LLC Formation in Connecticut — Filing, Reports and Taxes

The structure you choose today affects taxes and liability for years. This guide to LLC formation in Connecticut explains the filing, the ongoing reports and the taxes that apply, with flat fee pricing.

In Connecticut, you form an LLC by filing a Certificate of Organization with the Connecticut Secretary of the State. Furthermore, connecticut LLCs file an annual report. Therefore, planning for ongoing obligations matters as much as the filing itself.

Our attorneys form Connecticut LLCs and draft operating agreements at fixed prices, entirely online.

Filing your Connecticut LLC

Connecticut LLCs are formed by filing a Certificate of Organization with the Connecticut Secretary of the State, usually online. State fees change from time to time, so confirm the current amount when you file.

You must appoint a registered agent with a physical address in Connecticut. In addition, the name must include "LLC" or a similar designation and be distinguishable from existing names. Our LLC Formation service, from $99, handles the filing and checklist.

Ongoing reports in Connecticut

Connecticut LLCs file an annual report. Missing a required filing can lead to penalties and, eventually, dissolution.

Our annual report filing service tracks and files your reports. As a result, your LLC stays in good standing without extra effort.

Connecticut taxes for LLCs

Connecticut has a state income tax and an elective pass-through entity tax. By default, a single-member LLC is taxed like a sole proprietorship, and a multi-member LLC like a partnership. Therefore, profits usually pass through to the owners' personal returns.

Connecticut repealed its business entity tax for tax years starting in 2020. As a result, ongoing costs for small LLCs are lower than they once were.

Your Connecticut operating agreement

Filing creates the LLC, but the operating agreement decides how it works. Without one, Connecticut's default rules apply, and they may not match your deal.

A strong agreement sets ownership percentages, contributions, profit allocations and voting rules. Moreover, it plans for exits such as death, divorce or a member who wants out. A buy-sell agreement can add detail on valuation and payment. Our LLC Operating Agreement service drafts a Connecticut-ready agreement, starting at $79.

LLC or corporation in Connecticut?

Most small businesses in Connecticut choose an LLC for its flexibility and simple taxes. Moreover, an LLC can elect S corporation tax treatment if it qualifies, which can reduce self-employment tax for profitable businesses.

However, startups seeking venture capital usually need a C corporation, often formed in Delaware and registered in Connecticut. Consequently, compare both before filing. Our business formation consultation walks through the trade-offs, and our corporation formation service sets up corporations when needed.

Your first month after forming a Connecticut LLC

Next, obtain an Employer Identification Number from the IRS. It is free and usually issued online the same day. Then open a business bank account in the LLC's name, so business and personal money stay separate.

After that, register for state taxes where required and check city or county licensing. Moreover, if you hire employees, register for unemployment insurance and payroll withholding. Finally, sign your operating agreement and store it with your formation documents.

Protecting your liability shield in Connecticut

An LLC protects your personal assets only if you treat it as a separate business. Courts in Connecticut, like courts elsewhere, can disregard the LLC in serious cases of abuse.

Therefore, sign contracts in the LLC's name, keep business money in a business account and keep the LLC adequately funded. In addition, carry appropriate insurance, because an LLC does not protect you from your own negligence. If you operate in other states, our foreign qualification service registers you there.

Common Connecticut LLC mistakes

The most common mistake is missing a state filing or tax deadline. Another is skipping the operating agreement, which leaves default rules in place.

Similarly, owners sometimes forget to update the Connecticut Secretary of the State when addresses or managers change. Consequently, important notices go astray. Therefore, review your LLC's records at least once a year.

Choosing a name and registered agent in Connecticut

Search the state database before filing to confirm your name is available. In addition, check that a matching domain name is free. A name search is not a trademark search, so consider a trademark search before investing in branding.

Your registered agent must have a physical Connecticut address and be available during business hours. Many owners use a professional agent for privacy, because the agent's address appears in public records instead of their home.

Do you need a lawyer to form an LLC in Connecticut?

Connecticut does not require a lawyer to form an LLC. However, the filing is the easy part. The operating agreement, tax choices and ongoing compliance are where mistakes happen.

Attorney-prepared formation gives you a fixed price and documents that fit your situation. As a result, partners know where they stand, and the LLC is set up to protect you from the start. If you are unsure which structure fits, a business formation consultation explains the options for Connecticut.

Changing, adding members or closing your Connecticut LLC

Businesses change over time. For example, you may add a partner, change managers, move the office or rename the company. Most changes require an amendment filed with the Connecticut Secretary of the State. Similarly, the operating agreement should be updated to match.

Adding or removing members also has tax consequences. Therefore, plan the change with your accountant. If the business ends, file the required dissolution documents and settle debts properly. Otherwise, fees and reports may continue to accrue. Our dissolution filing service handles the closing steps.

Licenses and permits for a Connecticut LLC

Forming the LLC does not license the business. Depending on what you do, you may need state professional licenses, a sales tax permit, and city or county business licenses. For example, contractors, salons and food businesses often need specific permits.

Therefore, check requirements with Connecticut agencies and your local government before opening. Consequently, you avoid fines and interruptions after launch.

Single-member vs. multi-member LLCs in Connecticut

A single-member LLC has one owner and is simple to run. However, a written operating agreement still helps prove the LLC is separate from you.

A multi-member LLC files a federal partnership return by default, and each member receives a Schedule K-1. Moreover, its operating agreement must cover voting, profit sharing and exits in detail. For the national picture, read our national guide to LLC formation and corporate structuring.
