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 varies by state, but it generally takes 7 steps: find your filing agency, check name availability, gather your documents, file your forms, pay the fee, publish notice if required, and renew on time.
What a DBA is
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 — but the purpose is the same: it gives you the legal right to use that name in commerce.
A DBA doesn't create a new legal entity. It doesn't give you liability protection, a separate tax ID, or any of the structural benefits of forming an LLC or corporation. It's a name registration — nothing more. If you're a sole proprietor, your DBA name is tied to you personally. If you're an LLC, the DBA is an additional trade name layered on top of your existing entity.
Who needs a DBA
DBAs aren't required for most businesses, but they're useful in several common situations. A sole proprietor who wants to operate under a business name — rather than their own name — needs a DBA. An LLC that wants to market under a different brand name needs one too. And a business expanding into a new state may need to file a DBA there to use its existing name.
Most banks also require a DBA registration before they'll open a business bank account in a trade name. That's a practical reason many business owners file one early — even when it's not legally required.
How to file a DBA online
The DBA filing process follows the same general path in most states, though the specific agency, fees, and publication rules vary. Most states let you file online, but some require county-level filing in person. Work through these 7 steps to get your DBA registered.
Step 1: Find your filing agency
DBA filings are handled at the state or local level — and which one depends on where your business operates. Some states route everything through the Secretary of State's office. Others require you to file at the county clerk's office, or both. If you're expanding into a new state or county, you'll need to file a DBA there separately.
Step 2: Check name availability
Your DBA name can't already be in use by another business in your jurisdiction. Check your state's business name database before you file — most Secretary of State websites have a free search tool. Review your state's naming rules at the same time. Some states restrict certain words or require specific disclosures depending on your business type.
Step 3: Gather your information
Before you file, pull together the details you'll need on the application. This typically includes your legal business name, your business address, your entity type (sole proprietorship, LLC, corporation), and the DBA name you want to register. If you're an LLC or corporation, you'll also need your state registration number.
Step 4: File your forms
Most states let you file a DBA online through the Secretary of State's website or a state business portal. Some states — particularly those that require county-level filing — don't offer online filing and require you to appear in person or mail in your forms. Check your state's process before assuming you can do it all online.
Step 5: Pay the filing fee
Every state charges a fee to register a DBA. The amount varies widely — from under $20 in some states to over $100 in others — and county-level filings may carry their own separate fees on top of any state fee. Pay at the time of filing. Most online portals accept credit cards.
Step 6: Publish notice if required
Some states require you to publish a notice of your DBA registration in a local newspaper — typically once a week for several consecutive weeks. This is a public notice requirement, not optional. States like California and New York have publication rules that catch people off guard. Check whether your state requires it before you consider the filing complete.
Step 7: Renew on time
DBAs don't last forever. Most states set an expiration period — commonly 5 years — after which you need to renew or refile. If your DBA lapses, another business can register that name. Mark your renewal date when you file so it doesn't sneak up on you.
FAQ
Yes, in most states. Many Secretary of State offices and state business portals let you file a DBA online and pay the fee by credit card. The exception is states that require county-level filing — some counties don't offer online filing and require you to file in person or by mail. Check your specific state and county before starting.
It depends on your state and county. DBA filing fees range from under $20 in some states to over $100 in others. If your state requires county-level filing, you may pay separate fees at both levels. Some states also charge additional fees for publication requirements. Check your state's Secretary of State website for the exact amount.
It depends. Your LLC already has a registered legal name, so you don't need a DBA to operate under that name. But if you want to run a second brand, market under a different name, or expand into a new state using a name other than your LLC's legal name, you'll need to file a DBA for that additional name.
No. A DBA is a state or local registration — the IRS doesn't require you to register a DBA name separately. You file taxes under your legal business name and Employer Identification Number (EIN), regardless of what DBA names you operate under. That said, if you're a sole proprietor without an EIN, getting one is worth doing — it keeps your Social Security number off business documents.
A DBA is cheaper upfront. DBA filing fees are typically $20–$100, while LLC formation fees range from $50 to $500 depending on the state. But a DBA doesn't give you liability protection — your personal finances are on the hook for any business debts or legal claims. An LLC costs more to form, but it creates a legal separation between you and your business.
Yes, but not much. Most DBA applications ask for your legal business name, business address, entity type, and the DBA name you want to register. If you're an LLC or corporation, you'll typically need your state registration number. Sole proprietors usually just need their name and address. Requirements vary by state, so check your filing agency's instructions before you start.
