SOS Business Search

How to search Maine business entities online

Updated August 2026

Quick Answer

Maine's business search is ICRS at apps3.web.maine.gov/nei-sos-icrs/ICRS, run by the Secretary of State. Search by the exact business name (or a keyword with the % wildcard) or charter number after passing a reCAPTCHA, then open the result for the registered agent and filing history. The older icrs.informe.org address no longer leads to the search tool — it now redirects to the general Maine.gov portal instead, so use the apps3.web.maine.gov address directly.

  1. Go to ICRS at apps3.web.maine.gov/nei-sos-icrs/ICRS (pass the reCAPTCHA).
  2. Search by the exact name (or a keyword plus the % wildcard) or charter number.
  3. Select "view list of filings" to see the registered agent and full history.

What the search covers

The database includes domestic and foreign LLCs, profit corporations, nonprofit corporations, limited partnerships, and limited liability partnerships registered with the Secretary of State. Assumed business names (DBAs) registered at the county level are not in this database.

How to search

Name searches work best with the exact business name, or a keyword combined with the % wildcard — the search checks the legal name plus any former, assumed, or fictitious names on file, so narrowing to less common words gives better results. A charter number search retrieves a single entity directly.

Selecting an entity from results displays the legal name, former and assumed names, charter number, filing date, jurisdiction, and status, plus the clerk or registered agent name and address and the principal office address. Selecting "view list of filings" shows the full filing history.

Current processing time

As of August 2026, the Maine Secretary of State lists corporate filing processing time at approximately 40–55 business days. This is a notable backlog compared to many states — plan accordingly if you need a formation effective date to land within a specific window. Expedited service may be available for certain filings; confirm directly with the Division of Corporations before filing.

Annual reports

Maine annual reports are due June 1 of each year. The fee is $85 for domestic LLCs and profit corporations ($150 for foreign entities), and $35 for nonprofits. Reports can be filed online through the ICRS portal or by paper submitted to the Augusta office.

Frequently Asked Questions

Does the Maine business search include DBAs or assumed business names?

No. The Maine Secretary of State's ICRS search covers LLCs, corporations, nonprofits, limited partnerships, and limited liability partnerships, but assumed business names (DBAs) are registered at the county level and aren't included in this database.

How do I search for a business name in Maine's ICRS system?

Search works best with the exact business name, or a keyword combined with the % wildcard — the system checks the legal name plus any former, assumed, or fictitious names on file. If you have the charter number, entering it retrieves that entity directly.

Why doesn't icrs.informe.org work for Maine business searches anymore?

That older address no longer leads to the search tool — it now redirects to the general Maine.gov portal. The current Maine business entity search is at apps3.web.maine.gov/nei-sos-icrs/ICRS, and no account is needed, though you'll need to pass a reCAPTCHA check.
