How to search Kansas business entities online — Secretary of State Business Lookup

Kansas business entity records are searchable at sos.ks.gov/eforms/BusinessEntity/Search.aspx, operated by the Kansas Secretary of State. The older URL path no longer resolves — the current search is at the eforms subdirectory. No account is required for public searching; an account is needed only for filing.

What the search covers

The database covers all entities registered with the Kansas Secretary of State: domestic and foreign LLCs, profit corporations, nonprofit corporations, limited partnerships, limited liability partnerships, and registered agents. General partnerships and sole proprietorships registered at the county level are not included here.

How to search

Name searches use a starts-with match by default. Entering a partial name returns all entities whose names begin with that string. An entity ID search — entering the SOS-assigned identifier — retrieves the exact record directly. The portal supports filtering by entity type and status to narrow large result sets.

Entity detail page

Each record displays the entity name, type, status, entity ID, formation or registration date, registered agent name and address, and officer or member information from the most recent filing. A filing history tab lists all documents on file; document images are accessible from there.

Foreign entity note

Foreign LLCs and foreign corporations registering in Kansas file paper applications — Kansas does not accept foreign entity formation filings online. The Secretary of State accepts those by mail or in person. Domestic entities file online through the eforms portal.

Biennial reports

Kansas uses biennial reports rather than annual reports for most entity types. The report is due every two years and can be filed online through the Secretary of State's eforms system.
