Connecticut Certificate of Authority / Guide
Getting a Connecticut certificate of authority, from decision to withdrawal
A foreign corporation gets a Connecticut certificate of authority by filing the Application for Certificate of Authority online for $385 ($40 if it is nonstock), and keeps it by filing an annual report each year at $435 or $50. This guide follows the whole arc in order, with the LLC variation at the end.
Before step one: what you are buying
For the money Connecticut gets, the corporation receives permission to operate in the state, a record on the public register, and a set of duties. There is an annual report at $435 or $50, an agent who has to stay current, and notices when officers, directors or addresses change. The application is a one-time cost. The upkeep is the lasting one.
What sits outside the filing
The authority filing is only one of the places where a Connecticut footprint shows up. Tax registration, payroll and licences are outside what the Secretary of the State handles and outside our filing. The start date of Connecticut work is a legal judgment; a Connecticut business lawyer can tell you which date to use, and once you have settled it, give it to us and we file.
If the corporation is a subsidiary
A subsidiary that does the Connecticut work applies in its own name, as authority is asked entity by entity. The parent is not covered by its subsidiary's certificate. Where a parent also acts here, for example by signing contracts directly, it is a separate question. Keep the corporate chart handy, since you will need to say which entity employs the people and holds the contracts.
What we need from you, and when
At the order, the entity's name, type, home state and the date Connecticut work started. Then the agent's consent and, for an individual, their Connecticut addresses. Before filing, the name of the officer who will approve the application. After filing, an email address that someone reads.
First, the vocabulary
Connecticut uses "foreign" for any business formed outside the state and "domestic" for one formed under Connecticut law. A foreign business that wants to operate here registers. For corporations the registration is a certificate of authority, for LLCs a foreign registration statement. A different document, the certificate of legal existence, is what other states call good standing. It is proof, not permission, and the two are not interchangeable. Keep that distinction in mind while you read the rest.
Decide whether the corporation needs authority
The office's rule is that a business created outside Connecticut must register to do business in Connecticut. Whether a given corporation is doing business depends on its facts. The page on when authority is required covers the statute's grace period of 90 days and its monthly charge of $300.
Set up the filing account first
Connecticut now runs business filing on a new system, and old CONCORD logins do not work, even if the state already holds your email. Start at business.ct.gov, use the Sign in link in the upper corner, then pick Sign up now. You will give your name, an email, a mobile number, a language, a username and a password, pass the human check, and enter the code that arrives by email or text. You may skip the code step. The account is the doorway to every online filing, including the annual report, so create it under an address that will still work in five years.
Gather the corporation facts
You need the exact corporate name from the home-state record, the type of corporation, the state of formation, and the date work in Connecticut started or will start. The application also asks for a six-digit industry code, an address for the confirmation, and, if the corporation's own name cannot be used in Connecticut, an alternative name. A note on the form about a fictitious name covers that case. The form says that leaving out required information gets the document rejected, so a complete set of answers matters more than speed.
Pick the agent
Item 14 of the application offers parts A, B and C, and only one may be used. The candidates are an adult who lives in Connecticut, a business on the state's register that keeps a Connecticut address, or, for a foreign entity, the Secretary of the State. You can serve as your own agent only if you are a Connecticut resident. Swapping agents later runs $50 with shares, $20 without. The agent page compares the options.
File and pay
Create or sign in to a Business.CT.gov account, choose the application, complete it and pay. The state's fee is $385 if it issues shares and $40 if it does not. You can pay for expedited service, $50, at the end if you want it. A paper application is available too, with a check payable to the Secretary of the State, and mail cannot be expedited. We confirm the current fields on the online screens when we prepare your filing.

What the application does not do
It does not turn the corporation into a Connecticut company, it does not license any trade, and it does not by itself produce a certificate of legal existence. It leaves the corporation's governing law and formation date where they were. It adds the right to operate here and the duties that come with it. A domestic corporation, by contrast, is one formed under Connecticut law and files a formation instead.
After approval: the annual report
The annual report is the recurring cost. A stock corporation pays $435, a nonstock one $50. The state sends a reminder about a month before it is due, and the due date shows on the filing page once you log in. The January 1 to March 31 window is for LLCs and LLPs; a corporation reads its date from its own dashboard. A report that goes unfiled can end in dissolution by the office and blocks a certificate of legal existence.
The paper route
The paper application is filled in with ink or typed, with extra 8.5 by 11 sheets attached if a section runs over, and the check is payable to The Secretary of the State. Expedited service is not available by mail, which is one more reason the online route is the default for filings that must be in on time.
Smaller filings along the way
For a stock corporation, an interim notice of a new officer or director is $20, a change of agent $50, a change of business address $50 and a name change $100. A nonstock corporation pays $20, $20, $50 and $20 for the same filings.
Proof of standing for banks
When a lender wants a certificate of legal existence, the office can issue an express or short-form one after the entity has registered and brought its annual report up to date. The short form for a corporation lists all name changes and costs $80; the express form is $50. Verifying a certificate is free when logged in. The office points out that this certificate is not part of starting a business, and it warns about scams that sell it to new owners.
Scams to ignore
Two kinds of unsolicited offer reach new filers. One sells a certificate of legal existence to a business that does not need one to start. The other offers, for a price, to file the annual report. The office tells owners that some such companies are dishonest, says the report is easy to file yourself, and suggests signing in to your own account for deadlines and fraud alerts. If a letter looks official but asks for money, check it against the Business.CT.gov dashboard before paying anything.
A first year in practice
A first year runs in four beats. First decide, gather and apply. Then check the record, note the annual report date and set the reminder email to a shared inbox. File any interim notices if officers change. At the date on your dashboard, file the annual report. The cost of that year is the application plus one report, $820 with shares or $90 without, before agent fees and ours.
Leaving Connecticut
A corporation that stops working in Connecticut files the Application for Certificate of Withdrawal at $0. The state defines the step as ending a registration while the business carries on where it was formed. See the withdrawal page. A corporation still operating should stay authorized, since withdrawal ends the right to operate in the state, and the withdrawal itself is made online.
If the entity is an LLC
An LLC takes a different route: the Foreign Registration Statement, $120, with twelve items and a January to March annual report at $80. The LLC page has the detail. The registered agent options are the same in outline, with the added rule that an LLC cannot appoint itself.
The corporation timeline in state fees
| Moment | Filing | Stock | Nonstock |
|---|---|---|---|
| Before or within the grace period | Application for Certificate of Authority | $385 | $40 |
| Each year | Annual report | $435 | $50 |
| Agent changes | Change of agent | $50 | $20 |
| When work ends | Application for Certificate of Withdrawal | $0 | $0 |
Acting now or waiting for advice
The temptation is to wait until the legal question is settled. The monthly charge argues against waiting: the grace of 90 days runs from the start of business whether or not anyone has made up their mind. A middle course is to apply while the advice is being gathered, since the application is a one-time cost of $385 or $40 and withdrawal is available at $0 if it turns out to be unnecessary.
Records to keep
Keep the filing confirmation, the agent's consent, the home-state proof, the date Connecticut work began and the reasoning behind it, the dashboard login details, and each annual report receipt. If a demand letter ever arrives, those papers answer most of its questions at once.
Dates to diary
| When | What |
|---|---|
| Day 1 of Connecticut work | Start of the 90-day grace |
| Before day 90 | Apply, ideally with days to spare |
| Once a year | Annual report: $435 or $50 |
| On any change | Interim notice, agent change or address change |
| When the work ends | Certificate of withdrawal |
Fixing a mistake costs money
A corrected annual report for a corporation with shares is $100. A name change is $100 or $20, an officer or director who joins costs a $20 notice, and a change of business address is $50 either way. Each correction is a filing of its own with its own fee, so it is cheaper to read the application through before it goes in than to correct it afterwards.
Typical mistakes
Four mistakes cost time. Filing as a stock corporation when the entity has no stock, or the reverse, which changes the fee. Naming a non-resident individual as agent. Treating the certificate of legal existence as the thing to get, when it is a later document. And forgetting that the annual report price is high enough that a dormant corporation costs more in reports than a withdrawal would.
