How to File a DBA for a Corporation

Confirm the Corporation Is Properly Formed First

Before filing a DBA, make sure your corporation's own filings are current: its Articles of Incorporation are on record with the state, it has an EIN from the IRS, and, in states that require one, its most recent annual report or franchise tax filing is up to date so the corporation is in good standing. A DBA application typically asks for the corporation's exact legal name and state of incorporation, so any mismatch here can delay the filing.

Search for Name Availability

Search your state's, or in states like California, your county's, business name database for the exact DBA name you want, along with close variations. Most agencies reject a name identical or confusingly similar to one already on file, and many also block a name that includes "LLC" or a similar designator that doesn't match the corporation's actual structure. This search covers only that local registry; it isn't a trademark search, so also check the USPTO's trademark database separately if you want to rule out a national conflict.

Complete the Application With the Corporation's Legal Name

The application needs the corporation's exact legal name as filed with the state, its state of incorporation, and the specific DBA name it wants to use. Most states require an authorized officer, commonly the president, secretary, or another listed corporate officer, rather than any employee, to sign the filing on the corporation's behalf, since the signature is certifying the corporation's authorization to use the name.

File With the Correct Agency

Most states that register DBAs for LLCs use the same agency and process for corporations. California's fictitious business name law, and Florida's fictitious name statute, both explicitly list corporations alongside LLCs and partnerships under the same provisions, so a corporation in those states files with the same county clerk (California) or the Division of Corporations (Florida) that an LLC would use, paying the same fee. Confirm your specific state's current fee and agency, since a handful of states handle non-LLC filings differently; Louisiana, for example, routes certain local DBA filings through the parish Clerk of Court separately from its statewide trade name registration.

Pay the Fee and Complete Any Publication

Fees follow the same range as any other entity type in a given state: California's base fee is $10 with counties commonly charging more, Florida charges $50, and Maine charges $125. If your state requires newspaper publication, such as Florida requiring the ad to run before filing, or California requiring publication within 45 days after filing, budget that timeline in alongside the filing itself.

Update Records Once Approved

Once the DBA is on file, bring the approval along with the corporation's EIN and Articles of Incorporation to your bank to add the DBA as an operating name on the corporate account. Update contracts, invoices, and any local business license to reference the DBA alongside the corporation's legal name, and keep a copy of the approved filing with your other corporate records.

Corporate Resolutions Aren't Always Required, but Check

Some states or a corporation's own bylaws may require a board resolution authorizing use of a new DBA before an officer signs the filing, even though the state filing agency itself may not ask for that resolution directly. Check your corporation's bylaws and keep any required resolution in your corporate minute book regardless of whether the state asks for it.

Keep the DBA Filing With Your Other Corporate Records

Store the approved DBA filing alongside your Articles of Incorporation, bylaws, and annual report filings, since banks, auditors, and potential buyers of the business may ask to see the complete set of corporate records together.

A Subsidiary Needs Its Own DBA, Not a Shared One

If a corporation operates through a separate subsidiary corporation, the subsidiary generally needs its own DBA filing under its own legal name; a parent corporation's DBA doesn't automatically extend to a legally separate subsidiary.

Not Legal or Tax Advice

Signature authority, required resolutions, and filing specifics vary by state and by each corporation's own bylaws. Talk to a business attorney about your specific corporate governance requirements before filing.
