To create a DBA, you choose a business name that’s available in your jurisdiction, file an assumed-name application with your state or county (whichever your state designates), pay a filing fee that usually runs between $10 and $150, and, in some states, publish a notice in a local newspaper before the registration is complete.1U.S. Small Business Administration. Choose Your Business Name The specifics vary by state, county, and sometimes city, so the first real step is confirming which office handles the filing where you do business.
Figure Out Whether You Need One
A DBA, short for “doing business as,” lets you operate under a name that isn’t your legal name or your company’s registered name. You need one in a few common situations:
- You’re a sole proprietor and want to use anything other than your personal surname. If your name is Maria Gonzalez and you want to sell candles as “Bright Harbor Candles,” the DBA connects that brand to you in the public record.
- You’re in a general partnership and want a single business name instead of listing every partner.
- You already have an LLC or corporation and want to run a separate brand, product line, or division under a different name. An LLC called “Bright Harbor Enterprises LLC” that wants to market “Bright Harbor Candles” needs a DBA for the second name.
Before you start filing, understand what a DBA is not. It does not create a separate legal entity, and it does not shield your personal assets from business debts or lawsuits. The SBA is direct about this: registering a DBA name does not provide legal protection on its own.1U.S. Small Business Administration. Choose Your Business Name If a sole proprietor operating under a DBA gets sued, personal accounts and property are still exposed. Liability protection comes from forming an LLC or corporation, not from the DBA.
Pick a Name That Will Clear
Your proposed name needs to be distinguishable from names already on file in your jurisdiction. Before you fill out any paperwork, search the database kept by your county clerk or Secretary of State. Many states offer a free online name-availability search. If an identical or confusingly similar name is already registered, the application will likely be rejected.
Most jurisdictions block certain words:
- “Corporation,” “Inc.,” “LLC,” and “Limited” are off-limits unless you’re actually organized as that entity type. Those terms signal a specific legal structure, and using them falsely misleads customers and creditors.
- “Bank,” “Trust,” “Insurance,” and “Savings” are restricted in many states because they imply government-regulated financial activities. Using them typically requires approval from a state financial regulator.
One point to keep in mind as you shop for a name: filing a DBA does not give you exclusive rights to it. Multiple businesses can hold the same DBA within a single state.1U.S. Small Business Administration. Choose Your Business Name That’s different from an entity name, which the state protects once registered. If you want exclusivity over a brand name, that’s a federal trademark question, which is a separate filing with the U.S. Patent and Trademark Office.
File the Application
Where you file depends on your state. Some states process DBAs through the Secretary of State. Others push the filing down to the county clerk. A few require filings at both levels. Check with the government office that handles business filings for your location before you start.1U.S. Small Business Administration. Choose Your Business Name
The application itself is usually short. You’ll typically provide:
- Your full legal name, or the legal name of your LLC, corporation, or partnership
- Your physical business address (some jurisdictions won’t accept a P.O. box, because the filing exists partly so you can be served with legal notices)
- The DBA name you want to register
- A brief description of your business activities
Many jurisdictions require you to sign the application in front of a notary public. Standard notary acknowledgment fees run between $2 and $25 in most states, though roughly ten states have no statutory cap and let notaries set their own rates. Remote online notarization, where available, usually costs more.
Filing fees vary. Depending on your state and county, plan on $10 to $150, with most jurisdictions in the $20 to $50 range. Online filing portals tend to process faster and give immediate confirmation of receipt. Mailed applications usually require a certified check or money order.
Once approved, you’ll receive a stamped copy of the application or a certificate of assumed name. Hold onto it. You’ll need it to open a business bank account and may need it when signing commercial contracts.
Handle Publication, If Your State Requires It
A handful of states require you to publish a notice of your new DBA in a newspaper of general circulation in the county where you do business. It’s a transparency rule meant to alert the public to who stands behind a business name. Where required, the notice typically runs once a week for four consecutive weeks.
After the final notice runs, the newspaper issues an affidavit of publication, a sworn statement confirming the ad appeared as required. You file that affidavit with the county clerk or recording office to complete the registration. Deadlines matter here: missing the publication window, often 30 to 45 days from the initial filing, can void the entire DBA and force you to start over.
Budget for publication before you file. Costs can dwarf the filing fee itself, running from a few hundred dollars to well over a thousand depending on the newspaper and location. Call the paper designated for legal notices in your county and get a quote so the total doesn’t surprise you.
After You File: EIN, Bank Account, Taxes
A DBA doesn’t change your tax situation. Sole proprietors still file Schedule C on their personal return, partnerships still file a partnership return, and LLCs and corporations continue under whatever structure they elected. The DBA is invisible to the IRS in the sense that it doesn’t create a new taxable entity.
You generally don’t need a new Employer Identification Number just because you added a DBA. The IRS states that a sole proprietor doesn’t need a new EIN for a name or location change; a new EIN comes into play only when you incorporate, form a partnership, or go through bankruptcy.2Internal Revenue Service. When to Get a New EIN
A DBA paired with a federal EIN lets you open a business bank account under your trade name.1U.S. Small Business Administration. Choose Your Business Name Banks commonly ask for an EIN (or your Social Security number if you’re a sole proprietor), your business formation documents, any ownership agreements, and a business license.3U.S. Small Business Administration. Open a Business Bank Account Bring the DBA certificate with you; most banks want to see it before they’ll let you deposit checks written to your trade name.
Keep the Registration Current
DBA registrations expire. Five years is the most common term, with some jurisdictions running up to ten. File a renewal application and pay the renewal fee before the current registration lapses. Let it expire and you lose your rights to the name and may face penalties for continuing to operate under an unregistered identity.
If anything changes mid-term, such as your business address, the addition or departure of a partner, or a change in the entity that owns the DBA, file an amendment with the office where you originally registered. Outdated filings create the same legal problems as having no filing at all.
When you stop using a DBA, formally cancel it. The process typically involves filing a statement of abandonment or cancellation with the original filing office and paying a small fee. In jurisdictions that required publication for the initial filing, you may need to publish a notice of abandonment as well. An old DBA left active still ties that name to you in the public record, which can mean legal papers served at an address you no longer occupy, or exposure to activities carried out under a name you thought you’d left behind.
What Happens If You Skip the Filing
Operating under an unregistered business name is more than a paperwork oversight. In many states, you can’t file a lawsuit or enforce a contract in court using a trade name you never registered. If a customer refuses to pay a large invoice, you may be locked out of court until you fix the registration. Some states treat operating without a required DBA as a misdemeanor, and monetary penalties can apply.
Even where criminal exposure is unlikely, the practical fallout bites. Banks won’t open accounts under an unregistered name. Vendors and landlords may refuse to sign contracts. If you’re sued, the gap in registration can complicate your ability to bring counterclaims on behalf of the business. Filing the DBA on the front end is cheaper and faster than fixing any of those problems later.
