How to search Ohio business entities online

What the search covers

The database covers for-profit corporations, nonprofit corporations, professional associations, foreign corporations and foreign name registrations, business trusts, real estate trusts, limited liability companies, limited liability partnerships, and limited partnerships, along with fictitious names, trade names, name reservations, trademarks, and service marks — all in the same system.

Coverage has some historical gaps: filings before 1973 were maintained manually and were only computerized for businesses still active at that time, and document images are complete only from 1997 forward (earlier filings were microfilmed).

Search options — six modes

Ohio's search is more flexible than most state portals:

• Business Name — standard name search with Begins With and Contains options, filterable by status (All, Active, Cancelled, Dead, or Fraudulent)
• Exact Business Name — matches the exact name only
• Prior Business Name — searches former names for entities that have been renamed
• Agent/Registrant — the statutory agent for most entities, or the registrant name for trade names, trademarks, and similar filings
• Organizer/Incorporator — finds all entities organized by a specific individual or organization, with an optional location-of-incorporation filter
• Number Search — by Document ID or Entity Number (this serves as the charter number for domestic corporations, license number for foreign corporations, or registration number for LLCs, LPs, LLPs, trade names, and similar filings)

A separate Trademark/Service Mark search covers mark number, mark description, and registrant name.

Ohio's no-annual-report policy

Ohio does not require annual reports for most business entities — no LLC annual report, no corporation annual report. This is one of the most significant cost and compliance advantages in Ohio's business environment. LLPs are the main exception, filing a biennial report between April 1 and July 1 of odd-numbered years ($25 for both domestic and foreign LLPs). Confirm current requirements for specific entity types at ohiosos.gov, as rules can change.

The absence of annual reports also means Ohio's database does not automatically show whether entities have been actively maintained. A record showing "Active" status reflects the formation date and any amendments — it does not indicate the entity filed a recent report, because there is no such report to file.
