How to File a DBA (Doing Business As)

A DBA (Doing Business As) allows you to operate your business under a name different from your legal name or your LLC's registered name. Sole proprietors need a DBA to do business under any name other than their full personal name. LLCs and corporations need a DBA to operate under a trade name that differs from the entity name on file with the state. Filing costs $10 to $100 in most jurisdictions, and the process takes anywhere from same-day to a few weeks.

When You Need a DBA

A DBA is required in two common situations. First, if you are a sole proprietor and want to operate under a business name rather than your personal name. Jane Smith who sells handmade candles under the name "Meadow Light Candles" needs a DBA because "Meadow Light Candles" is not her legal name. Without the DBA, she cannot open a bank account, accept checks, or sign contracts in that business name. She would need to conduct all business as "Jane Smith," which makes the business look less professional and ties every transaction to her personal identity.

Second, if your LLC or corporation wants to use a trade name different from its registered legal name. "Smith Holdings LLC" might want to operate a candle shop under the name "Meadow Light Candles" and a soap line under the name "Fresh Creek Soaps." A DBA for each trade name allows a single LLC to operate multiple brands without forming separate entities for each one. This is common for ecommerce sellers who run multiple Shopify stores or sell different product lines under different brand identities, all owned by a single LLC.

You do not need a DBA if you do business under your full legal name as a sole proprietor, if your LLC does business under its registered LLC name (including the "LLC" designator), or if your corporation does business under its registered corporate name. Adding "LLC" or "Inc." to your business name in marketing materials and on your website is expected and does not require a DBA. Dropping the "LLC" from your registered name in customer-facing contexts technically requires a DBA in most states, though enforcement varies.

DBA Filing Process

Step 1: Determine where to file.
DBA filing requirements vary by state. Some states require filing at the county level (with the county clerk or recorder's office), some require filing at the state level (with the Secretary of State), and some require filing at both levels. In Texas, you file with the county clerk in the county where you do business. In California, you file with the county clerk where your principal place of business is located. In Florida, you file with the state Division of Corporations online. Check your state's requirements first, since filing in the wrong office means your DBA is not legally registered.
Step 2: Search for name availability.
Before filing, search the relevant database (county or state) to confirm your DBA name is not already taken. This is a separate search from the business entity name search you do when forming an LLC. A DBA name can be the same as an existing LLC name in some states because the DBA is linked to a specific owner, not a standalone entity. However, if the name is already registered as a DBA by another business in your county or state, you cannot use it. Also check the USPTO trademark database to avoid infringing on a registered trademark, since a DBA registration does not grant trademark rights.
Step 3: Complete and submit the DBA form.
The DBA application (often called a "fictitious business name statement," "assumed name certificate," or "trade name registration" depending on the state) asks for your legal name, the business name you want to use, your business address, the type of business, and the names of all owners. For an LLC filing a DBA, the LLC is listed as the owner, not the individual members. The filing fee ranges from $10 to $100, with most counties charging $20 to $50. Some states allow online filing; others require in-person or mail filing. Bring a photo ID if filing in person.
Step 4: Publish the DBA if your state requires it.
Several states, including California, Florida, Georgia, Illinois, Nebraska, and Pennsylvania, require you to publish your DBA filing in a local newspaper for a specified period, usually once a week for four consecutive weeks. The newspaper must be a "newspaper of general circulation" in the county where you filed. Publication costs range from $30 to $200 depending on the newspaper's rates and your county. After publication, file the proof of publication (an affidavit from the newspaper) with the filing office. Failure to complete the publication requirement can void your DBA registration or prevent you from using the DBA in legal proceedings.
Step 5: Use your DBA for business operations.
Once your DBA is filed (and published, if required), bring the DBA certificate to your bank to open a business account under the trade name or add the DBA name to an existing account. You can now accept payments, write checks, and sign contracts using the DBA name. Include the DBA on your business licenses, your website, your marketing materials, and anywhere else you represent your business to the public. If you file tax returns, your DBA name goes on the "trade name" or "DBA" line, while your legal name (or LLC name) goes on the "legal name" line.

DBA vs LLC: Understanding the Difference

A common misconception is that a DBA provides the same protections as an LLC. It does not. A DBA is a name registration, not a legal entity. It gives you permission to use a business name, but it creates no liability protection, no tax entity, and no legal separation between you and the business. A sole proprietor with a DBA is still a sole proprietor, with all personal assets exposed to business liabilities. If you want liability protection, you need to form an LLC or corporation. You can then file a DBA under the LLC if you want to operate under a different name.

Many new business owners file a DBA thinking it "registers" their business and provides some form of official business status. It does not. A DBA simply tells the public who is behind a business name. If "Meadow Light Candles" is sued and has only a DBA (no LLC), the suit is against Jane Smith personally. If "Meadow Light Candles" is a DBA of "Smith Holdings LLC," the suit is against the LLC, and Jane's personal assets are protected.

DBA Renewal and Expiration

DBA registrations expire in most states after a set period, typically five years. Some states (California, for example) require renewal by filing a new fictitious business name statement before the expiration date. The renewal process is essentially the same as the original filing: complete the form, pay the fee, and publish if required. If you let your DBA expire without renewing, you lose the right to use that business name, and someone else could register it.

If you stop using a DBA name, file a withdrawal or abandonment notice with the same office where you filed the original DBA. This formally releases the name and prevents any legal complications from having a registered business name that you no longer use. If you close your business entirely, canceling all DBAs should be part of your dissolution checklist.

Multiple DBAs

A single LLC or individual can hold multiple DBAs simultaneously. An ecommerce seller who operates three different Shopify stores under three different brand names might have one LLC with three DBAs. Each DBA requires a separate filing and fee, but all business operations are conducted through the single LLC. This is more efficient and less expensive than forming three separate LLCs, while still allowing each brand to have its own name, bank account, and public identity.

When operating multiple DBAs under one LLC, keep clear financial records for each brand. Even though they all flow through the same LLC for tax purposes, tracking revenue and expenses by brand lets you know which operations are profitable and which are not. Your accounting software can typically handle this with class tracking or department codes, so each brand's financials are visible without maintaining separate entities.
