Introduction
Filing a DBA — short for "Doing Business As" — lets you run your business under a name that's different from your registered legal name. The process takes 7 steps: find your state's filing agency, check name availability, gather your information, file your forms, pay the required fee, publish notice if your state requires it, and keep your registration current.
What is a DBA?
A DBA — "Doing Business As" — is a registered name that lets a business operate under a name other than its legal name. Depending on your state, you may see it called a fictitious business name, assumed name, or trade name. The goal is the same in every state: it gives you the legal right to use that name in business transactions.
A DBA doesn't create a new legal entity. It's a name registration, not a business formation. If you're a sole proprietor, you're still personally responsible for the business. If you're an LLC or corporation, your existing entity structure stays in place — the DBA just adds a name you can use publicly.
Who needs a DBA?
Not every business needs a DBA, but there are several situations where filing one makes sense. Sole proprietors and general partnerships are the most common filers — if you're running a business under your own name, a DBA lets you use a distinct business name without forming a separate entity.
LLCs and corporations file DBAs when they want to operate under a name that differs from their registered entity name — for example, when expanding into a new market or launching a second brand. An LLC must be formed with the state before it can file a DBA for an additional trade name.
A DBA is also required in most states if you want to open a business bank account under a name other than your legal name. Banks typically ask for a certified copy of your DBA registration before they'll set up the account.
How to file a DBA online
Filing a DBA online follows the same general path in most states, though the specific agency, forms, and fees vary by location. Here's how the process works from start to finish.
Step 1: Find your state's filing agency. DBA filings are handled at the state or local level depending on where you're based. Some states process DBAs through the Secretary of State's office. Others require you to file at the county clerk's office — and if you're expanding into a new location, you may need to file in that county or state separately. Check your state's official business portal to confirm where your filing goes.
Step 2: Check name availability. Your DBA name can't already be in use by another business in your jurisdiction. Most states have a free name search tool on their business portal. Check your state's naming rules at the same time — some states restrict certain words or require specific language for certain business types.
Step 3: Gather your information. Before you file, have the following ready: your legal business name, your business address, your entity type (sole proprietor, LLC, corporation, etc.), and the DBA name you want to register. LLCs and corporations will also need their state registration number.
Step 4: File your forms. Most states let you file a DBA online through their business portal. Some jurisdictions — particularly those that process DBAs at the county or city level — still require paper filings or in-person submissions. If online filing isn't available in your area, check whether a third-party filing service can handle the paperwork on your behalf.
Step 5: Pay the filing fee. Every state charges a fee to register a DBA. Fees vary widely — from under $20 in some counties to over $100 in others — and may differ depending on whether you file at the state or local level. Pay the fee when you submit your forms.
Step 6: Publish a notice if required. Some states require you to publish a notice of your DBA in a local newspaper for a set number of weeks after filing. This is most common in California and New York. Check your state's requirements before assuming this step doesn't apply to you.
Step 7: Track your renewal date. Most DBA registrations expire after a set period — commonly 5 years, though it varies by state. Mark your renewal date when you file. If your DBA lapses, you may need to re-register and pay the fee again before you can legally use the name.
How much does it cost to file a DBA?
DBA filing fees vary by state, county, and city — there's no single national fee. Most filings fall somewhere between $10 and $100, though some jurisdictions charge more. States that require newspaper publication add a separate cost on top of the filing fee, which can range from $40 to several hundred dollars depending on the publication and how long the notice runs.
The publication requirement is the part that catches people off guard. California and New York both require it, and the cost depends on the newspaper's rates in your county — not a fixed state fee. Budget for it before you file so it doesn't slow down your timeline.
FAQ
It depends on your state and county. Many states let you file a DBA online through the Secretary of State's website or a state business portal. But some jurisdictions — especially those that process DBAs at the county or city level — still require paper forms or in-person filing. Check your state's official business portal first to see what's available where you're filing.
No. A DBA is registered with your state or local government, not the IRS. The IRS doesn't track trade names — it tracks tax entities. Your tax obligations stay tied to your underlying business structure (sole proprietorship, LLC, corporation), not to the DBA name. If you don't already have an Employer Identification Number (EIN), you may want to get one, but that's separate from the DBA filing itself.
Yes, but the requirements are straightforward. Most states ask for your legal business name, business address, entity type, and the DBA name you want to register. LLCs and corporations typically need to provide their state registration number as well. Sole proprietors generally don't need to show prior entity registration — a DBA is often how they establish a business name in the first place.
A DBA is almost always cheaper upfront. DBA filing fees typically run $10–$100, while LLC formation fees range from $50 to $500 depending on the state, plus ongoing compliance costs like annual reports. But cost isn't the only factor. An LLC gives you liability protection — a DBA doesn't. If protecting your personal finances matters to you, the higher cost of an LLC is worth understanding before you decide.
It depends on your state. Most DBA registrations expire after 5 years, though some states set shorter or longer terms. When your DBA expires, you'll need to renew it — and in most cases, pay the filing fee again. Mark your renewal date when you first register so the deadline doesn't catch you off guard.
Yes. Sole proprietors and general partnerships file DBAs all the time without forming an LLC first. In most states, no prior entity registration is required for a sole proprietor to file a DBA — it's one of the most common ways to give a sole proprietorship a distinct business name. If you later form an LLC, you'd file a separate DBA under that entity if you want to keep using the same trade name.
