When should your business collect Sales Tax in Connecticut?

A business must collect sales tax in Connecticut if it has a sales tax nexus within the state. Nexus, a Latin word meaning “to bind or tie,” is essentially the concept that a business has a sufficient connection to a state, and is therefore subject to state sales tax laws. A nexus can be established either through a physical presence or an economic presence.

Connecticut Physical Sales Tax Nexus

Physical presence can be established in numerous ways. For instance, if a business has an office, warehouse, store, or other physical location in Connecticut, it has a physical presence. Furthermore, if an employee or independent contractor is operating in Connecticut, that could also establish a physical nexus.

Connecticut Economic Nexus: Revenue, Thresholds and Transactions

An economic nexus, on the other hand, can be established if a business has more than $250,000 in gross receipts and conducts 200 or more separate transactions within Connecticut.

Which services are taxable in Connecticut?

In Connecticut, the majority of services are not subject to sales tax. However, several are considered taxable. These include but are not limited to:

  • Services to industrial, commercial or income-producing real property
  • Computer and data processing services
  • Telecommunications services
  • Repair services to tangible personal property and certain motor vehicles
  • Motor vehicle towing and road service

Connecticut Sales Tax on Products: How to Calculate What Your Business Should be Charging

When calculating the amount of sales tax to charge, the process is relatively straightforward: multiply the total cost of the item or items by the Connecticut state sales tax rate plus the specific product/service sales tax(6.35%+X). This will give you the total amount of sales tax that should be added to the customer’s bill. 

For example, if a business sells a designer handbag priced at $1,000, the seller needs to charge a sales tax of $6.35 plus $7.75. The total sales price will then be $1,141.

How does the Connecticut clothing tax work?

Clothing sales tax is applied at a rate between 6.5% and 9.3% in Connecticut. But note that this sales tax only applies to clothing items and footwear priced at $50 or higher.

But Connecticut makes things interesting by taxing clothing and footwear priced at $1,000 or more at a higher rate of 7.75% (plus local sales taxes).
