 4 weeks elsewhere), and several other states — requires proof of publication (an affidavit of publication from the newspaper) to be filed with the county clerk to complete the registration. Failure to complete the publication requirement leaves the registration incomplete and may void the filing.
