In Kentucky, a DBA is officially called an assumed name. An LLC that wants to operate under a name different from the legal name in its Articles of Organization files a Certificate of Assumed Name with the Kentucky Secretary of State. The current state filing fee is $20, and the registration lasts five years.
Kentucky adds a local step that many guides miss. For an LLC or other registered entity, KRS 365.015 requires a filed copy of the assumed-name certificate to go to the county clerk where the entity maintains its registered agent. Under the current county-clerk fee schedule, a filing of five pages or fewer is $33. Sole proprietors follow a different route: they file the assumed-name certificate directly with the county clerk where they maintain their principal place of business.
The Secretary of State now lists assumed-name filing and renewal in FastTrack, so eligible registered entities can use the online system as well as the paper form. This guide focuses on the decision and filing rules for Kentucky assumed names; for the broader entity setup, use the Kentucky LLC guide.
An out-of-state LLC whose name is unavailable in Kentucky does not use a DBA for this. Form FBE has a separate line for the name it will use here, explained in the Kentucky foreign LLC guide.
Kentucky DBA Filing at a Glance
How do you file a DBA in Kentucky?
An LLC files a Certificate of Assumed Name with the Kentucky Secretary of State for $20. The assumed name must be distinguishable on the Secretary of State's records, the registration lasts five years, and renewal is available for successive five-year terms. A filed copy also goes to the appropriate county clerk. Sole proprietors skip the Secretary of State and file with the county clerk where they maintain their principal place of business.

What Is a DBA in Kentucky?
The term "DBA" stands for "doing business as." While it's widely used across the country, Kentucky's official terminology is "assumed name." If you're searching state forms or the SOS website, look for "Certificate of Assumed Name" — that's the document you need.
An assumed name is not a separate business entity. It's simply a registered alias your existing business can use publicly — on contracts, invoices, signage, bank accounts, and marketing materials. Filing a Certificate of Assumed Name doesn't create a new LLC, change your tax status, or provide any additional liability protection.
Quick Example
Suppose your LLC is registered as Bluegrass Digital Solutions, LLC but you want clients to know you as BDS Creative. You'd file a Certificate of Assumed Name for "BDS Creative" with the Kentucky Secretary of State, pay $20, and you can then legally use that name in your business operations. Your legal entity remains Bluegrass Digital Solutions, LLC.
Do You Need a DBA for Your Kentucky LLC?
Most LLC owners file a DBA for one of these reasons:
- Brand simplification — Your LLC name is formal or long. A DBA lets you use a shorter, catchier public name without changing your legal registration.
- Multiple business lines — One LLC, two different brands. A landscaping LLC might use one name for residential and another for commercial clients.
- Name mismatch — You formed your LLC quickly under one name but pivoted your business idea. A DBA gets you the name you actually want without refiling Articles of Organization.
- Domain/brand alignment — Your LLC name isn't available as a domain, but a DBA variation is. The DBA makes the alternative name legally usable.
If none of those scenarios apply, you probably don't need one. Operating under your exact registered LLC name — including the "LLC" designator exactly as filed — requires no additional paperwork.
When a DBA Is the Wrong Move
A DBA is the right tool for a narrow set of situations. It's the wrong tool when your goals go beyond brand presentation.
If the goal is to separate ownership, contracts, finances or liability exposure between two operations, a DBA does not create that separation. Both assumed names remain part of the same legal entity. In that situation, compare the simplicity of one LLC with multiple brands against the legal and administrative separation of forming another entity; the right structure depends on the business rather than on the $20 assumed-name fee alone.
Similarly, if your main concern is that your current LLC name is taken in another state where you're expanding, a DBA doesn't solve that — it only registers the name in Kentucky. You'd need to qualify as a foreign entity in the other state and address the naming conflict there directly.
The Kentucky LLC annual report and other compliance requirements remain the same regardless of how many DBAs you hold. For a full overview of Kentucky LLC maintenance requirements, see our Kentucky LLC hub.
Kentucky DBA Filing Fee
| Business Type | Where You File | Current Baseline Fee | What to Know |
|---|---|---|---|
| LLC / corporation / registered entity | Secretary of State + county clerk copy | $20 state + $33 county* | Separate state and county filings under KRS 365.015 |
| Sole proprietor | County clerk where principal place of business is maintained | $33* | No Secretary of State assumed-name filing |
| Renewal — registered entity | Same filing route as original certificate | $20 state + county fee* | File within the six months before expiration |
| Amendment / withdrawal | Secretary of State and corresponding local filing when applicable | $20 state | Use the current SOS form for the action |
*KRS 64.012 currently sets $33 for covered county-clerk filings of five pages or fewer. Longer documents can cost more.
This means the $20 headline fee is not the complete filing cost for a Kentucky LLC. The Secretary of State fee and county-clerk fee pay for two different statutory filings. If you are comparing a DBA with changing the LLC's legal name, remember that an assumed name changes only the name used in business; it does not amend the LLC's Articles of Organization.
How to Register a DBA in Kentucky
The filing process differs based on your business structure. LLCs file with the Kentucky Secretary of State. Sole proprietors file at the county level. Follow the path that matches your situation.
For LLCs, Corporations, and Partnerships
Run a Kentucky DBA Name Search
Use the Kentucky Secretary of State business search to screen the proposed assumed name. For a certificate filed with the Secretary of State, KRS 365.015 requires the assumed name to be distinguishable from names already on record. Treat the search as a screening step rather than a trademark clearance.
Check Naming Requirements
Check the Secretary of State's current naming rules and any industry-specific restrictions before filing. An assumed name accepted by the Secretary of State is not a trademark clearance and does not authorize a business to use regulated terminology it is otherwise prohibited from using.
Download and Complete the Certificate of Assumed Name Form
Use the current Certificate of Assumed Name (ASN) form or FastTrack filing. The filing identifies the assumed name, the entity's real legal name, its organization type/jurisdiction, mailing address and an authorized signer. A separate certificate is required for each assumed name.
Prepare Two Copies
For mail or in-person filing, the current instructions require one exact or conformed copy with the filing. After the Secretary of State filing, obtain the filed copy for delivery to the local county clerk. For an LLC that maintains a Kentucky registered agent, the county is the county where that registered agent is maintained.
Submit the Filing and Pay $20
If filing on paper, send the completed form and $20 check (payable to Kentucky State Treasurer) to:
Michael Adams, Office of the Secretary of State
P.O. Box 718
Frankfort, KY 40602-0718
In person: 1025 Capital Center Drive, Suite 201, Frankfort, KY 40601 (8:00 AM–4:30 PM ET). Questions: (502) 564-3490. FastTrack also lists online assumed-name filing.
File the Stamped Copy with the County Clerk
File the Secretary of State–filed copy with the county clerk required by KRS 365.015. For an LLC, that is generally the county where the entity maintains its registered agent. The current county fee is $33 for a filing of five pages or fewer. Keep proof of both filings with the LLC's records.
For Sole Proprietors
Sole proprietors skip the Secretary of State assumed-name filing. KRS 365.015 directs an individual to file the certificate with the county clerk where the person maintains his or her principal place of business. The statewide SOS distinguishability rule applies to certificates filed with the Secretary of State, so an individual filing only at county level follows a different name-review path. Trademark and other naming rights can still matter.
Common Mistakes When Filing a Kentucky DBA
A few errors show up frequently — mostly from people who've filed DBAs in other states and assume Kentucky works the same way.
- Assuming one SOS filing covers everything. It doesn't. The county clerk step is a separate requirement, not a formality. If you skip it, your DBA registration is incomplete — and that creates real problems when opening bank accounts, signing contracts, or dealing with any institution that asks for proof of DBA registration.
- Searching only for exact matches. The SOS business entity search surfaces similar names, not just identical ones. "Kentucky Heights Property Group" can conflict with "Kentucky Heights Properties LLC." Review surrounding results, not just the exact phrase you entered.
- Filing with a name that contains restricted words. "University," "Bank," and "Attorney" require additional authorization. If you include one of these without the proper approval documentation, the SOS will reject the filing — and you'll restart the process.
- Not tracking the five-year renewal date. The Secretary of State is not required to send a renewal certificate, so track the five-year expiration yourself. Renewal can be filed during the six months before expiration.
- Using the DBA before filing is complete. The name isn't legally usable until both the SOS stamped your certificate and the county clerk has your copy on file. Using it before then — on invoices, a website, a bank account — creates exposure if the filing gets rejected.
Kentucky DBA Name Search
The business entity search is the primary tool for screening an assumed name. Review more than an exact match: Kentucky requires a Secretary-of-State-filed assumed name to be distinguishable from names already on record. If you want the broader distinguishability rules and state-search workflow before choosing the DBA, use the Kentucky LLC name search guide.
One practical note: the SOS search interface works better when you search the distinctive part of your name rather than the full phrase. Searching "Blue River" surfaces more potential conflicts than searching "Blue River Consulting LLC." Our Secretary of State business search guide has tips for getting more accurate results.
Where to Search
Kentucky Assumed Name vs LLC
A DBA and an LLC serve different purposes. Confusing the two leads to a real gap in expectations — particularly around liability protection, which a DBA does not provide.
| Feature | Kentucky DBA (Assumed Name) | Kentucky LLC |
|---|---|---|
| Creates legal entity? | No | Yes |
| Liability protection? | No | Yes |
| Separate tax filing? | No | Depends on structure |
| Requires registered agent? | No | Yes |
| Filing fee | $20 (SOS) | $40 (Articles of Organization) |
| Annual report required? | No (separate from LLC) | Yes — $15/yr |
| Name protection (state) | Limited — distinguishable only | Registered name protected |
| Term / expiration | 5 years (renewable) | Indefinite (with compliance) |
The most important distinction: a DBA does not protect your personal assets. If you're a sole proprietor operating under a DBA and someone sues your business, they're suing you personally. The DBA is just a name — it doesn't create the liability firewall that an LLC does. That said, if you already have an LLC and you're adding a DBA, the LLC's liability protection still applies to the business activities conducted under the assumed name.
If your main goal is liability protection, you need an LLC — not a DBA. For a sharper comparison of when to use each structure, our DBA vs LLC guide walks through the decision in more detail. If you're ready to form the LLC itself, our Kentucky LLC formation guide covers the full process from start to finish.
Do Kentucky DBAs Expire?
If the five-year term expires without a timely renewal, the registration is no longer in its active term. Because Kentucky requires a valid assumed-name filing when an entity transacts business under a name other than its real name, do not treat expiration as a harmless grace period. File the renewal during the six-month window before expiration.
How to Renew a Kentucky DBA
The Kentucky LLC annual report and the DBA renewal are completely separate filings — renewing one does not affect the other. The Kentucky LLC annual report and assumed-name renewal are separate compliance obligations with different schedules.
Can Someone Else Use Your DBA?
This is where most DBA holders run into a false sense of security. The Secretary of State applies a distinguishability screen when it accepts state-filed assumed names, but the filing itself does not create exclusive rights. It does not by itself stop:
- Someone registering your DBA name as a federal trademark
- An out-of-state business using the same name in Kentucky
- Sole proprietors filing the same or similar name at the county level
- Another business using the name in a completely different industry
DBA vs Trademark
A federal trademark gives you nationwide exclusive rights to use a name in a specific product or service category. A DBA gives you the legal right to use a name in Kentucky — nothing more. The Kentucky SOS doesn't check federal trademark registrations when approving a DBA filing. It's possible to receive a valid state stamped certificate for a name that someone else already holds a trademark on — and using it commercially can expose you to infringement claims regardless of your SOS filing.
Do You Need a New EIN for a Kentucky DBA?
Your EIN is assigned to your LLC as a legal entity, not to any name it operates under. Whether your LLC operates under one name or five assumed names, it's still a single entity with one EIN. Taxes are filed under the LLC's legal name and EIN regardless of which DBA is on the invoice.
The only scenario where you'd need a new EIN is if you form a separate legal entity — a second LLC, a corporation, etc. A DBA doesn't trigger that requirement.
Before filing, confirm the LLC's registered-agent information is current because that information determines the county-clerk destination for an entity that maintains a Kentucky registered agent. If the agent or registered office has changed, update the Secretary of State record rather than routing the assumed-name copy using stale information.
If you're still working through the Kentucky LLC setup — EIN, operating agreement, registered agent — our Kentucky LLC guide has the full step-by-step breakdown.
To file a DBA in Kentucky, an LLC submits a Certificate of Assumed Name to the Kentucky Secretary of State for $20. Then file the required copy with the county clerk where your registered agent is maintained; a filing of five pages or fewer currently costs $33 at the county level. The assumed name is valid for five years and can be renewed for successive terms. Run the SOS business entity search first to confirm your name is available — it must be distinguishable from all other state-registered names. A DBA doesn't create liability protection, doesn't change your tax ID, and doesn't give you trademark rights. It's a name registration, not a new entity.

Frequently Asked Questions
Cost, Term and Filing Method
How much does it cost to file a DBA in Kentucky?
For an LLC or other registered entity, the Secretary of State fee is $20. Kentucky also requires the filed certificate to be delivered to the appropriate county clerk; the current county-clerk fee is $33 when the filing is five pages or fewer. A sole proprietor files with the county clerk where the principal place of business is maintained rather than with the Secretary of State.
How long does a Kentucky DBA last?
A Kentucky assumed name registration is valid for five years from the date it is filed with the Secretary of State. You can renew it for another five-year term by filing a Certificate of Renewal of Assumed Name within six months before expiration. The renewal fee is $20.
Can I file a Kentucky DBA online?
Yes. Kentucky FastTrack currently lists “File Certificate of Assumed Name” as an online business-entity service. Paper filing remains available using the current ASN form and $20 Secretary of State fee.
Name Protection, EIN and Search Questions
Does a Kentucky DBA protect my business name?
No exclusive ownership is created by the filing itself. Kentucky law expressly says an assumed-name certificate does not automatically prevent use of that name or protect the name from use by others. The Secretary of State does apply a distinguishability requirement to state-filed certificates, but trademark and other naming rights are separate questions.
Do I need a new EIN when I file a DBA in Kentucky?
No. Your existing LLC's EIN covers all assumed names operated under that legal entity. A DBA is not a separate entity — it's an alias. No new tax identification number is issued or required when you register a Kentucky assumed name. You continue to file taxes under your LLC's legal name and existing EIN.
Where do I search for DBA name availability in Kentucky?
Use the Kentucky Secretary of State's free business entity search at sos.ky.gov. Your proposed assumed name must be distinguishable from all names currently on record with the state — including existing LLC names, corporation names, and previously filed assumed names. For a federal trademark screen, use the USPTO's current Trademark Search system at tmsearch.uspto.gov.
LLC Differences, Renewal and Cancellation
What is the difference between a DBA and an LLC in Kentucky?
A DBA (assumed name) is simply a registered name alias for your business — it doesn't create a legal entity, doesn't provide liability protection, and doesn't require a separate EIN. An LLC is a legal entity registered with the state that separates your personal assets from business liabilities. A DBA costs $20 and lasts five years; forming an LLC costs $40 and continues indefinitely with annual compliance. Most business owners form an LLC first, then file a DBA if they need to operate under an alternate name.
What happens if I miss the Kentucky DBA renewal?
Your assumed name registration lapses after five years if not renewed. There's no grace period or automatic extension. Once lapsed, another business can register the same name through the SOS. You'd need to file a new Certificate of Assumed Name ($20) to re-register the name — assuming it's still available. Set a calendar reminder within the six months before your expiration date to ensure uninterrupted registration.
Do I need to file a DBA for each county in Kentucky?
For an LLC or other registered entity, file the Certificate of Assumed Name with the Secretary of State and then file the required copy with the county clerk identified by KRS 365.015. A sole proprietor follows the county-only route and files where the individual maintains the principal place of business.
Can I cancel my Kentucky DBA?
Yes. File a Certificate of Withdrawal of Assumed Name with the Kentucky Secretary of State to cancel an active assumed name registration. The withdrawal fee is $20. This removes the name from active state records. If you are winding down the entire LLC, withdrawing the assumed name is only one part of the broader closure process.
