Key Takeaways
- Connecticut allows incoming LLC domestication directly (Conn. Gen. Stat. §§34-642 through 34-646 (Title 34, Chapter 616, "Entity Transactions")) — your LLC keeps its original formation date
- Filing fee: $100 for the Certificate of Domestication, plus Connecticut's public-organic-document (formation) fee for the new Connecticut LLC — roughly $220 total combined; confirm the exact current split with the Secretary of the State
- No new EIN is needed. Connecticut's domestication framework (§34-646, "Effect of Domestication") is built around continuity of the same entity, so the IRS treats your EIN as unchanged — update your address with the IRS (Form 8822-B) once your Connecticut registered agent is set.
- No. Connecticut's filing doesn't require proof the LLC withdrew from its prior state; that remains a separate obligation under the old state's own law.
- Same-day LLC domestication filing available through LLC Attorney, at no markup on state fees
If your LLC is formed in another state but you've relocated (or your business has) and want Connecticut to be its new legal home, domestication lets you make that move without dissolving the company and starting over.
This guide covers exactly how to domesticate an LLC into Connecticut in 2026 — the required plan of domestication, the Certificate of Domestication filing, the roughly $220 total cost, and what happens to your EIN and formation date.
What Is LLC Domestication?
Domestication (sometimes called continuance or statutory conversion) lets you move your LLC from one state to Connecticut without dissolving it and starting over. Done correctly, the LLC keeps its original formation date, its EIN, and its contracts — only its home state changes.
Can You Domesticate an LLC Into Connecticut?
Yes. Connecticut's LLC Act includes a statutory domestication provision (Conn. Gen. Stat. §§34-642 through 34-646 (Title 34, Chapter 616, "Entity Transactions")), so an out-of-state LLC can become a Connecticut LLC directly while retaining its original formation date.
How to Domesticate Your LLC in Connecticut
- Filing agency: Connecticut Secretary of the State
- Form: Certificate of Domestication, filed with a Connecticut Certificate of Organization
- Filing fee: $100 for the Certificate of Domestication, plus Connecticut's public-organic-document (formation) fee for the new Connecticut LLC — roughly $220 total combined; confirm the exact current split with the Secretary of the State
- Processing time: About 5 business days for routine processing; 24-hour expedited service available for an extra fee
- Expedited option: 24-hour expedited service for an additional fee
- Certificate of Good Standing: Not required by Connecticut.
- Plan of domestication: A formal plan of domestication must be adopted and filed alongside the conversion paperwork.
- Member approval: Connecticut's approval rule cascades in three layers (§34-643): first, whatever your LLC's own organic rules (operating agreement) specify, if they address domestication; if silent, then whatever your entity's merger-approval rules require; and if both are silent, approval defaults to all interest holders entitled to vote — effectively unanimous. On top of that, any member who would take on new personal liability as a result of the domestication must individually consent, regardless of the general vote threshold, unless they already agreed to that outcome in the governing documents.
What Happens to Your EIN, Contracts, and Formation Date?
Domesticating to Connecticut preserves your LLC's original formation date — the entity continues, it doesn't restart.
No new EIN is needed. Connecticut's domestication framework (§34-646, "Effect of Domestication") is built around continuity of the same entity, so the IRS treats your EIN as unchanged — update your address with the IRS (Form 8822-B) once your Connecticut registered agent is set.
All existing contracts, bank accounts, licenses, and pending liabilities carry over automatically once the domestication is effective — §34-646 establishes that the domesticated LLC continues as the same entity, not a new one stepping into its shoes.
Do I Need to Close My LLC in My Old State?
No. Connecticut's filing doesn't require proof the LLC withdrew from its prior state; that remains a separate obligation under the old state's own law.
If your business keeps operating in the old state after moving its legal home to Connecticut (an office, employees, or regular in-state activity there), you'll likely need to foreign-qualify in that state instead of maintaining it as your domestic entity — check that state's foreign-qualification requirements once the move is final.
When Do Connecticut's Taxes and Filings Start?
Connecticut's obligations begin on the effective date and time you specify in the Certificate of Domestication (immediately upon filing, or a later date/time you choose under §34-645) — plan your first Business Entity Tax and annual report filings around whichever effective date and time you select.
You'll typically owe a final-year return to your old state covering the period before the domestication took effect, prorated to the conversion date — confirm the exact filing requirement with that state's tax agency, since this varies based on where your prior state was.
Whether Connecticut requires a Certificate of Good Standing from your old state as part of the Certificate of Domestication filing isn't clearly published in the form instructions — check directly with the Secretary of the State's business services division before you file, and have one ready just in case.
How to Move Your LLC to Connecticut Step by Step
If You Do It Yourself
Step 1 — Confirm your LLC is in good standing in its current state.
Connecticut doesn't require this document, but it's still worth confirming your LLC is current before filing.
Step 2 — Get member approval for the move.
Connecticut's approval rule cascades in three layers (§34-643): first, whatever your LLC's own organic rules (operating agreement) specify, if they address domestication; if silent, then whatever your entity's merger-approval rules require; and if both are silent, approval defaults to all interest holders entitled to vote — effectively unanimous. On top of that, any member who would take on new personal liability as a result of the domestication must individually consent, regardless of the general vote threshold, unless they already agreed to that outcome in the governing documents.
Step 3 — File the domestication paperwork.
File with Connecticut Secretary of the State using the Certificate of Domestication, filed with a Connecticut Certificate of Organization, $100 for the Certificate of Domestication, plus Connecticut's public-organic-document (formation) fee for the new Connecticut LLC — roughly $220 total combined; confirm the exact current split with the Secretary of the State.
Step 4 — Confirm your EIN and contracts carry over.
No new EIN is needed. Connecticut's domestication framework (§34-646, "Effect of Domestication") is built around continuity of the same entity, so the IRS treats your EIN as unchanged — update your address with the IRS (Form 8822-B) once your Connecticut registered agent is set. All existing contracts, bank accounts, licenses, and pending liabilities carry over automatically once the domestication is effective — §34-646 establishes that the domesticated LLC continues as the same entity, not a new one stepping into its shoes.
Step 5 — Appoint a registered agent in your new state.
Connecticut calls this role a "Registered Agent" — required before or as part of the domestication filing.
Step 6 — Handle your old state's final obligations.
No. Connecticut's filing doesn't require proof the LLC withdrew from its prior state; that remains a separate obligation under the old state's own law. You'll typically owe a final-year return to your old state covering the period before the domestication took effect, prorated to the conversion date — confirm the exact filing requirement with that state's tax agency, since this varies based on where your prior state was.
Step 7 — Update your tax and compliance calendar.
Connecticut's obligations begin on the effective date and time you specify in the Certificate of Domestication (immediately upon filing, or a later date/time you choose under §34-645) — plan your first Business Entity Tax and annual report filings around whichever effective date and time you select.
Step 8 — Watch for Connecticut-specific domestication traps.
Connecticut is a genuine "domestication" state by name — unlike Colorado, Georgia, California, and Alabama, which all use "conversion" terminology instead. But that shouldn't be mistaken for a simpler process: Connecticut requires an actual separate plan of domestication document (§34-642), not just the certificate that gets filed with the state, and its layered approval rule (organic rules, then merger rules, then unanimous consent, plus individual consent for anyone gaining new personal liability) is one of the more involved approval frameworks in this batch of states.

When Should You Talk to an Attorney About Moving Your LLC to Connecticut?
Talk to an attorney before domesticating your LLC to Connecticut if you need help drafting the formal plan of domestication itself (not just the filed certificate), if any member would take on new personal liability as a result of the move and needs to individually consent, or if your operating agreement is silent on domestication approval and you're unsure which layer of Connecticut's cascading default applies.
Is Connecticut a State Where Domestication Complexity Matters More?
Connecticut is one of the more procedurally formal states for domestication. Unlike most peer states, it requires a genuine, separate "plan of domestication" under §34-642 — not just the filed Certificate of Domestication itself — spelling out the terms of the move, and that plan must be adopted following the layered approval cascade in §34-643 (organic rules, then merger rules, then unanimous consent as the fallback). Any member picking up new personal liability from the move must also individually consent. Given this extra layer of formality, it's worth having an attorney draft or review the plan of domestication itself, not just the certificate that gets filed.
What You Actually Get With LLC Attorney's Connecticut Domestication Service
