Business Registers in Connecticut: Secretary of the State (CONCORD)

Overview

Connecticut's official business entity register is managed by the Connecticut Secretary of the State (SOTS) through the CONCORD portal (Connecticut Online Corporations and Registration Database). The Business Services division handles entity formations, amendments, dissolutions, registered agent changes, and annual report filings.

Covered entity types include domestic and foreign corporations, LLCs, LLPs, LPs, statutory trusts, nonprofit corporations, and other formally organized entities. Private companies have no obligation to file financial statements with any state authority, and there is no public repository of company accounts. Beneficial ownership is handled federally through FinCEN under the Corporate Transparency Act, not through the state register.

For KYB and AML purposes, the CONCORD portal covers entity name verification, status, registered agent, and officer or director data where filed. Financial statements and UBO information are not publicly available.

Official Registers

Connecticut Secretary of the State: CONCORD

The Connecticut Secretary of the State maintains the official register through the CONCORD portal. The portal supports search by entity name or business ID, with status filtering.

Each entity detail page shows the legal name, entity type, business ID, state or country of formation (for foreign entities), filing date, registered agent name and address, principal office address, and officers or directors where filed.

LLCs and nonprofits must file an Annual Report by March 31 each year to stay active. For-profit corporations use a different deadline: they file by the last day of their formation anniversary month. Fees are among the higher in the United States: $80 for domestic LLCs, $150 for domestic for-profit corporations ($435 for foreign corporations), and $50 for nonprofits. Failing to file leads to administrative dissolution; foreign entities face revocation of their state registration.

Connecticut repealed its Business Entity Tax (BET) effective January 1, 2020. The BET had been a $250 biennial tax on LLCs, LPs, and LLPs. No equivalent obligation replaced it; entities subject to the BET now owe nothing to the state beyond their SOTS annual report fee.

Trade names and assumed names are registered with the town clerk of the town where the principal place of business is located, not with the Secretary of the State. Town clerk registrations are local records and do not appear in the CONCORD portal.

Certified copies of filed documents and Certificates of Legal Existence (Good Standing) are available through the SOTS for a fee, ordered through CONCORD or by mail.

FinCEN: Beneficial Ownership Information (Federal)

Beneficial ownership reporting in the United States is governed federally under the Corporate Transparency Act (CTA), which took effect on January 1, 2024. The CTA requires certain entities (called "reporting companies") to file beneficial ownership information (BOI) reports with the Financial Crimes Enforcement Network (FinCEN), a bureau of the U.S. Department of the Treasury.

A reporting company must disclose each beneficial owner who directly or indirectly exercises substantial control over the entity or holds at least 25% of its ownership interests.

Following an interim final rule issued in March 2025, FinCEN exempted all U.S.-domestic entities and U.S. persons from BOI reporting. The obligation now applies only to certain foreign companies registered to do business in the U.S. that fall outside the enumerated exemptions (covering large operating companies, regulated financial institutions, tax-exempt entities, and others).

The BOI database is not publicly accessible. It is available only to authorized government agencies and, under certain conditions, to financial institutions with customer consent. There is no public UBO register for U.S. entities.

Registration and Publication Requirements

Corporations and LLCs

All Connecticut corporations (for-profit and nonprofit) and LLCs must file formation documents with the SOTS: Articles of Incorporation for corporations, Articles of Organization for LLCs. Foreign entities must register before transacting business in Connecticut.

LLCs must file an Annual Report by March 31 each year to stay active ($80 domestic). For-profit corporations file by the last day of their formation anniversary month ($150 domestic, $435 foreign). Domestic nonprofit corporations pay $50 by March 31. Private companies have no obligation to file or publish financial statements. Tax filings go to the Connecticut Department of Revenue Services and the IRS, but are not publicly accessible.

Sole Proprietorships and Trade Names

Sole proprietorships need no Secretary of the State registration and require no formal formation step. Businesses trading under a name other than the owner's legal name register that trade name with the town clerk of their principal town. These registrations are local records and fall outside the CONCORD portal.

Partnerships

General partnerships need no SOTS registration. Limited partnerships must file a Certificate of Limited Partnership. LLPs must register with the SOTS and file annual renewals. Registered entities must file dissolution documents with the SOTS on winding up.

Nonprofit Corporations and Statutory Trusts

Nonprofit corporations file Articles of Incorporation with the SOTS and must file an annual report ($50) by March 31. Charitable organizations soliciting in Connecticut face separate registration requirements under the Connecticut Solicitation of Charitable Funds Act, administered by the Office of the Attorney General.

Statutory trusts organized under the Connecticut Statutory Trust Act register with the SOTS and carry their own renewal obligations.
