Kansas: Assumed-Name (DBA) Registration Requirements

How Kansas handles a business name that is not the legal name

Kansas has no general state DBA-registration procedure. The Secretary of
State's current filing catalogue says its entity-name-reservation application
"does not register an assumed, fictitious, trade, or DBA" name. Its current
foreign-business application is equally direct: DBA, fictitious, assumed, and
trade names "are not registered" with that office, and the form accepts only
the foreign entity's legal name.

That leaves no Kansas DBA certificate to file, no state DBA deadline or fee,
no newspaper-publication step, no registration term or renewal, and no penalty
for failing to make that nonexistent filing. This answer is limited to the
general state DBA question. Entity formation, foreign qualification,
professional or local licensing, tax registration, and trademark law are
separate systems.

Two Secretary of State filings are easy to confuse with a DBA:

• Entity-name reservation is for a future legal entity name. Under
  § 17-7923(b), an applicant may reserve an available covered-entity or LLC-series
  name for exclusive use for 120 days. The Secretary's filing catalogue
  expressly says that application does not register a DBA.
• A partnership statement records authority, not an assumed name. Under
  § 56a-303(a), a partnership may file a statement naming the partnership and
  identifying partners' authority. Section 56a-303(g) cancels that statement
  after five years unless it was earlier canceled or amended. The filing's
  purpose and five-year life do not create a five-year Kansas DBA registration.

What trips people up

• A generic DBA certificate is not a Kansas filing. Kansas's general state
  scheme does not designate county clerks or registers of deeds as DBA filing
  offices. A separate city or county business-license rule may still matter,
  but it is not a statewide assumed-name registration.
• The entity-name search is not a DBA database. Kansas searches and reserves
  legal names of registered entities. The Secretary of State does not accept
  DBA names into that filing system.
• A foreign business still registers its legal entity. The current foreign
  application tells the applicant to use the legal name from its home
  jurisdiction and not to insert a DBA, assumed, fictitious, or trade name.
• Name protection is a separate question. With no DBA registration, merely
  using a trade name does not obtain the 120-day statutory exclusivity that
  § 17-7923 gives a qualifying entity-name reservation.

Common questions

Where do I file a Kansas DBA?

There is no general Kansas DBA filing office. The Secretary of State expressly
does not register DBA, fictitious, assumed, or trade names.

Does a sole proprietor register with the Secretary of State?

No. The Secretary's current business-registration page says sole proprietors do
not register with that office. A sole proprietor should separately check any
business-license, tax, or professional rules that apply to the activity.

Is the partnership statement of authority a DBA filing?

No. Section 56a-303 lets a partnership record who can act for it, particularly
for transactions and real-property transfers. It is not an assumed-name
certificate.

Can I reserve the DBA for 120 days?

No. Section 17-7923's 120-day reservation protects a proposed covered-entity or
LLC-series name. The Secretary of State says the reservation application does
not register an assumed, fictitious, trade, or DBA name.
