How to Start a Cleaning Service in Connecticut (2026)

Last updated: September 15, 2026

Connecticut generally taxes residential and commercial janitorial services at 6.35%. Register with DRS before making taxable sales, check exemptions and separate sales tax from operating revenue. The current janitorial category is CGS §12-407(a)(37)(Y); window cleaning is addressed separately in (W). DRS service-tax sources.

For hiring, plan for Connecticut’s $16.94 minimum wage in 2026, required workers’ compensation, payroll and leave obligations. Paid sick leave generally covers employers with 11 or more employees in 2026 and expands to one or more in 2027, subject to statutory exceptions.

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

Step 1: Confirm CT Taxes Your Specific Cleaning Service

Confirm each service and any exemption before invoicing. Current section 12-407(a)(37) lists taxable service categories; janitorial, window-cleaning and maintenance provisions are distinct.

Janitorial Services — Subdivision (Y)

Janitorial services cover routine interior cleaning tasks, including:

• 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

Ordinary janitorial services can be taxable at both residential and commercial properties. Specific exemptions still need their own analysis.

Window Cleaning (Subdivision W) — Separately Taxable

Window cleaning is separately addressed by current CGS §12-407(a)(37)(W). Check exemption conditions instead of assuming every customer or property is taxable.

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

These maintenance services generally are taxable at 6.35%. Check specific exemptions and the actual service before treating an entire bundle as taxable or exempt. DRS building-contractor and maintenance guidance.

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

A directly employed cleaner’s wages are different from purchasing an independent cleaning business’s services. The employment relationship must be real, not a label used to avoid tax.

Location-of-Service Rule

For taxable cleaning at Connecticut property, an out-of-state business generally must collect and remit Connecticut tax. Where the customer receives the service matters; an out-of-state address does not itself create an exemption.

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.

Follow the filing frequency DRS assigns to your account:

• Monthly, quarterly or annual reporting depends on the applicable rules and DRS assignment; do not use average monthly tax of $4,000 as the test.
• The statutory reduced-frequency thresholds refer to tax liability over the preceding twelve months, not average monthly revenue.
• Confirm your assigned frequency and next due date in myconneCT before the first return.

File and pay by the due date shown for the account. Late filing or payment can create penalties and interest. DRS sales-tax guidance.

Sales Tax on Invoices

Show the taxable service amount and 6.35% tax clearly on the invoice and keep tax receipts separate. For an eligible exempt purchase, obtain the appropriate completed certificate and follow its conditions: CERT-134 for qualifying government purchases or CERT-119 for qualifying exempt-organization purchases. A customer’s name or nonprofit label alone does not establish exemption.

Step 3: Choose Your Structure and Register It

A sole proprietorship is an option. If choosing an LLC, file the $120 Certificate of Organization and budget for the $80 annual report due January 1–March 31. Check the town clerk’s trade-name requirements and deadlines if using a different business name.

Changing from a sole proprietorship to an LLC may require new or updated tax registrations, contracts, insurance and banking arrangements. Confirm requirements before billing under the new entity.

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)

Ordinary cleaning alone does not require Home Improvement Contractor registration. If adding covered residential repairs, check DCP registration and any separately licensed trade work first. HIC registration costs $220 annually and expires March 31; DCP also requires at least $20,000 general liability coverage. DCP HIC requirements.

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

General Liability Insurance

General liability can cover specified third-party bodily injury and property-damage claims, subject to policy terms and exclusions. Damage to property in your care, custody or control may need particular coverage. Obtain the client’s required limits and endorsements before signing; a certificate of insurance does not itself add coverage or additional-insured status.

Janitorial / Fidelity Bond

A janitorial service bond can protect customers against covered employee theft, subject to the bond’s exclusions, covered people and claim conditions. Some clients request one; it is not a universal requirement for ordinary cleaning. Ask for a quote at the limit your contract requires. It does not replace liability or workers’ compensation insurance.

Workers’ Compensation — Mandatory at First Employee

Arrange workers’ compensation before covered employees start. Check owner/member status and statutory exceptions with the Connecticut Workers’ Compensation Commission. Have the insurer classify your actual cleaning operations and confirm any permitted payroll separation. A customer’s building type alone does not determine the correct class code. Disclose residential, commercial, height work and specialized services; do not choose a code simply because its quoted rate is lower.

• Disclose all ordinary and specialized cleaning operations.
• Ask the insurer to confirm the applicable state classification rules.
• Keep any required payroll separation records.

Premiums depend on the assigned classification, payroll and policy factors. Confirm owner/member inclusion or exclusion rather than assuming it.

Step 6: Stack the CT Payroll Obligations

$16.94/hr Minimum Wage in 2026

Connecticut’s 2026 minimum wage is $16.94 per hour. Budget for all compensable hours and applicable overtime, not just time inside the customer’s premises. DOL hours-worked guidance.

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)

In 2026, the expanded sick-leave law generally covers employers with 11 or more employees; employers already covered in 2025 remain covered. Accrual is one hour per 30 worked, up to 40 annually. Check DOL’s headcount, use, carryover and employee-exemption rules. CT DOL paid sick leave.

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)
• For an eligible exempt purchase, obtain the appropriate completed certificate and follow its conditions: CERT-134 for qualifying government purchases or CERT-119 for qualifying exempt-organization purchases. A customer’s name or nonprofit label alone does not establish exemption.
• 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

For Fairfield County residential jobs, inspect the surfaces and condition, agree on included tasks and estimate labor and travel. Delicate finishes may require different products and documented instructions; obtain actual local quotes rather than treating a generic range as market data.

Hartford Insurance Corridor: Office and Commercial Janitorial

For office contracts, request the written service schedule, staffing, insurance and screening requirements. Do not assume every building requires the same limits or accepts the same subcontracting arrangements.

New Haven and Yale University Healthcare

For university, laboratory or healthcare jobs, request the facility’s protocols and assess actual employee exposure. HAZWOPER is not a generic requirement for all healthcare cleaning; specialized hazards require separate analysis and training.

Casino-Industry Hospitality Cleaning

For hospitality work on tribal property, check the tribe’s business and procurement rules, required access and actual job scope. Have the insurer classify the operation; do not assign a hotel code solely from the client’s name.

Shoreline Seasonal: Old Saybrook to Mystic

For shoreline accounts, confirm the customer’s occupied dates, turnover deadlines and off-season needs. Build staffing around actual contracts.

What Catches Connecticut Cleaning Operators Off Guard

• Connecticut generally taxes both residential and commercial janitorial work at 6.35%. Do not import another state’s treatment; Texas also generally taxes cleaning services.
• 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 generally is taxable maintenance; check the DRS service rules and any exemption that applies to the customer or property.
• Ordinary cleaning alone does not require Home Improvement Contractor registration. If adding covered residential repairs, check DCP registration and any separately licensed trade work first. HIC registration costs $220 annually and expires March 31; DCP also requires at least $20,000 general liability coverage. DCP HIC requirements.
• The $16.94 minimum wage is a floor, not a complete labor budget. Include overtime, compensable travel, payroll tax and leave.
• Paid sick leave generally covers employers with 11 or more employees in 2026. Confirm DOL’s headcount method and eligibility rules and set up records before assuming coverage starts only when a particular worker is hired.
• 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.
• Have the insurer classify your actual cleaning operations and confirm any permitted payroll separation. A customer’s building type alone does not determine the correct class code. Disclose residential, commercial, height work and specialized services; do not choose a code simply because its quoted rate is lower.
• 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.
