How to search Maine business entities online
Official Resource
Maine Official SOS WebsiteMaine's business entity records are searchable at apps3.web.maine.gov/nei-sos-icrs/ICRS, operated by the Maine Secretary of State Division of Corporations. The older icrs.informe.org address no longer leads to the search tool — it now redirects to the general Maine.gov portal. The current system is at the apps3.web.maine.gov address. No account is required for public searching, though the search does require passing a reCAPTCHA check.

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.
