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

Step 1: Form Your Business Entity

Most cleaning business owners choose an LLC for liability protection. File your Certificate of Organization at business.ct.gov ($120). Approved in 1-3 business days. Your LLC name must include “LLC” or “Limited Liability Company.”

If you want to operate under a brand name (e.g., “Sparkling Clean CT” rather than “Smith Cleaning LLC”), file a trade name certificate with your town clerk ($10-$20). As of January 1, 2025, trade name certificates expire after 5 years.

Step 2: Get Your Federal EIN

Apply for a free EIN at IRS.gov. You’ll receive it immediately. Required to open a business bank account, hire employees, and file taxes.

Step 3: Register for Sales Tax – Cleaning Services ARE Taxable in CT

Connecticut cleaning businesses must collect sales tax. Unlike many states, janitorial and cleaning services are explicitly taxable in Connecticut under CGS § 12-407(2)(i)(Y):

• All routine commercial and residential cleaning services: Taxable at 6.35%. This includes interior cleaning, floor care, carpet cleaning, window washing, restroom sanitation, dusting, vacuuming, and similar services.
• Exception – casual sale cleaning: A single isolated cleaning transaction (not conducted as a regular business) may be exempt as a “casual sale.” This exception does not apply to ongoing cleaning businesses.
• Cleaning products/supplies sold to clients: Also taxable at 6.35%.

Register for a sales tax permit at myconneCT (REG-1 application). The permit costs $100 and must be displayed at your place of business. It is valid for 2 years and auto-renewed by the state while your account is active. See the DRS Services Subject to Sales Tax page for the full list of taxable services.

Step 4: Get Bonded and Insured

While Connecticut does not require a specific cleaning license, clients – especially commercial accounts – expect you to be bonded and insured:

• Janitorial Bond (Surety Bond): Protects clients if an employee steals from their property. Typical cost: $100-$300/year for a $10,000-$25,000 bond. Required by most commercial clients and property management companies.
• General Liability Insurance: Covers property damage or injuries caused by your work. Standard: $1 million per occurrence / $2 million aggregate. Annual cost: $500-$2,000 depending on revenue and coverage limits.
• Workers’ Compensation Insurance: Mandatory in Connecticut the moment you hire your first employee. No minimum threshold. Purchase from a private carrier.
• Commercial Auto Insurance: If using vehicles for work, personal auto insurance does not cover business use. Commercial policy needed.

Step 5: Home Improvement Contractor (HIC) Registration

If any of your services include home improvements on residential property – painting, carpet installation, minor repairs in addition to cleaning – you must register as a Home Improvement Contractor with the Connecticut Department of Consumer Protection. Fee: $220 for a 2-year registration. Pure cleaning services without any repair/improvement component do not require HIC registration.

Step 6: Register for Employer Taxes (When Hiring)

Once you hire employees, register for:

• Connecticut Withholding Tax via myconneCT
• Unemployment Insurance through CT DOL (new employer rate: 1.9% on first $27,000 of wages)
• Paid Leave CT: 0.5% of wages (employee-paid, employer remits quarterly)
• Report new hires to CT New Hire Reporting Center within 20 days

Frequently Asked Questions

Do I need a license to start a cleaning business in Connecticut?

No, Connecticut does not require a specific state license to operate a cleaning service. However, you must form a legal business entity (LLC recommended), register for applicable taxes, obtain proper insurance and bonding, and check for any local municipality requirements. If your services include home improvements or repairs on residential property, you need a Home Improvement Contractor (HIC) registration from CT DCP.

Is cleaning taxable in Connecticut?

Yes. Janitorial and cleaning services are explicitly taxable in Connecticut under CGS § 12-407(2)(i)(Y). All standard cleaning services – residential, commercial, carpet cleaning, floor care – are subject to the 6.35% sales tax. The only exception is a single isolated “casual sale” not conducted as regular business. You must register for a $100 sales tax permit at myconneCT and collect 6.35% on all cleaning service invoices. Connecticut has no local sales taxes – 6.35% is the uniform statewide rate.

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

Minimal startup costs include $120 for LLC formation plus $80 for the first annual report, roughly $500-$2,000 for liability insurance, and $100-$300 for a janitorial bond. Total startup costs typically range from $1,100 to $6,500 depending on whether you need equipment, a vehicle, and marketing materials.

Do I need workers’ comp for a cleaning business in Connecticut?

Yes, as soon as you hire your first employee. Connecticut requires workers’ compensation insurance for any employer with even one employee. There is no minimum threshold. Coverage must be from a qualified private carrier. Sole proprietors with no employees are not required to carry workers’ comp but may elect coverage voluntarily.

Do I need to be bonded to start a cleaning company in Connecticut?

Connecticut does not legally require a janitorial bond, but it is practically essential for getting clients – especially commercial accounts. A janitorial surety bond ($10,000-$25,000 face value) costs approximately $100-$300 per year and protects clients if an employee steals from their property. Most commercial cleaning contracts and property managers require proof of bonding.

Can I operate a cleaning business from home in Connecticut?

Yes, most cleaning businesses operate from home since you travel to client locations. Check your municipality’s home occupation rules – some towns require a home occupation permit for operating a business from a residential address. The permit is typically inexpensive but must be obtained before advertising your home address as a business location.
