Form a Connecticut LLC — or skip the wait with a ready-made company

Connecticut offers a strategic location between New York City and Boston. With a $120 filing fee and an $80/year annual report, the Constitution State provides moderate-cost access to one of the wealthiest consumer markets in the country.

Connecticut's economy is anchored by financial services, insurance (Hartford is the Insurance Capital), healthcare, defense manufacturing and biotech. The state has one of the highest per-capita incomes and a highly educated workforce.

For non-residents, Connecticut's graduated income tax (up to 6.99%) and biennial Business Entity Tax ($250 minimum) make it expensive to maintain. Wyoming or Arizona offer significantly lower ongoing costs — which is exactly why our ready-made companies are Wyoming LLCs.

Forming in Connecticut means filing the Certificate of Organization, waiting for state approval, then applying to the IRS for an EIN — and only then can a bank or Stripe fully onboard you. A ready-made Wyoming LLC removes that queue because the EIN already exists.

All fees below are sourced from the Connecticut Secretary of State fee schedule.

Step 1: Choose your LLC name

Search for available names on the Connecticut Business Entity Search. Your name must include "Limited Liability Company," "LLC," or "L.L.C." Ensure the name is distinguishable from existing entities on file.

Step 2: Appoint a registered agent

Every Connecticut LLC must have a registered agent with a physical street address in Connecticut. The agent must be available during normal business hours to accept legal documents on behalf of the LLC.

Step 3: File the Certificate of Organization

File online through the Connecticut Secretary of State. The filing requires:

• LLC name with designator
• Registered agent name and CT address (recommended)
• Principal office address
• Name and address of each organizer
• Management structure
• $120 filing fee

Step 4: Create an Operating Agreement

While not always legally required in Connecticut, an Operating Agreement is essential for banking, tax compliance, and internal governance. It establishes member rights, profit distribution, and management structure. We include a custom Operating Agreement in every formation package.

Step 5: Obtain an EIN

Apply for an Employer Identification Number (EIN) from the IRS. This is your LLC's tax ID number, required for banking, hiring, and tax filings. Online application is available for those with an SSN; fax or mail application for international applicants without an SSN. (A ready-made Wyoming LLC skips this entirely — the EIN is already issued.)

Step 6: Register for Connecticut taxes (if applicable)

If you will sell taxable goods or services in Connecticut, register with the Connecticut Department of Revenue for applicable tax accounts including sales tax and income tax withholding if you have employees.

Annual compliance requirements

1. Annual report: Due during anniversary month. Fee: $80.
2. Business Entity Tax: Biennial $250 minimum, every two years.
3. Federal tax filing: Form 5472 with pro forma 1120 for foreign-owned LLCs.
4. CT income tax: 3%–6.99% graduated rates on CT-sourced income.
5. Sales tax: 6.35% statewide.
6. Registered agent: Recommended with CT address.
7. FinCEN BOI Report: Required.

Connecticut taxes for LLCs

Connecticut's combined ongoing costs ($80/year report + ~$125/year effective BET) make it expensive for LLC maintenance. Best for businesses with actual CT operations.

Processing times

Connecticut offers same-day expedited processing for $50. A ready-made Wyoming LLC is faster still — it already exists, so there's nothing to wait for.
