Connecticut Company Formation and Compliance Guide

Before forming or operating a company in Connecticut, review entity type, registered-agent records, annual reports, state tax, federal tax, and e-commerce bookkeeping requirements.

Reference LLC state filing feeThe standard state fee for an LLC certificate of organization is generally $120. Confirm on the state website before filing.
Ongoing filingThe annual report fee is generally $80. Confirm on the state website before filing.
Typical due-date ruleAn LLC annual report is generally filed between January 1 and March 31 each year.

01

What to confirm before filing

Confirm entity type, owners, management, name, business activity, registered agent, and any in-state address requirements. An LLC and a corporation have different governance, tax elections, and recurring filings; first-year price alone is not a sound basis for choosing.

After formation, use the state business portal to review tax, employer, and industry-license registrations.

02

Ongoing state compliance

The annual report fee is generally $80. Confirm on the state website before filing. An LLC annual report is generally filed between January 1 and March 31 each year.

03

E-commerce and sales tax

Cross-border sellers should test economic nexus using sales, transactions, inventory, and marketplace collection records. Review the taxability of digital goods and specified services as well.

04

Federal tax and foreign ownership

State formation does not replace federal tax filing. A U.S. entity with foreign ownership may involve an EIN, Form 1120, Form 5472, Form 1065, withholding, or information returns. The applicable filing depends on tax classification, ownership, transactions, and operating facts.

05
