How to search Kansas business entities online
Updated August 2026
Official Resource
Kansas Official SOS WebsiteKansas 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.
Verification step on the search page
The business search requires completing a short verification puzzle before it will return results. This confirms you're not an automated tool — no account or login is needed to search.
What the search covers
The database covers all entities registered with the Kansas Secretary of State: domestic and foreign LLCs (including series and public benefit LLCs), profit corporations, nonprofit corporations, limited partnerships, limited liability partnerships, and business trusts. General partnerships are not required to register with the Secretary of State, though they may file a Statement of Partnership Authority; sole proprietors do not register at all.
How to search
The search form lets you look up a business by name, by Kansas Secretary of State ID (the entity's assigned identifier), or by current resident agent name, and choose whether the term should match names that start with it or simply contain it. Before results are returned you must complete a short verification puzzle — this is a bot-prevention step, not a login requirement.
Entity detail page
Each record displays the business ID, name, entity type, jurisdiction, status, formation date, principal office address, resident agent name and registered office address, and the last reporting year with report due dates (and a forfeiture date, if applicable). A documents list shows filings on file, with some documents available to view or download directly.
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 can file most original documents online.
Information reports
Kansas requires an information report every two years instead of an annual report. Entities formed in even years file in each following even year; those formed in odd years file in each following odd year. For-profit entities are due by April 15 and nonprofits by June 15 of their respective year. A three-month delinquency period follows the due date, after which the business forfeits and must be reinstated before it can file anything else.
