Starting a Business in Connecticut (2026): Licenses, Permits & Requirements
Connecticut is the second-richest state in the United States by per-capita personal income — and it shows in the operating environment. Three structural realities define starting a business in Connecticut in 2026 more than anywhere else in the Northeast: no county government anywhere in the state (CT abolished county government in 1960; all local permitting runs through 169 town and city halls), indexed annual minimum-wage increases (Public Act 19-4 ties the rate to the federal Employment Cost Index — the 2026 minimum wage is $16.94/hour, second-highest in the nation behind Washington’s $17.13), and a graduated income tax with seven brackets running 2% to 6.99% with a 2% Phase-Out Add-Back and tax-benefit recapture mechanism unique to CT and New York.
The good news: Connecticut’s structural compliance overhead is concentrated in a handful of agencies, not scattered across dozens. The Department of Consumer Protection (DCP) is the umbrella for HVAC, plumbing, electrical, home improvement, cosmetology, and real estate licensing. The Office of Early Childhood (OEC) handles all daycare. The Department of Energy and Environmental Protection (DEEP) covers pesticide applicators. The Department of Emergency Services and Public Protection (DESPP) licenses private investigators. The Department of Revenue Services (DRS) administers the 6.35% flat sales tax (one of the simplest sales-tax structures in the Northeast — no local sales taxes anywhere in CT). And LLC formation runs through one portal at business.ct.gov for $120.
The bad news: a tightly indexed minimum wage, the only state-administered Paid Family and Medical Leave program in southern New England, the new Paid Sick Leave expansion under PA 24-8 (which dropped the coverage threshold to 11+ employees on January 1, 2026, and expands to all employers on January 1, 2027), and CT’s CGS § 31-275 workers’ compensation rule that triggers at the very first employee — combined — make Connecticut one of the higher-effort payroll states in the country for businesses with even modest headcounts. Plan around the headcount thresholds; budget for the payroll stack.

How to Start a Business in Connecticut (Step by Step)
Step 1: Choose Your Business Structure
Connecticut recognizes the standard set of business structures. The right choice depends on liability exposure, tax treatment, and how you plan to grow:
- Sole Proprietorship — No state filing required (just a Trade Name with the town clerk if operating under a name other than your own). Owner is personally liable for all business debts. Default for a first-time freelancer or single-person operator.
- LLC (Limited Liability Company) — The default choice for most CT small businesses. Personal asset protection, flexible tax treatment, $120 to form, $80/year ongoing. Default tax treatment is pass-through, so business income flows to owners’ personal returns.
- S-Corporation — Can reduce self-employment taxes for profitable operating businesses. Requires forming a CT corporation first, then electing S-corp status with the IRS. Subject to CT’s optional Pass-Through Entity Tax at 6.99% (elective since 2024).
- C-Corporation — Subject to Connecticut’s Corporation Business Tax at 7.5% (8.25% on income over $100M) plus the 10% surtax on companies with $100M+ gross proceeds (extended through 2029). Better for businesses planning outside investment, ESOPs, or share issuance.
- Partnership — General partnership (GP), limited partnership (LP), or limited liability partnership (LLP). LP and LLP filings go through the Secretary of the State.
For most Connecticut small businesses starting out, an LLC is the right structure. The $120 formation cost is moderate (lower than New York’s $200, much lower than Massachusetts’s $500), the $80/year annual report is one of the lower recurring fees in the Northeast, and the personal-asset protection plus pass-through taxation gives flexibility as the business grows.
Step 2: Form Your Business at business.ct.gov
LLC Formation via Connecticut Secretary of the State
All Connecticut business entities are filed through the Secretary of the State, Commercial Recording Division. Online filings are processed at business.ct.gov:
| Filing | Cost | Notes |
|---|---|---|
| Certificate of Organization (Domestic LLC) | $120 | One-time formation fee |
| Foreign LLC Registration | $120 | For out-of-state LLCs operating in CT |
| LLC Annual Report | $80 | Due January 1 – March 31 every year |
| Articles of Incorporation (Stock Corporation) | $250 minimum | Plus organization tax of $0.01 per share over 20,000 |
| Corporation Annual Report | $50-$435 | Tiered; LLC fee is flat $80 |
| Reserve a Business Name | $60 | 120-day reservation |
How to file your LLC online:
- Create an account at business.ct.gov
- Search the business name database to confirm availability — the name must include “Limited Liability Company,” “L.L.C.,” or “LLC”
- File your Certificate of Organization ($120) — designate a registered agent with a physical Connecticut street address
- Online filings are typically processed within 1-3 business days; expedited processing is available for an additional fee
Annual Report — Uniform January 1 to March 31 Window
Connecticut LLCs file an Annual Report every year between January 1 and March 31. Unlike most states (which use the entity’s anniversary date), CT uses a single uniform window — every CT LLC, regardless of formation date, files in the same Q1 window. The fee is $80. File online at business.ct.gov. Failure to file can result in administrative dissolution.
Operating Agreement
Connecticut law does not require an LLC operating agreement, but it is strongly recommended. The agreement defines member rights, profit distribution, management structure, voting, and dissolution procedures. Keep it with your business records — it does not need to be filed with the state.
Trade Name (DBA) — 5-Year Expiration as of January 1, 2025
If your business operates under a name different from its registered legal name, you must file a trade name certificate with the town clerk in the town where your business is primarily conducted. Important change: as of January 1, 2025, trade name certificates expire 5 years after filing and must be renewed. The fee is approximately $10-$20 depending on the municipality. Track your renewal date — older trade names that haven’t been refiled may be lapsing in 2030.
Federal EIN
Apply for a free EIN at IRS.gov. Issued instantly online. Required to open a business bank account, hire employees, and file most tax forms.
Step 3: Get Required Licenses and Permits
No Statewide General Business License
Connecticut has no statewide general business license — there is no single “Connecticut business license” you apply for. However, many municipalities require local business permits or licenses. Because Connecticut has no county government, all local permitting goes through the city or town clerk. The 169 distinct town/city halls each have their own permit menus. Check your specific municipality:
- Bridgeport (largest city) — Business licenses through the City Clerk’s Office
- New Haven — Business licenses through the City Clerk; food trucks through Health Department
- Hartford (state capital) — Business licenses and permits through the Permits Office and Hartford Health Department
- Stamford (Fairfield County) — Business licenses through the City Clerk; Stamford Health Department for food
- Waterbury, New Britain, Norwalk, Danbury — Town/city clerk for trade name and local permits
Industry-Specific Professional Licenses
Connecticut concentrates professional licensing across five primary state agencies. Match your industry to the right one:
- Department of Consumer Protection (DCP) — HVAC, plumbing, electrical contractors; Home Improvement Contractor (HIC) registration; real estate; pharmacy; drug control. The largest trades-licensing umbrella.
- Office of Early Childhood (OEC) — daycare licensing under CGS § 19a-77+ for Family Child Care Homes, Group Child Care Homes, and Child Care Centers. Care 4 Kids subsidy administration.
- Department of Public Health (DPH) — Hairdresser/Cosmetician, Nail Technician, and Eyelash Technician licensing under CGS Chapter 387 (§§ 20-250+); food service permits delegated to 71 local health departments + 19 health districts; certain health-related professions.
- Department of Energy and Environmental Protection (DEEP) — pesticide applicator certification under CGS § 22a-54; landscape spraying; environmental compliance.
- Department of Emergency Services and Public Protection (DESPP) — Special Licensing and Firearms Unit licenses private investigators, security guards, alarm installers, and pistol permits under CGS § 29-153+.
Home Improvement Contractor (HIC) Registration
Connecticut requires Home Improvement Contractor (HIC) registration for any business performing work on residential property — including HVAC, electrical, plumbing, landscaping with hardscape, cleaning services with repairs, painting, roofing, and similar trades. Registration through DCP under CGS § 20-419+:
- HIC fee: $220 for a 2-year period
- Per-business registration: registers the entity, not individual employees
- No bond requirement: CT does not require a contractor surety bond for HIC
- Penalty for non-registration on residential work: contracts may be unenforceable, lien rights may be void under CGS § 20-429
Step 4: Register for State Taxes
Connecticut Income Tax — Seven Brackets, 2% to 6.99%
Connecticut has a graduated individual income tax with seven brackets. The 2024 tax cut (Public Act 23-204) reduced the bottom two marginal rates to 2% and 4.5%, where they remain for tax year 2026:
| Single Filer Income | Married Filing Jointly | Rate |
|---|---|---|
| $0 – $10,000 | $0 – $20,000 | 2.0% |
| $10,001 – $50,000 | $20,001 – $100,000 | 4.5% |
| $50,001 – $100,000 | $100,001 – $200,000 | 5.5% |
| $100,001 – $200,000 | $200,001 – $400,000 | 6.0% |
| $200,001 – $250,000 | $400,001 – $500,000 | 6.5% |
| $250,001 – $500,000 | $500,001 – $1,000,000 | 6.9% |
| Over $500,000 | Over $1,000,000 | 6.99% |
Connecticut’s PIT is more complex than most states because of two unique add-back mechanisms. The 2% Phase-Out Add-Back recaptures the benefit of the 2% rate for moderate earners — beginning at $56,500 CT AGI for single filers (max $250 add-back) and $100,500 for MFJ (max $500). And the tax-benefit recapture applies to high earners, requiring them to pay the top 6.99% on all income (not just amounts above $500K single / $1M MFJ). Personal exemptions: $15,000 (single, phasing out above $30,000 CT AGI to $0 by $44,000); $24,000 (MFJ, phasing out above $48,000 to $0 by $71,000); $19,000 (Head of Household); $12,000 (married, both earning).
Connecticut Sales Tax — Flat 6.35% Statewide, NO Local Sales Tax
Connecticut’s sales tax is a flat 6.35% — and that is the only rate you collect anywhere in the state. CT is one of a small number of states with NO local sales tax. Compare to neighboring New York (state 4.0% + NYC 4.5% + MCTD 0.375% = 8.875%), Massachusetts (6.25% with local meals tax adders), and Rhode Island (7%). The simplicity is a real operating advantage:
- State sales tax rate: 6.35% (uniform statewide)
- No local sales taxes: Connecticut law does not authorize local sales tax
- Higher rate on luxury goods: 7.75% on motor vehicles over $50,000, jewelry over $5,000, and clothing/footwear items over $1,000
- Higher rate on prepared meals + beverages: 7.35% sales tax on prepared meals and certain beverages
- 1% room occupancy / hotel tax: in addition to the 15% Room Occupancy Tax administered separately
- Sales Tax Permit: $100 fee to register (valid 2 years, auto-renewed while account is active); register at myconneCT via the REG-1 application
- Filing frequency: Monthly, quarterly, or annual depending on tax liability
- Services: Connecticut taxes only specifically enumerated services (window cleaning, janitorial, landscaping, computer services, others) — many service businesses (salon labor, basic personal services) are NOT taxable; check DRS guidance for your industry
Corporate Income Tax — 7.5% Plus 10% Surtax Through 2029
Connecticut imposes a Corporation Business Tax on C-corporations:
- 7.5% on net income up to $100 million
- 8.25% on net income over $100 million
- 10% surtax on companies with $100 million+ gross proceeds (or filing as part of a combined unitary group), extended through 2029
- $250 minimum tax regardless of income
Pass-Through Entity Tax (PTET) — Now Elective Since 2024
Connecticut became the first state to enact a Pass-Through Entity Tax (PTET) in 2018 as a workaround for the federal SALT cap. Critical change: PTET became elective in 2024 (it was previously mandatory for all PTEs). The rate is 6.99% at the entity level. To elect, file the election with each year’s return. PTEs that pay the elective tax provide owners a credit for state taxes paid — preserving the federal deduction at the entity level instead of the owner level.
Employer Taxes — UI, PFML, Paid Sick Leave
Register for employer tax accounts through myconneCT:
- Unemployment Insurance (UI) Tax: 2026 wage base is $27,000 (up from $26,100 in 2025). New-employer rate dropped to 1.9% (down from 2.2% in 2025). Experience-rated rates after Year 4 range from 1.1% to 9.9%. CT applied a 1.125 rate-reduction divisor in 2026 to soften the wage-base increase. Public Acts 21-200 and 22-67 set the UI Trust Fund solvency framework.
- State Income Tax Withholding: Register through DRS to withhold CT state income taxes from employee paychecks. Use Form CT-W4.
- CT Paid Family and Medical Leave (CT PFML): 0.5% of wages — employee-only, no employer match. 2026 cap = federal Social Security wage base ($184,500), max contribution $922.50 per employee per year. Maximum weekly benefit $1,016.40 (60x state minimum wage). Employer remits, employee bears the cost. Register at ctpaidleave.org.
- Connecticut Paid Sick Leave (PA 24-8): coverage threshold dropped to 11+ employees on January 1, 2026 and expands to ALL employers (1+ employee) on January 1, 2027. Accrual at 1 hour per 30 hours worked, up to 40 hours per year. The “service worker” concept that limited the prior law was eliminated as of January 1, 2025 — covered employers must provide sick leave to all employees, with limited exceptions for “seasonal employees” (≤120 days/year).
Report new hires to the Connecticut New Hire Reporting Center within 20 days of hire date under CGS § 31-2c.
Step 5: Get Business Insurance
Workers’ Compensation — Mandatory at the First Employee
Connecticut requires workers’ compensation insurance for any employer with one or more employees under CGS § 31-275. There is no minimum-employee threshold (unlike Florida’s 4-employee threshold or Texas’s optional WC). Coverage is provided through the private insurance market — Connecticut has no monopolistic state fund. The CT Workers’ Compensation Commission (WCC) oversees compliance.
| Status | Workers’ Comp Required? |
|---|---|
| 1 or more employees (W-2) | Mandatory |
| Sole proprietor / single-member LLC, no employees | Not required (may elect) |
| Domestic workers (≥26 hours/week in private home) | Required under CGS § 31-275(10) carve-out |
| Independent contractors (genuinely 1099) | Not required for true ICs; misclassification risk applies |
Penalties for failure to carry coverage include fines, stop-work orders, and personal liability for any work-related injuries. CT applies the IRS-style 20-factor test plus state-specific factors to challenge worker classification — agriculture and construction are heavily audited.
General Liability Insurance
While not always legally mandated, general liability insurance is essential. Most clients, contracts, and licensing boards (including the HIC registration) require proof of coverage. Industry standard: $1 million per occurrence / $2 million aggregate. Premium ranges $400-$3,000+/year for most small businesses depending on industry and revenue.
Connecticut-Specific Costs and Quirks Most New Operators Miss
The Indexed Minimum Wage Compounds
Connecticut’s $16.94/hour minimum wage in 2026 is the second-highest in the United States, behind only Washington’s $17.13. Public Act 19-4 indexes the rate annually to the U.S. Department of Labor’s Employment Cost Index — meaning the minimum wage will keep rising for the foreseeable future, regardless of legislative action. The 2026 increase was 3.6% ($0.59) from 2025’s $16.35. Plan compensation budgets accordingly; CT’s labor cost premium over neighboring NY ($16.50 statewide) and RI ($15.00) is real and durable.
Tipped-Wage Math Gets Granular
Connecticut maintains the tipped wage but separates it for waitstaff vs. bartenders under CGS § 31-60:
- Hotel/restaurant waitstaff: $10.71/hr cash wage + max $6.23/hr tip credit = $16.94 total minimum
- Bartenders: $13.81/hr cash wage + max $3.13/hr tip credit = $16.94 total minimum
- All other employees: $16.94/hr (no tip credit)
Employers must inform employees of the tip credit before claiming it and ensure cash wage + tips reach $16.94/hour. Insufficient tips = employer makes up the difference.
The 169 Town Halls Permit Wall
Connecticut has 169 distinct municipalities (cities and towns) and no county government since 1960. Every local building permit, food permit, mobile vendor license, parking variance, and zoning approval comes from the town hall — not a centralized county office. Operating across multiple CT towns means multiple permit applications, multiple fee schedules, multiple inspector relationships, and multiple political environments. A food truck running between Hartford and Stamford will pull permits from both health districts.
CT PFML Is Among the More Generous in the US
The Connecticut Paid Family and Medical Leave program offers up to 12 weeks of paid leave in a 12-month period plus an additional 2 weeks for serious health conditions related to pregnancy. Maximum weekly benefit is $1,016.40 in 2026 (capped at 60x the state minimum wage of $16.94). The 0.5% employee-only payroll tax is a modest contribution relative to the benefit replacement. Funding starts Day 1 of employment.
Paid Sick Leave Is Now Almost Universal
Connecticut was the first state in the US to enact paid sick leave (Public Act 11-52 of 2011) — and PA 24-8 of 2024 dramatically expanded it. The phase-in:
- January 1, 2025 — employers with 25+ employees
- January 1, 2026 — employers with 11+ employees ← currently in effect
- January 1, 2027 — ALL employers with 1+ employee
For small operators (1-10 employees), 2027 is the full-coverage year. The “service worker” concept that limited the original 2011 law was eliminated as of January 1, 2025 — when you become covered, you provide sick leave to all employees, not just service workers. Plan accrual systems before your headcount crosses the threshold.
HIC Trap for Out-of-State Contractors
Out-of-state contractors expanding into CT (especially HVAC, plumbing, electrical, landscaping, painting, roofing) routinely miss the Home Improvement Contractor (HIC) registration. Holding a state trade license is not enough for residential work — you also need the $220/2-year HIC registration. Operating without HIC on residential property can void your contract enforceability and lien rights under CGS § 20-429.
Trade Name 5-Year Renewal Is New
As of January 1, 2025, town-clerk Trade Name (DBA) certificates expire 5 years after filing — a change from the prior indefinite term. If you registered a DBA in 2020 expecting it to last forever, plan to refile by 2030. New DBAs from 2025 forward have built-in 5-year sunset.

What is Connecticut’s income tax rate in 2026?
Connecticut has a graduated income tax with seven brackets ranging from 2% to 6.99%. Single filer brackets (2026): 2% on $0-$10,000; 4.5% on $10,001-$50,000; 5.5% on $50,001-$100,000; 6% on $100,001-$200,000; 6.5% on $200,001-$250,000; 6.9% on $250,001-$500,000; 6.99% over $500,000. MFJ thresholds roughly double. Connecticut also imposes a 2% Phase-Out Add-Back at moderate incomes (beginning $56,500 single / $100,500 MFJ) and a tax-benefit recapture for high earners.

Do I need a business license in Connecticut?
Connecticut has no statewide general business license — there is no single “CT business license” you apply for. Many municipalities (towns/cities) require local business permits or licenses. Because Connecticut has no county government, all local permitting goes through 169 distinct town/city halls. Industry-specific state licensing runs through DCP (HVAC, plumbing, electrical, cosmetology, real estate, HIC), OEC (daycare), DPH (food, certain health professions), DEEP (pesticide applicators), and DESPP (private investigators).
Does Connecticut have a DBA / trade name requirement?
Yes. If your business operates under a name other than its registered legal name, you must file a trade name certificate with the town clerk where your business is primarily located. The fee is typically $10-$20 (varies by town). Important change: trade name certificates filed on or after January 1, 2025 expire after 5 years and must be renewed. Older DBAs that have been in place indefinitely may need re-examination.
What is the Home Improvement Contractor (HIC) registration?
HIC registration is required for any business performing work on residential property in Connecticut — including HVAC, plumbing, electrical, landscaping with hardscape, painting, roofing, cleaning services with repairs, and similar trades. Registration through DCP under CGS § 20-419+. Fee: $220 for 2 years. Per-business registration (not per-employee). Operating without HIC on residential property work can void your contract enforceability and lien rights under CGS § 20-429. The HIC requirement applies to residential property only — commercial-only contractors do not need HIC.
