Best LLC Services in Connecticut for 2026: 6 Providers Compared

The best Connecticut LLC service should do more than submit a form. It should make the price clear, explain what is included, and help you manage the state-specific details that matter after approval. Northwest Registered Agent is our top choice overall, while Bizee offers the lowest entry price and Harbor Compliance is the strongest premium option for broader compliance needs.

Connecticut LLC Services Compared

Connecticut charges $120 to file a domestic Certificate of Organization. Every price below is a provider service price, so the state filing fee is added unless a checkout page clearly says otherwise. We also separated included features from optional add-ons because a $0 or low-cost package may not include an operating agreement, EIN assistance, or agent coverage.

Prices and package details were checked in July 2026 against the providers’ current formation or membership pages. Promotions, renewals, and checkout options can change, so read the final order before paying.

How We Tested These Providers in Connecticut

We reviewed six national formation companies using the same criteria: base price, add-on transparency, agent coverage, operating agreement and EIN availability, processing options, customer support, privacy value, and ongoing compliance tools. Package information came from each provider website, while customer ratings were treated as supporting context rather than proof that a package is suitable for everyone.

We also reviewed recent customer feedback from independent platforms to identify recurring comments about support, billing transparency, and ease of use, although ratings were not used as the sole basis for our rankings.

Connecticut-specific usefulness also affected the rankings. A provider earned more credit when it clearly separated its own price from the $120 state fee, addressed the agent requirement, and offered practical help with the annual report. We did not assume that a higher-priced bundle was automatically better. Features only improved a score when they reduced work or solved a realistic need for a Connecticut owner.

The 6 Best LLC Services in Connecticut

1. Northwest Registered Agent: Best Overall

Northwest earns the top position because its $39 package includes formation filing, one year of registered agent service, an operating agreement, and access to its Corporate Guides. It also includes business identity tools such as a domain, email, phone line, and address. Those extras are more useful than generic marketing add-ons for someone working from home or forming from outside Connecticut.

Price: $39 plus the state filing fee
Best for: Owners who value privacy, a business address, and access to knowledgeable support

The privacy benefit is particularly relevant here. Connecticut requires an agent with an in-state physical address, and third-party coverage can keep a home address from serving as the public contact point. Northwest states that renewal costs $125 per year, which makes the ongoing expense easier to evaluate before ordering.

The main limitation is that EIN filing is not part of the base package. Owners who can apply directly with the IRS may not see that as a drawback, but anyone seeking a single all-inclusive order will need an add-on or another provider.

2. Bizee: Best Low-Cost Option

Bizee’s Basic package handles the formation submission without a service charge, leaving the Connecticut fee as the unavoidable starting cost. That makes it appealing to owners who are comfortable obtaining an EIN, preparing internal records, and managing later obligations themselves.

Price: $0 plus the state filing fee
Best for: A straightforward filing with minimal provider cost

The tradeoff is package complexity. Bizee’s current LLC page says agent coverage ranges from three to twelve months depending on the package, while its operating agreement and EIN features sit above the basic tier. The Standard and Premium choices add useful components, but the value changes once those upgrades are selected. Compare the complete checkout total rather than judging Bizee only by the $0 headline.

Bizee also provides an online dashboard and compliance alerts. These can help a first-time owner keep documents organized, but alerts are not the same as having the annual report prepared and submitted. Confirm which tasks remain your responsibility and note the renewal price for any continuing coverage before finishing the order.

3. ZenBusiness: Best Guided Experience

ZenBusiness has a cleaner progression than many formation sites. Starter covers the core submission, Pro adds an operating agreement, EIN, rush handling, templates, and compliance tools, and Premium adds first-year registered agent coverage. That structure makes it easier to choose based on the amount of help needed.

Price: $0 for Starter, $199 per year for Pro, or $399 per year for Premium, plus the state fee
Best for: First-time owners who prefer a guided dashboard and bundled setup tools

The strongest fit is someone who wants more guidance after the Certificate of Organization is accepted. Pro includes several commonly requested tasks in one package, but its annual pricing means the long-term cost matters more than the first checkout. Starter is less expensive, although the missing agreement, EIN, and agent coverage can lead to separate purchases.

Premium is the only tier that includes first-year agent service. Pro may still be a reasonable choice for a resident serving as their own agent, while a home-based owner seeking a third-party address should compare Premium against Northwest’s lower formation price and stated renewal.

4. Harbor Compliance: Best Premium Compliance Support

Harbor Compliance is less focused on being the cheapest route and more focused on managing filings across a company’s lifecycle. Its formation service starts at $99, tracks the submission through approval, and can connect with separate agent, annual report, licensing, tax registration, and entity-management services.

Price: From $99 plus the state filing fee
Best for: Growing, regulated, or multistate organizations with more than a basic formation need

That scope is valuable when the new entity will hire employees, operate in a regulated industry, or expand into other states. The provider’s compliance tools can identify additional registrations and centralize deadlines. A simple single-member company that only needs the Certificate of Organization may not receive enough extra value to justify building a larger Harbor package.

Agent service, EIN work, and later filings should be treated as separate selections rather than assumed inclusions in the $99 starting price. Harbor is our premium choice because of its broader compliance capability, not because the entry package contains every startup document.

5. LegalZoom: Best for Legal Add-Ons

LegalZoom’s Basic package covers the formation document and name check without a provider charge. Pro adds an operating agreement, EIN, legal-document access, e-signatures, and a temporary attorney-plan benefit. Premium builds on Pro with bookkeeping tools.

Price: $0 for Basic, $249 for Pro, or $299 for Premium, plus the state fee
Best for: Owners who expect to use legal documents or attorney-access features

The comparison point is not simply Basic versus another free package. LegalZoom becomes more distinctive at Pro, where the legal-document library and consultation access can support owners dealing with contracts, hiring, or other matters beyond formation. Those benefits are optional conveniences, not Connecticut requirements.

Review every subscription disclosure carefully. Certain plan benefits continue as paid services unless canceled, so the cost after the included period can matter more than the package price. Its agent service is also separate. LegalZoom works best when its legal ecosystem will be used; it is harder to justify when the only objective is submitting the Certificate of Organization.

6. Rocket Lawyer: Best for Ongoing Legal Documents

Rocket Lawyer approaches formation through its membership platform. The current annual plans start at $149, and the first business registration is included, excluding government charges. Membership also provides personalized documents, e-signatures, legal reminders, and different levels of access to a Legal Pro.

Price: First registration included with a paid membership; later registrations are $99 plus state fees
Best for: Owners who will regularly create contracts or ask legal questions

This structure is attractive when the company will use agreements, contractor forms, document review, or recurring legal support. It is less compelling for a one-time filing because the apparent $0 registration depends on paying for a membership. EIN assistance and registered agent service are separately priced, with the latter listed at $125 per year on eligible plans.

Rocket Lawyer ranks sixth because its value depends heavily on continued use. A founder who needs ongoing documents may save time through the membership, while someone seeking only formation can find a lower total elsewhere.

Do You Need a Formation Service in Connecticut?

No service is legally required. You can create an account on Business.CT.gov, prepare the Certificate of Organization, pay the $120 fee, and manage later filings yourself.

DIY makes sense when the ownership and management structure are simple, a Connecticut resident can serve as agent, and you are comfortable tracking deadlines. A paid provider becomes more useful when you want document preparation, a commercial address, agent coverage, or continuing reminders. It may also save effort when forming from outside the state or coordinating several registrations.

Connecticut calls the appointee an agent or statutory agent in its formation materials, although providers commonly sell the role as registered agent service. An individual agent must generally be a Connecticut resident age 18 or older. A qualifying entity registered with the state and having a Connecticut address may also serve. Home-based owners can compare Connecticut registered agent services before deciding whether to list themselves.

How Much Does an LLC Cost in Connecticut?

The required formation expense is the $120 Certificate of Organization filing fee. Provider prices are added to that amount, while agent coverage, EIN assistance, expedited handling, and document packages may raise the total. Connecticut’s official domestic LLC fee schedule also lists an $80 annual report fee.

How to Form an LLC in Connecticut

Connecticut’s online process is manageable, and a provider mainly changes who prepares and submits the information. Each step below is only a summary.

1. Check the Name
   Choose a distinguishable legal name that satisfies Connecticut’s naming rules. Use the Connecticut business entity search before committing to it.
2. Appoint an Agent
   Name an eligible Connecticut resident or qualifying entity that can receive official and legal documents. Owners wanting a commercial address can hire an agent rather than serving personally.
3. File the Certificate of Organization
   Submit the Certificate of Organization through the Secretary of the State’s Business.CT.gov portal and pay $120. Processing depends on the submission and any available expedited option, so check the current Connecticut LLC approval timeline before setting a launch date.
4. Prepare an Operating Agreement
   Keep an internal agreement describing ownership, management authority, voting, distributions, and departure procedures. The Connecticut operating agreement guide explains what this document can cover.
5. Obtain an EIN and Complete Other Registrations
   Apply after the entity has been formed. The IRS issues EINs at no charge through its official EIN application information, although a provider may charge to handle the application. Our Connecticut EIN guide walks through the available methods.
