What a DBA Is in Kentucky (Assumed Name)

A "DBA" - short for "doing business as" - is a trade name a business uses that is different from its legal name. Kentucky law calls this an assumed name, and you register it by filing a Certificate of Assumed Name under KRS 365.015. A sole proprietor named Dana Lee who wants to operate as "Bluegrass Bakery," or an LLC whose legal name is "Lee Holdings LLC" that wants to run a storefront called "Bluegrass Bakery," each need an assumed name on file to use that public-facing name lawfully.

Filing an assumed name does not create a separate legal entity and does not change your liability. It simply puts the public on notice of who is behind the trade name. If you want liability protection, you need an actual entity such as an LLC - see our national what is a DBA explainer for how a DBA compares with forming an entity.

Businesses register an assumed name for practical reasons. A sole proprietor may want to trade under a professional brand rather than a personal legal name. An existing LLC may launch a second product line, storefront, or website that needs its own name without forming a whole new company. Banks typically require an assumed-name certificate before they will open a deposit account or process card payments in a name that differs from the account holder's legal or entity name - so the DBA is often the missing piece that lets a business collect money under its brand. Because the certificate is a public record, it also helps customers and vendors identify who they are actually dealing with, which is the underlying policy purpose of KRS 365.015.

Where You File: Secretary of State vs County Clerk

Kentucky splits assumed-name filings by who is registering the name. Under KRS 365.015, registered entities file at the state level and unregistered businesses file locally:

If a registered entity operates in several counties, the state-level filing covers it statewide; a sole proprietor operating in multiple counties may need to file in each county where it does business. Because your legal entity's true name is already on record - for an LLC, on its Articles of Organization - the assumed name is an additional public name layered on top of it. This division matters for cost and process: the state filing is a flat $20 with a standard form, while county clerk filings use local forms and fees that differ from one county to the next. If you are unsure which category you fall into, the deciding question is simple: are you already registered with the Kentucky Secretary of State? If yes, you file the assumed name there; if you are an unregistered sole proprietor or general partnership, you file with the county clerk.

How to File a Kentucky Assumed Name, Step by Step

  1. Choose and check the assumed name. Pick the trade name and make sure it is distinguishable from existing entity and assumed names. Search the Secretary of State's business records, and check that the name does not infringe a federal trademark.
  2. Determine where to file. If you are an LLC, corporation, or limited partnership, file with the Kentucky Secretary of State. If you are a sole proprietor or general partnership, file with your county clerk.
  3. File the Certificate of Assumed Name. Complete the certificate with your true name, the assumed name, and your address, then pay the fee - $20 at the Secretary of State (county fees vary). Entities can file with the state online or by mail.
  4. Track the five-year renewal. Calendar the renewal date. A Kentucky assumed name is effective for five years, and you must renew to keep it active.

After filing, use the assumed name on signage, marketing, and contracts, and provide the certificate to your bank if you want to accept payments under the trade name.

Kentucky DBA Fees and Renewal (2026)

The state-level Certificate of Assumed Name fee is $20. County clerk fees for sole proprietors vary, so confirm with your county. Verify current state fees on the Secretary of State fee schedule before filing.

Name Rules and Availability

Your assumed name must be distinguishable from existing names on file and cannot use words that falsely imply a different entity type - for example, a sole proprietor's assumed name cannot include "LLC," "Inc.," or "Corporation," because those suggest a registered entity that does not exist. Before filing, search the Secretary of State's business database to confirm availability, and consider a broader trademark search if you plan to build a brand. Approving an assumed name for filing does not guarantee you have the right to use it against a prior trademark holder.

What a Kentucky DBA Does and Doesn't Do

A DBA lets you operate and market under a trade name, open a bank account in that name, and appear consistent to customers. A DBA does not create a separate legal entity, provide liability protection, change how you are taxed, or grant exclusive rights to the name. It does not replace an EIN, a business license, or a registered agent. Many small businesses use a DBA alongside an LLC: the LLC provides the liability shield and the DBA provides a customer-facing brand.

DBA, EIN, and Tax Considerations

Filing an assumed name does not require a new EIN. According to the IRS, operating under a trade name does not change your federal tax identification - you keep the same EIN (or your Social Security number if you are a sole proprietor without employees). If you sell taxable goods or services under the DBA, you still register for a Kentucky sales and use tax account with the Kentucky Department of Revenue using your underlying entity or individual. For how an LLC is taxed, see S-corp vs LLC.

Renewal, Change, and Withdrawal

A Kentucky Certificate of Assumed Name is effective for five years from the date of filing. To keep the name active, you file a renewal with the same office before the certificate expires; the Secretary of State renewal fee is the same $20 as the original filing. If you let it lapse, your legal right to use the assumed name ends, and the name may become available for someone else to register. It is worth calendaring the expiration the day you file, because the state generally does not guarantee a reminder the way it mails annual report notices for LLCs.

If the facts behind the assumed name change - for example, the entity behind it changes its legal name, or you stop using the trade name entirely - Kentucky provides for amending or withdrawing the certificate under KRS 365.020. Withdrawing a name you no longer use is good housekeeping: it removes the public record and frees the name. When you dissolve the underlying entity, remember that the assumed name does not automatically end its own separate life on the register, so address it as part of winding the business down.
