Last updated: May 3, 2026. CT cleaning service taxability under CGS § 12-407(2)(i)(AA) and (W), DRS Janitorial Services Ruling 9037, sales tax permit fee, casual sale exception, NCCI class code references, and HIC registration scope verified against portal.ct.gov/drs, Connecticut General Assembly statute, and DCP registration guidance as of this date.

How to Start a Cleaning Service in Connecticut (2026)

Starting a cleaning service in Connecticut is structurally different from most states because Connecticut taxes janitorial services in full at the 6.35% sales tax rate. Where most states either don’t tax cleaning services at all (Florida, Texas) or tax only commercial cleaning (some Northeast states), Connecticut taxes residential AND commercial janitorial under CGS § 12-407(2)(i)(AA), as amended by Public Act 89-251 of 1989. Window cleaning is separately taxable under § 12-407(2)(i)(W). Maintenance services to real property — housewashing, chimney sweeping, carpet cleaning, snow removal — are also taxable. The first compliance step for any new CT cleaning business is registering for a Sales Tax Permit through DRS.

Three structural realities define the CT cleaning service market in 2026. First, the $16.94/hour state minimum wage (second-highest in the US, indexed annually under PA 19-4) is structurally above traditional cleaning wages — operators face wage compression and high turnover unless they pay above floor. Second, Connecticut’s workers’ compensation triggers at the very first employee under CGS § 31-275 with no minimum threshold — solo operators are exempt, but the moment you hire, you need WC coverage. And third, the new Paid Sick Leave law under PA 24-8 covers cleaning services with 11+ employees as of January 1, 2026 (and expands to ALL employers on January 1, 2027) — a payroll obligation many small CT cleaning operators only became aware of when they crossed the headcount threshold.

How to Start a Cleaning Service in Connecticut (Step by Step)

Step 1: Confirm CT Taxes Your Specific Cleaning Service

Connecticut is one of a minority of US states that taxes routine cleaning services. Get this right before you start invoicing — the DRS Audit Division actively audits cleaning operators for under-collection. The relevant statutory categories under CGS § 12-407(2)(i):

Janitorial Services (Subdivision AA) — Taxable for Both Homes and Commercial

Public Act 89-251 of 1989 expanded “janitorial services” under § 12-407(2)(i)(AA) to cover all instances. The statutory definition is broad:

• Floor, wall, ceiling, and woodwork cleaning
• Carpet and upholstery cleaning
• Disinfecting and cleaning of restrooms
• Waxing and polishing of furniture
• Dusting and vacuuming
• Emptying wastebaskets

The statute applies to cleaning of homes, offices, and commercial property equally. There is no residential carve-out — the residential vs. commercial distinction that exists in some other states does not apply in Connecticut.

Window Cleaning (Subdivision W) — Separately Taxable

Window cleaning services — including cleaning of windows and exterior and interior glass — are separately taxable under § 12-407(2)(i)(W). This applies to building exterior window-washing and interior glass cleaning.

Maintenance Services — Taxable for Real Property

Maintenance services include the upkeep, care, or cleaning of buildings and real property on a regular basis. Taxable maintenance includes:

• House washing (pressure washing siding, decks, walkways)
• Chimney sweeping
• Carpet cleaning
• Snow removal (residential and commercial both)
• Gutter cleaning

If your business adds any of these services to a cleaning bundle, those revenues are also taxable at 6.35%.

The Casual Sale Exception

The statute includes a narrow casual-sale exception. Janitorial services provided to 3 or fewer residences per year by an individual who is not otherwise engaged in the trade or business of providing such services are not taxable. This covers neighbors helping neighbors, occasional one-off summer-cleaning gigs, and similar low-frequency arrangements. Once you operate as a cleaning business — even part-time — the exception does not apply.

The statute also exempts:

• Direct W-2 employment of a janitor/housekeeper/maid by the resident (the resident pays wages, not a service fee)
• Direct W-2 employment of a janitor/custodian by a business as in-house staff

The exception is for genuine W-2 employment, not 1099 contractor arrangements. Misclassifying contracted cleaners as direct employees to avoid sales tax is a CT DRS audit trigger.

Location-of-Service Rule

The taxability is location-based. If janitorial services are rendered at real property located within Connecticut, the services are taxable — regardless of where materials were purchased, where the contract was negotiated, where the bill is mailed, or whether the customer is a CT resident. A New York-based corporate cleaning contractor servicing a Stamford office pays CT sales tax on those services.

Step 2: Register for a Sales Tax Permit Through DRS

Register through myconneCT via the REG-1 application. The Sales Tax Permit fee is $100 for a 2-year permit (auto-renewed while your account is active). You will collect 6.35% sales tax on every taxable cleaning, window cleaning, and maintenance service rendered to property in Connecticut.

Filing frequency:

• Monthly if average monthly tax liability is $4,000+
• Quarterly for moderate-revenue operators
• Annual if your average annual tax liability is under $1,000

Returns and payments are filed through myconneCT. Late filing penalties + interest accrue daily — set automatic reminders before each due date.

Sales Tax on Invoices

Best practice: itemize the 6.35% sales tax separately on every invoice (commercial and residential), with a clear line item showing the pre-tax service amount + the tax. This prevents customer confusion and creates a clean audit trail. For tax-exempt customers (federal/state government, qualified 501(c)(3) nonprofits, etc.), collect a current exemption certificate (CERT-119 for nonprofit, CERT-122 for government) before the first invoice.

Step 3: Form Your CT LLC at business.ct.gov

File the Certificate of Organization at business.ct.gov for $120. Annual report $80, due January 1 – March 31 every year. Operating Agreement is recommended (not state-filed). Trade name (DBA) registration with the town clerk if operating under a name other than your registered legal name — note 5-year expiration for filings on or after January 1, 2025.

Many CT cleaning operators start as sole proprietors and convert to LLC after the first year of revenue justifies the formation cost. Conversion is straightforward — file a new Certificate of Organization in the LLC name and update Sales Tax Permit, EIN, and bank accounts.

Step 4: Decide Whether You Need HIC Registration

This is a real CT-specific trap. The Home Improvement Contractor (HIC) registration under CGS § 20-419+ applies to home improvement work — repairs, alterations, conversions, modernizations, additions on residential property. Routine cleaning, vacuuming, dusting, and window washing are not home improvement.

But several cleaning-adjacent services do cross the line:

• Move-out cleans with patch-and-paint: drywall patching + paint touch-up = home improvement
• Light fixture replacement during deep clean: electrical fixture work = home improvement (and may need a separate electrical license)
• Plumbing fixture cleaning involving disassembly + reassembly: may cross into plumbing scope
• Post-construction cleaning + minor finish work: finish carpentry or trim = home improvement
• Carpet replacement or installation: definitively home improvement (and CT carpet installers carry HIC + sales tax)

Pure cleaning service does not need HIC. Cleaning + repair hybrids do — register with DCP for $220 every 2 years. Operating without HIC on residential repair work can void contract enforceability and lien rights under CGS § 20-429.

Step 5: Get General Liability + Bond + Workers’ Compensation

General Liability Insurance

General liability for cleaning services typically runs $400-$1,500/year for $1M per occurrence / $2M aggregate coverage. Premium is influenced by revenue, employee count, and claims history. Most commercial property managers, corporate facilities teams, and government contracts require proof of GL — typically with the client named as an Additional Insured on a Certificate of Insurance.

Janitorial / Fidelity Bond

Connecticut does not require a state-level janitorial bond, but most commercial clients require a janitorial dishonesty bond as a condition of contract. Typical coverage: $10,000-$100,000 with annual premiums of $100-$500. The bond protects the client from employee theft of cash, jewelry, electronics, or trade secrets while cleaning. Pair the bond with a clear background-check policy for staff and a written cash-handling protocol.

Workers’ Compensation — Mandatory at 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. Coverage is provided through the private insurance market — Connecticut has no monopolistic state fund. Several NCCI class codes apply depending on cleaning type:

• NCCI 9014 — Janitorial Services NOC: commercial office, school, retail janitorial
• NCCI 9015 — Building Service Workers, Hotels and Restaurants: hospitality cleaning
• NCCI 0917 — Domestic Workers – Residential: residential maid services

Premium rates are moderate (lower than construction trades but higher than office classes). Sole proprietors and LLC members without employees aren’t required to carry coverage but may elect to do so.

Step 6: Stack the CT Payroll Obligations

$16.94/hr Minimum Wage in 2026

CT’s $16.94/hour minimum wage in 2026 is the second-highest in the US, behind Washington’s $17.13. Public Act 19-4 indexes the rate annually to the federal Employment Cost Index — the 2026 increase was 3.6% from 2025’s $16.35. Plan compensation budgets accordingly. Cleaning services cannot pay under the floor; many CT operators pay $18-$22/hour for experienced cleaners to reduce turnover.

CT PFML 0.5% Employee-Only

The Connecticut Paid Family and Medical Leave program: 0.5% of employee wages, employee-only (no employer match), capped at the federal Social Security wage base ($184,500 in 2026, max $922.50/year per employee). Maximum weekly benefit $1,016.40. The employer remits, but the employee bears the cost.

UI Tax 2026

2026 UI wage base is $27,000 (up from $26,100 in 2025). New-employer rate dropped to 1.9% (down from 2.2%). Experience-rated rates after Year 4 range 1.1%-9.9%. CT applied a 1.125 rate-reduction divisor in 2026 to soften the wage-base increase.

Connecticut Paid Sick Leave Under PA 24-8

Public Act 24-8 of 2024 dramatically expanded CT’s Paid Sick Leave law. Phase-in:

• January 1, 2025: employers with 25+ employees
• January 1, 2026: employers with 11+ employees ← currently in effect
• January 1, 2027: ALL employers (1+ employees)

Cleaning services with 11-25 employees crossed the new threshold January 1, 2026. The “service worker” concept that limited the prior 2011 law was eliminated as of January 1, 2025 — covered employers must provide paid sick leave to all employees, with limited exceptions for “seasonal employees” (≤120 days/year). Accrual: 1 hour per 30 hours worked, up to 40 hours per year.

Step 7: Bid Commercial Work Understanding the Taxability

For commercial cleaning bids in Connecticut:

• Quote the pre-tax service price + 6.35% sales tax separately, OR quote tax-included with the rate disclosed in writing
• Property managers and facility directors expect itemized tax on monthly invoices
• For multi-location accounts, calculate sales tax per CT location served (the property location rule)
• Federal/state government and qualified 501(c)(3) nonprofits may be tax-exempt — collect the appropriate CT exemption certificate (CERT-119 for nonprofit, CERT-122 for government) before the first invoice
• Track sales tax collected separately from operating revenue — it is a fiduciary obligation to remit, not your money

For residential cleaning, post tax-inclusive pricing clearly so homeowners aren’t surprised at billing. Quotes that say “$120 per cleaning + tax” should clearly disclose the 6.35% rate (so total = $127.62).

Connecticut Cleaning Service Market: Where the Demand Is

Fairfield County: NY-Metro High-End Residential

Stamford, Greenwich, Norwalk, Westport, Darien, and Wilton host households with NYC-metro income levels and demanding service expectations. Premium pricing on residential deep cleans (often $300-$600 for a 4-5 bedroom home), recurring weekly service contracts ($150-$250/visit), and luxury-finish-aware staff. Operators in this corridor often hire cleaners willing to handle delicate finishes (marble, brass, antique furniture). Estate-management firms and concierge services frequently refer cleaning subcontractors.

Hartford Insurance Corridor: Office and Commercial Janitorial

Hartford is the state capital and home to The Hartford, Travelers, Aetna/CVS Health, plus state government offices. Office janitorial contracts typically run nightly or 5x/week with multi-year terms. NCCI 9014 workers’ comp class. Bidding requires Certificate of Insurance with high limits ($2M GL minimum, often $5M umbrella), janitorial bond, and W-2 employee verification (subcontractor crews are often disqualified by larger property managers).

New Haven and Yale University Healthcare

Yale University, Yale New Haven Health System, and surrounding biotech facilities drive specialized cleaning demand — laboratory environments, biosafety cabinet protocols, healthcare facility cleaning under joint commission standards. Higher per-hour rates and recurring contracts. Often requires HazWoper or healthcare-specific training.

Casino-Industry Hospitality Cleaning

Foxwoods Resort Casino and Mohegan Sun (on tribal land in Eastern Connecticut) anchor large hospitality cleaning supply chains. NCCI 9015 hotel/restaurant class applies. Contract subcleaning, room turnaround at scale, and large-employer payroll mechanics — operators in this corner of CT often run multi-shift, multi-property crews.

Shoreline Seasonal: Old Saybrook to Mystic

The CT shoreline (Old Saybrook, Niantic, Westbrook, Stonington, Mystic) has heavy seasonal demand for short-term rental turnover cleans (Memorial Day through Columbus Day). Many operators run hybrid models — year-round small commercial accounts plus summer seasonal residential turnover crews.

What Catches Connecticut Cleaning Operators Off Guard

• CT taxes residential AND commercial janitorial. Operators expanding from Florida, Texas, or Georgia (where most cleaning is sales-tax-free) are surprised that CT taxes both — and at the same 6.35% rate as a retail sale.
• The casual sale exception is narrower than it sounds. 3-or-fewer-residences-per-year applies only to individuals not in the trade. Side-gig cleaners building up to a business cross into taxable territory faster than they realize.
• Location of service controls — not where you’re based. A NY-based or MA-based cleaning operator servicing a CT property pays CT sales tax. There is no “out-of-state operator” exemption.
• Snow removal is taxable too. Many cleaning companies add winter snow removal as a maintenance service — that revenue is also taxable at 6.35% under CGS § 12-407(2)(i).
• HIC trap on cleaning + repairs. Adding even minor home repair (drywall patching, light fixture replacement) to a cleaning service triggers HIC registration ($220/2 years) under CGS § 20-419+. Operating without HIC on residential repair work can void contract enforceability.
• $16.94/hr minimum wage compresses cleaning wages. CT’s indexed minimum wage hits cleaning harder than most service industries. Operators who pay floor face very high turnover — many operators pay $18-$22/hr for experienced staff.
• Paid Sick Leave kicked in at 11 employees on January 1, 2026. Operators who hired their 11th employee that month may not realize they crossed the new PA 24-8 threshold. Verify your headcount and set up accrual.
• Workers’ comp at first employee. No threshold under CGS § 31-275 — the first hire triggers WC. Operators expanding from threshold states (FL 4-employee, TX optional) must adjust hiring economics.
• NCCI class code matters. Misclassifying residential domestic cleaning under 9014 (commercial) or vice versa creates premium audit risk. 9014 vs 9015 vs 0917 are not interchangeable.
• Sales tax is a fiduciary obligation. Money collected as sales tax is held in trust for the state. Spending it on operating expenses creates real personal liability if the business ever can’t remit.

Frequently Asked Questions

Are cleaning services taxable in Connecticut?

Yes — Connecticut is one of a minority of states that taxes routine cleaning services. Janitorial services are FULLY taxable at the flat 6.35% sales tax rate under CGS § 12-407(2)(i)(AA), applying to both homes and commercial properties. The statute defines janitorial broadly: floor/wall/ceiling/woodwork cleaning; carpet/upholstery cleaning; disinfecting and cleaning of restrooms; waxing and polishing of furniture; dusting and vacuuming; emptying wastebaskets. Window cleaning is separately taxable under § 12-407(2)(i)(W). Maintenance services (housewashing, chimney sweeping, carpet cleaning, snow removal) are also taxable. The taxability is location-of-service-based: if rendered at real property in CT, the service is taxable regardless of where the contract was negotiated or where the bill is mailed.

What is the casual sale exception for CT janitorial services?

Connecticut’s casual sale exception covers janitorial services provided to 3 or fewer residences per year by an individual who is NOT otherwise engaged in the trade or business of providing such services. If you clean 3 or fewer homes a year as a side gig and have no other cleaning income, the service is not taxable. The exception does not apply once you become a full-time or part-time cleaning business operator. The statute also exempts the direct W-2 employment of a janitor/housekeeper/maid by the resident and a janitor/custodian directly employed by a business as W-2 staff — these are wages, not taxable services.

Do I need a Home Improvement Contractor (HIC) registration to clean in Connecticut?

Pure cleaning service does not require HIC registration. The HIC registration under CGS § 20-419+ applies to home improvement work — repairs, alterations, conversions, modernizations, additions to residential property. Routine cleaning, vacuuming, dusting, and window washing are not home improvement. But if your service includes a repair or construction component on residential property — drywall patching after deep cleans, light fixture replacement, plumbing reinstallation, etc. — you cross into HIC territory and must register with DCP for $220 every 2 years. Most pure cleaning operators don’t need HIC; service-and-repair hybrids do.

What workers’ comp NCCI class code applies to a CT cleaning business?

Several NCCI codes apply depending on the type of cleaning. NCCI 9014 (Janitorial Services NOC) covers most commercial janitorial work — office buildings, schools, retail. NCCI 9015 (Building Service Workers and Drivers) covers hotels and restaurants. NCCI 0917 (Domestic Workers – Residential) covers residential cleaning specifically. Premium rates vary by code and Connecticut classification factors. Workers’ compensation is mandatory at the first employee under CGS § 31-275 — no threshold. Sole proprietors and LLC members without employees aren’t required to carry coverage but may elect to do so.

Does Connecticut require a janitorial bond?

Connecticut does not require a state-level janitorial bond, but most commercial clients (property management firms, corporate offices, government contracts) require a janitorial dishonesty bond as a condition of contract. Typical coverage runs $10,000-$100,000 with annual premiums of $100-$500. The bond protects the client from employee theft of cash, jewelry, electronics, or trade secrets while cleaning. Pair the bond with a clear background-check policy for staff and a written cash-handling protocol.

Is snow removal taxable in Connecticut?

Yes — snow plowing and removal services are taxable in Connecticut at 6.35% as a maintenance service to real property under CGS § 12-407(2)(i). The taxability applies regardless of whether the property is residential or commercial. Snow plowing contractors must register with DRS for a Sales and Use Tax Permit. The casual and occasional sales exception applies only narrowly — established snow removal businesses, including cleaning companies that add snow removal as a winter service, must collect tax. Bundle this into your cleaning company’s tax-collection process if you offer winter maintenance.

How much does it cost to start a cleaning business in Connecticut?

Total startup typically runs $2,000-$30,000. Solo home-cleaning operators starting cash-only with their own car and supplies can start under $3,000. Add LLC formation $120 + $80 annual report, $100 Sales Tax Permit (2 years), $400-$1,500/year general liability insurance, $100-$500/year janitorial bond if commercial, NCCI 9014/0917 workers’ comp reserve once you hire, $1,500-$5,000 in initial supplies and equipment (vacuum, mops, supplies, branding, marketing). Small commercial-team cleaning companies typically launch at $15,000-$30,000 with vehicle, branded supplies, multi-employee scheduling software, and commercial insurance.
