Most DBAs do not have their own EIN. A DBA is just a name—it does not create a separate business. You still use your personal Social Security Number or your business’s existing EIN. The IRS treats a DBA as a doing business as name, not as a new business entity. Over 30 million small business owners operate under DBAs in the United States, yet 67% of them don’t understand how EINs connect to their DBA names.

Understanding DBAs, EINs, and Business Structures
A DBA stands for “doing business as.” It is a name you use to run your business that is different from your legal name. You might operate as “John’s Web Design” even though your legal name is “John Michael Smith.” The DBA tells customers and the government what business name you operate under. It does not change your business structure or create a new legal entity.
An EIN is an Employer Identification Number. The IRS gives you an EIN to identify your business for tax purposes. Think of it like a Social Security Number, but for your business instead of a person. Sole proprietors sometimes don’t need an EIN, but most business structures do. The EIN connects to your actual business structure, not to your DBA name.
Your business structure is the legal form your business takes. The main structures are sole proprietorships, partnerships, LLCs, and corporations. Your structure determines how taxes work, how you’re legally responsible for debts, and which EIN you use. A DBA works the same way regardless of your structure—it’s still just a name. But whether you need an EIN depends entirely on your business structure.
The IRS does not give EINs to DBAs. DBAs are not recognized as separate businesses by the federal government. When you register a DBA, you register it with your state or county, not with the IRS. The IRS only cares about your actual business structure. Your DBA is simply registered locally for record-keeping and public notice purposes.
Here’s the key relationship: Your business structure determines if you need an EIN, and your DBA is just a name label on top of that structure. If your structure needs an EIN, you use that same EIN for all your DBAs under that business. If your structure doesn’t require an EIN, you use your Social Security Number instead. The DBA name itself never gets its own EIN from the IRS.
Federal Law: How the IRS Treats DBAs
The IRS operates under federal tax code rules about who needs an EIN. Entities that must have an EIN include corporations, partnerships, and LLCs. Sole proprietors without employees can operate under their Social Security Number. A DBA does not change these federal requirements at all.
Here’s why: DBAs are not recognized by the IRS as a business entity. They are recognized by state and county governments only. The IRS only tracks actual business structures. When you file taxes, you report under your business structure’s EIN or your Social Security Number—never under your DBA name. The DBA is invisible to the IRS for tax purposes.
The IRS Form SS-4 is what you use to apply for an EIN. This form does not ask for your DBA name. It asks for your business structure type. If you already have an EIN for your business structure, you don’t need to file another SS-4 just because you’re using a DBA. You apply for one EIN per business entity, not per business name.
Federal law says that if you operate as a sole proprietor without employees, you can use your Social Security Number on tax forms and business accounts. You don’t need an EIN, though you can get one if you want. Many sole proprietors use DBAs without any EIN at all. Some sole proprietors get an EIN for privacy reasons, even though they’re not required to. Federal law permits both options.
Partnerships and LLCs are different. These structures must have an EIN under federal law. When you form an LLC or partnership, you are legally required to get an EIN before you operate. If your LLC operates under a DBA, that DBA does not get a separate EIN—you use your LLC’s EIN. The same rule applies to partnerships.
Corporations always need an EIN. Corporations must have an EIN by federal law, regardless of whether they have employees. If a corporation operates under a DBA, the corporation’s EIN stays the same—it doesn’t change. The DBA is just another name the corporation uses. All tax filings, bank accounts, and legal documents use the corporation’s EIN, not the DBA name.
State and Local Rules: Where DBAs Are Registered
Each state has different rules about DBAs. Some states make registration simple and cheap. Other states require more paperwork and charge higher fees. Some states don’t require DBA registration at all if you’re using your legal name. The key point: DBA registration happens at the state or county level, not at the federal level.
Most states require you to file a DBA registration with the county clerk or secretary of state. You fill out a form that shows your legal name, your DBA name, and your business address. You pay a registration fee, which ranges from $10 to $500 depending on your state. Some states require you to publish your DBA in local newspapers as notice to the public. This publication rule protects consumers by making your business registration public record.
California requires DBA registration with the county clerk. You must also publish your DBA in a local newspaper for four weeks. After publication, you file a proof of publication with the clerk. The entire process takes about six weeks. California charges around $50 to $100 for registration, plus newspaper publication costs of $100 to $500.
Texas does not require DBA registration at all for sole proprietors and partnerships. A sole proprietor in Texas can use a DBA without registering it anywhere. However, if you want a bank account or contract under your DBA name, the bank may require proof that you own the DBA. Texas LLCs and corporations must register with the Texas Secretary of State, but that’s different from DBA registration.
New York requires DBA registration with the county clerk in the county where you operate. The registration fee is around $25. You do not need to publish your DBA in newspapers in New York. The registration lasts for ten years, then you must renew it. New York calls DBAs “assumed names” or “trade names.”
Florida requires DBA registration with the Florida Department of State Division of Corporations. You file online or by mail. The fee is around $50. The registration lasts for five years. You must renew before it expires or you lose the DBA protection.
Pennsylvania does not require DBA registration for sole proprietors using their legal name. If you use a different name, you don’t have to register it with the state, though some municipalities require local registration. This gives Pennsylvania sole proprietors a lot of flexibility. Partnerships and corporations must register with the state, but again, this is separate from DBA registration.
When a DBA Needs Its Own EIN (The Exception)
There is one scenario where a DBA gets its own separate EIN: when you treat it as a separate business structure for legal or operational purposes. This is rare, but it happens.
If you have a sole proprietorship and you want to start a completely separate business under a different DBA, and that second business is a different legal structure, then it gets its own EIN. For example, you might own “Smith Consulting” as a sole proprietorship and “Smith Manufacturing” as an LLC. These are two different structures. Each one needs its own EIN. But both can use your name or your DBAs—that doesn’t matter. What matters is the structure.
You do not get a separate EIN just because you have a DBA. The separate EIN comes from having a separate business entity, not from having a separate name. If you have one LLC and operate it under three different DBAs, all three DBAs share the same EIN. You only need a separate EIN if you actually form a separate business structure—a separate LLC, corporation, partnership, or sole proprietorship with employees.
Some business owners think they need separate EINs for separate DBAs to protect their assets or separate their finances. This is a myth. Your business structure—not your DBA—is what determines legal liability and tax treatment. If you want true legal separation between businesses, you form separate business structures (like multiple LLCs), not just multiple DBAs. Multiple DBAs under one structure don’t provide additional legal protection.
Real-World Scenarios: How DBAs and EINs Work
Scenario 1: Solo Freelancer Using a DBA
Maria is a freelance designer. She operates as a sole proprietor using her legal name, Maria Rodriguez. She wants to brand herself as “Design Solutions.” She registers “Design Solutions” as a DBA with her county. She does not have any employees. She does not have an EIN—she uses her Social Security Number for all tax forms and business accounts.
Maria opens a bank account under “Design Solutions.” The bank allows her to use her DBA name with her Social Security Number. She files her annual tax return as a sole proprietor on Schedule C, reporting all income under her Social Security Number. The IRS doesn’t track her DBA name at all. Her DBA registration with the county is just for public record.
Now Maria hires her first employee. The moment she has an employee, the IRS requires her to get an EIN. She files Form SS-4 and gets an EIN for her sole proprietorship with employees. She still keeps her “Design Solutions” DBA. Her new EIN applies to her sole proprietorship, and her DBA remains just a name. She gives her new employee her EIN for the W-2 form.
| Action | What Happens |
|---|---|
| Register DBA with county | DBA is recognized locally but not by IRS |
| Open bank account with DBA and SSN | No EIN needed if no employees |
| Hire first employee | IRS requires EIN; DBA stays the same |
| File taxes under EIN | All income reports use EIN, not DBA |
Scenario 2: LLC Owner Operating Multiple DBAs
James forms an LLC called “Tech Innovations LLC.” He applies for one EIN from the IRS. His EIN is 12-3456789. James wants to offer three services: web design, app development, and consulting. He registers three DBAs: “Web Works,” “App Masters,” and “James Consulting.”
All three DBAs operate under the same LLC structure. All three use the same EIN: 12-3456789. James opens three separate bank accounts—one for each DBA—but he uses the same EIN for all of them. His customers know him by these three different names, but the IRS only sees one business: Tech Innovations LLC with EIN 12-3456789.
When James files his annual business tax return, he reports all income from all three DBAs under one EIN. He doesn’t file three separate tax returns. The IRS doesn’t care about the three DBA names. James keeps his DBA registrations current with his state. If he stops using “App Masters,” he can let that DBA registration expire. His LLC and its EIN continue unchanged.
| Action | What Happens |
|---|---|
| Form LLC; get one EIN | LLC has single EIN; DBAs are optional |
| Register three DBAs | Each DBA uses the same LLC EIN |
| Open three bank accounts | All accounts share the same EIN |
| File annual tax return | One return reports all DBA income combined |
Scenario 3: Sole Proprietor Upgrading to LLC
David runs a landscaping business as a sole proprietor using his legal name. He has been operating for five years without an EIN, using his Social Security Number. He has no employees. His business grows, and he wants more legal protection. He decides to form an LLC called “David’s Landscaping LLC.”
David files the LLC formation documents with his state. He applies for an EIN for his new LLC. He gets EIN 98-7654321. Now David has a separate legal entity. His LLC can own equipment, sign contracts, and operate bank accounts under the LLC name and the new EIN. His old sole proprietorship technically still exists but is now inactive.
David registers “David’s Landscaping” as a DBA for his LLC if he wants, though technically his LLC name serves as his business name. If he keeps using his sole proprietor DBA from before, he needs to file it under the LLC now. All future income goes to the LLC EIN. His old sole proprietor records remain, but new business uses the LLC structure and new EIN.
| Action | What Happens |
|---|---|
| Sole proprietor operates five years | Uses SSN; no EIN needed |
| Form LLC | LLC requires and gets new EIN |
| Register DBA under LLC | DBA links to LLC EIN, not SSN |
| Transition income to LLC | Future revenue uses new LLC EIN |
The Relationship Between DBAs, EINs, and Business Bank Accounts
Banks require different documentation for different situations. A bank will ask for your legal name, your business structure, and your EIN or Social Security Number. If you want a business bank account under a DBA name, the bank needs proof that you own that DBA.
For a sole proprietor with a DBA, you provide the bank with your personal ID and your DBA registration document. The bank opens an account under the DBA name, but they link it to your Social Security Number. The account is in the DBA name, but it’s under your personal SSN. You can write checks and deposit funds under the DBA name, even though the IRS doesn’t recognize the DBA.
For an LLC or corporation, the process is different. You provide the bank with your business formation documents (like your Articles of Organization for an LLC). You provide your EIN letter from the IRS. The bank opens an account under your business name or DBA name, linked to your EIN. This EIN goes on all your checks and banking documents.
Some banks require a separate EIN for separate accounts. This is a bank policy, not a legal requirement. If you have three DBAs under one LLC, one bank might require you to get separate EINs for each (which the IRS won’t give you), while another bank will let you operate all three under the same EIN. Shop around with banks, because these policies vary.
The IRS doesn’t care what name appears on your bank account. The IRS cares about your EIN or SSN. If you have a bank account under “Design Solutions” but it’s linked to your SSN, the IRS tracks you by your SSN, not by “Design Solutions.” The bank account name and the IRS name don’t have to match.
Tax Filing: How DBAs and EINs Work Together
When you file taxes, your DBA name doesn’t appear on your tax return. Your tax return is filed under your business structure’s name and EIN (or your SSN if you’re a sole proprietor without an EIN). All income from all your DBAs gets reported together.
Sole proprietors file Schedule C (Profit or Loss from Business). This form doesn’t ask for your DBA name—it asks for your business name. Many sole proprietors write their DBA name on Schedule C, and the IRS accepts it. Some sole proprietors write their legal name. Either way, the IRS matches it to your Social Security Number. As long as you report your income, the IRS doesn’t care whether you call yourself “Maria Rodriguez” or “Design Solutions.”
Self-employed people with net profit of $400 or more must pay self-employment tax. This rule applies whether you have a DBA or not. Your DBA doesn’t change your tax obligation. Your business structure and income determine your tax, not your business name.
LLC owners file Form 1040 with Schedule C if their LLC is taxed as a sole proprietorship (single-member LLC). Multi-member LLCs typically file Form 1065, which is a partnership return. Corporations file Form 1120. None of these forms ask for DBA names. They ask for your business structure and EIN.
If you have multiple DBAs under one business structure, you report all income combined. You don’t file separate tax returns for each DBA. If you want truly separate tax treatment, you must have separate business structures (separate LLCs, for example), not just separate DBAs.
Mistakes to Avoid
Mistake 1: Thinking Your DBA Gets an EIN from the IRS
Many people fill out Form SS-4 thinking they’re getting an EIN for their DBA. The IRS doesn’t issue EINs for DBA names. You get an EIN for your business structure. A DBA is just a name. If you apply for an EIN and check the “DBA” box, the IRS still issues you an EIN for your business structure, not for your DBA name. Some people accidentally end up with multiple EINs because they don’t understand this.
Mistake 2: Not Registering Your DBA Because You Think You Need a Federal EIN First
Some people delay registering their DBA because they’re confused about federal requirements. DBA registration is separate from EIN application. You can register a DBA with your state or county right now. You get an EIN from the IRS separately, when your business structure requires it. These are two different processes. Don’t wait for one to do the other.
Mistake 3: Using a DBA When You Actually Need a Separate Business Structure
Some people create multiple DBAs when they should create multiple separate business entities. If you want true liability protection between two business lines, you should form separate LLCs, not just register separate DBAs. Multiple DBAs under one structure don’t protect your personal assets any more than one DBA does. If you want legal separation, you need separate structures. This mistake can leave you unprotected from business liability.
Mistake 4: Failing to Renew Your DBA Registration
Every state has DBA registration renewal deadlines. Some states require renewal every five years, others every ten years. If you miss the renewal deadline, your DBA registration expires. You lose the legal protection of your DBA registration. Customers or competitors can register the same name. You can be sued for using an unregistered business name. This mistake costs money to fix.
Mistake 5: Not Updating Your Business Records When You Add a DBA
Once you register a new DBA, you need to update your business records with banks, insurance companies, and vendors. If you keep banking under your old name but register a new DBA, things get confusing. Your customers might pay invoices to the wrong name. Your insurance might not cover claims under a name you didn’t register. This mistake creates operational chaos.
Mistake 6: Thinking You Need an EIN Just Because You Have a DBA
Sole proprietors without employees do not need an EIN just because they use a DBA. You can legally operate a DBA under your Social Security Number indefinitely if you have no employees. Getting an EIN is optional for you. Some people waste money getting an EIN they don’t actually need. Know your requirements before applying.
Mistake 7: Registering Multiple Business Structures When One Would Do
Some business owners form separate LLCs for each business line to “separate DBAs from EINs.” This creates unnecessary complexity. You end up paying multiple filing fees, multiple annual compliance costs, and multiple tax returns. If you don’t actually need legal separation, just use multiple DBAs under one structure. You’ll save money and reduce paperwork.
Do’s and Don’ts for DBAs and EINs
| Do This | Why |
|---|---|
| Register your DBA locally even if you don’t have an EIN | Protects your right to use that name and provides legal proof |
| Use the same EIN for all your DBAs under one structure | The IRS tracks one business structure, not multiple names |
| Get an EIN if you have any employees | Federal law requires it; you must have it for payroll |
| Update your bank accounts and business records when you add a DBA | Keeps your paperwork organized and reduces confusion |
| Renew your DBA registration before it expires | Losing your DBA registration can create legal problems |
| Get separate business structures if you need true liability separation | Separate EINs come from separate structures, not separate DBAs |
| Keep your DBA registration documents with your business records | You need proof you own the DBA for bank accounts and contracts |
| Don’t Do This | Why |
|---|---|
| Apply for multiple EINs for multiple DBAs under one structure | The IRS won’t give you separate EINs for the same business |
| Wait for a federal EIN before registering your DBA locally | These are separate processes; do both when appropriate for your situation |
| Assume your DBA provides liability protection like a separate LLC would | Liability protection comes from your business structure, not your name |
| Ignore DBA renewal deadlines | Your DBA registration expires and loses legal protection |
| Use a DBA without registering it if state law requires registration | You face fines and lose the right to sue using your business name |
| Tell a bank that your DBA is a separate business to open a separate account | Banks might require separate EINs (which you can’t get), creating problems |
| Mix income from multiple DBAs as if they’re separate businesses on your taxes | Report all income under one business structure unless you have separate structures |
Pros and Cons: DBAs, EINs, and Different Business Structures
| Aspect | Pros | Cons |
|---|---|---|
| DBA Without EIN | Low cost; simple; no federal paperwork; good for testing business ideas | No liability protection; can’t hire employees easily; banks might hesitate; less professional appearance |
| DBA With EIN | Some privacy (your SSN not on business accounts); slightly more professional; ready to hire employees | Costs money to apply; annual compliance requirements if you later have employees |
| Sole Proprietor Structure | Simplest to start; lowest costs; easy to manage; no annual filings in most states | Personal liability for business debts; no liability protection; harder to get business loans |
| LLC Structure | Liability protection; more professional image; flexibility in taxation; can appear larger | Annual filing fees; more paperwork; more complex setup than sole proprietorship |
| Multiple DBAs Under One Structure | One EIN to manage; streamlined taxes; lower costs; one set of business records | Can seem disorganized; harder to separate finances; no legal separation between business lines |
| Multiple Separate Structures | True liability separation; clear business distinction; professional; audits affect only relevant business | Higher costs; more annual filings; multiple tax returns; more complex accounting |
How to Register a DBA and Apply for an EIN
Step 1: Check Your State’s DBA Requirements
Contact your state’s secretary of state office or county clerk to learn if DBA registration is required in your state. Ask: Do I have to register my DBA? Where do I register? What’s the fee? How long does registration last? What documents do I need?
Step 2: Prepare Your DBA Documents
You’ll need your legal name, your DBA name, your business address, and your business description. Some states ask for your Social Security Number or EIN if you have one. Some states ask why you’re registering the DBA. Write down the exact DBA name you want—it must be the name as it will appear on contracts and bank accounts.
Step 3: File Your DBA Registration
File with your county clerk, secretary of state, or online portal, depending on your state. Pay the registration fee, which ranges from $10 to $500. Some states require you to publish your DBA in a local newspaper. If your state requires publication, follow those instructions—get proof of publication and file it with your registration if required.
Step 4: Decide If You Need an EIN
Ask yourself: Is my business a sole proprietorship, partnership, LLC, or corporation? Do I have employees? Do I plan to hire employees soon? If you’re a sole proprietor with no employees and no plans to hire, you likely don’t need an EIN. If you have any other structure, or if you have employees, you need an EIN.
Step 5: Apply for an EIN (If Needed)
If you need an EIN, go to the IRS website and apply online for free using Form SS-4. The online application takes about ten minutes. You get your EIN immediately. You don’t need to provide your DBA name—just your business structure name and your business structure type. If you prefer not to apply online, you can mail or fax Form SS-4, but that takes longer.
Step 6: Open Your Business Bank Account
Take your EIN letter (or your DBA registration if you don’t have an EIN) and your personal ID to a bank. Tell the bank you want to open a business account under your DBA name. Provide whichever documentation the bank requests. The bank will set up your account under your DBA name but linked to your EIN or SSN. You get a business checkbook and debit card in your DBA name.
Step 7: Update Your Business Records
Add your DBA and EIN (if you have one) to your business records. Give your EIN to any employees, insurance companies, and vendors who ask. Update your website, business cards, and social media with your DBA name if you’re using it publicly. Keep copies of your DBA registration and EIN letter in a safe place.
Key Entities and Their Roles
The IRS (Internal Revenue Service): The federal government agency that collects taxes. The IRS issues EINs, but only for actual business structures, never for DBA names. The IRS doesn’t care about your DBA—it only tracks your business structure and EIN or Social Security Number.
Your Secretary of State: Each state’s secretary of state office oversees business registration. They maintain the official record of business formations (LLCs, corporations) in your state. Some states also handle DBA registration through the secretary of state. Others assign DBA registration to county clerks.
Your County Clerk: The county government office that handles local business registration. In many states, the county clerk registers DBAs. This office maintains public records of DBAs in your county. They also handle business licenses in some cases.
SBA (Small Business Administration): A federal agency that supports small business owners with loans, education, and resources. The SBA doesn’t register DBAs or issue EINs, but it provides guidance about starting a business.
Banks and Financial Institutions: Banks are not government agencies, but they have important roles. Banks require you to provide proof of your right to use a DBA before they’ll open an account under that name. Banks also set their own policies about EINs and business accounts, which may vary.
State Tax Agencies: Most states have a state department of revenue or similar agency. They handle state business licenses and state income tax. State rules about DBAs vary widely. Some states require DBA registration; others don’t. Some states charge DBA fees; others are free.
Your Business Structure (LLC, Corporation, etc.): Your business structure is the legal form your business takes. The structure determines whether you need an EIN, how you pay taxes, and what liability protection you get. DBAs don’t change your structure—they’re just names applied on top of your structure.
Important Court Rulings and Legal Precedents
The IRS has consistently ruled that DBAs do not create separate tax entities. A DBA is treated as a sole proprietorship operation if the business structure is a sole proprietorship. Partnerships operating under DBAs are treated as partnerships. This ruling means you cannot escape liability or taxes by simply registering a DBA under a different name.
In many states, using a DBA without registering it (when registration is required) can result in fines. Some courts have ruled that business owners who fail to register required DBAs cannot sue customers or suppliers using that business name. This means you lose legal rights if you don’t follow your state’s DBA registration rules.
State courts have upheld that DBAs do not shield you from personal liability the way a business structure does. If you operate a sole proprietorship under a DBA and cause someone harm, they can sue you personally—your DBA doesn’t protect you. Only actual separate business structures like LLCs provide that protection.
Federal vs. State: Key Differences Explained
| Aspect | Federal Law | State Law |
|---|---|---|
| DBA Registration | No federal registration required | Each state has different requirements; some require it, some don’t |
| EIN Issuance | IRS issues EINs only for business structures | States don’t issue EINs; states register business structures |
| Taxes | IRS collects federal income and self-employment taxes | State income tax rules vary; some states have no income tax |
| Liability | Federal law doesn’t address DBA liability; business structure determines it | State law defines how liability works for different business structures |
| Name Rights | No federal registration protects your DBA name | State DBA registration protects your right to use that name locally |
| Renewal | If you have a federal EIN, there’s no renewal—it lasts forever | DBA registrations expire and must be renewed per state law |
| Publication | Federal law doesn’t require publishing your business name | Some states require newspaper publication of your DBA |
FAQs
Does my DBA automatically get an EIN?
No. Your DBA does not get its own EIN. The IRS does not issue EINs for DBA names—only for business structures. If your business structure requires an EIN, you apply for one EIN for your whole structure. That same EIN covers all your DBAs under that structure.
Can I use a DBA without registering it?
It depends. Some states don’t require DBA registration at all. Texas, for example, doesn’t require sole proprietor DBA registration. Other states, like California, require registration or you face fines. Check your state’s rules. Even if registration isn’t required, registering protects your legal rights to use that name.
How many DBAs can use the same EIN?
Unlimited. You can have one business structure with one EIN and register 100 DBAs if you want. All your DBAs share the same EIN. The IRS only sees one business—your actual structure. Your 100 DBA names are just that—names.
If I have a DBA, do I have to get an EIN?
No, not necessarily. If you’re a sole proprietor with no employees, you don’t need an EIN just for having a DBA. You can use your Social Security Number forever. If you have employees, you need an EIN. If your structure is an LLC, partnership, or corporation, you need an EIN regardless of DBA status.
Can I register the same DBA in multiple states?
Usually yes. You can register the same DBA name in different states. However, once you register a DBA in a state, others in that state usually can’t register the same name. Different states have different name availability rules. Check availability in each state before registering.
What happens if I don’t renew my DBA registration?
Your registration expires. Once expired, you lose the legal protection of your registration. Others can register the same name. You can’t use your business name in lawsuits. You’ll need to renew and pay fees again to restore it.
Does a DBA give me liability protection like an LLC?
No. Liability protection comes from your business structure, not your DBA name. A sole proprietor with a DBA still has personal liability. You need an LLC or corporation for liability protection. A DBA is just a name—it doesn’t shield your personal assets.
Can I file taxes under my DBA name instead of my business structure name?
No, not exactly. You file taxes under your business structure (sole proprietorship, LLC, etc.). You can put your DBA name on your tax return, but the IRS matches it to your EIN or SSN based on your structure. Your DBA name helps, but your EIN or SSN is what the IRS actually tracks.
If I have three DBAs, do I need three separate bank accounts?
No. You can have one bank account under your business structure name and use all three DBAs within it. Some business owners open separate accounts for each DBA to keep finances organized. Banks sometimes require separate accounts for different DBAs. Ask your bank what they allow.
Do I need to register a DBA if I’m using my legal name for my business?
No, usually. If your business name is literally your legal name, you generally don’t need to register a DBA. Once you use any different name, you likely need to register it as a DBA. Check your state—some states don’t require registration even for assumed names.
How much does DBA registration cost?
It varies by state. Registration costs range from free to $500. Most states charge $25 to $100. Some states charge more for publication fees if newspaper publication is required. Check your specific state and county for exact costs.
What’s the difference between a DBA and a trademark?
They protect different things. A DBA protects your local right to use a name in your state. A trademark is a federal registration that protects your name or logo nationally and internationally. Trademarks provide stronger national protection. Many business owners register both.
If I form an LLC, do I still need to register a DBA?
Not required. Your LLC name is your legal business name. You don’t have to register a DBA unless you want to operate under a different name. Many LLC owners register DBAs to offer services under different brand names without forming new LLCs.
Can I get an EIN over the phone?
No. The IRS only issues EINs online, by mail, or by fax. You cannot call and get an EIN. Online is fastest—you get your EIN immediately. Mail and fax take longer. Go to the IRS website for details.
Do I need an EIN if I’m a sole proprietor with one employee?
Yes. The moment you hire your first employee, federal law requires you to have an EIN. You cannot pay employees using your Social Security Number. You must have an EIN to handle payroll.
If I rename my DBA, do I get a new EIN?
No. Your EIN is tied to your business structure, not your DBA name. You can change your DBA name as many times as you want. The same EIN applies. The IRS doesn’t care about your DBA name changes—it tracks you by your structure and EIN.
