What is the sales tax in Connecticut?

State rate: 6.35%

The state sales tax rate in Connecticut is 6.35%.

Connecticut's cities and towns do not impose additional sales taxes on top of the state rate.

Repair, installation and labor

Connecticut taxes only the services its statutes list. The Department of Revenue Services' list includes locksmith services, repair of electrical or electronic devices (including air conditioning and refrigeration equipment), and electrical or plumbing services to commercial, industrial and income-producing real property.

Who licenses locksmiths and the trades in Connecticut?

From each agency's own page. Check with your city or county for any local license as well.

Locksmiths: Connecticut Department of Consumer Protection

Connecticut requires anyone engaged in locksmithing to be registered with the Department of Consumer Protection under Conn. Gen. Stat. 20-691. Locksmithing means inspecting, installing, recombining, rekeying, servicing or repairing locks, with listed exemptions such as work at one's own residence.

Plumbing: Connecticut Department of Consumer Protection

The Department licenses plumbing and piping work in contractor and journeyperson classes. For example, the P-1 unlimited plumbing contractor license covers all plumbing and piping work as defined in Conn. Gen. Stat. 20-330.

Electrical: Connecticut Department of Consumer Protection

Connecticut requires electricians to hold a Department of Consumer Protection license to do electrical work, and the license goes to the individual rather than the electrical business.

HVAC / air conditioning: Connecticut Department of Consumer Protection (Heating, Piping, Cooling and Sheet Metal Work Examining Board)

Workers in heating, cooling and sheet metal must hold a Department of Consumer Protection license, and the Heating, Piping, Cooling and Sheet Metal Work Examining Board oversees the trade.

How does IntelliDrive OS fit Connecticut’s tax and paperwork?

What the software does today, nothing more. It does not file your returns or give tax advice.

One tax rate per shop

Add your rates under Settings → Tax Rates, then choose each shop’s default rate under Settings → Outlets, so every shop charges its own local rate.

All features

Records kept digitally

Invoices, receipts, signatures and photos are kept digitally for your records, and you can send a receipt to the customer by email or text.

Payment-link evidence

Payment links through your own account

Text or email a payment link through your own QuickBooks Payments, Square or Stripe account. On a payment-link sale the record keeps the customer’s signature, the terms they accepted, IP address and device, photos, and location when their browser shares it.

Payment processing

Stock by shop and van

Each shop, and each van you set up as its own location, keeps its own stock, with reorder points, counts and exact transfers between locations.

Inventory

Your team, hours and commission

Time clock, timesheets, pay rates and per-technician commission reporting, with role permissions and staff limited to their own shop.

Workforce

QuickBooks Online, when you choose

Push sales and payments from IntelliDrive OS to QuickBooks Online. It is a one-way push that you start yourself.

QuickBooks integration

Scheduling and dispatch (add-on)
