Janitorial business licensing — Connecticut

Last reviewed: June 2, 2026  |  Primary sources: Connecticut Secretary of State; CT DRS; CT WCC; SBA.gov

Connecticut's signature compliance obligation for commercial cleaning contractors is its sales tax on janitorial services — a rule that catches many BSCs expanding from neighboring New York and Massachusetts, where cleaning labor is not taxed. Beyond sales tax, the state's paid sick leave phaseout (now covering all employers by 2027), the Connecticut Fair Employment Practices Act (CFEPA) covering employers with one or more employees, and a tight workers' compensation framework create a compliance environment that demands careful attention from day one.

Sales Tax on Janitorial Services — Conn. Gen. Stat. § 12-407

Connecticut imposes a 6.35% sales and use tax on janitorial services, explicitly enumerated under Conn. Gen. Stat. § 12-407(a)(2). The taxable list also includes window cleaning, swimming pool cleaning, dry cleaning, exterminating, and services to commercial or income-producing real property. The tax applies to the entire gross charge — labor and materials combined — with no carve-out for residential cleaning at owner-occupied single-family homes. A BSC invoicing a Hartford office building $5,000/month owes $317.50 in Connecticut sales tax on that invoice. Register for a Sales and Use Tax Permit through the Connecticut Department of Revenue Services (DRS), 450 Columbus Blvd., Hartford, CT 06103, (860) 297-5962. Companies with annual CT tax liability exceeding $4,000 must file monthly instead of quarterly.

Business Registration and Municipal Licensing

Entity registration is through the Connecticut Secretary of the State (SOTS), 165 Capitol Avenue, Hartford, CT 06106, (860) 509-6000. LLC Articles of Organization cost $120; corporations pay $250. Sole proprietors using a trade name file a Trade Name Certificate with the town clerk ($10–$25 depending on municipality). Connecticut has no separate statewide janitorial business license, but Hartford, New Haven, Bridgeport, and Stamford each have local business registration requirements that cleaning contractors must fulfill before commencing operations within those city limits.

Workers' Compensation — Every Employee from Day One

Connecticut requires workers' compensation for every employer with one or more employees from the first day of employment under Conn. Gen. Stat. § 31-275 et seq. There is no minimum headcount or payroll threshold. Coverage is placed with a private admitted carrier. Janitorial workers carry NCCI code 9014, rated approximately $10–$14 per $100 of payroll. The Workers' Compensation Commission (wcc.state.ct.us) administers claims through eight district offices. Sole proprietors and partners are automatically excluded from coverage but may elect inclusion in writing. Misclassifying employees to avoid WC premiums can trigger a stop-work order and retroactive premium assessment.

Connecticut Fair Employment Practices Act (CFEPA)

The Connecticut Fair Employment Practices Act (CFEPA), Conn. Gen. Stat. § 46a-60, applies to all private employers with one or more employees — one of the broadest coverage thresholds in the country. CFEPA prohibits discrimination on the basis of race, color, religion, national origin, sex, gender identity or expression, age (40+), pregnancy, disability, genetic information, and — since October 1, 2022 — status as a victim of domestic violence. The Connecticut Commission on Human Rights and Opportunities (CHRO) enforces CFEPA and may award back pay, reinstatement, and cease-and-desist orders. CHRO complaints must be filed within 300 days. National origin discrimination claims are a meaningful risk for cleaning companies with predominantly immigrant workforces.

Connecticut Paid Sick Leave — Phased Expansion Through 2027

Connecticut's expanded paid sick leave mandate (Public Act 24-8) phases in over three years: employers with 25+ employees were covered starting January 1, 2025; those with 11+ employees are covered from January 1, 2026; all employers with one or more employees are covered from January 1, 2027. Per the 2025 CGA Research Report, employees accrue 1 hour per 30 hours worked (up from 1 per 40 previously), capped at 40 hours annually. Leave is usable after 120 calendar days. Civil penalties reach $100 per violation and $500 per retaliation incident. By 2027, every Connecticut cleaning company — even a one-person operation — must provide paid sick leave.

Unemployment Insurance — Connecticut Department of Labor

Connecticut UI is administered by the Connecticut Department of Labor, UI Tax Division, 200 Folly Brook Blvd., Wethersfield, CT 06109, (860) 263-6000. New employers pay 3.0% on the first $25,000 of each employee's wages — one of the nation's highest wage bases. Experienced employer rates range from 1.9% to 6.8%. Employers become liable once they pay $1,500 in wages in any calendar quarter or employ at least one worker for 20 weeks. Quarterly reports and payments are due April 30, July 31, October 31, and January 31.

Independent Contractor Classification — Connecticut's ABC-Like Test

For UI and workers' compensation purposes, Connecticut applies a three-part test closely resembling an ABC standard: the worker must be (1) free from direction and control; (2) performing service outside the usual course of business or outside the employer's place of business; and (3) customarily engaged in an independently established trade or occupation. Prong (2) is the same disposition as an ABC test — nearly every cleaning crew member performing a BSC's core service fails it. The Connecticut Department of Labor's Wage and Workplace Standards Division has specifically targeted commercial cleaning firms in New Haven and Hartford counties in multi-year misclassification audit sweeps. Reclassification findings trigger back UI taxes, penalties, and interest for multiple years.

Chemical Safety and Government Contract Notes

Connecticut DEEP is developing PFAS product regulations; BSCs using fluorosurfactant-containing floor finishes should monitor Connecticut DEEP for updates. State facility cleaning contracts procured through the State Contracting Portal require certification under the Connecticut Set-Aside Program if seeking MBE/SBE preferences. Hartford city facility contracts may require living-wage compliance under Hartford Code § 2-822. BSCs should maintain SDS binders and annual HazCom training records for all crew members who handle chemicals.
