In Connecticut, cleaning is a taxable service whether the job is a house or an office building, so sales tax belongs on the residential and commercial sides of your books alike. The state uses the ABC test to decide whether your cleaners count as employees for unemployment insurance, and the minimum wage is $16.94 an hour for 2026, rising to $17.48 on January 1, 2027.
A lot of cleaning owners assume house cleaning sits outside sales tax. Connecticut doesn't work that way: its regulation on janitorial services covers dwellings as well as commercial buildings, and that one rule shapes how I set up the books for a Connecticut cleaning company. Below I walk through sales tax, the employee or subcontractor question, payroll registration with the two state agencies, the minimum wage, and what all of it means for the numbers you look at each month.
Sales tax on cleaning in Connecticut
Residential cleaning is taxable in Connecticut, and so is commercial cleaning. Janitorial work is on the state's list of taxable services, and the regulation that defines it applies whether or not the property is commercial. The exclusions are narrow, and I lay them out on the Connecticut sales tax on cleaning page along with the rules behind them.

How that tax gets reported on a return is a different question. I'm a bookkeeper, not a CPA, so filing questions go to your CPA.
Employees or subcontractors
For unemployment insurance, Connecticut decides whether a worker is an employee using the ABC test, found in Conn. Gen. Stat. 31-222(a)(1)(B)(ii). The Connecticut Department of Labor publishes its own explanation of the employer-employee relationship for unemployment taxes, linked below. In the books, a W-2 employee and a 1099 subcontractor land in completely different places, which I covered in 1099 subcontractors vs. W-2 employees.

Whether a specific person on your crew is an employee under that test is a legal call. Take it to your CPA or an employment attorney.
Registering for payroll in Connecticut
Connecticut taxes wages, and payroll for a cleaning company with crews involves two state agencies. State income tax withholding is run by the Connecticut Department of Revenue Services (DRS), and registration happens through the DRS online services portal. Unemployment insurance is run by the Connecticut Department of Labor (CTDOL), and employer registration starts at CTDOL's unemployment tax login page.

I record what each payroll run produces. The filings themselves belong to your payroll provider and your CPA.
Minimum wage in Connecticut
The Connecticut minimum wage is $16.94 an hour, effective January 1, 2026. On August 5, 2026 the Governor's office announced the next step: $17.48 an hour starting January 1, 2027, the result of the state's annual Employment Cost Index adjustment. If you price recurring contracts a year at a time, that January date touches every crew member paid near the floor.

What this means for your books
Both sides of the business are taxable, so the job I care about most is keeping the sales tax you collect out of your income. That money was never yours; it's owed to the state. When it sits in its own liability account, I can show you where every single number in that balance came from, invoice by invoice, and your profit and loss shows only what the business earned. I still split residential and commercial work into separate income lines, because the two can price and staff very differently even when the tax treatment matches.
Labor is the other number. With the wage floor moving to $17.48 in January, a quote built on $16.94 can stop working without anyone noticing. The job profitability estimator runs a job with your own labor rate, so you see it before the price goes out.
