Before going into the details, here is a quick checklist for registering a DBA in Kentucky.
| Official Term | Assumed name (certificate of assumed name) [1] |
|---|---|
| Filing Agency | County clerk in the county of the principal place of business for sole proprietors; the Kentucky Secretary of State for LLCs, corporations, limited partnerships, and other registered entities [1] |
| Form | Certificate of Assumed Name (ASN), filed with the Secretary of State by registered entities [2] |
| State Fee | $20 per certificate of assumed name at the Secretary of State; county recording fees are set under KRS 64.012 and vary by county [2] |
| Processing Time | Online filings through the Secretary of State are generally processed promptly; mailed filings take longer [3] |
| Renewal Required | Yes. A Kentucky assumed name is effective for five years and must be renewed within six months before it expires [1] |
| Cancellation | File a Certificate of Withdrawal of Assumed Name (CWA); the Secretary of State fee is $20 [4] |
A DBA stands for "Doing Business As." It is an alternative name your business uses instead of its registered legal name. In Kentucky, the official term is "assumed name," and the filing is called a certificate of assumed name.
Any type of business can register an assumed name in Kentucky. This includes sole proprietorship, general partnerships, LLCs, and corporations. The filing path depends on your business structure.
A DBA does not create a new legal entity. It does not change your tax status, your liability protection, or your ownership structure. It is only a name your business is authorized to operate under.
| Brand Fit | Commercial Banking | Multi-Entity Branding | Privacy & Trust |
|---|---|---|---|
| Sole proprietors operate under their personal names by default. An assumed name lets you do business under a professional brand instead. | Kentucky banks generally require a registered assumed name before opening a business account in a name other than your legal name. | One entity can run several brands or product lines under separate assumed names without forming a new company for each. | An assumed name keeps your personal identity off public branding and signals to customers that you are an established business. |
How you register an assumed name in Kentucky depends on your business type. LLCs, corporations, and other registered entities file a certificate of assumed name with the Kentucky Secretary of State. Sole proprietors file with the county clerk in the county where they maintain their principal place of business.
Filing an assumed name in Kentucky does not stop another business from using the same or a similar name. Under KRS 365.015, filing a certificate of assumed name does not, by itself, give you exclusive rights to the name. [1]
That makes your own due diligence important. You can search existing business names for free through the Kentucky Secretary of State business records, and registered entities can begin a filing through the FastTrack assumed name search. Because the state will not protect the name for you, a clear search protects your brand. [7]
Kentucky's assumed name rules are light, but a few hard limits apply.
| Match designators to your real structure | No exclusive rights from filing | Conflicts are your responsibility |
|---|---|---|
| A sole proprietor should not use "LLC," "Inc.," or "Corp" in an assumed name. An organizational identifier should match your actual business structure, not imply one you do not have. | Filing a certificate of assumed name does not prevent others from using the same name, so confirm the name is truly available before you build a brand on it. [1] | The state does not screen assumed names for conflicts, so run a federal trademark search to avoid infringing a protected mark. [5] |
Run a trademark search at the U.S. Patent and Trademark Office (USPTO) as well. Filing an assumed name in Kentucky gives you no trademark rights and does not stop a federal trademark holder from challenging your use of the name. [5]
Your filing office depends on your business structure. Registered entities file a Certificate of Assumed Name with the Kentucky Secretary of State. Sole proprietors file a certificate of assumed name with the county clerk in the county of their principal place of business. [1]
| Situation | Fee |
|---|---|
| File a certificate of assumed name with the Secretary of State (LLC, corporation, or other registered entity) | $20 per certificate [2] |
| File with a county clerk (sole proprietor) | County recording fee set under KRS 64.012; for example, $46 in Jefferson County (Louisville) [6] |
| File a Certificate of Withdrawal of Assumed Name with the Secretary of State | $20 [4] |
Online: Kentucky Secretary of State online services, for certificate of assumed name filings by registered entities [3]
By mail: Office of the Secretary of State, P.O. Box 718, Frankfort, KY 40602-0718
County filings: Contact the county clerk in the county of your principal place of business, such as the Jefferson County Clerk [6]
Note: County filings are commonly notarized, while filings with the Secretary of State are not. Confirm the exact recording fee with your county clerk before you submit, because county fees vary.
A certificate of assumed name is effective on the date it is filed. Online filings with the Secretary of State are generally processed promptly, while mailed filings and county recordings take longer. [1]
Keep the file-stamped certificate. Banks, vendors, and payment processors will ask for it before they let you operate or accept funds under the assumed name.
A Kentucky assumed name is not permanent. It is effective for a term of five years from the date it is filed, and you must file a renewal certificate within six months before it expires to keep using the name. The Secretary of State is not required to send a renewal reminder. [1]
A DBA and an LLC are not the same thing. This is one of the most common points of confusion for new business owners, and getting it wrong can be costly.
A DBA is only a name. It does not create a legal entity. It does not protect your personal assets. If someone sues your business, your personal finances are exposed.
Forming an LLC means you are creating a separate legal entity. That separation generally protects your personal finances, home, and savings from business debts and lawsuits.
If you are a sole proprietor who wants a business name without incorporating, an assumed name is a fast, affordable option. If you want liability protection, you need an LLC or a corporation.
Many businesses do both: they form an LLC and then apply for a DBA to run a brand under a name different from the LLC's legal name.
| Feature | DBA (Assumed Name) | LLC |
|---|---|---|
| Creates a legal entity | No | Yes |
| Personal asset protection | No | Yes |
| Changes the tax treatment | No | Can elect a different tax status |
| Required to operate under a different name | Yes, if the name differs from your legal name | No, the LLC name is its legal name |
| Cost to register | $20 state fee or county fee + Swyft service fee | State filing fee + Swyft service fee |
Most Kentucky assumed name problems come down to the same handful of errors. Here is what to watch out for before you file.
Sole proprietors file with the county clerk in the county of their principal place of business, while LLCs, corporations, and other registered entities file with the Secretary of State. Filing in the wrong place wastes time and money. [1]
Filing an assumed name in Kentucky does not give you exclusive rights, so the same name can sit on file more than once. Do your own search before you commit to a brand. [1]
A sole proprietor cannot include "LLC," "Inc.," or "Corp" in an assumed name unless the business is actually organized that way. The designator must match your real structure.
A Kentucky assumed name is effective for only five years. Calendar the renewal so you can file the renewal certificate within the six months before it expires and avoid a lapse. [1]
An assumed name is only a name. It does not create a legal entity and does not shield your personal finances. If you want protection, form an LLC.
State approval is not trademark clearance. A federal trademark holder could still force you to stop using the name. [5]
