Connecticut County Business License: Why There Isn't One and What to Do Instead
Connecticut County Business License: Why There Isn't One and What to Do Instead
If you searched for a connecticut county business license, you will not find one, and the search is worth understanding before you spend time or money on it. Connecticut has no county government. Counties were abolished in 1960, so there is no county clerk, no county health department and no county business license. Any site offering a Connecticut county license is selling something that does not exist.
What you need instead is a short sequence of state, town and trade filings. This guide explains what each one is, what it costs based on figures published by the agencies, and where a county-style question actually goes in Connecticut.

Connecticut has no county business license because it has no counties
In many states, a county business license exists because counties run local permitting. Connecticut works differently. The state abolished county government in 1960, and local government is handled by towns and cities. That is why the answer to where a county license is issued is really the town clerk, the town planning and zoning office, and the local health department or health district.
Connecticut also has no general state business license. A state registration is not a license, and a sales tax permit is a tax registration. Here is how the pieces fit together:
- Entity registration: Forming an LLC or corporation with the Secretary of the State through Business.CT.gov. This creates the legal entity. It is a registration, not permission to operate.
- Trade name certificate: Filed with the town clerk, not the state.
- Sales and Use Tax Permit: Issued by the Department of Revenue Services (DRS) to businesses selling taxable goods or services. It is a tax registration.
- Trade licenses: Issued by the agency that regulates your industry, such as the Department of Consumer Protection, the Department of Public Health, the Insurance Department or the Department of Banking.
- Local approvals: Zoning, health and occupancy approvals, issued by your town or local health authority.
What the local units actually are
When a Connecticut business guide says local, it means one of three kinds of body:
- 169 towns and cities. This is where your town clerk, planning and zoning office and building official sit. Most local questions start here.
- 59 local health departments and districts. Some towns run their own health department. Others belong to a multi-town health district. Either way, this is where health approvals are handled. Confirm which one covers your street address before you apply, because a neighboring town may use a different office.
- Nine planning regions. Since 2022 the Census Bureau has reported Connecticut data by these regions, which are councils of governments, in place of the eight historic counties. They do regional planning. They do not issue business licenses, so do not send your paperwork to them.
Mapping the old counties to towns you can search
Many readers still think in terms of counties, so the table below links each historic county to some of its larger towns. The county column is a geography reference only. No county office will accept your filing. Find your own town, then work with its clerk, zoning office and health authority.
| Historic county | Larger towns to start from | Where your local filings go |
|---|---|---|
| Fairfield | Bridgeport, Stamford, Norwalk, Danbury, Greenwich, Fairfield, Stratford, Shelton | The town clerk and town zoning office of your town |
| Hartford | Hartford, West Hartford, New Britain, Bristol, Manchester, East Hartford, Southington, Enfield | The town clerk and town zoning office of your town |
| Litchfield | Torrington, plus smaller towns that often use a regional health district | The town clerk and town zoning office, then the health district that serves your town |
| Middlesex | Middletown | The town clerk and town zoning office of your town |
| New Haven | New Haven, Waterbury, Hamden, Meriden, West Haven, Milford, Wallingford | The town clerk and town zoning office of your town |
| New London | New London, Norwich, Groton, Waterford | The town clerk and town zoning office of your town |
| Tolland | Vernon, Tolland, Ellington | The town clerk and town zoning office of your town |
| Windham | Windham (Willimantic), Killingly, Putnam | The town clerk and town zoning office of your town |
What to do instead: the filing sequence
Work through these steps in order. The first three are state filings, step 4 is a town filing, the next two are tax and trade items, and the last two are local approvals and recurring obligations.
- Check and, if needed, reserve your name. Search the business records on Business.CT.gov, which is free. An LLC name must contain Limited Liability Company or an abbreviation such as LLC or L.L.C., and it must be distinguishable on the record from names already registered or reserved. If you need time to finish your paperwork, a name reservation costs $60 and lasts 120 days.
- Form the entity. An LLC files a Certificate of Organization (Domestic Limited Liability Company) for $120. A corporation files a Certificate of Incorporation (Domestic Stock Corporation) for $250, followed by the Organization and First Report at $150. Most online filings are accepted automatically, so the state says expedited service is usually unnecessary. Expedited review costs $50 per transaction, is completed within 24 hours of receipt, and is available only for filings made online. The Secretary of the State does not publish a standard turnaround time for ordinary filings, so check the status in your Business.CT.gov account.
- Appoint a registered agent. Every LLC and corporation must maintain a registered agent who receives legal and official correspondence. The agent must be either a Connecticut resident at least 18 years old or a business entity registered with the Secretary of the State. The agent's address must be a usual place of business in Connecticut that is customarily open during normal business hours with an authorized person present. A post office box or commercial mailbox does not qualify.
- File a trade name certificate if you operate under a name other than your legal name. The certificate is filed with the town clerk of the town where the business is primarily transacted. The fee is $20 payable to that town clerk. Do not send it to the Secretary of the State.
- Get a Sales and Use Tax Permit if you sell taxable goods or services. DRS charges a $100 registration fee. You must display the permit at each location. The state sales tax rate is 6.35%. Start at the DRS sales tax information page listed below.
- Identify any trade license you need. Connecticut has no single state business license, so licensing depends on your industry. Use the Business.CT.gov New Business Checklist and the eLicense system to find the agency that regulates your work. Fees and processing times vary by license, so confirm both on that agency's page before you budget.
- Obtain local approvals. Depending on your use, you may need zoning approval, a health approval from your local health department or district, and an occupancy approval. Connecticut does not publish one timeline for these. Ask each office what it requires and how long it takes.
- Calendar your annual report. Both LLCs and corporations file an Annual Report with the Secretary of the State every year. The LLC fee is $80 and the corporation fee is $150. Business.CT.gov shows each entity its own next due date in its account rather than one statewide deadline, although widely reported practice for LLCs is a January 1 to March 31 window. Your registered agent information is confirmed and updated when you file.
Questions to ask your town and health office
Local fees and timelines are set by each municipality or health district, so this guide does not state them. Use the questions below when you call or visit.
| Approval | Who usually handles it | What to ask |
|---|---|---|
| Zoning approval | Town planning and zoning office | Is my use allowed in this zone? Is a special permit, site plan or home occupation approval needed? Check the fee and timeline with the town. |
| Health approval | Local health department or health district | Which office covers my address? What does a food, personal service or other operation at this address require? Check the fee and timeline with that office. |
| Occupancy or building approval | Town building official | Does a change of use or a new tenant require a certificate of occupancy? Check the fee and timeline with the town. |
| Trade name certificate | Town clerk | The filing fee is $20. Ask the clerk whether your town requires anything else for the filing. |
Tax items to understand at formation
Tax treatment affects which entity you choose and what you owe, so review these points before you file.
- LLCs: Connecticut has no franchise tax or annual privilege tax on LLCs. An LLC taxed as a partnership or S corporation may elect the optional Pass-Through Entity Tax with DRS. The election is made each year and is irrevocable for that year.
- LLCs taxed as corporations: These pay the Corporation Business Tax of 7.5% of apportioned net income, with a $250 minimum. They also pay a capital base tax that is being phased out: 0.16% for 2026, 0.11% for 2027, and none from 2028 (CGS 12-219). Companies with total income of $100 million or more, or that file in a combined unitary group, also pay a 10% surtax.
- Personal income tax: Owners who receive business income on their personal returns face Connecticut's progressive personal income tax, which has seven brackets ranging from 2% to 6.99%.
Check with a CPA before you choose a tax election. The thresholds and phase-out schedule above are the figures the state publishes, but your federal and state results depend on your facts.
Common mistakes that cost time
- Searching for a county license. Connecticut has no county licensing office. Spend that time on the town clerk, the zoning office and the trade agency instead.
- Filing the trade name with the Secretary of the State. Trade name certificates go to the town clerk of the town where you primarily do business.
- Using a post office box for the registered agent address. The agent address must be a usual place of business in Connecticut where an authorized person is present during normal hours.
- Assuming entity registration covers your industry. A certificate of organization lets you form the company. It does not authorize you to work in a regulated trade.
- Skipping the annual report. It is required every year for both LLCs and corporations, and the due date is set in your Business.CT.gov account.
When to get professional help
A simple single-owner service business can often be handled with the steps above. Bring in a qualified professional if you have several owners and need an operating agreement, if you are choosing between an LLC and a corporation, if you plan to elect pass-through treatment, or if your industry requires a regulated trade license with conditions. An attorney can advise on entity structure and contracts. A CPA can advise on tax elections and filings. The Connecticut Small Business Development Center (CTSBDC) and the SBA's Connecticut district office are also useful starting points for questions about running a business in the state.
