Kansas DBA — there is no DBA filing in Kansas (2026)
Kansas does not register DBAs. The Kansas Secretary of State's Register a Business page states that "Sole proprietors do not register with the Kansas Secretary of State." and, of the business-entity application, that "This application does not register an assumed, fictitious, trade, or DBA (doing business as) name." There is no county filing and no state filing, and no fee. You may operate under a trade name without registering it anywhere.
The one thing to knowThere is no Kansas DBA filing to make — not at the county, not at the state. Entity registration with the Secretary of State (for an LLC or corporation) is a different filing and does not register a trade name.
The process
- Check whether you need to file anything
You do not. Kansas offers no DBA, assumed-name, fictitious-name or trade-name register, at the county or the state. Sole proprietors file nothing.
- Use the name
You may operate under a trade name without registering it. Name rights come from use, not from a filing Kansas does not offer.
- Register the ENTITY if you have one
Corporations, LLCs, LPs and LLPs formed under the Kansas General Corporation Code register the entity itself with the Kansas Secretary of State. That is entity formation, not a DBA.

Kansas-specific details
Most states offer a DBA or assumed-name register, usually at the county. Kansas does not. The Secretary of State's Register a Business page (https://sos.ks.gov/businesses/register-a-business.html) says "Sole proprietors do not register with the Kansas Secretary of State." and, of the business-entity application, "This application does not register an assumed, fictitious, trade, or DBA (doing business as) name." A page telling you to file one at the county clerk — including an earlier version of this guide — is describing a filing that does not exist. For name protection, a federal trademark is the available route; check your city or county for local business license requirements, which are separate from any name registration.
What to bring
- Nothing — there is no Kansas DBA filing to make
